Description

A kind of shaft collar of gas storage well
Technical field
The utility model relates to a kind of shaft collar, particularly relates to a kind of shaft collar for gas storage well.
Background technology
The shaft collar of existing well for storage adopts a kind of flange arrangement mostly, it can realize repeated removal, but needs mounting flange, flange and a forging for connecting tubes, simultaneously, flange needs multiple bolt is installed, such structure consumptive material is many and heavy, and cost of production is high, installation and removal inconvenience, and the poor sealing of flange arrangement, easily cause contingency, affect the safe handling of gas storage well, actual needs can not be met.
Utility model content
The utility model object provides a kind of structure simple to overcome the deficiencies in the prior art, the low and shaft collar of the gas storage well of good airproof performance of cost of production.
For achieving the above object, the technical solution adopted in the utility model is: a kind of shaft collar of gas storage well, comprises well head screw shell, well head end plug, well head joint pressure cap, first end plug sealing ring, the second end plug sealing ring and intake and exhaust joint; Described well head screw shell is threaded with the surface pipe on well casing; Described well head screw shell is connected by well head joint pressure cap with between well head end plug; The fitting face top and bottom of described well head screw shell and well head end plug are respectively equipped with first end plug sealing ring and the second end plug sealing ring; Described intake and exhaust joint is connected with well head end plug through well head joint pressure cap.
Preferably, described intake and exhaust joint is four-way connection; Described intake and exhaust joint is provided with air inlet/outlet, leakage fluid dram and mouth for subsequent use.
Preferably, the material of described well head screw shell, well head end plug and well head joint pressure cap is structural alloy steel.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages: the shaft collar of the gas storage well of the utility model scheme, its structure is simple, easy disassembly, and good seal performance, cost of production is low, ensure that the safe handling of gas storage well, meets actual user demand.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further.
Accompanying drawing 1 is the structural representation of the shaft collar of the utility model gas storage well.
Accompanying drawing 2 is the partial enlarged drawing of accompanying drawing 1.
Accompanying drawing 3 is the partial enlarged drawing of accompanying drawing 1.
Wherein: 1, well head screw shell; 2, well head end plug; 3, well head joint pressure cap; 4, first end plug sealing ring; 5, the second end plug sealing ring; 6, intake and exhaust joint; 7, air inlet/outlet; 8, leakage fluid dram; 9, mouth for subsequent use; 10, well casing; 11, surface pipe; 12, low head; 13, blow-off pipe.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
The shaft collar of described in the utility model a kind of gas storage well as illustrated in the accompanying drawings from 1 to 3, comprises well head screw shell 1, well head end plug 2, well head joint pressure cap 3, first end plug sealing ring 4, second end plug sealing ring 5 and intake and exhaust joint 6; Described well head screw shell 1 is threaded with the surface pipe 11 on well casing 10; Described well head screw shell 1 is connected by well head joint pressure cap 3 with between well head end plug 2; Described well head screw shell 1 is respectively equipped with first end plug sealing ring 4 and the second end plug sealing ring 5 with the fitting face top and bottom of well head end plug 2; Described intake and exhaust joint 6 is connected with well head end plug 2 through well head joint pressure cap 3; Described intake and exhaust joint 6 is four-way connection; Described intake and exhaust joint 6 is provided with air inlet/outlet 7, leakage fluid dram 8 and mouth for subsequent use 9; The material of described well head screw shell 1, well head end plug 2 and well head joint pressure cap 3 is structural alloy steel.
The shaft collar of described in the utility model a kind of gas storage well as illustrated in the accompanying drawings from 1 to 3, it adopts well head screw shell to be threaded with the surface pipe on well casing, and be pressed together between well head screw shell and well head end plug by well head joint pressure cap, form one wiper seal, the upper end of well head screw shell and well head end plug fitting face is provided with first end plug sealing ring and constitutes the first seal group simultaneously, the lower end of well head screw shell and well head end plug fitting face is provided with the second end plug sealing ring and constitutes the second seal group, thus ensure that the sealing of the shaft collar of gas storage well, ensure that the safe handling of gas storage well, and avoid use flange arrangement, improve sealing performance, reduce cost of production.
The shaft collar of gas storage well as above, is provided with low head below its well casing, and is also provided with blow-off pipe below well casing.
The shaft collar of gas storage well of the present utility model, its structure is simple, and cost of production is low, and easy disassembly, good seal performance, ensure that the safe handling of gas storage well, meets actual user demand.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
