Abstract
The utility model relates to a structure of reversing valve. Including valve body and valve gap, be equipped with the working chamber between valve body and the valve gap, be equipped with the import of first import and second on the valve gap, the valve gap is equipped with first valve port and second valve port with the working chamber contact jaw, first import with first valve port intercommunication, second import with second valve port intercommunication, be equipped with first export on the valve body, first export with the working chamber intercommunication, be equipped with the pivot on the valve body, the pivot is located axial region in the working chamber is equipped with the valve block. The valve block comprises nonrust steel pole and sheet rubber, and the valve gap is equipped with bulge loop, the effectual leakproofness of guaranteeing the switching -over valve with the valve block contact position, it is sealed because of the flexible plane of adopting rubber materials simultaneously, can not leak or block up because of solid particle inserts sealed face because of wearing and tearing cause.
Description
Technical field
This utility model is related to valve field and in particular to a kind of structure of reversing valve.
Background technology
Current reversal valve is to be performed relative motion in valve body in the hole using valve element, so that oil circuit is switched on or off and change liquid
Flow direction.Between valve element and valve body hole, fit clearance is little, easily blocks；Fit clearance is big, the sealing surface that can not form
Easily leak.Thus there is very high requirement to the accuracy of manufacture of valve element, valve body hole, increased manufacture difficulty and be manufactured into
This.
Utility model content
The problem existing for prior art, the purpose of this utility model is to propose a kind of technical side of structure of reversing valve
Case.
A kind of described structure of reversing valve it is characterised in that: include valve body and valve gap, between valve body and valve gap, be provided with work
Chamber, valve gap is provided with the first import and the second import, and valve gap and working chamber contact jaw are provided with the first valve port and the second valve port；Described
First import is connected with described first valve port, and described second import is connected with described second valve port；Described valve body is provided with first
Outlet, first outlet is connected with described working chamber；Described valve body is provided with rotating shaft, and the axle portion that rotating shaft is located at described work intracavity sets
There is valve block, the first sheet rubber that described valve block by stainless steel, is arranged on stainless steel two ends and the second sheet rubber are constituted, first
Sheet rubber is engaged with the first valve port, and the second sheet rubber is engaged with the second valve port；Described valve gap and described first rubber
Piece contact position and valve gap are equipped with bulge loop with described second sheet rubber contact position.
A kind of described structure of reversing valve it is characterised in that: described first sheet rubber contact described bulge loop one side to the left
It is obliquely installed.
A kind of described structure of reversing valve it is characterised in that: described second sheet rubber contact described bulge loop one side to the right
It is obliquely installed.
A kind of described structure of reversing valve it is characterised in that: be provided with sealing ring between described valve body and described valve gap.
The beneficial effects of the utility model: valve block is made up of stainless steel and sheet rubber, valve gap is set with valve block contact position
There is bulge loop, be effectively guaranteed the sealing of reversal valve；Simultaneously because of the flexible flat sealing using elastomeric material, will not be because of abrasion
Cause to leak or block because solid particle inserts sealing surface.
Brief description

Specific embodiment
With reference to Figure of description, this utility model is elaborated.
This utility model includes valve body 2 and valve gap 1, is provided with working chamber 8 between valve body 2 and valve gap 1, and valve gap 1 is provided with
One import a and the second import b, valve gap 1 and working chamber 8 contact jaw are provided with the first valve port c and the second valve port d；First import a and
One valve port c connection, the second import b is connected with the second valve port d；Valve body 2 is provided with first outlet e, first outlet e and working chamber 8
Connection；Valve body 2 is provided with rotating shaft 6, rotating shaft 6 be located at working chamber 8 in axle portion be provided with valve block, valve block by stainless steel, be arranged on
First sheet rubber 3 at stainless steel two ends and the second sheet rubber 5 are constituted, and the first sheet rubber 3 is engaged with the first valve port c, the
Two sheet rubbers 5 are engaged with the second valve port d, using elastomeric material flexible flat sealing, will not because abrasion cause leakage or
Block because solid particle inserts sealing surface；During use, rotating shaft closes one of two valve ports valve port.
Valve gap 1 and the first sheet rubber 3 contact position, valve gap 1 and the second sheet rubber 5 contact position are equipped with bulge loop 7, effectively
The sealing that ensure that reversal valve.The one side that first sheet rubber 3 contacts bulge loop is tilted to the left setting, can make the first sheet rubber 3
Preferably seal up the first valve port c；The one side that second sheet rubber 5 contacts described bulge loop is tilted to the right setting, can make the second rubber
Film 5 preferably seals up the second valve port d.It is provided with sealing ring 4 between valve body 2 and valve gap 1, prevent liquid from valve body 2 and valve gap 1
Between gap in leak.
