Description

Technical Field

[0001] The utility model mainly relates to the technical field of closed regulating valves, in particular to an electric low-temperature resistant closed regulating valve. Background Art

[0002] With the continuous development of science and technology, the continuous progress of hollow glass, sealing and insulation technology, houses have become highly airtight containers. Fresh air from the outside cannot enter the room, and the smoke, moisture and odor in the room are all blocked in the house, which is no different from a "gas tank". Such an environment is harmful to people's health and life. The use of a fresh air system can solve this problem, and the air volume control valve is an important component in the fresh air system. The air volume control valve can not only be used for the mixed adjustment of fresh air and return air, but also is an indispensable central air conditioning terminal accessory in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings. Using an air volume control valve, you can enjoy the fresh air of nature without opening the window. Through effective ventilation, keep the indoor air fresh, improve comfort, and ensure human health.

[0003] For example, Chinese patent publication number CN218454967U discloses a multifunctional closed regulating valve, including a rectangular air duct, a rectangular air valve and a flange mounting hole. The rectangular air valve is detachably assembled on one side of the rectangular air duct, the inner wall of the rectangular air valve is detachably assembled with two air valve blades, and the surface of the rectangular air valve is detachably assembled with a valve control shaft.

[0004] When the above application needs to use the equipment, lubricating liquid is added to the oil storage tank from the feeding port, the latch is slid, and the third spring is deformed by force to generate elastic force, and the tank cover is inserted into the feeding port on the surface of the oil storage tank. The latch is released, and the third spring releases the elastic force, driving the latch to be inserted into the card hole on the surface of the plug block. The oil storage tank flows the lubricating liquid into the oil guide pipe through the conduit for smearing. The detachable assembly auxiliary module facilitates lubrication of the equipment, which can effectively reduce the rust and corrosion phenomenon at the control part of the equipment, and reduce the situation where the equipment cannot be rotated and adjusted to affect the use, thereby improving the overall practicality of the equipment. However, the closed regulating valve in the prior art does not have the performance of resisting low temperature and anti-icing. Low temperature may cause the valve body, valve core and sealing material to harden, resulting in a decrease in sealing performance, thereby increasing the risk of leakage. Utility Model Content

Example

[0030] See attached Figures 1 to 6 An electric low-temperature resistant closed regulating valve comprises a mounting frame 1, a plurality of valve leaf assemblies 2 are arranged at equal distances in the mounting frame 1, a control assembly 3 is arranged at the upper end of the mounting frame 1, and the control assembly 3 is used to control the opening and closing of the valve leaf assembly 2, a water tank 4 is arranged on the outer side of the mounting frame 1, a heating wire 41 and a water pump 42 are arranged in the water tank 4, a water inlet 5 is arranged on the water tank 4, and the output end of the water pump 42 is connected to the main water inlet pipe 8, and the main water inlet pipe 8 is used to supply hot water to the valve leaf assembly 2 and heat the valve leaf assembly 2.

[0031] The valve leaf assembly 2 includes two symmetrically arranged valve leaves 21, and an installation cavity 22 is formed between the two valve leaves 21. A rotating tube 23 is arranged at the center of the installation cavity 22. The rotating tube 23 is rotatably installed on the mounting frame 1. A heat conducting block 24 is arranged on the rotating tube 23, and the heat conducting block 24 is connected to the valve leaf 21 through a plurality of heat conducting sheets 25.

[0032] The main water inlet pipe 8 is provided with a plurality of connecting branches 81, and a connector 82 is installed on the connecting branch pipe 81, and each connector 82 is connected to a rotating pipe 23. The arrangement of the connecting head 82 facilitates the connection with the rotating pipe 23, thereby facilitating disassembly, assembly and maintenance.

[0033] The other end of the rotating tube 23 is connected to the main water outlet pipe 6 , the structure of the main water outlet pipe 6 is the same as the main water inlet pipe 8 , both ends of the main water outlet pipe 6 are connected to the circulation pipe 7 , and the other end of the circulation pipe 7 is arranged in the water tank 4 .

[0034] The control assembly 3 includes a mounting slot 31 disposed at the upper end of the mounting frame 1. A motor 32 is fixedly mounted on the mounting frame 1. The motor 32 is connected to a reciprocating mechanism 33. The reciprocating mechanism 33 adopts a crank slider mechanism. The reciprocating mechanism 33 is used to convert the rotational motion of the motor 32 into a linear motion. The reciprocating mechanism 33 is connected to a connecting bar 34. A plurality of connecting rods 35 are installed on the connecting bar 34. The other end of each connecting rod 35 is connected to the rotating tube 23. The motor 32 is a power source and provides rotational motion. The reciprocating mechanism 33 adopts a crank slider mechanism. The crank slider mechanism is a common mechanical transmission device that can convert rotational motion into reciprocating linear motion. In this control assembly, the rotational motion of the motor 32 is converted into linear reciprocating motion through the reciprocating mechanism 33. The connecting bar 34 connects the reciprocating mechanism 33 and the connecting rod 35. It plays a role in transmitting motion and force, ensuring that the motion of the reciprocating mechanism 33 can be effectively transmitted to the connecting rod 35. The connecting rod 35 converts the linear motion of the reciprocating mechanism 33 into the rotational motion of the rotating tube 23. The design of the connecting rod 35 allows the reciprocating motion to be converted into a rotary motion through a series of mechanical amplifications.

[0035] The rotating tube 23 is connected to the connecting rod 35 , and finally receives the rotating motion from the connecting rod 35 , so that the rotating tube 23 can rotate, thereby controlling the opening and closing of the valve leaf assembly 2 .

[0036] Working principle: the water tank 4, the rotating tube 23, the heat conducting block 24 and the heat conducting sheet 25 are all made of heat conducting materials.

[0037] When using the closed regulating valve in winter or in a low temperature environment, open the water inlet 5, add water to the water tank 4, connect power to the heating wire 41, and the heating wire 41 heats the water in the water tank 4. The water tank 4 transfers the temperature to the inside of the mounting frame 1, and at the same time starts the water pump 42. The hot water is transported to the rotating tube 23 of the valve leaf assembly 2 through the main water inlet pipe 8 and the connecting branch pipe 81. The heat of the rotating tube 23 is transferred to the valve leaf 21 through the heat conductive block 24 and the heat conductive sheet 25 to heat the valve leaf assembly 2. This can effectively prevent the valve leaf assembly 2 from becoming stiff due to cooling under low temperature conditions. Then the hot water enters the water tank 4 through the main water outlet pipe 6 and the circulation pipe 7 and circulates for heating. The hot water can continue to contact the heat source during the circulation process, reducing heat loss. Compared with hot water that is discharged immediately after a one-time use, the circulating heating system can maintain the water temperature and reduce heating time and energy consumption.

[0038] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
