Abstract
The invention discloses a pressure adjustable switch which comprises an adjusting screw, a spring, a push rod, a diaphragm, an air inlet, a microswitch and a shell, wherein one side of the microswitch is provided with the shell, the adjusting screw is arranged in the shell, the outer part of the adjusting screw is provided with the spring, the push rod is arranged at one side of the adjusting screw, the lower end of the push rod is provided with the diaphragm, and the lower end of the diaphragm is provided with the air inlet. The pressure adjusting switch of the design has high sensibility, a good automation control effect and small mechanical shock, and stably and reliably operates; and the pressure adjusting switch has a small volume and is low in cost, thereby having a wide application scope.
Description
Technical field
The present invention relates to a kind of adjustable pressure switch.
Background technology
Society is for adapting to modern step now, and a lot of factories have all adopted streamline production, make large-scale batch production become possibility, and human daily life environment is also progressively to automation and intelligent direction development; Make pressure switch at water power, running water, oil; Chemical industry, machinery, industries such as hydraulic pressure all can be used; But the pressure switch mechanical shock on the market is big, and output capacity is little, and cost height and sensitivity are not high; If when pressure changes, also need change trouble very to pressure switch.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of simple in structure in order to solve the deficiency of prior art, and volume is little, and cost is low, and is highly sensitive, and mechanical shock is little, can realize adjusting and the effective adjustable pressure switch of automation control to pressure.
Technical scheme: in order to realize above purpose, a kind of adjustable pressure switch of the present invention, it comprises: adjustment screw, spring, push rod; Diaphragm, air inlet, sensitive switch and housing; One side of described sensitive switch is provided with housing, is provided with adjustment screw in the housing, and the outside of described adjustment screw is provided with spring; One side of adjustment screw is provided with push rod, and the lower end of described push rod is provided with diaphragm, and the lower end of described diaphragm is provided with air inlet.
Described push rod is provided with slurcam, and described slurcam and sensitive switch offset.
Beneficial effect: a kind of adjustable pressure switch provided by the invention, when system gas pressure surpassed the spring setting pressure, diaphragm promoted to move on the push rod and makes sensitive switch cut off or connect circuit; The pressure regulating switch of this design is highly sensitive, and automation control is effective, and mechanical shock is little; Working stability is reliable; And because volume is little, cost is low, so applied widely.
Description of drawings
Fig. 1 is a full sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
As shown in Figure 1, a kind of adjustable pressure switch of the present invention, it comprises: adjustment screw 1, spring 2, push rod 3, diaphragm 4, air inlet 5, sensitive switch 6 and housing 7.
One side of described sensitive switch 6 is provided with housing 7; Be provided with adjustment screw 1 in the housing 7; The outside of described adjustment screw 1 is provided with spring 2, and a side of adjustment screw 1 is provided with push rod 3, and the lower end of described push rod 3 is provided with diaphragm 4; The lower end of described diaphragm 4 is provided with air inlet 5, and slurcam 8 and sensitive switch 6 that described push rod 3 is provided with offset.
When system's air pressure is imported and acted on the diaphragm 1 by air inlet 5; When system gas pressure surpasses the setting pressure of spring 2; Diaphragm 1 promotes to move on the push rod 3, and then drives that slurcam 8 moves up and the sensitive switch that offsets 6 is triggered, and makes to connect or disconnect circuit.
When needs are regulated pressure switch, adjustment screw 1 regulated getting final product.
The pressure regulating switch of this design is highly sensitive, and automation control is effective, and mechanical shock is little, and working stability is reliable, and because volume is little, cost is low, so applied widely.
Above-mentioned execution mode only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit is made according to the present invention or modification all should be encompassed within protection scope of the present invention.
