Problems solved by technology

However, the response speed of the existing valves is slow, and the sealing effect is not good during long-term continuous use, and it is easy to leak air. At the same time, due to the internal environment of the high-pressure gas pipeline, the check valve is easily damaged, resulting in high-pressure gas leakage, causing losses, and even production accidents.

Embodiment Construction

[0021] Such as Figure 1~4 As shown, a mechanical valve of the present invention includes a tubular casing 103, and one end of the casing 103 is provided with a right head 101 and a left head 104; two vents 102 are arranged on the side wall of the casing. The housing 103 is provided with a piston that can slide axially along the inner wall of the housing 103; the piston includes a piston tube body 105 with an outer diameter smaller than the inner diameter of the housing 103, and circular slide plates 106 fixed at both ends of the piston tube body 105 , the outer circumference of the sliding plate 106 is sealed with the inner wall of the casing 103 . The two vents 102 are disposed on the side wall of the casing 103 and located between the two sliding plates 106 . A sealing baffle 108 is provided on the side of the air vent 102 close to the piston body 105, and the sealing baffle 108 can press the sealing ring 109 located on the inner wall of the housing 103 and sleeved on the ...

Abstract

The invention discloses a mechanical valve which comprises a tubular shell, a piston in the shell and a mechanical control structure which is located between the shell and the piston and can control a ventilating opening to be opened and closed. By the adoption of a purely mechanical valve opening and closing control structure, the mechanical valve is correspondingly high in response speed. By the mutual action force between a roller and a sealing baffle, a sealing ring is pressed, so that relatively high pressing force is generated on the sealing ring, and a good sealing effect is achieved; furthermore, in a repeated opening and closing process, the structure is high in stability and cannot fail; the piston is of a cylindrical structure, and sliding plates and sliding rings are arranged at the front and rear ends for supporting and sliding; and the structure is relatively symmetric and relatively stable.

Description

technical field [0001] The invention relates to the field of valves, in particular to a mechanical valve. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, duplex steel valves, plastic valves, non-standard custom valves and other valve materials according to the material.
