Description

Non-return device for high-pressure-resistant driving valve

Technical Field

The utility model relates to the technical field of valves, specifically be a high pressure resistant drives check device for valve.

Background

Valves used in fluid control systems range in variety and size from the simplest shut-off valves to the variety of valves used in extremely complex autonomous systems. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like.

A check plate is arranged in an existing driving valve and used for preventing fluid in the valve from flowing reversely, but the check plate is in a free state, and when pressure is not available, the check effect is poor, and therefore a check device for the high-pressure-resistant driving valve is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high pressure resistant drive valve is backstop for door to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high pressure resistant drive valve is check device for door, includes the valve body, the left end fixed mounting of valve body violently manages, the inside wall fixed mounting who violently manages has solid fixed ring, gu fixed ring's right flank top fixed mounting has the L shaped plate, the bottom of L shaped plate articulates there is the check plate, the right flank fixed mounting of check plate has first fixed block, the right-hand member of first fixed block articulates there is the one end of spring and telescopic link, the other end of spring and telescopic link articulates there is the second fixed block, the top fixed mounting of second fixed block is on the inside wall top of violently managing.

Preferably, a rubber layer is fixedly mounted on the left side surface of the non-return plate.

Preferably, the left end of the transverse pipe is welded with a connecting flange.

Preferably, the telescopic rod comprises a cross column, one end of the cross column is provided with a cylindrical groove, and a cross rod is slidably mounted in the cylindrical groove.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses an install at the left end of valve body and violently manage, violently be equipped with solid fixed ring and backstop board in the pipe, be connected with spring and telescopic link through first fixed block on the backstop board, the other end of spring and telescopic link passes through the second fixed block and connects on violently managing the inner wall, through the elasticity of spring, can make backstop board in close contact with on solid fixed ring, and then increase the pressure effect of backstop board, avoid having the fluid to increase the contact effect of backstop board and solid fixed ring when the process, avoid the fluid to flow back, increase the backstop effect.

Drawings

Fig. 1 is an overall schematic view of the present invention.

Fig. 2 is a schematic view of the horizontal tube of the present invention.

In the figure: 1. the valve comprises a valve body, a transverse pipe 2, a transverse pipe 3, a fixing ring 4, an L-shaped plate 5, a check plate 6, a first fixing block 7, a spring 8, a second fixing block 9, a telescopic rod 10, a rubber layer 11 and a flange plate.

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 and fig. 2, the present invention provides a technical solution: the utility model provides a high pressure resistant drives check device for valve, including valve body 1, valve body 1's left end fixed mounting violently manages 2, violently manage 2 for with valve body 1's integrated into one piece structure, violently manage 2 inside wall fixed mounting have solid fixed ring 3, gu fixed ring 3's right flank top fixed mounting has L shaped plate 4, L shaped plate 4's bottom articulates there is check plate 5, check plate 5's right flank fixed mounting has first fixed block 6, the right-hand member of first fixed block 6 articulates there is the one end of spring 7 and telescopic link 9, fig. 1, 2 shown spring 7 is in the compression state, the other end of spring 7 and telescopic link 9 articulates there is second fixed block 8, the top fixed mounting of second fixed block 8 is on violently managing 2's inside wall top, first fixed block 6 and second fixed block 8 are the inside integrated into one piece structure of violently managing 2.

Specifically, a rubber layer 10 is fixedly mounted on the left side surface of the non-return plate 5, and the rubber layer 10 is arranged to increase the contact sealing effect of the non-return plate 5 and the fixing ring 3.

Specifically, the left end welding of violently pipe 2 has connection flange 11, the setting of connection flange 11 for conveniently replace the left end and the pipeline of valve body 1 and be connected.

Particularly, telescopic link 9 includes the spreader, and the one end of spreader is equipped with the cylinder groove, and slidable mounting has the horizontal pole in the cylinder groove, and spreader and horizontal pole are the different cylinder body of rod of diameter.

The working principle is as follows: when the left end of the horizontal pipe 2 flows into the water flow, the water pressure contacts the check plate 5, so that the bottom end of the check plate 5 is turned upwards to the right, the fixing ring 3 is opened, the water flow flows into the valve body 1, and if the water flow flows leftwards from the valve body 1, the spring 7 can be used for compressing the elasticity to enable the check plate 5 to be in close contact with the fixing ring 3, and the water flow backflow is avoided.

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.
