Technical Field
The utility model relates to a temperature and pressure reducing device, in particular to a steam mixing temperature and pressure reducing water nozzle.
Background
In industrial production, high-temperature and high-pressure steam is subjected to temperature and pressure regulation by a temperature and pressure reducing device, for example, a spring spray head is used for atomizing reduced-temperature water and then mixing the atomized reduced-temperature water with the steam for temperature reduction. But current atomizer is lower to the utilization ratio of desuperheating water, leads to having ponding easily in the desuperheating water pipeline, and ponding can arouse the desuperheating water pipeline to take place resonance and cause the damage, and the desuperheating water is controlled by water route adjusting valve simultaneously, and the desuperheating water utilization ratio is low excessively still can influence the desuperheating effect, causes the cooperation error of water route adjusting valve and spring nozzle too big, still can not drop steam temperature to the design value when desuperheating water maximum flow.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the deficiencies in the background art and providing a steam mixing temperature-reducing water spray head which has the characteristics of high temperature-reducing water utilization rate and good temperature-reducing effect.
The technical scheme of the utility model is that:
steam mixes desuperheating water shower nozzle, its characterized in that: the spray nozzle comprises an inner spray pipe, an outer spray pipe and a spring spray nozzle, wherein the inner spray pipe and the outer spray pipe are coaxially arranged, and the spring spray nozzle is fixed at the bottom end of the inner spray pipe and is positioned at the bottom of an inner cavity of the outer spray pipe; a baffle ring is arranged between the outer wall of the inner spray pipe and the inner wall of the outer spray pipe, and an inlet which is used for inputting steam and is positioned below the baffle ring is arranged on the pipe wall of the outer spray pipe;
the bottom edge of the inner wall of the outer spray pipe is provided with a chamfer corresponding to the valve clack of the spring spray head, and a groove corresponding to the valve body of the spring spray head is also arranged above the chamfer.
The baffle ring is fixed with the top end of the inner spray pipe, the top end of the outer spray pipe is provided with a lower flange, the upper flange is fixed with the lower flange through bolts, and the check ring is tightly pressed and fixed between the lower flange and the upper flange.
And a bolt is arranged between the baffle ring and the lower flange.
The utility model has the advantages that:
the utility model discloses an use the medium to be water and steam to water is given first place to and steam is for assisting, just so can improve the utilization ratio of desuperheating water, reduces water route governing valve and spring nozzle's cooperation error, promotes spring nozzle's atomization effect, thereby with steam temperature accurate control in the design value.

Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
As shown in figure 1, the steam mixing temperature-reducing water spray head comprises an inner spray pipe 1, an outer spray pipe 2 and a spring spray head. The top end of the outer spray pipe is provided with a lower flange 6, the pipe wall of the outer spray pipe is provided with an inlet 1.1, the inlet is arranged in the lower flange, and an external temperature-reducing steam pipe 9 is connected with the inlet. The inner spray pipe is coaxially inserted into the outer spray pipe, the baffle ring 3 is arranged on the top surface of the outer spray pipe and is fixed with the top end of the inner spray pipe, the top of the outer spray pipe is also sealed by the baffle ring, and the inlet is positioned below the baffle ring.
An upper flange 7 is further arranged above the lower flange, the lower flange and the upper flange are fixed through a plurality of bolts, the check ring is tightly pressed and fixed between the lower flange and the upper flange, and an external temperature reduction water pipeline (omitted in the figure) is connected with the upper flange. The top surface of the lower flange and the bottom surface of the upper flange are also provided with concave platforms which are matched with the shape of the check ring, the edge of the check ring is provided with a first bayonet 3.1, the top surface of the lower flange is provided with a second bayonet (omitted in the figure) matched with the first bayonet, and the plug pin is inserted into the first bayonet and the second bayonet simultaneously to prevent the check ring and the inner spray pipe from rotating.
The spring shower nozzle is current structure. The spring spray head is fixed at the bottom end of the inner spray pipe and is also positioned at the bottom of the inner cavity of the outer spray pipe. As shown in fig. 2, in the spring nozzle, the upper part of a valve body 11 is fixed with an inner nozzle, a core bar 12 is axially slidably positioned in the valve body, the upper end of the core bar passes through the valve body and then is fixed with a rear seat 14, a valve clack 13 is arranged at the lower end of the core bar, a spring 15 is sleeved on the core bar and is positioned between the rear seat and the valve body, and a plurality of flow channels 16 are also formed on the valve body.
The bottom edge of the inner wall of the outer spray pipe is provided with a chamfer 5 which is annularly arranged, the height of the chamfer corresponds to the height of a valve clack of the spring spray head (the chamfer faces to the outer circumferential surface of the valve clack), a groove 4 which is annularly arranged is arranged above the chamfer, and the height of the groove corresponds to the height of a valve body of the spring spray head (the groove faces to the outer circumferential surface of the valve body). Therefore, a channel with a gradually contracted and expanded cross section is formed between the outer spray pipe and the spring spray head, the groove is a contracted section of the cross section of the channel, the chamfer is an expanded section of the cross section of the channel, and meanwhile, the outer circumferential surface of the valve clack is also provided with a valve clack chamfer corresponding to the chamfer of the outer spray pipe (the shape of the expanded section is similar to that of a horn mouth).
The utility model discloses a theory of operation is: desuperheating water lets in the spray tube and through the spring shower nozzle blowout, desuperheating steam lets in outer spray tube and removes along the intermediate layer between outer spray tube and the interior spray tube, desuperheating steam takes place to mix in the back with desuperheating water in outer spray tube bottom exit position and the pipeline 10, thereby effectively promoted the atomizing of desuperheating water, make the atomization effect of desuperheating water better, the utilization ratio of desuperheating water has been improved, ponding in the desuperheating water pipeline has been reduced, consequently ponding resonance has been avoided and the pipeline is damaged.
