Description
Technical Field
The invention relates to the field of oil filters, in particular to a novel mounting structure of a machine filter bypass valve.
Background
The bypass valve used in the oil filter is used for ensuring that when a filter element in the oil filter is blocked, the oil inlet and the oil outlet of the filter reach a certain pressure difference, the bypass valve is opened, and engine oil directly flows into a main lubricating oil duct without filtering, so that the normal lubrication of the whole engine is ensured.
The bypass valve for the oil filter comprises a central tube and a bypass valve end cover, wherein the input end of the central tube is tightly connected with the filter core paper through the bypass valve end cover, an oil inlet is formed in the center of the bypass valve end cover, a valve body seat is arranged in the central tube, an oil outlet is formed in the valve body seat, a through hole for a piston to penetrate is formed in the valve body seat, a spring is sleeved on the piston, and the top of the piston seals the oil inlet in the bypass valve end cover. This solution has the following drawbacks: on one hand, the bypass valve structure is integrated with the filter element, so that the coaxiality, perpendicularity and other form and position tolerances of parts such as a central tube, a bypass valve end cover, a valve body seat and the like are required to be controlled in the processing process, and the processing and production difficulty is high; on the other hand, the filter element is a disposable article, and the bypass valve can only be discarded together when the filter element is replaced at the end of the service life, so that the replacement cost is high.
Disclosure of Invention
The invention aims to provide a novel machine filter bypass valve mounting structure which solves the defects in the prior art, and is detachably connected to a spiral cover of an engine oil filter, so that the novel machine filter bypass valve mounting structure does not need to be discarded together with a filter element; meanwhile, the processing convenience and the maintenance convenience are good; at the same time, it has good working properties.
In order to achieve the aim of the invention, the invention adopts the following technical scheme:
the novel mounting structure of the engine filter bypass valve comprises an engine oil filter spiral cover and a bypass valve arranged on the inner side of the spiral cover, wherein the spiral cover comprises at least two connecting parts circumferentially arranged around the axis of the spiral cover; the bypass valve comprises a shell and a bypass assembly, wherein the shell comprises a valve shell and a functional shell arranged below the valve shell, the valve shell is provided with a first valve cavity with a downward opening, a plurality of supporting ridges circumferentially arranged on the wall surface of the first valve cavity at intervals are arranged in the first valve cavity, and the bypass assembly is arranged in the valve shell; the valve shell and the inner wall of the functional shell are combined to form a second valve cavity, and the functional shell is circumferentially provided with a mounting part which corresponds to the connecting part and is detachably connected with the connecting part.
Therefore, the bypass valve is detachably connected to the connecting part on the spiral cover through the mounting part, and when the spiral cover, the bypass valve and the filter element for replacement can be manufactured independently, namely, the processing difficulty of each component is reduced. When in installation, the installation part of the bypass valve is firstly installed in the connection part, and then the filter element is installed and sleeved on the framework type connection column at the outer side of the bypass valve; when the filter element is replaced, the filter element can be directly replaced and discarded, and the bypass valve is still arranged on the spiral cover; when the bypass valve works for a long time and needs maintenance, the installation part and the connecting part can be disconnected, so that the bypass valve is detached for maintenance.
In a preferred aspect of the present invention, the connecting portion includes an open groove provided on one side thereof, and the mounting portion is engaged with the open groove.
Therefore, the mounting part achieves convenient dismounting effect and stable mounting state through the form of the card access opening groove.
Preferably, the mounting portion includes a mounting ridge and an elastic member provided outside the mounting ridge.
The installation ridge is in fan-shaped integral fit with the opening groove, the installed position of the elastic piece is located between the installation ridge and the opening groove, the elastic piece is extruded by the installation ridge and the opening groove to generate certain deformation, and the elastic piece has reaction force to the installation ridge and the opening groove, so that the installation stability of the bypass valve is improved through the resultant force of the reaction forces of the installation part and the connecting part on the whole; on the other hand, at the joint of the mounting part and the connecting part, the elasticity of the connecting part can eliminate the possible gap between the mounting part and the connecting part, so that the connection is stable and difficult to loose.
Preferably, the elastic member is integrally formed with the mounting ridge, and one end of the elastic member is connected to the mounting ridge and extends along a folding line in the direction of the mounting ridge.
Therefore, the processing manufacturability of the elastic piece and the mounting ridge is more convenient, and the fold line of the elastic piece extends to provide elasticity for the elastic piece structurally, so that the elastic piece can be produced by adopting materials with different elastic properties, such as plastics, metals and the like.
Preferably, the housing further comprises a hollow skeleton-type connecting column, and one end of the connecting column is integrally formed on the outer side of the valve housing and extends upwards.
Therefore, the connecting column can play a role in increasing the contact area with the filter element and improving the assembly stability. The skeleton form has good mechanical property and light weight.
Preferably, the side surface of the valve housing is provided with a circumferentially arranged oil through hole.
Therefore, when the bypass valve works, engine oil flows out from the oil through port, rather than directly flows out from the movable opening of the valve body as in the prior art, and the flow property of the engine oil can be better regulated.
As a preferred aspect of the present invention, the bypass assembly includes a valve body, a first spring, a valve ring, and a second spring, where the first spring is sleeved outside the valve body and is disposed in the first valve cavity together, and one end of the first spring abuts against the valve body, and the other end abuts against the supporting ridge; the valve ring is arranged in the second valve cavity in a sealing way, the top surface of the valve ring is abutted against the bottom surface of the valve shell, one end of the second spring is abutted against the lower surface of the valve ring, and the other end of the second spring is abutted against the inner bottom surface of the spiral cover.
Therefore, the valve body is arranged in the first valve cavity in a recoverable manner through the first spring, meanwhile, the valve ring is stopped in the second valve cavity through the second spring, at the moment, the valve body is stopped with the valve ring, when the oil pressure of the filter element is increased due to blockage failure, the valve body is pressed into the first valve cavity after the oil pressure is larger than the elastic force of the first spring, and accordingly an oil passage is opened in the valve body and the valve ring, and the bypass valve works. The elastic force of the second spring is not only used for stopping the valve ring and the valve shell, but also used for stopping the connection part and the mounting part in the vertical direction after the elastic force of the second spring acts on the valve shell, namely the whole bypass valve, so that the stability after the mounting is further improved.
Preferably, the valve ring comprises a transverse ring body, an annular sealing part extending from the end surface of the ring body, a sealing part with a downward surface extending, and an oil through hole arranged in the center of the ring body, wherein the oil through hole is provided with an arc-shaped contact surface.
The valve ring is thereby sealed against the valve housing by the sealing portion, preventing oil from flowing in from the mounting gap.
Preferably, the valve ring end face is provided with a raised sealing ring.
The contact between the valve body end and the arc-shaped contact surface effectively seals engine oil when the oil pressure does not exceed the elastic force of the first spring.
Further, the end part of the valve body is arc-shaped or conical, and the end part of the valve body is in sealing contact with the arc-shaped contact surface.
The invention has the advantages of strong structural integrity, good processing convenience, convenient disassembly and maintenance and good engine oil tightness.
