Embodiment

[0023] combined with Figure 1-5 , this embodiment provides a two-piece hard-sealed floating ball valve, including a valve body 1, a valve cover 2, a ball 3 and a valve stem 4, etc., wherein the valve body 1 and the valve cover 2 are obtained by forging process, avoiding the traditional There are defects such as bubbles in the casting. Secondly, in this embodiment, the valve body 1 and the valve cover 2 are arranged horizontally, that is, the valve cover 2 is provided on one side of the valve body 1, and the valve cover 2 faces the side wall of the valve body 1 and the valve body. The side wall of the body 1 facing the valve cover 2 is a vertical wall, and the adjacent ends of the two are connected by a connecting bolt group 5. Secondly, in order to effectively seal the gap between the two, in this embodiment, the valve body 1 An octagonal gasket 37 is also provided between the valve cover 2, and a half-embedded groove is respectively provided on the side wall of the valve bod...

Abstract

The invention discloses a two-piece type hard sealing floating ball valve, and relates to a clamp, the two-piece type hard sealing floating ball valve comprises a valve body, a valve cover, a ball body and a valve rod, the valve body and the valve cover are both obtained through a forging process, the valve cover is arranged on one side of the valve body, and the valve body and the valve cover are connected through a connecting bolt set; a cylindrical limiting block is arranged on one side of the valve cover, a first valve seat is embedded in the cylindrical limiting block, and a mounting space, a second cylindrical space and a second medium channel are sequentially formed in the valve body; the cylindrical limiting block is inserted into the mounting space and is sealed through a sealing device, a second valve seat is arranged in the second cylindrical space, and a multi-sealing assembly is arranged between the second valve seat and the second cylindrical space; the ball body is arranged between the first valve seat and the second valve seat, the top of the ball body is connected with a valve rod, and the top of the valve rod penetrates through the valve body and then is connected with a sealing driving device; medium leakage can be effectively prevented, and the sealing performance of equipment can be effectively improved.

Description

technical field [0001] The invention relates to a valve, in particular to a ball valve. Background technique [0002] Due to the presence of fine catalyst particles and dust in the hydrogenation unit, the catalyst particles and dust enter between the valve sealing surfaces during the opening and closing of the valve, resulting in valve leakage and improper switching. At present, the gate valves and globe valves used in hydrogenation units in the market always leak and do not operate properly. [0003] Therefore, it is urgent to provide a valve with good sealing effect. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a two-piece hard-sealed floating ball valve to solve the technical problem of poor sealing effect of the valve in the prior art. [0005] The present invention is achieved through the following technical solutions: [0006] A two-piece hard-sealed floating ball valve include...
