Abstract
The utility model provides a filling anti-pulling-out protector of a liquid tank truck. The filling anti-pulling-out protector comprises a liquid conveying pipe which is connected with a liquid storage tank and provided with a stop valve, and a hose for connecting the liquid conveying pipe with the tank truck. The filling anti-pulling-out protector is characterized in that a pneumatic film valve is arranged on the liquid conveying pipe behind the stop valve, and connected with a gas supply pipe, an electromagnetic valve is arranged on the gas supply pipe, the electromagnetic valve is connected with a limit switch through a lead, and the limit switch is matched and connected with the tank truck. The filling anti-pulling-out protector of the liquid tank truck has the advantages that after the tank truck enters a filling device and contacts with the limit switch, the loop of the electromagnetic valve is closed so that the gas supply pipeline is switched on, and further the pneumatic film valve is opened to fill the target liquid to the tank truck, and when the tank truck moves to leave from the limit switch, the electromagnetic valve loses power so that the gas supply pipeline is switched off, and as a result, the pneumatic film valve is closed immediately and the conveying of the target liquid is stopped; and therefore, the leakage of dangerous liquid is effectively prevented. Moreover, the filling anti-pulling-out protector of the liquid tank truck is simple in structure, reliable in protection measure and low in cost.
Description
Technical field
The utility model relates to a kind of anti-slip protective gear, and particularly a kind of liquid tank car fills anti-slip protective gear, belongs to pipeline and connects guard technology field.
Background technique
Liquid oxygen, liquid argon, liquid nitrogen belong to low temperature, inflammable, explosive hazardous chemical, and this type of chemical product need to transport with special tank car.The tank car filling equipments such as the liquid oxygen using at present, liquid argon, liquid nitrogen, by pipeline and valve, be directly connected with tank car, in the canned process of reality, once tank car is moved, directly pull and fill pipeline, cause pipeline valve to damage, uncontrollable leak of liquid, hundreds of side and even thousands of sides' liquid leaks in a large number, causes the generation of major accident, causes casualties.To enterprise, bring economic loss.Therefore be necessary prior art to be improved.
Summary of the invention
The purpose of this utility model is to provide a kind of liquid to fill with car and fills anti-slip protective gear.
The utility model completes by following technical proposal: a kind of liquid tank car fills anti-slip protective gear, comprise on its being connected with liquid container the indusion tube with stop valve, the flexible pipe that connects indusion tube and tank car, it is characterized in that the indusion tube being positioned at after stop valve valve is provided with Pneumatic diaphragm valve, this Pneumatic diaphragm valve is connected with air supply pipe, air supply pipe is provided with solenoid valve, solenoid valve is connected with limit switch by wire, limit switch and tank car are matched, while touching limit switch so that tank car enters filled position, connect Electromagnetic Valve Circuit, make solenoid valve obtain electric and open supply air line, and then open Pneumatic diaphragm valve and fill object liquid to tank car, when tank car moves and after departing from limit switch, cut off Electromagnetic Valve Circuit, make solenoid valve dead electricity and close supply air line, Pneumatic diaphragm valve is closed at once, stop the conveying of object liquid, prevent that dangerous liquid from leaking.
Between described indusion tube output terminal and tank car, be provided with the partition wall with through hole, flexible pipe and air supply pipe are connected with tank car liquid entering hole, gas source pipe through the through hole on this partition wall respectively.
Described flexible pipe one end is connected with indusion tube by joint, and the other end is connected with the liquid entering hole on tank car, to carry object liquid to tank car.
Described partition wall through hole outside is provided with fixed block with bayonet, flexible pipe stretches out and is connected with the liquid entering hole on tank car through the through hole on partition wall and the bayonet socket of fixed block, so that when carrying object liquid to tank car, can block flexible pipe by bayonet socket, prevent that tank car from moving and driving flexible pipe and pull internal pipeline, the equipment of damaging.
The utlity model has following advantages and effect: adopt such scheme, can at tank car, enter filled position and touch after limit switch easily, connect Electromagnetic Valve Circuit, make solenoid valve obtain electric and open supply air line, and then open Pneumatic diaphragm valve and fill object liquid to tank car, when tank car moves and after departing from limit switch, cut off Electromagnetic Valve Circuit, make solenoid valve dead electricity and close supply air line, Pneumatic diaphragm valve is closed at once, stop the conveying of object liquid, effectively prevented the leakage of dangerous liquid, have simple in structure, protective measure is reliable, the advantage such as with low cost.Be a desirable anti-slip protective gear in fact.
Accompanying drawing explanation
