Abstract

The utility model provides a timed self-closing gas valve. The timed self-closing gas valve comprises a shell body, a bushing, a valve rod, a valve core, a timing device and a spring. The timed self-closing gas valve is characterized in that the opening time of the timed self-closing gas valve can be set in a specified time of the timing device according to individual needs; when the set time comes, the timed self-closing gas valve is closed automatically at an instant, gas is cut off, fire goes out, and any disastrous effect caused by the situation that people forget to switch off a stove when the people use the gas to boil water and cook is avoided.

Description

Combustion gas timing automatic closing valve door

Technical field

The utility model relates to a kind of control valve unit, particularly relates to a kind of valve of can timing automatic closing.

Background technique

Employed valve on the present family gas pipeline, the ball valves that adopt more, this valve can only be artificially open and close, but in the actual life, some family has formed the custom of valve on the blanked-off pipe road not, this phenomenon uses combustion gas to bring many hidden dangers to people, the ZL0324043.4 China utility model patent of granting patent on May 12nd, 2004, a kind of combustion gas timing automatic closing valve door is disclosed, it comprises: housing, valve rod, spool, shutoff, sealed sliding is stifled, valve gap, timer, spring, knob and valve rod are installed passage, though this valve can address the above problem, but owing to adopt sealed sliding stifled, cause valve in the moment of closing, the gas leakage of trace is arranged.

Summary of the invention

The purpose of this utility model provides a kind of opening time that can will set valve according to the individual, reaches set time, and valve moment closes automatically, stops gas leakage, combustion gas timing automatic closing valve door simple in structure.

The purpose of this utility model be by provide a kind of have as the combustion gas timing automatic closing valve door of lower device realize, it is by housing, mend core, valve rod, spool, seal ring, pad, spring, timer, valve gap, knob, backing pin, outlet nozzle and time indicator panel are formed, described benefit core stationary fit embeds to form in the housing has the gas-entered passageway that is interconnected, outlet passageway and valve rod are installed the valve body of passage, described valve rod is installed in valve rod movingly and installs in the passage, described spool adopts the embedded tapered sealing of spring, be threaded and be fixed on an end of valve rod upper valve body gas-entered passageway, described seal ring, pad, spring is installed on the valve rod of the corresponding end of spool, described timer is a mechanical timer, be installed in the valve body and contact with valve rod, described valve gap embeds and is fixed on timer one end on the valve body, described outlet nozzle is threaded and is fixed on the valve body outlet passageway, described knob is installed on the axostylus axostyle that timer passes the valve gap center hole, described gas-entered passageway, the outlet passageway shaft axis is vertical, move axially along valve body at the effect lower valve rod that manually reaches spring, by knob, timer, valve rod, spring, the moving system that spool is formed overlaps with the valve body shaft axis, described timer is a mechanical timer, not electricity consumption during use can be set valve closing time arbitrarily at timer in the stipulated time.

The utility model is compared with existing combustion gas timing automatic closing valve gate technique has following characteristics: housing, the benefit core of forming valve body are the forging and pressing once-through, reduced the operation of machining, throttle down adopts the embedded tapered sealing of spring, stopped valve close moment gas leakage problem.

Description of drawings

This figure is the sectional view that this combustion gas timing automatic closing valve door is in opening state.

Among the figure, 1, housing; 2, mend core; 3, valve rod; 4, spool; 5, seal ring; 6, pad; 7, spring; 8, timer; 9, valve gap; 10, knob; 11, backing pin; 12, outlet nozzle; 13, gas-entered passageway; 14, outlet passageway; 15, valve rod is installed passage; 16, time indicator panel.

Embodiment

Mode of execution of the present utility model is described with reference to the accompanying drawings:

This combustion gas timing automatic closing valve door is by housing 1, mend core 2, embedded stationary fit is formed and is had the valve body that gas-entered passageway 13 outlet passageways 14 that are interconnected and valve rod are installed passage 15, valve gap 9 embeds and is fixed on timer 8 one ends on the valve body, outlet nozzle 12 is threaded and is installed on the outlet passageway 14, time indicator panel 16 is fixed on the outside of valve gap 9, timer 8 is installed in the valve body, valve rod 3 is installed on valve rod and installs in the passage 15 to become movingly, spool 4 is threaded and is installed in gas-entered passageway 13 1 ends on the valve rod 3, seal ring 5, pad 6 places on the valve rod 3 by the tension force of spring and is fixed on the benefit core 2 with spool 4 corresponding ends, push-turn key 10 and go to time of required setting clockwise vertically during Open valve, backing pin 11 is stopped by valve gap 9 internal surfaces on timer 8 axostylus axostyles at this moment, gas-entered passageway 13 outlet passageways 14 are communicated with, and spring 7 is in compressive state, when valve opening time reaches set time is that backing pin 11 transfers back to valve gap 9 center hole indentation, there counterclockwise on timer 8 axostylus axostyles, being compressed spring restores, knob 10, timer 8, valve rod 3, spool 4 axially moves under the effect of spring 7 tension force and resets, cut off gas-entered passageway 13, the connection of outlet passageway 14, the purpose of realization moment automatic-closing valve.
