Abstract
The utility model discloses a multi-nozzle steam pressure matcher which comprises a pressure matcher casing, a high-pressure steam chamber, an outlet and an ejector arranged between high-pressure steam chamber and the outlet. The ejector comprises a low-pressure steam chamber, nozzles, valve rods, a pressure expanding section and a mixing chamber connected with the low-pressure steam chamber and the pressure expanding section. One end of each nozzle is connected with the high-pressure steam chamber, and the other end of each nozzle is connected with the mixing chamber. One end of each valve rod is inserted into a corresponding nozzle, and the other ends of the valve rods penetrate the high-pressure steam chamber to be fixed with a carrying rod through bolts. The carrying rod is fixed with a lifting rod through a bolt, and the lifting rod is connected with an electric actuating mechanism on the outside of the casing. By means of the multi-nozzle steam pressure matcher, heat energy use rate of a steam power system is increased, and the structure is simple. The valve rod is fixed with the carrying rod through a bolt so as to facilitate replacing and maintaining of the valve rod.
Description
Technical field
The utility model discloses a kind of steam pressure matching device having multi-nozzles.
Background technique
Heat supply steam turbine is industrial a kind of machinery commonly used, usually occurs that in the use of heat supply steam turbine supply gas pressure, lower than working pressure, can not meet the needs of heating system, and this just needs a kind of pressure matcher for steam heating system.The pressure regulating equipment of existing steam heating system adopts the single nozzle pressure matcher more, the actual use traffic of single nozzle pressure matcher is during lower than design discharge, and the low pressure steam amount of injection obviously descends, poor to variable working condition adaptability, namely Efficiency Decreasing, cause the waste of the energy.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of energy utilization rate steam pressure matching device having multi-nozzles high, simple in structure, easy to use.
For achieving the above object, the technical solution of the utility model is: a kind of steam pressure matching device having multi-nozzles, comprise the pressure matcher housing, the high pressure steam chamber, outlet and the sparger between high compressed steam chamber and outlet, described sparger comprises low pressure steam chest, nozzle, valve rod, diffuser and the mixing chamber be connected with diffuser with low pressure steam chest respectively, one end of described nozzle is connected with the high compressed steam chamber, the other end is connected with mixing chamber, one end of described valve rod inserts nozzle, the other end of valve rod is bolted through high compressed steam chamber and shadoof, described shadoof and lifting arm are bolted, the lifting arm electric actuator outer with housing is connected.
Described nozzle is at least two.
The beneficial effects of the utility model are: valve rod and shadoof are bolted, and are convenient to replacing, the maintenance of valve rod; Multiinjector arranges, and can adapt to variable working condition, opens a nozzle when small flow, opens two nozzles or three nozzles during large flow, improves energy utilization rate.
The accompanying drawing explanation,
Fig. 1 is structural representation of the present utility model.
In figure: pressure matcher housing 1, high compressed steam chamber 2, export 3, sparger 4, low-pressure steam chamber 41, nozzle 42, valve rod 43, diffuser 44, mixing chamber 45, shadoof 46, lifting arm 47, electric actuator 5, high pressure steam import 21, low pressure steam import 411.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of steam pressure matching device having multi-nozzles, comprise pressure matcher housing 1, high pressure steam chamber 2, outlet 3 and be arranged on high compressed steam chamber 2 and export the sparger 4 between 3, described sparger 4 comprises low pressure steam chest 41, nozzle 42, valve rod 43, diffuser 44 and the mixing chamber 45 be connected with diffuser 44 with low pressure steam chest 41 respectively, described nozzle 42 1 ends are connected with high compressed steam chamber 2, the other end of nozzle 42 is connected with mixing chamber 45, described valve rod 43 1 ends insert nozzle 42, the other end of valve rod 43 is bolted through high compressed steam chamber 41 and shadoof 46, described shadoof 46 is bolted with lifting arm 47, lifting arm 47 electric actuator 5 outer with housing is connected.
Described nozzle 42 is at least two.
The utility model working principle is: pressurized gas enter high compressed steam chamber 2 from high pressure steam import 21, electric actuator 5 pulls lifting arm 47, lifting arm 47 drives shadoof 46 and rises, valve rod 43 in sparger 4, under the lifting of shadoof 46, is extracted out from nozzle 42, after nozzle 42 is opened, pressurized gas enter mixing chamber 45 by high compressed steam chamber 2, under suction function, low-pressure gas also enters mixing chamber 45 by low pressure steam import 411, and mixed gas enters outlet 3 through diffuser 44.
