Abstract
The utility model discloses a motor magnet-absorbing opened, spring-relieving closed gas safety valve, comprising a mini-motor, a gear box, a thread transmission shaft, a valve end cover, a motor box, a valve body, an inlet hole and an outlet hole, wherein the mini-motor built in the motor box is connected with the thread transmission shaft sleeved with a master magnetic steel through the gear box, the motor box and the valve body are connected together through a system coupling, a sub-magnetic steel traveling guide way and a spring supporting plate are arranged in the valve body through a connecting bolt on the bottom of which sleeved with a U adapter with a sub-magnetic steel and a spring and on the bottom of the U adapter sleeved with the valve end cover. With the reasonable structure and good design, the utility model is completely isolated from valve motor and the gas, thereby blocking thoroughly the gas touching with the electric arc produced during the motor running to prevent from the burning and explosion possibly occurred, and ensuring the valves safety and reliable in use with good value for application.
Description
Technical field:
The utility model belongs to technical field of valve manufacturing, particularly relates to the Safety valve that occasions such as a kind of pipeline at flammable explosive gas, measure meter are used.
Background technique:
At present, the general gas valve of Shi Yonging because blast tube and motor case do not cut off, so the electrical spark that produces during machine operation once contact with flammable explosive gas, very easily burns, explosive accident, constitutes a serious threat to the people life property safety.Be subjected to the structural limitations of such valve simultaneously, it is shorter to open Valve travel, and the build-up of pressure loss ratio is bigger, again because such valve ending cover swing degree is bigger, so cause rate of fault higher.
Summary of the invention:
The purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, makes the motor valve of magnetic-suction-opening that valve driving machine and gas cuts off fully, the safety valves for gas of spring-relaxation-closing valve.
For achieving the above object, the technological scheme that the utility model adopted is, a kind of motor valve of magnetic-suction-opening, the safety valves for gas of spring-relaxation-closing valve, mainly be by micromachine, gear-box, screw-thread drive shaft, valve ending cover, the motor case, valve body, composition such as inlet hole and air outlet hole, its characteristics are: the micromachine that the motor case is built-in with links to each other with the screw-thread drive shaft that is with main magnet steel by gear-box, and the motor case links to each other by system's joiner with valve body, be provided with auxiliary magnetic steel displacement guide rail and spring-support plate by connecting bolt in the valve body, be provided with " U " type adapter that is equipped with secondary magnet steel and spring outside it, the bottom of " U " type adapter is with valve ending cover.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion, the utility model is rational in infrastructure, be skillfully constructed, because this valve has used one group of magnet steel that there is a natural attraction between the sexes, magnetic field space between the major and minor magnet steel forms the isolation zone, motor is enclosed in the motor case, because motor and gas cut off fully, the electrical spark that has produced when thoroughly having blocked machine operation contacts with gas, avoided the burning that may cause, explosion phenomenon, stopped potential safety hazard, guaranteed that valve uses Security and reliability in flammable explosive gas.It has also increased the displacement height of secondary magnet steel simultaneously, rational auxiliary magnetic steel displacement guide rail is set, stablized the movement locus of valve ending cover, thereby possessed than conventional motors valve sufficiently high valve open and close stroke has been arranged, can reduce pressure loss to greatest extent, flexibility is good, the advantage that the rate of fault of switch valve is low, tool promotional value.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Referring to accompanying drawing, be provided with DC micromotor 2 in the motor case 1 of this valve, be connected with the screw-thread drive shaft 6 that is with main magnet steel 5 by gear-box 3 and positioning plate 4, the corresponding position of motor case and main magnet steel be provided with main magnet steel on the main magnetic steel displacement guide rail 9 of groove coupling, the motor case cavity under the main magnet steel is a main magnetic steel displacement cavity 10.Motor case and valve body 20 are connected and fixed by clamping bolt 14 by system connector 12, and the bottom of system connector also offers nest hole 7.The valve body that offers valve inlet hole 18 and valve air outlet hole 19 is provided with auxiliary magnetic steel displacement guide rail 15 and elastic supporting plate 21 by the connecting bolt under the system connector 11, be provided with " U " type adapter 13 that is equipped with secondary magnet steel 8 and spring 16 outside it, the bottom of " U " type adapter 13 is with valve ending cover 17.Wherein, the face that major and minor magnet steel is relative is a different pole.In use, motor is connected power supply forces main magnet steel to open the valve motion, and magnetic force is inhaled moving secondary magnet steel, drives " U " type suspension member, makes the rubber valve end cap leave the end face of valve air outlet, opens valve events thereby finish valve; Motor reversal connection power supply under the effect of spring-relaxation power, is finished the pass valve events of valve, has realized the fundamental function of valve.
