Abstract
The utility model relates to a pressure control switch, which comprises a casing 1. The bottom of the casing is provided with a medium inlet 14, and the upper part is provided with a movable sealing cover 4; a partition film 2 which is provided with a sealing ring 6 is arranged below the sealing cover; the center of the sealing cover is provided with a piston 3 above the partition film 2; the piston is provided with a spring 7 and a dynamic supporting column 8; a lever type moving contact 10 is arranged above the dynamic supporting column and the spring, and a return spring 9 is arranged in the opposite direction thereof; one end of the moving contact 10 is a switch which is provided with a normally open contact and a normally closed contact. The utility model, which is particularly suitable for the water outlet end of a quick-heating water heater, can achieve the purposes that when water exists, electricity exists, and when water is cut off, electricity is cut off.
Description
The utility model relates to a kind of electric control gear of fluid medium pressure, a kind of pressure control switch.
Existing pressure control switch has varied, generally is made up of pressure sensor and control instrument, and structure is quite complicated, and instrument and transducer branch be arranged, and occupation space is bigger.
The purpose of this utility model provides compact, the cheap and outstanding effect pressure control switch of a kind of structure.
The utility model is realized by following scheme:
A kind of pressure control switch, it comprises shell, outer casing bottom has the medium inlet, the activity capping is arranged at top, is the barrier film that has sealing ring under the capping, on the barrier film, there are a piston in capping central authorities, spring and dynamic pillar are arranged on the piston, dynamically on pillar and the spring lever moving contact is arranged, it has return spring in the other direction, and moving contact one end is the switch that Chang Kai and normally closed two contacts are arranged.
The utility model compact conformation, cheap and result of use is better is applicable to the pressure control of water, oil, liquid, is specially adapted to the water side of fast heating type water heater, can reach the purpose that has water electricity to be arranged, cut the supply of water and electricity.
Fig. 1 is a structural representation of the present utility model;
Below in conjunction with accompanying drawing structure of the present utility model and operation principle are described in more detail.
As shown in Figure 1, comprise shell 1, barrier film 2, sealing ring 6, activity capping 4, piston 3, spring 7, dynamic pillar 8, return spring 9, lever moving contact 10 and the switch that constitutes by supply terminals 13, normally-closed contact 12 and normally opened contact 11 in the structure of the present utility model with the barrier film one; To be medium entered the enclosure space 5 between barrier film and the shell and produced certain pressure by the medium inlet 14 of outer casing underpart its operation principle, when pressure raises, promote to move on the barrier film, cause that moving piston on the piston 3 promotes dynamic fulcrum 8 and make lever moving contact 10 action, supply terminals 13 and normally-closed contact 12 are broken away from, contact with normally opened contact 11, reach the purpose of control circuit action, when pressure medium descends, because the effect of return spring sets back the contact.
