Description

A kind of energy-saving gas flameout protecting electromagnetic valve
Technical field
The utility model relates to a kind of energy-saving gas flameout protecting electromagnetic valve.
Background technology
Magnetic valve (Electromagnetic valve) is the industrial equipment by Electromagnetic Control, is for controlling the automation foundation element of fluid, belong to actuator, being not limited to hydraulic pressure, pneumatic.Be used in direction, flow, speed and other the parameter of in industrial control system, adjusting medium.Magnetic valve can coordinate different circuit to realize the control of expection, and precision and the flexibility controlled can both guarantee.Magnetic valve has a variety of, and different magnetic valves plays a role at the diverse location of control system, and the most frequently used is check valve, safety valve, directional control valve, speed-regulating valve etc.Magnetic valve is divided into three major types from principle: 1, direct-acting electromagnetic valve: principle: during energising, solenoid produces electromagnetic force mentions closure member from valve seat, valve open; During power-off, electromagnetic force disappears, and spring handle closure member is pressed on valve seat, valve closing.Feature: can normally work when vacuum, negative pressure, zero-pressure, but latus rectum is generally no more than 25mm.
2, step direct-acting type electromagnetic valve: principle: it is a kind of straight moving and principle that pilot-operated type combines, when entrance and outlet do not have pressure reduction, after energising, electromagnetic force is directly upwards mentioned the little valve of guide and main valve closure member successively, valve open.When entrance and outlet reach while starting pressure reduction, after energising, the little valve of electromagnetic force guide, main valve cavity of resorption pressure rise, upper cavity pressure declines, thereby utilizes pressure reduction that main valve is upwards pushed open; During power-off, pilot valve utilizes spring force or pressure medium to promote closure member, moves down, and makes valve closing.Feature: also can * action when zero pressure difference or vacuum, high pressure, but power is larger, requires level to install.
3, guide electromagnetic valve: principle: during energising, electromagnetic force is opened pilot hole, upper chamber's pressure declines rapidly, at closure member, forms low high pressure reduction around, and fluid pressure promotes closure member and moves up, valve open; During power-off, spring force cuts out pilot hole, and inlet pressure bends down high pressure reduction by the formation around closing valve member of the rapid chamber of by-pass prot, and fluid pressure promotes closure member and moves down, valve-off.Feature: fluid pressure range limit is higher, can install arbitrarily (needing customization) but must meet fluid pressure difference condition.Magnetic valve is also usually for daily life, such as; The magnetic valve of installing in gas-cooker has just played the effect of switch.But the magnetic valve sensitivity in gas-cooker is still needed and is further improved at present, and in use, after gas extinguishing fire, magnetic valve needs certain hour (approximately 3 seconds) valve could be closed completely.Thereby after the long-term use of gas-cooker, there is certain potential safety hazard.
Summary of the invention
For above-mentioned technological deficiency, the utility model proposes a kind of energy-saving gas flameout protecting electromagnetic valve.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of energy-saving gas flameout protecting electromagnetic valve, be included in the valve seat 5 that upper end is set with valve bonnet 10, the lower end cover of described valve seat 5 has flange 4, in flange lower end, be arranged with fairlead 1, in fairlead 1, be provided with the electrode 2 of connecting valve seat 5, in valve bonnet 10, be provided with the static iron core 11 that is connected in valve seat 5, static iron core 11 overcoats have skeleton 8, on skeleton 8, be wound around coil 9, in valve bonnet 10, be also provided with the moving iron core 12 that is connected to valve shaft 14 one end, the other end of valve shaft 14 connects a sealing gasket 16, sealing gasket 16 is positioned at outside valve bonnet 10, between sealing gasket 16 and valve bonnet 10 ends, be provided with a spring 13, spring 13 is enclosed within outside valve shaft 14.
Further, described valve bonnet 10 and described valve seat 5 snappings.
Further, between described valve seat 5 and electrode 2, electrode sealing ring 3 is set
Further, at the top of described spring 13, spring base 16 is set.
Further, described skeleton 8 is fixed on skeleton binding post 7, and described skeleton binding post 7 is fixed in valve seat 5, and described skeleton binding post 7 lower ends are through valve seat 5, flange 4.
The beneficial effects of the utility model are: the magnetic valve of the gas furnace of the utility model design, guarantee gas furnace can moment open and close valve, and when accident extinguishing or reach after the burning time of setting, valve-closing blocking-up fuel gas path, prevents that combustion gas from escaping rapidly; Combustion process is protected and automatically controlled, realize the flame-out safeguard protection of gas furnace.
