Abstract
The invention relates to a power-on on-off mechanic holding magnetic valve, which comprises the following parts: valve body, diaphragm flap, bonnet, spool shaft, spool cover on the bonnet, still iron core and magnetic coil, wherein the up lock case and down lock case encased on the T-shape column spool shaft is set in the valve body; the outer lock case is fixed on the inner wall of spool shaft cover; the spool shaft mechanic holding structure is composed of spring structure locating on the T-shape column spool shaft and up still iron core and up lock case base. The valve can finish and keep spool shaft rising to open the valve continually when the valve processes on-off power supply instantaneously. The spool shaft can release the mechanic holding structure and drop diaphragm flap to close the valve after the valve processes on-off power supply again.
Description
Technical field
The present invention relates to the solenoid valve technical field.
Background technique
Existing solenoid valve generally is the monostable internally piloted valve, promptly opens automatically after energising or closes, but need continued power just can keep its unlatching or closing state.This just not too is applicable to and lacks the working environment of stablize mains supply or some low power consumptions, long-time use.Many for this reason people propose Technological improvement plan to above-mentioned solenoid valve, and purpose is to make valve behind moment energising unlatching or throttle down, promptly automatically locks unlatching or closes working state, and do not need electric power to keep.The method of Locked valve working state in each scheme all is to utilize spring force and magnetic force basically at present, promptly adopts spring and permanent magnet, or permanent magnet and electromagnet, or the locking framework of two groups of electromagnetic assemblies.Above structure needs very big pulse energy to supply with and switches electromagnet when carrying out the working state conversion, and structure is complicated, and volume is bigger, and still need consume certain electric power.
Summary of the invention
Purpose of the present invention provides a kind of not power consumption and can keep valve opening automatically or close the novel solenoid valve of the locking framework of working state, and requires this locking framework simple in structure, and volume is little, low cost of manufacture, and flexible movements are reliable.
The technical solution that realizes above-mentioned purpose is: it comprises valve body, the diaphragm type flap, valve gap, valve core rod, be connected in the spool case on the valve gap, static iron core and electromagnetic coil, wherein valve core rod is the T cylindrical rod, its lower beam portion is with lock tube and following lock tube, last lock tube lower end is respectively equipped with the helical teeth that cooperatively interacts with following lock tube upper end, fixedly connected with the bottom of following lock tube in the lower end of valve core rod, the lower end of following lock tube is connected with the center gland of diaphragm type flap, the lock tube outside is provided with the outer lock tube that is fixed in valve core rod encloser inner wall face up and down, outer lock tube internal face bottom is provided with the chute rail that matches with the uniform axial slide of lock tube outer circumferential face up and down, and chute rail upper end is provided with locking and puts the inclined-plane that helical teeth matches, and is separately installed with spring between the lock tube on the T spool valve core bar swollen protuberance in upper end and top static iron core and the below.
The invention has the beneficial effects as follows: valve is through the moment switching, promptly finish valve core rod and promote, make valve opening, then under the effect of the mechanical retaining means that lock tube, outer lock tube and spring are up and down formed, the lifting state of maintaining valve core bar, and reach the lasting unlatching of valve; Only after moment power on/off once more, just can make valve core rod break away from mechanical retaining means and decent is pressed the diaphragm type flap, make valve closing.Mechanical retaining means of the present invention is simple in structure, and volume is little, low cost of manufacture, and flexible movements are reliable, and use not power consumption.
