Abstract
The utility model discloses an overflow valve for a lubricating oil pump, wherein a valve core is arranged in a valve body, the valve core is connected with a plunger, and a spring is sleeved outside the plunger; the valve body comprises a body, a large through cavity and a small through cavity which penetrate through the body are formed in the body, and the large through cavity and the small through cavity are communicated with each other; an oil discharge port communicated with the small through cavity is formed in the valve body; the overflow valve nut is arranged at the port of the large through cavity, so that a split structure in the product in the prior art is improved, leakage points are reduced, and stacking parts are also reduced.
Description
Technical Field
The utility model relates to an overflow valve for lubricating oil pump.
Background
The overflow valve for the lubricating oil pump in the market at present has a plurality of spare parts in the assembling process, leads to the sealing washer increase in quantity, and then the leak point increases, and the later stage is used and has very big defect, remains to improve, so this applicant provides an overflow valve for the lubricating oil pump of improvement just so, reduces stack spare part and corresponding leak point, does benefit to long-term development.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a lubricating oil pump is with overflow valve reduces storehouse spare part and corresponding leakage point, and the whole assembly is simple, and the processing cost reduces.
In order to achieve the above purpose, the technical scheme of the utility model is that:
the overflow valve for the lubricating oil pump comprises a valve body and is characterized in that: a valve core is arranged in the valve body and connected with a plunger, and a spring is sleeved outside the plunger; the valve body comprises a body, a large through cavity and a small through cavity which penetrate through the body are formed in the body, and the large through cavity and the small through cavity are communicated with each other; an oil discharge port communicated with the small through cavity is formed in the valve body; and an overflow valve nut is arranged at the port of the large through cavity.
The utility model is further optimized, and the plunger is provided with an annular buffer groove; the annular buffer groove is close to the overflow valve nut.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses the valve body is overall structure, and convenient nimble in the course of working has improved the split type structure among the prior art product like this, has reduced the leakage point, also reduces storehouse spare part. In addition, the whole assembly of the structure is simplified, the processing is convenient, the product is not easy to deform and break, the integral structural strength is greatly improved, and the long-term development is facilitated.
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
