Slag discharge check valve

Product Introduction 】 :

PH44H slagging check valve standard in line with DL/T530, "hydraulic ash removal and slag removal technical conditions" The product is suitable for thermal power plant water ash removal system, metallurgy, industrial steelmaking, dust sewage treatment, rolling iron sweat treatment, coal slag, water slag treatment and mining industry beneficiation pipeline as a closing device.

【 Working principle 】 :

PH44H slag discharge check valve adopts rocker arm swing structure, the valve disc rotates around the rotating shaft, the valve disc opens under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the pressure on the inlet side is lower than that on the outlet side, the valve disc automatically closes under the action of factors such as fluid pressure difference and gravity to prevent fluid backflow.

【 Product Features 】 :

1, the valve body outlet flow channel junction is reasonable, no slag, flexible opening and closing, no blockage.

2, the valve disc rotates around the pin outside the seat to reduce the violent impact when closed.

3, the pin and the valve disc are connected with the built-in pin structure, which reduces the leakage point and makes the use of more reliable.

4. Various pipe flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.

5, the sealing surface of the valve disc and seat is made of hard alloy surfacing, wear resistance, high temperature resistance, good abrasion resistance and long service life.

6, the body material variety is complete, fillers, gaskets according to the actual conditions or user requirements reasonable selection, suitable for a variety of pressure, temperature and medium conditions

The slag discharge and check valve is mainly suitable for conveying pulp, mortar and sewage in mining, metallurgy, electric power, chemical industry, sewage discharge and other industries with operating temperature of no more than 6.4MPa and ≤200℃.
