Below in conjunction with accompanying drawing, pressure electromagnetic valve for adjusting of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model pressure electromagnetic valve for adjusting.
Embodiment
As shown in Figure 1, the utility model pressure electromagnetic valve for adjusting comprises valve body 16 and valve gap 5, and wherein valve gap 5 is arranged on above valve body 16.Comprising valve body 16 top is working cavity 10, and valve body 16 bottom is divided into into water cavity 2 and water outlet cavity 14 by baffle plate 15.Be provided with water intake 3 in water inlet cavity 2, in water outlet cavity 14, be provided with water outlet 13.Water inlet cavity 2 be provided with opening above water outlet cavity 14 and be connected with working cavity 10.Septum assembly is provided with in working cavity 10.Septum assembly comprises barrier film 17 and connecting plate 18, its septation 17 selects plastic material, original shape can be automatically restored to when losing external force, barrier film 17 is laid on overthe openings, and be arranged on below connecting plate 18, connecting plate 18 left and right sides contacts with the sidewall of working cavity 10, is provided with and seals slide block 12 between connecting plate 18 and working cavity 10 sidewall.Pressure-detecting device 1 passes in the middle part of septum assembly.Pressure-detecting device 1 selects pressure transducer.Be provided with position-limit mechanism 4 in the middle part of pressure-detecting device 1, position-limit mechanism 4 comprises two defining flanges, and two defining flanges contact with septum assembly upper and lower surface respectively, move up and down for driving septum assembly.Pressure-detecting device 1 lower end is stretched into in water cavity 2, is positioned in the groove 11 of processing bottom water cavity 2, and can moves up and down in groove 11.The magnetic barrier film clutch 7 of tool is connected with above pressure-detecting device 1.Barrier film clutch 7 top reaches outside valve gap 5 through the through hole that valve gap 5 has, and barrier film clutch 7 arranged outside has shell 6, and its shell 6 is fixed on above valve gap 5.Shell 6 is provided with electromagnetic equipment 8 and display device 9, wherein electromagnetic equipment 8 selects electromagnetic coil, and LCD display selected by display device 9.Electromagnetic equipment 8 moves up and down for driving barrier film clutch 7.
The working principle of the utility model pressure electromagnetic valve for adjusting is as follows: open display device 9, is detected by pressure-detecting device 1 pair of water intake 3 pressure, detects numerical value and will be presented on display device 9.When pressure reaches setting value, electromagnetic equipment 8 works, and makes barrier film clutch 7 upwards apply certain pulling force, pulls septum assembly to move upward.After septum assembly rises, there is certain deformation and opened by the opening of water inlet cavity 2 and water outlet cavity 14 in barrier film 17, the below that water flows through working cavity 10 septation assembly from water inlet cavity 2 is discharged to water outlet cavity 14, and the pressure in valve body 16 reduces gradually.When pressure meets setting value, barrier film clutch 7 and septum assembly transfixion, the pressure in cavity just no longer changes, and keeps constant.When needs valve body 16, electromagnetic equipment 8 makes barrier film clutch 7 apply certain thrust downwards, and drive septum assembly to move downward overthe openings, barrier film 17 restores to the original state and covered by opening.When electromagnetic equipment 8 is due to emergency situations power-off, the control that barrier film clutch 7 will lose septum assembly, barrier film 17 can return to original shape due to the performance of self, and covered by opening, valve body 16, prevents the generation of fortuitous event.
