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: what are their applicable conditions? Advantages and disadvantages?: The gate valve is one of the simplest valves. Generally manual, most of the electric valve failure, as a manual. Butterfly valve is more, I saw the pneumatic butterfly valve, that is, with gas control closed, general and solenoid valve matching.Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.

Q: What is a protective gate valve? What is gate valve knowledge?: Explosion-proof valve products, is a kind of safety valve can eliminate the shock wave which can stop the water hammer shock wave, it is a product composed of multiple sets of safety,

Q: Why does the fire hydrant box in the air defense area need to be added with gate valves?: Code for design of basement for civil air defence GB50038The installation and installation of the protective valve on the water supply line of the 6.2.13 air defense basement shall comply with the following requirements:OneWhen the water supply pipe from the entrance into, should be set up in the inner protective sealing door;

Q: What does gate valve do?: Gate valve structure, upstairs said about the same, but it can only rough adjustment flow, you may drive it to 30%, he will flow through 65% traffic, you can drive him to 70%, he also flow through 75% traffic. However, the fluctuation is small and can be used for rough adjustment of flow. What's more, half open and half closed are some of the effects on their life span.

Q: Notes on flat gate valves: Use, maintenance, maintenance and precautions1. valve before leaving the factory have made strength and sealing test, the use of all connections should maintain the initial state.2. this series of valve operating handwheel is marked with open and close rotary direction, and the upper part of rod is equipped with open and close height gauge for regulating indication.3. when the valve and pipeline welding, the valve should be opened, appropriate to protect the neck with moisture, minimize heat conduction, to prevent damage to the sealing packing parts.4. when the valve is closed, the lever shall not be used. When the gate is closed to the top, the handwheel shall be turned 1/2 so that the gate is in a floating state.5. in the use of the valve should be regularly to the valve cap injection grease joint into the quantitative grease.6., the valve in use, such as vulnerable parts and leakage, should be replaced in time.7., the valve in the overhaul process, the cavity should be cleaned, the assembly should be added to the transmission parts of grease.8. valve storage during the shutdown, the gate should be in the closed position, long-term storage should be placed in ventilated dry place, regular inspection and maintenance.
