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.

As shown in fig. 1-3, the high-pressure explosion-proof valve comprises a base 1, a first connecting pipe 2 is communicated with one side of the base 1, a second connecting pipe 3 is communicated with the corresponding side of the base 1, an upper sealing barrel 4 is fixedly mounted on the top of the base 1, a fixed barrel 5 is fixedly mounted on one side of the upper sealing barrel 4, the fixed barrel 5 is far away from one end of the upper sealing barrel 4 and is provided with a rotating handle 6, a first rotating shaft 7 is fixedly connected with the center of the rotating handle 6, the first rotating shaft 7 is rotatably connected with the fixed barrel 5, the first rotating shaft 7 penetrates through the surface of the upper sealing barrel 4 and extends into the upper sealing barrel 4, a driving bevel gear 8 is fixedly connected with one end of the first rotating shaft 7, the bottom of the driving bevel gear 8 is engaged with a driven bevel gear 9, a second rotating shaft 10 is fixedly connected with the bottom of the driven bevel gear 9, a first mounting plate 11 is fixedly connected with the bottom of the second rotating shaft 10, a first mounting plate 12 is fixedly connected with the bottom of the first mounting plate 11, a flange sealing ring 16 is movably connected with a flange sealing fixing rod 16, a flange sealing ring 16 is connected with a second sealing ring 16, a flange sealing ring 16 is connected with a flange sealing ring 16, and a flange sealing ring 16 are connected with a flange sealing ring.

When the device is used, firstly, the rotating handle 6 is rotated, the rotating handle 6 drives the first rotating shaft 7 to rotate in the fixed cylinder 5, so that the first rotating shaft 7 drives the driving bevel gear 8 to rotate, then the driving bevel gear 8 drives the driven bevel gear 9 to rotate, the driven bevel gear 9 drives the second rotating shaft 10 to rotate, then the second rotating shaft 10 drives the first mounting plate 11 to drive the ball valve 12 to rotate, the through hole of the ball valve 12 is aligned with the opening of the second connecting pipe 3, so that the first connecting pipe 2 is communicated with the second connecting pipe 3 through the base 1, when liquid passing through the base 1 between the first connecting pipe 2 and the second connecting pipe 3, the liquid flowing in the ball valve 12 is not easy to flow out due to the fact that the first connecting pipe 2 and the second connecting pipe 3 are tightly attached to the ball valve 12, when the pressure is too large, and part of the liquid flows out from the communication part of the first connecting pipe 2 or the second connecting pipe 3 and the ball valve 12, this part of liquid can first sealed flange 14 intercept at first, because first sealed flange 14 cooperates 16 pressurization sealing washer 15 of second sealed flange, thereby sealing washer 15 carries out radial seal to second pivot 10, play the effect of secondary seal, thereby liquid is difficult for flowing out from the junction of second pivot 10 and sealing washer 15, when pressure breaching the joint strength between sealing washer 15 and the second pivot 10, water pressure promotes first sealed flange 14 and drives sealing washer 15 and drive second sealed flange 16 and promote spring 18, thereby second sealed flange 16 promotes dead lever 19 and passes limiting plate 20, prevent that the too big explosion of pressure from opening in base 1, utilize the inner space of first connecting pipe 2 to cushion, realize anti high pressure explosion-proof effect.

Specifically, first connecting pipe 2 is the same with 3 diameters of second connecting pipe, just with ball valve 12 sliding connection between first connecting pipe 2 and the second connecting pipe 3, the equal fixed mounting in 1 inner wall both sides of base has second mounting panel 13, second mounting panel 13 and ball valve 12 one side sliding connection. In practice, the ball valve 12 blocks the first connecting pipe 2 and the second connecting pipe 3, the opening of the ball valve 12 is aligned to the first connecting pipe 2 and the second connecting pipe 3 after rotation, the first connecting pipe 2 and the second connecting pipe 3 can also be communicated, when the two non-opening walls of the ball valve 12 rotate to the second mounting plate 13, the second mounting plate 13 can support the two sides of the ball valve 12, and the ball valve 12 is more stably mounted.

The first sealing flange 14 and the second sealing flange 16 are connected by fastening bolts 17, and in practice, the first sealing flange 14 and the second sealing flange 16 provide an axial seal for the second rotating shaft 10. In the present embodiment, the first sealing flange 14 and the second sealing flange 16 clamp the sealing ring 15, so that the sealing ring 15 clamps the side surface of the second rotating shaft 10, and the sealing ring 15 performs radial sealing on the second rotating shaft 10.

In reality, go up 4 inner walls of a section of thick bamboo and limiting plate 20 outside fixed connection, just limiting plate 20 top and second pivot 10 top through connection utilize spring 18 to promote second sealing flange 16, treat that water pressure too big dashes when second sealing flange 16 removes, second sealing flange 16 promotes spring 18 and promotes dead lever 19 and passes limiting plate 20, and in fig. 2, left dead lever 19 is staggered with first pivot 7, collides with first pivot 7 when preventing dead lever 19 from moving up, utilizes the inner space of an upper seal section of thick bamboo 4 as partial buffering, prevents that base 1 from bursting open.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. 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.
