Abstract
The utility model relates to a safety protective valve of pipeline fuel gas. The utility model is provided with a valve cavity which is formed by oppositely buckling a main valve body and a valve cover, wherein the valve cavity is divided into upper and down two cavity bodies through a rubber sealed ripple film sheet; a hand button rod which penetrates through an upper valve cavity body is fixedly connected with the ripple film sheet and an upper armature; the interior of a lower cavity body is provided with a spacing partition table, a rocker arm component and a spring link rod component with a rubber closing plate, wherein one end of the rocker arm component penetrates through the spacing partition table and is connected with a permanent magnet arranged below the upper armature, and the other end of the rocker arm component is connected to the spring link rod component; the outer end of the spring link rod component is provided with the air inlet rubber closing plate; the spacing partition table is provided with a lower armature which is matched with the permanent magnet in a contrapuntal mode. The safety protective valve can automatically close an air path under the condition that the pipeline fuel gas generates overpressure or underpressure or a rubber pipe desquamates, and the utility model plays effect on protecting a fuel gas meter and users' life and possession safe.
Description
Affiliated technical field
The utility model content belongs to the pipeline gas valve technology field, relates to a kind ofly can superpressure, the under-voltage valve of stopping the supple of gas or steam or can close gas circuit during the sebific duct dropping situations automatically occurring at family expenses or industrial pipeline gas.
Background technique
In daily life and industrial production, when the gas pipeline air feed is had no progeny suddenly, people are usually owing to throttle down is forgotten in carelessness, like this after pipeline recovers air feed, combustion gas will be released in a large number, and reasons such as too big or sebific duct comes off are arranged exactly in the air feed process owing to the air outlet flow again, also can cause gas leakage, these phenomenons had both caused the source of the gas waste, and were also easily accidents caused.In addition, because the fault of voltage-regulating system is compressed into the family in can taking place, make the gas meter blast in the equipment air feed process, this can bring very big harm to the user equally.
The model utility content
The purpose of this utility model is the problem that prior art exists is solved, and then provide that a kind of structural principle is simple, easy to install and use, the pipeline gas ultra under-pressure of reliable performance, take off the pipe cut-off valve, this valve can not electricity consumption when unusual occur and closes automatically at pipeline gas pressure, guarantees the safe handling of combustion gas.
Be used to realize that the technical solution of foregoing invention purpose is such: the pipeline gas ultra under-pressure that is provided, take off the pipe cut-off valve and have a valve pocket that constitutes by main valve body and valve gap make-up, there are suction port and air outlet in the main valve body two ends, and valve pocket is divided into up and down two cavitys by the rubber seal convolution diaphragm, a hand button rod is inserted the uuper valve chamber body by valve cover hole, fixedly connected with convolution diaphragm and a upper armature in the hand button rod lower end, in the lower valve chamber body, be provided with spacing every platform, one secondary-rocker assembly and a spring link assembly that has the rubber shrouding, wherein an end of rocker arm assembly passes and spacingly is connected with a permanent magnet that is positioned at upper armature below every platform; the other end of rocker arm assembly is connected on the spring link assembly; an end of spring link assembly is connected bottom the main valve body on the platform rib; the other end is equipped with suction port rubber shrouding, at the spacing lower armature that cooperates with the permanent magnet contraposition that is provided with on platform.This valve is when normal operation, and upper armature and permanent magnet in the valve pocket are in attracting state, and under the rocker arm assembly effect, spring link assembly medi-spring relaxation makes the rubber shrouding suction port of lifting off a seat, and gas is sent to burner by valve pocket.After this when following situation takes place, valve will be closed automatically: 1.. when suction pressure raises suddenly and surpasses normal pressure, rubber seal convolution diaphragm pressurized moves up, it is up to drive upper armature and adsorbed permanent magnet, limit every platform because the stroke range that rocker arm assembly makes progress is limited, the power of convolution diaphragm makes upper armature separate with permanent magnet, permanent magnet fall and with the lower armature adhesive, so driving the spring link assembly, inwardly shrinks rocker arm assembly, make the rubber shrouding seal valve seat suction port, valve closing; 2.. when suction port pressure is very low, because the power that the power on the rubber seal convolution diaphragm attracts less than permanent magnet and downlink iron phase and the restoring force of spring, permanent magnet and lower armature adhesive, rocker arm assembly drives the interior receipts of rubber shrouding and seals valve seat suction port, throttle down; 3.. when too big or sebific duct comes off when the air outlet flow, this moment since the suction port flow less than the air outlet flow, the power that inlet pressure attracts less than permanent magnet and downlink iron phase the buoyancy of rubber seal convolution diaphragm and the restoring force of spring, permanent magnet and lower armature adhesive; rocker arm assembly drives to receive in the rubber shrouding seals valve seat suction port, throttle down.Treat the normal back of air feed as need open valve once more, the mode by manual operation hand button then, make permanent magnet disengaging lower armature and upper armature adhesive up, drive rocker arm assembly and outwards stir the spring link assembly, then make the rubber shrouding suction port of lifting off a seat, open valve, the user could just use gas always afterwards.
Compared with prior art; the utlity model has advantages such as simple and reasonable, easy to install and use, that fabricating cost is cheap, Safety performance is good; it has overcome in the past product and has closed in insecure shortcoming and the production process the often impaired drawback that makes product rejection of spout; efficiently solve gas pipeline and superpressure, the under-voltage and automatic protection problem when taking off the pipe situation occur, guarantee the safe handling of combustion gas.In addition, at gas flow during through valve pocket, because the high magnetic fields of permanent magnet has also played the effect of energy-saving and purifying to the magnetization of combustion gas.
