Description
Technical field
The utility model content belongs to the pipeline gas technical field, relates to and a kind ofly can overcurrent occur in family expenses and industrial pipeline gas air feed process, the combustion gas sebific duct comes off or burnt the disconnected gas circuit and the self-closing ball valve of combustion gas with hand button self-locking device of anti-misoperation in advance of cutting off automatically when causing the gas leakage situation.
Background technique
In daily life and industrial production, in case gas pipeline generation interface sebific duct comes off, perhaps sebific duct is burnt disconnected and when causing combustion gas to be leaked in a large number, is tended to cause security incident, and this will bring very big harm to the user.In addition, in the family life,, also can bring unnecessary danger on ordinary days to the user because the head of a family nurses situation improper so that children's mistake is opened gas valve.
The model utility content
The purpose of this utility model is the problem that prior art exists is solved, and then provide a kind of structural principle simple, the self-closing ball valve of the combustion gas of reliable performance, the self-closing ball valve of this combustion gas can come off or flow cuts off source of the gas when increasing suddenly automatically at the combustion gas sebific duct, can also when finishing throttle down, realize self-locking with gas, effectively prevent the generation of accident, and can guarantee more reliably that the combustion gas user uses the convenience and the safety of combustion gas.
Be used to realize that the technological scheme of foregoing invention purpose is such: the self-closing ball valve of the combustion gas that is provided has threeway main valve body and operator button that is arranged on the main valve body top by positioning pressuring plate that two ends are provided with suction port and air outlet, suction port one side in main valve body is provided with a valve seat and a valve head support from inside to outside, in valve head carriage center axis hole, connect the valve head bar that is fitted with an inner band elasticity valve head, on the outer bar of valve head bar, be set with the induction spring; The lower end of hand button is fixedly connected with the spiral arm bar of a band center hole and lower end spiral arm location piece by screw, the spiral arm bar is plugged in the positioning pressuring plate center hole, under positioning pressuring plate, be provided with locating slot on the Transverse plane, be provided with self-locking spring in the spiral arm bar center hole, a main valve stem that inserts in the main valve body is housed below self-locking spring, and the main valve stem below is provided with the cut-out Metal Ball.
The main valve stem of the self-closing ball valve of this combustion gas is inserted in the spiral arm bar center hole and can moves up and down therein.
The spiral arm location piece of the self-closing ball valve of this combustion gas can rotate in 90 degree scopes along the spiral arm rod axis, and one 90 degree turning point place of location piece also can embed in the locating slot under the self-locking spring effect corresponding to locating slot, and then implements lock-bit.
The valve head support that is provided with in the self-closing ball valve suction port of this combustion gas, valve head bar, elasticity valve head and induction spring are coaxial installation.
In the practical application, when following two kinds of situations take place when, the self-closing ball valve of this combustion gas will be closed automatically: 1, when the self-closing ball valve rate of discharge of combustion gas raises suddenly and seriously exceeds normal value, the elasticity valve head can and be pushed down valve seat to the motion of valve seat direction and make valve closing under the influence of air-flow; 2, with in the gas process, when suction pressure generation catastrophic fluctuation, because gas produces thrust to the elasticity valve head, compression takes place the induction spring of back causes the elasticity valve head also can push down valve seat to cause air-flow to be cut off.In addition, after the end user throttle down was used in combustion gas, the self-locking spring in the spiral arm bar existed Driving force upwards all the time to the spiral arm bar, and this can make location piece fall in the locating slot on the positioning plate plane, thus the self-locking of implementation and operation hand button.When reusing combustion gas, need downward pressing operation hand button, location piece is extruded capable rotation again can open valve use combustion gas from the locating slot of positioning plate.
Compared with prior art, the utlity model has simple and reasonable, easy to install and use, fabricating cost is cheap, advantages such as Safety performance is reliable, spring and elasticity valve head in the miniature power shut-off means that the valve inlet place is provided with, the unexpected variation of sensitivity induction import step pressure and flow rapidly, when flow and pressure increase suddenly or minimizing, cut off gas channels immediately, eliminated and solved that sebific duct during combustion gas is used comes off or burnt the harm that a large amount of leakages of combustion gas take place when disconnected, also efficiently solve the problem that can not realize self-locking behind the valve closing of combustion gas in using simultaneously, can guarantee the safe handling of combustion gas more effectively.
