Question 1: Which brand of household water valve is best? It depends on what kind of valve you want, such as ball valve, butterfly valve, gate valve, faucet, etc. The valve brands include: Taichen Valve,

Huan Qi plastic pipes are mostly of good quality. Faucets include Moen, Kohler, Jiumu, Shenluda and many other well-known brands

Question 2: Which is the best brand of household tap water valves? Tap water valves generally refer to civilian valves

p>

At present, gate valves, ball valves, triangle valves and other forms commonly used in ordinary households are generally made of iron or copper.

Because steel valves have the advantages of being hard to rust and highly corrosion-resistant, copper valves have gradually replaced iron valves. The surface of the triangular valve is basically electro-galvanized. Its function is not only to control the flow of pipeline media, but also to play a decorative role. Triangular valves are generally used to connect pipes and water inlet hoses for water nozzles and toilets. They are also used to connect pipes and water inlet hoses for water supply to water heaters.

Gate valves are basically used to connect pipelines and water meters.

Ball valves are used to connect pipes and water heaters.

Since ball valves are more convenient to open and close than gate valves, ball valves are currently mostly used to connect pipelines and water meters.

Different types of valves should be selected according to the different requirements of users:

1. Visually inspect the valve when purchasing, there should be no blisters on the surface; the electroplated surface should have a uniform gloss, and attention should be paid to whether there are any Defects such as peeling, cracking, scorching, bottom exposure, peeling, black spots and obvious pitting; the sprayed surface structure should be fine, smooth and uniform, and there should be no defects such as sagging or bottom exposure. The above defects will directly affect the service life of the valve.

2. The pipe thread of the valve is connected to the pipe. When purchasing, visually inspect the thread surface for obvious defects such as dents and broken teeth. Pay special attention to the screwing of the pipe thread and the connecting piece. The effective length will affect the reliability of the seal. Pay attention to the effective length of the pipe thread when purchasing. Generally, the effective length of DN15 cylindrical pipe thread is about 10mm.

3. Gate valves and ball valves are generally marked with nominal pressure on their valve body or handle. You can choose according to your own needs when purchasing.

4. When replacing an existing gate valve or ball valve, it is necessary to find out its structural length to avoid failure to install it after purchase.

5. The pipe threads of triangular valves include internal threads and external threads, which should be purchased according to needs; it should also be noted that there are currently some triangular valves made of zinc alloy on the market, and the price of this valve is It is lower than ordinary products, but it is easy to corrode and cause breakage.

You should try to purchase from regular building materials stores and supermarkets, so that product quality can be guaranteed.

Question

Thank you! Are water valves in tap water pipes more durable or gas valves?

Answer

The key to whether they are durable or not is the material of the valve. Of course, valves made of the same material will not be more durable on water pipes than on gas pipes (natural gas). ) are durable. Generally, the valves on natural gas pipelines should be copper ball valves (most of which are dedicated to gas).

Question 3: What brand of water main valve is the best for your home? The brand is not the most important, but the material is important. For example, give priority to bronze or stainless steel valves, and then consider more famous brands. Anyway, there are only a few valves, try to buy good ones.

Question 4: Which brand of household tap water valve is better? The DN15 ball valve is easier to use.

Question 5: Which brand to choose for household water valves depends on what kind of valves you want, such as ball valves, butterfly valves, gate valves, faucets, etc. The valve brands include: Taichen Valve,

Huanqi plastic pipes are mostly of good quality, and the faucets include Moen, Kohler, Jiumu, Shenluda and many other well-known brands

Question 6: Which brand of water ball valve is good? Is there any better brand recommendation? There are many good brands of water polo valves. Here are ten well-known brands. The top ten brands of valves are listed here for reference. In fluid pipeline systems, valves are control components whose main functions are to isolate equipment and pipeline systems, regulate flow, prevent backflow, regulate and relieve pressure.

1. Langao Valve (founded in 1966, a national high-tech enterprise, a well-known trademark in China, a famous trademark in Gansu Province, a famous brand in Gansu Province, and one of the top ten valve brands)

2 , Jiangyi (national high-tech enterprise, well-known trademark in China, famous trademark in Zhejiang Province, famous brand product in Zhejiang Province, one of the key enterprises in China's valve industry)

3. Amico (well-known trademark in China , one of the largest copper valve production and export bases in China, Zhejiang Famous Trademark, Zhejiang Famous Brand)

4. Gongpai (founded in 1946, Shanghai Famous Trademark, Shanghai Famous Brand, Industry Influence brand, a professional manufacturer of valves and valve electric devices)

5. Jingpai (a famous trademark in Beijing, a key state-owned enterprise manufacturing high and medium pressure valves and steam traps, one of the top 500 Chinese machinery companies )

6. Dagao (founded in 1956, a well-known trademark in China, a national high-tech enterprise, and the supporting unit for the localization of key valves for national key equipment)

7. Flying Ball (In 1958, one of the largest valve manufacturing enterprises in China, a high-tech enterprise, a famous trademark in Sichuan Province, and a famous brand in Sichuan)

8. Shangva SF (Vice Director of the Valve Branch of China General Machinery Association Long unit, one of the key enterprises in the national valve industry, one of the top ten valve brands in China)

9. Lipai (China Famous Trademark, Tianjin Famous Trademark, exempt from export inspection, integrating scientific research, production, sales, storage, A group company integrating transportation, import and export operations)

10. Valve opening (founded in 1959, high-tech enterprise, famous trademark of Henan Province, vice-chairman unit of China General Machinery Association, large-scale backbone enterprise )

I wonder if you have noticed that these valves are all old brands and were built relatively early. If there are any good brands to recommend, I would recommend the brand Amico. I remember that the water valve in my old house was from this brand. You may not believe it when you tell me. It has been used for more than ten years and has not been replaced. I highly recommend it.

Question 7: Which model of household tap water valve is better? The DN15 ball valve is easier to use.

Question 8: What is the best water valve that is frequently opened and closed? 80 points. Household valves currently commonly used in ordinary households generally include gate valves, ball valves, triangle valves, etc., generally made of iron or copper. Due to the good mechanical properties of copper alloy, which is not easy to rust and has strong corrosion resistance, copper valves have gradually replaced iron valves.

The surface of triangular valves is basically electroplated. Its function is not only to control the flow of pipeline media, but also to play a decorative role. Triangular valves are generally used to connect pipes and water inlet hoses for water nozzles and toilets. They are also used to connect pipes and water inlet hoses for water supply to water heaters. Gate valves are basically used to connect pipelines and water meters; ball valves are used to connect pipelines and water heaters; because ball valves are more convenient to open and close than gate valves, ball valves are currently mostly used to connect pipelines and water meters.

Question 9: What are the famous Chinese brand household water supply valves? It's a mess, no authoritative organization has released it, and you can see completely different versions on the Internet. They are all on the list of the top ten valve brands in China in 2011. But none of them are the same.
