Abstract
The invention discloses a gear transmission air quantity regulating valve which comprises a valve body and regulating blades arranged in an air port of the valve body, wherein one end of a transmission shaft of each regulating blade penetrates through the valve body and is connected with a driving device on the outer surface of the valve body, the upper side and the lower side of the air port of the valve body are respectively hinged with a baffle plate for blocking the regulating blade, the valve body comprises a U-shaped hollow body and a closed body arranged at the opening of the hollow body, an air outlet hole is formed in the inner side of the hollow body, an air inlet is formed in the center of the outer side of the hollow body, and the driving device is arranged on the closed body. According to the gear transmission air volume adjusting valve, the hinged baffle can rotate, when the baffle rotates to be horizontal to the valve body, the adjusting blade can be blocked, so that the adjusting blade can be kept to be tightly closed under the compression of larger air pressure, and a better sealing effect is achieved.
Description
Technical Field
The invention relates to the field of air volume adjusting devices, in particular to a gear transmission air volume adjusting valve.
Background
The air volume regulating valve controls the air volume by the opening and closing angle of the valve blade, controls the air volume by regulating the opening and closing angle of the blade, is an indispensable central air-conditioning terminal fitting in ventilation, air conditioning and air purification engineering of industrial factory building civil buildings, is generally used in air conditioners and ventilation system pipelines, is used for regulating the air volume of branch pipes, and can also be used for mixed regulation of fresh air and return air. The gear transmission air volume adjusting valve has two types, namely a mechanical type and an electric control type, wherein the gear transmission air volume adjusting valve is one of the mechanical types, and an operator needs to twist the worm according to experience to adjust the opening degree of the blade.
However, the existing gear transmission air volume adjusting valve is complex to disassemble and assemble, is not beneficial to blade cleaning, and is easy to cause air pollution; and current gear drive air regulation valve receives great atmospheric pressure effect when closing, oppresses the blade and rotates for gas passes the gap of blade, does not reach fine result of use.
Disclosure of Invention
In view of this, the invention provides a gear transmission air volume adjusting valve which has the characteristics of easy cleaning and convenient use.
The invention solves the problems through the following technical means:
the invention discloses a gear transmission air volume adjusting valve, which comprises a valve body and an adjusting blade arranged in an air port of the valve body, wherein one end of a transmission shaft of the adjusting blade penetrates through the valve body and is connected with a driving device on the outer surface of the valve body, and the gear transmission air volume adjusting valve is characterized in that: the upper side and the lower side of the air inlet of the valve body are respectively hinged with a baffle plate used for blocking the adjusting blade, the valve body comprises a U-shaped hollow body and a closing body arranged at the opening of the hollow body, an air outlet hole is formed in the inner side of the hollow body, the center of the outer side of the hollow body is provided with an air inlet, and the driving device is installed on the closing body.
Furthermore, the driving device is a worm and gear adjusting mechanism, and the transmission shaft is fixedly connected with a worm wheel.
Further, the opening and closing angle of the adjusting blade is 90 degrees.
Furthermore, the top of one end of the transmission shaft connected with the driving device is also provided with a pointer.
According to the gear transmission air volume adjusting valve, the hinged baffle can rotate, when the baffle rotates to be horizontal to the valve body, the adjusting blade can be blocked, so that the adjusting blade can be kept to be tightly closed under the compression of a larger air pressure, and a better sealing effect is achieved; when the baffle rotates to be vertical to the valve body, the adjusting blade can be adjusted at will, so that the valve is convenient to use; the air inlet can blow air into the hollow body, and then the air is blown out from the air outlet, so that dust on the surface of the adjusting blade can be blown off, and the cleaning is convenient.
