Abstract

The invention provides a wind pressure switch which comprises a shell, a driving device, a contact action device and a pressure adjusting device, the pressure adjusting device comprises a biasing member, a guide structure, and an operation knob; the one end of the biasing member is arranged on the other side of a triggering structure corresponding to a push rod, the acting force direction is parallel to the acting force direction of the push rod, and a sliding part is arranged at the other end of the push rod; the guide structure limits the sliding part to slide along the acting force direction of the biasing member; and the operation knob is rotationally arranged on the shell, a driving structure connected with the sliding part facing the inside of the shell, and the operation knob drivesthe driving structure to drive the sliding part to move in the rotation process. In the present invention, the pressure value corresponding to the size of the wind pressure switch can be adjusted bydirectly rotating the operation knob manually, without the need of any external tools, the adjustment is convenient and manpower is saved, the accuracy and stability of the pressure value in the shellis guaranteed, the wind magnitude of the device with the wind pressure can be accurately monitored, the structure is compact and reliable, and the use is safe and reliable.

Description

technical field [0001] The invention relates to the field of gas appliances, in particular to a wind pressure switch. Background technique [0002] The wind pressure switch is a detection element, generally used in machinery that requires wind pressure, such as pneumatic presses, pneumatic shears, gas water heaters, gas boilers, gas furnaces, wall-hung furnaces and other electrical products that use gas. Use the static pressure of the gas to push the micro switch to realize the on-off of the current, and control the work of the electrical product through its on-off capability. [0003] The current common wind pressure switch is described in Chinese patent document CN204204742U, which discloses a wind pressure switch, including a left casing, a right casing and a micro switch, and a diaphragm is sandwiched between the left casing and the right casing , so that the cavity between the left shell and the right shell forms the left air chamber and the right air chamber, the micr...
