The utility model has the advantages of the simple structure, the easy production and assembly, the low failure rate, the good stability, the high compressive resistance, the small volume and the large flow rate, and thereby can be widely used to control the flow of various liquid and gas.
Description
Technical field
The utility model belongs to fluid control field, relates to a kind of solenoid controlled pilot valve that is used on the tap water water meter.
Background technique
At present, domestic employing pilot valve is widely used in various fluids, gas flow control.Forms such as that its controlling method has is manual, pneumatic, hydraulic pressure, magnetic control.In existing known technology, magnetic control system pilot valve is that the employing coil produces magnetic field by electric current, drives the sliding axle motion that tooth bar is arranged, and the rack drives gear rotates, and the gear driven eccentric wheel rotates, and the eccentric wheel drive is stuck up bar and moved up and down start or stop water inlet and outlet aperture.The valve of this structure when there is the current process inside, rushes down to press by the control aperture and alleviates the stifled pressure of valve, makes valve open or closes.There are structure problems such as complexity, part requirement machining accuracy height, assembling difficulty, poor stability, rate of fault height, compressive resistance be low, so in production practices, can't use.
Summary of the invention
The purpose of this utility model is for overcoming the problem that above-mentioned known technology exists, providing a kind of electromagnet simple in structure, highly sensitive, that rate of fault is low to control pilot valve.
The utility model solenoid controlled pilot valve content Description:
The utility model solenoid controlled pilot valve, by: power supply, reverser, enclosed cavity, spool, water inlet aperture pipe, ostium excurrens pipe, filter screen, leather cup are formed, it is characterized in that: in the enclosed cavity of solenoid controlled pilot valve, spool is set, the left side of enclosed cavity has into, and water aperture pipe communicates with the water inlet main pipe, the right side has the ostium excurrens pipe to communicate with the water outlet main pipe, the centre has the leather cup chamber of a through hole below enclosed cavity to communicate, and in the water inlet of water inlet aperture pipe filter screen is set; Sliding axle in the spool, pressure spring is caught on for sheet has a hook groove in its front portion, and the rear portion is cylindrical, and interior edge magnet, sliding axle are contained in the interior pipe of coil, can horizontally slip under the effect in magnetic field; One end of spring is fixed on the support, and the other end is pressed in by sliding axle hook groove and sticks up on the bar, and can horizontally slip, and makes that to stick up bar be up and down tilting of center with the bearing pin.
The utility model solenoid controlled pilot valve, simple in structure, making is assembled easily, rate of fault is low, good stability, compressive resistance height, volume is little, flow is big, start or stop speed only is 0.01% second, energy-conservation, characteristics that cost is low soon, can be widely used in various fluids, gas flow control.Adopting the 3V high power lithium battery is the energy that electromagnetism produces, have that energy is big, service time long, etc. advantage.

Embodiment
The utility model solenoid controlled pilot valve is achieved in that to do below in conjunction with accompanying drawing and specifies.See Fig. 1, in the enclosed cavity 3 of solenoid controlled pilot valve, spool 4 is set, the left side of enclosed cavity 3 has into, and water aperture pipe 5 communicates with the water inlet main pipe, the right side has ostium excurrens pipe 6 to communicate with the water outlet main pipe, the centre has the leather cup chamber of the leather cup 9 of a through hole 7 below enclosed cavity 3 to communicate, and in the water inlet of water inlet aperture pipe 5 filter screen 8 is set; Sliding axle 11 in the spool 4, pressure spring 13 is caught on for sheet has a hook groove in its front portion, and the rear portion is cylindrical, and interior edge magnet, sliding axle 11 are contained in the interior pipe of coil 10, can horizontally slip under the effect in magnetic field; One end of spring 13 is fixed on the support 14, and the hook groove of the other end by sliding axle 11 is pressed in and sticks up on the bar 12, and can horizontally slip, and makes that to stick up bar 12 be center tilting up and down with the bearing pin.
Working procedure:
Connect power supply 1 and adjust reverser 2, it is opposite with sliding axle 11 internal magnetic poles to make coil 10 produce field pole, sliding axle 11 is attracted to ostium excurrens 6 directions together with spring 13, sticks up bar 12 and seal ostium excurrens 6 under the pressure of spring 13, opens into water aperture 5 simultaneously, water enters enclosed cavity 3 from water inlet aperture 5, and entering the leather cup chamber by enclosed cavity 3 and leather cup chamber through hole 7, leather cup 9 produces under the effect of negative pressure at self elastic force and fluid, moves downward, the sealing main channel, valve closing.
Rotate reverser 2, the magnetic field that coil 10 is produced is identical with sliding axle 11 internal magnetic poles, and sliding axle 11 is pushed to into water aperture 5 directions together with spring 13, sticks up bar 12 and lives in water aperture 5 in the pressure lower seal of spring 13, opens ostium excurrens 6 simultaneously.Leather cup 9 produces under the acting in conjunction of negative pressure at hydraulic pressure and fluid, moves upward, and the water in the leather cup chamber is forced out (extraction), and discharges by enclosed cavity 3, draining aperture.Leather cup 9 arrives position shown in dotted lines in Figure 1, valve open.
