Abstract

The utility model relates to a self-holding electric valve driven by a motor, whichcomprises a valve body, a valve cap, a support frame and an operating mechanism. The operating mechanism comprises a motor, a driving wheel, a driven wheel, a connecting shaft, a connecting rod, a valve core, a valve seal, a spring, an armature and a magnet. The motor is fixed on the support frame, is driven by a pulsed voltage, and is provided with the driving wheel. The driven wheel, which meshes with the motor, is arranged on the support frame, and the connecting shaft is arranged on the driven wheel. One end of the connecting shaft is sheathed with the armature and the other end is hinged with the connecting rod. The other end of the connecting rod is hinged with the valve core which is sheathed with a guide sleeve, and the other end of the valve core is provided with the valve seal. The magnet is arranged on the support frame, and the spring is arranged between the valve seal and the support frame. The utility model has the advantages of small power consumption, simple structure, low cost and reliable performance, and is widely used for pipeline transportation control elements which take gas, liquid, etc. as working medium.

Description

Motor driving self-sustaining mortor operated valve

The utility model belongs to mortor operated valve, and what be specifically related to is that a kind of energy is realized self-sustaining motor driving self-sustaining mortor operated valve.

Controllable valve at present commonly used mainly contains following two kinds: 1. general solenoid valve, be divided into the AC and DC solenoid valve again, it has two kinds of open type and normal close types, desire to make its transition status, need continuous energising just can keep, therefore, the power consumption height, coil easily heating burns out, but especially is not suitable for being used to contain the occasion of explosive gas; 2. mechanical retaining electromagnetic valve, this valve adopts the folding condition of mechanical structure maintaining valve, but its complex structure, the cost height.

The purpose of this utility model is to overcome the shortcoming of the above prior art, provides a kind of power consumption mortor operated valve little, easy to manufacture.

The purpose of this utility model is achieved in that the utility model comprises valve body, valve gap, support and actuator, actuator comprises motor, driving wheel, follower, coupling shaft, connecting rod, spool, jam pot cover, spring, armature and magnet, motor is fixed on the support, the employing pulsed voltage drives, driving wheel is housed on the motor, the follower that is engaged with is installed on the support by gear shaft, coupling shaft is installed on the follower, armature is housed on it, one end and rod hinge connection, the other end of connecting rod and spool one end are hinged, and spool socket-connects with the guide pin bushing that is fixed in support, and the other end of spool is equipped with jam pot cover; Magnet is rack-mount; Spring is installed between jam pot cover and the support.Working principle of the present utility model is such: pulsed voltage drive motor forward or reverse, the drivening rod to-and-fro motion, simultaneously armature is with the magnet adhesive or separate, thereby makes the jam pot cover closure or openness and realize the self-sustaining purpose of outage under the acting in conjunction of power such as spring force.

Advantage of the present utility model is: the utility model adopts pulsed drive, realize the outage self-sustaining by magnet and spring etc., the static reactive consumption, dynamic current is little, so have that power consumption is little, simple in structure, an advantage of low cost of manufacture, reliable performance, can be widely used in the line transportation control unit that working medium is gas, liquid etc. for a kind of.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model embodiment's a structural representation.

Fig. 2 is the utility model embodiment's transmission principle figure.

As depicted in figs. 1 and 2, the utility model embodiment has a valve body 1, valve body 1 includes medium import 16, valve opening 18 between outlet 17 and the import and export, on valve body 1, be fixed with valve gap 10, support 9 is tightly connected between valve gap 10 and valve opening 18 and with valve body 1, on support 9, be fixed with motor 12, motor 12 adopts pulsed voltage to drive, driving wheel 4 is housed on the motor 12, follower 6 and driving wheel 4 engagements, follower 6 is installed on the support 9 by gear shaft 11, coupling shaft 5 is installed on the follower 6, and the one end is equipped with the armature 7 that soft magnetic material is made, and the other end and connecting rod 3 are hinged, the other end of connecting rod 3 and spool 2 one ends are hinged, spool 2 socket-connects with the guide pin bushing 13 that is fixed in support 9, and spool 2 can slide up and down in guide pin bushing 13, and the other end of spool 2 is equipped with jam pot cover 15, be positioned at valve opening 18, jam pot cover 15 is made of sealing skeleton and sealing gasket; Magnet 8 is installed on the support 9, can with armature 7 adhesives; Spring 14 is installed between jam pot cover 15 and the support 9, and when jam pot cover 15 was opened, spring 14 was compressed, and when jam pot cover 15 was closed, spring 14 diastoles made jam pot cover 15 seal the outlet of valve opening 18.

The motor 12 that pulsed voltage drives drives follower 6 forward or reverse, 3 to-and-fro motion of follower 6 drivening rods, and connecting rod 3 drive spools 2 move up and down, when a pulse makes connecting rod 3 motions stop to the top position, armature 7 and magnet 8 adhesives, make spool 2 jam pot covers 15 remain on opening state, when another pulse moves downward connecting rod 3, armature 7 separates with magnet 8, when connecting rod 3 stops to lower position, make jam pot cover 15 remain on closed state by the deadweight of jam pot cover 15 and the elastic force of spring 14 etc., thereby reach the purpose of blocking-up or connection pipeline medium.
