Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, a kind of open type pressure control switch of the utility model, it comprises voltage regulation screw 1, inserted sheet assembly 2, pressure spring 3, base 4, diaphragm 5, conductive plate 6, tight loop 7, joint chair 8; Inserted sheet assembly 2 is made up of the inserted sheet contact, is installed on the both sides on the base 4, and joint chair 8 is arranged on base 4 belows; Joint chair 8 upper ends are provided with diaphragm 5; Diaphragm 5 upper ends are provided with pressure spring 3, and diaphragm 5 both sides connect conductive plate 6, and base 4 is connected fixing with joint chair 8 outsides through tight loop 7.Be divided into two cavitys through diaphragm 5 in the middle of base 4 and the joint chair 8, a side is that malleation chamber 10, opposite side are negative pressure cavity 11.Voltage regulation screw 1 is arranged on the upper end of pressure spring 3, and pressure spring 3, voltage regulation screw 1, conductive plate 6, inserted sheet assembly 2 are formed an annular seal space with diaphragm 5.One end protuberate basic unit 4 of inserted sheet assembly 2.As shown in Figure 2, the another kind of closed type pressure control switch of the utility model is provided with stage clip 9 in diaphragm 5 lower ends, can realize often opening and normally closed function.
The operation principle of open type pressure control switch: when the system that is controlled is malleation; Increase along with system's air pressure; Diaphragm 5 under the effect of air pressure with conductive plate 6 together to top offset, when conductive plate 6 contacts with inserted sheet assembly 2, switch conduction; The control system action no longer increases air pressure under set point; Along with the decline of air pressure, diaphragm 5 and conductive plate 6 are together to bottom offset, and conductive plate 6 breaks off with inserted sheet assembly 2, and the electric loop of system is broken off and counteragent increases system pressure once again, and so circulation repeatedly.Otherwise when working as the system that is controlled and being negative pressure, in like manner realize its control.
The operation principle of closed type pressure control switch: when the system that is controlled is malleation; Along with the increase of system's air pressure, diaphragm 5 under the effect of air pressure with conductive plate 6 together to bottom offset, when conductive plate 6 breaks off with inserted sheet assembly 2; Switch breaks off, the control system action; Along with the decline of air pressure, diaphragm 5 and conductive plate 6 are together to top offset, and conductive plate 6 and inserted sheet assembly 2 closures so circulate repeatedly.When the system that is controlled is negative pressure, in like manner realize its connecting and disconnecting function.
The utility model pressure control switch has multifarious connection and fixed form, and inserted sheet assembly 2 stretches out loam cake, can directly patch on corresponding sleeve, also can patch or be welded on the circuit board with corresponding connector.
The above is merely the preferred embodiment of the utility model, not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all is included within the protection range of the utility model.
