DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0025] As Figures 1-5 shown, a pressure sensing safety valve includes a safety valve body 1 and a sealing wire 8. The pressure adjustment of the safety valve body 1 and the installation of the sealing wire 8 are both prior arts, so no further elaboration will be made here. An installation plate 2 is provided on the side wall of the safety valve body 1, and a recording mechanism for recording pressure adjustment information is provided on the side wall of the installation plate 2. The recording mechanism includes an installation housing 7 provided on the side wall of the installation plate 2. A touch screen 3 (model can be Mitsubishi touch screen GT1030-HBD) is provided on the side wall of the installation housing 7. A storage module 4 (model can be AT24C256, W25Q64), a microcontroller 5 (model can be STM32F103C8T6, PIC16F877A, ESP32) and a wireless module 6 (model can be ESP8266 Wi-Fi module, ESP32Wi-Fi and Bluetooth module) are provided inside the installation housing 7.

[0026] A monitoring mechanism for monitoring the sealing wire 8 is provided on the installation housing 7. The monitoring mechanism includes a fixed housing 15 provided on the installation housing 7. A sliding block 14 is elastically connected to the inner wall of the fixed housing 15 through a spring 20. A touch switch 16 is provided on the installation housing 7, and a limiting rod 12 is provided on the side wall of the sliding block 14.

[0027] In the present utility model, an alarm 13 is provided at the upper end of the installation housing 7, and a buzzer 19 is provided on the installation housing 7, which can perform sound and light alarms to remind people that the sealing wire 8 is pulled.

[0028] In the present utility model, two connecting blocks 11 are fixedly connected to both side walls of the installation housing 7, and bolts are provided on the side walls of the connecting blocks 11, so that the installation housing 7 can be disassembled, which is convenient for disassembling the installation housing 7 for maintenance.

[0029] In the present utility model, a limiting groove 10 is opened at the upper end of the installation plate 2, and a limiting plate fixedly connected to the installation housing 7 is provided in the limiting groove 10, so that when the installation housing 7 is installed, there is no need to manually position the installation housing 7 on the side wall of the installation plate 2.

[0030] In the present utility model, two slide rails 21 are fixedly connected to the side wall of the installation housing 7, and a sunshade 9 is slidably connected in the two slide rails 21 together, which can provide a sunshade function for the touch screen 3 to avoid the touch screen 3 being exposed to the sun for a long time.

[0031] In the present utility model, a placement frame 17 is fixedly connected to the side wall of the installation housing 7. A baffle 18 penetrates through the upper end of the placement frame 17, and a paper record form can be placed in the placement frame 17, so that the inspection personnel can check it at any time.

[0032] In this utility model, the placement frame 17 is made of acrylic material. The placement frame 17 made of acrylic material is transparent, and the content of the record form can be directly observed. A through groove is provided on the side wall of the sunshade 9 to facilitate the movement of the sunshade 9.

[0033] It should be noted that this utility model is a pressure-sensing safety valve. When the user adjusts the pressure of the safety valve body 1, relevant information such as the pressure adjustment time, the pressure adjustment value, the sealing lead time, and the personnel can be input through the touch screen 3. When the safety valve body 1 is maintained, the maintenance personnel can directly display the relevant information of the pressure adjustment through the touch screen 3 without searching for a paper record form, thus facilitating the maintenance of the safety valve.

[0034] During daily use, the limiting rod 12 is always attached to the sealing lead rope 8. When the sealing lead rope 8 is pulled, the limiting rod 12 will be dragged. The limiting rod 12 pulls the sliding block 14 to move. When the sliding block 14 touches the touch switch 16, the storage module 4 records this abnormality, and the wireless module 6 can send the abnormality to relevant terminals (mobile phones, workshop control systems) to remind people of the safety valve that an abnormality has occurred.
