What are the characteristics of China sluice gate valve products?
The gate valve is a gate for opening and closing. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually, the sealing surface will be welded with metal materials to increase the wear resistance. The gate has a rigid gate and an elastic gate. According to the difference of the gate, the gate valve is divided into a rigid gate valve and an elastic gate valve. So do you know what its characteristics are? Let's follow the editor of China sluice gate valve products to have a simple understanding!
1. Light weight
The body is made of nodular cast iron, the weight is about 20%-30% lighter than the traditional gate valve, and it is easy to install and maintain.
2. Flat bottom brake seat
Traditional gate valves often deposit in the grooves at the bottom of the valve due to foreign objects such as stones, wood, cement, iron filings, sundries, etc., after the pipe is flushed with water, which can easily cause water leakage. The bottom of the gate valve is sealed by elastic seating. It adopts the same flat-bottom design as the water pipe machine, which is not easy to cause debris siltation and makes the fluid flow unimpeded.
3. Overall encapsulation
The gate adopts high-quality rubber for integral inner and outer rubber. European rubber vulcanization technology enables the vulcanized gate to ensure accurate geometric dimensions, and the rubber and ductile cast gate are firmly connected, not easy to fall off, and have good elastic memory.
4. Precision casting valve body
The valve body adopts accurate casting, and the accurate geometric dimensions make the inside of the valve body without fine machining to ensure the sealing performance of the valve.
In summary, the editor of China sluice gate valve products describes the characteristics of gate valves and related knowledge. I hope you can learn more.
