Abstract
The utility model provides a tee bend air bleeding valve assembly, includes that the tee bend air bleeding valve connects and the gassing bolt, the I concave circular conical surface that is tightly linking the valve opening mouth at the sealed end that the tee bend air bleeding valve connects, the sealed end II of gassing bolt is the dome conical surface of its lower extreme, the circular cone angle of the concave circular conical surface is 120, the circular cone angle of the dome conical surface is 123 -125, the sealed end II of gassing bolt, sealed end that to be the dome conical surface connect with the tee bend air bleeding valve I, the sealing line who forms when being concave circular conical contact drop on in the concave circular conical surface. The processing of this tee bend air bleeding valve assembly's gassing bolt is convenient, and requires not highly to the axiality of the processing of tee bend air bleeding valve joint sealing terminal surface, has improved the uniformity of product, under the prerequisite of the gassing function of guaranteeing tee bend air bleeding valve assembly and oil pressure leakproofness, has improved the qualification rate of product to reduce cost.
Description
Technical field
The utility model relates to a kind of vehicle component, particularly a kind of three-way exhaust valve assembly.
Background technique
Three-way exhaust valve assembly is connected between clutch main cylinder assembly and clutch by oil pipe, and its Main Function has:
1. connect the oil pipe between clutch main cylinder assembly and clutch;
2. play degassing when filling clutch fluid;
3. after filling clutch fluid, play the effect of sealing and transmission oil pressure.
The sealing of three-way exhaust valve assembly, mainly makes the sealed end generation extrusion-deformation of itself and three-way exhaust valve joint by the bleeder screw tightened in three-way exhaust valve assembly thus forms linear sealing to realize.
The sealed end of the bleeder screw of existing three-way exhaust valve assembly is 90 ° of dome conical surfaces, the sealed end of the three-way exhaust valve joint coordinated with it is 120 ° of concave cone faces, when bleeder screw and three-way exhaust valve joint close contact, the potted line that the dome conical surface of bleeder screw and three-way exhaust valve joint are formed is just in time the recessed conical surface of three-way exhaust valve joint and the aperture circumference of the handing-over line of valve opening, i.e. valve opening, as shown in Figure 5.
The deficiency of the three-way exhaust valve assembly existence of this kind of structure: require higher to the quality of three-way exhaust valve joint sealing end processing and coaxality in production, quality of product not easily ensures, increases difficulty and the cost of production of processing.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of three-way exhaust valve assembly that can improve again production up-to-standard rate meeting product venting function and oil pressure sealing requirements while, to overcome the deficiencies in the prior art.
The technological scheme that the utility model is taked is: a kind of three-way exhaust valve assembly, comprise three-way exhaust valve joint and bleeder screw, the sealed end I of described three-way exhaust valve joint is for being close to the recessed conical surface of valve orifice, the sealed end II of described bleeder screw is the dome conical surface of its lower end, the cone angle of described recessed conical surface is 120 °, the cone angle of the described dome conical surface is 123-125 °, and the potted line formed when the sealed end I of the sealed end II of described bleeder screw, i.e. the dome conical surface and three-way exhaust valve joint, i.e. recessed conical surface contact drops in recessed conical surface.
Owing to taking technique scheme, a kind of three-way exhaust valve assembly of the utility model has following beneficial effect:
1. a kind of three-way exhaust valve assembly of the utility model is owing to improving the convex frustoconical bevel angle of bleeder screw, when the convex cone face of bleeder screw contacts with the sealed end of three-way exhaust valve joint, its potted line formed is not in valve orifice, but move in the recessed conical surface of three-way exhaust valve joint outward, therefore airtight quality easily ensures, less demanding to the coaxality of the processing of three-way exhaust valve joint sealing end face, the up-to-standard rate of product is high, reduces costs;
2. the utility model a kind of three-way exhaust valve assembly bleeder screw just change convex frustoconical bevel angle, do not increase difficulty of processing, structure is simple, easy realization, processing high conformity, sealing is more reliable, can better meet venting function and the favourable production of oil pressure sealing requirements of three-way exhaust valve assembly.
Be further described below in conjunction with the technical characteristics of drawings and Examples to a kind of three-way exhaust valve assembly of the utility model.

Embodiment
Embodiment one
As shown in Figure 1 to Figure 3, a kind of three-way exhaust valve assembly, comprise three-way exhaust valve joint 1 and bleeder screw 2, the sealed end I 11 of described three-way exhaust valve joint 1 is for being close to the recessed conical surface of valve orifice, the sealed end II 21 of described bleeder screw 2 is the dome conical surface of its lower end, the cone angle of described recessed conical surface is 120 °, the cone angle of the described dome conical surface is 123-125 °, and the potted line 5 formed when the sealed end I of the sealed end II of described bleeder screw 2, i.e. the dome conical surface and three-way exhaust valve joint 1, i.e. recessed conical surface contact drops in recessed conical surface.
During use, after dust-proof cover 3 is passed screw thread from the sealed end II 21 of bleeder screw 2, bleeder screw 2 is screwed into three-way exhaust valve joint 1, then the moment of 10Nm ~ 12Nm is tightened, finally in three-way exhaust valve assembly, set up 0.45MPa air pressure by gas inspection method and put into water and detect sealing, if bubble-free is emerged from the vent hole 4 of bleeder screw 2, product is qualified, otherwise defective.Detect qualified after three-way exhaust valve assembly is connected between clutch main cylinder assembly and clutch by oil pipe, manually the bleeder screw 2 being in sealing tight condition is unscrewed, open the dust-proof cover 3 on bleeder screw 2, pipe-line system is connected with the external world, gas in clutch system is treated to drain, namely time from vent hole 4 trickle of bleeder screw 2, then bleeder screw 2 is tightened sealing, reach the effect of oiling of carrying out exitting to clutch system.
