Description

Technical Field

[0001] This utility model belongs to the technical field of high-temperature bellows valves, specifically relating to a high-temperature bellows valve. Background Technology

[0002] A high-temperature bellows valve is a valve specifically designed for high-temperature environments. It mainly consists of a valve body, valve cover, valve disc, valve stem, bellows sealing assembly, handwheel, and other components. The bellows, as the key sealing element, achieves the valve's sealing function through its elastic deformation. The valve disc moves up and down along the valve seat centerline to open and close the flow. Generally, when operating in high-temperature environments, high-temperature bellows valves may experience vibration and noise due to temperature changes and media pressure fluctuations, which can affect the valve's stability and service life to some extent.

[0003] Existing high-temperature bellows valves generally operate in high-temperature environments. Due to temperature changes and medium pressure fluctuations, they may generate vibrations and noises, which may affect the stability and service life of the valves to some extent. Therefore, vibration damping mechanisms are needed to absorb valve vibrations, reduce the impact of vibrations on the valves and pipelines, and thus maintain the overall stability of operation. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature bellows valve for existing devices, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-temperature bellows valve, including a valve body, with shock-absorbing components movably connected to both sides of the outer wall of the valve body. The shock-absorbing components include a mounting frame, with limit screws provided on the outer wall of the mounting frame, a shock-absorbing spring provided on one side of the outer wall of the mounting frame, a damper provided on one side of the outer wall of the mounting frame, a mounting bracket provided on the outer wall of the shock-absorbing spring, a screw provided on the outer wall of the mounting bracket, a nut provided on the outer wall of the screw, an installation groove provided on the outer wall of the mounting bracket, and slots provided at equal intervals on the outer wall of the installation groove.

[0006] To better solve the above-mentioned technical problems, this utility model provides a further technical solution: the outer wall of the mounting frame is threadedly connected to the limiting screws, the limiting screws are evenly distributed on the outer wall of the mounting frame, the limiting screws are threadedly connected to the valve body, and the mounting frame and the valve body form a detachable structure through the limiting screws. Through the cooperation between the mounting frame and the limiting screws, it is convenient to install and disassemble the mounting frame during use, thereby facilitating the replacement and maintenance of the mounting frame and improving the overall ease of use.

[0007] To better solve the above-mentioned technical problems, this utility model provides a further technical solution: one side of the outer wall of the mounting frame is connected to one side of the outer wall of the shock-absorbing spring, and the other side of the outer wall of the shock-absorbing spring is connected to one side of the outer wall of the mounting bracket. The shock-absorbing springs are evenly distributed on one side of the outer wall of the mounting frame. The interior of the shock-absorbing spring is movably connected to the outer wall of the damper. One end of the outer wall of the damper is connected to one side of the outer wall of the mounting frame, and the other end of the outer wall of the damper is connected to one side of the outer wall of the mounting bracket. Through the cooperation between the shock-absorbing spring, the damper, and the mounting bracket, a certain degree of buffering is easily improved during use, thereby absorbing the vibration of the valve body, reducing the impact of vibration on the valve body and pipeline, and thus maintaining the overall stability of use.

[0008] To better solve the above-mentioned technical problems, this utility model provides a further technical solution: the outer wall of the mounting bracket is threadedly connected to the outer wall of the screw, the screws are evenly distributed on the outer wall of the mounting bracket, and the screws and nuts are threadedly connected. Through the cooperation between the screws and nuts, the mounting bracket can be easily installed and disassembled during use, thereby improving the convenience of installation.

[0009] To better solve the above-mentioned technical problems, this utility model provides a further technical solution: the inner wall of the mounting frame is connected with a rubber ring, and the rubber ring and the mounting frame form an integrated structure. Under the action of the rubber ring, it is easy to improve the tightness of the connection between the mounting frame and the valve body.

[0010] To better solve the above-mentioned technical problems, this utility model provides a further technical solution: a locking block is engaged inside the slot, and an installation ring is connected to one end of the outer wall of the locking block. The installation ring is movably connected to the installation slot, and a sealing ring is connected to one side of the outer wall of the installation ring. Through the cooperation between the locking block, the installation ring, and the sealing ring, the sealing ring can be easily installed and disassembled during use, thereby facilitating the replacement and cleaning of the sealing ring. Under the action of the sealing ring, the tightness of the connection between the mounting bracket and the pipeline is improved.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] By incorporating a damping component and a rubber ring, the mounting frame is movably connected to the outer wall of the valve body during use. The rubber ring enhances the tightness of the connection between the mounting frame and the valve body. The limit screw is threaded into the valve body, thus fixing the mounting frame in place. The limit screw facilitates the installation and removal of the mounting frame, making it easy to replace and maintain. The valve body is connected to the pipeline, and the screw is threaded into the pipeline connector. The nut is then threaded into the outer wall of the screw to lock it in place, thus installing the valve body to the pipeline. During operation, vibrations caused by temperature changes and medium pressure fluctuations compress the damping spring. The spring absorbs the pressure through its extension and rebound, improving buffering capacity and preventing vibration and noise from affecting the stability and accuracy of the valve body. Simultaneously, the damper prevents the damping spring from continuously swaying, thereby improving overall stability during use.

