Description
Technical field
This utility model relates to wellhead assembly technical field, is specifically related to a kind of fast assembling-disassembling device for fracturing wellhead.
Background technology
The exploitation of coal bed gas can make up the wretched insufficiency of China's clear energy sources, improve energy resource structure, contains low coal mine gas disaster, reduces the methane emptying during mining, improves atmosphere quality.Coal bed gas well realizes gas by drainage and step-down and discharges, so, need when gas production constantly from down-hole to extracardiac pumping, along with the increase of displacement, the pressure of down-hole also can decline therewith, if reservoir is damaged by the stress sensitive of the pressure too fast reservoir of decline and the quick meeting of speed.Meanwhile, along with the increase of displacement, down-hole liquid viscosity also can increase, and these all affect the service life of wellhead assembly, and need rapid-maintenance, and this is accomplished by the wellhead assembly of a kind of fast assembling-disassembling.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, thering is provided a kind of simple in construction, a kind of fast assembling-disassembling device for fracturing wellhead reasonable in design, easy to use, it uses and arranges trocar sheath and inner sleeve in four-way pipe, and water filling coil pipe is set in trocar sheath, having well-separated effect, easy accessibility, pipe fitting segregation ratio is more apparent, and it has easy to use, simple to operate, the features such as practicality is good, with low cost.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of fast assembling-disassembling device for fracturing wellhead described in the utility model, including end pipe and four-way pipe, pipe upper end, the described end is provided with four-way pipe, pipe of the described end is internally provided with inner sleeve and trocar sheath with four-way pipe, described inner sleeve and trocar sheath use coaxial socket join structure, it is provided with water injection pipe dish in described trocar sheath, between described water filling coil pipe and inner sleeve, is provided with thread groove.
Use two to lead to nut between pipe of the described end and four-way pipe to fix, described two lead to nut uses stainless steel material, uses two to lead to nut connecting bottom tube and four-way pipe, has good dismoutability, use stainless steel material simultaneously, there is good connection effect and good steadiness.
Being provided with pressure pad between pipe of the described end and four-way pipe, described pressure pad uses polytetrafluoro material, and the setting of pressure pad ensure that being stably connected with between end pipe and four-way pipe, increase its sealing effectiveness, use the pressure pad of polytetrafluoro material, make full use of its anticorrosion ability, there is good service life.
After using said structure, this utility model has the beneficial effect that its employing of this utility model arranges trocar sheath and inner sleeve in four-way pipe, and arranges water filling coil pipe in trocar sheath, has well-separated effect, easy accessibility, and pipe fitting segregation ratio is more apparent；Being provided with thread groove structure between water filling coil pipe and inner sleeve, embody good stable connection effect, the setting of thread groove simultaneously can be greatly increased it and dismount quick feasibility；And it has easy to use, simple to operate, the features such as practicality is good, with low cost.

Description of reference numerals:
1, end pipe；2, four-way pipe；3, inner sleeve；4, trocar sheath；5, water injection pipe dish；6, thread groove；7, two lead to nut；8, pressure pad.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
As shown in Figure 1, a kind of fast assembling-disassembling device for fracturing wellhead described in the utility model, including end pipe 1 and four-way pipe 2, pipe 1 upper end, the described end is provided with four-way pipe 2, pipe of the described end 1 and four-way pipe 2 are internally provided with inner sleeve 3 and trocar sheath 4, described inner sleeve 3 and trocar sheath 4 use coaxial socket join structure, be provided with water injection pipe dish 5, be provided with thread groove 6 between described water filling coil pipe 5 and inner sleeve 3 in described trocar sheath 4.
Use two to lead to nut 7 between pipe of the described end 1 and four-way pipe 2 to fix, described two lead to nut 7 uses stainless steel material, uses two to lead to nut connecting bottom tube and four-way pipe, has good dismoutability, use stainless steel material simultaneously, there is good connection effect and good steadiness.
Being provided with pressure pad 8 between pipe of the described end 1 and four-way pipe 2, described pressure pad 8 uses polytetrafluoro material, and the setting of pressure pad ensure that being stably connected with between end pipe and four-way pipe, increase its sealing effectiveness, use the pressure pad of polytetrafluoro material, make full use of its anticorrosion ability, there is good service life.
Its employing of this utility model arranges trocar sheath and inner sleeve in four-way pipe, and arranges water filling coil pipe in trocar sheath, has well-separated effect, easy accessibility, and pipe fitting segregation ratio is more apparent；Being provided with thread groove structure between water filling coil pipe and inner sleeve, embody good stable connection effect, the setting of thread groove simultaneously can be greatly increased it and dismount quick feasibility；And it has easy to use, simple to operate, the features such as practicality is good, with low cost.
The above is only better embodiment of the present utility model, therefore all equivalence changes done according to structure, feature and the principle described in this utility model patent claim or modification, all it is included in this utility model patent claim.
