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.

Referring to fig. 1 to 4, a reusable pop-off valve includes a central body 1, a connector 2 connected to an outer side of the central body 1, and the outer side of the intermediate body 1, which is positioned at one side of the joint 2, is provided with a C-shaped snap spring 4, the inside of the joint 2 is provided with a framework oil seal 3, the inside of the intermediate body 1 is provided with a sealing ring 5, a sealing seat 6 is arranged inside the intermediate body 1 and positioned outside the sealing ring 5, a first sealing ring 7 is arranged inside the intermediate body 1 and positioned outside the sealing seat 6, a clamp spring 8 is arranged on one side of the sealing seat 6 in the middle body 1, a valve seat 9 is connected with the inside of the sealing seat 6 in the middle body 1, and the outer side of the valve seat 9 is provided with a second sealing ring 10, the inner part of the valve seat 9 is provided with a spring 11, and one side of the spring 11 is connected with a valve core 12, and a connecting block 14 is arranged inside the valve core 12.

Please refer to fig. 1 and fig. 2, the inside of the joint 2 is connected to the intermediate body 1 by a framework oil seal 3, and the joint 2 is connected to the intermediate body 1 by a C-type snap spring 4, so that the joint 2 can be rotatably connected to the outside of the intermediate body 1, and the joint 2 is not easily separated from the outside of the intermediate body 1.

Please refer to fig. 1, a sinking groove is formed on one side of the sealing seat 6, and the sealing seat 6 is connected to the intermediate body 1 by the snap spring 8, so that the sealing seat 6 is more stable in the intermediate body 1, and the liquid is not easy to seep out from the outer side of the sealing seat 6.

Please refer to fig. 1, one side of the valve seat 9 is located between the inner side of the sealing seat 6 and the outer side of the sealing ring 5, and a clamping groove clamped with the clamp spring 8 is arranged on the outer side of the valve seat 9, so that when the valve seat 9 is clamped inside the intermediate body 1, oil inside the valve seat 9 is not easy to leak out, and the sealing performance of the valve body is enhanced.

Please refer to fig. 3 and 4, a limiting seat 13 is disposed on one side of the valve core 12, and the valve core 12 is connected to the spring 11 by the limiting seat 13, so that the spring 11 is not easily separated from the top end of the valve core 12, and the probability of valve damage is reduced.

Referring to fig. 4, the number of the connecting blocks 14 is four, the four connecting blocks 14 are equidistantly distributed inside the valve core 12, the valve core 12 can be pressed against the sealing ring 5 by the four connecting blocks 14, and therefore, the liquid can flow in between the four connecting blocks 14.

The working principle is as follows: when the anti-explosion valve is used, the valve seat 9 is required to be in butt joint with an oil supply pipe of an oiling machine, the joint 2 is required to be in butt joint with an oiling joint, the anti-explosion valve is installed, as the valve core 12 of the anti-explosion valve is in a normally open state under the action of the sealing ring 5, oil in the oil pipe can flow into the middle body 1 through the four groups of connecting blocks 14 in the valve core 12 and flow into the oiling joint through the middle body 1, when the oiling joint applies large tensile force, the axial force borne by the anti-explosion valve exceeds the maximum pressure borne by the design, the snap spring 8 in the anti-explosion valve is extruded by the valve seat 9, after the snap spring 8 is expanded, the valve seat 9 is separated from the middle body 1, at the moment, the four groups of connecting blocks 14 in the valve core 12 do not prop against the sealing ring 5, at the moment, the valve core 12 is rapidly closed, make the inside oil of disk seat 9 blocked at the inside of disk seat 9 by valve core 12 is sealed, the midbody 1 that will break away from this moment is gone into the outside of disk seat 9 once more, make the one end of disk seat 9 stretch into between 5 outsides of sealing ring and the 6 inboards of seal receptacle, make jump ring 8 block into the outside draw-in groove of disk seat 9 once more, make the abruption valve accomplish the butt joint once more, when refuel the interface and exert pulling force to the abruption valve and make joint 2 produce deformation, through taking off C type jump ring 4, make the joint 2 that damages can break away from the outside of midbody 1, use new joint 2 to cup joint the outside at midbody 1 this moment, and block C type jump ring 4 into the outside of midbody 1 once more.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
