Example Embodiment

[0028] Example 1:

[0029] As attached figure 2 , 3 As shown in Figure 4, a high-pressure valve of the present invention mainly includes a valve body 2 connected to a pipeline through which fluid flows in the horizontal direction. The valve body 2 is connected to the side valve covers 10 and 12 equipped with the valve plates 16, 18 An accommodating space is formed in the accommodating space, and the spool sleeve 30 is arranged in the accommodating space. The spools 32 and 34 are arranged in the spool holes at both ends of the spool sleeve 30. The spools 32 and 34 are pressed into the spool together with the springs S1 and S2 respectively. In the hole, the valve cores 32 and 34 are in contact with the sliding sealing surfaces 24 of the valve plates 16, 18, and the valve core sleeve 30 can be raised and lowered in the containing space. The lower part of the valve stem 36 is connected to the valve core sleeve 30 and the upper part is connected to the driving device 14 to drive The d...

Abstract

The invention relates to high pressure valve. It includes valve body and setting space formed by valve body, port plate, and side valve cover. Its features are as follows: the setting space is set valve core cover, valve core, and spring; the two ends of the cover are set valve core hole; and the cover body is set through flow hole. And it can be formed switch to realize valve bar safe force balance and sealed self compensation. This not only can increase valve response speed, but also can improve sealing performance.

Description

1. Technical Field: [0001] The invention relates to a high-pressure valve used in a pipeline for conveying high-pressure fluid, in particular to a high-pressure valve used in a pipeline for transporting high-pressure fluid, particularly a kind of restricting the fluid flow in the pipeline, restricting the fluid flow with a small driving force, making opening and closing easy, and having a pressure seal High pressure fluid shut-off valve with compensation function. 2. Background technology: [0002] The valve is a component that restricts the flow and pressure of the fluid flowing in the pipe. Depending on the application purpose, it can be divided into shut-off valves, check valves, pressure reducing valves, etc. [0003] The above-mentioned shut-off valve cuts off fluid flow, and there is a shut-off valve. The two ends of the valve body of the stop valve are fluid inlet and outlet, and the inlet and outlet are flanges. A sealing valve seat is arranged on the horizontal center li...
