Quick Discharge Gate Valve

A pipeline control equipment evolved from gate valves, which achieves rapid opening and closing by driving the valve stem up and down through gear rotation of 90 °. It has the characteristics of compact structure, strong sealing, and low operating torque. The valve core guide seat and throttle hole are designed to form a vortex self-cleaning sealing surface during discharge, which is suitable for efficient impurity discharge in systems such as boilers and industrial pipelines. The material can be selected from pressure resistant alloys such as cast steel to meet the requirements of high temperature and high pressure working conditions.

Standardization adaptability

Standardization adaptability
01
Compliant with standards such as GB/T12237 and JB/T6900, the flange size is compatible with conventional pipeline systems and suitable for industrial boilers and municipal pipeline networks with PN ≤ 2.0MPa.

Multi channel sewage discharge capacity

Multi channel sewage discharge capacity
01
Supporting single channel or five channel synchronous discharge, the guide seat and throttle hole cooperate to form a stepped discharge path, improving the efficiency of boiler sludge discharge.

Modular compact structure

Modular compact structure
01
The clamp type valve body connection design reduces the overall weight by 20%, reduces leakage points at the branch pipe welding interface, and supports non-stop maintenance.

Quick opening and closing with low operating torque

Quick opening and closing with low operating torque
01
The gear driven valve stem can rotate 90 degrees to complete the lifting action, and the switch status is visualized. The operating torque is reduced by 30% -50% compared to traditional valves.

Pressure self tightening sealing structure

Pressure self tightening sealing structure
01
The asbestos packing sealing ring enhances its sealing performance with the increase of medium pressure, combined with a dual seal design to achieve zero leakage, and the self-cleaning function of the sealing surface vortex can prevent impurities from adhering.

High strength and corrosion-resistant material

High strength and corrosion-resistant material
01
Made of copper alloy, cast steel or stainless steel material, the valve disc is treated with boronization, which can withstand high temperature and high pressure working conditions and effectively resist medium erosion.
