Description

Technical Field

[0001] The utility model relates to the technical field of leakage-proof low-loss dual-control ball valves, in particular to a leakage-proof low-loss dual-control ball valve. Background Art

[0002] The fluid channel design of the double control ball valve is reasonable, and the resistance generated when the fluid passes through the valve is small, thereby reducing energy consumption.

[0003] For example, a double-control ball valve with the authorization announcement number "CN210770360U" adopts a double-sealed structural design. The sealing of the device is achieved by the cooperation of the sealing pair with the valve plate and the valve seat with the valve ball, which avoids oil leakage and improves the sealing effect of the device. Through the combination of the ball valve and the gate valve, the flow rate can be adjusted while the pipeline is quickly opened and closed, thereby improving the control accuracy of the flow rate. However, when the double-control ball valve is used, its own weight is relatively large. When the double-control ball valve is opened, the instantaneous pressure is very large, which will cause the double-control ball valve to shake. The heavy weight of the double-control ball valve will increase its own shaking, increasing the load-bearing load at the connection between the double-control ball valve and the pipeline, making it prone to breakage and damage, resulting in insufficient connection stability of the double-control ball valve, affecting the normal use of the double-control ball valve. Summary of the Invention

[0004] The utility model aims to solve the problem that the connection stability of a double control ball valve is insufficient and affects the normal use of the double control ball valve, and proposes a leakage-proof and low-loss double control ball valve.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

The outer wall end of the straight pipe is fixedly connected to the inner wall of the flange, the inner side of the straight pipe is fixedly connected to the ball valve, the outer wall of the straight pipe is connected to a supporting structure, the inner wall of the straight pipe is connected to a sealing structure, and the top valve stem of the ball valve is fixedly connected to a handle.

[0007] Preferably, the supporting structure includes an arc plate and a straight plate, the inner wall of the arc plate fits with the outer wall of the straight tube, the left and right sides of the arc plate are respectively fixed to the inner side of the straight plate, the inner wall of the straight plate is threadedly connected with a bolt, the bottom of the arc plate located below is fixed with a screw, the outer wall of the screw is threadedly connected with a vertical cylinder, and the bottom of the vertical cylinder is fixed with a bottom plate.

[0008] Preferably, the outer wall of the bottom plate is processed with multiple threaded openings.

[0009] Preferably, the inner side of the outer wall of the arc plate fits with the outer wall of the ball valve.

[0010] Preferably, the sealing structure includes a first circular tube and a protective pad, the outer wall of the first circular tube is plugged into the inner wall of the straight tube, the outer side of the first circular tube is fixedly connected to the inner side of the protective pad, and the outer side of the protective pad is fixedly connected to the second circular tube.

[0011] Preferably, the threaded opening on the outer wall of the protective gasket has the same inner diameter as the threaded opening on the outer wall of the flange.

[0012] The utility model proposes a leakage-proof and low-loss double-control ball valve, which has the following beneficial effects: the inner wall of the arc plate is fitted with the outer wall of the straight pipe through the supporting structure, and the outer walls of the upper and lower straight plates are then fitted, and then the bolts are threaded from top to bottom through the fitted straight plates to complete the fixation of the arc plate and the straight pipe, and then the vertical cylinder is rotated downward by the screw, so that the vertical cylinder moves downward with the bottom plate, so that the bottom of the bottom plate is pressed against the ground, thereby achieving support for the straight pipe and the ball valve, ensuring the connection stability of the double-control ball valve, and ensuring the normal use of the double-control ball valve.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings: Example

[0019] See also Figures 1-4: In this embodiment, a leakage-proof and low-loss double-control ball valve includes a straight pipe 1 and a flange 4. The outer wall end of the straight pipe 1 is fixedly connected to the inner wall of the flange 4, and a ball valve 5 is fixedly connected to the inner side of the straight pipe 1. How to operate and use the ball valve 5 is already existing technology. The model is selected according to usage requirements and will not be elaborated on. The outer wall of the straight pipe 1 is connected to the supporting structure 2, and the inner wall of the straight pipe 1 is connected to the sealing structure 3. The top valve stem of the ball valve 5 is fixedly connected to a handle 6, which facilitates the rotation of the valve stem of the ball valve 5.

