Description
Technical field
The present invention relates to filter and pressure valve technical fields more particularly to a kind of pressure for air cleaner
Valve.
Background technology
For filter as a kind of general type filter utility, application range is very extensive, such as oil filtration system, air
Filtering system etc..Existing filter when being particularly applied to circulate environment, causes to recycle when blocking in order to avoid filter core
Channel is blocked, and bypass circulation is designed with.
Existing bypass circulation, have electric signal control valve realize, also have using pressure valve, but these by-passing valves without
One is not complicated, and cannot be filtered to fluid, is had a single function.
Invention content
Technical problems based on background technology, the present invention propose a kind of pressure valve for air cleaner.
A kind of pressure valve for air cleaner proposed by the present invention, including：Cylinder and multilayer elastic pad；Cylinder is two
End is to leading to structure；Multilayer elastic pad is stacked in inner barrel, and each cushion is circumferential to be tightly connected with cylinder inboard wall；Each bullet
Property pad on be equipped with multiple apertures as cushion stretches and widened filter opening, and cushion is under natural conditions, and filter opening is closed.
Preferably, cylinder periphery is equipped with a circle flange face, and multiple through-holes are circumferentially provided on flange face.
Preferably, the side of flange face is covered with gasket.
Preferably, cylinder is made of multistage shell ring, shell ring be both ends to lead to structure, both ends be respectively equipped with match it is interior
Screw thread and external screw thread；Multilayer elastic pad is corresponded with multistage shell ring, and each cushion is mounted on inside corresponding shell ring and is located at
Internal thread inside shell ring is close to externally threaded side.
Preferably, flange face is disposed therein the periphery of a section shell ring.
Preferably, it is equipped with a block baffle in each section of shell ring, baffle is parallel to cushion under natural conditions, and against bullet
Property pad, baffle be equipped with through-hole.
Preferably, cushion uses rubber pad.
A kind of pressure valve for air cleaner proposed by the present invention under normality, passes through cushion and completely cuts off cylinder both ends
Fluid to logical, the pressure difference at only cylinder both ends reaches a certain level, and each cushion is extruded when extending to filter opening and opening
The fluid flowing that could realize cylinder both ends, realizes the break-make by automatic pressure control valve body.
A kind of pressure valve for air cleaner proposed by the present invention, it is simple in structure, it is easily installed and replaces, be applicable in model
It encloses wide；And in the present invention, fluid convection is realized by the filter opening on cushion, is conducive to through filter opening to the pollutant in fluid
It is filtered.

Specific implementation mode
Referring to Fig.1, a kind of pressure valve for air cleaner proposed by the present invention, including：Cylinder 1 and multilayer elastic pad
2.Cylinder 1 is both ends to leading to structure.Multilayer elastic pad 2 is stacked inside cylinder 1, and each cushion 2 is circumferentially and in cylinder 1
Wall is tightly connected.Multiple apertures are equipped on each cushion 2 as cushion 2 stretches and widened filter opening, and cushion 2 is natural
Under state, filter opening is closed.In this way, when the pressure valve works, under normality, the fluid pair at 1 both ends of cylinder is completely cut off by cushion 2
Logical, the pressure difference at only 1 both ends of cylinder reaches a certain level, and each cushion 2 is extruded when extending to filter opening opening could be real
The fluid flowing at existing 1 both ends of cylinder.
In present embodiment, cushion 2 uses rubber pad.
Embodiment 1
In the present embodiment, 1 periphery of cylinder is equipped with a circle flange face 3, and multiple through-holes are circumferentially provided on flange face 3.In this way,
When installation, it can pass through the through-hole on flange face 3 that the pressure valve is fixedly mounted by bolt.
In the present embodiment, the side of flange face 3 is covered with gasket, when being installed with improving cylinder 1,1 periphery of cylinder and week
The leakproofness of closed structure.
Embodiment 2
In the present embodiment, cylinder 1 is made of multistage shell ring 1-1, shell ring 1-1 be both ends to lead to structure, both ends are set respectively
There is the internal thread 5 and external screw thread to match.In this way, adjacent shell ring 1-1 is connect by internal thread 5 with external screw thread fitted seal,
It ensure that the leakproofness docked between shell ring 1-1, and ensure that being readily disassembled for cylinder 1.Multilayer elastic pad 2 and multistage shell ring 1-
1 corresponds, and each cushion 2 is mounted on the internal thread 5 inside corresponding shell ring 1-1 and inside shell ring 1-1 close to outer spiral shell
The side of line 4.In this way, in this implementation, by dismantling shell ring 1-1, single shell ring 1-1 can be replaced, to reduce entirely
The risk that pressure valve is scrapped, reduces cost.
Embodiment 3
The present embodiment is combined embodiment 2 and embodiment 3, specifically, in the present embodiment, the setting of flange face 3 is existed
The periphery of wherein one section shell ring 1-1.
Embodiment 4
In embodiment 3, a block baffle 6 is equipped in each section of shell ring 1-1, baffle 6 is parallel to cushion under natural conditions
2, and against cushion.Baffle 6 is equipped with through-hole.In this way, by the way that baffle 6 is arranged, cushion 2 can be prevented towards 6 side of baffle
Extension, so that cushion 2 is extended only towards side so that the pressure valve can only one-way conduction.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
