Abstract
The utility model relates to an equipressure cavity electromagnetic dynamic flow regulating control valve, used for controlling the size and the open/close of the automatic flow control of gas and liquid, comprising an electromagnetic coil 1, a magnetic yoke positioned in the electromagnetic coil 1, a spring-returning valve core mechanism and a valve base, etc. The spring-returning valve core mechanism is arranged on the elongation line of the axial line of the magnetic yoke for forming open and close with the magnetic yoke. The magnetic yoke 2 is connected with the inner wall of the electromagnetic coil 1 by screws, the end of the magnetic yoke is provided with a screw-driving edge 3, and an o-shaped sealing ring 4 is provided between the magnetic yoke and the electromagnetic coil. The utility model has the advantages of high opening sensibility, good valve port sealing performance, high closing reliability, small operating mechanism energy consumption, low manufacturing and maintaining costs.
Description
[technical field]
The utility model belongs to solenoid valve and makes the field.
[background technique]
The solenoid valve that is used for fluid flow regulation control at present, the general structure that adopts as shown in Figure 1, yoke 11 is fixedly installed on the inwall of electromagnetic coil 12, and spool 13 covers on input hole 14 and the delivery outlet 15 simultaneously.The shortcoming that is provided with two aspects like this.One, because the axial position of yoke is unadjustable, the valve opening stroke can not be adjusted, and the function of opening and closing is only arranged, no flow automatic and adjustable function.Its two, when the valve input hole had fluid to enter, valve was closed under acting force of the spring, hydrodynamic pressure is opposite with acting force of the spring, so acting force of the spring must can be closed greater than hydrodynamic pressure.Otherwise during Open valve, electromagnetic force must overcome acting force of the spring, and valve can be opened.Such structure has increased the mechanical energy consumption of actuator without rhyme or reason, has strengthened the wearing and tearing of spool valve seat, and has made complex structure, has increased manufacturing and maintenance cost.
[the utility model content]
In view of the above shortcoming of prior art, the purpose of this utility model is a kind of solenoid valve that is used for fluid flow regulation control of design, makes it to overcome the above shortcoming of prior art.
The purpose of this utility model is to realize by following means.
Flow for gases and liquids is regulated its size of control automatically and is opened and closed, by electromagnetic coil, place the yoke in the electromagnetic coil, be provided with on the yoke axis elongation line and constitute compositions such as the spring return spool mechanism that opens and closes and valve seat with yoke, adopt scyewed joint between the inwall of described yoke and electromagnetic coil, the termination of yoke is equipped with and changes the edge of a knife, is provided with the O RunddichtringO between yoke and electromagnetic coil.
The utility model is opened highly sensitive, and sealing valve port is good, has the reliability of closing height, and actuator's power consumption is little, makes and the low advantage of maintenance cost.
[description of drawings]
Description of drawings is as follows.
Fig. 1 is the sectional view of prior art valve.
Fig. 2 is a sectional view of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.
As shown in Figure 2, by electromagnetic coil 1, adopt scyewed joint between the inwall of yoke 2 and electromagnetic coil 1, the termination of yoke is equipped with and changes the edge of a knife 3, is provided with O RunddichtringO 4 between yoke and electromagnetic coil and isolates leakage.Owing to just can change adjustment valve opening stroke with changing cutter rotation yoke, except that the function of opening and closing, adjust the yoke rotation by the positive and negative direction of the edge of a knife that changes that places the yoke top, power by the control electric current changes valve stroke, thereby reach the automatic control flow size, dynamic flow is realized stepless allotment function.
Can see also that in Fig. 2 spool 5 is wedge-like and covers on the delivery outlet 6.When electromagnetic coil 1 did not have electric current to pass through, spool was in closed condition under the active force that places equivalent pressure cavity 7 internal spiral springs 8.Fluid enters equivalent pressure cavity by input hole 9, because equivalent pressure cavity is with outside isolated, and the consistent and pressure balance of direction of the suffered closing pressure of valve and fluid pressure action power.So valve more becomes to closing closely and does not leak.Helical spring 8 active forces need only need not solve valve regulation and control and return shutoff stroke active force greater than hydrodynamic pressure; When electromagnetic coil is connected the control electric current, electromagnetic force absorption spool imposes reaction force to equivalent pressure cavity internal spiral spring, thereby cause the valve close mouth to form positive differential pressure with the outside to the moment that delivery outlet 6 leaks, pressure fluid is gushed out valve port, pressure disequilibrium in the equivalent pressure cavity, the positive differential pressure auxiliary electrical magnetic force of valve port moment formation imposes reaction force to helical spring simultaneously, causes valve to be opened into control range fast.
The utility model has tradition for the automatic control of the flow of middle high-pressure pressure fluid The not available unlatching sensitivity of magnetic valve and sealing valve port. Open the cross section with the traditional electrical magnet valve Long-pending on year-on-year basis: this valve has that volume is little, in light weight, compact conformation, close reliability height, saving Electric energy, make that raw materials consumption is few, the characteristics of low cost of manufacture and greatly reduce linear quadratic control Thereby the electric current that the loop consumes reduces the installation cost of manufacture of secondary control loop. Especially suitable Closing the flow-control of compressed natural gas electric control flow regulation decompressor uses.
Claims (2)
1, equivalent pressure cavity Electromagnetic Dynamic flow regulating and controlling valve, by electromagnetic coil (1), place the yoke in the electromagnetic coil (1), be provided with on the yoke axis elongation line and constitute spring return spool mechanism and the valve seat composition that opens and closes with yoke, it is characterized in that, adopt scyewed joint between the inwall of described yoke (2) and electromagnetic coil (1), the termination of yoke is equipped with and changes the edge of a knife (3), is provided with O RunddichtringO (4) between yoke and electromagnetic coil.
