Mechanical fully automatic temperature control switch valve

Abstract

A mechanical fully automatic temperature control valve includes a temperature control valve for mounting on an equipment box. The temperature control valve has a valve body with an axially formed shaft hole and an inlet channel and an outlet channel on its side, which communicate with the shaft hole. The valve body allows compressed gas to pass through the inlet channel, shaft hole, and outlet channel. The outlet channel communicates with the inside of the equipment box. A valve control device and a temperature control device are installed in the shaft hole. The valve control device uses a spring to push a valve to block the communication between the inlet channel and the outlet channel. The temperature control device has a temperature sensing element. When the temperature senses an increase, the temperature sensing element can convert thermal energy into kinetic energy to push a valve stem. The valve stem can push the valve to temporarily connect the inlet channel and the outlet channel. The valve body and the equipment box are assembled and fixed, with the temperature sensing element extending out of the valve body and located inside the equipment box.

Claims

1. A mechanical fully automatic temperature-controlled switching valve, comprising a temperature-controlled switching valve for mounting on an equipment box, wherein: The temperature-controlled switch valve has a valve body with an axially formed shaft hole and an inlet channel and an outlet channel on its side, both communicating with the shaft hole. Compressed gas is supplied through the valve body via the inlet channel, shaft hole, and outlet channel. The outlet channel communicates with the interior of the equipment housing. A valve control device and a temperature control device are installed in the shaft hole. The valve control device uses a spring to push a valve, temporarily connecting the inlet and outlet channels. The temperature control device has a temperature-sensing element. When the temperature rises, the temperature-sensing element converts heat energy into kinetic energy to push a valve stem. The valve stem pushes the valve, temporarily connecting the inlet and outlet channels. The valve body is fixedly assembled with the equipment housing, with the temperature-sensing element extending through the valve body and located inside the equipment housing. When the temperature drops, the temperature-sensing element causes the valve stem to return to its original position, resetting the valve and blocking the connection between the inlet and outlet channels. The equipment housing has a heat dissipation check valve for unidirectional air discharge from the equipment housing.

2. The mechanical fully automatic temperature control switch valve as described in claim 1, further comprising a vortex-type cold air gun, wherein, The vortex-type cold air gun is equipped with a vortex generating chamber. The vortex generating chamber has an axially arranged cold air outlet and a hot air outlet. The vortex generating chamber has a laterally arranged compressed gas inlet, which is connected to the outlet channel. The vortex increases the pressure and density on its outer side and decreases on its inner side through centrifugal force, causing the vortex to release energy from the inside to the outside to form cold air and hot air. The cold air is blown into the equipment box through the cold air outlet to help cool down, and the hot air is discharged through the hot air outlet. A regulating valve is provided at the hot air outlet to control the discharge volume of the hot air.

3. The mechanical fully automatic temperature control switch valve as described in claim 2, wherein, The temperature control switch valve is separate from the vortex-type cold air gun.

4. The mechanical fully automatic temperature control switch valve as described in claim 2, wherein, The temperature control switch valve is integrated with the vortex-type cold air gun.

5. The mechanical fully automatic temperature control switch valve as described in any one of claims 1 to 4, wherein, The equipment box is equipped with an inlet check valve, through which the compressed air system enters the equipment box.

6. The mechanical fully automatic temperature control switch valve as described in any one of claims 1 to 4, wherein, When the temperature sensing element detects a temperature of 30±1.5℃, it causes the valve stem to gradually push the valve, allowing compressed gas to pass through the shaft hole; when the temperature sensing element detects a temperature of 25±1.5℃, it causes the valve stem to gradually return to its original position, causing the valve to reset and block the compressed gas from passing through the shaft hole.

7. The mechanical fully automatic temperature control switch valve as described in any one of claims 1 to 4, wherein, The temperature sensing element controls the opening and closing of the valve when the temperature is sensed to be between 55°C and 70°C, and the compressed gas is nitrogen.

8. The mechanical fully automatic temperature control switch valve as described in any one of claims 1 to 4, wherein, The valve body has an external thread on the bottom outer side, which is screwed and clamped onto the equipment box with a threaded ring, thereby installing and fixing the temperature control switch valve onto the equipment box.

9. The mechanical fully automatic temperature control switch valve as described in any one of claims 1 to 4, wherein, The valve control unit has a valve control shaft in its central screw assembly, and the spring is provided between the valve control shaft and the valve.

10. The mechanical fully automatic temperature control valve as described in any one of claims 1 to 4, wherein, The temperature control switch valve is equipped with several gaskets to increase airtightness.
