Abstract
The utility model discloses a novel sealing device of oil tank, including oil tank and pump seat, the fuel tank port of oil tank is equipped with O type circle with the butt joint department of pump seat excircle, the lateral surface of O type circle and the lateral surface of the butt joint department of oil tank fuel tank port and pump seat excircle are equipped with the sealing washer, the sealing washer is T shape cover tube seal structure, the sealing washer cramps the surface of pump seat excircle and hugs closely the pump seat. The utility model discloses a sealing washer and O type circle twice seal structure of T shape cover tube-like seal structure has solved the tradition and has only adopted the sealed fuel tank port that causes of O type circle to produce because of the welding reason and warp messenger O type circle inhomogeneous production distortion of atress when the installation, makes sealed inefficacy and the phenomenon of fluid seepage appears, has improved the sealed reliability of oil tank, has reduced the maintenance cost, has guaranteed the life of product.
Description
Technical Field
The utility model belongs to the technical field of the oil tank is sealed, concretely relates to novel sealing device of oil tank.
Background
The sealing between the valve block and the oil tank in the traditional hydraulic power unit mostly adopts O-shaped rings, and the O-shaped rings are not uniformly stressed and distorted when being installed due to the deformation of the oil tank port caused by welding, so that the sealing is failed and the oil leakage is caused.
In order to solve the problem of sealing oil leakage between a pump seat and an oil tank, a novel oil tank sealing device which adopts a sealing piece and an O-shaped ring sealing structure to seal the pump seat and the oil tank, improves the reliability of oil tank sealing and reduces the maintenance cost is provided to solve the problem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel sealing device of oil tank to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel sealing device of oil tank, includes oil tank and pump seat, the fuel tank port of oil tank is equipped with O type circle with the butt joint department of pump seat excircle, the lateral surface of O type circle and the lateral surface of the butt joint department of oil tank fuel tank port and pump seat excircle are equipped with the sealing washer.
The oil tank and pump seat connecting structure has the advantages that the sealing ring and the O-shaped ring are adopted to seal the connecting part of the oil tank and the pump seat, the reliability of oil tank sealing is improved, the maintenance cost is reduced, and the service life of a product is ensured.
Preferably, the sealing ring is a T-shaped sleeve-shaped sealing structure.
This setting utilizes the sealing washer of T shape cover tube-like seal structure for when the sealing washer seals, can cramp the surface of pump seat excircle and hug closely the pump seat, increase sealed effect.
Preferably, the sealing ring hoops the excircle of the pump seat and is tightly attached to the surface of the pump seat.
The utility model discloses a technological effect and advantage: this novel sealing device of oil tank, it is sealed only to adopt O type circle to seal between valve piece and the oil tank among the prior art hydraulic power unit, compensate sealed design, adopt T shape cover tube seal structure's sealing washer and O type circle twice seal structure, solved the tradition and only adopted the sealed fuel tank port that causes of O type circle to produce because of the welding reason and warp and make the inhomogeneous production distortion of O type circle atress when the installation, make sealed inefficacy and the phenomenon of fluid seepage appears, the sealed reliability of oil tank has been improved, the maintenance cost is reduced, the service life of product has been guaranteed.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. an oil tank; 2. a pump mount; 3. an O-shaped ring; 4. and (5) sealing rings.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a novel sealing device of oil tank as shown in figure 1, including oil tank 1 and pump seat 2, the fuel tank port of oil tank 1 is equipped with O type circle 3 with the butt joint department of 2 excircles of pump seat, the lateral surface of O type circle 3 and the lateral surface of the butt joint department of 1 fuel tank port of oil tank and 2 excircles of pump seat are equipped with sealing washer 4.
Specifically, the sealing ring 4 is a T-shaped sleeve-shaped sealing structure.
Specifically, the seal ring 4 hoops the outer circle of the pump base 2 and is tightly attached to the surface of the pump base 2.
The novel oil tank sealing device adopts the O-shaped ring 3 for sealing between a valve block and an oil tank in a hydraulic power unit in the prior art, carries out compensation sealing design, adopts the sealing ring 4 and the O-shaped ring 3 with the T-shaped sleeve-shaped sealing structure, solves the problem that the O-shaped ring 3 is unevenly stressed and distorted during the installation due to the deformation of an oil tank port caused by the sealing of the O-shaped ring 3 in the prior art caused by the welding, leads the sealing failure to cause the phenomenon of oil leakage, improves the reliability of the oil tank sealing, reduces the maintenance cost, ensures the service life of a product, and when in use, the damage to the sealing ring 4 of the oil tank port and the inner surface of the oil tank port is checked before the installation, the sealing ring 4 of the oil tank port tightly hoops the outer circle of a pump seat 2 and tightly clings to the surface of the pump seat 2 during the installation, the installation, checking whether the oil tank opening leaks or not.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
