Abstract
The utility model relates to a domestic energy-saving combustion gas valve. A valve body is connected with a valve cover in buckling mode to form the valve cavity of the valve. Atapered air inlet nozzle is arranged on the valve body, and the periphery of an air inlet is provided with a permanent magnet. An elastic resetting button rod is arranged on the valve cover and inserted into the valve cavity. The lower end of the button rod is arranged in coaxial mode with an armature iron, a rubber closing plate and a corrugation rubber diaphragm. An adjusting rod of which the lower end is provided with a voltage stabilization ball is arranged under the button rod, and the lower part of the adjusting rod extends into the air inlet nozzle. After a duct stops feeding gas, the self-closing valve can automatically close a gas circuit and can carry out voltage stabilization output after gas pressure exceeds standard. Simultaneously, the utility model also has the actions of saving the gas and purifying the waste gas.
Description
The utility model belongs to the pipeline valve field, relates to a kind of energy-conservation valve that can carry out voltage stabilizing and close gas circuit automatically after stopping the supple of gas or steam the home pipeline combustion gas.
In the daily life, when the family expenses gas pipeline did not temporarily have gas, people were usually owing to throttle down is forgotten in carelessness, like this after pipeline recovers air feed, combustion gas is just released very soon and is filled the air in indoor, has both caused the source of the gas waste, also easily causes personnel's gas poisoning or leads to fire accident; In addition; it is outdoor to remove using of city specialty coal gas or the supply of natural gas company at present in using the life user of home pipeline combustion gas; the a considerable amount of users that utilize industry production or speed to put back to inflammable gas lives such as getter are still arranged; these units since in being produced the influence of various factors have often that pipeline gas pressure exceeds standard and the phenomenon of stopping the supple of gas or steam occurs; these all bring danger to the user, and the user has carelessness to have an accident slightly.
The purpose of this utility model is according to the existing in prior technology problem, design the simple and practical home pipeline combustion gas voltage stabilizing self closing stop valve of a kind of structural principle, this self closing stop valve can cut out gas circuit automatically and can carry out voltage stabilizing after gaseous-pressure exceeds standard after gas pipeline is stopped the supple of gas or steam, it also has the effect of saving combustion gas and purifying exhaust air simultaneously.
For achieving the above object and the design the home pipeline gas self-closing valve have a hollow valve pocket that connects and composes by valve body and valve gap make-up, valve body is used for being connected in series with gas pipeline, have center suction port and sidewall air outlet on it, the top of its center suction port has a conical nozzle, periphery at suction port is arranged with at least two permanent magnets, valve gap is provided with an elastic reset button bar that inserts valve pocket, the coaxial armature that is provided with in the lower end of restoration button bar, rubber shrouding and corrugated rubber film, utilize the corrugated rubber film can be with valve pocket every being divided into valve chamber and lower valve chamber, also coaxially under restoration button bar be inserted with the adjustable lever that a lower end has the voltage stabilizing ball, the top of this adjustable lever is located in the end mandrel vestibule of restoration button bar through the rubber shrouding, and the bottom is stretched in the conical nozzle of suction port.This valve in the course of the work, the action of restoration button bar is by following four kinds of active forces decision: i.e. the pressure of inflow gas in the elastic force of the magnetic force of the gravity of the body of rod and body of rod accessory, permanent magnet, button bar spring and the lower valve chamber.Armature in four equilibrium of forces under the normal air feed situation, valve pocket leaves permanent magnet, and gas enters from suction port, again through conical nozzle and air outlet to the kitchen range air feed.When suction port pressure was lower than authorized pressure or stops the supple of gas or steam, owing to be subjected to gravity, the restoring force of button bar spring and the magnetic force of magnet, armature was held by magnet, and the rubber shrouding is sealed suction port simultaneously, thereby the realization fuel gas pipeline is closed automatically.When suction port pressure surpasses specified value, the power that acts on the corrugated rubber film increases, make it to move up, drive adjustable lever and voltage stabilizing ball simultaneously and rise, because spout is a tapered channel, so along with the rising of voltage stabilizing ball, gas channel reduces gradually, valve pocket lower valve chamber internal pressure descends thereupon, and the delivery pressure of gas is maintained on the force value of regulation use, realizes pressure stabilization function.In addition, at gas flow in the process of valve pocket lower valve chamber because the high magnetic fields of permanent magnet makes the gas magnetization, from and reached the effect of saving combustion gas and purifying combustion waste gas.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the cross-sectional view of a specific embodiment of the utility model.
As shown in the figure, the valve body 8 that has center suction port 4 and sidewall air outlet 1 on it is one to be connected on the shelly object on the gas piping, and it and a spill valve gap 14 fasten the valve pockets that constitute self closing stop valves mutually.Elastic reset button bar 12 is the manually operated type valve rod that has spring 11 on the wall bar, and it inserts valve pocket outside to inside from valve gap, is provided with a mandrel hole, the end that adjustable lever 13 is moved up and down in the bottom of button bar 12.Rubber capping 6, armature 7 and corrugated rubber plate 9 are located at the lower end of restoration button bar 12 respectively, and wherein corrugated rubber plate 9 can be with valve pocket every being divided into valve chamber II and the I of lower valve chamber.Suction port 4 is the port that a top has conical nozzle 3.Two symmetrical respectively peripheries that are located at suction port 4 of permanent magnet 2 also can only be established an inner loop shape permanent magnet in suction port 4 peripheries when specifically implementing.Adjustable lever 13 can move up and down in valve body suction port 4 chambeies, the top of this bar is passed rubber shrouding 6 and then is inserted in the axis hole chamber, bottom of restoration button bar 12, the bottom is then stretched in the conical nozzle 3 of suction port, in the lower end of adjustable lever 13 voltage stabilizing ball 5 is housed, suitably adjust the length of adjustable lever 13 and the elastic force of spring 11 during design is used, can guarantee that the pressure of valve pocket inlet gas is output as certain value.Number in the figure 10 is the valve gap spiracle.
The suction port of valve body described in the utility model also can mentioning or press by the people to opening or closing by the button bar.
