Abstract
A self-pressure type high-pressure alcohol-injecting pump is mainly formed from high-pressure plunger cylinder equipped with alcohol suction value and alcohol-injecting valve, pressurization cylinder and reversal valve with inlet pipe and outlet pipe. The interior of reversal valve is equipped with reversal valve core and pilot valve core, it utilizes the self-pressure energy of natural gas in gas pipeline to make the pneumatically-controlled reversal valve core and pilot valve core coupled with piston of pressurization cylinder produce reciprocating alternative movement to drive plunger rod and make it implement alternate reciprocating movement in the high-pressure plunger cylinder, so that it can continuously inject the alcohol liquor into natural gas pipeline. This invented equipment does not consume electric energy, heat energy and natural gas, and can make natural gas pipeline system implement the goal of anti-freezing and normally transmitting gas.
Description
Technical field:
The present invention relates to the variable capacity mechanical pump, specifically a kind of self-pressurizing high-pressure alchol-injection pump, it is specially adapted to petrochemical industry and injects pure liquid in the natural gas transmission pipeline.
Background technique:
We know, in exploitation, in storage and the transport gas pipeline system, because when rock gas step-down temperature step by step reduces, some compound in the rock gas can combine with moisture content and form the icing gas pipeline equipment that stops up of hydrate, have a strong impact on the normal gas transmission operation of natural gas pipeline system, for now, prevent that in petrochemical industry the icing common method of stopping up of natural gas pipeline from having two kinds: the one, adopt the water jacket furnace heating to prevent the method for freezing, it need build water jacket furnace equipment, the cost of equipment height, it is higher to consume energy, need workman's dayroom work, the method operating maintenance administration expenses of this water jacket furnace heating are quite high; Second method is to adopt motor-drive pump to inject antifreeze inhibitor such as pure liquid in natural gas pipeline, stop the generation of hydrate in the rock gas, can thoroughly stop to occur in the gas pipeline the stifled phenomenon of ice, can guarantee the normal gas transmission operation of natural gas tube wire system, this method from the antifreeze inhibitor of pure liquid to gas pipeline that inject also need be set up pumping plant and transmission line equipment, need workman's dayroom work equally, particularly in the collection of China's oil rock gas, storage and transfer line are mostly in the open-air area of not having electricity of outlying desert, it is also higher to set up special-purpose transmission line equipment expense, and workman's dayroom work environment is also extremely abominable, certainly will greatly increase the administration expenses of natural gas transport operation like this.
Summary of the invention:
The present invention proposes a kind of interior rock gas self pressure of gas pipeline that utilizes to drive the high pressure alchol-injection pump injects self-pressurizing high-pressure alchol-injection pump from the antifreeze inhibitor of pure liquid to gas pipeline for power on the basis of existing technology, realize stoping the purpose that forms the icing blocking pipe of hydrate in the rock gas, the self-pressurizing high-pressure alchol-injection pump that the present invention proposes, it mainly inhales pure valve by being equipped with, annotate the high-voltage plunger cylinder of pure valve, pressurized cylinder and suction tude is installed, the selector valve of header of giving vent to anger constitutes, the plunger rod of high-voltage plunger cylinder is connected in the piston in the pressurized cylinder, the supercharging cylinder cap at pressurized cylinder two ends has been done air vent respectively, in the commutation valve pocket of selector valve and the guide's valve pocket respectively device changeover valve core and guide's spool are arranged, the foot piece that is articulated in guide's spool is connected in the piston of pressurized cylinder, the commutation valve pocket has been done the air inlet ring cavity, the commutation ring cavity and the ring cavity of giving vent to anger, guide's valve pocket has been done the air inlet ring cavity, the commutation ring cavity and the ring cavity of giving vent to anger, the commutation valve gap at selector valve two ends is done the commutation air flue that communicates with commutation valve pocket two ends respectively, the commutation pore of doing in the change valve that communicates with the commutation air flue is connected with a commutation ring cavity of guide's valve pocket, the commutation pore of doing in the change valve that communicates with another commutation air flue is connected with another commutation ring cavity of guide's valve pocket, the pilot valve in-core has been done the balance vent, the tracheae that is communicated in a supercharging cylinder cap air vent is connected with a commutation ring cavity of commutation valve pocket, the tracheae that is communicated in another supercharging cylinder cap air vent is connected with another commutation ring cavity of commutation valve pocket, the air inlet ring cavity of commutation valve pocket and the air inlet ring cavity of guide's valve pocket are connected with suction tude, and the ring cavity of giving vent to anger of give vent to anger ring cavity and guide's valve pocket of commutation valve pocket is connected with the header of giving vent to anger.During installation, at first will be inserted in the suction alcohol pipe of inhaling pure valve inserts in the pure liquid basin, the notes alcohol pipe that is installed on natural gas pipeline is connected in the pure valve of notes, constitute the notes alcohol pipeline that seals with high-voltage plunger cylinder, the high-pressure air pipe that will be communicated in natural gas pipeline then is connected in the suction tude of selector valve, connect gas pipeline with being installed on the give vent to anger muffler of header of selector valve in rock gas, constitute the pressure control loop that seals with selector valve and pressurized cylinder, utilize interior rock gas self pressure of gas pipeline can be power, alternately move by the changeover valve core of pneumatic control with guide's spool of pressurized cylinder piston interlock is reciprocal, switch mutually, promote the piston cycle to-and-fro motion in the pressurized cylinder, drive plunger rod iterative motion in high-voltage plunger cylinder, pure liquid can be sucked plunger cavity by inhaling pure valve continuously, go in the natural gas pipeline through annotating the spray of alcohol pipe by annotating pure valve again, realize the purpose of the antifreeze and normal gas transmission of natural gas transmission pipeline system, the present invention utilizes interior rock gas self pressure of gas pipeline can be the work of motivational drive pressurized cylinder, drive is equipped with inhales pure valve, annotate the high-pressure plunger cylinder working of pure valve, spray goes into to prevent the pure liquid of the icing blocking pipe of rock gas in gas pipeline, this installs not consumed power, heat energy and rock gas, energy saving is pollution-free, the automaticity height, safe and reliable to operation, need not the personal management, can greatly reduce the operational and administrative expenses that natural gas storage is carried.
