Abstract
The utility model discloses a device, which is arranged on a flow pipeline and is used to prevent liquid flow backwards. The utility model particularly discloses a detachable check valve, which is characterized by comprising a three-way valve boy, wherein two ways of the three-way valve boy serve as a liquid inlet pipe and a liquid outlet pipe, and a screwed plug is moveably mounted at the another way; a baffle central post is movably mounted at the center of a support frame; a baffle is connected to the upper end of the baffle central post; an adjusting nut is arranged at the lower end of the baffle central post; a spring sleeved outside the baffle center post is arranged between the support frame and the adjusting nut; and a baffle seat is arranged on the inner wall of the liquid inlet pipe. The utility model has the advantages that the detachable check valve has a simple structure, is economic and practical; and since the detachable screwed plug is designed, so that fittings can be conveniently detached, replaced and repaired when the sealing property of the check valve gets bad after being used for a long time, the operation is convenient, and the operation is economical and practical.
Description
Technical field
The utility model relates to the device that prevents on a kind of flow process pipeline that liquid from flowing backwards, particularly a kind of removable one-way valve.
Background technique
The one-way valve that uses on the oil well at present is that the ball formula is self-contained one-piece type basically, generally be installed in the metering room through electrogas welding after, or heating furnace stove leg place.It exists shortcoming to be: then be difficult for changing once installing, be difficult for the quality of inspection performance, the one-way valve failure rate is high, must weld again during replacing, and working procedure is quite loaded down with trivial details, pours in down a chimney loss and is difficult for discovering, and misleads hole condition and judges.
Summary of the invention
The utility model provides a kind of removable one-way valve of checking conveniently, being convenient to change in order to remedy the defective of existing technology.
The utility model is realized through following technological scheme:
A kind of removable one-way valve is characterized in that: comprise three way valve, three way valve wherein two logical is liquid inlet pipe and drain pipe; Another is logical to be movably installed with plug, and the liquid inlet pipe internal fixation is installed a supporting frame, and the supporting frame central position is movably installed with the baffle plate newel; Baffle plate newel upper end is connected with baffle plate; Baffle plate newel lower end is provided with adjusting nut, is provided with between supporting frame and the adjusting nut to be enclosed within the outer spring of baffle plate newel, and the liquid inlet pipe inwall is provided with apron block.
The beneficial effect of the utility model is: this removable one-way valve, and simple in structure, economical and practical, be designed with detachable plug, when after the long-time use of one-way valve, blow-by occurring, replacing accessory for convenience detach and repairing, easy to operate, economical and practical.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the structural representation of the removable one-way valve closed condition of the utility model.
Accompanying drawing 2 is the structural representation of the removable one-way valve open mode of the utility model.
Among the figure, 1 plug, 2 baffle plates, 3 apron blocks, 4 baffle plate newels, 5 adjusting nuts, 6 springs, 7 supporting frames, 8 three way valvies, 9 liquid inlet pipes, 10 drain pipes.
Embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This removable one-way valve is characterized in that: comprise three way valve 8, three way valve 8 wherein two logical is liquid inlet pipe 9 and drain pipe 10; Another is logical to be movably installed with plug 1, and liquid inlet pipe 9 internal fixation are installed a supporting frame 7, and supporting frame 7 central positions are movably installed with baffle plate newel 4; Baffle plate newel 4 upper ends are connected with baffle plate 2; Baffle plate newel 4 lower ends are provided with adjusting nut 5, are provided with the spring 6 that is enclosed within outside the baffle plate newel 4 between supporting frame 7 and the adjusting nut 5, and liquid inlet pipe 9 inwalls are provided with apron block 3.
This removable one-way valve; The import and export of liquid inlet pipe 9 and drain pipe 10 can be adopted clip or other movable connection methods; Supporting frame 7 has adopted three direction fixing rods to connect, and when guaranteeing single current valve guard 2 ability centre-locks, has also guaranteed the space that liquid passes through.When liquid gets into, pushing tow one-way valve baffle plate 2, baffle plate 2 is up under the effect of pressure; Open the liquid inlet passage; Spring 6 is compressed, and when no liquid entering or pressure were lower than spring 6 setting pressures in the pipeline, baffle plate 2 was closed under spring 6 reaction forces; Prevent the refluence of liquid, played the effect of one-way flow.Because movable connection is all adopted at each position of one-way valve, after long-time the use,, can carry out dismounting and change or repairing at any time if any damage.Only need unload plug 1 when inspection and replacing, back out small front apron with special spanner and get final product, not need electrogas welding, easy to operate, economical and practical.
