Abstract
The utility model belongs to the technical field of valves and particularly relates to an anti-siltation check type drainer used in water conservancy projects. The technical scheme is as follows: the anti-siltation check type drainer includes a valve body, wherein the bottom of the valve body is provided with a water inlet, the upper end of the valve body is provided with a water outlet, a water check mechanism is arranged in a valve body cavity, a cap body provided with a skirt border is covered on the valve body, and the skirt border of the cap body is fixedly connected with a supporting strip on the outer wall of the valve body. The anti-siltation check type drainer and a structure thereof with an anti-siltation function ensure double anti-siltation effects, and the anti-siltation check type drainer can be widely used in water conservancy projects such as channels and reservoirs under the condition of high underground water level.
Description
Technical field
The utility model belongs to valve technology field, relates in particular to a kind of anti-alluvial reverse-stop type hydathode that is used in the hydraulic engineering.
Background technique
The reverse-stop type hydathode is the hydraulic engineering such as channel, wet pit that is specially adapted under the phreatic high situation; Its objective is and subdue the seepage pressure and floating holder influence of underground water, reach thickness, the assurance structural safety of reducing investment outlay that reduces liner structure and improve the structure purpose in working life liner structure.The structure that constitutes the reverse-stop type hydathode mainly comprises: be provided with the valve body that water intake, upper end portion are provided with water outlet by the bottom, be provided with the spool that the water converse stopping mechanism constitutes in the valve body chamber, the water outlet of valve body is provided with the water outlet square body that can change.The reverse-stop type hydathode of this structure is particularly suitable for not having using in the wet pit engineering of drift sand mud; But when the hydraulic engineering of flowing water such as channel is used, can because sink to the channel bottom drift sand mud through in the water outlet square body entering valve body, the shutoff of water converse stopping mechanism is appearred the problem of this reverse-stop type hydathode loss of function.
The utility model patent that Chinese patent number is 201020261917.4, publication number is CN201715044U discloses a kind of alluvial reverse-stop type hydathode.Its structure is provided with the water outlet square body that can change for the water outlet at valve body, and this water outlet square body is provided with the tube ring that is connected as a single entity with it, is snapped with a lid that is provided with the ring flange on the tube ring.Ring flange and lid can effectively prevent than the heavy alluvial problem like passing things such as silts of water, can get in the valve body chamber with water with the suspended thing of water compatible but be difficult to solve, and the problem that deposition alluvial obstruction water converse stopping mechanism causes its loss of function takes place.But the water outlet of this hydathode valve body is owing to be in normal open state, subtracts silt effect and not obvious for suspended pledge.
The utility model patent that Chinese patent number is 201020261917.4, publication number is CN201715044U discloses a kind of alluvial reverse-stop type hydathode.This reverse-stop type hydathode can effectively prevent than the heavy alluvial problem of passing thing like silt etc. of water, and Chinese patent number is that the utility model patent of CN200964580Y discloses the stifled reverse-stop type hydathode of a kind of anti-silt for 200620011447.X, publication number.The structure that constitutes this reverse-stop type hydathode includes valve body, the hinged valve plate that is provided with water intake, the anti-silt cover formation that is arranged at the guiding trestle in the valve body chamber and is connected with guide rod.There is following defective in the reverse-stop type hydathode of this structure: when the alluvial of passing thing surpasses the height of valve; Moving the back shoal materials on its anti-cover that becomes silted up can oppositely get in the valve pocket and deposition; Cause the anti-cover loss of function of becoming silted up when sludge causes guide rod in the guiding trestle to stop up after malfunctioning, when sludge causes valve plate to stop up, can make its valve function forfeiture.
The model utility content
The hydraulic engineering that the technical problem that the utility model will solve provides flowing water such as a kind of channel is used and can be prevented to get into the anti-alluvial reverse-stop type hydathode in the valve body chamber simultaneously to passing thing such as silt and suspended thing.
For realizing above-mentioned purpose, the technological scheme that the utility model adopted is:
A kind of anti-alluvial reverse-stop type hydathode, its structure comprise that the bottom is provided with the valve body that water intake, upper end portion are provided with water outlet, is provided with the water converse stopping mechanism in the valve body chamber; At described valve upper cover a cap body that is provided with the shirt rim is arranged, the shirt rim of said cap body is fixedly connected with supporting bar on the said valve outer wall.
A kind of anti-alluvial reverse-stop type hydathode that the utility model provided compared with prior art; Because the valve upper cover constituting the reverse-stop type hydathode has a cap body that is provided with the shirt rim; The shirt rim of this cap body is fixedly connected with supporting bar on being arranged at valve outer wall; And the formation exhalant canal, make in this hydathode whose to flow out through this passage, and owing to should be lower than the water level of water outlet in the shirt rim of hydathode valve body uppercap body; Make suspended thing by this shirt rim retaining beyond the cap body, also can not flow backward to water outlet and get in the valve pocket even the draining water outlet is in the suspended thing of normally open through passage; Silt etc. are passed thing more can not get into valve pocket.Therefore reverse-stop type hydathode and the anti-alluvial function that structure had of itself make it have the double effects of anti-alluvial.
Description of drawings
The structural representation of the anti-alluvial reverse-stop type hydathode that Fig. 1 provides for the utility model;
Fig. 2 is second kind of structural representation of anti-alluvial reverse-stop type hydathode.
Embodiment
Below in conjunction with accompanying drawing the structure and the use principle of the anti-alluvial reverse-stop type hydathode that the utility model provided are done further to specify.
As shown in Figure 1, be the structural representation of the anti-alluvial reverse-stop type hydathode that the utility model provided.The structure of this reverse-stop type hydathode comprises: the outer wall border axially is provided with the valve body 1 of some supporting bars 5; The water intake 4 that its bottom is provided with, the spool 12 of formation water converse stopping mechanism, the upper end portion of valve body is provided with the clamping of water outlet 2 or the water outlet square body 3 that promptly can change that screw socket connects; Be arranged on the tube ring 6 of the structure that is connected as a single entity with it on the water outlet square body; On this ring, be provided with the lid 8 of anti-alluvial of ring flange 7 through snapping, this lid 8 is connected with water outlet square body 3, at above-mentioned valve upper cover a cap body 10 that is provided with shirt rim 9 is arranged; The shirt rim of this cap body is fixedly connected with supporting bar on the valve outer wall, and the two forms exhalant canal 11.
Be illustrated in figure 2 as the structural representation of another kind of anti-alluvial reverse-stop type hydathode.Promptly the structure of this reverse-stop type hydathode comprises: be provided with the water converse stopping mechanism spool 12 that the valve body 1 that water intake 4 and outer wall border axially be provided with some supporting bars 5, hinged valve plate constitute, the anti-silt cover that is arranged at the guiding trestle in the valve body chamber and is connected with guide rod; At above-mentioned valve upper cover a cap body 10 that is provided with shirt rim 9 is arranged; The shirt rim of this cap body is fixedly connected with supporting bar on the valve outer wall, and the two forms exhalant canal 11.
