Abstract
The utility model discloses a safety valve which can close the safety valve automatically when natural gas is cut off and can open the safety valve and keep the on state automatically when the natural gas is supplied. The safety valve for natural gas supply interruption is provided with an air inlet and an air outlet. A rubber body and a leather cup are connected with a return rod. The acting force of the leather cup from a spring is adjusted by a bolt. The utility model is applicable for companies and individuals that use natural gas for heating and cooking.
Description
The utility model is that a kind of day combustion vapour that prevents makes the safety valve of person poultry poisoning or fire.
At present, along with the development and utilization of sky combustion vapour, vapour well, the unit and the individual that utilize a day combustion vapour heating, cook increase thereupon, because of sky combustion vapour tends to interrupt, interrupt the after-combustion head and extinguish, only can not burn when coming vapour again to the vapour of going out, the person poultry poisoning will be caused like this, fire can be caused accidentally.
The purpose of this utility model provides a kind of day and has no progeny and can close automatically in the combustion vapour.Come to open and can keep automatically behind the vapour safety valve of opening state.
The purpose of this utility model is achieved in that steam inlet, steam ouput in shell, rubber body, leather cup are connected with the return bar, and spring is fastened adjustment by adjustment.When steam inlet has vapour, rubber body and housing contacts face make day combustion vapour air pressure can not promote rubber body under the active force of spring, be closed condition, steam inlet and steam ouput are obstructed, when the people spurs the return bar, overcome the active force of spring, driven rubber body and move, steam inlet communicates with steam ouput, a day combustion steam flow mistake is arranged, leather cup pressurized simultaneously because of greater than the rubber body compression area ten times of the compression area of leather cup, drives rubber body and is automatic opening state so leather cup promotes spring, fired in the vapour same day and had no progeny, at this moment leather cup does not have pressurized, the spring handle leather cup, rubber body pushes back closes, thereby can not go out vapour from steam ouput when having reached steam inlet and again vapour being arranged.
Because adopt such scheme, firing the same day has no progeny in the vapour can close automatically, come to open behind the vapour and can keep opening state automatically.
Below in conjunction with accompanying drawing the utility model is further specified.
Figure is the longitudinal section tectonic maps that day combustion vapour interrupts safety valve.
Among the figure: 1, shell 2, shell 3, leather cup 4, spring 5, return bar 6, adjustment bolt 7, rubber body 8, steam inlet 9, steam ouput.
In the accompanying drawings, when steam inlet 8 has vapour, because of can not making day combustion vapour air pressure, the active force of spring 4 promotes a rubber body 7, so, it combustion vapour can not flow to steam ouput 9 from steam inlet 8, when need fire vapour with the sky, spur return bar 5, the active force that has overcome spring 4 drives rubber body 7 and leaves shell 1, it combustion vapour is pressed to steam ouput 9 from steam inlet 8, presses to leather cup 3 simultaneously, because of greater than rubber body 7 compression areas ten times of the compression area of leather cup 3, so, leather cup 3 drives the active force that rubber body 7 have overcome spring 4 automatically and keeps opening state, fires in the vapour same day and has no progeny, when constantly being decreased to the active force that can not overcome spring 4 along with the pressurized of leather cup 3, just automatically rubber body 7 is pushed to be closed condition with the joint of shell 1, adjusting bolt 6 can be according to the active force that fired the size adjustment spring 4 of vapour air pressure in local day.
Claims (1)
- A kind of day combustion vapour safety valve, in shell, there are steam inlet, steam ouput, rubber body, leather cup, return bar, spring, adjustment bolt to be connected in proper order, it is characterized in that: steam inlet is closed with rubber body or is open-minded, rubber body leather cup, return bar are connected, spring to the active force of leather cup by adjusting the bolt adjustment.
