Description

Timing control valve structure for gas pipeline

Technical Field

The present creation relates to a gas pipeline structure; in particular to a timing control valve structure of a gas pipeline, which can provide the control of the gas supply amount in a certain time.

Background

In the conventional gas pipeline structure, a pipeline is installed at one end of a gas appliance (such as a hot-water heater for a gas stove), and the other end of the pipeline is connected to a gas supply source, so that the gas can be guided and transported to the gas appliance through the pipeline, thereby achieving the purpose of ignition and combustion.

In the area where the population structure is in the aging stage, the old people who are left alone in the family due to the work from young people to foreign people or the old people living alone who are not married and funeral, but the memory of most old people is degraded along with the growth of the old people, so that when people are on fire and cook food, people often forget to cook food at a gas appliance due to no special attention (namely people have side or external factors), especially when people need to stew and cook with small fire, people are more easy to forget to warm due to long cooking time, and the accidental risk that the boiler bottom is completely dry and continues to cause fire occurs.

Since the general gas appliance is directly connected to the pipeline, the gas in the pipeline can flow into the gas appliance to be supplied for standby use, however, when a housewife touches the switch knob of the gas appliance carelessly by turning or walking, the switch knob is often rotated a little bit, so that a small part of the gas can be leaked from the gas appliance in a trace manner until the whole kitchen space is filled with gas with a certain concentration, and further, the accident risk of carbon monoxide poisoning or gas explosion is easily caused.

Therefore, how to develop a safety protection with forced shut-off of gas supply during the use of gas appliances is a technical subject which is a great priority for the industry.

Disclosure of Invention

The main content of the invented gas pipeline timing control valve structure lies in providing a gas pipeline timing control valve structure which is respectively communicated with different pipeline positions by means of gas inlet channel and gas outlet channel of said control valve, and can make the membrane component assembled in said control valve separate its interior into two non-communicated upper and lower gas chambers, said lower gas chamber is respectively mutually communicated with another end of said gas inlet channel and another end of said gas outlet channel, said upper gas chamber is respectively communicated with said gas inlet channel (or lower gas chamber) and gas outlet channel (or lower gas chamber) by means of first and two side channels; the upper air chamber is provided with an electromagnetic valve set which can be communicated with the timing device, and the first leakage-stopping piece and the second leakage-stopping piece which are arranged at the electromagnetic valve set can not be blocked at the air inlet end of the first side channel and the air outlet end of the second side channel at the same time respectively; the timing device is used to start the solenoid valve set to operate, so that the first leakage-stopping member can tightly abut against the first side channel and the second leakage-stopping member can form an open shape with the second side channel, the gas in the lower chamber can be used to rotate to flow out from the inlet end of the exhaust passage to the other side pipeline after the membrane is lifted upwards, therefore, the gas can be supplied to the gas appliance within the set time, and at the same time, the gas required by the gas appliance in use is forcibly closed after the set time is exceeded, so as to prevent accidental fire caused by human forgetfulness or avoid the accidental danger of carbon monoxide poisoning or gas explosion caused by gas leakage caused by accidental collision when not in use, thereby achieving the effect of improving the safety control of the gas appliance during the use of the gas.

Referring to fig. 1 to 2, the present invention relates to a timing control valve structure for a gas pipeline, which at least includes: the control valve 2 is assembled at the pipelines 10 and 11, and the timing device 3 is communicated with the control valve 2; wherein:

the control valve 2 at least includes an air inlet channel 210 communicated with a pipeline 10, a lower air chamber 211 communicated with the other end of the air inlet channel 210, an exhaust channel 212 communicated with the lower air chamber 211 to another pipeline 11, an upper air chamber 221 formed above the lower air chamber 211, a membrane element 23 sandwiched between the upper air chamber 221 and the lower air chamber 211, a spring element 24 positioned between the upper side of the membrane element 23 and the inner wall surface of the upper air chamber 221, a first side channel 26 communicated with the air inlet channel 210 or the lower air chamber 211 to the upper air chamber 221, a second side channel 27 communicated with the upper air chamber 221 to the exhaust channel 212 or the lower air chamber 211, and an electromagnetic valve group 28 installed at the upper air chamber 221;

the solenoid valve set 28 at least comprises a solenoid valve 280, a first magnetic member 281 with a polarity changing function under the excitation of the solenoid valve 280, a second magnetic member 282 moving relative to the first magnetic member 281, a cross rod 283 for the second magnetic member 282, a lug 284 arranged at the cross rod 283 as a fulcrum, first and second leakage-stopping

members

286 and 287 arranged at different positions of the cross rod 283 (i.e. the first and second leakage-stopping

members

286 and 287 are pressed against the first and

second side channels

26 and 27 at different speeds), and a spring 285 for returning the cross rod 283 to the original position, wherein when the solenoid valve set 28 is not started in a normal state, the second leakage-stopping member 287 and the skin member 23 are respectively pressed against the inlet end of the second side channel 27 and the inlet end of the exhaust channel 212, and the first and second leakage-stopping

members

286 and 287 are not pressed against the first side channel 27 and the inlet end of the exhaust channel 212 at the same time, At the two

side channels

26, 27;

