Abstract
A kind of pipeline gas self closing stop valve, can to pipeline gas superpressure, under-voltage, overtemperature and super flow leak closes automatically, the utility model is characterized in that: be provided with by bolt in housing, magnet, draw ring, with the overpressure protection parts of locating slot composition, suction port place is provided with and is shut up by pass, pole shutoff, close cushion rubber, close the forward shutdown system of spring and spring detent composition, when gaseous-pressure superelevation or overtemperature, gaseous-pressure in housing rises, upwardly diaphragm, when membrane tension is greater than the linking power of bolt and magnet, bolt is separated automatically with magnet, forward shutdown system is closed, realize superpressure and overtemperature is closed automatically, gaseous-pressure recovers normally, bolt and magnet can be connected merging automatically, safety valve recovers normal, when combustion gas is under-voltage or super flow leaks, the gaseous-pressure in housing sharply declines, and forward shutdown system is closed, and realizes the under-voltage and super flow leakage auto-closing of combustion gas and protects.The utility model structure is simple, functional, safety durable.
Description
Technical field: the utility model relates to the automatic safety device that the accident such as a kind ofly prevent pipeline gas superpressure, under-voltage, overtemperature and sebific duct from coming off, to break causes combustion gas to surpass flow revealing, and the utility model patented technology can be applicable to make pipeline gas special safety valve series product.When pipeline gas occurs that superpressure, under-voltage, overtemperature and super flow leak contingency, device is closed automatically, cuts off source of the gas, prevents the generation of gas leakage and fire explosion, ensures and uses gas safety.
Background technique: along with the development of society, the extensive use of new energy, combustion gas has become industry and necessary fuel energy in life, use in gas process resident, almost there is various leakage everyday, poisoning, catch fire or the generation of explosive accident, particularly because gas pressure regulator, governor pressure regulation is out of control and flexible rubber hose comes off, break, that causes is poisoning, catch fire or explosive accident in the majority, have a strong impact on social harmony to stablize, the application of the utility model patent in domestic gas, effectively can prevent the generation of contingency, reduce property loss, protection life safety, improve the quality of living.
Summary of the invention: the utility model a kind ofly can leak to pipeline gas superpressure, under-voltage, overtemperature and super flow the safety protection device that can automatically close.
For reaching foregoing invention content the technical solution of the utility model be:
A kind ofly can leak to pipeline gas superpressure, under-voltage, overtemperature and super flow the safety valve that can automatically close, be made up of upper cover (12), lower shell body (17), diaphragm (18), annular gasket (19), enable switch, link, lever (23), fixing pin (25), suction port (32), air outlet (15), P cock, overpressure protection parts, loose joint system, forward shutdown system, it is characterized in that: in lower shell body (17) suction port (32) end installing loose joint system, and match with forward shutdown system; Install a forward shutdown system at loose joint system end, and match with lever (23) and fixing pin (25); Between upper cover (12) and lower shell body (17), install diaphragm (18), diaphragm (18) upper end installing annular gasket (19) and link match with enable switch; Diaphragm (18) lower end installing overpressure protection parts are also matched with forward shutdown system by lever (23); Installing one at upper cover (12) lower center place can automatically reset enable switch, and is matched with overpressure protection parts by link; At air outlet (15) end installing P cock, and match with air outlet (15).
The technical solution of the utility model also comprises:
Described pipeline gas self closing stop valve, is characterized in that loose joint system is made up of nut (14), movable connecting piece (30) and rubber ring (31).
Described pipeline gas self closing stop valve, is characterized in that forward shutdown system is shut up (27) by pass, pole shutoff (26), cuts out cushion rubber (28), cuts out spring (29) and spring detent (13) is formed.
Described pipeline gas self closing stop valve, is characterized in that enable switch is made up of pull-button (7), return spring (8) and pull-button sleeve pipe (10).
Described pipeline gas self closing stop valve, is characterized in that overpressure protection parts are made up of bolt (20), magnet (24), draw ring (22) and locating slot (21).
