Abstract
The utility model relates to a valve oil seal static sealing performance detection device, which comprises a cavity body, a cushion plate and screws, wherein an inner cavity, an air port and a ladder, wherein an outer flanging of a framework of a valve oil seal is embedded on the ladder, the valve oil seal is fixedly arranged in the cavity body through the cushion plate via the screws, an air valve guide pipe and an air valve rod are sequentially sleeved in the valve oil seal, and an O-shaped ring is arranged between the outer side wall of the valve oil seal and the inner cavity. When the valve oil seal is arranged on the detection device, medium oil is injected into the cavity body through the air port, the air pressure of an air pumping machine is adjusted to observe whether oil leakage phenomenon occurs in the valve oil seal under corresponding pressure conditions, thereby realizing the purpose of detecting the static sealing performance indexes of products; and the valve oil seal static sealing performance detection device has advantages of simple structure and convenient application.
Description
Technical field
The utility model relates to a kind of pick-up unit of valve oil seal static seal performance.
Background technology
The detection of existing domestic valve oil seal performance, all product can only be loaded onto to the quality of verifying properties of product after engine by engine, but it is exactly in the time that oil leakage phenomenon appears in product that this mode has individual shortcoming, cannot clearly go out at once that leakage of oil appears in product in static seal or product leakage of oil in engine running.Can detect the static seal performance of valve oil seal by this device, thereby effectively confirm the quality of product static seal performance.
Summary of the invention
The purpose of this utility model is to provide a kind of pick-up unit of valve oil seal static seal performance, be intended to verify whether valve oil seal product there will be oil leakage phenomenon under out-of-work state, thereby effectively check out the quality of product static seal performance, and in the time that oil leakage phenomenon appears in product, it is to descend in working order leakage of oil or leakage of oil under halted state that this device can be assisted analytic product leakage of oil.
The utility model, comprise cavity, backing plate and screw, in cavity, be provided with inner chamber, gas port and level rank, the skeleton flanging of valve oil seal is nested on described level rank, backing plate is fixedly mounted on valve oil seal in cavity by screw, in valve oil seal, be set with successively valve guide bushing and valve stem, between valve oil seal lateral wall and inner chamber, be provided with O type circle.
The utility model, after valve oil seal is arranged on to described pick-up unit, Medium Oil injects cavity by gas port, then under corresponding pressure condition, whether there will be oil leakage phenomenon by the barometric observation valve oil seal that regulates pump, thereby realizes the quality of the static seal performance that detects product.And simple in structure, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure, 1, cavity; 2, backing plate; 3, screw; 4, valve stem; 5, valve oil seal; 6, O type circle; 7, valve guide bushing; 8, gas port; 9, inner chamber; 10, level rank; 11, skeleton flanging.
Embodiment
With reference to Fig. 1, a kind of pick-up unit of valve oil seal static seal performance, it is characterized in that: comprise cavity 1, backing plate 2 and screw 3, in cavity 1, be provided with inner chamber 9, gas port 8 and level rank 10, the skeleton flanging 11 of valve oil seal 5 is nested on described level rank 10, backing plate 2 is fixedly mounted on valve oil seal 5 in cavity 1 by screw 3, is set with successively valve guide bushing 7 and valve stem 4 in valve oil seal 5, is provided with O type circle between valve oil seal 5 lateral walls and inner chamber 9.
When measurement, first valve oil seal 5 products are loaded onto to valve guide bushing 7, then valve stem 4 is also passed to valve guide bushing 7 through the lip of product, then O type circle 6 is enclosed within on the outside surface of valve oil seal 5 products, then valve oil seal 5 products are loaded onto to cavity 1, again backing plate 2 is tightened together by screw 3 with cavity 1, then Medium Oil is injected to cavity until fill by gas port 8.Finally the outtake tube of high pressure pump is connected on the gas port 8 of cavity, under corresponding pressure condition, whether there will be oil leakage phenomenon by the barometric observation valve oil seal that regulates pump.The final quality that realizes the static seal performance that detects product.
