Abstract
The invention discloses a high-reliability pressure regulator, which comprises an adjusting screw, a spring base, a spring, a membrane, a valve tray and a valve body, wherein the tension of the spring is changed through the adjusting screw so that a gasoline pressure adjusting value of the pressure regulator can be regulated. The gasoline pressure changes and vibration are enabled through the membrane so that the gasoline pressure is stabilized at a constant value. Shaking and unstable idle speed of the engine are avoided when oil pressure of an automobile is too low, and the problems that the road driving force is not enough and the engine is not easily started after being shut down are solved.
Description
Technical field
The present invention relates to a kind of highly reliable pressure regulator.
Background technique
When the oil pressure of automobile is crossed when low; Cause unstable idle speed easily, motor is shaken, road driving problem such as be short of power; Sometimes even after flame-out stop a meeting with regard to bad startup; Brought a lot of inconvenience to daily life like this, this just need a kind of highly reliable pressure regulator with the motor that guarantees automobile under various operating modes, gasoline pressure all in the scope of regulation.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of simple in structure, reliable and stable in order to solve the deficiency of existing technology, and can realize changing the pressure regulator of pressure regulated value through adjusting screw.
Technological scheme: in order to realize above purpose, a kind of highly reliable pressure regulator of the present invention, it comprises adjusting screw, spring seat; Spring, diaphragm, valve pallet and valve body, described adjusting screw; Spring seat, spring, diaphragm links to each other with the valve pallet successively, and described valve pallet is provided with valve body.
Described adjusting screw, spring seat, spring, diaphragm and valve pallet are positioned on the same axis.
Beneficial effect: a kind of highly reliable pressure regulator provided by the invention, through the tension force of adjusting screw change spring, can adjust the gasoline pressure regulated value of pressure regulator; Make gasoline variation in pressure vibration through diaphragm, the gasoline pressure stability at a steady state value, has been prevented that automobile from crossing when low at oil pressure, motor is shaken and unstable idle speed, and has solved the problem that road driving is short of power and is not easy to start after flame-out with motor.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
Be illustrated in figure 1 as a kind of highly reliable pressure regulator of the present invention, it comprises adjusting screw 1, spring seat 2, spring 3; Diaphragm 4, valve pallet 5 and valve body 6, described adjusting screw 1, spring seat 2; Spring 3, diaphragm 4 links to each other with valve pallet 5 successively, and described valve pallet 5 is provided with valve body 6.
Described adjusting screw 1, spring seat 2, spring 3, diaphragm 4 is positioned on the same axis with valve pallet 5.
When gasoline pressure surpassed setting, gasoline pressure will promote to move on the diaphragm 4 and valve body 6 is opened, and part gasoline just flows back to petrol tank through valve body 6, and pressure is reduced; When gasoline pressure was lower than the fixed pressure of bar, the spring force of spring 3 made diaphragm 4 according to the vibration of gasoline variation in pressure, with the gasoline pressure stability at steady state value.
Promote spring seat 2 through adjusting screw 1 and move down, thereby change the tension force of spring 3, can adjust the gasoline pressure regulated value of pressure regulator.
A kind of highly reliable pressure regulator provided by the invention through the tension force of adjusting screw 1 change spring 2, can be adjusted the gasoline pressure regulated value of pressure regulator; Make gasoline variation in pressure vibration through diaphragm 2, the gasoline pressure stability at a steady state value, has been prevented that automobile from crossing when low at oil pressure, motor is shaken and unstable idle speed, and has solved the problem that road driving is short of power and is not easy to start after flame-out with motor.
Above-mentioned embodiment only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit is made according to the present invention or modification all should be encompassed within protection scope of the present invention.
