Abstract
The utility model relates to a coke removing control valve with an outside placed pressure reducing plate, which belongs to hydraulic coke removing devices used in delayed coke removing equipment of the petrol chemical industry and comprises a valve body, a valve core, an upper sleeve barrel and a lower sleeve barrel. A bypass flow pressure reducing hole plate arranged outside the valve body is communicated with a bypass flow outlet on the valve body, a precharge pressure reducing pore plate is arranged outside the body valve, the inlet of the precharge pressure reducing pore plate is communicated with a precharge hole on the lower sleeve, and an outlet is communicated with a gross flow outlet of the valve body. The structure of the utility model reduces the rust of the hole plate, and the other components does not need to be simultaneously disassembled when the replacement is required, so the facility is provided to ensure the normal work of the control valve.
Description
The utility model belongs to hydraulic decoking equipment in the petrochemical industry delayed coking unit, mainly proposes a kind of decompression plate external placed type decoking control valve.
Decoking control valve is applied to petrochemical industry refinery delayed coking unit hydraulic decoking system, in order to the flow direction of control high pressure decoking water.Accompanying drawing 2 is existing control valve structural representation.When spool 6 was in extreme lower position, valve was in the by-pass flow operating mode, and high pressure water, is crossed upper bush 5 cylindrical shell intermediary flow by ports and flowed into by-pass flow pressure reducing orifice 18 through spool 6 from inlet, flows out after reducing pressure.When spool promoted 70-90mm, valve was in the preliminary filling operating mode, and high pressure water is through entering the mouth 14, and the preliminary filling hole 13 of lower sleeve 8 bottoms of flowing through enters preliminary filling pressure reducing orifice 11, and flow out from valve body 7 bottoms and full spout 15 the decompression back, and a part of high pressure water flows out from by-pass flow passage 19.When spool 6 was in the extreme higher position, valve was in the decoking operating mode, and at this moment the by-pass flow mouth ends, and high pressure water is from entering the mouth directly through lower sleeve 8 intermediary decoking water outlets 9, from full spout 15 outflows of valve body lower portion.Present widely used decoking control valve, the problem that exists is that preliminary filling pressure reducing orifice and by-pass flow pressure reducing orifice all are positioned at valve inner, under the high pressure water effect, easy to wear, the corrosion of pressure reducing orifice, cause the change of High-Pressure Water parameter, if will together dismantle together with the equipment on valve top and change pressure reducing orifice, waste time and energy very much.
The purpose of this utility model promptly is to propose a kind of decompression plate external placed type decoking control valve, to overcome the defective that the pressure reducing orifice embedding structure exists.
The technical scheme that the utility model proposes is: control valve comprises valve body, spool and upper and lower sleeve; Drain hole, preliminary filling hole and decoking water outlet have been set on the sleeve; The by-pass flow pressure reducing orifice is arranged on the valve body outside, and is communicated with by-pass flow outlet on the valve body; The preliminary filling pressure reducing orifice is arranged on the valve body outside, and its entrance end is communicated with preliminary filling hole on the lower sleeve, and outlet is communicated with the full spout of valve body.
The utility model is arranged on the valve body outside with by-pass flow pressure reducing orifice and preliminary filling pressure reducing orifice, has reduced the corrosion of orifice plate, simultaneously need not to dismantle other parts when needs are changed, is the assurance control valve works better condition of providing convenience.
Embodiment:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is existing decoking control valve structural representation.
The accompanying drawing that provides is in conjunction with the embodiments further specified its structure:
As shown in Figure 1, control valve comprises valve body 7, spool 6 and upper and lower sleeve 5,8, and drain hole 16 is arranged on the cylindrical shell of upper sleeve 5, and drain hole is communicated with by-pass flow outlet 19, and preliminary filling hole 13 and decoking water outlet 9 are arranged on the lower sleeve portion 8, and they are communicated with full spout 15; By-pass flow pressure reducing orifice 18 is arranged on the valve body outside, and it is communicated with by-pass flow outlet 19 on the valve body, and connects high-order water pot; Preliminary filling pressure reducing orifice 11 is arranged on the valve body outside, and its entrance end 12 is communicated with preliminary filling hole on the lower sleeve 8, and outlet 10 is communicated with the full spout 15 of valve body.
