Abstract

The invention relates to a high-temperature and abrasion resistant ball valve of a linkage two-position ball. The high-temperature and abrasion resistant ball valve comprises a valve body, a valve base, a butterfly spring, ball bodies, valve rods and a valve cover, wherein the valve body comprises a left valve body, a middle valve body and a right valve body; two cavities are formed in the middle valve body; the middles of the two cavities are penetrated through, and are provided with two ball bodies; the two ball bodies are provided with two valve rods; oil through holes in the two ball bodies are arranged in parallel; the two valve rods are connected in transmission through a synchronous transmission mechanism; and a control mechanism for operating the rotation of the ball bodies is arranged at the end of one of the two valve rods. In the structure, the two ball bodies synchronously rotate; and meanwhile, a valve channel is opened or closed. When the sealing of one cavity is invalid, the other cavity can be still sealed, so that the higher safety is achieved; and the high-temperature and abrasion resistant ball valve of the linkage two-position ball is specifically suitable for dangerous pipes or environments with toxic liquid and gas.

Description

technical field [0001] The invention relates to a ball valve, in particular to a high-temperature and wear-resistant ball valve with a linkage two-position ball. Background technique [0002] Ball valves are widely used in various industries such as power plants, power stations, petrochemicals, etc., to cut off, distribute and change the flow direction of the medium. When operating, manual or mechanical operations only need to rotate 90 degrees and a small rotational torque. Close tightly. A general ball valve includes a valve body, a valve seat, and a sphere, and a butterfly spring is arranged between the valve body and the valve seat. The sphere in the valve body, the upper shaft that rotates with the main valve body, the gland that is connected with the main valve body and restricts the axial position of the upper shaft, and the lower shaft that is connected with the main valve body, and the upper shaft is fixedly connected with the upper end of the sphere, The lower en...
