Description

Technical Field

[0001] The utility model belongs to the technical field of temperature reduction and pressure reduction devices, and particularly relates to a welding type temperature reduction and pressure reduction device. Background Art

[0002] The temperature and pressure reduction device is a steam thermal energy parameter (pressure, temperature) conversion device and energy-saving device that utilizes waste heat, which is widely used in thermal energy projects in modern industry such as cogeneration, centralized heating (or steam supply) and light industry, electric power, chemical industry, textile and other enterprises. Through this device, the steam parameters provided by the user are reduced to the appropriate temperature and pressure required by the user to meet the user's requirements, and it can fully save thermal energy and use thermal energy reasonably.

[0003] During the operation of the temperature reduction and pressure reduction device, certain vibrations will be generated. Long-term large vibration amplitude may affect the connectivity between the steam pipe and the temperature reduction and pressure reduction valve. Usually, a damper is used to reduce the vibration of the temperature reduction and pressure reduction device. The damper is usually directly installed at the bottom of the temperature reduction and pressure reduction device for vibration reduction. Since there is no support for the temperature reduction and pressure reduction device, the damper has to support the temperature reduction and pressure reduction device when it is not in use, which can easily cause metal fatigue of the damper, thereby affecting the vibration reduction effect and service life of the damper. Utility Model Content

[0004] The purpose of the utility model is to provide a welded temperature reduction and pressure reduction device. By setting a support component, specifically by moving a sliding rod to fit with the top of the inner wall of the connecting block and applying an upward pushing force, the pressure reduction and temperature reduction device can be supported. The damper does not need to bear the entire weight of the pressure reduction and temperature reduction device, thereby reducing the impact of metal fatigue on the damper, thereby improving the service life of the damper, and solving the problem that the existing damper is usually directly installed at the bottom of the temperature reduction and pressure reduction device for shock absorption. Since the temperature reduction and pressure reduction device is not supported, the damper still needs to support the temperature reduction and pressure reduction device when the temperature reduction and pressure reduction device is not in use, which can easily cause metal fatigue of the damper, thereby affecting the shock absorption effect and service life of the damper.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a welded temperature and pressure reduction device, comprising a shock-absorbing box and a pressure reduction and temperature reduction device, wherein a cavity is provided inside the shock-absorbing box, a sliding plate is slidably connected to the inner wall of the cavity, the bottom of the pressure reduction and temperature reduction device is fixedly connected to the top of the sliding plate, a plurality of sliding holes are provided inside the sliding plate, the inner wall of the sliding hole is slidably connected to a limiting rod, the bottom of the limiting rod is fixedly connected to the bottom of the inner wall of the cavity, a plurality of supporting columns are fixedly connected to the bottom of the cavity, a damper is fixedly connected to the top of the supporting column, the top of the damper is fixedly connected to the bottom of the sliding plate, a pushing component is arranged at the bottom of the inner wall of the cavity, the pushing component comprises a rotating disk, a rotating rod is fixedly connected to the bottom of the rotating disk, and a supporting component is arranged at the bottom of the sliding plate;

[0007] There are two support assemblies, and the two support assemblies are symmetrically arranged with the rotating disk as the center. The parts contained in the two support assemblies are the same. The support assembly includes a connecting block, and the front and back sides of the connecting block are fixedly connected to connecting plates, and the top of the connecting plate is fixedly connected to the bottom of the sliding plate. The inner wall of the connecting block is provided with a second sliding hole, and the inner wall of the second sliding hole is slidably connected to a sliding rod, and the bottom of the sliding rod is fixedly connected to the support block. By setting the support assembly, specifically by moving the sliding rod to fit with the top of the inner wall of the connecting block and applying an upward pushing force, the pressure reducing and cooling device can be supported, and the damper does not need to bear the entire weight of the pressure reducing and cooling device, thereby reducing the impact of metal fatigue on the damper, thereby improving the service life of the damper and saving costs.

[0008] Furthermore, the left and right sides of the support block are both inclined, and a spring is sleeved on the outer surface of the sliding rod. The bottom of the spring is fixedly connected to the top of the support block, and the top of the spring is fixedly connected to the bottom of the connecting block. When the support block moves close to the connecting block, the spring will be squeezed. When the squeezing force disappears, the rebound force of the spring will quickly bounce the support block back. The inclined surface setting can make another inclined surface lift the support block.

[0009] Furthermore, a sliding hole three is opened on the right side of the support block, and the inner wall of the sliding hole three is slidably connected to a limiting rod two, the top of the limiting rod two is fixedly connected to the bottom of the sliding plate, and a rotating hole is opened at the bottom of the cavity. When the support block moves, the support block is limited by the limiting rod two, so that the support block will not rotate and can only move horizontally, and the direction of the inclined surface will not be changed, thereby not affecting the contact with the inclined surface.

[0010] Furthermore, the outer surface of the rotating rod is rotatably connected to the inner wall of the rotating hole, the bottom of the shock absorber box is fixedly connected to a motor, the top output end of the motor is fixedly connected to the bottom of the rotating rod, and the top of the rotating disk is fixedly connected to two connecting shafts, and the rotating rod rotates in the rotating hole, thereby driving the rotating disk to rotate together, and when the rotating disk rotates, the connecting shaft at the top is moved, thereby changing the angle of the connecting rod, so that the connecting rod can push the pushing block.

