Description

Technical Field

[0001] The utility model relates to the technical field of pressure controllers, in particular to a pressure controller with a high protection level. Background Art

[0002] A pressure controller is a device used to monitor and regulate the pressure of a fluid or gas in a system. It usually includes a sensor part and an electronic or mechanical component that performs the control. The main function of a pressure controller is to ensure that the pressure in the system is always maintained within a preset safety range or operating range. When the system pressure exceeds or falls below the set threshold, the pressure controller will adjust the flow of fluid or gas by controlling valves, pumps or other actuators to maintain the desired pressure level.

[0003] After searching, CN112256085B is specifically named as a pressure controller, including a pressure sensing part, a transmission part, and a micro switch assembly. The pressure sensing part transmits displacement through the transmission part to control the action of the micro switch assembly; the pressure controller also includes a locking part, which can cooperate with the transmission part to lock when in the locking position, and also includes a reset part, which can be switched from an initial position to a reset position under the action of an external force, and can unlock the locking part in the reset position to make it in the unlocking position;

[0004] When a traditional pressure controller is installed in a high-pressure pipeline, for example, when a liquid or gas is suddenly closed or blocked in a pipeline, the internal pressure of the pipeline will suddenly increase, and the instantaneous pressure will be too high, which can easily cause damage to the pressure controller. The instantaneous pressure increase exceeds the design tolerance of the pressure controller and may cause damage or rupture of the pressure controller parts. The damaged pressure controller needs to be repaired or replaced, which not only increases maintenance costs, but may also increase production downtime. Utility Model Content

The instantaneous pressure increase exceeds the design tolerance of the pressure controller and may cause damage or rupture of the pressure controller components. The damaged pressure controller needs to be repaired or replaced, which not only increases maintenance costs but may also lead to increased production downtime.

[0008] Preferably, under normal conditions, the elasticity of the spring enables the surface of the sealing plate to be sealingly attached to the surface of the positioning plate.

[0009] Preferably, the interior of the sealing groove is connected to the exterior of the input pipe through the air inlet pipe, the blocking groove and the air passage groove, and the outer surface of the blocking block is movably connected to the interior of the blocking groove.
