Q:What is plug welding gate valve?

Plug connection pipeline welding mode safety gate valve

Q:Analysis of the advantages of elastic seat sealing gate valve?

General valve on the market for a long time there is Water Leakage or rusting, overcome the valve seal bad, rust and other defects, using the elastic elastic valve seat seal gate produce small quantities of elastic deformation of the compensation function to achieve a good sealing effect, with a switch to lighter and reliable sealing, good elastic memory and life and other significant advantages. The utility model can be widely used as an adjusting and intercepting device for pipelines such as water supply, sewage, building, petroleum, chemical industry, food, medicine, light industry, electric power, ship, metallurgy, energy system, etc.. This is the advantage and advantage of an elastic seat seal gate valve.

Q:What are the advantages and disadvantages of flat gate valves?

The advantage of flat gate valve is that the flow resistance is small, and the flow resistance is similar to the flow resistance of short valve. The flat gate valve with guide hole is installed on the pipeline and can be directly cleaned with the cleaner. As the gate is sliding on the two seat surface, the flat gate valve can be applied to the medium with suspended particles, and the sealing surface of the flat gate valve is actually positioned automatically. The seat seal surface is not subject to thermal deformation of the valve body. Moreover, even if the valve is closed in cold condition, the thermal elongation of the stem will not cause the seal to be subjected to overload. The length of the structure is much shorter than that of the ball valve, and it is easier to start. Light plate gate valve is more refined, but the effect is exactly the same.The disadvantage of flat gate valve is that when the medium pressure is low, the sealing force of the metal sealing surface is insufficient, so as to achieve satisfactory sealing. On the contrary, when the medium pressure is high, if the sealing surface is not lubricated by the system media or foreign media, often opening and closing may cause the sealing surface to wear too much. Another disadvantage is that the circular motion of the circular gate in the circular flow, only when it is at the valve closed position of 50%, this valve is more sensitive to flow control. Moreover, the gate will produce severe vibration when it breaks the high-speed and dense medium flow. The valve seat can also be throttled if the seat is made of a V - shaped opening and is tightly oriented to the gate.

Q:About fire valve is gate valve or butterfly valve problems?

Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.

Q:What is the difference between the copper gate valve and the ordinary material gate valve?!

The material of general gate valve is cast iron, and the copper gate valve should be used in special requirement.

Q:Acid resistant alkali valve gate valve

D is small in shape and beautiful in appearance.E operation is simple and labor-saving.

Q:Which is more expensive, bronze gate valve or brass gate valve?

But the obvious weakness of brass is its poor strength, relatively large volume, and its lack of corrosion resistance.

Q:Is the gate valve clockwise or closed?

In general, the valve is clockwise turn off, in the case of special requirements under the opening.

Q:What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve

Yes. Globe valves and gate valves are indeed common in certain piping and operating conditions.
