Description

A kind of bleeder valve
Technical field
The present invention relates to a kind of bleeder valve.
Background technology
At present, valve arrangement of releasing is off-load valve element, damping valve element connects into dumbbell type entirety by bolt, nut, guide pillar Valve element, rubber packing material is installed on damping valve element, and encapsulant fatigue damage, encapsulant just occur after frequent movement Valve element and the very stiff and demanding shock of valve body are damped after damage, nut loosening, bolt fracture, damping valve element abrasion condition occurs, this three Kind of situation can all cause to release valve inlet compressed air leakage to bleeder valve control mouth side, so as to have influence on air inlet valve body Normal work.
The content of the invention
The invention aims to overcome the shortcomings of the above, there is provided a kind of good airproof performance, long service life, working stability Bleeder valve.
The purpose of the present invention is achieved through the following technical solutions：A kind of bleeder valve, including valve body, are provided with valve body and unload Lotus valve element, bonnet is provided with the side of valve body, and control mouth is provided with the opposite side of valve body, and outlet is provided with the lower end of valve body, One end of off-load valve element is cased with damping valve element, and spring is provided between damping valve element and bonnet, entrance is provided with bonnet, in off-load Sealing ring is provided between valve element and control mouth.
The present invention have the advantage that compared with prior art for：Off-load valve element and damping valve element split-type structural are employed, Damping valve element is changed to macromolecular material by original metal material, eliminates rubber packing material, advantage one：The macromolecular material longevity Order considerably beyond rubber packing material, advantage two：Without hole in the middle of newly-designed bleeder valve off-load valve element, so valve inlet of releasing Compressed air because of the leakage of damping valve element or can not possibly damage, and drain to the control mouth side of bleeder valve, would not also have influence on The normal work of air inlet valve body, reliability obtains big lifting.
Brief description of the drawings：
Fig. 1 is structural representation of the invention；
Label in figure：1- valve bodies, 2- off-loads valve element, 3- bonnets, 4- damping valve element, 5- springs, 6- entrances, 7- control mouths, 8- sealing rings, 9- outlets.
Specific embodiment：
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should Embodiment is only used for explaining the present invention, is not intended to limit the scope of the present invention..
A kind of a kind of implementation method of bleeder valve of the invention is shown such as Fig. 1：Including valve body 1, off-load is provided with valve body 1 Valve element 2, bonnet 3 is provided with the side of valve body 1, and control mouth 7 is provided with the opposite side of valve body 1, and outlet is provided with the lower end of valve body 1 9, it is cased with damping valve element 4 in one end of off-load valve element 2, spring 5 is provided between damping valve element 4 and bonnet 3, it is provided with bonnet 3 Entrance 6, is provided with sealing ring 8 between off-load valve element 2 and control mouth 7, and sealing ring 8 is provided between bonnet 3 and valve body 1.
Present invention employs off-load valve element and damping valve element split-type structural, damping valve element is changed to by original metal material Macromolecular material, eliminates rubber packing material, advantage one：The macromolecular material life-span is considerably beyond rubber packing material, advantage Two：Without hole in the middle of newly-designed bleeder valve off-load valve element, so the compressed air of valve inlet of releasing can not possibly be because of orifice valve Core is leaked or damaged, and drains to the control mouth side of bleeder valve, would not also have influence on the normal work of air inlet valve body, reliability Obtain big lifting.
