A high-strength, earthquake-resistant valve casting

Abstract

This utility model relates to the field of valve casting technology, and in particular to a high-strength, shock-resistant valve casting. The valve casting includes a valve casting with flange 1 fixedly connected to both its left and right ends. A flange 2 is provided on one side of flange 1, and a pipe is fixedly connected to one end of flange 2. Through the cooperation of the valve casting, flange 1, flange 2, threaded rod, nut, and shock-resistant structure, the circular blocks on both sides are inserted into the grooves of flange 1 and flange 2 respectively. The threaded rod passes through the inner wall of one side of flange 1 and flange 2. Rotating the nut causes it to move on the outer wall of the threaded rod, thereby fixing flange 1 and flange 2. Flange 1 and flange 2 clamp a rubber ring. When vibration occurs, the rubber ring can buffer and absorb shock. Simultaneously, the deformation of the rubber ring compresses the spring, further buffering and absorbing shock. This facilitates shock absorption at the connection points of the valve casting, thus preventing loosening at the connection points.

Description

Technical Field

[0001] This utility model relates to the field of valve casting technology, specifically a high-strength, shock-resistant valve casting. Background Technology

[0002] Valve castings are important components for controlling the flow of media in pipelines. They are typically composed of valve bodies, valve covers, valve stems, valve discs, transmission mechanisms, and other parts.

[0003] A high-strength, earthquake-resistant valve casting (application number: 202322055976.6) is available. This design allows for adjustment via a slider, enabling protection and vibration damping for pipes of different diameters. This avoids the problems of poor versatility and inability to adjust to different pipe diameters found in existing structures, resulting in low practicality. However, the aforementioned issues persist. When using the valve casting, it needs to be connected to external pipelines. Due to the impact of water flow, vibrations are easily generated, making it difficult to perform earthquake-resistant work at the connection point. This can easily lead to loosening of the valve casting connection. Furthermore, it is inconvenient for workers to perform double-fixing work when connecting the valve casting to the pipeline, thus hindering the increase of connection strength. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of performing anti-vibration work on the connection positions of valve castings, which can easily lead to loosening of the valve casting connection positions, make it difficult for workers to perform double fixing work, and make it difficult to increase the connection fixing strength. Therefore, this invention proposes a high-strength anti-vibration valve casting.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a high-strength, earthquake-resistant valve casting, including a valve casting, with flange one fixedly connected to both the left and right ends of the valve casting, flange two provided on one side of flange one, a pipe fixedly connected to one end of flange two, threaded rods with clearance fit on one side of the inner wall of flange one and flange two, and a nut threadedly connected to one side of the outer wall of the threaded rod, and an earthquake-resistant structure provided on one side of flange one.

[0007] Preferably, the seismic-resistant structure includes circular blocks, the outer walls of the circular blocks on the left and right sides respectively having clearance fit with the outer groove of one end of flange one and the outer groove of one end of flange two, a rubber ring fixedly connected to one end of the circular block, and a spring fixedly connected to the inner wall of one side of the rubber ring.

[0008] Preferably, a crossbar is fixedly connected to the outer side of one end of the flange.

[0009] Preferably, a straight cylinder is fitted with a clearance fit on one side of the outer wall of the crossbar, and one end of the straight cylinder is fixedly connected to the outer side of one end of the flange.

[0010] Preferably, a screw is attached to one side of the crossbar via an inclined groove.

[0011] Preferably, one side of the outer wall of the screw is threaded to one side of the inner wall of the straight cylinder.

[0012] The present invention proposes a high-strength, shock-resistant valve casting with the following advantages: Through the cooperation of the valve casting, flange one, flange two, threaded rod, nut, and shock-resistant structure, the device can be used by inserting the round blocks on both sides into the grooves of flange one and flange two respectively, passing the threaded rod through the inner wall of one side of flange one and flange two, and rotating the nut to move the nut on the outer wall of the threaded rod, thereby fixing flange one and flange two. Flange one and flange two clamp the rubber ring, which can buffer and absorb vibration when vibration occurs. At the same time, the deformation of the rubber ring compresses the spring, further buffering and absorbing vibration, which facilitates the shock-resistant work of the valve casting connection position and avoids loosening of the valve casting connection position.

