The method of rotary type four-way reversal valve and the fluid switching of sealing.
Background technology
The switching of the different modes such as refrigeration, heating and the defrosting of air conditioning for automobiles heat pump system is commutated by threeway, four-way
Valve is completed, but existing reversal valve be easy during automobile is advanced to be easy to be given a shock cause structural failure, it is stuck or
Phenomena such as leakage.In order to which the commutation function of reversal valve is better achieved, rotary type four-way reversal valve may be used to realize.Rotation
Rotatable four-way reversing valve generally uses motor-driven form, reliability high.But since valve switches torque in sealed states
Greatly, according to directly driving, abrasion will become extremely serious, need heavy-duty motor, to improve cost.It is existing at present
First to promote the valve arrangement that commutates again complicated, it is of high cost, be only applicable to major valve.It is suitable for air conditioning for automobiles etc. to develop
Valve used in mini-system needs one kind simple in structure, and reliability is high and can reduce the machine for wearing and prolonging the service life
Structure.

Using the rotary type four-way reversal valve of special seal.
The technical solution adopted in the present invention is：It is a kind of using double clamp structure and using special seal rotary four
Logical reversal valve is commutated by four-way change valve (1), lower plate lid (2), sealing ring (3), upper plate lid (4), screw (5), four-way
Valve core (6) forms.It is driveed on four-way change valve four direction there are four hole, by the rotation of four-way reversing valve spool Lai real
The switching of existing runner.Sealing ring is used for realizing the rotatory sealing between four-way valve core and valve body.Lower plate lid is fixed by screw
On valve body, sealing ring is positioned, upper plate lid is in contact with spool, is positioned to spool.
The four-way reversing valve is that porose valve body and a pair of selenodont spool composition are opened in a four sides, can pass through valve
Core rotates to realize the switching of runner.
Rotatory sealing can be realized between the valve body and spool of the four-way reversing valve with sealing ring.
The upper and lower plate lid is provided with eight holes corresponding with valve body, can be respectively intended to fixed seal ring and rotary valve
Core.
Sealing ring uses a special construction, the specific sealing ring to be formed by limiting end and deformable lower bottom part；
Deformable lower bottom part and limit end are made of elastic material；Deformable lower bottom part and positive stop end are one
