I. Introduction:

The function of a flow valve is to adjust the flow rate by utilizing the throttle area between the valve core and the valve body, as well as the local resistance it generates, under varying pressure differences at the inlet and outlet of the valve, thereby controlling the movement speed of the executive component. It maintains a constant flow rate through itself, thus keeping the flow rate of the controlled object connected in series with it (such as a loop, a user, a piece of equipment, etc., the same below) constant. When a flow valve is applied in a pipe network, the flow rate can be directly set according to the design, and the valve can automatically eliminate the residual pressure head of the pipeline and the flow deviation caused by pressure fluctuations under the action of water pressure. Flow valves have many names, such as self-operated flow balance valves, constant flow valves, dynamic balance valves, 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 a U-shaped slot, and the flow rate can be controlled by adjusting the opening of the slot. A gasket is provided at the inlet of the valve body 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 equipped 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 a 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 can be directly抽出 from the side of the Yibao valve, which is convenient for maintenance.

IV. Use 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 rate setting method: Use a special wrench to open the protection screw, rotate the valve stem, and adjust the scale line to the corresponding value of the set flow rate; ⑤ The flow valve does not have a shut-off function, and a separate shut-off valve should be provided as needed.

Application of Flow Valve:

Operating temperature: 120℃, Pressure: 1.6Mpa

Performance Features:

1. Can set the flow rate according to design or actual requirements, and can automatically eliminate pressure difference fluctuations in the system to keep the flow rate constant.

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

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

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

7. Eliminate the flow redistribution work when switching heat sources in multi-heat-source pipe networks.

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