Abstract
The utility model relates to a safety intelligent valve for gas for pipelines of civil use. A piston is arranged in an intake path arranged at the front end of an air inlet of an air chamber, and the piston is connected with a force arm, a force arm bolt and a rubber diaphragm through an ejector rod. When the safety intelligent valve for gas is used, because air pressure exists in the air chamber, the rubber diaphragm is bulged to drive the force arm so as to push the piston to leave away from the air inlet, and the gas path can be kept expedite. Once the gas supply is interrupted or an output gas hose is fallen off, and air out flow capacity is suddenly enlarged when burning through, the gas pressure in the air chamber is suddenly reduced, the bulging of the rubber diaphragm is eliminated, the force arm is loosened, the air inlet is clogged by the piston under the pushing force of the spring, and the air source is cut off for preventing the gas leakage.
Description
The utility model relates to a kind of gaseous-pressure civil pipeline gas safety device of control automatically that utilizes, and when the airline hose separation-type of combustion gas interrupt delivery and UNICOM's kitchen range burns, can cut off the gas safe smart valve of source of the gas automatically.
Present known civil pipeline gas safety device generally is made of electronic component, because kitchen fume is big, electronic component is often malfunctioning because of corrosion, and needs the external world that electric power is provided, and runs into power failure, just can't come into operation.
The purpose of this utility model provides a kind of pressure controlled gas safe smart valve of pipeline gas of utilizing, and it not only can come off in combustion gas interrupt delivery or sebific duct, cuts off source of the gas when burning automatically, and does not have electronic component, does not need the external world that power is provided.
The purpose of this utility model is achieved in that between valve body bottom and valve body cover a diaphragm of rubber is housed, and forms an air chamber that is hedged off from the outer world.An arm of force bolt is equipped with at the center of diaphragm of rubber, be enclosed within the rear end that is installed in the arm of force in the air chamber, the front end of the arm of force is pressed on the piston mandril, during normal the use, keep normal pressure, diaphragm of rubber pressurized bulging in the air chamber, the drive arm bolt lifts arm of force rear end, arm of force front end is moved down, push piston open, make the gas safe smart valve be held open state.In case the airline hose that interrupts air feed or lead to kitchen range comes off, and when burning, the gas transmission flow is increased suddenly, the air chamber internal pressure descends suddenly, and diaphragm of rubber resets, and the arm of force loosens, and piston is blocked suction port under the effect of spring force, cut off source of the gas.
Owing to adopt such scheme, not only can cut off source of the gas rapidly, prevent gas leakage; and the everything parts all are in valve inner, not corroded by oil smoke, and are sensitive reliable; because of not needing the external world that power is provided, at any time use again, can both be in automatic guard mode.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing: the symmetrical profile tectonic maps of gas safe smart valve.
Among the figure: 1, air input joint 2, piston spring 3, piston 4, arm of force bolt 5, the arm of force 6, valve body bottom 7, valve body cover 8, unlatching handle 9, handle nut 10, diaphragm of rubber 11, air chamber 12, the double-purpose joint of giving vent to anger.
In the drawings, one stifled ventilation dividing plate is arranged in the passage of air input joint (1), be drilled with vent all around, piston (3) is placed in the air input joint passage, one end is furnished with piston spring (2) and withstands on the ventilation dividing plate, and the other end is equipped with sealing gasket and gets lodged on the safe and intelligent valve suction port.The bolt of fixed piston sealing gasket is made piston mandril again, passes the front end that suction port withstands the arm of force (5), and be inserted in the annulus of arm of force bolt (4) bottom the rear end of the arm of force.The middle part of the arm of force is drilled with an aperture, is inserted in movable little axle and is fixed on the supporting frame.Arm of force bolt (4) is fixed on the diaphragm of rubber (10), and stretches out valve body cover (7), puts and open handle (8), and is fixing with handle nut (9).Diaphragm of rubber (10) is contained between valve body bottom (6) and the valve body cover (7), constitute air chamber (11) jointly with the valve body bottom, the double-purpose joint (12) of giving vent to anger is housed in the air outlet of air chamber, make the gas safe smart valve both can be used as first valve of pipeline gas house lead in, connect with gas meter, also can be installed in the gas meter air outlet, directly connect with kitchen range with sebific duct.During use, press and open handle (8), the arm bolt (4) of exerting all one's strength rises, lift the rear end of the arm of force (5), front end is moved down, push piston (3) open, combustion gas promptly enters air chamber (11), diaphragm of rubber (10) bulging under the pressure of combustion gas drives the push rod that the arm of force (5) is pushed down piston (3), makes piston keep smooth open position, in case combustion gas interrupt delivery or the airline hose that leads to kitchen range come off, when burning, the gas transmission flow increases considerably suddenly, and air chamber pressure descends suddenly, the diaphragm of rubber bulging is eliminated, the arm of force loosens, and piston spring promotes piston and blocks the safety valve suction port, cuts off source of the gas.Because the direction that the piston spring elastic force discharges is consistent with the direction of gas flow, and piston is got lodged on the suction port firmly.
