Description
Technical Field
The utility model relates to a spin valve especially relates to a butt welding spin valve with sweep function.
Background
The existing rotary ball valve consists of a valve body, a pressing ring, a valve seat, a valve clack, an upper valve rod, a lower valve rod, an actuating mechanism and other components, wherein the pressing ring is connected to the valve body, and the valve seat is positioned between the valve body and the pressing ring. The diameter of the pressing ring of the valve is larger than that of the valve seat, the processing complexity is increased, the pressing ring is fixed on the valve body through the bolt, when a medium flows to the valve seat from the valve clack, all pressure acts on the screw rod, and the valve fails after the screw rod is damaged. Secondly, when the valve passes through solid particles, dust or smoke media, the solid particles in the media are attached to the sealing surface of the valve clack, and the valve clack is easy to wear after long-term use, so that the leakage of the valve is caused, and the service life of the valve is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a butt welding ball-cock assembly with function of sweeping to overcome the above-mentioned not enough that prior art exists, improved the structural strength of disk seat.
The utility model aims at realizing through the following structure, it includes: the valve body is connected with the pressing ring, the valve cavity is formed in the valve body, the valve seat and the valve clack are arranged in the valve cavity, the upper portion of the valve clack is connected with the upper valve rod, the lower portion of the valve clack is connected with the lower valve rod, the valve seat is connected with the pressing ring, the valve seat and the pressing ring are located on two sides of the valve body, and a valve seat sealing ring is arranged between.
The valve body is provided with a blowing port, the blowing port is provided with a spray head, and the blowing and sucking port is communicated with the valve cavity.
The sprayer comprises a hemispherical sprayer body, and through holes are uniformly distributed on the sprayer body.
And a floating spring is arranged between the valve seat and the valve body.
A sealing ring and a bearing are arranged between the upper valve rod and the valve body; or a sealing ring and a bearing are arranged between the lower valve rod and the valve body; or a sealing ring and a bearing are arranged between the upper valve rod and the valve body, and a sealing ring and a bearing are arranged between the lower valve rod and the valve body.
The purging port is connected with the joint.
The utility model discloses a disk seat and clamping ring are located the both sides of valve body, and when the medium flowed to the disk seat from the valve clack, medium pressure on the disk seat acted on the valve body, had improved disk seat compressive capacity. Secondly, the valve body is provided with a purging opening and a spray head, high-pressure liquid or gas is introduced through the purging opening, so that the valve clack and impurities in the valve cavity can be effectively removed, the abrasion of the valve clack is reduced, and the service life of the valve is effectively prolonged. And thirdly, a floating spring is arranged between the valve seat and the valve body, so that the valve seat and the valve clack float along the moving direction of the medium, thereby realizing two-way sealing and improving the sealing effect. And fourthly, sealing rings are arranged between the upper valve rod, the lower valve rod and the valve seat, so that a medium is further prevented from entering between the upper valve rod, the lower valve rod and the valve seat and in a bearing, the abrasion of the valve rod and the bearing is effectively reduced, and the service life of the valve is prolonged.
