Abstract
The present invention relates to an automatic safety protection pressure regulator for gas. It includes an upper cover gas chamber and a pressure-regulating gas chamber which are separated by a flexible rubber cover; two ends of pressure-regulating gas chamber are equipped with gas inlet tube and gas outlet tube, a clamping plate is positioned in the flexible rubber cover and is coupled with flexible rubber cover, between the clamping plate and upper cover arm a pressure-regulating spring is set. Besides, it also includes the components of pressure bar, deformation gas bag and reset spring, etc. Said invention also provides the concrete structure of the above-mention every component, and also provides its working principle.
Description
Affiliated technical field
The present invention relates to a kind of automatic protective pressure regulator for fuel gas.
Background technique
At present, the use popularity rate of China resident family combustion gas is more and more higher, combustion gas brings numerous simultaneously also dangerous constantly easily securities of the lives and property of people to people, now because various security incidents such as the gas leakage that the use combustion gas causes, poisoning, fire, blast are also increasing.Although on market, also occurred some security personnel's products of developing out at gas pressure regulator, governor safety at present, but these products all exist the defective that can not be ignored: what have has introduced combustion gas gas sensing electronic equipment in structure, its structure is complexity but also impracticable not only, in case do not had electricity will lose all protection functions; What have only can report to the police when the gas leakage accident takes place and can not cut off source of the gas automatically.Therefore, we can say in existing pressure governor product, the gas leakage if in a single day its inner skin lid breaks, gas leakage just can not stop voluntarily, and this has brought serious threat for security of the lives and property of people.
Summary of the invention
The general gas pressure governor can not cut off the problem of source of the gas automatically in the prior art when leaking gas in order to overcome, the invention provides a kind of automatic protective pressure regulator for fuel gas, this automatic protective pressure regulator for fuel gas simple in structure, gas leakage the time need not external force and the power supply supply can be cut off source of the gas voluntarily, and is highly sensitive, safe and reliable.
The technical solution adopted for the present invention to solve the technical problems is: comprise upper gas-covering chamber and the pressure chamber separated by flexible skin lid, the two ends of pressure chamber are provided with suction tude and steam outlet pipe, clamping plate are positioned in the flexible skin lid and with flexible skin and cover interlock, be provided with pressure adjusting spring between clamping plate and the last tegmental wall, the depression bar that the clamping plate connecting rod interlock of flexible skin lid below is movably hinged, the capping cap of depression bar end matches with the outlet end of suction tude, flexible skin lid is the air chamber of a sealing, and be communicated with distortion air bag in being arranged on pressure chamber, the distortion air bag is pressed against pulling of Returnning spring of band and buckles a side, pull an end of button and push down security personnel's spring, security personnel's spring is relative with an end of depression bar.
In the guide groove of underpart activity orientation in pressure chamber of clamping plate connecting rod.
The vent that on last tegmental wall, is provided with.
The present invention can eliminate the security incident of breaking and leaking gas and cause because of gas pressure regulator, governor skin lid, and not need any external force and power supply supply by above-mentioned specific design, has simple in structure, highly sensitive, safe and reliable advantage.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present invention is described.
Accompanying drawing is a structural representation of the present invention.
As shown in the figure, the present invention includes upper gas-covering chamber 2 and the pressure chamber 3 separated by flexible skin lid 1, the vent 18 that on last tegmental wall 7, is provided with, the two ends of pressure chamber 3 are provided with suction tude 4 and steam outlet pipe 5, clamping plate 6 are positioned in the flexible skin lid 1 and with flexible skin and cover 1 interlock, be provided with pressure adjusting spring 8 between clamping plate 6 and the last tegmental wall 7, the depression bar 10 that clamping plate connecting rod 9 interlocks that flexible skin covers 1 below are movably hinged, in the guide groove 17 of the underpart activity orientation of clamping plate connecting rod 9 in pressure chamber 3, the capping cap 11 of depression bar 10 ends matches with the outlet end of suction tude 4, flexible skin lid 1 is the air chamber 12 of a sealing, and be communicated with distortion air bag 13 in being arranged on pressure chamber 3, distortion air bag 13 is pressed against pulling of Returnning spring 14 of band and buckles 15 1 sides, pulls an end of button 15 and pushes down security personnel's spring 16, and security personnel's spring 16 is relative with an end of depression bar 10.Under user mode, automatic protective pressure regulator for fuel gas is received on the gas cylinder, open the angle valve of steel cylinder, have a large amount of combustion gas and enter pressure chamber 3 through inlet hole this moment, 1 whole can upwards heaving rapidly, the upper gas-covering chamber's shell wall above the two ends of clamping plate 6 withstand on and the stagnation of rubber flexible skin lid.When leakage has taken place for a certain reason for the air chamber 12 of rubber flexible skin lid 1, at this moment, gas in the distortion air bag 13 can replenish by air chamber 12, the 13 decompression contraction deformations of distortion air bag, under the effect of Returnning spring 14, plate button 15 can be moved to the right rapidly, the other end of plate button 15 is broken away from security personnel's spring 16, in the moment of taking place to break away from, original security personnel's spring 16 that always is in confined state can flick and head on tightly depression bar 10 rapidly finally can make capping cap 11 tightly seal the outlet end of pushing down suction tude 4 downwards, thereby the cut-out source of the gas stops combustion gas to continue to enter pressure chamber through inlet hole, finally realizes the function of automatic protecting.For fear of taking place, automatic protective pressure regulator for fuel gas in long-term using process, may bring some negative effects to the pressure regulating performance and the product itself of pressure governor because of variation such as the temperature of pressure governor outside air, air pressure, humidity, we have designed vent 18, so that make upper gas-covering chamber 2 and the outer air of pressure governor can often carry out " gas exchange ".Even do not increase design vent 18, just upper gas-covering chamber 2 is in closed state, at this moment still proper functioning in the same old way of automatic protective pressure regulator for fuel gas.
