Abstract
The invention relates to a control system of a ground preventer. The known preventer usually brings very big inconvenience for an operator because a three-position four-way rotary valve on a control platform is operated directly by manpower to control the closing or opening of a ram block for preventing blowing during the drilling. The control device connects the control platform with a driller station through an air pipe, operates the three-position four-way rotary valve on the control platform to reverse through operating a three-position four-way air rotary valve on the driller station, thereby directing the opening or closing of the ram block, and achieving the purpose of controlling the opening or closing of the ram block by the driller station. The invention has the advantages of reasonable structure, good control effect, safety, stability, convenient operation, and the like.
Description
Technical field
The control system of ground preventer that the present invention relates to is used for the control of drilling process preventer, belongs to pneumatic control.
Background technology
Known preventer, generally be in the drilling process, when occurring than hyperbar or greater impact liquid stream in the well, operating personnel must directly pull the 3-position 4-way rotary valve with manpower to console, control opening or closing of ram block by hydraulic oil, bring very big inconvenience to operating personnel.Thereby design a kind of long-range driller's console, allow operating personnel's directly command console work in the service depot.
Summary of the invention
The object of the present invention is to provide a kind of control system of ground preventer, it can realize the Long-distance Control to preventer.
To achieve these goals, the present invention includes: the source of the gas treatment element, Liquefied gas swtich, cut and go up valve, Pneumatic oil pump, straight check valve, oil filter, ball valve, flame-proof electric motor, the bent axle plunger displacement pump, pressure controller, high-pressure ball valve, overflow valve, the double-acting piston cylinder, the 3-position 4-way rotary valve, the decompression overflow valve, the two-position three way rotary valve, accumulator, shock-proof pressure gauge, stop valve, high-pressure ball valve, pneumatic pressure transmitter, the air filtration reducing valve, gas/manual pressure regulating valve, 3-position 4-way cyclostrophic valve, pressure meter, air vent valve, the tracheae plug socket, formations such as tracheae cable.
The 3-position 4-way rotary valve on the console is made in the corresponding control of 3-position 4-way cyclostrophic valve on the driller station.
Connect by the tracheae cable between the 3-position 4-way rotary valve on 3-position 4-way cyclostrophic valve and the console on the driller station.
That the present invention has is rational in infrastructure, control is effective, safety and stability, advantage such as easy to operate.
Description of drawings
Accompanying drawing is principle of the invention figure
In the accompanying drawing, 1,37 is the source of the gas treatment element, 2 is Liquefied gas swtich, 3 for cutting upward valve, 4 is Pneumatic oil pump, 5,12 is straight check valve, 6,10,20 is oil filter, 7,11,13 is ball valve, 8 is flame-proof electric motor, 9 is the bent axle plunger displacement pump, 14 is pressure controller, 15,26 is high-pressure ball valve, 16,23 is overflow valve, 17,39 is the double-acting piston cylinder, 18 is the 3-position 4-way rotary valve, 19 are the decompression overflow valve, 21 is the two-position three way rotary valve, 22 is accumulator, 24,30 is shock-proof pressure gauge, 25 is stop valve, 27,28 is pneumatic pressure transmitter, 29 are the air filtration reducing valve, 31 is gas/manual pressure regulating valve, 32,36,38 is the 3-position 4-way air valve, 33,34,40 is pressure meter, 35 is air vent valve, 41 tracheae plug sockets, 42 tracheae cables.
The right side of tracheae plug socket 41 is the part of driller station in the accompanying drawing, and the left side is the console part, and driller station connects by tracheae cable 42 and 41 tracheae plug sockets with console.
The specific embodiment
As shown in drawings, it is Guaranteed that the present invention is applied to preventer, the 3-position 4-way cyclostrophic valve 36 of at first pulling control gas source switch on the driller station is to opening the position, and the 3-position 4-way cyclostrophic valve of operating simultaneously on the driller station 38 commutates, and compressed air enters console through tracheae cable 42.Corresponding double-acting piston cylinder 17 drives 18 commutations of 3-position 4-way rotary valve.Thereby the hydraulic oil in the oil pipe system drives the ram block motion, and when 3-position 4-way rotary valve 18 was in the pass, hydraulic jack promoted the stuck drilling rod of flashboard, closes oil well.When 3-position 4-way rotary valve 18 was in out, hydraulic jack pulling flashboard was decontroled drilling rod, continues drilling well.Driller station is provided with the current state that shows corresponding and two-way ram cylinder 39, thereby reflects the current state of 3-position 4-way rotary valve 18 corresponding on the console, demonstrates the current state of ram block indirectly.Among the present invention, as long as tracheae cable 42 long enoughs, operating personnel just can open or close control to preventer in convenient and safe operating area far away.Among the present invention, source of the gas treatment element 1,37 Liquefied gas swtiches 2, cut and go up valve 3, straight check valve 5,12, oil filter 6,10,20, ball valve 8,11,13, pressure controller 14, high- pressure ball valve 15,27, overflow valve 16,23, double-acting piston cylinder 39, decompression overflow valve 19, two-position three way rotary valve 21, shock-proof pressure gauge 24,30, stop valve 25, pneumatic pressure transmitter 27,28, air filtration reducing valve 29, gas/manual pressure regulating valve 31,3-position 4-way cyclostrophic valve 32,36, pressure meter 33,34,41, air vent valve 35, tracheae plug socket 41, tracheae cable 42 grades are used for the observation of the pressure of G﹠O and are used for that G﹠O opens and closes and the control of direction in gas circuit and the oil circuit course of work.Pneumatic oil pump 4, fire-proof motor 8, bent axle plunger displacement pump 9 provide the hydraulic oil of enough pressure for whole control device, and pass through accumulator 22 systems stabilisation pressure.
