Abstract
The utility model relates to a valve, in particular to a pressure and temperature reducing valve, which comprises a valve body, an inlet pipe formed on one side of the valve body, a valve cover located at the top of the valve body and a valve rod penetrating through the valve cover and being inserted in a cavity of the valve body. The bottom of the valve rod is connected with a valve clack, and a throttling ring is arranged on the periphery of the valve clack so as to enable the valve clack to be enveloped in the throttling ring totally. The pressure and temperature reducing valve is characterized by further comprising an outlet pipe located at the bottom of the valve body. A cavity of the output pipe is communicated with the cavity of the valve body, a large cover and a small cover located in the large cover are arranged at the bottom of the valve body, the large cover and the small cover are located in the cavity of the outlet pipe, the outer surface of the output pipe is connected with a sprayer through an elbow pipe, and an atomizing nozzle acted on the cavity of the outlet pipe through straight pipe connection is arranged on the surface of the elbow pipe. Compared with the prior art, the pressure and temperature reducing valve can be used as a regulating valve and a shut-off valve and has multistage pressure reducing functions. Simultaneously, a temperature reducing medium which is atomized through the nozzle has good and effective temperature reducing effects on high-temperature steam.
Description
Technical field
The utility model relates to a kind of valve, a kind of specifically steam converter valve.
Background technique
Present domestic majority steam converter valve, its shower nozzle generally is located at the inside of valve body, but this structure will be difficult to satisfy for the operating mode that requirements at the higher level are arranged.For this reason, in view of reducing cost and obtain more excellent pressure and temperature reducing effect, but we have developed a kind of novel valve that external and double as modulating valve and shut-off valve use with shower nozzle.
Summary of the invention
The utility model has overcome the deficiency of existing technology, and a kind of steam converter valve is provided.
To achieve these goals, the utility model has designed a kind of steam converter valve, comprises valve body; And, also comprise the valve gap that is positioned at the valve body top, and run through valve gap and insert the valve rod of body cavity at the inlet tube that valve body one side forms; Stem bottom connects flap, and is provided with throttle in the flap periphery flap is shrouded interior fully, it is characterized in that: also comprise an outer pipe that is positioned at the valve body bottom; The inner chamber of outer pipe and the intracavity inter-connection of valve body; The valve body bottom also is provided with greatly to be shrouded, and is positioned at shrouding for a short time of shrouding greatly, shrouds and shroud for a short time the inner chamber that is positioned at outer pipe greatly; The outer surface of outer pipe connects shower nozzle through bend pipe, and the surface of bend pipe is provided with the atomizer nozzle of straight tube interconnect function in the outer pipe inner chamber.
The utility model is compared with existing technology, can doublely do modulating valve and shut-off valve and use, and have the multi-step pressure reduction function.Simultaneously, can reach more excellent, more effective temperature lowering effect to high-temperature vapor through the desuperheating agent after the nozzle atomization.
Description of drawings
Fig. 1 is the structural representation of the utility model valve body.
Referring to Fig. 1,1 is valve body; 2 is outer pipe; 3 for shrouding greatly; 4 for shroud for a short time; 5 is bend pipe; 6 is shower nozzle; 7 is straight tube; 8 is inlet tube; 9 is valve gap; 10 is valve rod; 11 is flap; 12 is throttle; 13 is atomizer nozzle.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1; The utility model comprises valve body 1; And, also comprise the valve gap 9 that is positioned at valve body 1 top, and run through valve gap 9 and insert the valve rod 10 of valve body 1 inner chamber at the steam inlet 8 that valve body 1 one sides form; Valve rod 10 bottoms connect flap 11, and are provided with throttle 12 in flap 11 peripheries flap 11 is shrouded interior fully.Also comprise an outer pipe 2 that is positioned at valve body 1 bottom, the inner chamber of outer pipe 2 and the intracavity inter-connection of valve body, valve body 1 bottom also is provided with shrouds 3 greatly, and be positioned at shroud greatly 3 shroud 4 for a short time, shroud greatly 3 with shroud for a short time 4 be built in outer pipe 2 inner chamber.The outer surface of outer pipe 2 connects shower nozzle 6 through bend pipe 5, and the surface of bend pipe 5 is provided with the atomizer nozzle 13 of straight tube 7 interconnect functions in outer pipe 2 inner chambers.
High-temperature vapor flows into inlet tube 8; After the decompression of throttle 12 one-levels, get in the valve body 1, after flap 11 sealing surface second depressurized, get in the cavity of resorption of valve body 1, shroud 4 three grades of decompressions more respectively through for a short time; And the inner chamber that shrouds 3 level Four decompression back inflow outer pipe 2 greatly; Final desuperheating agent flows into through shower nozzle 6, and after atomizer nozzle 13 atomizings, spurts in the outer pipe 2, thereby reaches the effect to the high-temperature vapor desuperheat.
Compare with existing technology, this steam converter valve can doublely make modulating valve and shut-off valve is used, and has the multi-step pressure reduction function, certainly will have better pressure-reducing function.Simultaneously, can reach more excellent, more effective temperature lowering effect to high-temperature vapor through the desuperheating agent after the nozzle atomization.
