Abstract
The utility model relates to a flip-flop electric magnet for a valve, characterized in that a hole at one head of the draw rod (4) of a shackle is provided with a small spring (5), a lock core (6) and steel balls (7, 8); the hole of a lock sleeve (9) is provided with a circular step; the push rod (17) of the shackle and a movable iron core (16) are supported by a spring (19); automatic electricity cutting is accomplished in a way that a disc (1) sheathed with one end of the draw rod drives a small lever (13) to poke microswitches (10, 14). The utility model has the advantages of nondirectional installation, convenient installation and maintenance, energy and material saving and safety and is suitable for controlling all the two-position valves in the hydroelectric and electromechanical industries.
Description
The utility model belongs to electromagnetic valve.
At present, domestic is that the supporting bistable state of valve is cut off the power supply electromagnet seldom certainly, and having then is the monostable Electromagnetic Control, though the also promising requirement of satisfying the water power plant, and produce bistable electro-magnet, be the big heaviness of body, belong to vertical structure, installation has directivity, expends deficiencys such as the energy and material.
The purpose of this utility model provides a kind of light economize on electricity, and direction-free bistable electro-magnet is installed, and uses to draw as valve.
Structure of the present utility model such as accompanying drawing.Accompanying drawing is a valve with bistable electromagnetic iron construction cut-away view, wherein 1, shell; 2, snap close coil; 3, moving iron core; 4, pull bar; 5, little spring; 6, lock core; 7,8, steel ball; 9, lock tube; 10,14, sensitive switch; 11, disk; 12, rotating shaft; 13, small lever; 15, trip coil; 16, moving iron core; 17, push rod; 18, shell; 19, spring.
Characteristics of the present utility model are in the hole of (4) one on pull bar of snap close little spring (5), lock core (6), steel ball (7,8) to be housed, have two apertures on the hole wall, allow steel ball (7,8) pass in and out, in the hole of lock tube (9) step cutting pattern is arranged, to block steel ball, interference fit between the lock tube lower yoke therewith; Push rod (17) of threading off and moving iron core (16) are supported by spring (19), make installation non-directional; The small lever (13) of going into disk by disk that is enclosed within pull bar (4) one ends (11) and fork from outage is connected with sensitive switch (10,14).
The lock core of bistable electro-magnet (6) is a dumbbell-like shape, and its groove is 1/3rd of diameter of the steel ball deeply; The hole wall of pull bar (4) is thick to be 2/3rds of diameter of the steel ball, and steel ball is stuck in groove and the hole wall aperture just.
Big bore dia deducts pull bar (4) hole wall external diameter to equal 2 times the groove of lock core (6) dark in the lock tube (9), and steel ball is stuck in lock tube and the hole wall aperture just.
Have a circular hole on the disk (11), so that small lever (13) swing.
One end of small lever (13) has a rectangular aperture, so that fork is gone into disk (11).
Below in conjunction with accompanying drawing embodiment is further specified:
The utility model is the specific (special) requirements at solenoid valve product in the Hydropower Plant automatic control system, adopts bistable state, the electromagnet of outage type certainly of miniaturization, the mechanical type snap close; Adopting small lever directly to stir sensitive switch from outage realizes, an end that is small lever (13) has rectangular aperture, fork is gone into the edge of disk (11), the other end of small lever (13) is a semi-circular shape, both sides prop up the button of sensitive switch (10) and (14), there is an aperture at the middle part of small lever, plug-in mounting rotating shaft (12), and the rotating shaft two end supports is in the rotary shaft hole of shell (1); Trip coil is contained in the shell (18), after pack in the shell (1).Working power can directly adopt high voltage direct current 220V power supply.
When solenoid valve need commutate, snap close coil (2), moving iron core (3) pushing drawing rod (4) also is being with little spring (5), lock core (6), steel ball (7,8) move right together, when the vertical center line of steel ball arrives or surpass in lock tube (9) hole step, steel ball is extruded it owing to little spring (5) promotes lock core (6), and be stuck in step place in lock tube (9) hole, pull bar (4) can not be returned, steel ball (7,8) diameter equals pull bar (4) hole wall, and thick to add upper lock core (6) intermediate groove dark, when pull bar (4) moves right, driving disk (11) moves right together, and stir small lever (13) by the edge of the aperture on the disk (11), and sensitive switch (10) contact is disconnected, working power is cut off automatically, and sensitive switch (14) junction closure makes trip coil (15) prepare to such an extent that electric realization is threaded off.When that is to say valve work, electromagnet is cold, and so both power savings have increased functional reliability again.
When work finishes, when spool need reset, trip coil (15), moving iron core (16) drives push rod (17) promotion lock core (6) and is moved to the left, compress little spring (5) simultaneously, when recess moves to the vertical center line of steel ball in the middle of the lock core (6), steel ball is acted on the counter-force on the step inclined-plane in lock tube (9) hole by valve spring force left and squeezes in the groove at the hole wall of getting back to pull bar (4) and lock core (6) middle part, by the spring force of valve pull bar is retracted and to reset, snap close is taken off, pull bar (4) drives disk (11) simultaneously, stir small lever (13) by the little bore edges on the disk, make sensitive switch (14) cut off working power automatically, sensitive switch (10) contact is connected simultaneously, prepares task under the snap close coil.
When snap close is thrown off, after pull bar (4) resets, trip coil (15) is outage automatically, spring force by spring (19) makes the weight of iron core (16) and push rod (17) be supported by spring (19), electromagnet also can be worked when vertical placement, make the utility model realize installing direction-free requirement like this.
Electromagnet is connected with solenoid valve by big lever, with control electromagnetic valve work; Also can electromagnet be connected direct pull spool, the work of control valve by transition plate with valve body.
Effect of the present utility model is to have solved for a long time magnetic valve worker in the Hydropower Plant automatic control system The specific (special) requirements of doing makes bistable electromagnetic valve miniaturization in the Hydropower Unit automatic control system, Reliability Enhancement . It is non-directional to have installation, saves the energy and material, advantage convenient for installation and maintenance.
The utility model is applicable to the bistable state of valve element in water power, the automatic control system of electromechanical industries, electricity The Self-disconnecting function of magnet is applicable to the control of all two-position valves.
