Embodiment
Be described in further detail below in conjunction with the structure and the use principle of accompanying drawing anti-alluvial reverse-stop type hydathode provided by the utility model.
Shown in 1 figure, be the structural representation of anti-alluvial reverse-stop type hydathode provided by the utility model.Should anti-structure of depositing the reverse-stop type hydathode include: valve body 1, this valve body bottom is provided with the cylindrical shell 3 formation water intakes 4 that form step 2 with its inwall, the upper end portion of valve body is provided with the water outlet square body 5 that promptly can change of clamping or screw socket connection, this water outlet square body is provided with the tube ring 6 of the structure that is connected as a single entity with it, and be provided with the lid 9 of ring flange 8 on this ring by snapping, this lid 9 is connected with water outlet square body by nut by the screw rod attachment post 7 that is provided with; In valve body, constitute water intake cylindrical shell 3 the clamping of step place or be connected with the middle part by screw socket and be set with baffle ring sealed support circle 10, its roof anchorage and have in order to alleviate the spool that collision causes the cushion seal cushion rubber 11 that damages, and be equipped with movable circular ball bodies 12.
As shown in Figure 3, the reverse-stop type hydathode 14 of will preventing depositing is embedded in the concrete 13 during use, and makes the water outlet square body 5 that constitutes anti-alluvial reverse-stop type hydathode floating with the concrete surface at the bottom of the formation water channel.When the drift sand mud in the flowing water sinks to water channel when bottom, can form slope sand drift 22 at the periphery of 5 rings 6 of water outlet square body, and along with the increasing of mud drift sand, flowing water can wash away sand drift immediately.Therefore can prevent effectively that the mud drift sand from flowing backward in the hydathode by water outlet square body 5, avoid because the generation that enters feasible formation reverse-stop type hydathode spool failure phenomenon of silt mud.
The structure that constitutes this anti-alluvial reverse-stop type hydathode shows it can also is as shown in Figure 2 structure, promptly constitutes spool of this anti-alluvial reverse-stop type hydathode and the water converse stopping mechanism is set with the cylindrical shell 11 of baffle ring sealed support circle 10 by the end and the dodge gate 16 that is fixed on the baffle ring sealed support circle by rotating shaft 15 constitutes.
In the structure of this anti-alluvial reverse-stop type hydathode; the cylindrical shell 3 that is set with sealed support circle 10 can be that screw thread is fixed in the cylindrical shell of water intake; also can be to be connected on this cylindrical shell; its effect is exactly the cylindrical shell and the step 2 thereof that constitute water intake in order to protect, prevents to constitute the spheroid of water converse stopping mechanism and dodge gate and collides with it and cause damage.Be the branch body structure owing to be set with the cylindrical shell of sealed support circle 10 with the cylindrical shell 7 that constitutes water intake, can realize after the damage changing.
In order to realize keeping in repair and to change the spool that constitutes anti-alluvial reverse-stop type hydathode easily, the water outlet square body of fixing at valve body water outlet place 5, its periphery are provided with flute profile connection with it and protrude from the annular ring 17 of valve body outer side wall.After the valve body of anti-alluvial reverse-stop type hydathode is embedded in cement concrete, this annular ring that protrudes from the valve body outer side wall is removed formation hand groove 18 (shown in 3 figure).The existence of this hand groove can be used hand or instrument removal water outlet easily square body 5, realizes inboard set replacing and the maintenance that is equipped with spool in valve body chamber.
Combine more firmly in order to make between anti-alluvial reverse-stop type hydathode and concrete cement liner structure, and make that the water sealing property of the two is better, the outer side of valve body waist is provided with water-swellable O-ring seal 19 and is set with the fixing seal dish 21 of groove 20.Its further groove 20 is used for and being tightly connected of water-proofing material.
