Abstract
The utility model relates to a self protective electromagnetic valve which has small electric consumption, can save energy and can conveniently control. The utility model is composed of a shell body, a skeleton and a coil which are arranged in the shell body, and a piston casing tube and a piston which are arranged in the skeleton, wherein a permanent magnet which is arranged in the shell body and cooperates with an electromagnet which is composed of the coil and the shell body.
Description
The utility model relates to a kind of self-insurance's solenoid valve with self protective function.
Existing solenoid valve by housing, be placed on skeleton and coil in the housing, be contained in intraskeletal piston sleeve and inner Returnning spring be housed, the lower end is made up of the piston of push rod.During actual the connection, the solenoid valve lead-in wire connects power supply by control switch, and piston sleeve links to each other with the pipeline main control valve by flange.When solenoid valve gets when electric, be in opening state; Otherwise, then be in closed condition.Because in working control, the most of the time all will be connected main line, and therefore, solenoid valve is corresponding also will work connecing under the electricity condition.Like this, just make that the solenoid valve power consumption is big, particularly large-scale solenoid valve, power consumption is very big, makes the production run cost increase.
The purpose of this utility model is to provide a kind of power consumption little, energy-conservation and control self-insurance's solenoid valve easily.
The utility model be achieved in that it by housing, be placed on skeleton and coil in the housing, be contained in intraskeletal piston sleeve and piston is formed, it also is placed with the permanent magnet that is complementary with the electromagnet that is made of coil and housing in housing.
Because this solenoid valve is in off-position under the opening and closing state, promptly keep opening state and be magnetic force by permanent magnet, and the switching that opens and closes by forward and reverse push-button switch by moment forward and reverse electricity that connects realize, therefore, this solenoid valve has self protective function, and control is convenient, and particularly power consumption is minimum, has reduced energy consumption widely.
The drawing explanation:
Fig. 1 is a structural representation of the present utility model;
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in the figure, the utility model has a housing 1, in housing 1, be placed with permanent magnet 2, on permanent magnet 2, be placed with skeleton 3, on skeleton 3, be wound with coil 4, the magnetic flux of said permanent magnet 2 is complementary with the magnetic flux of the electromagnet that is made of coil 4 and housing 1, be stamped gland 9 in skeleton 3 upper-end surfaces, locating sleeve 10 is equipped with in mesopore bottom at skeleton 3, being fitted with the top in the mesopore of skeleton 3 is flange 6B, the piston sleeve 6 of end socket 6A is equipped with in the bottom, said end socket 6A is fastening by the screw 11 that passes housing 1 bottom surface, and be placed with between flange 6B and the gland 9 and adjust spring 8, piston 7 is housed in piston sleeve 6, Returnning spring 7B is housed in the said piston 7 and draws push rod 7A, draw the terminal 5 of this solenoid valve at the two ends of coil 4.
When physical cabling, this solenoid valve links to each other terminal 5 connection control circuits by flange 6B with main control valve on being installed in main line.When 4 forward moments of coil get electric (excitation direction is identical with permanent magnet 2), the magnetic of coil 4 and permanent magnet 2 makes a concerted effort to make piston 7 to move down, and during near permanent magnet 2, the magnetic pull of 2 pairs of pistons 7 of permanent magnet increases; After coil 4 dead electricity, keep the attracting state of piston 7 by the magnetic force of permanent magnet 2, thereby make this solenoid valve be in opening state, realize opening the valve self-insurance.Otherwise, when 4 reverse moments of coil get electricly, because the excitation direction of coil 4 is opposite with the excitation direction of permanent magnet 2, magnetic force reduces greatly, under piston 7 effect of the Returnning spring 7B of portion within it, push rod 7A is stretched out, and then make piston 7 upwards bounce-back and returning position, this solenoid valve is turn-offed, because piston 7 becomes big with permanent magnet 2 distances, suction reduces, and piston 7 still keeps closed condition after coil 4 dead electricity, realizes closing the valve self-insurance.
