方便取样排气的压力表管道
摘要：
本实用新型公开一种方便取样排气的压力表管道，连接在泵上的进液管和出液管，在出液管上设置有压力表，在压力表连接出液管的管道上设置有排空阀，在管道上设置有三通，排空阀与三通的一端连接。采用上述技术方案，本实用新型有以下优点：在泵出口阀门压力表控制阀门后加装三通，在三通上连接一排空阀，在取样和排空时不用拆掉压力表，可以打开排空阀，方便取样、方便排空。安全、省时、省力，大幅降低了成本。
摘要（英）：

The utility model discloses a pressure gauge pipeline convenient for sampling and emptying which comprises a liquid intake pipe and a liquid outtake pipe which are connected onto a pump, wherein a pressure gauge is arranged on the liquid outtake pipe, and an emptying valve is arranged on a pipeline through which the pressure gauge is connected with the liquid outtake pipe; and a three-way joint is arranged on the pipeline, and the emptying valve is connected with one end of the three-way joint. With the technical scheme, the pressure gauge pipeline convenient for sampling and emptying has the following advantages that: the three-way joint is additionally arranged at the back of a control valve of the valve pressure gauge arranged at an outlet of the pump, and the emptying valve is connected onto the three-way joint, so that the pressure gauge does not need to be detached in sampling and emptying, and the emptying valve can be turned on, and thus the sampling and the emptying are convenient. The pressure gauge pipeline convenient for sampling and emptying is safe, time-saving and labor-saving, and the cost is greatly reduced.
