Hydraulic control check eccentric hemispherical valve

PRODUCT OVERVIEW     

The hydraulic control check eccentric hemispherical valve adopts the structure of vertical upper open cover full diameter hemispherical valve. There is a certain eccentricity between the rotation center of eccentric crankshaft and the center of valve body. The sealing pair includes metal and non-metal seals. The connection form with the pipeline is flange connection. It is widely used in water conservancy, thermal power, water supply and drainage, chemical industry, metallurgy and other pump stations.

This series of products have reasonable design structure, high strength and no vibration at high flow rate. It can be opened according to the program. When it is opened, the flow channel is completely unblocked. During operation, the water loss is small. When it is powered off (or powered on), it will be automatically closed in two stages of fast closing and slow closing according to the preset time and angle. It is suitable for water, seawater, oil products, coal powder, coke oven gas, dusty gas and other media. It can be used for check and cut-off functions in the outlet or pipeline of the pump.

PRODUCT PERFORMANCE

1. It can replace the stop valve and check valve at the outlet of the water pump, and integrates machine, electricity and liquid, with small floor area;

2. During the opening or closing of the valve, the valve seat and ball crown do not rub against each other, and the service life of the valve is long;

3. The opening and closing of the valve is not affected by sludge and sundries, which is applicable to mud water conditions;

4. Metal and non-metal seals are adopted, with good self sealing performance. The greater the water pressure, the greater the sealing specific pressure;

5. High degree of automation, local, remote and linkage control;

6. The electrical system can adopt PLC intelligent control system or ordinary relay system;

7. The hydraulic system has the advantages of low motor power, high working efficiency, good pressure holding performance and long starting interval of oil pump;

8. It has obvious opening indication and mechanical limit adjustment mechanism, waterproof and dustproof design of travel switch device, no exposure, stable performance and long service life;

9. The electrical operation interface is humanized and diversified. It can be designed as ordinary button type, text type and touch screen type. It can also be designed according to the needs of customers.
