Abstract
The utility model discloses a fluid pressure-sensitive switch, belonging to a low-pressure switch. A thin film (4) and a flat washer (3) are installed in a supporting body (2) and are tightly pressed out by a clamping ring screwed in the supporting body (2) and installed into a movable ring (10), a movable body (9) is screwed in a switch body (6), after installed on a supporting base (5), a whole is screwed in the supporting body (2), a single-phase live wire is welded on the movable body (9), a zero line is welded on a movable ring (10), a conducting wire (10) is sheathed in a sealed ring (7) and is pressed out by a clamping screw cap, and the supporting body (2) is installed on a three-way piece of a liquid (gas) pipeline. When weak pressure exists in the liquid (gas) pipeline, a starting circuit is conducted, when no pressure exists in the pipeline, the switch is off, and the utility model is suitable for various high and low liquid (gas) switches with corrosivity.
Description
The utility model relates to the low pressure switch, particularly a kind of fluid pressure sensitive switch.
What use in the prior art is that this Pressure gauge sensitivity is low, the cost height through the Pressure gauge after improving.
The purpose of this utility model is: a kind of fluid pressure sensitive switch is provided, it is installed in the ducted threeway, make the starting switch of low pressure magnetic switch, when liquid (gas) body has faint pressure in pipeline, its pressure acts on film, pass to active ring, make it to be closed, make the low-voltage starting circuit conducting with mobile; When in the pipeline during no faint pressure, because of the thrust of supporting mass, active ring is separated with mobile, switch opens circuit.
Formation of the present utility model: by compacting ring, supporting mass, plain washer, film, supporting base, switch body, active ring, mobile, sealing ring and clamping nut are formed, on supporting mass (2) endoporus stairstepping boss, film (4) and plain washer (3) are installed, cylindrical compacting ring (1) is screwed in supporting mass (2) upper screwed hole, compress plain washer (3) and film (4), the active ring (10) of on supporting mass stairstepping boss, packing into, again mobile (9) is screwed in the screwed hole of switch body (6), after loading onto the top supporting base of annular band (5), switch body (6) is screwed in the screwed hole of supporting mass (2) lower end, single-phase live wire is welded in the mobile (9), zero line is welded on the active ring (10), lead is inserted in the sealing ring (7), compress sealing ring (7) by clamping nut (8), in the threeway that screws into liquid (gas) body pipeline on the supporting mass (2).Compacting ring (1) cylindrical is made up of the two-stage cylinder, and external screw thread is arranged on the big column, and there is axially extending bore the centre.Supporting mass (2) is cylindrical, on the cylinder of upper end external screw thread is arranged, and the axial bore upper and lower side has internal thread, the stairstepping boss that middle oriented center line protrudes, and the upper surface of boss is made up of horizontal plane and inclined-plane.Switch body (6) is the two-stage cylinder, has external screw thread, centre that three grades of endoporus are arranged on large cylinder, on the big hole of upper end internal thread is arranged.
Compared with the prior art, the utility model is simple in structure, compact, cost is low, moves safe and reliable, life-span is long, and its sensitivity can be regulated arbitrarily, is applicable to various high and low liquid (gas) body, the various adverse circumstances work that sanies (gas) body is arranged have remedied the deficiency of low tension switch kind.
Accompanying drawing is the utility model structural representation.
Embodiment of the present utility model: as shown in drawings, film (4) and plain washer (3) are packed in the supporting mass (2), screwing in compacting ring (1) compresses, on supporting mass (2) the endoporus boss active ring (10) is installed, again mobile (9) is screwed in the switch body (6), after loading onto supporting base (5), the whole screw-in in the supporting mass (2).Single-phase live wire is welded in the mobile (9), and zero line is welded on the active ring (10), and lead is inserted in the sealing ring (7), compresses sealing ring (7) by clamping nut (8), in the threeway that screws into liquid (gas) body pipeline on the supporting mass (2).The fluid pressure sensitive switch is a kind of liquid, gas pressure sensitive switch.
Claims (4)
1, a kind of fluid pressure sensitive switch, by compacting ring, supporting mass, plain washer, film, supporting base, switch body, active ring, mobile, sealing ring and clamping nut are formed, it is characterized in that: on supporting mass (2) endoporus stairstepping boss, film (4) and plain washer (3) are installed, cylindrical compacting ring (1) is screwed in supporting mass (2) upper screwed hole, compress plain washer (3) and film (4), the active ring (10) of on supporting mass stairstepping boss, packing into, again mobile (9) is screwed in the screwed hole of switch body (6), after loading onto the top supporting base of annular band (5), switch body (6) is screwed in the screwed hole of supporting mass (2) lower end, single-phase live wire is welded in the mobile (9), zero line is welded on the active ring (10), lead is inserted in the sealing ring (7), compress sealing ring (7) by clamping nut (8), in the threeway that screws into liquid (gas) body pipeline on the supporting mass (2).
