Description

Technical Field

[0001] This application relates to the field of pipeline inspection, and more specifically, to an automatic valve shut-off alarm for waste heat boiler pipelines. Background Technology

[0002] The pipes inside the waste heat boiler are used to transport gas. The alarm can detect the temperature and pressure inside the pipe to determine whether there is a leak. When an abnormal pressure is detected in the pipe, the alarm can automatically sound and light an alarm to warn people and remind them to close the valve assembly. However, manually closing the valve can result in the valve not closing in time, while electric control requires the electric actuator to be installed on the pipe. The electric actuator is not convenient to install and remove, and it is not conducive to the maintenance of the electric actuator. Therefore, we propose an automatic valve closing alarm for waste heat boiler pipes. Utility Model Content

[0003] To overcome the shortcomings of existing devices, this application provides an automatic valve shut-off alarm for waste heat boiler pipelines, which can solve the problem of inconvenient operation of the aforementioned boiler pipeline alarms.

[0004] The technical solution adopted by the embodiments of this application to solve its technical problem is: an automatic valve shut-off alarm for waste heat boiler pipelines, including a boiler pipeline body and a clamping assembly.

[0005] A valve body is installed on the boiler pipe body, and a ring detection module is also installed on it. The clamping assembly is clamped on the boiler pipe body. An assembly cover is installed on the clamping assembly. Positioning parts and audible and visual alarms are respectively installed on the side walls at both ends of the assembly cover. The positioning parts are inserted into the valve body. A motor that drives the valve body is installed on the top of the assembly cover.

[0006] In one specific implementation, a transmission mechanism is installed on the valve body, and the motor drives the valve stem of the valve body through the transmission mechanism.

Detailed Implementation

[0020] The technical solution in this application embodiment is to solve the problem of inconvenient operation of the aforementioned boiler pipeline alarm. The overall idea is as follows:

[0021] Example:

[0022] Please see Figure 1-5 An automatic valve shut-off alarm for waste heat boiler pipelines includes a boiler pipeline body 10 and a clamping assembly 40.

[0023] A valve body 20 is installed on the boiler pipe body 10, and a ring detection module 30 is also installed on it. A clamping assembly 40 is clamped on the boiler pipe body 10, and an assembly cover 50 is installed on the clamping assembly 40. Positioning parts 60 and audible and visual alarms 70 are respectively installed on the two side walls of the assembly cover 50. The positioning parts 60 are inserted into the valve body 20. A motor 80 that drives the valve body 20 is installed on the top of the assembly cover 50. Specifically, a controller is also included. The controller is connected to the ring detection module 30, the audible and visual alarm 70 and the motor 80, so as to control the operation of the audible and visual alarm 70 and the motor 80 through the controller. The clamping assembly 40 can be removed from the boiler pipe body 10. The assembly cover 50 is installed on the clamping assembly 40. The motor 80 can be installed on the assembly cover 50 through a bolt structure. The positioning parts 60 are used to control the position between the motor 80 and the boiler pipe body 10, so as to facilitate the transmission connection between the motor 80 and the boiler pipe body 10.

[0024] See Figure 1 and 2 A transmission mechanism 210 is installed on the valve body 20. The motor 80 is driven by the valve stem of the valve body 20 through the transmission mechanism 210. In this configuration, the specific structure of the transmission mechanism 210 is the prior art. A first synchronous pulley is installed on the drive shaft of the transmission mechanism 210, and a second synchronous pulley is installed on the shaft of the motor 80. The same synchronous belt is wound around the first synchronous pulley and the second synchronous pulley so that the motor 80 drives the transmission mechanism 210 to drive the valve stem of the valve body 20 to rotate.

[0025] See Figure 2 The ring detection module 30 includes several temperature sensors 310 and several pressure sensors 320. The temperature sensors 310 and several pressure sensors 320 are all sealed through the boiler pipe body 10 and are arranged alternately. In a specific setting, the temperature sensors 310 and several pressure sensors 320 can simultaneously detect inside the boiler pipe body 10, which can improve the accuracy of the detection of the boiler pipe body 10. The temperature sensors 310 and several pressure sensors 320 are connected to the controller.

[0026] See Figure 2 and 3 The clamping assembly 40 includes two arc-shaped clamping plates 410, which are sleeved on the boiler pipe body 10. Two screws 420 slide through the two arc-shaped clamping plates 410, and each screw 420 is connected to a nut 430. Specifically, the assembly cover 50 is installed on one of the arc-shaped clamping plates 410. The two screws 420 pass through both ends of the arc-shaped clamping plate 410 and are locked to the boiler pipe body 10 by the two nuts 430. Furthermore, several buffer rods 440 slide through the arc-shaped clamping plate 410, and the two ends of the buffer rods 440 are respectively... A buffer block 450 and a connecting block 460 are installed. The buffer block 450 is placed on the boiler pipe body 10. A spring 470 sleeved on the buffer rod 440 is connected between the connecting block 460 and the boiler pipe body 10. When the arc-shaped clamp 410 is installed on the boiler pipe body 10, several buffer blocks 450 are attached to the outer wall of the boiler pipe body 10. Thus, during the locking process by the screw 420 and nut 430, the buffer rod 440 will pull the spring 470 through the connecting block 460 to prevent excessive locking force from damaging the boiler pipe body 10.

[0027] See Figure 4 and 5The positioning component 60 includes a horizontal plate 610 fixedly installed on one side wall of the assembly cover 50. A groove 620 is provided on the horizontal plate 610. A threaded rod 630 is rotatably connected between the two side walls of the groove 620. A slider 640 is threadedly sleeved on the threaded rod 630. A positioning plate 650 is fixedly connected to the slider 640. A positioning block 660 is slidably connected to one end of the positioning plate 650. The positioning block 660 is inserted into one side wall of the valve body 20. It should be noted that a slot is provided on the side wall of the valve body 20. One end of the positioning block 660 is inserted into the slot to achieve the positioning purpose between the motor 80 and the transmission mechanism 210. By rotating the threaded rod 630, the position between the motor 80 and the transmission mechanism 210 can be adjusted to facilitate straightening the synchronous belt. Furthermore, a turntable 670 is fixedly sleeved on the threaded rod 630. By setting the turntable 670 on the threaded rod 630, the purpose of facilitating the rotation of the threaded rod 630 can be achieved.

[0028] See Figure 5 A limiting rod 680 is fixedly installed on one side wall of the positioning block 660. The limiting rod 680 slides through the positioning plate 650. Specifically, the positioning plate 650 has a through hole that matches the limiting rod 680, so that the limiting rod 680 can rise and fall in the through hole, thereby facilitating the adjustment of the position of the positioning block 660 and allowing the positioning block 660 to be inserted into the slot.

[0029] When this application is used:

[0030] When the boiler pipe body 10 is working, several temperature sensors 310 and several pressure sensors 320 simultaneously detect the internal temperature and pressure of the boiler pipe body 10. When an abnormality occurs, the data is fed back to the controller, which then controls the motor 80 to operate. The motor 80 drives the valve stem of the valve body 20 to rotate through the transmission mechanism 210, thereby closing the boiler pipe body 10. At the same time, the controller controls the audible and visual alarm 70 to operate, so as to issue an alarm and remind the staff to handle the situation.

[0031] It should be noted that the specific models and specifications of the valve body 20, transmission mechanism 210, temperature sensor 310, pressure sensor 320, audible and visual alarm 70, and motor 80 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0032] The power supply and operating principles of the valve body 20, transmission mechanism 210, temperature sensor 310, pressure sensor 320, audible and visual alarm 70, and motor 80 are clear to those skilled in the art and will not be described in detail here.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
