How to choose Programmable Switch Butterfly Valve and maintenance knowledge

1. There are problems with the old selection standards for Programmable Switch Butterfly Valve:

The old selection standard for Programmable Switch Butterfly Valve has many shortcomings. The obvious thing is that it does not mention the type of equipment to be drained and the method of draining. The selected programmable switching butterfly valve often does not match the actual load. What is particularly serious is that the thermodynamic disc programmable switching butterfly valve (the basis of the old selection standard) is mistaken for a universal programmable switching butterfly valve, especially by workshop personnel.

The experiment revealed that there are many problems with the old selection criteria for programmable switching butterfly valves:
①The service life of the Programmable Switch Butterfly Valve in the steam main pipe is too short.
②The performance of the Programmable Switch Butterfly Valve has expired and does not match the actual load selection.
③ As a universal and widely used thermodynamic disc Programmable Switch Butterfly Valve, its energy saving effect is poor, and compared with the inverted bucket Programmable Switch Butterfly Valve, its life span is extremely short.
④The action of the bimetallic piece Programmable Switch Butterfly Valve is prone to instability.
2. Selection tips for Programmable Switch Butterfly Valve:
The new and changed "Guide" includes a programmable switching butterfly valve selection table. Selection tips for Programmable Switch Butterfly Valve:
①Inverted bucket Programmable Switch Butterfly Valve:
As the first choice for programmable switching butterfly valves for all process loads and steam main lines, that is, all occasions where steam drainage is required.
② Float thermostatic Programmable Switch Butterfly Valve:
Used for process dewatering, especially in applications where the control load is less than 3.5 kg (50 psig) or where the air content is high and there are problems with installing an inverted bucket Programmable Switch Butterfly Valve.
③Balance pressure Programmable Switch Butterfly Valve:
For use as uncritical heat tracing or heating systems.
④Bimetal thermostatic Programmable Switch Butterfly Valve:
Used for low temperature or frost-proof conditions of heating pipelines or heating systems. This type of programmable switching butterfly valve can utilize the sensible heat in condensate water or prevent product overheating. The valve body is entirely stainless steel.
⑤Thermal power disc Programmable Switch Butterfly Valve:
It can be used as a replacement for the inverted bucket Programmable Switch Butterfly Valve for limited use on steam mains and tracing pipes with pressures up to 17 kg, or as a product replacement for higher steams, as long as previous experience has proven its performance. pressure.
⑥In situations where heat requirements are not high, replacing the thermodynamic disk programmable switching butterfly valve with a thermostatic programmable switching butterfly valve will improve the energy saving effect and ensure the service life at the same time.
⑦ Mechanical programmable switching butterfly valves can ensure that the steam does not contain condensate no matter when the condensate load is large or small, while thermostatic programmable switching butterfly valves tend to accumulate condensate when the load increases.
