Description

Technical Field

[0001] The utility model relates to the field of valve sealing parts, in particular to a valve self-sealing locking ring. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, and have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems, from the simplest shut-off valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. The self-sealing locking ring structure of the valve is one of the important and important components of the valve structure. To improve the self-sealing performance of the valve, it is necessary to further improve the materials and structures of the valve self-sealing part. The corresponding locking ring is designed according to the principles of fluid dynamics, and soft materials are used to improve the fit of the self-sealing locking ring structure. The accuracy of the corresponding parts is improved during the processing of parts. To this end, the utility model proposes a valve self-sealing locking ring to solve the above problems. Utility Model Content

[0003] The utility model aims to provide a valve self-sealing locking ring to solve the problems raised in the above background technology.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: a valve self-sealing locking ring, comprising

[0005] A valve body, wherein an outward-stretching rubber pad is arranged at the upper end of the valve body, and trapezoidal rubber pads are arranged at the left and right ends of the valve body.

[0006] A sealing disk, wherein a bolt rubber pad is arranged on the upper surface of the sealing disk, and an arc-shaped baffle is arranged below the sealing disk, and a corresponding groove-type rubber pad is arranged on the valve telescopic rod below the arc-shaped baffle.

[0007] An arc-shaped rubber pad is arranged at the connection between the valve body and the water pipe, and a tightening ring with a trapezoidal rubber pad is arranged on the outer side of the connection between the valve body and the water pipe.

[0008] Preferably, an outward-expanding rubber pad is provided at the upper end of the valve body, and when the outward-expanding rubber pad is fixed between the sealing disk and the valve body, it generates elastic deformation and fits between the valve body and the sealing disk.

[0009] Preferably, a bolt rubber pad is provided around the threaded hole on the upper surface of the sealing disk, and the bolt rubber pad is fixed to the surface of the sealing disk by bolts to be extruded and fixed to the surface of the sealing disk.

[0010] Preferably, the middle of the sealing disc is a valve expansion rod, and a grooved rubber pad is provided between the valve expansion rod and the valve sealing part. An arc-shaped baffle corresponding to the grooved rubber pad is provided on the surface of the sealing disc at the upper end of the grooved rubber pad.

[0011] Preferably, arc-shaped rubber pads are provided at the joints between the two ends of the valve body and the water pipe. The arc-shaped rubber pads are embedded between the valve body and the water pipe by the extrusion between the water pipe and the valve body. A tightening ring with a trapezoidal rubber pad is also provided on the outside of the joint between the valve body and the water pipe.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, the sealing performance between the sealing disc and the valve body is improved by arranging the outward-expanding rubber pad at the joint between the valve body and the sealing disc and by arranging the bolt rubber pad. A trapezoidal rubber pad is arranged inside the tightening ring. When the tightening ring is fixed and tightened by bolts, the trapezoidal rubber pad has a higher degree of fitting in the gap. By arranging an arc-shaped baffle below the sealing disc and a grooved rubber pad below the expansion rod, the gap between the expansion rod and the sealing disc is effectively sealed when the valve is opened. An arc-shaped rubber pad is provided between the water pipe and the valve body. When the internal pressure of the water pipe is greater, the rubber pad has a higher degree of fitting to the gap and stronger self-sealing performance. A tightening ring with a trapezoidal rubber pad is also arranged on the periphery to further improve the self-sealing performance between the water pipe and the valve body.
