Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0031] refer to Figure 1-3 Shown is a schematic structural diagram of an intake valve with increased piston stroke according to an embodiment of the present invention, including a valve body 4, a casing 1, a cup-shaped diaphragm 2, a valve seat 11, a piston assembly and a butterfly valve.

[0032] Among them, refer to figure 1 As shown, the valve body 4 has an axial accommodation space with openings at both ends; The axial accommodation space communicates; the air outlet of the air intake pipel...

Abstract

The invention provides an air inlet valve capable of increasing the stroke of a piston. The air inlet valve comprises a valve body, a housing, a cup-shaped membrane, a valve seat and the piston. The valve body is of a axial containing space with the two open ends. The valve body is provided with an air inlet pipe and an air exhaust pipe, the air inlet pipe is used for being connected with an air compressor, and the air exhaust pipe is used for discharging remaining gas generated after unloading is preformed. The housing is arranged on one end of the valve body and integrally connected with thevalve body, so that one end of the axial containing space is sealed. The housing is provided with a cup-shaped structure with a containing space, and the housing and the valve body form a first cavity. The housing is provided with an air inlet which is used for introducing an air source into the housing. The cup-shaped membrane is matched with the housing in shape and arranged in the containing space of the housing, so that the housing and the first cavity form a sealing structure. The valve seat is arranged on the other end of the valve body and integrally connected with the valve body, so that the other end of the axial containing space is sealed. The piston is arranged in the housing, and a piston rod is arranged in the first cavity and can extend and retract in the first cavity. The air inlet valve can greatly increase the motion stroke of the piston.

Description

technical field [0001] The invention relates to the field of industrial valves, in particular to an intake valve capable of increasing the piston stroke. Background technique [0002] The intake valve is widely used in the field of industrial automation process. The intake valve is mainly used in the screw air compressor system to realize the opening and closing action of the intake valve, so as to switch or control the flow direction of the pipeline medium according to the change of system pressure. It is the purpose of intake capacity adjustment and so on. As the intake valve technology is more and more used in various industries, the performance of the original traditional intake valve is constantly improving, and it is urgent to develop new intake valve products that meet market requirements. The currently commonly used intake valve has a short piston stroke, which leads to greater wear and slow operation; and it cannot operate normally for a long time under oil-free co...
