Abstract
The utility model relates to an air -vent valve especially relates to an oil pump air -vent valve. Including valve body, steel ball, spring, the adjusting screw who connects gradually, adjusting screw twist the inboard one end of valve body, with steel ball and spring card in the valve body, valve body length be 4 6 centimetre, the biggest atress of spring is 5Kg, and the valve body top is provided with backward flow hole, the other end and is provided with the inlet port, the inlet port in the scarf joint advance the oil pipe way. The more traditional air -vent valve of the volume of this air -vent valve is big, and spring bearable pressure is bigger, and is more stable, reaches the purpose of stabilizing the pressure regulating.
Description
【Technical field】
This utility model is related to pressure regulator valve, more particularly to a kind of oil pump pressure regulator valve.
【Background technology】
Traditional pressure regulator valve is little due to valve volume, and, typically at 2-3 centimetre, the pressure that spring can bear is little, easily for length
The springing in the valve body, so as to cause steel ball also to be beated in valve body so that pressure transient, the work of strong influence pressure regulator valve
Make.It is therefore desirable to providing a kind of oil pump pressure regulator valve of energy stable regulation pressure.
【The content of the invention】
This utility model aim to solve the problem that the problems referred to above and provide it is a kind of can stable voltage oil pump pressure regulator valve.
For achieving the above object, a kind of oil pump pressure regulator valve of the present utility model, including the valve body 10, steel ball being sequentially connected
20th, spring 30, voltage regulation screw 40, described voltage regulation screw 40 are screwed into the one end on the inside of valve body 10, and steel ball 20 and spring 30 are blocked
In valve body 10, described 10 length of valve body is 4-6 centimetre, and the maximum weighted of spring 30 is 5Kg, is provided with back above valve body 10
The discharge orifice 11, other end is provided with fuel feed hole 12, and described fuel feed hole 12 is embedded to tap into oil-piping 80.
Further, sealing ring 50, described sealing ring 50 and valve body 10 is additionally provided with after described voltage regulation screw 40
Between be tightly connected.
Further, shockproof thimble 60 is provided with after described sealing ring 50, connection locking after described shockproof thimble 60
Nut 70, described locking nut 70 are connected with the locking of valve body 10.
Contribution of the present utility model is, there is provided a kind of pressure adjusts stable oil pump pressure regulator valve, the volume of the pressure regulator valve
Big compared with traditional pressure regulator valve, spring allowable stress is bigger, more stable, reaches the purpose of stable voltage.
【Description of the drawings】
Fig. 1 is detonation configuration figure of the present utility model.
【Specific embodiment】
The following example is explained further and supplements to of the present utility model, does not constitute any limit to this utility model
System.
Embodiment 1
As shown in figure 1, the valve body 10 that a kind of oil pump pressure regulator valve includes being sequentially connected in the present embodiment, steel ball 20, spring 30,
Voltage regulation screw 40, described voltage regulation screw 40 are screwed into the one end on the inside of valve body 10, and steel ball 20 and spring 30 are stuck in valve body 10,
Described 10 length of valve body is 4-6 centimetre, and the maximum weighted of spring 30 is 5Kg, is provided with return port 11, another above valve body 10
End is provided with fuel feed hole 12, and described fuel feed hole 12 is embedded to tap into oil-piping 80.The operation principle of pressure regulator valve is as follows：High-pressure oil passage
A relatively large chamber interior-excess is entered into by an aperture now to reduce pressure, actually by decompression of damming, aperture size is controlled
Steel ball be connected tightness, as long as so to a fixed pressure, then the pressure in fuel pump outlet chamber will be equal to this always
Individual pressure, this thinks that given pressure is exactly spring providing.Fluid oil is entered from fuel feed hole 12 and pushes steel ball 20 open, and oil is entered
To inside valve body 10 from the 11 overflow oil sump tank of return port of valve body 10, adjust the compression stress of spring 30 to promote with set screw 40
Steel ball 20 adjusts size of the oil to 80 end oil pressure of flowline to control the size of oil mass.The body of the pressure regulator valve of the embodiment
Product is big compared with traditional pressure regulator valve, and spring allowable stress is bigger, more stable, reaches the purpose of stable voltage.
Embodiment 2
As shown in figure 1, the voltage regulation screw 40 described in the present embodiment is additionally provided with sealing ring 50, described sealing ring afterwards
It is tightly connected between 50 and valve body 10.In order to ensure oil be discharge from fuel feed hole 12 rather than by sealing ring 50 and valve body 10 it
Between gap discharge, will be tightly connected between sealing ring 50 and valve body 10, it is ensured that pressure regulation quality.
Further, shockproof thimble 60 is provided with after described sealing ring 50, connection locking after described shockproof thimble 60
Nut 70, described locking nut 70 are connected with the locking of valve body 10.
Embodiment 3
As shown in figure 1, shockproof thimble 60 is provided with after sealing ring 50 described in the present embodiment, after described shockproof thimble 60
Connection locking nut 70, described locking nut 70 are connected with the locking of valve body 10.In order that the stable fixation of 40 energy of set screw
In valve body 10, shockproof thimble 60 is provided with, prevents 40 jumping effect of set screw from rocking to steel ball 20.Tightening nut 70 prevents
Eject from valve body 10 after 40 long-time use of set screw.
Although being disclosed to this utility model by above example, protection domain of the present utility model not office
It is limited to this, under conditions of conceiving without departing from this utility model, each component is done to more than deformation, replacement etc. will fall into this
In the right of utility model.
