Preferably, the shower guide valve consists of two shower guide plates which are mutually overlapped, and the screw holes on the shower guide valve are arranged on the shower guide plates.
Preferably, a sealing gasket is arranged between the two stacked shower guide plates.
Preferably, the upper cover is a round cover plate formed by butt-jointing two semicircular plates with equal diameters.
Preferably, two sealing baffles are arranged at the splicing positions of the two semicircular plates along the direction perpendicular to the semicircular plates.
Preferably, a sealing filler is arranged between the sealing baffles; the middle section part of the shower guide pipe penetrates through the sealing filler.
Preferably, the accommodating cavity is provided with a liquid outlet.
Preferably, the number of the screws is four, and the screws are symmetrically arranged.
Preferably, the accommodating cavity is further provided with an exhaust valve.
Preferably, the outer edge of the accommodating cavity and the outer edge of the upper cover are fixed together through a clamping bolt.
Compared with the prior art, the technical scheme of the invention has the advantages that the invention is successfully applied to online liquid discharge operation, avoids the risks of production stoppage, leakage, combustion explosion and the like possibly caused by improper operation due to pressurized blasting purging, reduces environmental pollution and waste caused by emission, and provides safety guarantee for condensate treatment; the novel online discharge mode is provided, the structure is compact, the safety and the reliability are realized, and the operation is simple; provides a new idea for on-line maintenance of the pressurized hole and the like. The flange can be applied to the online disassembly and discharge work of the blind flange of the pipe throwing head in the industries of petrochemical industry, fuel gas, water supply and drainage and the like, and creates favorable conditions for the subsequent installation of valves, pressurized tapping of low-temperature pipes, connection of new pipes and the like.

Detailed Description
Embodiment 1 this embodiment discloses a pipeline flowing back device (specifically as shown in fig. 1-3), the device comprises upper cover 11, accommodation chamber 8, the central point of upper cover puts and runs through and is provided with a guide and drenches pipe 3, guide drenches the pipe 3 open end and is provided with a guide and drenches the valve.
The shower guide valve consists of two shower guide plates 7 which are mutually overlapped, screw holes are formed in the shower guide plates 7, and the other ends of the screws penetrate through the screw holes. The shape and the size of the two shower guide plates 7 are the same, four screw holes are correspondingly formed in the two shower guide plates respectively, 2 screw holes are correspondingly formed in the upper cover 11, the two shower guide plates 7 and the upper cover 11 are connected through two screws, so that the upper cover 11 is connected with the shower guide valve, and the shower guide pipe is also connected with the shower guide valve; a sealing gasket 6 is arranged between the two shower guide plates.
The upper cover 11 is a round cover plate formed by butt-jointing two semicircular plates with equal diameters. The accommodating chamber 8 is integrally connected with the upper cover through a clamping bolt 12.
