Description
Technical field
The utility model relates to a kind of devices of pump housing sealing water a kind of in pump equipment more particularly to water pump.
Background technique
A kind of sealing device of pump body is a kind of device for preventing the water outflow pump housing, has in field of sealing technology and answers extensively
With.In a device, the influence that the sealing device of pump body is stable to the performance of water pump and reduction is to ambient enviroment is played to pass
Effect, pump cover and the sealing surface of pump seat its special construction cooperate the assembly of copper sealing ring to be that pump body can be good at sealing again
Firmly water provides safeguard, and reduces the risk of the liquid outflow in pump body.For this purpose, a kind of ad hoc sealing dress for counting pump body
It sets, extends the service life of water pump.
Summary of the invention
To achieve the above object, technical solution provided by the utility model is: a kind of sealing device of pump body, it
It is made of the special sealing surface of pump cover, the special sealing surface of pump seat and copper sealing ring.The special sealing surface and pump of the pump cover
The special sealing surface structure of seat is identical, and two sealing surfaces are that mirror image cooperates when assembly；The structure of special sealing surface is three-dimensional right angle
Triangle, for inner ring perpendicular to plane, outer ring is then inclined-plane；It is the thin ring of sharp at the top of special sealing surface；Pump cover and pump seat
Special sealing surface diameter is identical, and two special sealing surfaces are mirror image when assembling；Special sealing surface material is that hardness is greater than copper
The material of sealing ring processed；Copper sealing ring is the copper ring of the smooth flat pattern in two sides；Copper sealing ring is assemblied in pump
When between the special sealing surface of lid and the special sealing surface of pump seat, the copper among two sealing surfaces is squeezed from pump cover and pump seat both sides
Sealing ring processed, since the top of special sealing surface can be embedded in copper sealing ring, so two special sealing surfaces and copper sealing ring
Between will form the faces of two close contacts, to have the function that seal gap between pump cover and pump seat;
The sealing device of the pump body, the structure of special sealing surface are three-dimensional right angled triangles, inner ring perpendicular to
Plane, outer ring are inclined-planes;
The sealing device of the pump body is the thin ring of sharp at the top of special sealing surface;
The sealing device of the pump body, copper sealing ring are the copper ring of the smooth flat pattern in two sides;
The utility model has the advantages that: stability is good, and installation is simple；Copper sealing ring cooperation special sealing surface ensures water pump
Pump cover and pump seat between be in close contact, it is ensured that will not be leaked caused by and the excessively high aging of temperature long because of the time, use spirit
It is living.

Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples, the utility model preferred embodiment are as follows:
Referring to attached drawing 1, attached drawing 2, attached drawing 3, attached drawing 4 and attached drawing 5.A kind of sealing device of pump body described in this example, it is by pumping
Lid 1, pump seat 2 and copper sealing ring 4 form.The sealing surface of the pump cover 1 and pump seat 2 is special structure, and structure is solid
The sealing surface material hardness of right triangular shape, pump cover 1 and pump seat 2 is greater than the hardness of copper sealing ring 4, by copper sealing ring
In the groove of 4 pump covers 1, and copper sealing ring 4 will be placed in right above the special sealing surface of pump cover 1, the special sealing surface of pump seat 2
It is that mirror assembles with the special sealing surface of pump cover 1, the special sealing surface of the special sealing surface of pump seat 2 and pump cover 1 is being just at this time
Two planes for clamping copper sealing ring 4 well are reached by fastening pump cover 1 and pump seat 2 and squeeze copper sealing ring 4, copper sealing
Two grooves can be squeezed out by enclosing 4 both sides, in the groove of the special sealing surface insertion copper sealing ring 4 of pump cover 1 and pump seat 2, be reached
The effect of being in close contact the effect of copper sealing ring 4 to the special sealing surface of pump cover 1 and pump seat 2, forming sealing;
Since the hardness of copper sealing ring 4 is lower than the hardness of 2 sealing surface of pump cover 1 and pump seat, when from pump cover 1 and 2 liang of pump seat
When side squeezes copper sealing ring 4 toward centre, copper sealing ring 4 understands the sealing surface shaped depressions according to pump cover 1 and pump seat 2,
To achieve the effect that fit together perfectly between pump cover 1 and pump seat 2 by the formation of copper sealing ring 4, liquid just can not be from pump cover 1 and pump
It is flowed out between seat 2, achievees the purpose that seal gap between pump cover 1 and pump seat 2;
Example described above is only the preferred embodiments of the utility model, and the implementation model of the utility model is not limited with this
It encloses.Therefore the variation that all shape, principles according to the utility model are done, it should all cover in scope of protection of the utility model.
