Description
Technical field
The utility model relates to a kind of pressure switch, particularly a kind of dish-shaped shell fragment auto-pressure switch.
Background technology
The auto-pressure switch of the dish-shaped shell fragment of existing band relies on pressure to promote dish-shaped shell fragment, and when dish-shaped shell fragment is subject to certain pressure, projecting surface depressed deformation promotes thimble, and thimble backs down shell fragment thus disconnects contact point, and switch disconnects; Distress resolves or when reducing to certain value, dish-shaped shell fragment projecting surface return, shell fragment promotes thimble reduction thus drives contact point return, and switch closes.Its weak point is: when producing dish-shaped shell fragment, its thickness and projecting surface height determine pressure and pressure extent, can not adjust again after product approval, dish shell fragment projecting surface is under pressure to concave surface and can not be badly deformed, switch contact easily plays spark, loose contact, break distance is inadequate, the requirement of pressure regulation power and pressure reduction in big-and-middle-sized pressure switch can not be met, contact point break distance is little, easily plays spark, makes switch loose contact, useful life, at 30,000 times, affects switching stability and useful life.Existing big-and-middle-sized switch is due to needs adjustment pressure magnitude of pressure differential, and useful life, so need many group springs and metal parts to coordinate, very heavy, manufacturing cost was high at 200,000 times.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, and it is practical to provide one to meet various big-and-middle-sized auto-pressure switch instructions for use, and structure is simple, the dish-shaped shell fragment auto-pressure switch of low cost of manufacture.
The purpose of this utility model is achieved in that
A kind of dish-shaped shell fragment auto-pressure switch, comprise connector, dish shell fragment, switch pedestal, switch housing, wiring frame, dish shell fragment spring, dish shell fragment spring lower seat, thimble, copper splinter, silver point, lug plate, compression spring, pressure spring, it is characterized in that switch pedestal has dish-shaped shell fragment spring, dish shell fragment spring upper end is provided with dish-shaped shell fragment and dish-shaped shell fragment protruding parts is downward, dish shell fragment spring bottom is provided with dish-shaped shell fragment spring lower seat, compression spring is provided with in switch pedestal, one end is placed in above dish-shaped shell fragment spring lower seat, the other end is pipe regulating screw nut, pressure spring is arranged in wiring frame, top is pressure reduction adjusting nut, bottom is pressed in pressure reduction thimble top, pressure reduction thimble bottom is placed in above dish-shaped shell fragment concave surface, do not contact concave surface.
The utility model is owing to adopting above architecture advances, and during use, the pressure entered from connector promotes dish-shaped shell fragment spring lower seat and moves up.Dish shell fragment spring is compressed.Dish-shaped shell fragment convex surface can be moved to concave surface when being compressed to elastic force, concave surface boosts thimble, and thimble boosts copper splinter, copper splinter drives silver point power-off, now extraneous pressure stops, and dish-shaped shell fragment is not pulled to the required separation distance of oneself convex surface to concave surface rapid deformation, and silver point is struck sparks.This dish-shaped shell fragment spring, when external pressure stops, being badly deformed dish-shaped shell fragment projecting surface fast with the elastic force of self to concave surface.Boost thimble, thimble boosts copper splinter.Copper splinter drive silver point is opened completely, power-off, when external pressure progressively reduces, dish shell fragment spring lower seat moves down, dish shell fragment spring elongates, when be elongated to elastic force be less than dish-shaped shell fragment concave face to projecting surface distortion needed for power time, concave surface is upspring to convex surface fast, and at this moment the elastic force of copper splinter depresses thimble, drive silver point to close, switch is energized simultaneously.Regulate compression spring coefficient of elasticity, namely adjustable compression spring is to the pressure size of dish-shaped shell fragment spring lower seat, thus pressure size during by-pass cock work.Regulate the coefficient of elasticity of pressure spring, the pressure size to pressure reduction thimble can be changed, have also been changed pressure reduction thimble to the power size of dish-shaped shell fragment concave surface to convex surface resilience simultaneously, thus magnitude of pressure differential during by-pass cock work, only need utilize dish-shaped shell fragment, dish-shaped shell fragment spring, dish-shaped shell fragment spring lower seat, compression spring, pressure spring, with the use of, the utility model can meet various large, medium and small auto-pressure switch instructions for use, practical, low cost of manufacture.

Embodiment:
Now by reference to the accompanying drawings the utility model is described in detail.
As shown in Figure 1, Figure 3, a kind of dish-shaped shell fragment auto-pressure switch.
Comprise: connector 1, diaphragm seal 2, pressing plate 3, dish shell fragment spring lower seat 4, dish shell fragment spring 6, the dish shell fragment spring seat of honour 7, upper cover for seat 8, dish shell fragment 9, thimble 10, compression spring 5, pressure spring 29, compression bolts 12, pressure reduction bolt 30, lug plate 13, lug plate framework 17, switch housing 14, switch press plate 16, shift knob 15, single armed 18, copper splinter 11, silver point 20, exhaust depression bar 21, Pressure-bar spring 22, line card 23, line card nut 24, switch pedestal 25, vent valve 27, exhaust needle 26, pressure reduction thimble 28, single armed pin 19.