[0011] Furthermore, two connecting rods are provided on the top of the rotating disk, and a connecting hole is opened on one side of the two connecting rods close to the rotating disk. The outer surface of the connecting shaft is rotatably connected to the inner wall of the connecting hole, and two pushing blocks are provided at the bottom of the inner wall of the cavity. The bottoms of the two pushing blocks are slidably connected with slide rails, and the bottoms of the slide rails are fixedly connected to the bottom of the inner wall of the cavity. By setting a pushing component, specifically by starting a motor to drive the rotating disk to rotate, the connecting rod pushes the pushing block to lift the support block. By controlling the rise and fall of the support block, the pressure reducing and temperature reducing device can be supported when it is not working, and can also fall when the pressure reducing and temperature reducing device is working, without affecting the shock absorbing effect of the damper.

[0012] Furthermore, a second connecting shaft is fixedly connected to the top of the two pushing blocks, and a second connecting hole is opened on the side of the two connecting rods close to the pushing blocks. Through the cooperation of the second connecting shaft and the second connecting hole, the inner wall of the second connecting hole is rotatably connected to the outer surface of the second connecting shaft. The side of the two pushing blocks away from the rotating disk is set with an inclined surface. By rotating, the connecting rod can change its own angle when the rotating disk rotates, thereby pushing the pushing block. Through the contact and cooperation between the inclined surface of the pushing block and the inclined surface of the supporting block, the supporting block can be lifted up to make the supporting block rise, and the support block will be lowered after separation.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model provides a support assembly, specifically, by moving the sliding rod to fit the top of the inner wall of the connecting block and applying an upward thrust, so that the pressure reducing and temperature reducing device can be supported. The damper does not need to bear the entire weight of the pressure reducing and temperature reducing device, thereby reducing the impact of metal fatigue on the damper, thereby improving the service life of the damper and saving costs.

[0015] 2. The utility model sets a pushing component, specifically, starts the motor to drive the rotating disk to rotate, so that the connecting rod pushes the pushing block to lift the supporting block. By controlling the rise and fall of the supporting block, the pressure reducing and temperature reducing device can be supported when not working, and can also be dropped when the pressure reducing and temperature reducing device is working, which will not affect the shock absorbing effect of the damper.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] There are two support assemblies 3, and the two support assemblies 3 are symmetrically arranged with the rotating disk 131 as the center. The parts contained in the two support assemblies 3 are the same. The support assembly 3 includes a connecting block 31, and the front and back sides of the connecting block 31 are fixedly connected to connecting plates 35, and the top of the connecting plate 35 is fixedly connected to the bottom of the sliding plate 11. A sliding hole 2 is opened on the inner wall of the connecting block 31, and a sliding rod 33 is slidably connected to the inner wall of the sliding hole 2, and the bottom of the sliding rod 33 is fixedly connected to the support block 32. By setting the support assembly 3, specifically by moving the sliding rod 33 to fit with the top of the inner wall of the connecting block 31 and applying a pushing force upward, the pressure reducing and cooling device 2 can be supported, and the damper 121 does not need to bear the entire weight of the pressure reducing and cooling device 2, thereby reducing the influence of metal fatigue on the damper 121, thereby improving the service life of the damper 121 and saving costs.

[0029] The left and right sides of the support block 32 are both inclined, and a spring 34 is sleeved on the outer surface of the sliding rod 33. The bottom of the spring 34 is fixedly connected to the top of the support block 32, and the top of the spring 34 is fixedly connected to the bottom of the connecting block 31.

[0030] A sliding hole 3 is provided on the right side of the support block 32, and a limiting rod 2 36 is slidably connected to the inner wall of the sliding hole 3.

A pushing component 13 is arranged, and specifically, the rotating disk 131 is driven to rotate by starting the motor 14, so that the connecting rod 132 pushes the pushing block 133 to lift the support block 32.

[0036] A specific application of this embodiment is:

[0037] When in use, when the pressure reducing and temperature reducing device 2 is working and vibrates, it will drive the sliding plate 11 to move back and forth up and down, and the vibration is reduced by the damper 121 at the bottom of the sliding plate 11, thereby reducing the influence of the connectivity between the steam pipe and the temperature reducing and pressure reducing valve. When the pressure reducing and temperature reducing device 2 stops working, the rotating rod 134 is driven to rotate counterclockwise by starting the motor 14 to rotate the rotating disk 131. When the rotating disk 131 rotates, the inner walls of the connecting hole 1 and the connecting hole 2 inside the connecting rod 132 will rotate on the surface of the connecting shaft 1 at the top of the rotating disk 131 and the surface of the connecting shaft 2 at the top of the pushing block 133 respectively. When the rotating disk 131 rotates and drives the connecting shaft 1 close to the pushing block 133, the connecting rod 132 will push the pushing block 133 to slide on the surface of the slide rail 15, so that the pushing block 133 is close to the supporting block 32. Since the side of the pushing block 133 away from the rotating disk 131 is an inclined surface, and the left and right sides of the supporting block 32 are both inclined surfaces, the supporting block 32 will be The push block 133 is pushed up, driving the sliding rod 33 to slide on the inner wall of the connecting block 31. When the supporting block 32 approaches the connecting block 31, the spring 34 is squeezed until the sliding rod 33 moves to fit the top of the inner wall of the connecting block 31, and a pushing force is applied upward to support the decompression and temperature reduction device 2. The damper 121 does not need to bear the entire weight of the decompression and temperature reduction device 2, thereby reducing the influence of metal fatigue on the damper 121, thereby improving the service life of the damper 121. When the decompression and temperature reduction device 2 needs to work, the motor 14 is started to drive the rotating rod 134 to rotate clockwise, so that the connecting rod 132 pulls the pushing block 133 away from the supporting block 32, cancels the support for the supporting block 32, and is rebounded by the rebound force of the spring 34 to make the supporting block 32 fall, driving the sliding rod 33 to fall. There is a gap between the sliding rod 33 and the inner wall of the connecting block 31, and the damping effect of the damper 121 will not be affected due to excessive tight fit.
