Description

Technical Field

[0001] This utility model relates to the field of exhaust valve technology, specifically a manual exhaust valve. Background Technology

[0002] A manual exhaust valve is a device used to control the airflow discharge in a ventilation system. In cleaning equipment, the manual exhaust valve plays a key role. It mainly consists of a valve body, valve plate, valve shaft, handle, and sealing components. The valve body has an air inlet that is connected to the internal ventilation duct of the cleaning equipment, and an air outlet that leads to the outside.

[0003] Chinese patent CN2765016Y discloses a manual exhaust valve for purifying aluminum electrolysis flue gas. The valve includes a valve body with a limiting body and a valve plate inside. The valve plate is fixedly connected to a rotating shaft. The valve body has a shaft hole, and a support sleeve is provided around the shaft hole on the outer side of the valve body. The support sleeve has a sealing strip, a bushing, and an end cap. The rotating shaft is connected to a worm gear reducer through the shaft hole, support sleeve, sealing strip, bushing, and end cap. The worm gear reducer consists of a handwheel, a handle mounted on the handwheel, and a worm gear, and is fixed to the valve body by a bracket. This technical solution extends the service life of the manual exhaust valve, ensures the smooth operation of the entire flue gas purification system, and offers advantages such as flexible valve rotation, correct locking, and convenient operation.

[0004] Existing manual exhaust valves can only be fully open or fully closed. During the operation of cleaning equipment, different amounts of steam, odors and harmful gases will be generated. If the manual exhaust valve can only be fully open or fully closed, it is impossible to finely adjust the exhaust according to the actual amount of waste gas generated. At the same time, the adjustment between opening and closing the valve is relatively arbitrary, which leads to inaccurate control of the exhaust volume and wind speed.

[0005] To address the aforementioned issues, a manual exhaust valve is proposed. Utility Model Content

By adjusting the baffle plate angle, filtered fresh air can be precisely introduced while air containing particulate impurities and chemical waste gas is discharged, maintaining a stable production environment.

[0017] 3. The manual exhaust valve provided by this utility model allows for the liquefaction of steam in the external exhaust pipe of the cleaning equipment after the cleaning equipment stops operating, as the internal temperature decreases. The condensate then flows out of the equipment through this gap. The condensate may contain chemical cleaning agents used during the cleaning process. When this condensate containing chemicals flows to the outside of the equipment, it can corrode the outer shell, surrounding support structures, and connecting parts. The exhaust valve's liquid receiving tank and valve body guide port help guide the condensed liquid to the outside of the equipment, ensuring the equipment's aesthetic appearance.

[0026] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0027] Combine Figures 1 to 5 This utility model discloses a manual exhaust valve, comprising an exhaust valve body 1, an exhaust valve assembly 2 inside the exhaust valve body 1, the exhaust valve assembly 2 including an exhaust plate 201, the exhaust plate 201 being installed inside the exhaust valve body 1, a first connecting rod seat 202 welded to the bottom of the exhaust plate 201, and a connecting rod seat fastening screw 203 provided at the bottom of the first connecting rod seat 202, and a connecting rod threadedly connected to the outer wall of the connecting rod seat fastening screw 203. Extension seat 204, a wind deflector connecting rod 205 is welded to the side of extension seat 204, and a connecting rod extension seat 206 is welded to one end of the wind deflector connecting rod 205.

A V-shaped opening is provided at the top of the wind deflector 201. The first groove 210 has a V-shaped groove 210, and a baffle plate shaft 211 is welded to the side of the first groove 210. The baffle plate shaft 211 is fixedly connected to the exhaust valve body 1. The top of the second baffle plate 209 has a V-shaped groove 212, and a baffle plate shaft 213 is welded to one side of the second groove 212. The baffle plate shaft 213 is fixedly connected to the inner wall of the exhaust valve body 1. The other side of the second groove 212 is fixedly connected to a baffle plate shaft 214. Furthermore, the connection between the wind deflector shaft 214 and the exhaust valve body 1 is a fixed connection. The connecting rod seat fastening screw 203 passes through the first connecting rod seat 202 and the connecting rod extension seat 204 in sequence, and the connecting rod seat fastening screw 203 forms a threaded detachable structure through the first connecting rod seat 202 and the connecting rod extension seat 204. The wind deflector 201 and the wind deflector shaft 211 form a rotating structure, and the wind deflector 209 and the wind deflector shaft 213 form a rotating structure.

[0028] Adjusting the angle of the first wind deflector 201 causes it to rotate around the first wind deflector shaft 211. During rotation, the first wind deflector 201 drives the second wind deflector 209 to rotate around the second wind deflector shaft 213 via the first connecting rod seat 202, the first connecting rod seat fastening screw 203, the first connecting rod extension seat 204, the wind deflector connecting rod 205, the second connecting rod extension seat 206, the second connecting rod seat 207, and the second connecting rod seat fastening screw 208.

The wind deflector adopts a segmented design, with the wind deflector connecting rod 205 responsible for transmission. This helps reduce resistance, making operation easier and enabling high-precision control of ventilation volume. At the same time, when the ventilation system starts or stops, the sudden change in airflow will generate impact force. The connecting rod can evenly distribute these forces to each segment of the wind deflector, ensuring the stability of the entire wind deflector system.

[0029] Combine Figure 6 This utility model discloses a manual exhaust valve. An adjustment handle assembly 3 is provided on the side of the exhaust valve body 1.

When it is at the appropriate angle, tighten the wing nut 306. The adjustable angle of the baffle makes it easy to control the size of the baffle opening, which is beneficial to control the size and speed of the exhaust volume. Different cleaning stages or cleaning tasks will generate different amounts of waste gas. The adjustable angle of the baffle allows the ventilation volume to be precisely adjusted according to actual needs. For some places with strict ventilation requirements, precise control of ventilation volume can also ensure that the air cleanliness and temperature and humidity in the workshop meet the production requirements. By adjusting the angle of the baffle, filtered fresh air can be precisely introduced, while air containing particulate impurities and chemical waste gas can be discharged, maintaining a stable production environment.

[0032] After the cleaning equipment stops operating, the internal temperature will drop, and the steam in the external exhaust pipe of the cleaning equipment will be liquefied. The liquefied condensate will flow out of the equipment through this gap. The condensate may contain chemical cleaning agents used in the cleaning process. When this condensate containing chemicals flows to the outside of the equipment, it will cause corrosion to the outer shell of the equipment and the surrounding supporting structure and connecting parts. The exhaust valve liquid receiving tank 6 and the valve body guide port 9 are installed to guide the condensed liquid to the outside of the equipment and ensure the appearance of the equipment.
