Abstract
The utility model provides an electric pilot valve comprising a main valve and a pilot valve body, wherein the main valve divides the valve into a water inlet pressure area, a water outlet pressure area and an upper cavity through membranes. The main valve controls pressure of the upper cavity through opening and closing of the pilot valve body. A micro electric pilot valve including a micro electric ball valve, a micro electric check valve and an electric ceramic chip valve serves as the pilot valve body so as to control the opening and the closing of the main valve. The electric pilot valve has the advantages that power consumption is low, when the valve is opened or closed at voltage of 5V, conduction time is less than 8 seconds and the current is less than 100mA; efficiency is high and time of opening and closing the valve is less than 5 seconds; and service life is as long as 100 thousand times. The electric pilot valve can be widely used in industrial control and civil control.
Description
Technical field: the utility model relates to a kind of electric control valve, particularly a kind of electric guide valve.
Background technique: electric control valve is the most frequently used control unit in modern industry and civilian control, because its on-off mode is superior, at present in a large number for the switch valve of heavy caliber fluid hose.At present, the most frequently used have electromagnetic pilot valve and a large class of electric valve two, and electromagnetic pilot valve has the characteristics such as open and close are rapid, driving moment is little, long service life, but exist power consumption large, can not self-insurance and the problem such as easily be disturbed; And electric valve (comprising: electric ball valve, electric butterfly valve, electric gate valve) have can self-insurance and the characteristics such as antijamming capability is strong, but have the problems such as energy consumption is high, the open and close time is long, driving moment is large, working life is short.
Summary of the invention: the design has carried out organic combination by two kinds of valves, has developed advantage separately, for the broader applications of electric control valve provide may.
The utility model comprises main valve and pilot valve two large divisions; Main valve adopts solenoid valve main body, guide's part small-sized electric ball valve; Main valve comprises lower support frame, secondary spring on main valve body, diaphragm, diaphragm, diaphragm is positioned at the main valve body middle part, upper and lower respectively have a support, above the diaphragm upper bracket, be secondary spring, diaphragm has been divided into valve cavity intake pressure district, discharge pressure district and three parts of epicoele under the spring force effect; Pilot valve one end is connected with the discharge pressure chamber by leak-off pipe, and the other end is communicated with the pilot hole on main valve body by connector, and pilot hole one end of opening on main valve body is communicated with by flow regulator pieces with the intake pressure chamber, and the other end is communicated with epicoele; Pilot valve adopts the miniature electric valve.
Pilot valve can be miniature electric ball valve, miniature electric break valve or electric ceramic chip valve.
Main valve is controlled upper cavity pressure by the open and close of pilot valve, and when pilot valve opens, epicoele and exhalant region are communicated with, and realize pressure release, and now diaphragm lifts under the effect of inhalant region pressure, main valve open; When pilot valve is closed, epicoele and exhalant region disconnect, and epicoele reaches isobaric by pilot hole and inhalant region, and diaphragm moves down the cut-out entery and delivery port under this pressure-acting, and main valve is closed.
Owing to adopting technique scheme, the utlity model has low power consumption (be less than 8s current"on"time during the open and close valve under 5V voltage, electric current is less than 100mA); High efficiency (the open and close valve time is less than 5s); The advantage of long lifetime (being greater than working life 100,000 times).
The accompanying drawing explanation: Fig. 1 is structural representation of the present utility model.
Embodiment: as shown in Figure 1, model utility comprises main valve 1 and pilot valve 10 two large divisions, main valve is divided into intake pressure chamber, discharge pressure chamber and three parts of epicoele by diaphragm 5 by valve, and diaphragm respectively has a support 7,6 up and down, and secondary spring 8 is for fixing diaphragm.Main valve is controlled upper cavity pressure by the open and close of pilot valve 10, when pilot valve 10 opens, the water in the intake pressure chamber enters epicoele through pilot hole 3, flow regulator pieces 4 and the discharge pressure chamber is communicated with, and realizes pressure release, diaphragm 5 opens under the effect of intake pressure cavity pressure, main valve open; When pilot valve 10 is closed, epicoele and discharge pressure chamber disconnect, and epicoele reaches isobaric by pilot hole and intake pressure chamber, under the pressure difference effect of diaphragm 5 by epicoele and discharge pressure chamber, turn-offs intake-outlet, and main valve is closed.Pilot valve 10 1 ends are by leak-off pipe 11 and discharge pressure chamber, the other end is communicated with pilot hole 3 by connector 9, pilot valve 10 is selected the miniature electric valve, can be miniature electric ball valve, miniature electric break valve or electric ceramic chip valve, in order to control the open and close of main valve.
Claims (2)
1. an electric guide valve, by main valve and pilot valve two-part, formed, it is characterized in that: main valve comprises lower support frame, secondary spring on main valve body, diaphragm, diaphragm, diaphragm is positioned at the main valve body middle part, upper and lower respectively have a support, above the diaphragm upper bracket, be secondary spring, diaphragm has been divided into valve cavity intake pressure district, discharge pressure district and three parts of epicoele under the spring force effect; Pilot valve one end is connected with the discharge pressure chamber by leak-off pipe, and the other end is communicated with the pilot hole on main valve body by connector, and pilot hole one end of opening on main valve body is communicated with the intake pressure chamber by flow regulator pieces, and the other end is communicated with epicoele; Pilot valve adopts the miniature electric valve.
2. according to the described a kind of electric guide valve of claim, it is characterized in that: pilot valve can be miniature electric ball valve, miniature electric break valve or electric ceramic chip valve.
