Abstract
The utility model discloses a double-sheet ball valve which comprises a valve body (5) and a valve seat (2); a ball (3) which is connected with a valve rod (8) is arranged on the valve seat (2); the outer end of the valve rod (8) is connected with a handle; the valve body (5) is of an asymmetric integrated structure; a step is arranged in one side, provided with a long flow path, of the valve body (5); the side, which is not provided with a long flow path, of the valve body (5) is in screw connection with a valve cover (1) with a long flow path; and a through hole of the valve body (3) is coaxial with the flow paths of the valve cover (1) and the valve body (5) when being completely opened. The double-sheet ball valve has the beneficial effects of being reasonable in structural design, small in resistance, good in sealing property and convenient in maintenance, and greatly prolonging the service life.
Description
Technical field
The utility model relates to valve, is specifically related to a kind of two-piece type ball valve.
Background technique
The conventional ball valve complex structural designs, volume is big, and demolition and maintenance are inconvenient; Because structural design is unreasonable, adopt curved channel, resistance is big, causes the corrosion of valve sealing face easily, and poor sealing performance has influenced working life of valve.
Summary of the invention
To the shortcoming of existing ball valve, the utility model provides a kind of novel two-piece type ball valve.
To achieve these goals, the measure taked of the utility model:
A kind of two-piece type ball valve comprises valve body and valve seat, and spheroid is housed on the valve seat; Spheroid is connected with valve rod; The outer end of valve rod is connected with handle, and valve body adopts the asymmetric overall structure, and the side inside that valve body is provided with long runner is provided with step; The side that valve body is not established long runner is spirally connected with the valve gap that is provided with long runner, and the through hole of spheroid is coaxial with the runner of valve gap and valve body under the complete opening state.
The beneficial effect of the utility model: reasonable in design, resistance is little, and good seal performance is easy to maintenance, and prolong working life greatly.
Description of drawings
Fig. 1, the structural representation of the utility model.
Embodiment
A kind of two-piece type ball valve comprises valve body 5 and valve seat 2, and spheroid 3 is housed on the valve seat 2; Spheroid 3 is connected with valve rod 8, and the outer end of valve rod 8 is connected with handle, and valve body 5 adopts the asymmetric overall structure; The one of which side is provided with long runner, and opposite side is not provided with long runner, and the side inside that valve body 5 is provided with long runner is provided with step; Be used to locate valve seat 2, the side that valve body 5 is not established long runner is spirally connected with the valve gap 1 that is provided with long runner, dismantles easy to maintenance; The through hole of spheroid 3 is coaxial with the runner of valve gap 1 and valve body 5 under the complete opening state, and resistance is little.The beneficial effect of the utility model: reasonable in design, resistance is little, and good seal performance is easy to maintenance, and prolong working life greatly.
Those skilled in the art's simple change and replacement all are within the protection domain of the utility model in related domain.
