Abstract
The utility model relates to a self -balancing steam compensator. Its technical scheme is: be equipped with left steam inlet in body left side, be equipped with first pressure chamber on left end steam inlet's upper portion, be equipped with the third balancing hole on the upper portion of first pressure chamber, be equipped with the second pressure chamber in left end steam inlet's lower part, be equipped with right steam inlet on the body right side, be equipped with the third pressure chamber on right steam inlet's upper portion, be equipped with first balancing hole in the lower part of third pressure chamber, be equipped with the fourth pressure chamber in right steam inlet's lower part, be equipped with the second balancing hole on fourth pressure chamber upper portion. The beneficial effects of the utility model are that: through the utility model discloses, automatic balance power increases along with the increase of heat expansion power to reach automatic balance's purpose, overcoming spring reaction force balancing unit, to be subject to the spring coefficient of elasticity limited, the unable drawback that realizes automatic balance, and self -balancing steam compensator simple structure conveniently makes and uses, and factor of safety, reliability very improve.
Description
Technical field
The utility model relates to a kind of steam expansion loop, particularly a kind of self-balancing type steam expansion loop.
Background technology
At present, the steam injection packer of domestic use adopts thermometal sheet or spring steel wire as hot action element substantially, under the effect of steam, toggle speed is slow and deformation force is little, be difficult to promote cartridge, thus weak effect is set, the drawback that after adopting spring element to also have steam injection to complete, packing element cannot shrink simultaneously, brings the risk of Ka Jing.And sealing performance between compensation steam injection packer body and central tube is poor, often damages seal when packer body slides, cause seal failure.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of self-balancing type steam expansion loop.
Its technical scheme is: comprise the first balancing gate pit, left steam inlet, second balancing gate pit, first balance pipe, 3rd balancing gate pit, right steam inlet, 4th balancing gate pit, second balance pipe, body, 3rd balance pipe, 4th balance pipe, left steam inlet is provided with on the left of body, the first balancing gate pit is provided with on the top of left end steam inlet, the 3rd balance pipe is provided with on the top of the first balancing gate pit, the second balancing gate pit is provided with in the bottom of left end steam inlet, right steam inlet is provided with on the right side of body, the 3rd balancing gate pit is provided with on the top of right steam inlet, the first balance pipe is provided with in the bottom of the 3rd balancing gate pit, the 4th balancing gate pit is provided with in the bottom of right steam inlet, the second balance pipe is provided with on the 4th top, balancing gate pit.
Above-mentioned left steam inlet is twin flue, and right steam inlet is twin flue, and the first balance pipe is identical with the second balance pipe size, and it is identical that the 3rd balance pipe and the 4th balances hole size.
The beneficial effects of the utility model are: pass through the utility model, autobalance power increases with the increase of heat expansion power, thus reach self balancing object, overcoming spring reaction thrust balancing device, to be limited to the elastic coefficient limited, self balancing drawback cannot be realized, self-balancing type steam compensator structure is simple, and convenient manufacture and use, safety factor, reliability greatly improve.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: the first balancing gate pit 1, balancing gate pit 3, first, left steam inlet 2, second balance pipe 4, the 3rd balancing gate pit 5, right steam inlet 6, the 4th balancing gate pit 7, second balance pipe 8, body 9, the 3rd balance pipe 10, the 4th balance pipe 11.
Detailed description of the invention
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises the first balancing gate pit 1, left steam inlet 2, second balancing gate pit 3, first balance pipe 4, 3rd balancing gate pit 5, right steam inlet 6, 4th balancing gate pit 7, second balance pipe 8, body 9, 3rd balance pipe 10, 4th balance pipe 11, left steam inlet 2 is provided with on the left of body 9, the first balancing gate pit 1 is provided with on the top of left end steam inlet 2, the 3rd balance pipe 10 is provided with on the top of the first balancing gate pit 1, the second balancing gate pit 3 is provided with in the bottom of left end steam inlet 2, right steam inlet 6 is provided with on the right side of body 9, the 3rd balancing gate pit 5 is provided with on the top of right steam inlet 6, the first balance pipe 4 is provided with in the bottom of the 3rd balancing gate pit 5, the 4th balancing gate pit 7 is provided with in the bottom of right steam inlet 6, the second balance pipe 8 is provided with on the 4th top, balancing gate pit 7.
Wherein, left steam inlet 2 is twin flue, and right steam inlet 6 is twin flue, and the first balance pipe 4 is identical with the second balance pipe 8 size, and the 3rd balance pipe 10 is identical with the 4th balance pipe 11 size.
Pass through the utility model, autobalance power increases with the increase of heat expansion power, thus reach self balancing object, overcoming spring reaction thrust balancing device, to be limited to the elastic coefficient limited, self balancing drawback cannot be realized, self-balancing type steam compensator structure is simple, and convenient manufacture and use, safety factor, reliability greatly improve.
The above, be only part preferred embodiment of the present invention, any those of ordinary skill in the art all may utilize the technical scheme correct of above-mentioned elaboration or are revised as equivalent technical scheme.Therefore, any simple modification of carrying out according to technical scheme of the present invention or substitute equivalents, belong to the scope of protection of present invention to the greatest extent.
