Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 show a mode of execution of the utility model deep well water pump control valve, it comprises that one has import 11 and the valve body 1 that exports 12, the leading truck 8 of import 81 and inner outlet 82 in valve rod 2 exterior arrangement one band, this leading truck fixing device is between the import 11 and outlet 12 of valve body, should interior import 81 communicate with valve body import 11, this inner outlet 82 is connected with valve outlet 12; This valve rod can slippage in leading truck 8 endoporus.
The be threaded inner concave shape flap 6 of a band flap pressing plate 9 of valve rod 2 tops, the outer rim lower plane of this flap 6 contacts with the last plane of valve rod 2.Valve rod 2 lower thread connect the guide rod 10 of a band seal ring 7, and sealing circle end face is corresponding with inner outlet 82, interior import 81 positions of leading truck; Pilot hole 13 phase configuration of guide rod 10 and valve body; Valve outlet 12 places are provided with a pressure feedback hole 14, and this pressure feedback hole is connected with leading truck 8 top through holes 16; Pilot hole 13 phase configuration of this guide rod 10 and valve body 1 bottom; The outer rim lower plane of this flap 6 contacts with the last plane of leading truck 8, reaches sealing effect.
The screw top of this valve body 1 connects a valve gap 3, and the plane is pressed mutually and touched on the outer rim of the lower plane of this valve gap 3 and flap 6.The screw top of this valve gap 3 connects an adjusting screw 31 that is used for conflicting spring seat 51; Install a spring 5 below the spring seat 51 and between the flap pressing plate 9; As shown in Figure 1.
The bottom of leading truck 8 is provided with the side and lets out hole 18, and it is corresponding with described seal ring 7 endface position that hole 18 is let out in this side.
The working procedure of the utility model deep well water pump control valve is as follows: when pump startup, under the effect of spring 5, spill flap 6 is in lowest order, seal ring 7 and leading truck 8 are maintained a certain distance, at this moment, the import 11 of valve is in outlet 12 and is communicated with opening state, and valve opening is so that discharging deep-well gas and fragment.After pump running steadily, the pressure at outlet 12 places slowly raises behind the valve, and act on by pressure feedback hole 14 below the barrier film of flap 6, overcome the elastic force of spring 5, the seal ring 7 and the distance of leading truck 8 are diminished, and keep stable, when flow rate changed, the variation of pressure caused the sealing gasket of valve internal and the distance of leading truck to change, when pressure becomes big, distance diminishes, and the flow that passes through diminishes; When pressure diminished, it is big that distance becomes, and it is big that the flow that passes through becomes; The pressure at outlet 12 places slowly raises behind the valve, and by pressure feedback hole 14 with fluid pressure action below the barrier film of flap 6, and overcome the elastic force of spring 5, make spill flap 6 drive flap pressing plates 9 and rise with valve rod 2; Then the distance between seal ring 7 and the leading truck 8 diminishes, and keeps stable.
The utility model just can guarantee that the pressure at valve export 12 places still can keep constant relatively under the situation of different demands when flow and pressure change.Force value can be adjusted the pretightening force adjusting of spring by the adjusting screw on the valve gap 3 31; After the adjusting, adjusting screw is locked with Cock screw.
The pressure of water keeps constant in system, and the demand of water is reduced even when not having demand, the pressure that acts on the flap below at outlet 12 places raises, and overcomes spring force, and valve 20 is closed.
The seal ring of leading truck of the present utility model and valve rod can not seal fully, and the flow rate that leaves a permission water is that the leading truck bottom sides of 1g/min～5g/min is let out hole 18, and it is corresponding with the endface position of seal ring 7 that hole 18 is let out in this side.Small current are filled into the pressurized tank 17 at valve export 12 places at leisure, and when the pressure of pressurized tank 17 was elevated to certain pressure at leisure, pressure switch 19 was closed; At this moment, the closing pressure of pressure switch must be higher than the constant pressure of valve setpoint; Make pump 15 quit work.When there was requirement in system again to water, the water of pressurized tank 17 slowly descended, and pressure switch 19 reopens, and pump 15 starts again; As shown in Figure 2.The operation of control valve 20 and pump 15 is to interact and interactional.The utility model can be regulated automatically, and when flow system flow changed, the pressure that can make valve downstream export 12 places kept constant.
