Abstract
A combined type ball valve designed by the utility model mainly comprises a valve body, a ball body and a switch lever. A round through hole is arranged in the center of the ball body, the valve body is a cylindrical hollow structure, and the ball body is arranged at the central position of the valve body; a seal retaining cover is arranged in the hollow structure at the relative side of the valve body and the ball body, and the center of the seal retaining cover is equipped with a through hole of which the diameter is consistent with the through hole diameter of the ball body; a rectangular groove is arranged at the upper end of the ball body, the switch lever is connected with the rectangular groove on the ball body, and a connecting tube is connected on the two sides of the valve body via locking caps. The combined type ball valve employs the valve body of which the apertures at the two ends are different, so that the installation of the ball body is convenient; meanwhile, by arranging the seal retaining cover at the end of which the aperture is larger, the ball body is limited; the seal retaining cover and the locking caps are both connected with the valve body via screw threads, and the thread directions of both are reverse, so that the seal retaining cover can be prevented from loosing effectively, and the seal effect is not affected.
Description
Technical field
The utility model relates to the ball valve field, especially a kind of combined type ball valve.
Background technique
At present, ball valve is mainly used to cut off, distribute and change the flow direction of medium in pipeline.Ball valve is little with fluid resistance, simple in structure, the sealing surface of spheroid and valve body and medium isolation, passage is smooth smooth, be difficult for deposition medium, and be not only applicable to the general work medium, but also be applicable to the abominable medium of operating conditions, extensive every field such as utilization and oil, chemical industry, generating, and in the daily life.
Existing ball-valve structure is complicated, and difficulty is installed.Under high-pressure situations, use, easily cause between valve body and the spheroid pressure excessive, cause spheroid generation local displacement, affect the sealability of ball valve.And in long-time use, the cooperation tightness between the ball valve all parts descends, and causes ball valve easily to damage.
The model utility content
The purpose of this utility model is to provide a kind of sound construction, the combined type ball valve that usability is good for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the combined type ball valve that the utility model is designed, it mainly comprises valve body, spheroid and switch lever, be provided with manhole in ball centre, described valve body is cylindrical hollow configuration, spheroid is arranged on the valve body neutral position, valve body is consistent with the manhole diameter on the spheroid with respect to the hollow diameters of a side of spheroid, valve body is consistent with the external diameter of spheroid with respect to the hollow diameters of the opposite side of spheroid, and the sealing door is set in the hollow structure of this side, sealing door center is provided with through hole, diameter is consistent with the spheroid through-hole diameter, be provided with rectangle groove in spheroid upper end, described switch lever is connected with rectangle groove on the spheroid, is connected with connecting tube in the valve body both sides by locking cap.This structural feature is, all parts is by combination, and sound construction is easy for installation, and applicability is good.
As optimization, described sealing door is provided with outside thread, is provided with internal thread in the valve body, and sealing door and valve body are threaded connection, and are provided with internal thread in two locking caps, and the valve body two ends are provided with outside thread, and valve body and locking cap are threaded connection.Above-mentioned parts adopt and are threaded, and more firm, installing/dismounting is more simple and convenient.
Further optimize, the outside thread direction at valve body two ends is consistent, the internal thread opposite direction in the outside thread at valve body two ends and the valve body.This structure processing technology is simple, and linkage structure is firm, is difficult for loosening.
Further optimize, above-mentioned each internal thread and outside thread all adopt sawtooth thread, make to seal closelyr between the parts, and intensity is high, and soundness is good.
The resulting combined type ball valve of the utility model adopts valve body two ends bore different, makes things convenient for the installation of spheroid, is provided with the sealing door at the larger end of bore simultaneously, gives spheroid spacing.The sealing door is connected with valve body by screw thread, and locking cap is connected with valve body by screw thread equally, and both hand of spirals are opposite, can effectively avoid sealing door and occur to become flexible, and affects the phenomenon of sealing effect.In addition, each screw thread all adopts sawtooth thread, make between all parts cooperate more firm, good seal performance.Be connected with spheroid by rectangle groove at switch lever, connect conveniently, sound construction is reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
