Description

Technical Field

[0001] This utility model belongs to the field of air valve technology, specifically relating to a corrosion-resistant air valve. Background Technology

[0002] Air volume regulating valves (or simply air valves) are indispensable central air conditioning terminal accessories in ventilation, air conditioning, and air purification projects in industrial plants and civil buildings. They are generally used on air conditioning and ventilation system ducts to regulate the air volume of branch pipes. Air valves are typically adjusted by a handle. To maintain the valve opening even when the air pressure is unstable, a locking mechanism is usually added to the adjusting handle.

[0003] Currently, most existing air valves use positioning bolts to fix the rotation angle of the actuator handle. The back-and-forth turning of these positioning bolts makes operation inconvenient and fails to quickly lock the actuator handle in place. Therefore, a corrosion-resistant air valve is proposed to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a corrosion-resistant air valve for existing devices, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a corrosion-resistant air valve, including a valve body, a fixed frame fixedly connected to the valve body, a valve stem rotatably connected to the fixed frame via a bearing, a valve plate fixedly connected to the valve stem, and an actuator provided on the valve stem;

[0006] The actuator includes an actuator handle and a toothed plate. A fixed plate is fixedly connected to the actuator handle, and a grip is provided on the fixed plate. A connecting post is fixedly connected to the bottom of the grip, and a positioning toothed plate is fixedly connected to the lower end of the connecting post. A spring is sleeved on the connecting post, and a guide post is fixedly connected to the grip. The positioning toothed plate meshes with the toothed plate. A guide hole is provided on the actuator handle, and the guide post passes through the interior of the guide hole. When the air valve needs to be adjusted, the operator can hold the actuator handle and the grip. As the operator increases the grip strength, the grip will move closer to the actuator handle under the action of the grip strength. The movement of the grip will drive the positioning toothed plate to move upward. At this time, the actuator handle loses the positioning of the positioning toothed plate, and the operator can push the actuator handle to control the opening and closing state of the valve plate. After the adjustment is completed, the operator releases the actuator handle. At this time, the positioning toothed plate moves downward under the action of the spring, so that the positioning toothed plate meshes with the toothed plate, achieving the purpose of locking the actuator handle. The operation is simple and can quickly lock the actuator handle of the air valve.

[0007] This utility model further illustrates that the actuator handle is fixedly connected to the valve stem, the fixing plate has a through hole, the guide post passes through the interior of the through hole, and the positioning tooth plate is fixedly connected to a limit rod. The guide post can guide the handle.

[0008] The present invention further explains that the lower end of the spring abuts against the positioning tooth plate, the upper end of the spring abuts against the bottom of the fixed plate, and a limiting block is fixedly connected to the limiting rod. The limiting block can prevent the limiting rod from detaching from the fixed plate, and the spring can generate a pushing force on the positioning tooth plate, so that the positioning tooth plate can mesh with the tooth plate.

[0009] This utility model further explains that the toothed plate is fixedly connected to the fixing frame, and a limiting hole is provided on the fixing plate. The upper end of the limiting rod passes through the interior of the limiting hole. The limiting rod can limit the positioning toothed plate and prevent the positioning toothed plate from shifting position.

[0010] This utility model further illustrates that a scale block is fixedly connected to the actuator handle, a scale plate is fixedly connected to the mounting bracket, and a connecting flange is fixedly connected to the valve body. The setting of the scale block and the scale plate makes it convenient for operators to control the opening and closing of the air valve.

[0011] This utility model further illustrates that the valve body is provided with a filtering mechanism, the filtering mechanism includes a fixing ring, a filter ring is fixedly connected to the fixing ring, a filter screen is fixedly connected inside the filter ring, the filter ring is inserted into the air inlet of the valve body, and a fastening hole is provided on the fixing ring. The filtering mechanism facilitates air filtration, thereby improving air quality.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] 1. When adjusting the opening and closing of this corrosion-resistant air valve, the operator can hold the actuator handle and grip. As the operator increases the grip strength, the grip will move closer to the actuator handle under the action of the grip strength. The movement of the grip will drive the positioning tooth plate to move upward. At this time, the actuator handle loses the positioning of the positioning tooth plate. The operator can push the actuator handle to control the opening and closing state of the valve plate. After the adjustment is completed, the operator releases the actuator handle. At this time, the positioning tooth plate moves downward under the action of the spring, so that the positioning tooth plate meshes with the tooth plate, achieving the purpose of locking the actuator handle. The operation is simple and can quickly lock the actuator handle of the air valve.

[0014] 2. This corrosion-resistant air valve has a filter mechanism installed at the air inlet. The filter screen can filter the passing air, intercepting some dust particles in the air, improving the quality of the air outlet and further enhancing the practicality of the air valve.

