Abstract
The utility model discloses a novel pressure release valve which comprises a valve seat and a valve spool. The valve seat is provided with a valve cavity, a valve cavity inlet and a valve cavity outlet, the valve spool is provided with a valve ball and a spring, the valve cavity inlet is positioned at one end of the valve seat, the valve cavity outlet is positioned at the other end of the valve seat, the valve cavity inlet, the valve cavity and the valve cavity outlet are sequentially communicated with one another, the valve spool is positioned in the valve cavity, one end of the spring is abutted onto the valve cavity outlet, the other end of the spring elastically presses the valve ball so that the valve ball is abutted onto the valve cavity inlet, the valve spool is further provided with a piston guide support capable of sliding between a valve cavity inlet side and a valve cavity outlet side in the valve cavity in a reciprocating manner, one end of the guide support is fixedly connected with the valve ball, the other end of the guide support is fixedly connected with the spring, a pressure release channel which penetrates through the guide support is arranged on the guide support, one end of the pressure release channel is communicated with the valve cavity inlet side of the valve cavity, and the other end of the pressure release channel is communicated with the valve cavity outlet side of the valve cavity. The novel pressure release valve has the advantages that owing to the guide support, the contact area of engine oil and the pressure release valve is increased in a pressure release procedure, and accordingly pressure fluctuation can be controlled within a range of 5% and is low.
Description
Technical field
The utility model relates to a kind of Decompression valves, relates in particular to a kind of Novel pressure relief valve.
Background technique
The spool of existing Decompression valves only adopts steel ball to add the structure of spring, because the area of contact of steel ball and machine oil is too little, spring and steel ball come off easily simultaneously, so there is in actual applications the large drawback of pressure surge, it is insufficient to cause engine lubricating oil to supply with, and causes the inordinate wear of motor.
The model utility content
In view of this, technical problem to be solved in the utility model is: provide a kind of pressure surge little Novel pressure relief valve.
In order to achieve the above object, the utility model adopts following technological scheme to realize:
A kind of Novel pressure relief valve, comprise and have valve pocket, the valve seat of valve pocket import and valve pocket outlet, also comprise the spool with valve ball and spring, described valve pocket import is positioned at an end of described valve seat, described valve pocket outlet is positioned at the other end of described valve seat, described valve pocket import, valve pocket and valve pocket outlet are communicated with successively, described spool is positioned at described valve pocket, described spring one end is supported in described valve pocket outlet, the other end suppresses described valve ball and supports in described valve pocket import, wherein, described spool also has can come and go the piston type guiding trestle of slippage between described valve pocket suction side and valve pocket outlet side in described valve pocket, one end and the described valve ball of described guiding trestle are fixedly linked, the other end and described spring are fixedly linked, have the pressure release passage of wearing self on the described guiding trestle, described pressure release passage one end is communicated with the valve pocket suction side of described valve pocket, and the other end is communicated with the valve pocket outlet side of described valve pocket.
As preferably, described guiding trestle has the spring housing socket in an end that connects described spring, and described spring housing is solidly connected on described spring housing socket.
As preferably, described valve seat is the sheathed check ring that is connected with in the valve pocket outlet, and described spring is supported on described check ring.
As preferably, described valve ball and the welding of described guiding trestle are connected.
As preferably, described pressure release passage is positioned at described guiding trestle outer rim mutually on corresponding two side positions.
As shown from the above technical solution, the beneficial effects of the utility model are:
Compared to existing technology, the utility model makes it in pressure leak process by the setting to guiding trestle, the area of contact of machine oil and Decompression valves increases, thereby pressure surge can be controlled in 5%, pressure surge is little, guiding trestle and spring and valve ball are fixedly linked simultaneously, make its linkage structure solid and reliable, and the operation work safety is stable.Particularly, the utility model can be selected according to the main oil gallery pressure demand spring of suitable elasticity parameter by calculating, during work, pressure oil will promote the valve ball retraction when main oil gallery pressure surpasses the spring upper pressure limit, thereby opens the valve pocket import, makes Decompression valves be in open mode, at this moment, pressure oil will flow into valve pocket from the valve pocket import, then releases from the valve pocket outlet via the pressure release passage on the guiding trestle, reaches thus the pressure release purpose.
