The model utility content
Purpose of design: avoid the deficiency in the background technique, design a kind of can either be with gas electromagnetic valve instantaneous trip air feed, leading type electromagnetism gas emergency cut-off valve that again can manually opened air feed once more drives and the locking switch device.
Design proposal: in order to realize above-mentioned purpose of design.1, the design of manual clutch between dead electricity sucker electromagnet and the iron pan is one of technical characteristics of the utility model.The purpose of doing like this is: because the valve body secure fit of valve upper cover valve port top; Valve rod passes guide sleeve and valve upper cover mesopore; Its valve rod lower end is connected with the flap seal disc, the upper end is connected with dead electricity sucker electromagnet lower end; And be with main spring on the valve rod between valve upper cover and the flap seal disc, therefore when handle moved and be adsorbed on the iron pan through the T prefix on the little axle drive dead electricity sucker electromagnet, valve rod drives the flap seal disc to be separated with valve port; The main spring that is enclosed within this moment on the valve rod is compressed by the flap seal disc, has realized the order of manual separation; When the valve of manual pass, as long as push handle downwards, handle promotes dead electricity sucker electromagnet to be separated simultaneously with iron pan by force, and this moment, valve rod moved down under the effect of main spring, and flap seal disc and valve port are sealed and matched automatically, realize manually closing the valve purpose; 2, the design of demagnetization automatic closing, be the utility model technical characteristics two.The purpose of doing like this is: since dead electricity sucker electromagnet on structural design, have electric moment erasing characteristics; Therefore get when electric when dead electricity sucker electromagnet; The magnetic force pop-off of its dead electricity sucker electromagnet, obtained discharging by the elastic force of the main spring of flap seal disc compression this moment, and main spring promotes the flap seal disc and moves down; The flap seal disc is cooperated with sealing valve port, thereby realize demagnetization pass valve purpose.
Technological scheme: a kind of leading type electromagnetism gas emergency cut-off valve drives and the locking switch device; Valve port is provided with the flap seal disc; Valve upper cover is positioned at the valve port top and is fixedly connected with valve body; Valve rod passes guide sleeve and valve upper cover mesopore, and its valve rod lower end is connected with the flap seal disc, the valve rod upper end is connected with dead electricity sucker electromagnet lower end, and dead electricity sucker electromagnet upper end is connected with the little axle of T prefix; The T prefix that is with the little axle of handle and handle, at its lower end and T prefix on the little axle of T prefix is snap fit; Shell is enclosed within around the actuator that is made up of the little axle of guide sleeve, valve rod, iron pan, T prefix, handle and dead electricity sucker electromagnet and the shell lower end is connected with valve upper cover, be provided with lid on the shell, and iron pan is fixed and encircled in the enclosure on the boss, and main spring is enclosed within on the valve rod and between valve upper cover and flap seal disc.
The utility model is compared with background technique, and the one, simple in structure, reliable performance is convenient to manually open valve, is closed valve; The 2nd, dead electricity sucker electromagnet gets the design of electric demagnetization, has realized under the state of emergency, gets the order of electric demagnetization, automatic closing.
