Abstract

The utility model discloses a miniature manual two-position and five-way valve. A first hole on the top sleeve is communicated with a first inlet through the valve cavity, and a second hole on the lower sleeve is communicated with a second inlet through the valve cavity. The air inlet, arranged in the top and lower sleeve on the motion shaft, is communicated with the center of the valve cavity. Driven shafts are arranged in the top and the lower sleeves. A spring is positioned in the lower sleeve at the lower end of the driven shaft. A first seal ring with a damper on the top is fixed on the convex of the sleeve on the driven shaft. The groove of a second and a third seal ring is arranged in the central device of the driven shaft. The second seal ring is arranged next to the clearance between the end of the top sleeve and the convex in the middle of the valve cavity. The third seal ring is arranged next to the clearance between the end of the lower sleeve and the convex in the middle of the valve cavity. A cam handle with notches is arranged on the top end of the driven shaft. The utility model has the advantages of a well defined structure, easy to use, and long life cycle, which can be used in a plurality of channels, for example, the inflator for cars.

Description

Miniature two-position five-way manually operated valve

Technical field:

The utility model relates to a kind of valve.

Background technique:

The kind of existing valve is a lot, but because structure is a conventional structure, is generally a suction port, an air outlet, is difficult to satisfy the needs of special occasions (as the car inflator).

Summary of the invention:

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can satisfy the miniature two-position five-way manually operated valve that uses under the multichannel situation.

Technical solution of the present utility model is:

A kind of miniature two-position five-way manually operated valve, it is characterized in that: valve body is arranged, gas source inlet is set on the valve body, first, two pipe interfaces, first, two portings, valve pocket top is provided with Upper shaft sleeve, the valve pocket bottom is provided with Lower shaft sleeve, first through hole that communicates with first porting by valve pocket is set on the Upper shaft sleeve, second through hole that communicates with second porting by valve pocket is set on the Lower shaft sleeve, gas source inlet communicates with the middle part of valve pocket, be loaded on from moving mandrel, in the Lower shaft sleeve, overlap the spring that is installed in the Lower shaft sleeve from the moving mandrel lower end, adorn first seal ring from moving mandrel top, first seal ring is positioned on the boss of Upper shaft sleeve, the top of first seal ring is provided with back-up ring, be provided with from the middle part of moving mandrel and adorn second, the groove of three seal rings, the gap nearside of second seal ring between Upper shaft sleeve end and valve pocket middle part boss, the gap nearside of the 3rd seal ring between Lower shaft sleeve end and valve pocket middle part boss, the cam handle with recess is loaded on from the moving mandrel upper end.

The 4th seal ring is set between Upper shaft sleeve and the valve body, the 5th seal ring is set between Lower shaft sleeve and the valve body.

The utility model is rational in infrastructure, and can satisfy under the multichannel situations such as car inflator and use, and easy to use, long service life.

Embodiment:

A kind of miniature two-position five-way manually operated valve, valve body 1 is arranged, gas source inlet 2 is set on the valve body 1, first, two

pipe interfaces

3,4, first, two portings 5,6, valve pocket 7 tops are provided with Upper shaft sleeve 8, the valve pocket bottom is provided with Lower shaft sleeve 9, first through hole 10 that communicates with first porting 5 by valve pocket is set on the Upper shaft sleeve 8, second through hole 11 that communicates with second porting 6 by valve pocket is set on the Lower shaft sleeve 9, gas source inlet 2 communicates with the middle part of valve pocket 7, be loaded on from moving mandrel 12, in the Lower shaft sleeve, overlap the spring 13 that is installed in the Lower shaft sleeve 9 from moving mandrel 12 lower ends, adorn first seal ring 14 from moving mandrel 12 tops, first seal ring 14 is positioned on the boss of Upper shaft sleeve, the top of first seal ring is provided with back-up ring 15, be provided with from the middle part of moving mandrel 12 and adorn second, three seal rings 16,17 groove 18,19, the gap nearside of second seal ring 16 between Upper shaft sleeve 8 ends and valve pocket 7 middle part boss 20, the gap nearside of the 3rd seal ring 17 between Lower shaft sleeve 9 ends and valve pocket 7 middle part boss 20, the cam handle 22 with recess 21 is loaded on from moving mandrel 12 upper ends.The 4th seal ring 23 is set between Upper shaft sleeve 8 and the valve body 1, the 5th seal ring 24 is set between Lower shaft sleeve 9 and the valve body 1.

Working principle of the present utility model is: withstand on the handle 22 by spring 13 from moving mandrel 12, stir handle 22 and promptly change the angle of the recess 21 of cam handle, and drive slides up and down to top dead center or lower dead center from moving mandrel 12, seal ring 16,17 from moving mandrel 12 also changes the position location thereupon, thereby realizes switching on and off between its chamber and the chamber.

Gas source inlet 2 connects source of the gas among Fig. 1, when 22 groups on handle during to the A side, seal ring 16 is shut air flue, and just in time expose the gap between Lower shaft sleeve 9 ends and the valve pocket 7 middle part boss 20 position of seal ring 17, gas source inlet 2 communicates with second pipe interface 4, and gas enters pipe-line system; First pipe interface 3 communicates first pipe interface, 3 air inlets (emptying) with first porting 5 simultaneously.Opposite among Fig. 2 with Fig. 1, when 22 groups on handle during to the B side, seal ring 17 is shut air flue, and just in time expose the gap between Upper shaft sleeve 8 ends and the valve pocket 7 middle part boss 20 position of seal ring 16, gas source inlet 2 communicates with first pipe interface 3, and gas enters pipe-line system; Second pipe interface 4 communicates second pipe interface, 4 air inlets (emptying) with second porting 6 simultaneously.
