Abstract
The utility model discloses a manual air changing valve which is matched with a pneumatic control valve and a pneumatic force taking device. The manual air changing valve comprises a valve body, a valve sleeve, a sealed gasket, an end cover, a bottom cover, a valve shaft positioned in the valve sleeve, a handle lever connected with the valve shaft, and a handle ball, wherein the end cover and the bottom cover are positioned at the upper side and the lower side of the valve body, and the valve body and the valve sleeve are in a separate type structure. The valve sleeve is formed by assembling multilevel subordinate valve sleeves, and the sealed gasket is arranged between two adjacent subordinate valve sleeves. The air changing valve of the utility model adopts the technology of separating the valve body and the valve sleeve, and changes the original complicated inner bore processing into simple processing. The utility model solves the problem of difficult processing and measurement of the dimension of an inner bore sealing groove of the valve body without special equipment. Thus, the product quality is improved, and the production efficiency is increased.
Description
Technical field
The utility model relates to a kind of scavenging air valve, especially a kind of manual scavenging air valve that cooperates with pneumatic control valve, pneumatic power take-off.
Background technique
The scavenging air valve of Shi Yonging in the market, its valve body and valve pocket all are the structural type that adopts one.The seal groove of seal ring is installed, is had plenty of out on valve body inner bore, have plenty of out on the valve shaft cylindrical.But no matter adopt which kind of form, in valve body hole and on the valve shaft, all need to have simultaneously groove to exist, to guarantee the unimpeded of each gas channels in the product working procedure.Therefore when processing endoporus annular groove, often face the problem aspect following:
When one, in adopting valve body hole, seal ring being installed, higher to diameter dimension, the axial position size requirement of endoporus seal groove.And this product valve body inner bore is less, adopt the dedicated numerical control apparatus processing adding to have only man-hour, but the cutter consumption is higher, therefore causes the processing cost height; Because endoporus is less, check, measure very difficulty, the size that has does not have special-purpose laser class measuring equipment can't measure at all; Such seal form is very difficult when assembling endoporus seal ring on the other hand, and what have also can't assemble.
Two, when adopting the valve shaft cylindrical that seal ring is installed: not high to valve body inner bore diameter of ring groove size requirement, the size of seal groove is also processed easily and is guaranteed on the valve shaft, but owing to adopt the product of such sealing to need the seal ring move left and right in the course of the work, therefore chamfer shape, size and the surface roughness to valve body inner bore annular groove notch requires very high, otherwise seal ring as easy as rolling off a log generation in moving process damages phenomenon, causes product rejection.
Summary of the invention
It all is the problems referred to above that the structural type of employing one causes because of its valve body and valve pocket that the utility model is intended at existing manual scavenging air valve, provide a kind of valve pocket to adopt the manual scavenging air valve of split-type structural, adopt the utility model not need special device to be not easy the problem processing and measure with regard to having solved valve body inner bore seal groove size, not only improve quality of product, and improved manufacturing efficiency.
For achieving the above object, the technological scheme that the utility model adopted is as follows:
A kind of manual scavenging air valve comprises valve body, valve pocket, sealing gasket, it is characterized in that: described valve body and valve pocket are split-type structural; Described valve pocket is assembled by multistage sub-valve pocket, and sealing gasket is installed between the adjacent two sub-valve pockets.
The utility model also comprises and is positioned at valve body up and down end covers at two sides, bottom, is positioned at the valve shaft of valve pocket, handlebar that is connected with valve shaft and handle ball.
Described valve body is provided with the air outlet of suction port and suction port both sides, and suction port and the air outlet aperture on valve body respectively are communicated with valve pocket in the valve pocket.
Described valve shaft is provided with connection or closes the boss part and the annular groove portion of adjacent valve pocket passage.
Described handlebar side valve body is provided with ball grooves, and spring and ball are set in it, and the corresponding position handlebar is provided with the annular groove with the ball coupling.
Described suction port is positioned at the valve body medium position, and two air outlets lay respectively at both sides up and down; Valve pocket has Pyatyi sub-valve pocket side by side, establishes four sealing gaskets between each sub-valve pocket altogether; Valve shaft is established two annular groove portions of three boss part, and three boss part and four sealing gaskets are divided into three chambers with valve pocket, and three chambers are communicated with suction port, two air outlets respectively.
Advantage of the present utility model is:
The utility model scavenging air valve has adopted the technology that valve body is separated with valve pocket, the simple processing of endoporus processing having become with original complexity, do not need special device to be not easy the problem processing and measure with regard to having solved valve body inner bore seal groove size, not only improve quality of product, and improved manufacturing efficiency.

Embodiment
A kind of manual scavenging air valve comprises valve body 1, valve pocket 2, sealing gasket 3, is positioned at valve body end covers at two sides 4, bottom 5 up and down, is positioned at the valve shaft 6 of valve pocket, handlebar 7 that is connected with valve shaft 6 and handle ball 8.Described valve body 1 and valve pocket are split-type structural, and valve pocket is assembled by multistage sub-valve pocket, and sealing gasket 3 is installed between the adjacent two sub-valve pockets.
Described valve body 1 is provided with suction port 10 and air outlet 11, and suction port 10 is positioned at valve body 1 medium position, and two air outlets 11 lay respectively at both sides up and down, and valve pocket has Pyatyi sub-valve pocket side by side, establishes four sealing gaskets 9 between each sub-valve pocket altogether; Valve shaft 6 is established two annular groove portions of three boss part, and three boss part and four sealing gaskets are divided into three chambers with valve pocket, and suction port 10 and air outlet 11 aperture on valve body respectively are communicated with three chambers in the valve pocket.Described handlebar 7 side valve bodies are provided with ball grooves, and screw 9 springs 12 and ball 13 are set in it, and the corresponding position handlebar is provided with the annular groove 14 with the ball coupling.High-pressure air is gone up aperture by suction port 10, valve pocket 2III and is entered into valve pocket a.
One, when valve shaft 6 mediates, valve pocket a does not all communicate with valve pocket b, c, and valve pocket b, c all are in normal open state with atmosphere, and the high-pressure air in the controlled product is drained in the atmosphere by valve pocket b, c chamber.
Two, when handle pulls outward, drive valve shaft 6 is past together to move right, and by end cap 4 axial limitings.This moment valve pocket b with the plasmas channel blocking-up and with a chamber with communicate, high-pressure air flows to valve pocket b via valve pocket a, and flows to controlled product by pipeline after entering into the left end air outlet by aperture on the valve pocket 2II.This moment, valve pocket c and atmosphere were in normal open state.
