Description

A ceramic wear-resistant valve sealing device

Technical Field

The present application relates to the field of valve technology, and in particular to a ceramic wear-resistant valve sealing device.

Background Art

Valves commonly used in various industries in China are metal valves. The use of metal valves has a history of hundreds of years. Although metal valves have been improved in structure and materials, they are limited by the properties of metal materials and cannot adapt to the needs of increasingly severe working conditions such as high wear and corrosion. They are mainly reflected in short service life and serious leakage, which greatly affects the stability of system operation. Compared with metal valves, ceramic valves have better corrosion resistance and wear resistance, and are not easily affected by external conditions.

Ceramic valves will wear out after being used for too long, which affects the sealing of the valve. The structure of the traditional valve connection parts is relatively simple. When connected to the pipeline, usually only one sealing gasket is used for sealing. The sealing effect is poor. When the water pressure is too high, water seepage is likely to occur at the connection parts, resulting in a waste of water resources.

A ceramic wear-resistant valve sealing device comprises: a connecting ring connected between a connecting port of a valve and a pipeline, and an annular boss connected to an inner hole of the connecting ring and protruding from the corresponding end surface of the connecting ring at both ends, a first sealing member is respectively arranged on both sides of the connecting ring, the connecting port and the pipeline respectively contact with the corresponding first sealing member, an annular boss is respectively arranged on both sides of the connecting ring, and the connecting port and the pipeline are respectively sleeved on the corresponding annular bosses.

Furthermore, a sealing sleeve is provided on the outer periphery of the annular boss.

Furthermore, the outer peripheral surface of the annular boss has a taper, and the outer peripheral diameter of the annular boss gradually increases from the end to the root.

Furthermore, the cross-section of the connecting ring is an "I"-shaped structure, the first sealing member is located in the groove of the "I"-shaped structure, flanges are provided on the connecting port and the connecting end of the pipe, and the two side surfaces of the outer ring of the connecting ring are respectively connected to the corresponding flanges.

Furthermore, a second sealing member is respectively provided at both ends of the inner ring of the connecting ring, and the second sealing member is in conflict with the connecting port or the pipeline.

Furthermore, the first sealing member and the second sealing member are both sealing rings.

Furthermore, a first annular groove and a second annular groove are provided on both sides of the connecting ring, the first sealing member is embedded in the first annular groove, and the second sealing member is embedded in the second annular groove.

Furthermore, the connecting ring and the annular boss are connected by welding.
