Description
The utility model belongs to and can make gas-liquid adjusting control valve in the improvement, particularly special cylinder of car combustion engine fuel supplying device of fuel with liquefied petroleum gas (LPG).
In order to protect urban environment, reduce of the pollution of the tail gas of motor vehicle emission to environment.At present, progressively promoting single gasoline is that the automobile improvement one-tenth of fuel can be fuel with gasoline both, can use the dual-fuel automobile of liquefied petroleum gas (LPG) as fuel again.Using liquefied petroleum gas (LPG) is special cylinder and liquid gas pressure reducing regulator as the key device of fuel, and the liquid in-out control valve on special cylinder is supplied with pressure reducing regulator with liquid lng, and the gaseous state gas after second depressurized is supplied with car combustion engine and used.Its deficiency is that the liquid in-out control valve feed liquor control on the special cylinder is quantitatively inaccurate, can only provide liquid lng for pressure reducing regulator.Liquid lng vaporization ratio difficulty can't be started car combustion engine in the winter time, must increase Electric heating appliance on the liquid gas supply system, enters the depletion regulator after making liquid lng gasification, and car combustion engine is started smoothly.
The purpose of this utility model is to provide a kind of gas-liquid adjusting control valve, can provide liquid liquefied petroleum gas or gaseous state petroleum gas for pressure reducing regulator as required.Need not in the winter time on the liquefied petroleum gas (LPG) supply system, to set up Electric heating appliance, just can directly provide gaseous state petroleum gas, car combustion engine is started smoothly to pressure reducing regulator, and quantitatively accurate, safe and reliable toward the interior liquid feeding of special cylinder.
The utility model is achieved in that a kind of gas-liquid adjusting control valve, comprise and being provided with into, air outlet and advancing, the valve seat of liquid outlet, the uniform inlet opening that one-way valve is housed that is being provided with on the periphery of the discoid valve seat that has the attachment hole flange, the feed liquor modulating valve, the feed flow hole of flow control valve is housed, the feed flow modulating valve, safety valve, the air outlet hole and the modulating valve of giving vent to anger, wherein the spool of feed liquor modulating valve is being controlled the switch in feed liquor duct, the float assembly is being set on the bottom surface of valve seat, liquid outlet opening and catheter, liquid outlet opening is communicated with inlet opening, the crank arm rotary column of end of float is installed in the rotary column hole of valve seat, the end face of liquid outlet opening matches with caulking gum piece on float is cranked arm, catheter is communicated with the feed flow duct, the spool of feed flow modulating valve is being controlled the switch in feed flow duct, the duct of air outlet hole and safety valve all is communicated with the rotary column vestibule of valve seat, the spool of modulating valve of giving vent to anger is being controlled the switch in the duct of giving vent to anger, and the lower end surface of valve seat is provided with the seal ring that matches with the steel cylinder mouth.
During use, the bolt by the flange attachment hole is installed in gas-liquid adjusting control valve fit sealing on the steel cylinder mouth.When gas station adds liquefied petroleum gas (LPG), air filling gun is aimed at special-purpose valve, open the feed liquor modulating valve then, liquid gas backs down one-way valve from inlet opening and flows in the steel cylinder from liquid outlet opening, when liquid level in the steel cylinder reaches the height of regulation, float floats, and the caulking gum piece on float is cranked arm seals liquid outlet opening, reaches the purpose of feed liquor again.Liquid feeding finishes, and the one-way valve return is closed inlet opening automatically, and liquid gas can not flow backwards, and the feed liquor modulating valve can cut out for the sake of security.When needing feed flow, open the feed flow modulating valve, liquid gas flow to the feed flow hole through catheter, flow control valve on the feed flow hole flows out from feed flow outlet, uses for pressure reducing regulator, when not needing feed flow, close the feed flow modulating valve, flow control valve cuts out automatically if the feed flow pipeline ruptures suddenly.When the gas pressure in the steel cylinder surpassed rated pressure, the pressure release effect was played in safety valve work, and after pressure reduced, safety valve cut out.When start-uping a car internal-combustion engine in the winter time, open the modulating valve of giving vent to anger, gas flows out from air outlet hole and flow to pressure reducing regulator through solenoid valve, and car combustion engine is started smoothly.When not needing air inlet, can close modulating valve.
