Embodiment Construction
[0016] refer to figure 1 , The pressure-sensing flow switch includes a switch body 1, a proximity switch assembly 2, a sensing piston 3, a damper 4, a spring 5 and a right end cover 6.
[0017] The switch body 1 is a block, part of which has a working chamber 11 in the longitudinal direction. The working chamber 11 is a round hole for accommodating the sensing piston 3. The surface of the round hole is finely processed to ensure that the sensing piston 3 can move freely. Move to form a sliding fit, and can ensure good sealing between the mating surfaces of the two; the working chamber 11 and other related parts of the configuration together form a sealed working chamber;
[0018] The left chamber 12 in the switch body 1 is a part of the left side of the working chamber 11, and is a sealed space jointly formed by the working chamber 11, the bottom surface of the left end cover 20 of the proximity switch assembly 2, the left end surface of the sensing piston 3 and the correspond...
