Abstract
The utility model provides a water cutting device for converting high pressure and low pressure, which comprises a drill connector, a sealing cushion, a piston, a sealing ring, a spring, a water cutting device body, a retaining ring and a nozzle, wherein the rear end of the drill connector and the front end of the water cutting device are in threaded connection and are sealed by the sealing ring, and the piston is installed in the rear end of the drill connector. The sealing cushion and the spring are installed at the front end of the piston, and the retaining ring for limiting is installed at the rear end of the piston. A nozzle is arranged on the outer circumferential surface in the middle of the water cutting body in threaded connection. The water cutting device for converting the high pressure and the low pressure adopts the piston to control the flow direction of water, directly utilizes high-pressure water to cut a broaching after low-pressure water is utilized to drill in place, and other water cutting devices are not required to be further installed after drilling for operation. The water cutting device for converting the high pressure and the low pressure is simple in structure and convenient to use so that gas drawing and discharging holes can be better cut and enlarged.
Description
Technical field
The utility model relates to field of mechanical technique, particularly a kind of high-low pressure conversion water cutter.
Background technology
High-low pressure conversion water cutter be coal mine gas pump drainage discharge hole to bore the critical piece that cuts integration apparatus be for through hydraulic slotted liner technique and reaming, it is more unobstructed, thorough that drawing-off gas is got.The high-low pressure conversion water cutter complex structure that prior art provides uses the low-pressure water cutter before the boring during use, other water cutter is installed after boring is again carried out operation, uses inconvenient.
The utility model content
The utility model provides a kind of high-low pressure simple in structure, easy to use conversion water cutter, need not to change different water cutters is installed, with better cutting, expansion gas exhaust discharge hole.
To achieve these goals, the utility model provides following technical scheme:
A kind of high-low pressure conversion water cutter comprises: bit adapter, sealing mat, piston, sealing ring, spring, water cutter body, back-up ring and nozzle, wherein:
The rear end of bit adapter seals through being threaded and passing through sealing ring with the front end of water cutter body, and piston is installed in the inside of the rear end of bit adapter;

The high-low pressure that Fig. 3 provides for the utility model embodiment is changed the user mode figure (high pressure conditions) of water cutter.
The specific embodiment
In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
The utility model embodiment provides a kind of high-low pressure conversion water cutter; Like Fig. 1, Fig. 2 and shown in Figure 3; This high-low pressure conversion water cutter comprises: bit adapter 1, sealing mat 2, piston 3, sealing ring 4, spring 5, water cutter body 6, back-up ring 7 and nozzle 8; Wherein: the front end of the rear end of bit adapter 1 and water cutter body 6 is through being threaded and in addition sealing ring 4 sealings, and piston 3 is installed in the inside of the rear end of bit adapter 1; The front end of piston 3 is equipped with sealing mat 2 and spring 5, and the rear end of piston 3 is equipped with and is used for spacing back-up ring 7; Nozzle 8 is through on the middle part periphery that is threaded in water cutter body 6.In the present embodiment, adopt piston 3 sealings, piston is installed in the inside of bit adapter, opens and closes the hydraulic pressure that flows to bit adapter the place ahead with the elasticity size adjustment of selecting spring.
Preferably, in the foregoing description, said nozzle 8 is 1-3.
Preferably, the outer face of said piston 3 is lower than the cylindrical end face of said water cutter body 6.That is: nozzle adopts invaginating to install, and the outer face of nozzle 3 is lower than water cutter body 6 cylindricals, and nozzle 8 unlikely extension things damaged when water cutter body 6 was rotated in the hole.
In the foregoing description, water cutter body 6 is connected with the high pressure sealing drilling rod through its rear end screw thread.
The high-low pressure conversion water cutter that the utility model provides is installed between drill bit and the brill stalk and uses, and when hydraulic pressure was lower than certain pressure intensity, piston received spring action to open mode, and this moment, water was gone into the inner and piston middle part of bit adapter through the piston rear end orifice flow.The chamber in, the orifice flow that flows into piston nose again goes out the bit adapter front end, flows to drill bit and creeps into cold when hydraulic pressure is higher than certain pressure intensity; Moved forward by the hydraulic action piston, the hole of piston nose gets in the chisel edge hole, and sealing mat is sealed the water that flows to the bit adapter front end; At this moment; Piston full closing state, water realize that by the nozzle radial spray of side the water under high pressure bolt is towards penetrating the cutting reaming.
More than a kind of high-low pressure conversion water cutter that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
Claims (3)
1. a high-low pressure conversion water cutter is characterized in that, comprising: bit adapter, sealing mat, piston, sealing ring, spring, water cutter body, back-up ring and nozzle, wherein:
