The groove gate valve overcomes defects such as rubber aging and rust. By utilizing the compensation effect of the valve elastic gate, small elastic deformation is generated, achieving good sealing effect. Trench gate valves have the advantages of reliable sealing, good elasticity, bright opening and closing, and long service life. Trench gate valve products are widely used as regulating and intercepting devices on pipelines in industries such as water treatment, medicine, textile, shipbuilding, environmental protection, tap water, firefighting, petroleum, chemical, sewage, seawater, construction, electricity, food, energy sources, etc.

Groove gate valve is a control unit for pipeline fluid transportation system, which is used to change the flow direction of channel sections and media, and has functions such as diversion, stop, throttling, check, diversion or overflow. A type of one-way valve fluid control, used in various types and specifications of valves from simple to complex automatic control systems. The nominal diameter of groove gate valves ranges from a very small instrument valve to an industrial pipeline valve with a diameter of 10m. Groove gate valves can be used to control various fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals, and radioactive fluids. Next, let's take a look at how to perform maintenance:

1. Packaging glands that are not skewed or pre approved are not allowed.

If the use of environmental inspection valves is poor, SMC air control valves are prone to contamination by rain, snow, dust, sand and other pollutants, and protective covers should be installed on the valve stems.

3. The instruments on the stainless steel SMC proportional valve should be kept complete, accurate, and clear, and the seals and valve covers should be inspected.

4. The insulation jacket should have no dents or cracks.

5. Run the groove butterfly valve to avoid jumping or support heavy objects.

6. Attention should be paid to checking the storage environment of the SMC pneumatic valve in the groove. It should be stored in a dry and ventilated room, and both ends of the channel should be blocked.

7. The groove gate valve should be regularly inspected for dirt and coated with anti rust oil on its surface.

8. Install and apply groove gate valves to handle daily maintenance and ensure their normal operation.

9. The sealing surface of the groove gate valve should be checked for wear and repaired or replaced according to the situation.

10. Check the threads of the valve stem and valve stem nut to see if the packing is expired and needs to be replaced.

11. Test the sealing performance of the groove gate valve to ensure its performance.

12. The operated Rexroth solenoid valve should be intact, the bolts on the flange and bracket should be intact, the threads should be undamaged, and there should be no looseness.

13. If the wheel is lost, it should be filled in a timely manner and the wrench should not be replaced.

The structure of groove gate valve body determines the connection between valve body and pipeline, valve body and valve cover. In terms of manufacturing methods, there are several types, including casting, forging, forging welding, casting welding, and pipe plate welding. The forging body has developed towards the direction of large diameter, while the casting body is gradually developing towards the direction of small diameter. Any type of gate valve body can be forged or cast, which should be determined according to the user's requirements and the manufacturing technology methods of the manufacturer.
