Summary of the invention
In order to overcome original down-hole drilling water filling plugging device Problems existing and deficiency, the utility model provides a kind of modified down-hole drilling water filling plugging device, still the unidirectional adjustable pressure control valve of mechanical spring structure is adopted, retain the feature that mechanical spring structure is simple, practical, but change its structure design, make it to become single loop plugging device completely.The major measure taked: one is the installation site and the mode that change pressure valve, installs unidirectional adjustable pressure control valve from cage construction inside and changes outside installation into; Two is remove the water filling port on the water-injecting cavity tube connector of plugging device in application number 201320751368.2 patent document; Three is save plugging device extension tube attached in application number 201320751368.2 patent document; Reach simplification structure, put forward high performance object.
Technical solutions of the utility model are as follows:
Modified down-hole drilling water filling plugging device is made up of metal frame main body, unidirectional adjustable pressure control valve and two shutoff capsules, wherein metal frame main body is made up of joint one to joint five, shutoff lumen, tube connector, silk braid and guiding conehead component, is connected between each component by screw thread; Shutoff capsule set is at metal frame main body two ends and sealed by joint ring, forms shutoff chamber; Two shutoff chambeies are directly communicated with by tube connector, and tube connector side is without perforate; Pressure valve adopts mechanical spring structure, and be arranged in the valve pocket outside joint three, delivery port outwards directly enters water-injecting cavity.
Joint three in above-mentioned metal frame main body is processed with one or more valve pockets, is wherein provided with pressure valve.
The complex of the available joint three of the joint two in above-mentioned metal frame main body and joint four replaces.
The utility model has following Advantageous Effects:
The utility model is by changing installation site and the mode of unidirectional adjustable pressure control valve, not only change the double loop water flooding regime that original plugging device uses, save swollen loop, but also eliminate the extension tube attached of water block device itself, make it to become single loop plugging device completely, and structure is more simple, processing is more prone to, more convenient to operate, work is more reliable, and efficiency improves more.

Detailed description of the invention
Modified down-hole drilling water filling plugging device according to Fig. 1, is made up of metal frame main body, pressure valve (13) and two shutoff capsules (11).Metal frame main body comprises joint one (1), shutoff lumen (2), joint two (3), tube connector (4), joint three (5), joint four (6), joint five (7), silk braid (9) and guiding conehead (8) component and forms, and is connected between each component by screw thread; Shutoff lumen (2) is processed with filling port (10); Pressure valve (13) is arranged in the valve pocket of joint three (5); Shutoff capsule (11) is enclosed within metal frame main body two ends and is sealed by joint ring (12), forms shutoff chamber.
Metal frame main body is the critical piece of machine-building, and each element size specific design of metal frame main body is as shown in Fig. 2 to Figure 10; Capsule size specific design as shown in figure 11.Metal frame main body is not isometrical cylindrical structural, and length is about 1400mm, maximum gauge 76mm.Each component silk mouth machining accuracy will reach water-tight requirement under 1.0MP pressure.Rubbing because metal frame main body operationally can produce with hole wall rock and often will contact water, affecting application life for preventing from getting rusty, formal product should adopt 304 stainless steel processing.
Shutoff capsule (11) is inserted in metal frame main body two ends by joint one (1) and joint five (7) end, then utilize joint ring (12) to capsule two ends press seal, and carry out termination fix by silk braid (9) and the conehead (8) that leads.Certain gap should be reserved between joint ring (12) and joint end face, be convenient to dismantle joint ring in the future.
Pressure valve (13) adopts mechanical spring structure, has uniaxial pressure tunable performance, and has the advantages such as structure is simple, size is little, safe and reliable, durable in use, easy replacing, low cost of manufacture.Pressure valve (13) is arranged in two valve pockets of joint three (5), is made up of spool, spring, triplasy internal thread regulating block.Changing spring pressure, thus adjustable pressure valve (13) opening pressure by changing regulating block position, ensureing that the capsule bulbs of pressure control in suitable size.Regulating block may cause position to change by the impact of water at work, and the measures such as metal-to-metal adhesive can be adopted to be fixed, in order to avoid affect the change of opening pressure value.
The operating principle of plugging device is: first water under high pressure enters lower shutoff chamber by water inlet (14), then enters upper shutoff chamber again through tube connector (4), and two shutoff chambeies are directly communicated with by tube connector (4), have identical hydraulic pressure.Under water under high pressure effect, two shutoff capsules (11) will constantly be expanded so that with drill hole wall close contact, in will hole, the sealing of water block device two ends, forms middle closed water-injecting cavity.When pressure is increased to a certain degree, when reaching the opening pressure of pressure valve (13), pressure valve (13) will be opened, and water under high pressure enters water-injecting cavity from shutoff chamber.When in holing, formation fracture exists crack, current can flow into stratum further, cause and leak; When stratum does not exist crack in holing, when current reach certain homeostasis pressure, then can stop flowing, maintain high pressure without flow status.Observe the instrument on water filling console, during stability of flow on the dirty scale of homeostasis pressure, read this section of water filling seepage flow value, this can differentiate cranny development situation.
