[0021] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0022] like Figure 1-Figure 6As shown, this embodiment provides an explosion-proof gas-controlled deluge valve temperature control device, including an explosion-proof box 1, a deluge valve body 2, a gas control device 3 and a temperature control device. The deluge valve body 2 is placed in the explosion-proof box 1, the gas control device 3 is installed on the deluge valve body 2, the temperature control device is installed on the inner wall of the explosion-proof box 1, and the temperature control device is provided with a temperature sensor 5 installed on the deluge valve body 2. Specifically, an alarm pipeline 15 is also installed on the deluge valve body 2. The deluge valve body 2 is protected by the explosion-proof box 1, and the air pressure in the deluge valve body 2 is controlled by the gas control device 3. Then the temperature sensor 5 monitors the water temperature in the pipeline of the deluge valve body 2. When the water temperature is lower than 4°C, the temperature control device starts heating to maintain the pipeline temperature in the range of 4-20°C to prevent the pipeline from being damaged by low temperature due to low outdoor temperature in winter.

[0023] Furthermore, the air control device 3 includes an electromagnetic air control valve 6 and a manual air control valve 7, and both the electromagnetic air control valve 6 and the manual air control valve 7 are connected to the shower valve body 2. Through the electromagnetic air control valve 6 and the manual air control valve 7, electric control or received control is achieved to prevent the air pressure in the shower valve body 2 from being unable to be controlled after one of them is damaged.

[0024] Furthermore, the temperature control device includes four explosion-proof electric heating cables 4, which are respectively placed on four inner walls of the explosion-proof box 1, and the bending disks of the explosion-proof electric heating cables 4 are arranged on the inner wall surface of the explosion-proof box 1. The interior of the explosion-proof box 1 is heated simultaneously by the four explosion-proof electric heating cables 4 to ensure that the pipe temperature of the deluge valve body 2 is maintained in the range of 4-20.

[0025] Furthermore, the side wall of the explosion-proof box 1 includes an explosion-proof shell 8 and a heat-insulating flame-retardant partition 9, which is fitted on the explosion-proof shell 8, and the temperature control device is placed on the heat-insulating flame-retardant partition 9. The explosion-proof shell 8 is provided to increase the explosion-proof property, and the heat-insulating flame-retardant partition 9 is provided to insulate and flame-retard the interior of the explosion-proof box 1.

[0026] Furthermore, a buffer gap is provided between the thermal insulation and flame retardant partition 9 and the adjacent thermal insulation and flame retardant partition 9, and a plurality of buffer columns 10 are provided on the explosion-proof shell 8 extending toward the buffer gap. The buffer columns 10 between adjacent explosion-proof shells 8 are staggered, and the buffer columns 10 are connected to the thermal insulation and flame retardant partition 9 on the adjacent explosion-proof shells 8. Specifically, the buffer columns 10 are made of elastic rubber. When the explosion-proof box 1 receives the impact of the explosion, the buffer gap and the plurality of buffer columns 10 are used for movement and compression buffering, thereby further reducing the damage of the impact force to the explosion-proof box 1, that is, when the shock wave hits one of the explosion-proof shells 8, the explosion-proof shell 8 moves toward the buffer gap and compresses the plurality of buffer columns 10 to play a buffering role.

A plurality of elastic members 11 are evenly distributed in the receiving groove, and a protective plate 12 is installed on the plurality of elastic members 11, and there is a movable gap between adjacent protective plates 12. Specifically, the explosion-proof electric heating belt 4 is placed between adjacent elastic members 11. By providing the elastic members 11 and the protective plates 12, when the pipeline of the shower valve body 2 inside the explosion-proof box 1 bursts, its impact force will act on the protective plate 12 and then be buffered by the elastic member 11, thereby protecting its temperature control device and preventing the impact force from causing serious damage to the temperature control device, resulting in its being scrapped and unable to be reused. In addition, there is a movable gap between adjacent protective plates 12, which can firstly allow the protective plate 12 to have a buffering movable space, and secondly, can ensure that the heat energy heated by the explosion-proof electric heating belt 4 can flow out through the movable gap without affecting the heating of the explosion-proof box 1 by the explosion-proof electric heating belt 4.

[0028] Furthermore, an impact force sensor 13 is embedded in the heat-insulating flame-retardant partition 9, and a control panel 14 is installed outside the explosion-proof housing 8. The impact force sensor 13 is connected to the control panel 14 by wires, and a wireless sensor wirelessly connected to an external communication device is installed in the control panel 14. The external communication device is a conventional computer monitoring device. When the explosion-proof box 1 receives an explosion shock, it can be sensed by the impact force sensor 13 and transmitted to the control panel 14, and then sent to the external communication device through the control panel 14 at the first time, so as to remind the staff at the first time which explosion-proof box 1 has a problem.

[0029] Furthermore, the explosion-proof housing 8 includes a first explosion-proof steel plate, a second explosion-proof steel plate and a filling layer, wherein the first explosion-proof steel plate and the second explosion-proof steel plate are arranged in parallel, and the filling layer is filled and placed between the first explosion-proof steel plate and the second explosion-proof steel plate; the filling layer includes a fiber cement composite steel plate and a rock wool layer, and the fiber cement composite steel plate and the rock wool layer are arranged in a laminated manner.