[0013] By incorporating a slot, mounting ring, locking block, and sealing ring, the locking block engages with the slot during use, thereby driving the mounting ring and sealing ring to install. This improves the tightness of the connection between the mounting bracket and the pipeline, preventing liquid or gas leakage. The locking block also facilitates the installation and removal of the sealing ring, making it easy to replace and clean, thus enhancing overall safety. Attached Figure Description

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-3 A high-temperature bellows valve includes a valve body 1. Both sides of the outer wall of the valve body 1 are movably connected to a shock-absorbing component 2. The shock-absorbing component 2 includes a mounting frame 201. The outer wall of the mounting frame 201 is provided with a limit screw 202. A shock-absorbing spring 203 is provided on one side of the outer wall of the mounting frame 201. A damper 204 is provided on one side of the outer wall of the mounting frame 201. A mounting bracket 205 is provided on the outer wall of the shock-absorbing spring 203. A screw 206 is provided on the outer wall of the mounting bracket 205. A nut 208 is provided on the outer wall of the screw 206. An installation groove 207 is opened on the outer wall of the mounting bracket 205. A slot 209 is opened at equal intervals on the outer wall of the installation groove 207.

[0020] The outer wall of the mounting frame 201 is threadedly connected to the limiting screws 202. The limiting screws 202 are evenly distributed on the outer wall of the mounting frame 201. The limiting screws 202 are threadedly connected to the valve body 1. The mounting frame 201 and the valve body 1 form a detachable structure through the limiting screws 202. By movably connecting the mounting frame 201 to the outer wall of the valve body 1, and then rotating the limiting screws 202 to thread them into the inside of the valve body 1, the mounting frame 201 is installed and fixed. By setting the limiting screws 202, it is easy to install and remove the mounting frame 201 during use, thereby facilitating the replacement and maintenance of the mounting frame 201 and improving the overall ease of use.

[0021] One side of the outer wall of the mounting frame 201 is connected to one side of the outer wall of the damping spring 203, and the other side of the outer wall of the damping spring 203 is connected to one side of the outer wall of the mounting bracket 205. The damping springs 203 are evenly distributed on one side of the outer wall of the mounting frame 201. The inside of the damping spring 203 is movably connected to the outer wall of the damper 204. One end of the outer wall of the damper 204 is connected to one side of the outer wall of the mounting frame 201, and the other end of the outer wall of the damper 204 is connected to one side of the outer wall of the mounting bracket 205. During operation, vibration caused by temperature changes and medium pressure fluctuations compresses the damping spring 203. The pressure is absorbed by the extension and rebound of the damping spring 203, thereby improving the buffering capacity and reducing the impact of vibration on the valve body 1 and the pipeline, thus maintaining the overall stability of use. The damper 204 is used to prevent the damping spring 203 from shaking continuously.

[0022] The outer wall of the mounting bracket 205 is threadedly connected to the outer wall of the screw 206. The screws 206 are evenly distributed on the outer wall of the mounting bracket 205. The screws 206 and the nuts 208 are threadedly connected. By threading the screws 206 into the inside of the pipe connector, the nuts 208 are then rotated to thread onto the outer wall of the screws 206 to lock them in place.

[0023] A rubber ring 4 is connected to the inner wall of the mounting frame 201. The rubber ring 4 and the mounting frame 201 form an integrated structure. Under the action of the rubber ring 4, the tightness of the connection between the mounting frame 201 and the valve body 1 is improved.

[0024] The slot 209 has a locking block 5 inside, and one end of the outer wall of the locking block 5 is connected to an installation ring 3. The installation ring 3 is movably connected to the installation slot 207. A sealing ring 6 is connected to one side of the outer wall of the installation ring 3. The locking block 5 is locked inside the slot 209, thereby driving the installation ring 3 and the sealing ring 6 to be installed. This improves the tightness of the connection between the mounting bracket 205 and the pipeline, preventing liquid or gas leakage. The locking block 5 facilitates the installation and removal of the sealing ring 6 during use, making it easy to replace and clean the sealing ring 6.

[0025] In use, firstly, the mounting frame 201 is movably connected to the outer wall of the valve body 1. The rubber ring 4 is used to improve the tightness of the connection between the mounting frame 201 and the valve body 1. Then, the limit screw 202 is rotated and threaded into the inside of the valve body 1 to install and fix the mounting frame 201. Then, the locking block 5 is engaged and connected into the inside of the locking groove 209, thereby driving the installation ring 3 and the sealing ring 6 to be installed, improving the tightness of the connection between the mounting bracket 205 and the pipeline. At this time, the valve body 1 is connected to the pipeline. Then, the screw 206 is threaded into the inside of the pipeline connector. Then, the nut 208 is rotated and threaded into the outer wall of the screw 206 to lock it, thereby installing the valve body 1 and the pipeline. During operation, the vibration caused by temperature changes and medium pressure fluctuations compresses the damping spring 203. The pressure is absorbed by the extension and rebound of the damping spring 203, thereby improving a certain buffering capacity. At the same time, the damper 204 is used to prevent the damping spring 203 from shaking continuously.