[0020] The supporting structure 2 includes an arc plate 201 and a straight plate 202. The inner wall of the arc plate 201 fits the outer wall of the straight tube 1. The left and right sides of the arc plate 201 are respectively fixed to the inner side of the straight plate 202. The inner wall of the straight plate 202 is threadedly connected with a bolt 203. The bolt 203 fixes the two straight plates 202 that fit together. The bottom of the lower arc plate 201 is fixed with a screw 204. The outer wall of the screw 204 is threadedly connected with a vertical cylinder 205. The vertical cylinder 205 is rotated up and down by the outer wall of the screw 204 under force. The bottom of the vertical cylinder 205 is fixed with a bottom plate 206. The outer wall of the bottom plate 206 is processed with multiple threaded openings. The inner side of the outer wall of the arc plate 201 fits the outer wall of the ball valve 5.

[0021] The inner wall of the arc plate 201 is fitted with the outer wall of the straight pipe 1 through the support structure 2. At this time, the outer walls of the upper and lower straight plates 202 are fitted. Then the bolts 203 are threaded from top to bottom through the fitted straight plates 202 to complete the fixation of the arc plate 201 and the straight pipe 1. Then the vertical cylinder 205 is rotated downward by the screw 204, so that the vertical cylinder 205 moves downward with the bottom plate 206, so that the bottom of the bottom plate 206 is pressed against the ground, thereby achieving support for the straight pipe 1 and the ball valve 5, ensuring the connection stability of the dual-control ball valve, and ensuring the normal use of the dual-control ball valve.

[0022] The sealing structure 3 includes a first circular tube 301 and a gasket 302. The outer wall of the first circular tube 301 is plugged into the inner wall of the straight tube 1. The outer side of the first circular tube 301 is fixedly connected to the inner side of the gasket 302. The gasket 302 is made of rubber and plays a role in connection and sealing. The outer side of the gasket 302 is fixedly connected to the second circular tube 303. The outer wall threaded opening of the gasket 302 is consistent with the inner diameter of the outer wall threaded opening of the flange 4.

[0023] Working principle:

[0024] Installation of anti-leakage low-loss double control ball valve:

[0025] The inner walls of the two straight pipes 1 are respectively inserted into the outer wall of the first circular pipe 301 until the outer wall of the gasket 302 fits with the outer wall of the flange 4. Then the inner wall of the external pipe is inserted into the second circular pipe 303 and fits with the other side of the gasket 302. Then the screws are passed through the external pipe connection, the gasket 302 and the flange 4 to fix them. The gasket 302 can prevent leakage after the ball valve 5 is connected.

[0026] Leak-proof and low-loss dual control ball valve support:

[0027] The inner wall of the arc plate 201 is made to fit with the outer wall of the straight pipe 1. At this time, the outer walls of the upper and lower straight plates 202 are fit. Then the bolts 203 are threaded from top to bottom through the fitted straight plates 202 to complete the fixation of the arc plate 201 and the straight pipe 1. Then the vertical cylinder 205 is rotated downward by the screw 204, so that the vertical cylinder 205 moves downward with the bottom plate 206, so that the bottom of the bottom plate 206 is pressed against the ground, thereby supporting the straight pipe 1 and the ball valve 5, avoiding damage to the connection of the ball valve 5, and reducing loss. When the bottom plate 206 is far from the ground, the fixed position of the arc plate 201 is changed so that the bottom plate 206 faces the wall, and then the bottom plate 206 is fit with the wall. Then the screws are passed through the bottom plate 206 and fixed to the wall. By turning the handle 6, the valve stem of the ball valve 5 is rotated and the internal valve ball is rotated to realize the opening and closing of the ball valve 5. Example

[0028] See also Figures 1-4 : In this embodiment, a leakage-proof and low-loss dual-control ball valve also includes a round block 7, the bottom of which is fixedly connected to the top valve stem of the ball valve 5.

[0029] Working principle:

[0030] Insert the rod corresponding to the notch on the top of the round block 7, and rotate the round block 7 by the rotation of the rod. The rotating round block 7 rotates the valve stem on the top of the ball valve 5, and cooperates with the control of the handle 6 to achieve dual control.
