Easy-to-open high-pressure hydraulic ball valve

Abstract

The invention discloses an easy-to-open high-pressure hydraulic ball valve. The easy-to-open high-pressure hydraulic ball valve comprises a first valve seat. A first pipeline is arranged on each of two sides of the first valve seat, a second valve seat is arranged at one end of one of the first pipelines, second pipelines are symmetrically arranged on two sides of the second valve seat, and the second pipelines and the first pipelines are connected through flanges. A fixing seat sleeves the portion, away from the first valve seat, of each second pipeline. A first adjusting mechanism is arranged in each fixing seat. A flat washer is arranged in the middle of the top end of each of the first valve and the second valve. A first pull handle located at the top end of each flat washer and a first inlet located on one side of the corresponding first pull handle are arranged above the first valve seat. An outlet is aranged at the top end of one side, away from the second valve seat, of the first valve seat. The easy-to-open high-pressure hydraulic ball valve has the advantages that when the valve has a failure, fluids are cut off effectively through the first adjusting mechanisms, so thatcirculation of the fluids is avoided, the performance of devices is improved, and resource waste caused by fluid leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an easy-to-open high-pressure hydraulic ball valve. Background technique [0002] The ball valve is an opening and closing part, which 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, where there is a strong shear force between the V-shaped ball core of the hard-sealed V-shaped ball valve and the metal valve seat of hard-facing hard alloy. 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. [0003] According to the patent application number: CN201710999808.9, it relates to the field of control valves, in particular to an easy-to-open high-pressure hydraulic ball valve, which includes a ball valve and a pre-pressure relief mechanism. The ball ...

Problems solved by technology

[0004] However, when the above-mentioned existing ball valve is in use and the ball valve is closed, due to the high pressure inside the ball valve, it is difficult to rotate the handle to make the ball turn from the closed state to the conductive state, so a larger The torque force not only increases the turning force of the staff to turn the handle, but also turns the handle with high strength, causing the tie rod to break, resulting in damage to the valve and serious waste of funds. At the same time, the internal pressure of the fluid cannot be changed, making it difficult to open the valve. It is impossible to perform emergency operation to control the on-off of the valve, resulting in serious fluid leakage
