Abstract

The utility model discloses a plug device of a water inlet pipe and a water outlet pipe of an automobile radiator. The plug device comprises a valve body, a valve core and an air inlet joint, wherein a seal ring A and a seal ring B are arranged between the valve body and the valve core. The large end of the valve core is installed with the air inlet joint, and the small end of the valve core is fixedly provided with a check ring through a screw. A seal rubber is arranged between the check ring and the valve body. According to the plug device, the seal rubber can be subjected to compressive deformation through the inflow of compressed air which is served as a power mechanism, so that the effect of sealing the water inlet pipe and the water outlet pipe is achieved. The plug device has the advantages of being simple in structure, convenient to operate, safe and reliable and capable of being widely applied in the technical field of leakage detection of radiators.

Description

A kind of automobile radiators turnover water pipe end cap

Technical field

The utility model belongs to radiator leak hunting technology field, relates to a kind of automobile radiators turnover water pipe end cap.

Background technique

Along with current automotive industry develops rapidly, supporting automobile radiators also obtains the development of advancing by leaps and bounds with it, and along with the continuous increase of radiator output, corresponding technology also is used widely, simultaneously the quality requirement of radiator also improved constantly, particularly to the requirement of radiator seepy question.Present pipe stopper mostly adopts rubber stopper directly to fill in the water pipe and installs and fixes, plug is connected on the mouth of pipe of pipeline, if this obstruction mode is when the pipe end blocking binding is not tight, come off from the mouth of pipe easily, even pipe end blocking is fixing very firm, be subjected in the situation of larger pressure, there is potential safety hazard in the rubber stopper pipeline opening that flies out that also can expand.

The model utility content

For addressing the above problem, the utility model provides a kind of automobile radiators turnover water pipe end cap, and this device can fast and effeciently seal water pipe, and in use Security is good, simple, convenient.

The utility model is achieved by following technical solution.

A kind of automobile radiators turnover water pipe end cap, comprise valve body, spool and air input joint, be provided with seal ring A and seal ring B between described valve body and the spool, the end that spool is large is installed air input joint, a little end is fixed with back-up ring by screw, is provided with sealed rubber between back-up ring and valve body.

Described back-up ring and sealed rubber external diameter are than the little 1.5～2mm of turnover water pipe internal diameter that is complementary with it.

Described sealed rubber is tightly placed on the spool, and spool outer wall and valve interior wall radially are being provided with the gap.

Compared with prior art, the utility model is to the good sealing effect of intake pipe, and the effect of Effective Raise radiator aspect leak detection improves speed of production, and be simple in structure, easy to operate, safe and reliable.

Fig. 1 is the utility model structural representation;

Fig. 2 is that the C of Fig. 1 is to view.

Among the figure: 1-valve body, 2-spool, 3-air input joint, 4-sealed rubber, 5-back-up ring, 6-screw.

Embodiment

Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.

As shown in Figure 1 and Figure 2, a kind of automobile radiators turnover water pipe end cap, comprise valve body 1, spool 2 and air input joint 3, be provided with seal ring A and seal ring B between described valve body 1 and the spool 2, spool 2 large ends are installed air input joint 3, a little end is fixed with back-up ring 5 by screw 6, is provided with sealed rubber 4 between back-up ring 5 and valve body 2.

Described back-up ring 5 and sealed rubber 4 external diameters are than the little 1.5～2mm of turnover water pipe internal diameter that is complementary with it.

Described sealed rubber 4 is tightly placed on the spool 2, and spool 2 outer walls and valve body 1 inwall radially are being provided with the gap.

Working principle of the present utility model is as follows:

As shown in Figure 1, compressed air hose is connected with air input joint 3, guarantees sealing; Then this device is put into turnover water pipe, make valve body 1 small end cylndrical surface put in the caliber fully; Open pressurized air, this moment is under compressed-air actuated drive, spool 2 can move upward, valve body 1 keeps motionless, spool 2 drives back-up ring 5 and moves upward, and this moment, back-up ring 5 and valve body 1 will be squeezed in sealed rubber 4 between the two, makes sealed rubber 4 produce distortion, cause the radial dimension of sealed rubber 4 to expand change greatly, thereby reach sealing orifice; After having detected radiator, the closes compression air, spool 2 is return under the active force of sealed rubber 4, just very easily this device is taken out from the radiator mouth of pipe, and is easy to operate and effect is fine, can extensively promote the use of in radiator leak hunting technology field.
