Technical Field

[0001] The utility model relates to the technical field of measurement and testing, in particular to a combined flow meter with a valve. Background Art

[0002] Flowmeter, also known as flow meter, measures the instantaneous flow rate and cumulative volume of liquid, and can also quantitatively control the liquid. It has the characteristics of high precision, long life, simple operation and maintenance. It is mainly used in industrial production processes, energy measurement, environmental protection engineering, transportation, biotechnology, scientific experiments, marine meteorology, rivers and lakes, etc.

[0003] The flow meter is usually installed on a section of pipe, and then the pipe is combined with the existing pipe for installation. Since the flow meter itself and this section of pipe are heavy, the two pipes need to be aligned during installation, which makes the installation process difficult and increases the workload of the staff. In view of this, we propose a combined flow meter with valve. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a combined flow meter with a valve, which can solve the problem that it is difficult to connect a traditional flow meter and a pipeline with an existing pipeline.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined flow meter with a valve, comprising a first flow pipe and a second flow pipe, a pipe is arranged on the left side of the first flow pipe, the first flow pipe and the outer surface of the pipe are fixedly connected with a connecting ring, the internal thread of the connecting ring on the outer surface of the first flow pipe is connected with a bolt, the left end thread of the bolt extends out of the left side of the connecting ring on the outer surface of the pipe, the connection method of the first flow pipe and the second flow pipe is the same as the above-mentioned connection method, a pipe is also arranged on the right side of the second flow pipe, the connection method of the second flow pipe and the right pipe is also the same as the above-mentioned connection method, the outer surface of the second flow pipe is fixedly connected with a mounting plate, and the left and right side surfaces of the mounting plate extend to the outer surfaces of the left and right side pipes respectively.

[0006] Preferably, a through groove is provided on the left surface of the connecting ring, the through groove extends to the right surface, the through groove coincides with the mounting plate, a flow meter is fixedly connected to the upper surface of the mounting plate, and the lower surface of the flow meter extends into the interior of the second flow pipe.

[0007] Preferably, a hole is formed on an upper surface of one side of the outer surface of the first flow conduit, and a lower side of the hole extends into the interior of the first flow conduit.

[0008] Preferably, a stop valve is provided inside the first flow conduit, a cavity is opened inside the stop valve, the outer surface of the stop valve is extended from one side of the cavity close to the outer surface of the stop valve, a slide groove is opened on the inner wall of the cavity, a connecting rod is slidably connected to the inside of the cavity, a slider is fixedly connected to the outer surface of the connecting rod, and the slider is matched with the slide groove.

[0009] Preferably, the upper end of the connecting rod extends to the upper surface of the mounting plate through the hole, the upper end of the connecting rod is fixedly connected with a knob, the outer surface of the knob is fixedly connected with a locking buckle, the inner wall of the hole is provided with a locking groove, the locking groove is consistent with the locking buckle, and the outer surfaces of the first flow conduit and the second flow conduit are both provided with directional arrows.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] (1) The combined flow meter with a valve is configured such that the first flow pipe and the second flow pipe are connected by a connecting ring and bolts, and then the mounting plate is placed on the outer surface of the pipe. Since the mounting plate is fixedly connected to the first flow pipe and the second flow pipe, when the lower surface of the mounting plate fits the outer surface of the pipe, the first flow pipe and the second flow pipe will be supported by the mounting plate and aligned with the pipe. Then, the first flow pipe and the second flow pipe can be respectively connected to the pipes on both sides by using the connecting ring and bolts. With the above structure, when installing the flow pipe, the staff can quickly fix and align the first flow pipe and the second flow pipe by placing the mounting plate on the outer surface of the pipe, which reduces the staff's workload and greatly increases the staff's work efficiency.

[0012] (2) The combined flow meter with a valve determines the installation direction by pointing to an arrow. When the flow meter needs to be maintained or repaired, the knob is pulled out by turning it. When the knob is pulled out, it will synchronously drive the connecting rod and the slider to slide inside the cavity and the slide groove respectively. When the knob is pulled out, it will synchronously drive the locking buckle to disengage from the locking groove. At this time, rotating the knob will synchronously drive the connecting rod and the slider to rotate, thereby synchronously driving the stop valve to rotate, so that the stop valve is matched with the inner wall of the first flow pipe, thereby cutting off the water flow. After the stop valve is matched with the inner wall of the first flow pipe, the knob is moved downward. The movement of the knob synchronously drives the locking buckle to enter the interior of the locking groove again. Through the above structure, when the flow meter needs to be maintained or repaired, there is no need to move to a distant place to close the valve to restrict the passage of water flow, so that the staff can maintain or repair the flow meter more conveniently, which improves the work efficiency of the staff and reduces the work intensity of the staff.
