Abstract
The utility model discloses a rapid insertion type three-way connector which comprises a three-way connector body. The three-way connector body comprises an air discharging connector. An air discharging valve is installed inside the air discharging connector. The air discharging valve comprises a valve seat fixed on the inner wall of the air discharging connector. A slope is manufactured at the inner end of the valve seat. A valve element is installed inside the valve seat. An air discharging hole is formed in the outer end of the valve element. An opening is formed in the position, located on the side wall of the valve element, of the inner end of the air discharging hole. A spring is arranged between the valve element and the air discharging connector. One end of the spring is fixed at the inner end of the valve element. The other end of the spring abuts against the inner end of the air discharging connector. A first sealing ring is arranged between the inner wall of the air discharging connector and the valve seat. A second sealing ring for sealing the slope is installed in the middle of the valve element. According to the rapid insertion type three-way connector, the air discharging valve is installed on one connector body. When the other two connector bodies are both connected to an oil way, air discharging can be carried out on the oil way through the air discharging valve, and normal work of the oil way is guaranteed.
Description
Technical field
The utility model relates to a kind of auto parts machinery, relates in particular to a kind of push-in tee union.
Background technique
It is quite general that tee union is applied in automobile (comprising oil, water and gas) pipeline connects.But, in oil circuit connects, current tee union is all to be directly installed in pipeline, easy like this making residually in oil circuit has an air, affects the normal operation of oil circuit.
The model utility content
In order to overcome defect of the prior art, the utility model provides a kind of can carry out to automobile oil-way the push-in tee union of exhaust.
The utility model solves the technological scheme that its technical problem adopts:
Push-in tee union, comprise the tee union body, it is characterized in that described tee union body comprises exhaust joint, in described exhaust joint, outlet valve is installed, described outlet valve comprises the valve seat that is fixed on the exhaust joint inwall, the inner of described valve seat is shaped with inclined-plane, in described valve seat, spool is installed, the outer end of described spool is shaped with exhaust port, the inner of described exhaust port is opened on the sidewall of described spool, between described spool and described exhaust joint, spring is arranged, one end of described spring is fixed on the inner of described spool, the other end of described spring contacts mutually with the inner of described exhaust joint, be provided with the first seal ring between described exhaust joint inwall and valve seat, the middle part of described spool is equipped with for the second seal ring with the sealing of described inclined-plane, the inner of described exhaust joint is provided with filter screen, described spring contacts mutually by described filter screen and the inner of described exhaust joint.
As the further optimization to technique scheme, described valve seat outer wall is shaped with contrary tooth, and the corresponding position of described exhaust joint inwall is shaped with the contrary teeth groove matched with described contrary toothing.
As the further optimization to technique scheme, the outer wall of described exhaust joint is shaped with outside thread.
Tee union body of the present utility model, installed outlet valve on a joint therein, when all the other two joints all are connected on oil circuit, can carry out exhaust to oil circuit by outlet valve, guaranteed the normal operation of oil circuit.
Below in conjunction with accompanying drawing, mode of execution of the present utility model is described further.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of better embodiment exhaust condition of the utility model.
Embodiment
As shown in Figure 1, a kind of push-in tee union, comprise tee union body 1, tee union body 1 comprises exhaust joint, outlet valve is installed in exhaust joint, outlet valve comprises the valve seat 2 that is fixed on the exhaust joint inwall, the inner of valve seat 2 is shaped with inclined-plane 21, spool 7 is installed in valve seat 2, the outer end of spool 7 is shaped with exhaust port 71, the inner of exhaust port 71 is opened on the sidewall of spool 7, spring 6 is arranged between spool 7 and exhaust joint, one end of spring 6 is fixed on the inner of spool 7, the other end of spring 6 contacts mutually with the inner of exhaust joint, be provided with the first seal ring 4 between exhaust joint inwall and valve seat 2, the middle part of spool 7 is equipped with for the second seal ring 8 with inclined-plane 21 sealings.
In the time of need to carrying out exhaust to pipeline, pin the outer end of spool 7 and push away inward, make with the second seal ring 8 of inclined-plane 21 sealings and leave gradually inclined-plane 21 until reach the position shown in Fig. 1, now the exhaust port 71 of spool 7 is by the space between spool 7 and exhaust joint and all the other two joint UNICOMs of tee union, smooth must be by the Bas Discharged in oil circuit.After loosing one's grip, spool 7 automatically resets under the restoring force effect of spring 6, and the second seal ring 8 contacts again with inclined-plane 21, makes exhaust joint in blocked state.
As the further optimization to technique scheme, valve seat 2 outer walls are shaped with contrary tooth 22, and the corresponding position of exhaust joint inwall is shaped with the contrary teeth groove matched with contrary tooth 22 structures.
As the further optimization to technique scheme, the inner of exhaust joint is provided with filter screen 5, and spring 6 contacts mutually by filter screen 5 and the inner of exhaust joint.
The effect of filter screen 5 is to prevent that the dirt in oil circuit from entering exhaust joint, stops up the exhaust port 71 of spool 7.
Further optimization as to technique scheme, be socketed with safety cover 3 on exhaust joint.
Further optimization as to technique scheme, be shaped with rubber tape 31 on safety cover 3, the end of rubber tape 31 is shaped with the rubber ring 33 that size matches with exhaust joint, and rubber ring 33 is enclosed within the outer wall of exhaust joint.
Further optimization as to technique scheme, be shaped with hand pulldown 33 on safety cover 3.
The effect of safety cover 3 is to prevent that extraneous dirt from entering the exhaust port 71 of spool 7.Safety cover 3 passes through rubber tape 31, rubber ring 33 is connected with exhaust joint, is to drop after preventing pulling out safety cover 3.The purpose that hand pulldown 33 is set is that to pull out safety cover 3 more laborsaving.
As the further optimization to technique scheme, the outer wall of exhaust joint is shaped with outside thread 11, and rubber ring 33 is positioned at the inboard of outside thread 11.
The effect of outside thread 11 is both to have prevented that rubber ring 33 from coming off, and the easy to exhaust joint is threaded with extraneous pipeline again.
More than describe preferred embodiment of the present utility model in detail.The ordinary skill that should be appreciated that related domain just can be made many modifications and variations according to design of the present utility model without creative work.Therefore, all technician in the art, all should fall in protection domain of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment according to design of the present utility model.