[0013] Through the cooperation of valve castings, threaded rods, nuts, flange one, flange two, straight cylinder, crossbar, and screw, this device can be used by inserting the crossbar into the inner wall of the straight cylinder, passing the threaded rod through flange one and flange two, and rotating the nut to move it on the outer wall of the threaded rod, thereby fixing flange one and flange two. At the same time, rotating the screw causes it to enter the inclined groove of the crossbar, and the screw and the inclined groove of the crossbar abut against each other, thereby applying an inward force to the crossbar to achieve a secondary fastening connection. This facilitates double fixing work by the operator and increases the connection strength. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings: Example 1:

[0022] See attached document Figure 1-6 In this embodiment, a high-strength earthquake-resistant valve casting includes a valve casting 1. Both ends of the valve casting 1 are fixedly connected to flange 3. Flange 4 is provided on one side of flange 3. One end of flange 4 is fixedly connected to a pipe 5. Threaded rods 6 are fitted with a clearance fit on one side of the inner wall of flange 3 and flange 4. Nuts 7 are threadedly connected to one side of the outer wall of threaded rod 6. A crossbar 10 is fixedly connected to the outer side of one end of flange 3. A slanted groove is machined on one side of the inner wall of crossbar 10.

[0023] A straight cylinder 8 is fitted with a clearance fit on one side of the outer wall of the crossbar 10. When the crossbar 10 is under force, it can move left and right on the inner wall of one end of the straight cylinder 8. One end of the straight cylinder 8 is fixedly connected to the outer side of one end of the flange 4. A screw 9 is fitted with a slanted groove on one side of the crossbar 10. One end of the screw 9 is machined into a ball head. One side of the outer wall of the screw 9 is threadedly connected to the inner wall of one side of the straight cylinder 8. An anti-vibration structure 2 is provided on one side of the flange 3. The anti-vibration structure 2 facilitates the anti-vibration work at the connection position of the valve casting 1, thereby preventing the valve casting 1 from becoming loose.

[0024] The seismic-resistant structure 2 includes a circular block 2a1. The outer walls of the circular blocks 2a1 on the left and right sides respectively fit with the outer groove of one end of flange 3 and the outer groove of one end of flange 4. The circular block 2a1 plays a positioning role for the rubber ring 2a3, and the rubber ring 2a3 plays a sealing role. One end of the circular block 2a1 is fixedly connected to the rubber ring 2a3, and one inner wall of the rubber ring 2a3 is fixedly connected to a spring 2a2, which facilitates the seismic resistance of the connection position of the valve casting 1, thereby preventing the connection position of the valve casting 1 from becoming loose.

[0025] Working principle:

[0026] When connecting valve casting 1 to pipe 5:

[0027] Insert the round blocks 2a1 on both sides into the grooves of flange 3 and flange 4 respectively. Pass the threaded rod 6 through the inner wall of one side of flange 3 and flange 4. At the same time, insert the crossbar 10 into the inner wall of the straight cylinder 8. Rotate the nut 7 so that the nut 7 moves on the outer wall of the threaded rod 6, thereby fixing flange 3 and flange 4. Flange 3 and flange 4 clamp the rubber ring 2a3. The rubber ring 2a3 plays a sealing role, thereby achieving the first connection between valve casting 1 and pipe 5. Rotate the screw 9. The screw 9 enters the inclined groove of the crossbar 10. The screw 9 abuts against the inclined groove of the crossbar 10. The screw 9 gradually moves inward, thereby giving the crossbar 10 an inward force, thereby achieving a second fastening connection, thereby achieving a double fixed connection and improving the connection strength of valve casting 1.

[0028] When vibration occurs:

[0029] When valve casting 1 is opened, water flows through pipe 5 and valve casting 1. The impact of the water flow will cause vibration. At this time, rubber ring 2a3 can buffer and dampen the vibration. At the same time, the deformation of rubber ring 2a3 compresses spring 2a2. Rubber ring 2a3 can be used as a damper to further buffer and dampen the vibration, thereby preventing the connection from becoming loose due to vibration.

[0030] Example 2:

[0031] See attached document Figure 1-6 In this embodiment, a high-strength earthquake-resistant valve casting is provided, wherein the earthquake-resistant structure 2 may further include a straight pipe 2b1, one end of which is fixedly connected to one end of flange 2 4. The outer wall of the straight pipe 2b1 is clearance-fitted with the inner wall of flange 3 and the inner wall of one end of the valve casting 1. A sealing gasket 2b3 is attached to one end of the straight pipe 2b1. The sealing gasket 2b3 is made of rubber. A circular plate 2b2 is fixedly connected to one end of the sealing gasket 2b3. An opening is machined on the inner wall of the circular plate 2b2. The outer wall of the circular plate 2b2 is fixedly connected to one side of the inner wall of the valve casting 1.

[0032] Working principle:

[0033] When connecting valve casting 1 to pipe 5, rubber ring 2a3 can provide a one-sided seal. Insert straight pipe 2b1 into the inner wall of flange 3 so that one end of straight pipe 2b1 is pressed against sealing gasket 2b3, thereby providing a second seal. This facilitates double sealing and improves the sealing effect.
