Abstract
Provided is a safety protection device of a gas generator set, for preventing an indoor gas transmission pipe from leaking gas. The device is installed outdoors, and a negative pressure gas supply method is used. When a set operates normally, gas pressure in a gas pipeline is maintained to be lower than atmospheric pressure. When the bad sealing condition occurs to the gas pipeline, gas in the pipe would not leak out of the pipe, so as to thoroughly solve a safety problem of gas leakage caused by bad sealing of the indoor pipe of the gas generator set. The safety protection device is simple in structure and is reliable and durable.
Description
Technical field
Prevent the safety protection device that gaseous fuel leaks, be applicable to indoor pipeline gas power generating equipment.
Background technique
The pipeline gas generator set of existing indoor use, during indoor fuel gas transportation pipeline poor sealing, gaseous fuel will leak out indoor, at indoor formation inflammable mixture, combustion explosion phenomenon will be there is when running into burning things which may cause a fire disaster, become the safety problem of indoor fuel gas generating.
Summary of the invention
The object of the invention is: the possibility thoroughly eliminating jet dynamic control indoor fuel gas conveyance conduit gas leakage fuel, solve indoor fuel gas generator set because of indoor gas pipeline and leak the safety problem causing combustion explosion.
The present invention is made up of safety protection body, diaphragm, valve; Safety protector is arranged on outdoor; Safety protection body is disc-shaped structure, has inner chamber, and inner chamber installs diaphragm, and diaphragm is separated into gaseous-pressure room and air pressure chamber inner chamber, the safety protection body of one end, gaseous-pressure room has combustion gas delivery outlet and combustion gas delivery pressure regulating valve; Combustion gas delivery outlet is connected with indoor fuel gas conveyance conduit; Combustion gas delivery pressure regulating valve exports on the safety protection body between entrance and gaseous-pressure room in combustion gas; Combustion gas inlet opening is connected with outdoor gas conveyance conduit; Its center has connecting rod, and one end of connecting rod is fixed on its center, and the other end of connecting rod installs control valve sheet, and control valve sheet is positioned on the valve of one end, combustion gas inlet opening; Air pressure chamber is communicated with air.
Contrast with existing similar security means, the present invention goes to solve the safety problem that indoor fuel gas conveyance conduit leaks combustion gas by the way of gas supply pipe pipeline sealing property in enhanced room, but by changing the way of indoor fuel gas conveyance conduit inner air pressure, thus change the direction of leakage current, ensure that combustion gas can not to pipeline external leakage when indoor fuel gas conveyance conduit poor sealing, stop because indoor fuel gas conveyance conduit poor sealing is to the possibility of external leakage combustion gas, thorough solution because of indoor fuel gas conveyance conduit poor sealing, the safety problem caused.
Accompanying drawing explanation
Accompanying drawing 1 is the cross-sectional view of " safety protector for jet dynamic control building gas pipe, service pipe, indoor pipe ".
Embodiment
See accompanying drawing 1, the present invention is made up of safety protection body 1, diaphragm 3, valve 7; Safety protector is arranged on outdoor; Safety protection body 1 is disc-shaped structure, has inner chamber, and inner chamber installs diaphragm 3, and diaphragm 3 is separated into gaseous-pressure room 2 and air pressure chamber 8 inner chamber, the safety protection body of one end, gaseous-pressure room 2 has combustion gas delivery outlet 9 and combustion gas delivery pressure regulating valve 7; Combustion gas delivery outlet 9 is connected with indoor fuel gas transportation pipeline; On the safety protection body of combustion gas delivery pressure regulating valve 7 between combustion gas inlet opening 6 and gaseous-pressure room 2; Combustion gas inlet opening 6 is connected with outdoor fuel gas transportation pipeline; There is connecting rod 4 at diaphragm 3 center; One end of connecting rod 4 to be fixed in diaphragm 3 in the heart, and the other end of connecting rod 4 installs regulating valve sheet 5; Regulating valve sheet 5 is positioned on the valve 7 of one end, combustion gas inlet opening 6; Air pressure chamber 8 is communicated with air.
Time static, because diaphragm unit self-gravity action makes regulating valve sheet 5 that valve 7 is closed, there is the combustion gas of pressure (higher than barometric pressure) that gaseous-pressure room 2 cannot be entered in outdoor gas pipeline, also nature cannot enter indoor fuel gas transportation pipeline, atmospheric pressure in indoor fuel gas conveyance conduit equals atmospheric pressure, and the combustion gas in indoor fuel gas conveyance conduit would not automatically in delivery chamber, when gas engine works, the intake vacuum of gas engine (possesses " air, combustion gas incoming pressure balace weight " gas engine, patent No. ZL200610077522.7), make gaseous-pressure in indoor fuel gas conveyance conduit lower than atmospheric pressure, the atmospheric pressure of gaseous-pressure room 2 is lower than the atmospheric pressure of air pressure chamber 8, diaphragm 3 produces pressure difference between two sides, this pressure difference produces the active force moved upward on diaphragm 3, promote regulating valve sheet 5 by connecting rod 4 to move upward, open gas valve 7, combustion gas in outdoor gas conveyance conduit is through valve 7, gaseous-pressure room 2, combustion gas delivery outlet 9 flows into indoor fuel gas conveyance conduit supply engine and uses, the precondition moved upward due to diaphragm 3 is that the atmospheric pressure of gaseous-pressure room 2 is lower than atmospheric pressure, so safety protector ensure that gaseous-pressure in indoor fuel gas conveyance conduit is lower than atmospheric pressure, when indoor fuel gas conveyance conduit poor sealing, the flow direction of leakage current flows in fuel gas transportation pipeline from fuel gas transportation pipeline, combustion gas in fuel gas transportation pipeline outside outflow conduit, would not achieve object of the present invention.
