Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1 to 3, the present invention provides a technical solution: oil tank valve test joint sealing mechanism, including sealing mechanism 4 and oil tank valve 11, a side surface of oil tank valve 11 is equipped with the air outlet nozzle 12 of integral type, sealing mechanism 4 includes air inlet 41, piston 42, sealing washer 43 and seal structure, piston 42 and sealing washer 43 all set up the inside at sealing mechanism 4, and sealing washer 43 sets up the tip at piston 42, air inlet 41 is seted up in one side of sealing mechanism 4, the jack corresponding with air outlet nozzle 12 has been seted up to sealing mechanism 4's the opposite side surface, can improve oil tank valve 11's test stability and leakproofness.

In this embodiment, preferably, the sealing structure includes a plurality of O-rings 44, the O-rings 44 are disposed between the piston 42 and the inner wall of the sealing mechanism 4, a plurality of annular grooves corresponding to the O-rings 44 are formed on the surface of the piston 42, the O-rings 44 are disposed in the annular grooves, and the outer edges of the O-rings 44 are tightly attached to the inner wall of the sealing mechanism 4, so that the sealing effect can be achieved when the piston 42 moves, and the stability of the sealing mechanism 4 is further improved.

In this embodiment, it is preferable that the air inlet 41 is communicated with the inner side of the sealing mechanism 4 for connecting an external air inlet device to push the piston 42, and the end of the air outlet nozzle 12 is inserted into the inner side of the sealing ring 43 through the insertion hole.

The utility model discloses a theory of operation and use flow: this sealing mechanism 4 is when using, the direction of oil tank valve 11 product toward sealing mechanism 4 under external accredited testing organization's effect removes, cause the inside that air outlet nozzle 12 inserted sealing mechanism 4 through the jack, cause the tip of air outlet nozzle 12 to be wrapped by sealing mechanism 4's sealing washer 43 simultaneously, thereupon air inlet 41 admits air the back and promotes piston 42 compression sealing washer 43, make sealing washer 43 hug closely air outlet nozzle 12 and realize sealedly, thereby stability when improving the product test, and when air inlet 41 switches into not admitting air, sealing washer 43 can open automatically, air outlet nozzle 12 can freely withdraw from, accomplish the test of oil tank valve 11.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
