Abstract
The utility model relates to a high water pressure switch which comprises a base, an upper cover, a membrane, a high pressure pressing plate, a high pressure spring-board and an inching switch, wherein a movable cavity is formed on the lower end portion of the high pressure spring-board corresponding to the membrane part, a holder in a reversed 'T' shape is arranged in the movable cavity, the upper end portion of the holder is adjacent with the lower end of the high pressure spring-board, and the lower end portion of the holder is adjacent with the lower end surface of the membrane. A convex part on the high temperature spring-board in the prior art is removed, the holder in a reversed 'T' shape is arranged in the high pressure spring-board and the membrane, since the area on the lower end portion of the holder is rightly consistent with the membrane area on the lower portion, when water enters a water pressure cavity under the membrane, the membrane is deformed and pushed upwards to push the holder to move upwards, the holder further enables the high pressure spring-board to act and contact a switch contact of the inching switch, since the membrane is deformed normally, the membrane can not damage easily, the upper end portion of the holder is in a circular arc shape, the area contacting the high pressure spring-board is small, the action force is big, and the high pressure spring-board works better.
Description
Technical field
The utility model relates to a kind of high hydraulic pressure switch.
Background technology
As shown in Figure 1, high hydraulic pressure switch is by base, loam cake, diaphragm, the high pressure pressing plate, the high pressure springboard, parts such as sensitive switch are formed, the edge laterally offered aquaporin in the base, above crossing the aquaporin stage casing, offer the hydraulic pressure chamber, the hydraulic pressure chamber is communicated with the mistake aquaporin by pressure port, diaphragm arrangement is in the top in hydraulic pressure chamber, form working chamber in the loam cake, sensitive switch is arranged in the working chamber, the high pressure pressing plate is arranged on loam cake bottom, loam cake is fixedlyed connected with base by the high pressure pressing plate, corresponding diaphragm forms movable span on the high pressure pressing plate, the high pressure springboard that is the T type is arranged in the working chamber movably, be between high pressure pressing plate and the sensitive switch, high pressure springboard right-hand member is hinged on and covers, and the protuberance of high pressure springboard lower end stretches in the movable span of high pressure pressing plate and with the diaphragm close neighbour and is provided with, and the upper surface of high pressure springboard contacts with the switch contact of sensitive switch.Because high pressure springboard right-hand member is hinged, protuberance activity on it for convenience, it is bigger that the movable span of high pressure pressing plate must be offered, thereby between diaphragm, high pressure pressing plate, high pressure springboard three, form bigger cavity, when water during from the crossing aquaporin and pass through of base, push up on the diaphragm pressurized, diaphragm does not all contact with protuberance in the high pressure springboard, the part of diaphragm can be extruded in the cavity, time one is long, cause the diaphragm wearing and tearing, even damage, cause whole high hydraulic pressure switch to reduce useful life.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and longer high hydraulic pressure switch of a kind of life-span is provided.
For achieving the above object, the utility model adopts a kind of high hydraulic pressure switch, comprise base, loam cake, diaphragm, the high pressure pressing plate, the high pressure springboard, sensitive switch, the edge laterally offered aquaporin in the base, above crossing the aquaporin stage casing, offer the hydraulic pressure chamber, the hydraulic pressure chamber is communicated with the mistake aquaporin by pressure port, diaphragm arrangement is in the top in hydraulic pressure chamber, form working chamber in the loam cake, sensitive switch is arranged in the working chamber, the high pressure pressing plate is arranged on loam cake bottom, loam cake is fixedlyed connected with base by the high pressure pressing plate, corresponding diaphragm forms movable span on the high pressure pressing plate, the high pressure springboard is arranged in the working chamber movably, be between high pressure pressing plate and the sensitive switch, high pressure springboard right-hand member is hinged on and covers, the upper surface of high pressure springboard contacts with the switch contact of sensitive switch, sensitive switch is connected by high pressure springboard and diaphragm formation, the corresponding diaphragm portion in high pressure pressing plate bottom forms movable chamber, be provided with the holder that is inverted T shape in the movable chamber, holder upper end and high pressure springboard lower end close neighbour, the upper surface close neighbour of holder bottom and diaphragm.
The utility model further is set to the holder upper end again and is circular-arc.
The utility model removes the ledge on the high pressure springboard of the prior art, the holder that is inverted T shape is set between high pressure springboard and diaphragm, because the bottom area of holder is just in time consistent with the diaphragm area of below, in water enters into the hydraulic pressure chamber of diaphragm below, make on the diaphragm deformation and push up, promote to move on the holder, holder makes the action of high pressure springboard again, touch the switch contact of sensitive switch, because diaphragm deformation is normal, not fragile, and the holder upper end is circular-arc, little with high pressure springboard contact area, active force is big, makes the work of high pressure springboard good.
