Flow valve

Technical Field

The utility model belongs to the valve field relates to a flow valve.

Background

In daily life, flow monitoring is needed in pipelines, in the past, an orifice plate device for connecting a flow meter to detect flow and a ball valve for adjusting and locking flow through a valve core opening angle are respectively connected in series on a shunt pipe, and meanwhile, a safety valve for safety pressure relief is required to be additionally installed. Because the valves and the pipes are more, the construction of the pipeline is time-consuming and labor-consuming, and the material and installation cost is high.

In order to solve the above problems, inventions have been made, such as the following: 201821347488.5A flowmeter valve is provided with a transparent flow tube between a water inlet and a valve ball, a scale for displaying the flow is provided on the flow tube, a notch corresponding to the scale position is provided on the valve body for displaying the scale, a flow core is provided in the flow tube, the flow core is cylindrical and is close to the water inlet, the flow core offsets the water flow impact force by the elasticity of a spring, and the flow flux in the valve is known by reading the position of the flow core on the scale. The too big problem of volume after the flowmeter has been connected to current valve has been solved in design like this. However, many problems exist, for example, the valve can only measure the flow in one pipeline, a plurality of valves need to be installed in the face of a plurality of pipelines, the cost is increased suddenly, the practicability is not high, a plurality of pipelines need to be used in daily life, when the pipelines do not need to measure the flow, the valves can only be connected from other branches, the flexibility is poor, and the requirements of people cannot be met far away. Therefore, solving the existing problems makes the matters to be solved not easy at present.

Disclosure of Invention

The utility model aims at the above-mentioned problem that prior art exists, provide a flow valve. The technical problem solved by the flow valve is how to enhance the practicability of the flow valve.

The purpose of the utility model can be realized by the following technical proposal:
