Description

Technical Field

[0001] The invention relates to the technical field of air volume regulating valves, in particular to an air volume regulating valve with regulating and locking functions. Background Art

[0002] The air volume regulating valve, also known as the damper, is an indispensable central air-conditioning terminal accessory in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings. It is generally used in air-conditioning and ventilation system pipes to adjust the air volume of the branch pipes. It can also be used for the mixing and adjustment of fresh air and return air.

[0003] However, in the existing technology, a baffle is simply set inside the existing air volume regulating valve, and the air flow volume inside the air volume regulating valve is controlled by rotating the baffle. However, the air flow volume will generate thrust on the baffle inside the air volume regulating valve. If the baffle inside the air volume regulating valve is not locked, the pitch angle of the baffle inside the air volume regulating valve will be deflected, so the circulation of air volume cannot be controlled. At the same time, the baffle inside the air volume regulating valve has no auxiliary function of purifying the air, and cannot purify the air according to environmental needs.

[0004] Therefore, we need an air volume regulating valve with an adjustment and locking function to solve the problem of locking the pitch angle of the baffle inside the existing air volume regulating valve, and also to change the air flow rate by adjusting the angle of the baffle inside the air volume regulating valve.

[0010] Preferably, a circular groove is provided on the side surface of the baffle, a fixed gear ring is provided inside the circular groove, the inner ring surface of the fixed gear ring is fixedly connected to the outer surface of the fixed shaft, the teeth of the fixed gear ring mesh with the teeth of the driving gear, the inner surface of the driving gear is fixedly connected to the end of the power output shaft of the servo motor, the base of the servo motor is fixedly connected to the surface of the mounting groove, the mounting groove is provided on the side surface of the baffle, and the circular groove and the mounting groove are communicated.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The air volume regulating valve with adjusting and locking function proposed by the present invention purifies the air circulating inside the shell through the filter. At the same time, when there is no need to purify the air circulating inside the shell, the plane of the baffle surface without the filter is rotated, and the elastic force of the rubber gasket allows the rubber sealing strip to rest against the inner surface of the shell, thereby sealing the air volume inside the shell controlled by the baffle.

Therefore, when the baffle 2 rotates inside the shell 1, the elastic force of the rubber gasket 10 allows the rubber sealing strip 6 to press against the inner surface of the shell 1, thereby playing a sealing role for the baffle 2 to control the air volume inside the shell 1. Embodiment 4

[0023] See attached Figure 1-9 On the basis of the third embodiment, in order to realize automatic control of the air volume flowing inside the housing 1 according to the rotation pitch angle of the baffle 2, a circular slot 7 is provided on the side surface of the baffle 2, and a fixed gear ring 8 is provided inside the circular slot 7.

Therefore, the rotation of the driving gear 16 allows the baffle 2 to make a circular motion along the fixed shaft 5, thereby realizing that the baffle 2 can automatically rotate inside the shell 1, thereby automatically controlling the circulating air volume inside the shell 1 according to the rotation pitch angle of the baffle 2. Embodiment 5

[0024] See attached Figure 1-9 On the basis of the fourth embodiment, in order to realize that the baffle 2 is firmly locked on the surface of the fixed shaft 5 and cannot rotate, a locking slot 17 is opened on the surface of the fixed shaft 5, and a locking plug 18 is inserted on the surface of the locking slot 17. The outer surface of the locking plug 18 is fixedly connected to the end of the power output shaft of the micro electric push rod 19, and the base of the micro electric push rod 19 is fixedly connected to the surface of the mounting slot 13; By fixing the end of the power output shaft of the micro electric push rod 19 to the surface of the locking plug 18, and then opening a locking slot 17 on the surface of the fixed shaft 5, when the automatic micro electric push rod 19 is used, the surface of the locking plug 18 is inserted into the surface of the locking slot 17, so that the baffle 2 is firmly locked on the surface of the fixed shaft 5 and cannot rotate.

The plane is rotated, the end of the fixing pin 12 is fixedly connected to the surface of the arc-shaped slot 9, and then the surface of the fixing pin 12 is rotated to connect the internal through hole of the lock buckle 11. When the knob locks the lock buckle 11, the filter 4 is firmly locked inside the through port 3 to prevent the filter 4 from falling off from the surface of the baffle 2 when the airflow inside the housing 1 is vented. At the same time, the filter 4 can be removed from the surface of the baffle 2 according to the season. The fixing pin 12 is set in a "T" shape to limit the lock buckle 11, and then the tension of the arc-shaped slot 9 supports the lock buckle 11 to prevent slipping. The top surface of the limiting support rod 20 is fixedly connected to the rubber sealing strip 6 The bottom surface of the limit support rod 20 is then movably connected to the surface of the arc groove 9, and a rubber gasket 10 is arranged inside the arc groove 9. Therefore, when the baffle 2 rotates inside the housing 1, the rubber sealing strip 6 can be pressed against the inner surface of the housing 1 by the elastic force of the rubber gasket 10, so that the baffle 2 controls the air volume inside the housing 1 to seal the baffle 2.

Therefore, the rotation of the driving gear 16 causes The baffle 2 can make a circular motion along the fixed axis 5, so that the baffle 2 can automatically rotate inside the shell 1, so as to automatically control the air volume circulating inside the shell 1 according to the rotation pitch angle of the baffle 2, by fixing the end of the power output shaft of the micro-electric push rod 19 to the surface of the locking plug 18, and then opening a locking slot 17 on the surface of the fixed axis 5, when the automatic micro-electric push rod 19 makes the surface of the locking plug 18 plug into the surface of the locking slot 17, the baffle 2 is firmly locked on the surface of the fixed axis 5 and cannot rotate. When the rotation pitch angle of the baffle 2 is locked, the air volume circulating inside the shell 1 is controlled.
