Abstract
The utility model relates to a plane seal lever push opening type valve, which is used for a filling insertion system of an air-jet loom, belonging to the technical field of the textile machinery. A push-opening lever which is connected with a lever and provided with a guiding ring and a seal pad is arranged in the valve body. A return spring is arranged on the top end of the push-opening lever. The return spring supports a bulkhead which is arranged on the valve body. The utility model has simple, compact and rational structure, and longer operating life than the existing machine valve. The plane seal lever push opening type valve can be used for two to five hundred millions times, the working frequency is as high as 400 to 800 times per minute, the price is lower than the price of an electromagnetic valve, and the cost is about one-tenth to one-third of the cost of the electromagnetic valve; the electric control component is simplified greatly, and the performance is reliable and stable. The utility model can implement the dependable plane soft seal.
Description
Technical field
The utility model relates to a kind of plane sealing lever top-opening type valve, is used for the weft insertion system of air-jet loom, belongs to the textile manufacturing machine equipment technical field.
Background technique
Before the utility model is made, in prior art, normally adopt mechanical valve to carry out linear sealing or ball face sealing in the weft insertion system of air-jet loom.Lack in mechanical valve machining accuracy height, working life, arrive between millions of times at tens thousand of times, frequency of okperation is lower, incompatibility high frequency, long lifetime requirement.Under the occasion tight at seal request, that frequency of okperation is high, the life-span is long, can only adopt to cost an arm and a leg, control complicated solenoid valve.Therefore, manufacture cost is higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provides a kind of simple, compact and reasonable for structure; Seal reliable, with low cost, the plane sealing lever top-opening type valve of long service life.
Main solution of the present utility model is achieved in that
The utility model mainly adopts in valve body 5 to install and backs down bar 4, backs down bar 4 and connects levers 2, guide ring 9, sealing gasket 8 is housed backing down on the bar 4, and Returnning spring 7 is contained in and backs down bar 4 tops, and Returnning spring 7 withstands plug 6, and plug 6 is installed on the valve body 5.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Than existing machinery valve long working life, can reach 2-5 hundred million times, frequency of okperation up to 400-800 time/minute; Lower than solenoid valve price, the 1/10-1/3 that is about electric valve cost does not wait, and electric controling part is greatly simplified; Reliable performance is stable, can the soft seal of practical and reliable plane.

Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly by bearing 1, lever 2, fulcrum 3, back down bar 4, valve body 5, plug 6, Returnning spring 7, sealing gasket 8, guide ring 9 etc. and form.Employing is installed in valve body 5 and is backed down bar 4, backs down bar 4 and connects lever 2, adopts bearing 1, bearing pin fastening lever 2, and fulcrum 3 is fixed on the lever 2.Guide ring 9, sealing gasket 8 are housed backing down on the bar 4, Returnning spring 7 is contained in and backs down bar 4 tops, and Returnning spring 7 withstands plug 6, and plug 6 is installed on the valve body 5.
The utility model adopts lever construction to realize the breakdown action of air valve.Bearing 1 drives lever 2 under external force and moves downward around fulcrum 3, lever 2 the other ends then upwards move, promotion is backed down bar 4 and is asked and ask motion in the ring leading, and compression reseting spring 7, sealing gasket 8 with back down bar 4 move upward the back and valve body 5 between form the gap, the pressurized air that the suction port place comes passes through from the gap, arrives the air outlet.In the utility model lever 2 and fulcrum 3, to back down between bar 4 and the guide ring 9 surface friction drag minimum, guarantees long lifetime work.Air valve open-interval length is controlled by external force, and when needs closed gas check valve, external force was cancelled, and backs down bar 4 under the acting in conjunction of Returnning spring 7 and air inlet back pressure, moves down rapidly to reset, and satisfies the high frequency requirement.Sealing gasket 8 tightly is combined together with valve body 5, thereby can realize the soft seal of reliable plane.