the timing device 3 is connected to the solenoid valve set 28 of the control valve 2, and the timing device 3 or the solenoid valve set 28 is connected to the power device 4; the power supply 4 is replaced by a plug, a battery, or a lithium battery;

when the timing device 4 does not start the solenoid valve set 28, since the solenoid valve set 28 is installed in the upper air chamber 221 of the control valve 2, and the first leakage-stopping member 286 located at the solenoid valve set 28 does not block the air inlet end of the first side channel 26, and the second leakage-stopping member 287 located at the solenoid valve set 28 blocks the air outlet end of the second side channel 27, the gas flows from the air inlet channel 210 of the control valve 2 in the pipeline 10, then flows into the lower air chamber 211, flows through the first side channel 26, and then flows into the upper air chamber 221, at this time, the sum of the reverse force of the spring member 24 and the pressure of the gas flowing into the upper air chamber 221, which are borne by the upper surface of the membrane 23 located in the control valve 2, is greater than the pressure of the gas which is borne by the lower surface of the membrane 23, and which is borne by the gas flowing into the lower air chamber 211 only by the lower surface of the membrane 23, so as to ensure that the membrane 24 will block downward at the inlet of the exhaust channel 212, so that the gas that has flowed into the lower chamber 211 cannot flow into the exhaust channel 212 and another pipeline 11 (as shown in fig. 1), thereby achieving the effect of reliably blocking the supply of gas;

when the timer 4 is activated, the timer 4 will transmit a signal to the solenoid 280 of the solenoid valve set 28 to activate (i.e. the solenoid 280 will generate an excitation effect to attract the first magnetic member 281 and the second magnetic member 282), the end of the cross link 283 assembled at the second magnetic member 282 is driven to move upward with the lug part 284 as the center, and the other end of the cross link 283 away from the second magnetic member 282 is driven to move downward (i.e. the cross link 283 takes the lug part 284 as the fulcrum to make a seesaw motion), so that the first leakage prevention member 286 assembled at the cross link 283 moves upward to block the air inlet end of the first side passage 26, at the same time, the second leakage stopper 287 assembled at the cross-link 283 is moved down away from the air outlet end of the second side channel 27 (i.e. in the on state); at this time, the gas pressure in the upper gas chamber 221 immediately flows into the second side channel 27, so that the elastic resilience of the spring element 24 borne by the upper surface of the film element 23 is smaller than the gas pressure borne by the lower surface of the film element 23 from the lower gas chamber 211, so that the film element 23 is pushed away upwards (i.e. a certain distance is kept between the film element 23 and the inlet of the exhaust channel 212), and the gas flowing into the lower gas chamber 211 flows into the inlet of the exhaust channel 212 and then flows out of the other pipeline 11 to supply gas (as shown in fig. 2), so as to effectively control the gas supply amount of the other pipeline 11;

when the set time of the timing device 4 is reached, the timing device 4 will cut off the signal to make the solenoid valve 280 not to continue to operate (i.e. the solenoid valve 280 will not generate excitation to make the first magnetic member 281 and the second magnetic member 282 generate mutual repulsion), the end of the cross link 283 installed at the second magnetic member 282 is driven to move downwards with the lug part 284 as the center, and the other end of the cross link 283 away from the second magnetic member 282 is driven to move upwards (i.e. the cross link 283 makes a seesaw motion with the lug part 284), so that the first leakage preventing member 286 assembled at the cross link 283 moves downward away from the air inlet end of the first side passage 26 (i.e. in a connected state), at the same time, the second leak stopper 287 assembled at the cross connection 283 is moved upward to block the air outlet end of the second side channel 27; at this time, the gas fuel gas already in the first side channel 26 immediately flows into the upper air chamber 221, so that the sum of the reaction force of the spring element 24 and the gas pressure flowing into the upper air chamber 221, which is borne by the upper surface of the membrane element 23, is greater than the sum of the gas pressure from the lower air chamber 211, which is borne by the lower surface of the membrane element 23, and the membrane element 23 is pushed downward to block the inlet of the exhaust channel 212, so that the gas fuel gas flowing into the lower air chamber 211 cannot flow into the inlet of the exhaust channel 212 any more, and the gas fuel gas supply amount (as shown in fig. 1) required for flowing into another pipeline 11 is surely cut off, thereby effectively controlling the gas fuel gas supply effect within a certain time;

by the above structure, the present inventor utilizes whether the timing device 3 can start the solenoid valve set 28 to operate, so as to enable the first leakage-stopping member 286 of the actuated solenoid valve set 28 to tightly abut against the first side channel 26 and enable the second leakage-stopping member 287 and the second side channel 27 to form an open state, so that the gas fuel gas in the lower air chamber 211 can prop up the membrane member 23 and then flow out from the inlet end of the exhaust channel 212 to the other side pipeline 11, or enable the membrane member 23 to tightly block the inlet end of the exhaust channel 212 to block the gas fuel gas from flowing to the other pipeline 11, so that the gas fuel gas can be supplied to the gas appliance within a set time, and the gas fuel gas required by the gas appliance in use can be forcibly closed, thereby preventing an accidental fire caused by a person forgetting accident or preventing carbon monoxide caused by gas leakage caused by an accidental collision when the gas appliance is not in use The accidental danger of poisoning or gas explosion can be avoided, so as to achieve the effect of improving the safety control of the gas appliance during the use of gas.
