FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a bottom view of the deflector base of the present invention.
In the figure: 1. the high-pressure steam guide box comprises a guide box body 2, a high-pressure steam inlet pipe 3, a spiral pipe 4, a circular ring 5, a mounting hole 6, a guide seat 7, a screw rod 8, a nut 9, a spring 10, a connecting rod 11, a cross-shaped grid plate 12, a baffle plate 13 and a through hole.
Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings 1-2.
The utility model provides a steam buffer in tombarthite production, includes flow guide box 1, and wherein the downside of flow guide box 1 is equipped with and extends to its inside high-pressure steam and advances pipe 2, high-pressure steam in flow guide box 1 advances pipe 2 and goes up the overcoat and have the screwed pipe 3 rather than the spiro union is fixed, and wherein the overcoat has ring 4 on the screwed pipe 3, and evenly is provided with mounting hole 5 on the ring 4, still be provided with the coniform water conservancy diversion seat 6 that is located high-pressure steam and advances pipe 2 export department directly over in flow guide box 1, wherein the setting of back-off of water conservancy diversion seat 6 to be 30 to 45 degrees contained angles between the bottom inclined plane of water conservancy diversion seat 6 and the horizontal plane, be provided with the screw rod 7 that passes corresponding mounting hole 5 on the bottom face of water conservancy diversion seat 6 simultaneously, the spiro union has the nut 8 that is located both sides about ring 4 on the screw rod 7, wherein all overcoat has spring 9 on the screw rod 7 that is located between nut 8 and the ring 4.
In this embodiment, the outer side wall of the high pressure steam inlet pipe 2 is provided with a thread screwed with the spiral pipe 3, wherein the spiral pipe 3 and the ring 4 are integrally arranged.
Wherein advance the mode of pipe 2 spiro union with high-pressure steam through solenoid 3 in order to make things convenient for the installation between the two to still can be unsettled with ring 4 and fix in the eminence, simultaneously through ring 4 and the mode of spring 9 support nut 8 with screw rod 7 activity fixation in mounting hole 5 to and fix the eminence with water conservancy diversion seat 6 is unsettled through screw rod 7, prevent screw rod 7 from slipping out and prevent that spring 9 from the screw rod 7 in the above-mentioned in-process through nut 8 and spring 9.
When the steam introduced from the high-pressure steam inlet pipe 2 contacts with the bottom end surface of the diversion seat 6, the steam is guided by the bottom inclined surface and flows towards the four sides of the diversion seat, so that the purpose of deflecting the inflowing steam to buffer and decelerate is achieved, and the introduced steam is prevented from directly impacting the side wall of the diversion box 1 upwards and causing damage to the side wall.
When steam impacts the bottom end surface of the flow guide seat 6, the flow guide seat 6 can be pushed to move upwards and drive the screw 7 to move in the mounting hole 5, the spring 9 is extruded by the nut 8 to be contracted and expanded, the flow guide seat 6 is buffered and damped, the jittered flow guide seat 6 can play a turbulent flow role on the steam to reduce the speed of the steam, and the steam is prevented from being easily damaged after being blown to the flow guide seat 6 for a long time.
The position of the screw rod 7 can be changed by rotating the nut 8 in a specific operation process, and the purpose of adjusting the distance between the flow guide seat 6 and the top end of the high-pressure steam inlet pipe 2 is achieved, wherein the inclined surface at the bottom of the flow guide seat 6 is convenient for gas to flow along the inclined surface, meanwhile, when parts such as the flow guide seat 6 and the like need to be replaced, the parts such as the screw pipe 3, the ring 4, the flow guide seat 6 and the like can be taken down for replacement or maintenance only by rotating the screw pipe 3 to separate the parts from the high-pressure steam inlet pipe 2, meanwhile, the nut 8 can be screwed down to draw out the screw rod 7 from the mounting hole 5, and the buffer device is further disassembled into a plurality of small parts, so that the replacement or maintenance of the parts is convenient, the whole buffer device does not need to be replaced, and undamaged components can be recycled to save cost.
As shown in fig. 1, a connecting rod 10 extending into the opening of the high-pressure steam inlet pipe 2 is further disposed in the middle of the bottom of the flow guide seat 6, wherein a cross-shaped grid plate 11 is disposed at the bottom end of the connecting rod 10, through holes 13 are uniformly disposed on the side wall of the cross-shaped grid plate 11, and a plurality of groups of curved baffle plates 12 are radially disposed on the bottom end surface of the flow guide seat 6 located outside the connecting rod 10.
The steam flowing out of the high-pressure steam inlet pipe 2 is separated through the cross grid plate 11, so that the steam is discharged from four separated different areas and uniformly covers the bottom end face of the flow guide seat 6, the steam is prevented from flowing out of one side of the opening of the high-pressure steam inlet pipe 2, and the steam is only blown to one side of the bottom of the flow guide seat 6 to influence the buffering and speed reducing effect of the flow guide seat 6 on the steam. The through holes 13 facilitate the air circulation between the four sides of the cross grid 11. And because the cross grid plate 11 is connected with the guide seat 6 through the connecting rod 10, the guide seat 6 can be disassembled, and the cross grid plate 11 can be drawn out from the high-pressure steam inlet pipe 2 through the connecting rod 10, otherwise, the same effect can be achieved during the installation.
Meanwhile, when steam blows to the bottom end face of the flow guide seat 6 and diffuses around along the inclined plane, the arc-shaped face of the baffle plate 12 can play a role in turning to speed reduction buffering for gas flowing at the bottom end face of the flow guide seat 6, and further the gas diffusing around is prevented from damaging the side wall of the flow guide box 1.
The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
