Description

Technical Field

[0001] The utility model relates to the technical field of regulating valves, in particular to a novel thermal insulation split multi-leaf regulating valve. Background Art

[0002] The double-leaf multi-leaf regulating valve is an indispensable system accessory in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings. It is often used in air conditioning and ventilation system pipes to adjust the air volume of the main pipe and its branches. It is also often used for the mixed adjustment of fresh air and return air. The performance requirements for the regulating valve vary depending on the area of ​​use. In the extremely cold northern regions, the regulating valve needs to be insulated. At present, the existing insulation treatment method for regulating valves is to paste insulation materials on the valve plate and the valve body to play a role in insulating the air and the valve itself. The pasting of the valve plate will cause hidden dangers in the multi-leaf linkage structure, resulting in poor sealing performance of the regulating valve. In some cases where the air valve of the air conditioning and ventilation system needs to be tightly closed, such as in the extremely cold northern regions, when it is necessary to block the cold air from the outside, if the air valve has poor sealing performance, it may cause an increase in indoor heat energy consumption. In severe cases, it may cause the valve body to freeze and fail to operate;

[0003] In the prior art, for example, announcement number CN214534550U proposes a new type of insulated split multi-leaf regulating valve. The present technical solution relates to a new type of insulated split multi-leaf regulating valve. At present, the existing insulation treatment method for regulating valves is to stick insulation materials on the valve plate and the valve body to play an insulation role for the air and the valve itself. The sticking of the valve plate will cause hidden dangers in the multi-leaf linkage structure, resulting in poor sealing performance of the regulating valve. A new type of insulated split multi-leaf regulating valve, which comprises: a valve body and valve leaves, a group of valve leaves are installed in the valve body, one side of the valve leaf is connected to an insulation groove plate with a U-shaped cross-section, an insulation layer is installed between the upper and lower insulation groove plates, the top and bottom of the valve body are respectively connected to the upper and lower insulation sealing strips of the valve body, a valve leaf insulation sealing strip is connected between two adjacent valve leaves, and the two ends of the valve body are connected to insulation sealing strips on both sides of the valve body. The utility model is applied to the field of ventilation and air conditioning;

[0004] However, most of the existing thermal insulation split multi-leaf regulating valves are provided with filter plates, and the filter plates are mostly installed on the housing by multiple sets of screws. When the filter plate is damaged and needs to be replaced, the staff needs to use tools to remove the multiple sets of screws before replacing the filter plate, which is troublesome and increases the work intensity of the staff;

[0005] In order to solve the above problems, this application proposes a new type of thermal insulation split multi-leaf regulating valve. Utility Model Content

[0006] The utility model is intended to provide a novel insulated split multi-leaf regulating valve, which is mainly used to solve the problem that the internal filter plates of the existing split multi-leaf regulating valves are mostly installed on the shell by multiple sets of screws, which makes it troublesome for the staff to disassemble and replace the filter plates.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A novel insulated double-leaf regulating valve comprises a valve body, a rectangular groove is provided on the top of the valve body, a frame is inserted into the inside of the rectangular groove, a filter layer is fixedly connected to the inner wall of the frame, a symmetrical clamping block is fixedly connected to the top of the inner wall of the valve body, and the two clamping blocks are matched with the frame, a symmetrical fixed block is fixedly connected to the bottom of the valve body, a first sliding cavity is provided on one side of the fixed block, a moving block is slidably connected to the inside of the first sliding cavity, the fixed block extends from one side of the moving block, and a symmetrical first spring is fixedly connected to the other side, the other end of the first spring is fixedly connected to the inner wall of the first sliding cavity, and a limiting component is provided on one end of the moving block close to the fixed block.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When the device is in use, when there is too much dust inside the filter layer on the frame or it is damaged, the staff needs to disassemble the frame to clean or replace the filter layer. By pushing the moving block in the direction of the fixed block, when the moving block is away from the frame, the moving block will be better fixed under the action of the limiting component, so that people can easily disassemble the frame. When installing the frame, insert the frame into the valve body through the rectangular groove. When the frame completely enters the valve body, the moving block can pop out under the action of the first spring in the first sliding cavity, so as to better limit the frame. The new thermal insulation double-leaf regulating valve can be used normally.

