Abstract
The invention relates to an oil injection prevention air inlet valve for an electric bus air compressor, which comprises a valve body and a valve seat, wherein the valve body is provided with the valve seat, a piston is arranged in the valve body, the upper end of the piston is provided with a check valve core, the lower end of the check valve core is provided with a check spring, the check spring is arranged on a spring seat, one side of the valve body is connected with a bypass air inlet valve one-way valve through a joint, the other side of the valve body is provided with a stop discharge hole control port, and a hole check ring is arranged between the spring seat. The invention has the advantages of compact structure, firm performance, normally closed air inlet valve, pressure establishment by the bypass one-way valve during starting, piston opening after certain pressure, complete starting of the machine during the period, solving the problem of shake of the check valve core during the original starting, instantaneous closing of the check valve core by the spring force of the check spring at the moment of recoil pressure during the shutdown, and effective prevention of oil mist spraying, thereby solving the two problems of shake and oil injection of the original air inlet valve.
Description
Technical field
The present invention relates to a kind of intake valve, especially a kind of electric bus anti-spraying oil intake valve used for air compressor.
Background technique
Existing bus air compressor gas valve is intake valve open in usual, opens check-valves wicking when air compressor machine variable frequency starting
Gas is produced, when just having started inspiratory capacity deficiency due to machine, non-return valve core will appear shake, when reaching certain inspiratory capacity, non-return valve core
Stablize standard-sized sheet to run well, shuts down by barrel of oil and gas kickback pressure and close non-return valve core, when non-return valve core is by frictional force, resistance
Can close when influence causes mist of oil to spray not in time.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings, provides a kind of compact-sized, reliable performance, can effectively prevent
The only electric bus anti-spraying oil intake valve used for air compressor that mist of oil sprays.
The purpose of the present invention is achieved through the following technical solutions: a kind of electric bus anti-spraying oil intake valve used for air compressor,
Including valve body and valve seat, it is equipped with valve seat in the valve body, piston is equipped in the valve body, is equipped with only in the upper end of the piston
Spool is returned, is equipped with check spring in the lower end of the non-return valve core, the check spring mounts elastically, in the valve body
Side by connector be connected with bypass intake valve check valve, the other side of the valve body be equipped with shut down escape orifice control mouth,
Hole retaining ring is equipped between the spring base and valve body, between the valve body and valve seat, in the non-return valve core and piston
Between, between the piston and valve body be equipped with sealing ring.
A further improvement of the present invention is that: it is connected between the valve body and valve seat by bolt.
The present invention has the advantage that compared with prior art are as follows:
Compact-sized, robust performance, intake valve is normally closed type, establishes pressure by bypass check valve air inlet when starting, when to certain
Piston is opened after pressure, machine starts completely during this period, non-return valve core jitter problem when original starting is solved, when shutting down
Kickback pressure closes non-return valve core by check spring power moment again in a flash, and mist of oil is effectively prevent to spray, thus solve it is former into
The two large problems point of air valve shake and oil spout.
Detailed description of the invention:
Fig. 1 is main view of the invention；
Fig. 2 is side view of the invention；
Fig. 3 is perspective view of the invention；
Figure label: 1- valve body, 2- valve seat, 3- piston, 4- non-return valve core, 5- check spring, 6- spring base, 7- connector, by 8-
Logical intake valve check valve, 9- shut down escape orifice control mouth, the hole 10- retaining ring, 11- sealing ring, 12- bolt.
Specific embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, the implementation
Example for explaining only the invention, is not intended to limit the scope of the present invention..
As Fig. 1-3 shows a kind of specific embodiment of electric bus anti-spraying oil intake valve used for air compressor of the present invention: packet
Valve body 1 and valve seat 2 are included, valve seat 2 is equipped in the valve body 1, piston 3 is equipped in the valve body 1, in the upper end of the piston 3
Equipped with non-return valve core 4, it is equipped with check spring 5 in the lower end of the non-return valve core 4, the check spring 5 is mounted on spring base 6
On, bypass intake valve check valve 8 is connected with by connector 7 in the side of the valve body 1, is equipped in the other side of the valve body 1
Escape orifice control mouth 9 is shut down, it is whether accurate with retaining ring 10 equipped with hole between the spring base 6 and valve body 1, in the valve body 1
Sealing ring 11 is equipped between valve seat 2, between the non-return valve core 4 and piston 3, between the piston 3 and valve body 1；
It is connected between the valve body 1 and valve seat 2 by bolt 12.
Structure of the invention is compact, robust performance, and intake valve is normally closed type, establishes pressure by bypass check valve air inlet when starting
Power opens piston after to certain pressure, and machine starts completely during this period, and non-return valve core shake is asked when solving original starting
Topic, shut down when kickback pressure in a flash again by check spring spring force moment close non-return valve core, effectively prevent mist of oil to spray
Out, to solve the two large problems point of former intake valve shake and oil spout.
The another statement of applicant, implementation method and apparatus structure of the invention that the present invention is explained by the above embodiments,
But the invention is not limited to above embodiment, that is, do not mean that the present invention must rely on the above method and structure could be real
It applies.It should be clear to those skilled in the art, any improvement in the present invention, to implementation method selected by the present invention etc.
