B) spherical valve core is arranged in the air inlet valve pocket, its sphere diameter is greater than the air outlet hole diameter of O-ring seal, and air inlet valve pocket front end is installed filter screen.
Connect switch and be made up of button, depression bar, pressure spring and seal ring, pressure spring is enclosed within on the depression bar, and depression bar and valve pocket jointing are by the dress seal ring.
Voltage-regulation voltage-stabilization closes to be opened by gland, adjustable cap, pressure spring, and pressing plate and diaphragm are formed, and gland has safety vent and is installed in the valve gap top, and adjustable cap below pressure spring is fixed on the pressing plate, and diaphragm is being installed in step place above the valve body below the pressing plate.
Safety regulating valve is made up of nut, depression bar, pressure spring and lever, depression bar is gradient, pass pressing plate and diaphragm center, pressure spring is enclosed within on the depression bar, the depression bar front end is for falling " worker " font body, " worker " font body intermediate groove truck dead lever, balance pivot is fixed on the valve interior wall, and lever top groove is by adorning a sealing plug, and plug is relative with the ell nozzle of air inlet valve pocket.
Owing to take technique scheme, make the utility model technology have following advantage and effect:
A) has switch, voltage-regulation voltage-stabilization, pressure-display, the multiple function that the super flow of gas leakage monitoring is closed;
B) simple in structure, easy to operate, safe and reliable.
Description of drawings:
Fig. 1 is the model utility structural representation.
Below in conjunction with accompanying drawing embodiment the utility model technology is further specified:
Family expenses liquefied synthetic gas safety valve, comprise valve body (1), valve gap (2), spool (19), suction tude (22), steam outlet pipe (24), connect switch, valve is pressed stabilized switch, safety regulating valve and pressure gauge are formed, valve body is divided into air inlet valve pocket and voltage-regulation voltage-stabilization valve pocket by O-ring seal (18), the air inlet valve pocket communicates with suction tude, be oval tube body, O-ring seal is installed in the suction valve cavity rear end, front end is by dress filter screen (20), the centre is spherical valve core (19), and dress is pressed by logical switch in air inlet valve pocket top, by leading to switch by button (11), depression bar (12), pressure spring (13) and seal ring (25) are formed, pressure spring is enclosed within on the depression bar, and depression bar and valve body jointing are connected switch under off working state by the dress seal ring, as shown in Figure 1, spherical valve core (19) is blocked the O-ring seal air outlet hole, connects button when opening the connection switch, pressing, depression bar dials spherical valve from the air outlet, and entering combustion gas, the pressure gauge (not shown) demonstration pressure by the side gets final product proper functioning.When not working, spherical valve core is blocked air outlet hole again, because the spherical valve core diameter is greater than the air outlet hole diameter, so good sealing effect, filter screen can prevent that impurity from entering in the valve pocket.
Side in addition at O-ring seal is the voltage-regulation voltage-stabilization valve pocket, in valve pocket, press the voltage-regulation voltage-stabilization switch of dress by gland (7), adjustable cap (6), pressure spring (14), pressing plate (4) and diaphragm (3) are formed, having safety vent (5) on the gland is installed on the valve gap, adjustable cap below pressure spring is fixed on the pressing plate, diaphragm is below pressing plate, both closely cooperate, diaphragm is installed in step place, valve body top, when regulating pressure, take off gland, rotate adjustable cap with screw-driver from " one " word groove on the adjustable cap, make pressure spring compression, make pressing plate and diaphragm pressurized simultaneously and sink, thereby adjustable pressure, treat the voltage stabilizing of having got back after normal, on the contrary, also can raise flow and pressure.
Safety regulating valve is made up of nut (8), depression bar (9), pressure spring (15) and lever (10), depression bar has constant slope, pass pressing plate and diaphragm center, pressure spring is enclosed within on the depression bar, and the depression bar front end is for falling " worker " font body, " worker " font groove internal fixation lever, balance pivot is fixed on the valve interior wall, by adorning a sealing plug (16), plug is relative with the ell nozzle (17) of air inlet valve pocket, is closed condition in the downward groove on lever top.
During proper functioning, link to each other with the angle valve of steel cylinder with the suction tude of handwheel (21) by sealing phase cushion rubber (23) safety valve, the voltage-regulation voltage-stabilization switch mixes up flow and presses the connection switch, spherical valve core falls, nozzle is passed through in combustion gas, move on the lever, plug and nozzle have distance, and from then on combustion gas enters valve pocket, the gas quantity of pressure gauge indication steel cylinder, when pointing to the pressure gauge red sector, mix up flow, illustrate that a bottle interior combustion gas can only be used can prepare ventilation in two days, local if any gas leakage, gauge hand moves to stop using and overhauls, when surpassing flow, utilize differential principle, spherical valve core combines with O-ring seal (6) at once, close thereby reach automatically, guarantee safety, pressing plate and diaphragm when flow is excessive in the voltage-regulation voltage-stabilization chamber are upwards heaved, and produce the space between band gradient depression bar and pressing plate and the diaphragm, combustion gas meets the crack to flow out from the safety vent (5) on the top cover along depression bar, reaches safety effect.
