Description
Technical field
The utility model relates to a kind of gas storage well, particularly a kind of heavy caliber gas storage well of good airproof performance.
Background technique
Due to gas storage well, in working order time, inside has higher air pressure, so in the construction of gas storage well, the sealing of gas storage well is had to higher requirement.At present, gas storage well generally includes pit shaft part, be arranged on the air valve of pit shaft part upper end and the hermetic unit of pit shaft part lower end is set, pit shaft lower end normally adopts the form of welding end socket to seal the bottom of pit shaft, adopt the lower end of this form seal shaft, make the sealing of pit shaft lower end tight, and there is certain intensity, can be adapted to the higher pressure in gas storage well inside.
But, adopt when the form seal shaft of pit shaft lower end welding end socket, along with the increase of mineshaft diameter, the weld seam between pit shaft lower end and end socket is just longer, and the difficulty of welding procedure also increases thereupon, and sealing effect can reduce greatly.
Model utility content
The purpose of this utility model is: for existing gas storage well above shortcomings, provide a kind of heavy caliber gas storage well of good airproof performance.
To achieve these goals, the technical solution adopted in the utility model is:
A heavy caliber gas storage well for good airproof performance, comprises pit shaft, and end, the upper and lower two ends of described pit shaft seals respectively and is provided with upper cover and lower seal head, and described upper cover is connected with lower end end thread with the end, upper end of described pit shaft respectively with lower seal head.Upper cover and lower seal head are threaded with pit shaft, have avoided using the mode of welding to be connected between upper cover and lower seal head and pit shaft, and then have avoided due to the bad problem of airtight quality that adopts welding manner to occur.
As preferred version of the present utility model, described pit shaft lower end is also provided with interior end socket, and the outer rim of described interior end socket matches with described shaft in wall.By in pit shaft lower end, interior end socket being set, the outer rim of interior end socket matches with the inwall of pit shaft, plays the effect of seal shaft lower end, has improved the seal of pit shaft lower end.
As preferred version of the present utility model, in the outer rim of described interior end socket, be provided with annular groove, in described annular groove, be provided with seal ring.Further improved the seal of pit shaft lower end.
As preferred version of the present utility model, the part that end, described pit shaft lower end is stretched out in described interior end socket lower end convexes to form seam along the radially outward of described pit shaft, and described seam is covered on end, described pit shaft lower end.Seam covers on the end, lower end of pit shaft, prevents that interior end socket from entering into pit shaft inside completely, reduces pit shaft gas-storing capacity.
As preferred version of the present utility model, between end, described pit shaft lower end and described seam, be provided with packing ring with matching.Between end, pit shaft lower end and seam, packing ring is set, prevents excessive wear between interior end socket and pit shaft and reduce obturation effect, when lower seal head rotates, due to the existence of interior end socket, packing ring does not rotate with outside head, has further improved obturation effect.
As preferred version of the present utility model, the bottom of described lower seal head inwall along described pit shaft radially inwardly protruding form annular boss, described annular boss sidewall matches with the sidewall of described seam.By annular boss sidewall, match with ring-type seam sidewall, further firm interior end socket, improves sealing effect.
As preferred version of the present utility model, on the outer wall of end, described pit shaft lower end, be provided with ring-type breach, in described annular boss extends upward described ring-type breach is coated on, the sidewall of described ring-type breach matches with the sidewall of described annular boss.Ring-type breach by pit shaft lower end matches with the annular boss in lower seal head, improves the steadiness of lower seal head, and while preventing from gas storage well is installed, lower seal head is stressed excessive and skew occurs damage the part that is threaded between lower seal head and pit shaft.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
The utility model adopts upper cover and lower seal head to be threaded with pit shaft, avoided using the mode of welding to be connected between upper cover and lower seal head and pit shaft, and then avoided, due to the bad problem of airtight quality that adopts welding manner to occur, having improved obturation effect.
