The static balance valve is a valve with special functions. The special feature of the valve itself is that the function and location are different. In some industries, due to the large pressure difference or flow difference of the medium (all kinds of flowable substances) in various parts of the pipeline or container, in order to reduce or balance the difference, between the corresponding pipelines or containers A valve is installed to adjust the relative balance of the pressure on both sides, or to achieve a balance of flow through the method of shunt, the valve is called a balance valve. 1) Linear flow characteristics, that is, when the pressure difference between the front and rear of the valve remains unchanged, the flow rate and the opening degree are roughly linear; 2) There is a precise opening indication; 3) There is an opening locking device, and non-managers cannot change the opening at will; the table connection can easily display the pressure difference before and after the valve and the flow through the valve. Although the balance valve has many advantages, there are still many problems in its application in the air-conditioning water system. If these problems are not solved well, the characteristics of the balance valve cannot be fully displayed. The function of the balance valve is to adjust the predetermined flow of each distribution point (such as each floor) in the system. Balancing valves are installed at the entrance of each building, which can reasonably distribute the total flow of the heating system.
Overview
SP45 digital lock balance valve is a regulating valve with special function of digital lock. It adopts DC valve body structure and has better equal percentage flow characteristics. It can distribute flow reasonably and effectively solve the problem of heating (air conditioning) system. There is a problem of uneven heating and cooling at room temperature. At the same time, it can accurately adjust the pressure drop and flow to improve the liquid flow state in the pipe network system to achieve the purpose of liquid balance in the pipe network and energy saving.
Working principle
It is a static balance valve (opening degree) by changing the gap between the valve core and the valve seat to change the flow resistance through the valve to achieve the purpose of regulating the flow. Its role is the resistance of the system. According to the proportion of design and calculation, each branch is increased or decreased proportionally at the same time, which still meets the flow demand of partial load under the current climate demand, and plays a role in heat balance.
Performance
1) Excellent adjustment performance;
2) Excellent cut-off function;
3) Display the number of open turns accurate to 1/10 turn;
4) The theoretical flow characteristic curve is an equal percentage (approximate) characteristic. When the valve authority is 30-50%, the actual flow characteristic is linear;
5) With the opening lock function, non-property management personnel cannot change the setting state;
6) It can easily and effectively adjust the pressure and flow, and the supporting intelligent instrument can easily display the working pressure difference and flow, and guide and record the balance adjustment plan;
7) PTFE sealing, reliable sealing performance and long service life;
8) According to its opening percentage and the pressure difference before and after the valve, the flow through the valve can be calculated;
9) Internal components are made of stainless steel and copper alloy, with strong anti-corrosion performance;
10) There is no need to reserve operating space for the inner lift valve stem;
