Abstract
The utility model provides an air compressor machine air -vent valve belongs to mechanical technical field. It has solved current air -vent valve in the use, and warping appears in rubber pad in the valve easily, has restricted the life's of air -vent valve problem. This air compressor machine air -vent valve includes the valve body, the inside cavity for being linked together of valve body, and the inside center of valve body is provided with reset spring, and reset spring's lower extreme supports to lean on and is provided with the rubber pad in valve body inside upper end, and rubber pad one end protruding and stretched into and forms the fixed block in the reset spring downwards, and fixed block outer lane parcel has a copper spare, and reset spring and rubber pad are fixed in the valve body through the silk adjusting nut that turns over in, valve and rubber pad were seted up to the silk adjusting nut center of turning over last plane is to by in valve department. The utility model discloses an improvement to the rubber pad makes its non -deformable have the longer advantage of life.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of pressure regulator valve, particularly to a kind of air compressor machine pressure regulator valve.
Background technology
Pressure regulator valve is also called control valve, and the pressure regulator valve principle of compressed air system is roughly the same, and this pressure regulator valve could also say that pressure-reducing valve or constant pressure valve.Decompression constant voltage principle is: high-pressure medium is charged in a relatively large chamber realize decompression by an aperture, actually by captured area decompression, it is manually set pressure in valve and control to adjust screw rod by diaphragm, the size that adjusting screw rod control airflow hole stimulates the menstrual flow, as long as so giving a fixing pressure, so pressure of outlet plenum will be equal to this pressure always, and this is thought that given pressure can have spring or source of the gas or hydraulic power source to provide, regulates setting with adjusting screw rod.In use, the rubber blanket in valve easily occurs deformation under the repeated action of spring and adjusting screw rod to tradition pressure regulator valve, limits the service life of pressure regulator valve.
Content of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, and in providing a kind of valve, rubber blanket is unlikely to deform, service life longer air compressor machine pressure regulator valve.
The purpose of this utility model can be realized by following technical proposal: a kind of air compressor machine pressure regulator valve, including valve body, described valve inner is the cavity being connected, described valve inner is provided centrally with back-moving spring, the lower end of described back-moving spring is resisted against valve inner upper end and is provided with rubber blanket, it is characterized in that, described rubber blanket one end is downwardly convex and stretches into formation fixed block in back-moving spring, described fixed block outer ring is enclosed with copper piece, described back-moving spring and rubber blanket are fixed in valve body by anti-silk adjusting nut, described anti-silk adjusting nut center offer valve and rubber blanket on flat against at valve.
The benefit of this air compressor machine pressure regulator valve is, rubber blanket one end is downwardly convex and stretches into and forms fixed block in back-moving spring, makes rubber blanket more firm with the connection of back-moving spring, and is enclosed with copper piece in fixed block outer ring, makes that the structure of rubber blanket is firmer to be unlikely to deform.
In above-mentioned a kind of air compressor machine pressure regulator valve, described anti-silk adjusting nut is upwards disposed with air blowing piston, pressure spring and adjusting screw rod, and is installed on valve inner by hexagonal valve gap.
In above-mentioned a kind of air compressor machine pressure regulator valve, described back-moving spring is circular platform type structure and lower surface is more than upper surface.The design of this structure makes being more firmly mounted of the back-moving spring relative to traditional round column type for the back-moving spring, and pressure regulator valve is more accurate during pressure regulation.
Compared with prior art, this air compressor machine pressure regulator valve by making it be unlikely to deform to have longer advantage in service life to the improvement of rubber blanket.

Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.
As shown in Figure 1, this air compressor machine pressure regulator valve includes valve body 1, the internal cavity 2 for being connected of valve body 1, valve body 1 inside center is provided with back-moving spring 3, the lower end of back-moving spring 3 is resisted against valve body 1 inner upper end and is provided with rubber blanket 4, rubber blanket 4 one end is downwardly convex and stretches into formation fixed block 5 in back-moving spring 3, fixed block 5 outer ring is enclosed with copper piece 6, back-moving spring 3 and rubber blanket 4 are fixed in valve body 1 by anti-silk adjusting nut 7, anti-silk adjusting nut 7 center offer valve 8 and rubber blanket 4 on flat against at valve 8.
Describing in detail further, anti-silk adjusting nut 7 is upwards disposed with air blowing piston the 9th, pressure spring 10 and adjusting screw rod 11, and it is internal to be installed on valve body 1 by hexagonal valve gap 12.
Describing in detail further, back-moving spring 3 is circular platform type structure and lower surface is more than upper surface.
Specific embodiment described herein is only explanation for example to the utility model spirit.Described specific embodiment can be made various modification or supplements or use similar mode to substitute by the utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
It although more employing valve body the 1st, cavity the 2nd, back-moving spring the 3rd, rubber blanket the 4th, fixed block the 5th, copper piece the 6th, anti-silk adjusting nut the 7th, valve the 8th, air blowing piston the 9th, pressure spring the 10th, adjusting screw rod the 11st, the terms such as hexagonal valve gap 12 herein, but is not precluded from using the possibility of other terms.These terms are used to be only used to describe and explain essence of the present utility model more easily；It is all contrary with the utility model spirit for being construed as any additional restriction.
