Description
Technical field
The utility model relates to the horizontal one-way valve member of the one being applied to piston type air compressor.
Background technique
Horizontal one-way valve is one of vitals of air compressor, is the position control valve that control air compressor final exhaust duct internal pressure air-flow can not can only flow to opposite direction to a direction flowing.Simultaneously under the cooperation of other pressure controlled valves, during shutdown, automatic deloading can get rid of exhaust duct internal pressure, thus reach in zero load object of again starting, improve the reliability operation of air compressor.
Existing one-way valve, valve block (spool) common used material has nylon, metallic material, as nylon material, wear resistance and temperature tolerance poor, therefore impact resistance is poor, and the life-span is short.Metallic material valve block (spool) lift is little, and valve clearance aisle spare is little, and the pressure loss is large, as lift galling is also large, and the factors such as noise is large.Valve block (spool) guiding is inadequate, poor stability, affects valve block (spool) plane sealing.
Model utility content
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide in a kind of Miniature air-cooling presses air compressor high energy efficiency, long lifetime novel horizontal one-way valve.
Complete skill scheme of the present utility model is: a kind of horizontal one-way valve, comprises valve seat, valve body, joint and lift position limit socket.
Described valve body is arranged at the downside of valve seat, and the side that described joint is arranged on valve body is connected with valve body by screw thread, and described lift position limit socket is arranged on the bottom of valve seat, is connected with valve seat by screw thread.
Be provided with valve seat pad between described valve seat and valve body, described valve seat pad is connected with the internal thread of valve body upper end.
The connecting part of described lift position limit socket and valve body is provided with pad.
Described lift stopper is provided with the bore of Vertical direction, is provided with spool in described bore, is provided with spring bottom described spool.
Described joint and and valve body between be provided with joint gasket.
Preferably, described valve seat is hexgonal structure, and hexagonal divides into outside thread, outside thread and cylndrical surface and step are established in hexagonal bottom, valve seat upper and lower end through hole, and 1/4 spherical is established in aperture, upper end, sealing plane is established in aperture, lower end, and valve seat hexagon one side is provided with tapped hole.
Preferably, described spool is T-shaped structure, and upper end is sealing plane, peripheral chamfer; Lower end is cylindrical, is provided with endoporus.
Preferably, described lift position limit socket is hexgonal structure, and upper end is provided with outside thread, lower end is cylindrical.
Preferably, described valve body is cylindrical, and cylindrical center left bias establishes central through bore, and hole upper and lower end establishes interior threaded hole, and Cylinder inner bore is established in centre, and set a plane on the right side of valve body cylindrical, planar central sets an interior threaded hole and middle endoporus communicates.
The utility model compared with prior art has following beneficial effect:
1, have employed T-valve core, there is good steering capability and stability, ensure that seal spool plane keeps one's end up, improve the startability of unit, avoid the possibility burning out motor, improve the unfailing performance of air compressor, reduce the user cost of user.
2, have employed increase lift, improve valve clearance flow area, reduce the pressure loss of air-flow, avoid the shortcomings such as power consumption is large, achieve energy-conservation effect.
3, have employed the spool that special engineering plastics material makes, there is high strength, high abrasion, high-temperature resistant, the life-span of spool is improved greatly, horizontal one-way valve have structure simple, manufacture easy to maintenance, cost is low, high reliability, be worthy to be popularized.

Fig. 3 is valve core structure schematic diagram;
Wherein: 1, valve seat; 2, valve seat pad; 3, valve body; 4, joint gasket; 5 joints; 6, pad; 7, spool; 8, spring; 9, lift position limit socket.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
The present embodiment provides a kind of horizontal one-way valve, and structure as Figure 1-3, comprises valve seat 1, valve body 3, joint 5 and lift position limit socket 9.Described valve body 3 is arranged at the downside of valve seat 1, and the side that described joint 5 is arranged on valve body 3 is connected with valve body 3 by screw thread, and described lift position limit socket 9 is arranged on the bottom of valve seat 1, is connected with valve seat 1 by screw thread.
Be provided with valve seat pad 2 between described valve seat 1 and valve body 3, described valve seat pad 2 is connected with the internal thread of valve body 4 upper end; Described lift position limit socket 9 is provided with pad 6 with the connecting part of valve body 3; Described lift stopper 9 is provided with the bore of Vertical direction, is provided with spool 7 in described bore, is provided with spring 8 bottom described spool 7; Described joint 5 and and valve body 3 between be provided with joint gasket 4.
Described valve seat 1 is hexgonal structure, and hexagonal divides into outside thread, and outside thread and cylndrical surface and step are established in hexagonal bottom, valve seat 1 upper and lower end through hole, and 1/4 spherical is established in aperture, upper end, and sealing plane is established in aperture, lower end, and valve seat hexagon one side is provided with tapped hole; Described spool 7 is T-shaped structure, and upper end is sealing plane, peripheral chamfer; Lower end is cylindrical, is provided with endoporus; Described lift position limit socket 9 is hexgonal structure, and upper end is provided with outside thread, lower end is cylindrical; Described valve body 3 is cylindrical, and cylindrical center left bias establishes central through bore, and hole upper and lower end establishes interior threaded hole, and Cylinder inner bore is established in centre, and set a plane on the right side of valve body cylindrical, planar central sets an interior threaded hole and middle endoporus communicates.
