Electric valve manufacturersIntroduce the method of reasonably dealing with the leakage of electric butterfly valve
1: Improve the sealing vegetable grease method; For unused sealing grease valves, consider improving the sealing vegetable grease to improve the sealing characteristics of the valve seat.
2: lifting the filling material method; in order to improve the sealing characteristics of the filling material to the piston rod, the method of lifting the filling material can be adopted. Generally, two-layer and double-layer mixing and filling materials are selected to purely increase the total number. If 3 pieces are increased to 5 pieces, the actual effect is not very obvious.
3: the removal of graphite packing method; widely used tetrafluoro filler, with its operating temperature in the range of -20~200 ℃, when the ambient temperature in the lower, lower limit, the change is larger, the tightness will be significantly decreased, aging fast, short cycle. Soft graphite packing can solve this defect and is strong and durable. Therefore, some factories have changed the tetrafluoro filler into graphite filler, and even the newly bought regulating valves have changed the tetrafluoro filler into graphite filler before reuse. However, the application of graphite packing has a large return difference, and some of them cause jitter at the beginning, so it must be taken into account.
Electric valve manufacturers: What are the advantages and disadvantages of valve electric equipment?
The main shortcomings of the valve electric equipment structure is cumbersome, the average equipment failure rate is higher than the pneumatic actuator, the application of explosion-proof requirements are not too high, the lack of pneumatic valves.
The valve electric equipment is characterized by convenient access to power energy, fast data signal transmission rate, long transmission distance, which is conducive to centralized control system, high sensitivity, convenient coordination with electric adjustment instruments, and simple assembly and wiring.
1. Strong function: full intelligence, proportional type, power switch type, all kinds of information export type.
2, the volume is exquisite: the volume is only equivalent to 35% of the same industry.
3, light cost-effective person: net weight is only equivalent to 30% of the same industry.
4, reliable characteristics: rolling bearing tooth head electrical components and other key components selected imported well-known brands.
5, unique: aluminum alloy casting shell, meticulous and smooth, and can reduce the interference signal.
6, wear resistance: gear input shaft integration special aluminum alloy forging, high strength, good wear resistance.
7. The return difference is very small: the gear input shaft is integrated, the key connection gap is prevented, and the transmission accuracy is high.
8. Safety guarantee: According to 1500V compression test, F-class insulation motor is guaranteed.
9. Simple supporting facilities: it is very simple to choose single-phase power supply and external line, and it can also be used as 380V and DC regulated power supply.
10. Convenient to use: free oil, maintenance-free, moisture-proof and rust-proof treatment, random viewing angle assembly.
11. Protection equipment: bidirectional positioning, overheat protection, overvoltage protection (optional).
12. Various rates: full travel time of 5 seconds, 10 seconds, 15 seconds, 30 seconds, 60 seconds, 100 seconds, etc.
13. Anti-corrosion and anti-rust treatment: the support frame, coupling and screws are all made of stainless steel plates.
14, intelligent CNC machine tools: data setting, data setting value, relatively high accuracy, self-diagnosis, a machine with many functions.
15. Integration: The intelligent control module is relatively highly integrated in the electric equipment itself, and there is no need for an external locator.
