I. Introduction:

The function of the flow valve is to adjust the flow rate by using the throttle area between the valve core and the valve body and the local resistance it generates when the pressure difference between the inlet and outlet of the valve changes, so as to control the movement speed of the executive element. It maintains a constant flow rate through it, thereby maintaining a constant flow rate of the controlled object (such as a loop, a user, a piece of equipment, etc., the same below) connected in series with it. When the flow valve is used in the pipe network, the flow rate can be directly set according to the design. The valve can automatically eliminate the residual head of the pipeline and the flow deviation caused by pressure fluctuation under the action of water pressure. The flow valve has many names, such as self-operated flow balance valve, constant flow valve, dynamic balance valve, etc. Various types of flow valves have different structures, but their working principles are similar.

II. Structural Features:

The flow valve is scientifically and reasonably designed with a compact structure. The valve core is provided with U-shaped notches, and the flow can be controlled by adjusting the opening of the notches. A gasket is provided at the inlet of the valve to separate the valve body from the valve core. The radial clearance between the gasket and the valve core can be adjusted to ensure the flexibility of the valve core operation, and it can be matched with various types of actuators.

III. Features of the upgraded Yibao valve:

The valve body adopts an integrated casting process, which avoids medium leakage caused by gaps and poor sealing from manual welding. It is made of ductile cast iron with good thickness and long service life. The valve core of the Yibao valve has good smoothness, with a full-circle valve core and full-circle track, which does not deviate and has high precision. The Yibao valve is equipped with a cover plate, which can ensure no dust leakage and thus meet better dust-proof requirements. The wool felt of the Yibao valve can be directly pulled out from the side, which is convenient for maintenance.

IV. Usage and Installation:

After arrival, it should be properly stored, avoid rain, and be placed in a dry place; ② It should be installed according to the water flow direction indicated by the arrow on the valve body, and must not be installed reversely; ③ It can be installed vertically or horizontally on the pipeline; ④ Flow setting method: Use a special wrench to open the protective screw, rotate the valve stem, and adjust the scale line to the corresponding value of the set flow; ⑤ The flow valve does not have a shut-off function, and a separate shut-off valve should be installed as needed.

Application of Flow Valve:

Operating temperature: 120℃, Pressure: 1.6Mpa

Performance Features:

1. The flow can be set according to design or actual requirements, and it can automatically eliminate the pressure difference fluctuation of the system to keep the flow constant.

2. Overcome the uneven heating (or cooling) phenomenon of the system, and improve the quality of heating (or cooling).

3. Completely solve the contradiction of large pressure difference at the near end and small pressure difference at the far end.

4. Reduce the circulating water volume of the system and lower the system resistance.

5. Reduce the design workload, and no need to carry out complicated hydraulic balance calculation for the pipe network.

6. Reduce the difficulty of pipe network adjustment, and simplify the complex pipe network adjustment work into simple flow distribution.

7. Eliminate the flow redistribution work when the heat sources of the multi-heat-source pipe network are switched.

8. The displayed flow values are all randomly calibrated on the test bench, and the flow unit is m³/h
