Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 shows a mode of execution of the utility model Electromagnetic Control stop valve, and it comprises that one disposes the valve body 15 of the stop valve of valve gap 12 on top, and this valve body respectively is provided with a water intake 20 and water outlet 22 on same shaft axis; One diaphragm assembly 10 is set between this valve body and this valve gap, wherein form center fenestra 101, generate a valve body epicoele 21 between this valve gap and the described diaphragm assembly, these diaphragm assembly 10 following configuration one supporting frames 11, this supporting frame 11 is supported on the top of described valve body 15; Referring to shown in Figure 1.
Device one valve rod 5 in the described valve gap 12, this valve rod 5 is by the Stem Mut 8 that is threaded, the interior edge face 121 corresponding cooperations of plane and described valve gap on this Stem Mut 8.
Periphery device one pressure spring 13 of described Stem Mut 8,10 groups of these pressure spring 13 lower ends and described diaphragms add to collide in the plane and connect that these pressure spring 13 upper ends are positioned on the inside locating slot 16 of described valve gap 12.
Valve rod 5 upper ends connect a handwheel 3, in order to the rotation of this valve rod of manual control.Along with the rotation of valve rod 5, drive Stem Mut 8 and move up and down along screw thread, when moving up, withstood by the corresponding interior edge face 121 of described valve gap 12 again by this Stem Mut, be able to the mobile position of control valve stem nut.Pack in the endoporus of valve rod 5 and tighten a thin bar 6, an exhaust nozzle 1 on the described valve rod is passed on the top of this thin bar 6, between this thin bar 6 and the exhaust nozzle 1 small sealing ring 2 is set, again with cap 23 lockings.
Valve rod 5 tops are provided with an elastic scheibe 4, and these elastic scheibe 4 lower planes contact with the end face of described valve gap 12.One side of this valve gap 12 is provided with the pilot hole 18 of a belt spool seat 14, and end device one solenoid valve 17 presents the cooperation of opening and closing on the pilot hole 18.Described diaphragm assembly 10 is provided with by-pass hole 19, and this by-pass hole 19 is connected with water intake 20, center fenestra 101, epicoele 21, pilot hole 18.
The utility model is owing to adopted the leading type electromagnet cut off valve structure of opening a pilot hole on valve body and valve gap, make as long as can utilize electromagnetic force to pick up the electromagnet of this pilot hole of switch once quite low power electric current to the solenoid valve supply, thereby reach the effect of Open valve, so it is low to consume energy.And as long as by cutting off electric current, solenoid valve will cut out pilot hole moment, thereby described in a short period of time stop valve is closed; Its process action is quick, is quick on the draw.
Electromagnetic valve switch signal of the present utility model can be connected with computer control, and is very convenient again.
Flow when the utility model can also be controlled described stop valve and opens by the handwheel on the rotary valve rod.
Working procedure of the present utility model is such:
First kind of operating mode is when solenoid valve enters cut-off state
When the no electric circuit of solenoid valve 17, under the effect of magnet spring 24, solenoid valve magnet is close to valve core case 14, and pilot hole 18 is closed.At this moment, the pressure of water intake 20 is greater than the pressure of valve body epicoele 21, and fluid flows into valve body epicoeles 21 by by-pass hole 19 rapidly, is zero up to the upper and lower pressure difference of diaphragm assembly 10.Close described stop valve because the spring force effect promotion diaphragm assembly of spring 13 moves down this moment, makes stop valve be in normally off, sees Fig. 2.
Second kind of operating mode is when solenoid valve enters opening state
When described solenoid valve 17 is switched on,, solenoid valve magnet overcomes the elastic force of magnet spring 24, and then the pilot hole 18 on the valve gap 12 is opened.At this moment, zone between valve body and described valve gap is that valve body epicoele 21 is connected by pilot hole 18 with water outlet 22, the pressure of epicoele 21 is dropped rapidly to water outlet 22 and equates, because the pressure of water intake 20 is greater than the pressure of valve body epicoele 21 at this moment, so low high pressure reduction on around the diaphragm assembly, forming, the spring pressure that hydrodynamic pressure promotion diaphragm assembly overcomes spring 13 moves up, till being withstood described valve gap interior edge face 121 by Stem Mut 8, open described stop valve, make valve be in opening state.Fluid flows directly into water outlet 22 from water intake 20 through described diaphragm assembly 10 belows, sees Fig. 1.
The third operating mode, the flow when the described stop valve of manual tune is opened, and manually control described stop valve open and-shut mode
When Stem Mut 8 is blocked by valve gap in sense of rotation; At this moment, handwheel 2 drives valve rods 5 rotations, because this valve rod and Stem Mut be with being threaded, Stem Mut promptly moves up and down.When described stop valve is opened, head on diaphragm assembly 10 by Stem Mut and move down, the flow when controlling described stop valve and opening.When Stem Mut withstands on valve body lower portion to diaphragm assembly 10 fully, can reach the effect of closing described stop valve.
The utlity model has following advantage: the first is reasonable in design, and is simple in structure, and volume is little; It two is easy for installation, and control system is simple, is convenient to be connected with computer; Its three be that action is quick, power is little and effectively overcome electromagnet cut off valve since in the long-time running sealing loss of valve rod cause leakage problem now.
Now assembly process of the present utility model is described below:
With reference to shown in Figure 1, aim at supporting frame 11, diaphragm assembly 10 on the valve body 15 that is placed on stop valve successively; Spring 13 is put on the diaphragm assembly 10; " O " RunddichtringO 7 is assembled on the valve rod 5, again Stem Mut 8 is screwed on the valve rod 5; Then, the valve rod 5 of band Stem Mut 8 is aimed at rigging position be assembled on the valve gap 12, this valve rod 5 is blocked on the described valve gap 12 that is positioned at an elastic scheibe 4 again; With valve core case 14, catheter, install to respectively on the valve gap 12, at last the valve gap 12 that assembles is assembled on the valve body 15 again, with bolt 9 valve gap 1 and valve body is tightened and be integral with solenoid valve 17.
