What are the commonly used valves in industrial enterprises,And the resilient wedge gate value company
The resilient wedge gate values commonly used in industrial enterprises (the valves commonly used in various pipelines in various industrial enterprises) are as follows:
Valves for opening and closing: resilient wedge gate values, ball valves, butterfly valves, stop valves, rotary valves, valves used to open and close pipelines, such valves are called closed-circuit valves.
Adjusting valves: pressure reducing valve, throttle valve, used to adjust the pressure and flow of the medium in the pipe.
Check valve: check valve, used to prevent the medium from flowing back.
Distribution valve: three-way rotary valve, used to change the flow direction of the pipeline and distribute the medium.
Resilient wedge gate values for trapping air traps: traps are used to remove condensate and prevent steam from leaking.
Safety valve: safety valve (overflow valve), used for overpressure safety protection, discharge excess medium, and prevent pressure from exceeding the specified value.
How is the resilient wedge gate value model compilation method and valve logo development?
The resilient wedge gate value model should usually indicate the valve type, drive mode, connection form, structural characteristics, sealing surface material, valve body material, and nominal pressure. The standardization of valve models provides convenience for valve design, selection, distribution and construction management.
The rapid development of science and technology, manifested in the field of resilient wedge gate value technology, has made more and more types of valves and materials, and more and more complicated valve models. Although my country has a unified standard for valve model compilation, it is increasingly unable to meet the needs of valve technology development. At present, resilient wedge gate value manufacturers generally adopt a unified numbering method: where a unified numbering method cannot be used, each valve manufacturer has developed a numbering method according to its own needs.
The name of the resilient wedge gate value is named according to the transmission mode, connection form, structure form, lining material and type, but the following contents are omitted in the naming:
1) "Flange" in the connection form.
2) In the structural form: ① "open stem", "elastic", "rigid" and "single gate" of gate valve; ② "straight-through" of stop valve and throttle valve; ③ "floating" and "straight-through" of ball valve Type”; ④“Vertical plate type” of butterfly valve; ⑤“Roof type” of diaphragm valve; ⑥“Packing” and “straight type” of plug valve; ⑦“Straight type” and “single valve type” of check valve; ⑧ "Not closed" of the safety valve.
3) The name of the material in the sealing surface material of the resilient wedge gate value seat.
