Embodiment Construction
[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0017] refer to figure 1 , 2 3. A high-pressure multi-seal multi-seal porous damping speed-reducing channel structure, including a multi-section partial pressure, speed-limiting, flow-dividing damping sealing orifice plate 3, the main body of which is a cylindrical structure, and the speed-limiting flow is uniformly distributed in the height direction of the cylindrical structure The damping hole 3-3 has a sealing ring groove 3-2 on the upper and lower surfaces close to the outer edge, and a sealing ring 2 is installed in the sealing ring groove 3-2; the cylindrical surface of the cylindrical structure is opened There are several multi-section pressure-dividing medium annular grooves 3-1, in which sealing rings are installed.
[0018] If the medium flows into the medium buffer zone 1-1 of the upstream channel of the valve body, the sealing ...

A high-pressure multi-seal porous damping speed reduction channel structure comprises a multi-section pressure-dividing speed-limiting flow-dividing damping sealing pore plate, a main body of the multi-section pressure-dividing speed-limiting flow-dividing damping sealing pore plate is of a cylinder structure, speed-limiting flow-dividing damping holes are evenly distributed in the height direction of the cylinder structure, sealing ring annular grooves are formed in the positions, close to the outer edge, of the upper surface and the lower surface of the cylinder structure, sealing rings are installed in the sealing ring annular grooves, a plurality of multi-section pressure-bearing and pressure-dividing medium annular grooves are formed in the cylindrical surface of the cylinder structure, and sealing rings are mounted in the annular grooves. Under the working condition of high pressure and high flow velocity, good sealing of the joint is effectively guaranteed, erosion of scouring to a valve cavity is reduced, the service life of a valve is prolonged, the working efficiency is improved, and the cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of general manufacturing, and in particular relates to a high-pressure multi-seal porous damping speed-reducing channel structure. Background technique [0002] Nowadays, with the maturity of industrialization, there are more and more types of valves used in various working conditions. Among them, more and more valves are used in the high-pressure field. When the pressure difference between the front and back of the fluid is large under high-pressure conditions, the flow rate of the medium will also increase with the change of the pressure difference. The high pressure and high flow rate of the medium will lead to leakage at the connection due to high pressure; the high flow rate will cause the valve cavity to be washed and the service life will be seriously reduced. When there is a seal leakage problem in the medium under high pressure conditions, it will cause serious accidents. Contents of the inventio...
