Description
Technical field:
The utility model relates to a kind of fuel safety protecting valve, relates in particular to a kind of unexpected booster gas leakage unidirectional or two-way a kind of pipeline gas safety protective valve of closing combustion gas automatically that has.
Background technique:
At present, fuel safety protecting valve kind is numerous and diverse, and representative has three kinds approximately; First kind is super flow gas leakage automatic close-type fuel safety protecting valve, its shortcoming is: it only can satisfy in high pressure or middle compression ignite gas and uses, if use in the pipeline low-pressure fuel gas, when accidental gas leakage occurring, it fails effective automatic self-closing gas, performs practically no function; Other is that its enable switch is installed in the high-pressure gas zone, also occurs wearing and tearing gas leakage easily.Second kind is the automatic reverse close type fuel safety protecting valve of gas leakage that utilizes the control of permanent magnetism power, its shortcoming is: it only can guarantee to use in the setting pressure scope, if suction pressure is during greater than the working pressure scope that sets, it promptly automatically breakdown gas leakage cause bigger danger; The third is automatically controlled warning class fuel safety protecting valve, and its shortcoming is: need electric energy to be used as power, the electricity wasting energy simultaneously, also needs artificial regularly maintenance, if electronic alarm promptly can be malfunctioning by kitchen fume pollution, performs practically no function too, does not have use value.
Summary of the invention:
A kind of pipeline gas safety protective valve that the utility model provides, it is self pressure that utilizes gas, make pressure regulation lever or the automatic control of pressure regulation rubbish bar forward close fuel gas valve core, with the reverse fuel gas valve core of closing, in vain moving unidirectional or two-way effect of closing combustion gas when booster gas leakage occurring to reach gas pipeline; Not only can in the high, medium and low voltage combustion gas, use and guarantee safety, and not need to use controlling electric energy and manual maintenance.
According to above-mentioned purpose, a kind of pipeline gas safety protective valve that the utility model provides, it comprises valve chest, valve chest has the air inlet pathway that is interconnected and the pathway of giving vent to anger; Valve chest is divided into upper shell and lower shell body again, installing pressure-bearing elastomer diaphragm between upper shell and lower shell body, and at the center position of pressure-bearing elastomer diaphragm, the wooden fork pull bar is taken off in the installing pressure regulation; Between upper shell and pressure-bearing elastomer diaphragm, install pressure spring; The pressure regulation lever is installed on the lever strong point, and an end inserts pressure regulation and takes off in the wooden fork pull bar, and the other end extends reverse pressure regulation mouth and aligns the place, and installs a little plug of pressure regulation and match, to reach the effect of automatic adjusting air pressure; Its main feature is: in the appropriate position of air inlet pathway, install one and close forward closing the elastic force spool and forward closing valve seat and match of combustion gas along gas flow direction; Spool push rod of insertion interconnects or heads on mutually between the little plug of elastic force spool and pressure regulation forward closing, make the pressure regulation lever spool push rod of ining succession back down and forward close the elastic force spool by combustion gas self pressure, normal ventilation is used and the pipeline rear occurs forward closing combustion gas automatically when unexpected booster leaks gas to reach, and prevents that combustion gas is toward the effect of external leakage in the pipeline of the place ahead; Center position below lower shell body is taken off wooden fork pull bar bottom by automatically reset formula enable switch and pressure regulation in installing one and is headed on mutually, with in reaching by the normal effect of using of breakdown combustion gas; Center position above upper shell is installed a gas manometer scale, at the center position of gas manometer scale, offers the cone shape push rod that a push rod dragging track and pressure regulation take off wooden fork pull bar upper end and aligns; Offer a pointer running shaft through hole in a side of gas manometer scale, the pointer running shaft is inserted in the pointer running shaft through hole, an end passes barometric off-balancesheet portion, and connects pointer; The other end passes upper shell inside, and connects the cone shape push rod tangential that wooden fork pull bar top is taken off in an inclined-plane swivel plate and pressure regulation, to reach the effect that utilizes air pressure control gas manometer scale indicating gage rotation metering; Be inserted in the little spring that resets in pointer running shaft lower end, to reach the effect that the back pointer self-return of stopping the supple of gas or steam makes zero.
This pipeline gas safety protective valve also comprises a kind of two-way close type pipeline gas safety protective valve; Described two-way close type pipeline gas safety protective valve, it comprises valve chest, valve chest has the air inlet pathway that is interconnected and the pathway of giving vent to anger; Valve chest is divided into upper shell and lower shell body again; Installing pressure-bearing elastomer diaphragm between upper shell and lower shell body; Between upper shell and pressure-bearing elastomer diaphragm, install pressure spring; Its main feature is: at the center position of pressure-bearing elastomer diaphragm, install the pressure regulation pull bar that a lower end has cone; Elastic force pressure regulation push rod is inserted in the push rod pilot hole, the cone of one end and pressure regulation pull bar lower end is tangent, the other end stretches out forward closes appropriate position, valve seat outer end, and install one and forward close the elastic force spool or forward close the ball spool and head on mutually, by combustion gas self pressure, the pressure regulation push rod is directly backed down forward close the elastic force spool or forward close the ball spool, when leaking gas with the unexpected booster of appearance, forward close the effect that combustion gas prevents the past external leakage of combustion gas in the pipeline of the place ahead automatically to reach the normal ventilation use; In the appropriate position of giving vent to anger pathway, install a reverse ball spool of closing and match with the reverse valve seat of closing, to reach when accidental gas leakage appears in this valve the place ahead pipeline the reverse automatically combustion gas of closing, prevent in the pipeline of rear that combustion gas is toward to the effect of leaking; In the reverse appropriate position, ball spool rear of closing, install a clamp and the reverse ball spool of closing sticks mutually, to reach the reverse ball spool normal effect of using of influence of disorderly walking about of closing that prevents; Center position above upper shell is also installed one and is drawn the formula enable switch that automatically resets to be connected with pressure regulation pull bar top outward, to reach the effect that makes things convenient for the breakdown combustion gas to use.
Beneficial effect:
The beneficial effects of the utility model are: use in the high, medium and low voltage combustion gas, all can guarantee maximum safety, and do not need manual maintenance, energy saving.
