Balance valve is a kind of valve with special function. The special feature of the valve itself lies in its use function and all the differences between the field. In a certain
In some industries, due to the large pressure difference or flow of media (all kinds of flowable substances) in various parts of pipes or containers
To reduce or balance the difference, install valves between corresponding pipes or vessels to adjust the pressure on both sides
Balance, or through the method of shunt to achieve flow balance, the valve is called balance valve.
Static balance valve is also called balance valve, manual balance valve, digital lock balance valve, double position regulating valve, etc. it changes the valve core
The clearance (opening) with the valve seat, to change the flow resistance through the valve to achieve the purpose of regulating the flow, the object of action is
The resistance of the system can balance and distribute the new water volume according to the proportion calculated in the design, and increase or decrease each branch in proportion at the same time.
It can meet the flow demand of partial load under the current climate demand and play the role of heat balance. Dynamic balance valve is divided into dynamic flow
Balance valve, dynamic differential pressure balance valve, self operated differential pressure control valve, etc. Dynamic flow balancing valve also known as: self operated flow control
The system valve, self balancing valve, constant flow valve, automatic balancing valve, etc. are automatically changed according to the system working condition (differential pressure)
In the range of pressure difference, the flow through can be controlled to keep a constant value, that is, the pressure difference before and after the valve
When the pressure is increased, the flow can be kept unchanged by the automatic closing action of the valve. On the contrary, when the pressure difference is reduced, the valve will automatically
When the pressure difference is less than or greater than the normal working range of the valve, it cannot be lifted after all
For additional head, when the valve is turned to the full open or full close position, the flow is still lower or higher than the set flow and cannot be controlled. Dynamic pressure
Differential balance valve, also known as self operated differential pressure control valve, differential pressure controller, stabilized variable synchronizer, differential pressure balance valve, etc., is used for
The pressure difference is used to adjust the opening of the valve, and the pressure drop of the valve core is used to make up for the change of the pipeline resistance, so as to change the working condition
The principle is that the pressure difference of the controlled system can be controlled to be constant within the flow range,
That is to say, when the pressure difference of the system increases, through the automatic closing action of the valve, it can ensure that the pressure difference of the controlled system increases; otherwise, when the pressure
When the differential pressure is reduced, the valve opens automatically and the differential pressure remains constant. Self operated differential pressure control valve, automatic valve plug within the control range
In the closed state, when the pressure difference at both ends of the valve exceeds the pre-set value, the valve plug will automatically open and adjust the opening under the pressure sensing film, Keep the pressure difference at both ends of the valve relatively constant.
1. Ideal regulation performance;
2. Superior cut-off function;
3. To 1 / 10 turn on status display;
4. The theoretical flow characteristic curve is equal percentage characteristic curve;
5. Type C lock device;
6. Corresponding to each whole turn, there is a flow coefficient determined by factors. In the commissioning, as long as the pressure difference at both ends of the valve is measured, it can be calculated conveniently
Flow out of the valve;
7. Teflon and silica gel seal, reliable sealing performance;
8. Internal components are made of yicr18ni9 or copper alloy, with strong corrosion resistance and long service life;
9. The inner lifting valve rod does not need to reserve operation space.
10. It is a combination valve.
