A valve sewage diversion device and its use method

Abstract

The invention relates to a sewage discharge diversion device for valves and a method of use thereof, comprising a workbench, a support platform and a collection tank, the workbench is located above the support platform, and a funnel-shaped diversion device is fixed on the bottom of the workbench A collection tank is placed under the support platform, the guide tube runs through the support platform and communicates with the collection tank, a support rod is fixed at the top center of the workbench, and a lever is connected to the top of the support rod in rotation, so The two ends of the lever are respectively fixed with pressing plates. The invention can make the blowdown of a plurality of valves be carried out continuously without interruption, thus improving the working efficiency.

Description

technical field [0001] The invention relates to the technical field of valve sewage discharge, in particular to a valve sewage discharge guide device and a use method thereof. Background technique [0002] Valves are important control components for oil and gas pipeline transportation. In daily maintenance, the valve needs to be drained regularly to remove grease, waste liquid and other impurities accumulated in the valve, so as to protect equipment and pipelines from pollution and corrosion. In addition, valve blowdown is also the main method for valve internal leakage inspection. The main part of the valve blowdown is usually a blowdown nozzle, which is located at the bottom of the valve. When draining, open the drain nozzle and use the pressure drop in the valve cavity to discharge the impurities. [0003] However, when the valve is blowing down, because it depends on the pressure drop to discharge the impurities, the impurities are easy to disperse under the air press...

AI Technical Summary

Problems solved by technology

[0003] However, when the valve is blowing down, because it depends on the pressure drop to discharge the impurities, the impurities are easy to disperse under the air pressure, causing environmental pollution, and it is easy to cause injury to the operator. At the same time, in order to discharge the impurities as completely as possible, the valve on the It needs to wait for a period of time after the sewage nozzle is opened. At this time, the operator only needs to wait without any action, resulting in waste of time and low work efficiency.
