Abstract
The utility model relates to a time control valve for gas, which is a device which is arranged on an air inlet pipe of a gas cooker and capable for controlling the gas to be timed and closed. The utility model is provided with a valve body on which an air inlet and an air outlet are arranged, a valve core is arranged in the valve body, and the top of the valve core is contacted with a timer thimble. The utility model is characterized in that a bottom cover on the lower part of the valve body is tightly connected with the valve body, a spring is arranged between the bottom cover and a thickest section on the valve core, the center of the bottom cover is provided with a guiding hole, the lower end of the valve core is inserted into the guiding hole, and a flat washer is arranged between the valve body and the bottom cover. The utility model has the advantages of simple structure and reasonable structure. The gas cooker can be controlled to be timed and closed, safe and reliable use is ensured, and energy source is saved.
Description
The utility model relates to a kind of device that home-use gas cooker regularly can be closed, is a kind of Gas time-control device specifically.
Family is when using gas cooker to cook food, and the food that has needs the boiling of long period, in cooking process, may be because a variety of causes, people leave cooking stove, are easy to forget close stove fire, and the time has been grown, the burnt food of meeting, dryout, burn at the bottom of the colander, even more serious meeting generation pressure kettle blast, even cause fire, cause very big threat for people's life, property, and wasted the energy.
The utility model purpose is to solve the problems of the technologies described above, and proposes a kind of Gas time-control valve, is installed on the suction tude of gas cooker, and the needs according to people cook food preestablish the time, can close automatically then.
The utility model purpose is realized by following technological scheme: this Gas time-control valve, a valve body is arranged, an inlet hole and an air outlet hole are arranged on the valve body, spool is housed in valve body, and the spool top contacts with the timer thimble, it is characterized in that the bottom of valve body lower portion closely is connected with valve body, between the thickest one section spring is housed on bottom and the spool, there is a pilot hole at the bottom center, and insert in the pilot hole spool lower end, between valve body and the bottom plain washer is housed.
When people when the other operation of gas cooker cooks food, the Gas time-control valve is a normally open, timer also is in normally open, the thimble of timer is depressed spool downwards, the Gas time-control valve is opened, spool stretches out valve body 0--5 millimeter; When not using gas cooker, the Gas time-control valve is a normally off, and timer also is in normally off, and the thimble of timer moves back upwards, and spool is because the elastic force of spring makes progress and the valve body closure, and spool stretches out valve body 1--6 millimeter; When needs regularly cook food, timer to be dialled on the time of setting, the thimble of timer overcomes the elastic force of spring and the pressure of air inlet, depresses spool downwards, and this moment, the Gas time-control valve was opened.Arrived set time, the thimble of timer can move back upwards automatically, because the pressure of spring, above spool pressed to, with the valve body closure, the Gas time-control valve cut out.Valve body and bottom be connected to that rib-loop is connected or screw connects or Bond is bonding.Mounting groove is arranged at valve body top, and its shape is corresponding with timer lower housing portion shape, during installation, is stuck in the timer lower housing portion.Seal ring and lower seal are housed on the spool, and the end face of body cavity is the inclined-plane, and lower seal closely contacts with the inclined-plane at body cavity top, the sealed valve body inner chamber.Gas in the valve body can be to external leakage, and the air pressure in the valve body is high more, with spool upwards press tight more.Because timer has the quick-break function, this Gas time-control valve also has the quick-break function.
The utility model has the advantages that simple and reasonable for structure, be suitable for regularly closing usefulness with the gas cooker of inflammable gass such as liquid gas, coal gas, avoided owing to forget close that gas cooker takes place be burned, burn out pot, even danger such as breaking out of fire, blast have guaranteed to use the safety of gas cooker.Owing to avoided overtime burning, thereby saved the energy.
Embodiment of accompanying drawings:
Fig. 1 is a kind of Gas time-control valve arrangement schematic representation:
This Gas time-control valve has valve body 1, and a suction port and an air outlet are arranged on the valve body 1, and spool 2 is housed in the valve body 1, and bottom 6 is arranged at the bottom, and bottom 6 and valve body 1 are connected by rib-loop.Be pressed with plain washer 5 between valve body 1 and the bottom 6, spool 2 tops are with two and go up seal ring 8 and lower seal 3.Lower seal 3 closely contacts good seal with the inclined-plane of valve body 1 interior top of chamber.Spring 4 is stuck in the middle of the spool 2 between the thickest section and the bottom 6, and insert in the hole in the middle of the bottom 6 spool 2 lower ends, leading role is arranged in that spool is upper and lower when mobile.A shape and the corresponding mounting groove 7 of timer lower housing portion shape are arranged at valve body top, and during installation, mounting groove is stuck in the timer bottom.The thimble 9 of timer contacts with the top of spool 2, and the thimble of timer is regularly upper and lower to be moved, and just can regulate the timing of Gas time-control valve and close.
Claims (5)
1, a kind of Gas time-control valve, a valve body is arranged, an inlet hole and an air outlet hole are arranged on the valve body, spool is housed in valve body, and the spool top contacts with the timer thimble, it is characterized in that the bottom of valve body lower portion closely is connected with valve body, between the thickest one section spring is housed on bottom and the spool, there is a pilot hole at the bottom center, and insert in the pilot hole spool lower end, between valve body and the bottom plain washer is housed.
2, according to the described Gas time-control valve of claim 1, what it is characterized in that valve body and bottom is connected to that rib-loop is connected, screw connects or Bond is bonding.