[0023] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-6 One embodiment of this utility model is: a corrosion-resistant air valve, including a valve body 1, a fixing frame 4 fixedly connected to the valve body 1, a valve stem 5 rotatably connected to the fixing frame 4 via a bearing, a valve plate 6 fixedly connected to the valve stem 5, an actuator 2 provided on the valve stem 5, and a corrosion-resistant coating sprayed on the surface and inside of the valve body 1. The corrosion-resistant coating can improve the corrosion resistance of the air valve, thereby further improving the service life of the air valve.

[0025] Actuator 2 includes an actuator handle 201 and a toothed plate 211. A fixed plate 202 is fixedly connected to the actuator handle 201, and a handle 203 is provided on the fixed plate 202. A connecting post 205 is fixedly connected to the bottom of the handle 203, and a positioning toothed plate 208 is fixedly connected to the lower end of the connecting post 205. A spring 206 is sleeved on the connecting post 205. A guide post 204 is fixedly connected to the handle 203. The positioning toothed plate 208 meshes with the toothed plate 211. A guide hole 209 is provided on the actuator handle 201, and the guide post 204 passes through the interior of the guide hole 209. When it is necessary to adjust the opening and closing of the air valve, the operator can hold the actuator handle 201 and the handle. 203. As the operator increases their grip strength, the handle 203 will move closer to the actuator 201 under the action of the grip strength. The movement of the handle 203 will drive the positioning tooth plate 208 to move upward. At this time, the actuator 201 loses the positioning of the positioning tooth plate 208. The operator can push the actuator 201 to control the opening and closing state of the valve plate 6. After the adjustment is completed, the operator releases the actuator 201. At this time, the positioning tooth plate 208 moves downward under the action of the spring 206, so that the positioning tooth plate 208 meshes with the tooth plate 211, thereby achieving the purpose of locking the actuator 201. The operation is simple and can quickly lock the actuator 201 of the air valve.

[0026] The actuator handle 201 is fixedly connected to the valve stem 5. The fixing plate 202 has a through hole, which allows the guide post 204 to pass through the fixing plate 202. The guide post 204 passes through the inside of the through hole. The positioning tooth plate 208 is fixedly connected to the limit rod 207. The guide post 204 can guide the handle 203.

[0027] The lower end of the spring 206 abuts against the positioning tooth plate 208, and the upper end of the spring 206 abuts against the bottom of the fixed plate 202. The limiting rod 207 is fixedly connected to the limiting block 210. The limiting block 210 can prevent the limiting rod 207 from disengaging from the fixed plate 202. The spring 206 can generate a pushing force on the positioning tooth plate 208, so that the positioning tooth plate 208 can mesh with the tooth plate 211.

[0028] The toothed plate 211 is fixedly connected to the fixed frame 4. A limit hole is opened on the fixed plate 202. The upper end of the limit rod 207 passes through the interior of the limit hole. The limit rod 207 can limit the positioning toothed plate 208 and prevent the positioning toothed plate 208 from shifting position.

[0029] A mark block 8 is fixedly connected to the actuator handle 201, a scale plate 9 is fixedly connected to the mounting bracket 4, and a connecting flange 7 is fixedly connected to the valve body 1. The mark block 8 and scale plate 9 make it easy for operators to control the opening and closing of the air valve, and the connecting flange 7 makes it easy for the air valve to be connected to the air duct.

[0030] Working principle: When the air valve needs to be opened or closed, the operator can hold the actuator handle 201 and the grip 203. As the operator increases the grip strength, the grip 203 will move closer to the actuator handle 201 under the action of the grip strength. The movement of the grip 203 will drive the positioning tooth plate 208 to move upward. At this time, the actuator handle 201 loses the positioning of the positioning tooth plate 208. The operator can push the actuator handle 201 to control the opening and closing state of the valve plate 6. When the adjustment is completed, the operator releases the actuator handle 201. At this time, the positioning tooth plate 208 moves downward under the action of the spring 206, so that the positioning tooth plate 208 meshes with the tooth plate 211, thereby achieving the purpose of locking the actuator handle 201. The operation is simple and can quickly lock the actuator handle 201 of the air valve.

The filter mechanism 3 includes a fixing ring 301, a filter ring 302 is fixedly connected to the fixing ring 301, a filter screen 303 is fixedly connected inside the filter ring 302, and the filter ring 302 is inserted into the air inlet of the valve body 1. A fastening hole 304 is provided on the fixing ring 301, and the fastening hole 304 can be aligned with the bolt hole on the connecting flange 7. The fastening hole 304 facilitates the installation and fixation of the fixing ring 301. The filter mechanism 3 facilitates the filtration of air, thereby improving air quality.

[0032] Working principle: By setting a filter mechanism 3 at the air inlet of the air valve, the filter screen 303 can filter the passing air, intercept some of the dust particles in the air, improve the air quality of the air outlet, and further improve the practicality of the air valve.
