[0005] In view of the deficiencies of the prior art, the utility model provides a flange plate ball valve convenient to installation, solves the problem that the device lacks a caliber flexible adding mechanism, so that the existing device only uses symmetrical welding to connect with external pipelines, and it is difficult to be applicable to unconventional, asymmetrically connected special use environments.

[0006] To achieve the above purpose, the utility model is realized by the following technical scheme: a flange plate ball valve convenient to installation, including valve body and welding end, the one end of valve body is connected with flange, the flange is coaxial with the internal flow passage of valve body, the both ends of flange are all opened the connecting hole along its thickness direction, the connecting bolt is inserted into the connecting hole with clearance fit, the screw rod portion of connecting bolt is inserted into connecting hole and is screwed with connecting nut, the connecting nut and the nut portion of connecting bolt are located on the both sides of flange respectively.

[0007] Preferably, bolt holes are formed on both sides of the flange connection end and the pipe flange connection end, and a bolt is inserted through the two bolt holes on the same side. When in use, the valve body and other pipelines can be installed in unconventional, asymmetrically connected special use environments by means of the flange, connecting bolt and connecting nut, so that the applicability of the application to the installation environment is stronger.

[0008] Preferably, one end of the valve body is threadedly connected with a mounting cylinder, the flange is sleeved outside the mounting cylinder, a limiting ring is fixedly arranged at the end of the mounting cylinder away from the valve body, the limiting ring is located at the side of the flange away from the valve body, and the outer edge diameter of the limiting ring is greater than the inner edge diameter of the flange. The detachable connection of the flange relative to the valve body can be realized, so that the flange is convenient to disassemble and assemble.

[0009] Preferably, the inner edge of the mounting cylinder is a regular hexagon in section. The mounting cylinder is convenient to rotate by means of an existing hexagonal wrench, and the operation convenience is improved.

[0010] Beneficial effects

[0011] The utility model provides a flange disc ball valve convenient to install, and has the following beneficial effects compared with the prior art: the utility model discloses a welding end and one end connected with a flange are arranged on one side of the valve body, the flange is coaxial with the internal flow channel of the valve body, connecting holes are arranged in the thickness direction of the two ends of the flange, connecting bolts are arranged in the connecting holes in clearance fit, the screw rod of the connecting bolt passes through the connecting hole and is threadedly sleeved with a connecting nut, and the connecting nut and the nut part of the connecting bolt are located on the two sides of the flange respectively. During use, the valve body and other pipelines can be installed in a very special and asymmetric connection environment by means of the flange, the connecting bolt and the connecting nut, so that the applicability of the utility model to the installation environment is stronger. Meanwhile, the one end of the valve body is threadedly connected with a mounting cylinder, the flange is sleeved outside the mounting cylinder, a limiting ring is fixedly arranged at the end of the mounting cylinder away from the valve body, the limiting ring is located at the side of the flange away from the valve body, and the outer edge diameter of the limiting ring is greater than the inner edge diameter of the flange. The detachable connection of the flange relative to the valve body can be realized, so that the flange is convenient to disassemble and assemble. BRIEF DESCRIPTION OF DRAWINGS
