Abstract
The utility model relates to an anti-collision crown block control system. The anti-collision crown block control system comprises a gas-storing pump, an anti-collision switch and a three-position five-way valve, wherein the gas-storing pump is communicated with an input terminal of the three-position five-way valve, and two output ends of the three-position five-way valve are respectively communicated with a brake cylinder and a rotary drum through a gas pipe. The three-position five-way valve controls so as to save a relay and a shuttle valve. The anti-collision crown block control system is simple in structure, capable of be adapted to complex environment of an operation site, convenient to repair, and long in service life.
Description
Technical field
The utility model relates to a kind of colliding crown block control system.
Background technology
Be to guarantee the normal production of oil well, the remedial work number of times increases year by year, and remedial work becomes one of the groundwork of producing of recovering the oil, and the colliding crown block control system valve that uses in the at present remedial work is many, and complex structure is fragile, the life-span is short, easy-maintaining not.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, should not damage, the colliding crown block control system of long service life.
The technical solution of the utility model is:
The colliding crown block control system comprises gas storage pump, anti-collision switch, three position five-way valve, and gas storage pump is communicated with the input end of three position five-way valve, and two mouths of three position five-way valve are communicated with brake cylinder and cylinder by tracheae respectively.
Described three position five-way valve is Pneumatic valve, and the anti-collision switch is anti-collision over-winding valve, and anti-collision over-winding valve is communicated with air receiver, and when anti-collision over-winding valve was not worked, the gas in the gas storage pump entered cylinder by three position five-way valve, promoted cylinder work; When anti-collision over-winding valve was worked, the gas in the gas storage pump entered three position five-way valve through anti-collision over-winding valve and promotes valve core movement, and air receiver is communicated with the brake cylinder, air receiver is not communicated with cylinder, thereby the brake cylinder is checked cylinder, and cylinder quits work, and avoids the generation of safety misadventure.
Between described anti-collision over-winding valve and the air receiver valve is set, when valve closing, anti-collision over-winding valve is not worked, thus energy savings.
The beneficial effects of the utility model are: by three position five-way valve control, saved air feeding apparatus and shuttle valve, features simple structure can adapt to the operation field circumstance complication, and is easy to maintenance, long service life.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
1 air receiver, 2 three position five-way valves, 3 valves, 4 anti-collision over-winding valves, 5 brake cylinders, 6 cylinders, 7 tracheaes.
The specific embodiment
The colliding crown block control system comprises gas storage pump, anti-collision switch, three position five-way valve 2, and air receiver 1 is communicated with the admission port of three position five-way valve 2 by tracheae 7, and two air extractor ducts of three position five-way valve 2 are communicated with respectively cylinder 6 and brake cylinder 5.
Gas storage pump also is communicated with valve 3, and valve 3 is communicated with the admission port of anti-collision over-winding valve 4, and the air extractor duct of anti-collision over-winding valve 4 is communicated with the sidewall of three position five-way valve 2.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
