Be provided with the dust-break sheet in pressure adjusting nut exterior edge face.
Working principle of the present utility model is: liquefied petroleum ga steel cylinder blast main cause is because liquefied petroleum gas (LPG) fills due to the overfill, example: it is 13.5 kilograms that the liquefied petroleum ga steel cylinder that China's laws and regulations requirement is 15 kilograms is limited the quantity of, because the expansion coefficient of liquefied petroleum gas (LPG) is 1: 250, that is to say that 1 liter of liquefied petroleum gas (LPG) can change into 250 liters of gases, if do not stay the expansion space in the steel cylinder, 1 degree centigrade of the every rising of the hull-skin temperature of steel cylinder, the steel cylinder pressure inside increases 2MPa, if reserve certain expansion space in the steel cylinder, 1 degree centigrade of the every rising of steel cylinder surface temperature, pressure in the steel cylinder only increases 0.02MPa, therefore limits the quantity of to fill and can reduce steel cylinder blast problem.This also is that rules and regulations are 80% reason as the standard filling weight of liquefied petroleum ga steel cylinder theoretical displacement.The utility model setting filling valve of limiting the quantity of can fundamentally be realized the problem that liquefied petroleum ga steel cylinder fills by standard.The described filling valve of limiting the quantity of comprises the filling valve valve of limiting the quantity of, the filling valve valve body of limiting the quantity of, the filling valve valve body of limiting the quantity of is provided with float pin, float links to each other with float pin, the filling valve valve of limiting the quantity of is provided with needle, above float pin, be provided with the needle spring seat, the needle spring seat is provided with the through hole with the needle coupling, be provided with bayonet socket with the through hole opposite position on the float pin, the needle spring seat is provided with the needle spring, needle passes the needle spring and touches mutually with float pin with through hole, and the sidewall of the filling valve of limiting the quantity of above the needle spring seat is provided with pore.When liquefied petroleum ga steel cylinder fills, the promotion needle moves forward, and forces the needle length of spring compressed, and the needle end withstands on the float pin, liquefied petroleum gas (LPG) enters in the steel cylinder by the pore of the filling valve valve body side of limiting the quantity of, when the height of the inner liquefied petroleum gas (LPG) of steel cylinder rose, float rose and drives the float pin rotation, when the float height rises to the design liquid level, needle snaps in float pin bayonet socket place, make valve that inlet end is closed tightly, liquefied petroleum gas (LPG) can not enter steel cylinder again, the task that finishing limits the quantity of fills.
Super flow stop valve is installed is when preventing the malfunctioning or conduit failure of pressure governor, a large amount of liquefied petroleum gas (LPG) flow out, and cause disaster.At the pore of valve body and limit the quantity of and be provided with super flow stop valve between the filling valve valve, described super flow stop valve comprises super flow stop valve spool, valve core spring, under the normal condition, between super flow stop valve spool and super flow stop valve valve owing to spring force separates, be in opening state, when in case the malfunctioning or pipe breakage of pressure governor occurring and causing a large amount of gases to flow out, be subjected to the effect of the LPG saturation vapour pressure in the steel cylinder, gas promotes super flow stop valve spool and overcomes the effect of valve core spring power, super flow stop valve spool and super flow stop valve valve closes, the air outlet is closed.
It is under unexpected situation that safety valve is diffused in installation, and the extra-high of outwards discharging in the steel cylinder is avoided the steel cylinder blast.Body wall is provided with Safety relief valve, described Safety relief valve comprises Safety relief valve valve body, Safety relief valve valve pad, Safety relief valve spring seat, pressure regulating spring and pressure adjusting nut, the Safety relief valve valve pad is close proximity to Safety relief valve valve port place, safety is diffused spring seat and is touched mutually with the Safety relief valve valve pad, pressure regulating spring is positioned on the Safety relief valve spring seat, the pressure adjusting nut is threaded with the Safety relief valve body, and the Safety relief valve valve port diffuses the pore that is provided with on the sidewall of air flue and the filling valve of limiting the quantity of by safety and communicates.Inner side surface at the Safety relief valve valve pad is provided with the Safety relief valve sealing gasket, under the pressure spring effect with the Safety relief valve sealing valve port.Be provided with the dust-break sheet in pressure adjusting nut exterior edge face.Under unexpected situation, rise as the steel cylinder temperature, pressure in the steel cylinder also sharply raises, when pressure reaches 2.5 ± 0.2MPa, gas in the steel cylinder is under the superelevation gas pressure, pass the pore and the safety that are provided with on the sidewall of the filling valve of limiting the quantity of and diffuse air flue, the active force that overcomes pressure regulating spring is outwards pushed the Safety relief valve valve pad open, open the Safety relief valve valve port, outwards discharge the extra-high in the steel cylinder, when the pressure in the steel cylinder was reduced to setting value, the Safety relief valve pad was return under the pressure spring effect, and closed safe diffuses the valve valve port.Be provided with the dust-break sheet in pressure adjusting nut exterior edge face, can prevent entering of dust.
Effect of the present utility model is: owing to be provided with the filling valve of limiting the quantity of, super flow stop valve and Safety relief valve on original angle valve, so purpose that can realize limiting the quantity of and fill, limit the quantity of discharging and diffuse safely, have simple in structurely, easy to use, can improve the effect of safety in utilization.
Below in conjunction with drawings and Examples the utility model is further described.
