Problems solved by technology

[0003] During the use of existing ball valves, the valve stem drives the opening and closing parts to rotate to control the opening, while the existing use usually only drives the opening and closing parts to reciprocate Rotation, which in turn causes severe wear on one side of the opening and closing parts, affecting its service life

Embodiment 1

[0026] see figure 1 , in Embodiment 1 of the present invention, it is a structural diagram of a two-stage metal hard-sealed ball valve provided by the embodiment of the present invention, including: a valve body 1, a ball 3 and a driving component;

[0027] The ball 3 is arranged inside the valve body 1, and is used to control the on-off of the valve body 1;

[0028] The driving part is arranged on the valve body 1 and is used to drive the ball 3 to rotate in one direction, and the ball 3 can adjust the opening during the rotation.

[0029] Specifically, the sphere 3 is driven to rotate in one direction through the driving component, so that the sphere 3 can rotate in one direction during the switching process, so that the entire sealing surface of the sphere 3 can be in contact with the sealing part inside the valve body 1 during the rotation process, Further avoiding the reciprocating rotation of the sphere 3 during use in the prior art, so that only part of the sealing sur...

Embodiment 2

[0031] see figure 1 The main difference between this embodiment 2 and embodiment 1 is that a sealing valve seat 2 is provided inside the valve body 1, and the ball 3 is rotatably arranged inside the sealing valve seat 2; both ends of the sealing valve seat 2 are sealed by metal The gasket is installed in the installation groove on the valve body 1, and the sealing valve seat 2 is provided for installing the ball 3.

[0032] see Figure 2-3 , as a preferred embodiment of the present invention, the ball 3 is provided with a valve stem 4, in order to realize the one-way transmission of the driving ball 3, so the driving part includes a transmission assembly and a one-way part, and the transmission part and the valve The rod 4 is connected in transmission, and the transmission part is connected with the one-way part.

[0033] As a preferred embodiment of the present invention, the transmission part can be connected with the valve stem 4 through a gear, or can be connected with t...

Abstract

The invention is suitable for the technical field of valve equipment, and provides a two-stage metal hard sealing ball valve. The two-stage metal hard sealing ball valve comprises a valve body, a ball body and a driving component, wherein the ball body is arranged in the valve body and is used for controlling on and off of the valve body; the driving component is arranged on the valve body and used for driving the ball body to rotate unidirectionally; a sealing valve seat is arranged in the valve body, and the ball body is rotationally arranged in the sealing valve seat; and the two ends of the sealing valve seat are installed in installation grooves in the valve body through metal sealing gaskets. According to the two-stage metal hard sealing ball valve provided by the invention, the service life of the valve is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of valve equipment, in particular to a two-stage metal hard-sealed ball valve. Background technique [0002] Ball valve, the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids, among which the hard-sealed V-shaped ball valve has a strong shear force between its V-shaped ball core and the metal valve seat of surfacing welding carbide, and is especially suitable for fibers and tiny solid particles. etc. medium. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. [0003] During the use of the existing ball valve, the opening and closing part is driven by the valve ...