[0011] 2. Beneficial effects: The frame arranged inside the valve body has a filter layer arranged on the inner wall of the frame, which can filter the airflow better. After the frame is installed inside the valve body, the movable block can pop out and resist the frame under the action of the first spring inside the first sliding cavity, which can fix the frame better. When it needs to be disassembled, the movable block only needs to be pushed into the first sliding cavity to move it away from the frame to disassemble the frame. This not only makes the installation of the frame inside the valve body more stable, but also makes the disassembly of the frame more convenient, thereby making it convenient for people to clean or replace the filter layer inside the frame.

[0012] Preferably, the limiting assembly includes a second sliding cavity provided at one end of both sides of the moving block close to the fixed block, the inside of the second sliding cavity is slidably connected with an insert block, one side of the inner wall of the second sliding cavity is fixedly connected with a second spring, the other end of the second spring is fixedly connected to the insert block, the inner wall of the first sliding cavity is provided with a slot matching the insert block, the inside of the slot is slidably connected with a push rod, one end of the push rod extends out of the fixed block, and the other end is set to abut against the insert block. When the frame is disassembled, the moving block is pushed into the first sliding cavity to move it away from the frame. When the moving block moves to a certain extent, the insert blocks on both sides of the moving block will pop out and engage with the slot under the action of the second spring, which can play a good limiting role on the moving block, thereby facilitating people to disassemble the frame. After the frame is installed inside the valve body, the push rods on both sides of the fixed block are pressed at the same time to push the insert block to move into the second sliding cavity. When the insert block is out of the slot, the moving block can be popped out and abut against the frame under the action of the first spring inside the first sliding cavity, which can play a good fixing role on the frame. The advantage of such a setting is that it can make it more convenient for people to disassemble the frame.

[0013] Preferably, the filter layer includes filter screens fixedly connected at both ends of the inner wall of the frame, and an activated carbon layer fixedly connected to the inner wall of the frame between the two filter screens. Large particle impurities in the gas can be filtered through the filter screens arranged at both ends of the inner wall of the frame, and small particle impurities in the gas can be filtered through the activated carbon layer arranged inside the frame, thereby enabling the new thermal insulation double-leaf multi-leaf regulating valve to have a better filtering effect on the airflow.

[0014] Preferably, a T-block is fixedly connected to one end of the top of the moving block close to the fixed block, and a T-slot matching the T-block is provided at the bottom of the valve body. During the sliding process of the moving block inside the second sliding cavity, the T-block arranged on the top of the moving block and the T-slot provided at the bottom of the valve body can play a better limiting and guiding role for the moving block, which not only makes the moving block more stable when sliding inside the second sliding cavity, but also effectively prevents the moving block from escaping from the second sliding cavity.

[0015] Preferably, a symmetrical slider is fixedly connected to the outer wall of the push rod, and a sliding groove matching the slider is provided on the inner wall of the slot. When the push rod slides inside the slot, the slider provided on the outer wall of the push rod and the sliding groove provided on the inner wall of the slot can not only make the push rod more stable when sliding inside the slot, but also effectively prevent the push rod from detaching from the slot, thereby effectively ensuring the normal use of the device.

[0016] Preferably, the top of the T-shaped block is rotatably connected to a plurality of ball bearings, and the ball bearings are equidistantly distributed in a linear array on the top of the T-shaped block. When the moving block slides on the bottom of the valve body, the T-shaped block will slide inside the T-shaped slot. The plurality of ball bearings rotatably connected to the top of the T-shaped block can effectively reduce the friction between the T-shaped block and the inner wall of the T-shaped slot, thereby making the moving block move more smoothly.

[0017] Preferably, a button is fixedly connected to the center of the bottom of the frame, and the corners of the button are all rounded, so that the frame can be pulled out of the valve body more easily by pulling the button, thereby making the disassembly of the frame more convenient. By setting the corners of the button to be rounded, people can hold the button and pull it more comfortably. BRIEF DESCRIPTION OF THE DRAWINGS
