Water quality sampling flexibly-connected locking valve

Abstract

The invention provides a water quality sampling flexibly-jointed locking valve which comprises a water inlet pipe, a water outlet pipe and a ball valve main body connected between the water inlet pipe and the water outlet pipe, a spherical valve core which is arranged in the ball valve main body, and a water sampling plunger valve which is vertically connected with the ball valve main body and arranged between the ball valve main body and the water outlet pipe, wherein a regulating handle is arranged above the ball valve main body, one end of the regulating handle is connected with a ball valve pole which is fixedly connected with the ball valve core, and a sliding locking piece which is mutually and tightly fastened with a locking buckle above the ball valve main body is arranged in the other end of the regulating handle. The water sampling valve adopts a T-shaped connection, a sample can be taken from the splitting cavity of a drainage pipeline and the water sampling can be carried out during a normal water discharging process so as to facilitate the monitoring and processing of the change of the water quality, or the liquid quality of manufacture factories can be dynamically monitored, and the sampling valve is flexibly connected with the nut of a discharge pipe so as to ensure convenient and rapid connection during the equipment maintenance and pipeline change. The regulating handle and the sliding locking piece arranged in the handle ensures that the ball valve core can be conveniently fixed and locked so as to avoid the ball valve closure and ensure safe and reliabledischarge.

Description

technical field [0001] The invention relates to a water quality sampling valve of a water treatment system, in particular to a live joint locking valve for water quality sampling of heating pipelines, boiler pipelines and wine industry pipelines. Background technique [0002] In water treatment systems such as heating pipelines, boiler pipelines, and wine industry pipelines, water quality needs to be sampled and tested. The sampling method is relatively complicated. Usually, multiple pipelines and valve faucets need to be installed in each treatment process. The water quality samples can only be extracted from the mouth, and the accumulated water in the branch pipeline must be drained before extraction, so as to extract the water quality standard currently being treated. If the accumulated water in the bypass pipeline is not drained, the current water quality test results will be negative have a certain impact. CN201765130U proposes a double cut-off discharge sampling valve...

[0002] In water treatment systems such as heating pipelines, boiler pipelines, and wine industry pipelines, water quality needs to be sampled and tested. The sampling method is relatively complicated. Usually, multiple pipelines and valve faucets need to be installed in each treatment process. The water quality samples can only be extracted from the mouth, and the accumulated water in the branch pipeline must be drained before extraction, so as to extract the water quality standard currently being treated. If the accumulated water in the bypass pipeline is not drained, the current water quality test results will be negative have a certain impact

CN201765130U proposes a double cut-off discharge sampling valve, which uses two stop valves and a needle valve two-way connection to realize water sampling during normal discharge. This structure is complex, inconvenient to operate, and there is still residual liquid storage that affects the detection effect and accuracy issues

However, the valve is not allowed to be closed or opened at will during general production operation.
