Abstract

The invention discloses an XBL pipeline ball valve which is characterized by comprising a ball valve body. The ball valve body is mainly formed by a ball body, a middle valve body and a valve rod; a valve left body structure and a valve right body structure are respectively arranged on two sides of the ball body; an opening support seat is arranged on each of the valve left body structure and thevalve right body structure; a seal valve seat is arranged in each opening support seat; an opening press tongue is tightly pressed and fixed to the top end of each seal valve seat; a slope seal face is processed at the top end of each opening press tongue; a smooth support plate is arranged on the bottom part of the ball body; a pressing sleeve, an O-shaped filler, a neck filler tank and an O-shaped ring are sequentially arranged on the periphery of the valve rod from top to bottom; and a thrust washer is arranged between the neck filler tank and the valve rod. The XBL pipeline ball valve provided by the invention has the characteristics of simple structure, long service life, good sealing effect, difficulty in deformation and the like.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to an XBL pipeline ball valve. Background technique [0002] The existing floating ball valve has the following defects: [0003] In the existing floating ball valve, the left and right supporting seats are processed at the junction of the inner cavity of the valve body and the flow channel mouth, and the sealing valve seat is placed. The valve seat is movable and can be removed. Generally, PTFE and other relatively hard and strong materials are used as the sealing ring, but it lacks elasticity. There is no support at the bottom of the ball of the original floating ball valve, and the diameter is slightly larger due to the weight of the ball. Gradually cause the sphere to sink and the seal is not tight. [0004] For the existing floating ball valve seat, in order to avoid the friction generated by the spherical surface from scraping or deforming the valve seat, the valve seat ...
