Description

Technical Field

[0001] The utility model belongs to the technical field of pressure monitoring, and in particular relates to a pressure monitoring alarm linkage cutting device. Background Art

[0002] Existing buildings and shopping malls generally use pipeline gas as kitchen fuel. Sometimes during use, the gas transmission device sometimes fails due to aging, causing excessive gas pressure in the transmission pipeline, which in turn makes the pipeline prone to the risk of bursting. Therefore, a pressure monitoring alarm linkage cut-off device is needed to solve the above problem. Utility Model Content

[0003] The purpose of the utility model is to provide a pressure monitoring alarm linkage cut-off device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure monitoring alarm linkage cut-off device, comprising a valve body, a bevel gear rotatably connected inside the valve body, a motor is arranged at the rotation point between the bevel gear and the outside of the valve body, a bevel gear ring is meshed on one side of the bevel gear, an annular tooth is fixedly connected on one side of the bevel gear ring, one side of the annular tooth is annularly rotatably connected in the valve body through a T-shaped ring slider, two fixed blocks are fixedly connected inside the valve body, one side of the two fixed blocks are rotatably connected with a threaded rod, the upper parts of the two threaded rods are commonly threadedly connected with a first valve block, the first valve block is slidably connected in the valve body, one end of the two threaded rods are rotatably connected with a connecting block, the far sides of the two connecting blocks are fixedly connected in the valve body, one side of the two fixed blocks are commonly fixedly connected with a second valve block, the two threaded rods are fixedly connected with a gear at the rotation point between one end of the fixed block, the two gears are meshed with the inside of the annular tooth, a control device and a pressure monitoring device are respectively arranged on the valve body, and an audible and visual alarm is arranged on the control device.

[0005] When the pressure monitoring device detects that the pressure in the valve body is too high, it will start the motor through the control device. Under the power output of the motor, the meshing transmission of the bevel gear and the ring gear will drive the ring gear to rotate. The ring gear drives the threaded rod to rotate through the meshing transmission of the gears. The two threaded rods drive the first valve block to move to one side through synchronous rotation and fit with the second valve block, so that the second valve block can just block the air outlet on one side of the first valve block, so that the gas in the valve body can be blocked in time. During this period, the sound and light alarm will also send out sound and light alarms synchronously, so that the gas will not flow into the delivery pipeline through the valve body and cause safety hazards to it, thereby helping to ensure a certain degree of safety.

[0006] As a preferred implementation, the motor is fixedly arranged outside the valve body.

[0007] As a preferred implementation, the second valve block is located in the valve body.

[0008] As a preferred implementation manner, the first valve block and the second valve block correspond to each other.

[0009] As a preferred implementation, the first valve block is funnel-shaped.

[0010] By setting the first valve block to be funnel-shaped, when the air pressure in the first valve block is relatively high, due to the spatial characteristics from large to small in the first valve block, the airflow will squeeze one side of the first valve block and make the first valve block tend to move toward the second valve block, so that the first valve block can rotate and move more smoothly and quickly.

[0011] As a preferred implementation, the pressure monitoring device is located on one side of the first valve block.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the utility model, when the pressure monitoring device detects that the pressure in the valve body is too large, the motor will be started through the control device. Under the power output of the motor, the meshing transmission of the bevel gear and the ring gear will drive the ring gear to rotate. The ring gear drives the threaded rod to rotate through the meshing transmission of the gears. The two threaded rods drive the first valve block to move to one side through synchronous rotation and fit with the second valve block, so that the second valve block can just block the air outlet on one side of the first valve block, thereby allowing the gas in the valve body to be blocked in time. During this period, the sound and light alarm will also synchronously send out sound and light alarms, so that the gas will not flow into the delivery pipeline through the valve body to cause safety hazards, thereby helping to ensure a certain degree of safety.

[0014] The utility model sets the first valve block to be funnel-shaped, so that when the air pressure in the first valve block is relatively high, due to the spatial characteristics from large to small in the first valve block, the airflow will squeeze one side of the first valve block and make the first valve block tend to move toward the second valve block, so that the first valve block can be rotated and displaced more smoothly and quickly.
