Description
The utility model relates to bidirectional electromagnetic valve.
At present, the general electromagnetic valve of Shi Yonging, majority is unidirectional conducting, or two-way shut-off valve.China announced that a notification number was 88210090 two-way anti-explosion is electromagnetic stop valve in 1988, and two spools and valve seat are arranged in its valve body, and the keying of valve attracts valve rod or spring to promote spool by electromagnetic coil to realize downwards.This electromagnetic valve structure complexity is used inconvenient.
The purpose of this utility model is to provide a kind of bidirectional electromagnetic valve of simple in structure, hydraulic control.
For achieving the above object, the technical solution adopted in the utility model: below the general solenoid valve calutron, establish a pressure-releasing chamber of forming by gland and valve gap, the roof of described gland is provided with guide hole on the medium, the sidewall of described gland respectively is provided with a water conservancy diversion piston, this water conservancy diversion piston is connected with medium channel, this medium channel communicates with guide hole on the medium, and be provided with the pressure release import, one end guide hole on medium of the iron core of calutron stretches into this pressure-releasing chamber, and it is corresponding with guide hole on the medium to be provided with the sealing plate that can move up and down with iron core at this end of iron core, and also be provided with the pressure relief device that can move up and down with iron core, this pressure relief device is by the body of band medium channel, and the pressure release piston that is divided into the body both sides is accordingly formed, each pressure release piston all communicates with medium channel, and being provided with the pressure release outlet, this pressure release outlet is corresponding with above-mentioned pressure release import; Valve gap is provided with guide hole under the medium, and communicates with pressure-releasing chamber, and described valve gap and horizontal flashboard moving up and down are formed the lock chamber, and a side of horizontal flashboard is connected with spring, and opposite side is connected with perpendicular flashboard.
As a kind of improvement of the present utility model, the chamber wall of pressure relief device body and pressure-releasing chamber is the step type joining.
As another kind of improvement the of the present utility model, establish expansion screw at medium channel.
The utility model is work like this, when medium flows to the right side from valve body left side and need open a sluice gate, computer or manual command's electrical apparatus control equipment, make calutron produce electromagnetic force, iron core is moved up drive sealing plate and seal guide hole on the medium, move on the pressure relief device simultaneously, make pressure release outlet and the UNICOM relative of pressure release piston with the pressure release import of medium channel, but left side pressure release piston under pressure medium by press seal, simultaneously horizontal flashboard is and upwards moved by the pressure of left side medium, order about and move the stick harness of washing right side pressure release piston open on the medium in the lock chamber, make medium in the lock chamber from the pressure release of right side pressure release piston outlet, the pressure release import that enters medium channel, and flow to the valve body right side from medium channel and realize pressure release, make on the horizontal flashboard and move on the moving perpendicular flashboard of shipper pole, open a sluice gate.When needs block, stop electromagnetic force, under pressure medium and action of gravity, iron core moves down, and drives sealing plate and moves down, simultaneously, pressure relief device moves down, the pressure release outlet of pressure release piston and the pressure release import of medium channel are staggered, and medium is guide hole on medium, flow into pressure-releasing chamber, and guide hole flows into the lock chamber under the medium of valve gap, order about horizontal flashboard and move down, perpendicular flashboard is moved down, realize damming.As a same reason, when medium flows to the left side from the valve body right side, also can realize open and close control, thereby realize two-way admittance control by above-mentioned reason, simple in structure.In addition, expansion screw is set on medium channel, regulates rate-of flow, regulate flashboard and close, open speed.
Below in conjunction with the drawings and the specific embodiments the utility model is elaborated:
Fig. 1 is the utility model solenoid valve front elevational schematic.
As shown in Figure 1, the utility model comprises valve gap 4, valve body 1, calutron 2, below calutron 2, establish a pressure-releasing chamber 5 of forming by gland 3 and valve gap 4, on the roof of pressure-releasing chamber 5, have guide hole 51 on the medium, the medium channel 63 of on the chamber wall of pressure-releasing chamber 5 center line both sides, respectively establishing a water conservancy diversion piston 6 accordingly and being connected with water conservancy diversion piston 6, on medium channel 63, can be provided with expansion screw 7, regulate the flow of medium.Water conservancy diversion piston 6 is made up of stick harness 61 and spring 62, the size of stick harness 61 will suit, the intensity of spring 62 also will suit, when needing, the stick harness 61 of a water conservancy diversion piston 6 can be washed open by medium, make medium when water conservancy diversion piston 6 flows through, and the stick harness of opposite side water conservancy diversion piston can effectively be blocked its medium channel.On medium channel 63, respectively establish a pressure release import 64.On the roof of pressure-releasing chamber 5, be provided with guide hole 51 on the medium, communicate with medium channel 63, one end of the iron core 10 of calutron 2 guide hole 51 on medium stretches into pressure-releasing chamber 5, on iron core 10, be provided with the sealing plate 52 that can move up and down with iron core 10, sealing plate 52 is corresponding with guide hole 51 on the medium, and its size will suit, and both can effectively block guide hole 51 on the medium, when needing, can remove again and allow medium flow into pressure-releasing chamber 5.Also be provided with the pressure relief device 9 that can move up and down with iron core 10 at iron core 10 these ends, this pressure relief device 9, form by the body 91 of band medium channel 55 and corresponding two the pressure release pistons 92 that are positioned at body 91 center line both sides, body 91 can be the identical cylinder of diameter up and down, also can be up and down, diameter successively decreases into step type, in this case, supporting body 91 pressure-releasing chamber chamber walls also for its merge mutually step-like.Pressure release piston 92 bottoms are connected with medium channel 55, and establish pressure release outlet 93 at an upper portion thereof, and pressure release outlet 93 is corresponding with above-mentioned pressure release import 64.The position and the position of sealing plate 52 on iron core 10 of pressure release outlet 93 adapt, when sealing plate 52 is sealed on the medium guide hole 51, pressure release outlet 93 communicates with pressure release import 64, when otherwise sealing plate 52 leaves on the medium guide hole 51, pressure release outlet 93 is staggered mutually with pressure release import 64, pressure release piston 92 is made up of spring 921 and plunger 922, and spring 921 intensity sizes, plunger 922 sizes also will suit.Valve gap 4 is provided with guide hole 41 under the medium, guide hole 41 communicates with pressure-releasing chamber 5 under the medium, valve gap 4 is formed lock chamber 84 with horizontal flashboard 81, horizontal flashboard 81 capping valve ports 85, and bear pressure medium in the valve body 1, and horizontal flashboard 81 1 sides are connected with spring 83, and opposite side is connected with perpendicular flashboard 82, for strengthening effect, can be provided with the groove that moves up and down for perpendicular flashboard 82 at valve body 1 wall.Between perpendicular flashboard 82 and the valve body 1, between horizontal flashboard 81 and the valve body 1, can establish Sealing between pressure relief device 9 and the pressure-releasing chamber 5 chamber walls, prevent the medium seepage.
