Guanlong valve groove type signal soft-sealing gate valve utilizes the compensation effect of the elastic gate to produce a small amount of elastic deformation to achieve a good sealing effect. The groove type signal soft-sealing gate valve has the advantages of light switch, reliable sealing, good elastic memory and long service life. Remarkable advantages, grooved signal soft sealing gate valve products are widely used in pipeline lines of tap water, sewage, seawater, water treatment, environmental protection, construction, fire protection, petroleum, chemical industry, electric power, food, medicine, textile, shipbuilding, energy and other industries It acts as a regulating and shut-off device.
Generally, the groove type signal soft sealing gate valve of Guanlong valve often accumulates in the groove at the bottom of the valve due to foreign objects such as cement blocks, iron filings and other debris after the water flushing pipe, which is easy to cause the failure to close tightly and form a water leakage phenomenon. The bottom of the seated gate valve adopts the same flat-bottom design as the pipeline, which is not easy to cause debris accumulation and makes the fluid flow unobstructed.
Precision casting valve body
The valve body is made of precision casting, and the precise geometric dimensions make the inside of the valve body do not need to be processed at any time to ensure the sealing of the valve.
Valve plate lagging
The valve plate is made of high-quality rubber for the overall inner and outer covering. The first-class rubber vulcanization technology in Europe enables the vulcanized valve plate to ensure accurate geometric dimensions, and the rubber and ductile iron valve plate are firmly bonded, not easy to fall off and have good elastic memory.
“O” ring seal
Because the valve stem and valve cover are sealed with three “O” ring seals, the frictional resistance during switching can be reduced, water leakage can be greatly reduced, and the seals can be replaced without stopping the flow of the medium in the pipeline.
