Problems solved by technology

[0007] The purpose of the present invention is to provide a fully floating ball hard-sealed ball valve, which is used to solve the damage of the sealing surface caused by the non-floating or limited floating between the valve ball and the valve seat when the valve ball is in the open position in the prior art. Leakage, fracture of the flat tenon of the valve stem, etc.

Embodiment Construction

[0015] In order to achieve the above object, the present invention provides a technical solution, which will be described below in conjunction with the accompanying drawings:

[0016] This full floating ball hard seal ball valve mainly includes main valve body, auxiliary valve body, main valve seat, auxiliary valve seat, spring, valve ball, adapter shaft, valve stem, stuffing box. The main valve body 01 and the auxiliary valve body 02 are connected by bolts 03 and nuts 04 to form a pressure-bearing shell; the main valve seat 05 is a fixed valve seat, and the sealing surface is a high-hardness alloy, which is fixed on the On the auxiliary valve body 02, the main valve seat 05 and the auxiliary valve body 02 are sealed by a metal plane; the auxiliary valve seat 07 mentioned above is a floating valve seat, and the sealing surface is a high-hardness alloy, which is installed in the seat hole 15 of the main valve body , the spring 08 is arranged between the auxiliary valve seats of...

Abstract

The invention discloses a rigidity seal floating ball valve, and particularly relates to a full-floating ball rigidity seal ball valve. The full-floating ball rigidity seal ball valve mainly comprises a main valve body, a valve ball, a main valve seat, namely a fixed valve seat which is fixed on the valve body, a subsidiary valve seat, namely a floating valve seat which is pushed by a spring, a coupling shaft, a valve rod and a stuffing box. According to the full-floating ball rigidity seal ball valve, when the valve ball is at a full-opening position and a full-closing position or is in an opening-closing process, the valve ball can float in the passage direction, so that the sealing surface of the valve ball and the sealing surface of the fixed valve seat are in a close clinging state all the time; a medium is prevented from entering a space between the sealing surfaces; and pressure between the sealing surfaces are prevented from being overlarge, and the valve rod is prevented from being affected by a bending moment. Therefore, internal leakage and external leakage are avoided, and the service life of the valve is prolonged.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a full-floating hard-sealed ball valve. technical background [0002] There are existing floating ball hard-sealed ball valves, the driving valve stem is directly connected to the valve ball, the connecting part of the valve stem is a flat tenon structure, the valve ball is a tenon-groove structure, and the tenon-groove direction of the valve ball is perpendicular to the flow path of the valve ball. This structure determines that when the valve ball is in the closed position, the valve ball can float freely, but when in the open position, the ball and the valve seat cannot float or the floating is limited, then there will be the following consequences: [0003] There is a gap between the valve ball and the main seal seat, and the medium enters the gap. If the medium is hard particles, it will cause seal damage during the opening and closing process, and the valve will leak. [00...
