Magnetic reed pipe conductive wind-pressure switch

Abstract

The invention discloses a magnetic reed pipe conductive wind-pressure switch which includes a left casing and a right casing. An elastic membrane sheet is sandwiched between the left casing and the right casing. The elastic membrane sheet enables an internal space of the left casing and the right casing to be separated and divides the internal space of the left casing and the right casing into a positive-pressure chamber and a negative-pressure chamber. A pair of fixed clamping pieces is clamped on the elastic membrane sheet. A spring column is arranged on each fixed clamping piece, wherein a magnetic ring is sleeved at the periphery of the spring column of the fixed clamping sheet arranged in the negative-pressure chamber and the magnetic ring is fixed on the fixed clamping sheet of the negative-pressure chamber; an adjustment screw rod is arranged at each of the middle positions of the left casing and the right casing and springs are sleeved between the adjustment screw rods and the spring columns; and a position of the outer surface of the right casing, close to the central position, is provided with a reed-pipe switch which is in the same horizontal direction with the magnetic ring. Compared with the prior art, the magnetic conductive wind-pressure switch has the advantages of being simple in structure, low in cost, precise in measurement, fast in power-on / power-off and great in effect and the like.

Description

technical field [0001] The invention relates to a wind pressure switch, in particular to a conductive wind pressure switch of a magnetic reed switch. Background technique [0002] The wind pressure switch is a detection device, which is generally used on machines that require wind pressure, such as wall-hung boiler water heaters, gas boilers, and wall-hung boiler heating equipment that use gas-fired electrical products. It is required that the negative pressure cavity of the wind pressure switch communicates with the air supply channel in the fan worm gear casing, and the diaphragm of the wind pressure switch is sent out by strong wind to drive the conductive electrode to connect or use the magnetic suction conductive electrode to connect the power to start other electrical appliances. Parts to complete the product to work properly. The important function of the air pressure switch is to use its on-off capability to control the on-off of the entire set of electrical product...

AI Technical Summary

Problems solved by technology

Since the air pressure switch is usually used in an environment where the temperature alternates between hot and cold, the inside of the air pressure switch is a closed space. If air is added to the product, water will be generated inside the product due to the temperature difference. If the inside of the air pressure switch Water will affect the use effect of the product, the spring in the inner cavity will rust, and the diaphragm is easy to age
