Description

Technical Field

[0001] The utility model belongs to the technical field of air supply valves, and in particular relates to a high-precision air supply valve structure. Background Art

[0002] Air supply valves are widely used in industrial smoke exhaust systems. Common application scenarios include factory production workshops, large public places and underground parking lots. These places require large-scale industrial smoke exhaust systems to ensure the quality and safety of indoor air, while controlling the exhaust volume to avoid excessive exhaust gas content.

[0003] The existing air supply valve does not have a mechanism for processing the incoming and outgoing gases. Therefore, during the operation of the air supply valve, the gas will be transported together with the dust particles mixed in the gas, which will cause the environmental quality in the gas input space to deteriorate. For this reason, we have proposed a high-precision air supply valve structure. Utility Model Content

[0004] The purpose of the utility model is to provide a high-precision air supply valve structure to solve the problem that the existing air supply valve proposed in the above background technology has no processing mechanism for the incoming and outgoing gases, so during the operation of the air supply valve, the gas together with the dust particles mixed in the gas will be transported together, which will lead to a decrease in the environmental quality in the gas input space.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-precision air supply valve structure, including an air supply valve body, the air supply valve body including an outer shell, the inner wall of the outer shell is rotatably mounted with two rotating shafts 1, the outer surface of the rotating shaft 1 is fixedly mounted with a wind shield plate, the front and rear side surfaces of the outer shell are both inserted with dust filters, the side surfaces of the dust filter are fixed with a plurality of plug-in plates, the side surfaces of the outer shell are provided with a plurality of slots for the plug-in plates to be inserted, the upper and lower side surfaces of the inner wall of the outer shell are both rotatably mounted with two rotating shafts 2, and a fixed arrangement is arranged between the two rotating shafts 2 that are opposite to each other. A reciprocating screw is provided, a threaded plate is threadedly mounted on the outer surface of the reciprocating screw, a cleaning brush is detachably mounted on the side of the threaded plate, the cleaning brush is fitted on the side of the dust filter, single pulleys are fixedly mounted on the outer surfaces of the two rotating shafts 2 at the upper position, double pulleys are fixedly mounted on the outer surfaces of the top ends of the two rotating shafts 1, belts are drivingly connected between the two double pulleys and between the single pulley and the double pulley at corresponding positions, a motor is fixedly mounted on the upper surface of the outer shell, and the output shaft of the motor is fixedly connected to the top end of the rotating shaft 1 at the corresponding position.

[0006] By adopting the above scheme, a dust filter is set to be used in conjunction with a wind shield. When the wind shield rotates to realize gas transmission, the dust filter can filter the incoming and outgoing gases to prevent dust from being transported together with the gas, thereby achieving a good dust prevention and filtering effect. The dust filter can be conveniently disassembled and assembled through the plug plate and the clamping rod, which is convenient for subsequent disassembly, cleaning and maintenance. A reciprocating screw is set to be used in conjunction with a threaded plate. The rotation of the reciprocating screw can drive the threaded plate to drive the cleaning brush to move up and down synchronously, thereby cleaning the dust filter to prevent the mesh holes of the dust filter from being blocked and ensuring the smooth flow of gas. By using a double pulley and a single pulley in combination, one motor can realize gas transmission and dust filter anti-blocking, thereby reducing the motor investment cost.

[0007] In the above solution, it should be noted that the motor is electrically connected to the external power supply.

[0008] As a preferred embodiment, a card rod is slidably installed in the plug board, an operating plate is fixedly installed on one end of the card rod, a spring is fixedly installed between the operating plate and the plug board, and a card groove for the card rod to be inserted into is opened on the inner wall of the slot.

[0009] By adopting the above solution, the force generated by the deformation of the spring is used to drive the clamping rod into the clamping slot, so as to lock the plug plate and further lock the dust filter.

[0010] As a preferred implementation, a mounting groove is provided on the outer surface of the dust filter, and a sealing ring is pasted in the mounting groove.

[0011] With the above solution, the provision of the sealing ring can ensure good sealing between the dust filter and the outer shell.

[0012] As a preferred embodiment, a plurality of guide rods are fixedly mounted on the inner wall of the outer shell, and the threaded plate is slidably mounted on the outer surfaces of the plurality of guide rods.

[0013] By adopting the above solution, the setting of the guide rod can support the up and down movement of the threaded plate and improve the movement stability.

[0014] As a preferred embodiment, a plurality of connecting blocks are fixedly mounted on the side of the cleaning brush, connecting bolts are threadedly mounted on the connecting blocks, and connecting thread grooves for screwing the connecting bolts are provided on the surface of the threaded plate.

[0015] By adopting the above scheme, the connecting block is used in conjunction with the connecting bolts, so that the disassembly and assembly operation of the cleaning brush is convenient.

[0016] As a preferred embodiment, sealing pads are adhered to the outer surfaces of the two windshields.

[0017] By adopting the above solution, the provision of the sealing pad can ensure that the wind shield is in a good sealing state when it is closed.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The high-precision air supply valve structure is used in conjunction with the wind shield by setting a dust filter. When the wind shield rotates to realize gas transmission, the dust filter can filter the inlet and outlet gas to prevent dust from being transported together with the gas, which has a good dust prevention and dust filtering effect. The dust filter can be conveniently disassembled and assembled through the plug plate and the clamp rod, which is convenient for subsequent disassembly, cleaning and maintenance.

[0020] The high-precision air supply valve structure is used by setting a reciprocating screw in conjunction with a threaded plate. The rotation of the reciprocating screw can drive the threaded plate to drive the cleaning brush to move up and down synchronously, thereby cleaning the dust filter to avoid clogging of the mesh of the dust filter and ensure the smooth flow of gas. By using a double pulley and a single pulley in combination, one motor can achieve gas delivery and dust filter anti-blocking, reducing the motor investment cost. BRIEF DESCRIPTION OF THE DRAWINGS
