In the figure, 1, a gas collecting pipe; 2. a spoiler; 3. a gas permeable member; 4. an exhaust valve; 5. a water inlet pipe; 6. a water outlet pipe; 7. an outward projection; 8. a dilatation region; 9. a flange plate; 10. air bubbles.
Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
The exhaust device of the closed water system shown in fig. 1 and 2 comprises a gas collecting pipe 1, a flow disturbing piece 2, a ventilating piece 3, an exhaust valve 4 and a pipeline; an outer protrusion part 7 is arranged on the gas collecting pipe 1 to form an expansion area 8; the turbulence piece 2 and the ventilation piece 3 are arranged in the gas collecting pipe 1 in a staggered way; the exhaust valve 4 is arranged on an external protrusion part 7 of the gas collecting pipe 1 and communicated with the expansion area 8; the pipelines are arranged at two ends of the gas collecting pipe 1, and the pipelines in the embodiment are divided into a water inlet pipe 5 and a water outlet pipe 6 according to the water flow direction in the water system. The two ends of the gas collecting pipe 1 are respectively provided with a flange 9, the water inlet pipe 5 and the water outlet pipe 6 can be respectively connected with the two ends of the gas collecting pipe 1 through the flanges 9, and of course, the water inlet pipe 5 and the water outlet pipe 6 can also be directly welded with the two ends of the gas collecting pipe 1.
In the embodiment, the outer protrusion part 7 is only arranged on one side of the gas collecting pipe 1, and the ventilating piece 3 is arranged in the expansion area 8; the turbulent member 2 is arranged on the inner wall of the gas collecting pipe 1 opposite to the expansion area 8. Taking fig. 1 as an example, when the exhaust device is horizontally installed, the upper end of the gas collecting pipe 1 is provided with an external protrusion 7, and the external protrusion 7 comprises a section of rising part gradually increasing along the water flow direction and a section of falling part gradually decreasing along the water flow direction. The boundary of the rising part and the lowering part is the highest point of the outward protrusion part 7, and can also be called as the top end of the outward protrusion part 7; the exhaust valve 4 is preferably provided at the tip of the protruding portion 7.
The air permeable member 3 in this embodiment is an exhaust grill. The spoiler 2 is a spoiler, which can be a plane plate or a grating plate. The spoiler 2 and the ventilation member 3 are arranged parallel to the radial surface of the header 1. As shown in fig. 1, the number of the air-permeable members 3 in the expansion area 8 is 3, and the air-permeable members are arranged at intervals; two turbulence pieces 2 are arranged on the inner wall of the gas collecting pipe 1 opposite to the expansion area 8 at intervals. The direction shown by the arrow in fig. 1 is a water flow direction, water flow in the closed water system enters the gas collecting pipe 1 through the water inlet pipe 5, and the expansion area 8 formed by the outer protruding part 7 increases the flow area of the gas collecting pipe 1, so that the water flow speed is reduced, and sufficient time and space are created for air discharge in the water system. Under the turbulent action of the turbulent member 2, the water flow is disturbed, and the air/bubbles 10 in the water flow "flee" upwards and pass through the exhaust grille, and then the air is gathered at the uppermost end of the gas collecting pipe 1, i.e. the top end of the outer protrusion 7 in the embodiment, and is exhausted through the exhaust valve 4 at the top end of the outer protrusion 7. The exhaust device with the special structure can quickly and efficiently discharge air in water flow, does not influence the pressure of a water system, and improves the stability and hydraulic balance of the water system.
