Sealing ring, between the inwall being arranged on described shear pin and described radial direction through hole, for being connected and sealed to described shear pin and described bleeder main body;
Pressure cap, is fixedly connected with by screw thread with described radial direction through hole, for being fixed in described radial direction through hole by one end of described shear pin;
Wherein, when the other end of described shear pin is cut off, the inner chamber of described bleeder main body is by the through hole of described hollow blind hole and described pressure cap and ft connection.
Optionally, described sealing ring is specially O RunddichtringO.
Optionally, be provided with a boss in described radial direction through hole, one end of described shear pin and described boss are sealed by described sealing ring and are connected.
Above-mentioned one or more technical scheme in the embodiment of the present application, at least has following technique effect:
The embodiment of the present application provides a kind of hammering oil discharger comprising bleeder main body, sealing ring, shear pin and pressure cap, be fixedly connected with by the screw thread of pressure cap with the radial direction through hole in bleeder main body, shear pin is fixed in bleeder main body, avoids shear pin to loosen and cause bleeder inefficacy; By sealing ring, bleeder main body and shear pin are sealed, enhance reliability and the resistance to corrosion of sealing, solve the technical problem that bleeder in prior art easily lost efficacy, extend the application life of bleeder.
Accompanying drawing explanation
The structural representation of a kind of hammering oil discharger that Fig. 1 provides for the embodiment of the present application;
The draining schematic diagram of a kind of hammering oil discharger that Fig. 2 provides for the embodiment of the present application.
Detailed description of the invention
In the technical scheme that the embodiment of the present application provides, by changing the connected mode between shear pin and the radial direction through hole of bleeder main body, and the sealing means between bleeder main body and shear pin, solve the technical problem that bleeder in prior art easily lost efficacy, realize the prolongation to bleeder application life.
Below in conjunction with accompanying drawing, the main of the embodiment of the present application technical scheme is realized principle, detailed description of the invention and be explained in detail the beneficial effect that should be able to reach.
Embodiment
Please refer to Fig. 1, the embodiment of the present application provides a kind of hammering oil discharger, and described bleeder comprises:
Bleeder main body 1, comprises a radial direction through hole;
Shear pin 3, comprises a hollow blind hole, and one end of described shear pin 3 is arranged in described radial direction through hole, and the other end of described shear pin 3 is arranged on the inner chamber of described bleeder main body 1 through described radial direction through hole;
Sealing ring 2, is arranged between described shear pin 3 and the inwall of described radial direction through hole, for being connected and sealed to described shear pin 3 and described bleeder main body 1;
Pressure cap 4, is fixedly connected with by screw thread with described radial direction through hole, for being fixed in described radial direction through hole by one end of described shear pin 3;
Wherein, when the other end of described shear pin 3 is cut off, the inner chamber of described bleeder main body 1 is by the through hole of described hollow blind hole and described pressure cap 4 and ft connection.
Concrete, in order to strengthen the sealing of sealing ring 2 and anticorrosive effect, sealing ring 2 specifically can select rubber seal 2.The sealing ring 2 that the embodiment of the present application provides can be set to the sealing ring 2 of respective shapes according to the shape of radial direction through hole, such as, sealing ring 2 can be O RunddichtringO, square sealing ring, and the embodiment of the present application does not limit the concrete shape of sealing ring 2.
Further, be also provided with a boss in the radial direction through hole that the embodiment of the present application provides, one end of shear pin 3 and boss are sealed by sealing ring 2 and are connected.Wherein, the external diameter of one end of shear pin 3 is greater than the internal diameter of the radial direction through hole in boss, and one end of shear pin 3 can tightly be pressed on boss by the thrust that pressure cap 4 produces after screwing in radial direction through hole, strengthens the sealing between shear pin 3 and bleeder main body 1 further.
