Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of cooling gas check valve provided by the utility model.
Embodiment
Core of the present utility model is to provide a kind of cooling gas check valve, effectively can reduce the rate of decay of valve hole part, improves the working life of cooling gas check valve.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of embodiment of cooling gas check valve provided by the utility model.
In a kind of embodiment, cooling gas check valve provided by the utility model comprises valve seat 2, valve body 7, spring 5 with can seal with valve body 7 valve hole part 6 contacted, valve hole part 6 comprises spool 63 and sealing gasket 62, one end of sealing gasket 62 is connected with spool 63, valve hole part 6 can be connected with the inner wall sealing of valve body 7, sealing effect is realized by sealing gasket 62, valve hole part 6 and spring 5 are all positioned at the cavity of valve body 7, valve hole part 6 can move in the cavity of valve body 7, for opening and closing cooling gas check valve, one end of spring 5 is connected with valve hole part 6, the other end is connected with valve seat 2, spring 5 is for sutaining valve core components 6, and when cooling gas check valve is closed, valve hole part is resetted, O RunddichtringO 3 is adopted to carry out sealing (sealing gasket also can be adopted to seal) between valve body 7 and valve seat 2.
One end of valve seat 2 has blind hole, one end of spool 63 has directional post 631, the blind hole of valve seat 2 is socketed on directional post 631, and the resistance ring 4 be provided with between the blind hole of valve seat 2 and directional post 631 for being tightly connected, resistance ring 4 is embedded in the groove of directional post 631, the number of resistance ring 4 is 2, because resistance ring 4 can stop the gas in the blind hole of valve seat 2 to flow out, therefore between directional post 631 and blind hole, forms a buffer air bag 8.Certainly, the number of resistance ring 4 also can be 1 or 3 or other numbers, here it should be noted that, when the number of resistance ring 4 is less, its sealing effect is poor, affects the formation of buffer air bag 8, when the number of resistance ring 4 is more, the very good meeting of sealing effect causes the travelling speed of directional post 631 in blind hole excessively slow, affects the using effect of cooling gas check valve, best results when therefore the number of resistance ring 4 is 2.
In working procedure, when the pressure of inlet end pressurized gas is greater than the active force of spring 5, pressurized gas is entered by the inlet end of valve body 7 and backs down valve hole part 6, gas flows through through valve hole part 6 periphery, now because the existence of buffer air bag 8 effectively reduces the movement velocity of valve hole part 6 towards valve seat 2, thus avoid the fast ram of valve hole part 6 and valve seat 2 end face when one-way valve is opened, when the pressurized gas air pressure of inlet end declines fast or the gas pressure of outlet side rises fast, spring 5 reset strap movable valve plug parts 6 reset, valve hole part 6 is at spring 5, move under the acting in conjunction of buffer air bag 8 and pressurized gas, again seal with valve body 7 air inlet port after valve hole part 6 resets and contact, namely venting channels is closed, now due to the existence of buffer air bag 8, reduce the movement velocity of valve hole part 6 towards valve body 7 inlet end, thus when reducing closed check valve, the quick washing of valve hole part 6 pairs of valve body 7 inlet ends, effectively avoid the impact force of valve body 7 suffered by valve hole part 6.
From above-mentioned working procedure, cooling gas check valve provided by the utility model, on the basis of existing technology, adds directional post 631 and resistance ring 4, and is provided with blind hole in one end of valve seat 2.After directional post 631 inserts the blind hole of valve seat 2, under the effect of resistance ring 4, form a buffer air bag 8 between the blind hole of directional post 631 and valve seat 2, under the effect of atmospheric pressure, buffer air bag 8 can effectively reduce the movement velocity of valve hole part 6.When cooling gas check valve is opened, directional post 631 moves towards valve seat 2, gas in blind hole is compressed, the atmospheric pressure in blind hole is caused to be greater than the atmospheric pressure of blind hole outside, therefore directional post 631 is difficult to continue to move towards valve seat 2, effectively reduce the travelling speed of directional post 631, thus avoid the fast ram of valve hole part 6 and valve seat 2 end face; When cooling gas check valve is closed, directional post 631 moves towards the direction away from valve seat 2, the gas pressure intensity in blind hole is caused to be less than atmospheric pressure outside blind hole, therefore directional post 631 is difficult to continue to move towards the direction away from valve seat 2, effectively reduce the travelling speed of directional post 631, thus avoid the fast ram of the air inlet end face of valve hole part 6 and valve body 7.Cooling gas check valve provided by the utility model effectively reduces the damage caused because of fast ram of valve hole part 6, considerably improves the working life of cooling gas check valve.
In order to better improve the using effect of cooling gas check valve, valve hole part 6 can be improved further.
61 parts are overlapped further for valve hole part 6 increases rectification, rectification cover 61 is connected with sealing gasket 62, and sealing gasket 62 overlaps between 61 at spool 63 and rectification, the cross sectional area of rectification cover 61 successively decreases to the side away from sealing gasket 62 from the side near sealing gasket 62, be specifically as follows circular cone shape, rectification is overlapped 61 inside and is also provided with the cavity inserted for spring 5, in addition, further the one side away from directional post 631 of spool 63 is designed to cross sectional area successively decrease to away from directional post 631 near directional post 631, be specifically as follows the combination of " conical surface+arc surface+conical surface ", this structural design not only can make valve hole part 6 in streamlined, valve hole part 6 can also be made better to fit with the inwall of valve body 7, ensure the tightness of cooling gas check valve.When gas flow is through valve hole part 6, air-flow is steady, eliminates the possibility that electric shock occurs valve hole part 6, can effectively reduce the noise of cooling gas check valve.
After valve hole part 6 adds rectification cover 61, spring 5 can be inserted in the inner chamber of rectification cover 61, and be socketed on directional post 631, this structure can save space, is convenient to gas better flowing in valve body 7.
Cooling gas check valve provided by the utility model can be provided with valve gap 1 further, also O RunddichtringO 3 is adopted to carry out sealing (sealing gasket also can be adopted to seal) between valve gap 1 and valve seat 2, to ensure the tightness of cooling gas check valve, in addition, adopt between valve gap 1 with valve body 7 and be threaded, make the assembling of this cooling gas check valve very simple.
One end away from blind hole of valve seat 2 is also provided with water conservancy diversion through hole 9, and gas flows into from the inlet end of valve body 7, and by being flowed out by the outlet side of valve gap 1 after water conservancy diversion through hole 9, water conservancy diversion through hole 9 is arranged on the position of departing from valve seat 2 center, can be beneficial to the outflow of gas.
Above cooling gas check valve provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
