Description

Technical Field

[0001] This utility model relates to the field of pressure regulation technology, and in particular to a pressure regulation mechanism. Background Technology

[0002] Pressure regulating mechanisms are typically used to regulate the internal pressure of equipment. These mechanisms can prevent excessively high internal pressure from causing overpressure risks or excessively low pressure from affecting reaction efficiency.

[0003] When operators need to adjust the pressure of the equipment, they control the pressure regulating mechanism to adjust the pressure inside the reactor. However, during use, existing pressure regulating mechanisms are susceptible to environmental influences, causing air carrying moisture or dust to enter the mechanism through the air inlet. This shortens the lifespan of the pressure regulating mechanism, hinders the reaction, and reduces reaction efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of "shortened service life and reduced reaction efficiency of pressure regulating mechanism" in the prior art, and to propose a pressure regulating mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressure regulating mechanism, comprising a pressure regulating driver, a driving shaft at the driving end of the pressure regulating driver, an air nozzle at the outer side of the pressure regulating driver, a filter device at the air inlet end of the air nozzle, the filter device comprising an extension sleeve, a connecting ring at one end of the extension sleeve being threadedly connected to the surface of the air nozzle, a storage sleeve at the other end of the extension sleeve, a sponge block inside the storage sleeve, a limit cover threadedly connected to the air inlet end of the storage sleeve, an air inlet on the surface of the limit cover, a heating component inside the extension sleeve, the heating component comprising an air chamber and a heating wire, the sponge block adsorbing dust in the air through its porous structure and trapping or adsorbing moisture through its pores, thereby achieving the blocking of moisture and dust, the air chamber inside the extension sleeve communicating with the interior of the storage sleeve, the air chamber cooperating with the storage sleeve to guide gas flow.

[0006] Preferably, a heating wire is fixedly connected inside the extension sleeve, and the heating wire is located inside the air cavity to heat the air.

[0007] Preferably, the surface of the extension sleeve is provided with a disassembly device, the disassembly device is fixedly connected to the air nozzle, and the disassembly device includes a positioning sleeve, which is detachably connected to the extension sleeve.

[0008] Preferably, a positioning hole is provided on the surface of one end of the extension sleeve, and the positioning hole is located on the inside of the positioning sleeve.

[0009] Preferably, a metal block is fixedly connected to the surface of the positioning sleeve, and a magnetic pin is inserted into the inside of the metal block. The magnetic pin is inserted into the inside of the positioning hole, one end of the magnetic pin is connected to the positioning hole, and the other end of the magnetic pin is magnetically connected to the surface of the metal block. The magnetic pin can cooperate with the metal block to prevent the magnetic pin from disengaging from the positioning hole.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting a filter device, when the worker needs to filter the air, the worker installs the extension sleeve on the air nozzle. When the pressure regulating actuator is working, the pressure regulating actuator draws air from the outside. The air enters through the air inlet of the limiting cover and comes into contact with the sponge block. The air carrying moisture and dust is blocked by the sponge block. The sponge block adsorbs dust in the air through its porous structure and uses its pores to trap or adsorb water vapor, thereby blocking moisture and dust. The air enters the cavity inside the extension sleeve. The worker judges whether to turn on the heating wire to heat the air based on the environment. The air enters the interior of the pressure regulating actuator through the air nozzle. By setting a filter device, the worker can effectively filter the air and prevent air carrying moisture or dust from entering the interior of the pressure regulating mechanism from the air nozzle, thereby improving the service life of the pressure regulating mechanism and increasing the reaction efficiency.

[0012] 2. In this utility model, by setting a disassembly device, when the worker needs to maintain the filter component, the worker pulls the magnetic pin, the magnetic pin disengages from the positioning hole, the worker first loosens the extension sleeve from the air nozzle, and then pulls the extension sleeve away from the positioning sleeve. By setting a disassembly device, it is possible to effectively facilitate the worker to maintain the filter component, avoid inconvenience when the worker maintains the filter component, and thus improve the worker's work efficiency.

The sponge block 33 adsorbs dust in the air through its porous structure and uses its pores to trap or adsorb water vapor, thereby achieving the blocking of moisture and dust.

[0022] Specifically, the extension sleeve 36 has an air cavity 35 inside, which is connected to the inside of the storage sleeve 34. The air cavity 35 can cooperate with the storage sleeve 34 to guide the flow of gas.

[0023] Specifically, a heating wire 37 is fixedly connected inside the extension sleeve 36. The heating wire 37 is located inside the air cavity 35 to achieve the purpose of heating the air.
