Tap water valves generally refer to civil valves.

At present, ordinary families are generally commonly used in the form of gate valves, ball valves, triangle valves, etc., which are generally made of iron or copper.

Because steel valves have the advantages of not being easy to rust and strong corrosion resistance, copper valves have gradually replaced iron valves. The surface of the triangle valve is basically electrogalvanized, which is not only used to control the flow of pipeline media, but also to play a decorative role. Triangle valves are generally used for water supply with connecting pipes and inlet hoses, and there are also connecting pipes and inlet hoses for water heater water supply.

Gate valves are basically used for the connection of pipes and water meters.

Ball valves are used to connect pipes and water heaters.

Because the opening and closing of the ball valve is more convenient than the gate valve, the current connection between the pipeline and the water meter is mostly the ball valve.

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

1.When purchasing, visually inspect the valve, and the surface should be free of trachoma; The surface of electroplating should be glossy and uniform, and attention should be paid to whether there are defects such as peeling, cracking, burning, exposed bottom, peeling, black spots and obvious pitting; The surface structure of the spraying should be fine, smooth and uniform, and there should be no defects such as sagging and exposed bottom. The above defects will directly affect the service life of the valve.

2.The pipe thread of the valve is connected with the pipeline, and the surface of the thread is visually inspected for obvious defects such as dents and broken teeth when purchasing, and special attention should be paid to the effective length of the pipe thread and the connector will affect the reliability of the seal, and the effective length of the pipe thread should be paid attention to when purchasing. Generally, the effective length of the cylindrical pipe thread of DN15 is about 10mm.

3.Gate valves and ball valves are generally marked with nominal pressure on their valve bodies or handles, and they can be selected according to their own needs when purchasing.

4.When replacing an existing gate valve or ball valve, it is necessary to find out the length of its structure so that it cannot be installed after purchase.

5.There are two kinds of pipe threads for triangle valves: internal threads and external threads, which should be purchased according to needs; It should also be noted that there are some zinc alloy triangle valves on the market, which are sold at a lower price than ordinary products, but are prone to corrosion and fracture.

Should try to buy in regular building materials stores and supermarkets, so that the quality of the products can be guaranteed.

Follow-up thank you! Is the water valve for the water pipeline durable or the air valve durable.

Of course, the same material valve will not be more durable than the gas pipe (natural gas), and the valve on the gas pipeline should be a copper ball valve (more special for gas).

In fact, the brand of the valve still has certain difficulties in choosing, because each valve brand has its own advantages, in fact, among the many valve brands, I personally think that the products of the brand of Langao valve are very good, and this brand has a very innovative technical concept, and the product is also very novel in terms of design. The most important thing is that the popularity of this brand is also very high.

In fact, the new Tyrone valve (joint venture) on the market is also good. Affordable, and more importantly.

Huiquan valve in Dandong, Liaoning Province, is low cost and quality assurance.

What brand of valve is good? I think as long as the user has the most right to speak: Osilom brand valve***.

AMICO's brass valves are of good quality and well-known in the industry.

It depends on your actual operating conditions. What media you want to go through, what environment, what kind of working conditions and other parameters to choose. The tightness of the ball valve is generally better. Lidian valve industry, the achievement of classics.

Hello! Mainly look at the medium, their copper valves are OK.

In fact, the brand of the valve still has certain difficulties in choosing, because each valve brand has its own advantages, in fact, among the many valve brands, I personally think that the products of the brand of Langao valve are very good, and this brand has a very innovative technical concept, and the product is also very novel in terms of design. The most important thing is that the popularity of this brand is also very high.

I really don't dare to say that kind of brand is good: some well-known brands are OEM by domestic small enterprises!

The main thing is that this valve should be easy to use.

There are still a lot of good brands of valves, such as Langao Valve, Jiangyi, Emeco, Lipai, Open Valve, Beijing Brand, SF, are very good, if the landlord has time, you can buy Chinese brands on the Internet to see, the above brand information is very good, it is very helpful to buy, to understand it.

I know there's a good Tyrone valve. The quality of Shanghai's is not generally good. You can find it on the Internet.

It is recommended that you use the valve of the Oslun pump valve***.

I know that the valves of Shanghai Lianggong are not bad.

In fact, the new Tyrone valve (joint venture) on the market is also good. Affordable, and more importantly.

It depends on what the valve.

The number of high temperature and high pressure valves is the core Su valve, the safety valve is still better in AVIC, the steam trap is Gansu Hongfeng Machinery, and the flat gate valve is still the Chengdu Chengfeng valve.
