Abstract
The utility model belongs to a filter flask water leakage prevention device, and particularly relates to a filter flask device for preventing water leakage caused by water hammer shock. The filter flask water leakage prevention device comprises a flask body, a filter flask cap and an O-shaped ring, wherein the filter flask cap is in threaded connection with the flask body; the O-shaped ring is arranged between the flask body and the filter flask cap; the flask body is provided with a flask body internal thread; the filter flask cap is provided with a filter flask cap outer thread matched with the flask body internal thread; a flexible rubber gasket is also arranged between the flask body and the filter flask cap. According to the utility model, the flexible rubber gasket is also arranged between the flask body and the filter flask cap, and friction increases between the flask body and the filter flask cover via the flexible rubber gasket so as to effectively prevent the problem of water leakage because of thread rotation and loosening caused by water hammer shock.
Description
Technical field
The utility model belongs to filter flask leakage-proof apparatus, specifically relates to a kind of preventing water hammer impact and causes the filter flask device leaking.
Background technology
What modernization household tap water tap mostly was water saving opens tap soon, open soon tap and open soon water saving simultaneously easily providing, also can bring harmful water hammer to water supply pipe, so-called water hammer, because opening soon leading quick closedown, running water mobile in pipeline is stopped abruptly, the effect of inertia moment of water produces the pulse hydraulic pressure that is several times as much as the specified hydraulic pressure of running water in pipeline, this pulse hydraulic pressure effect is referred to as water hammer, and valve, water terminal that the accumulation meeting of impact of water hammer is connected to water supply pipe and with water supply pipe are brought destructive lesion.After long-time impact, this phenomenon is easy to cause threaded plastic cement filter flask on appliance water purifier, and the accessories such as quick union get loose and leak, and as user does not find in time, cause damage, consequence is very serious.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of respond well preventing water hammer impact and causes the filter flask device leaking.
Content of the present utility model be comprise the filter flask lid that bottle and bottle are threaded and be arranged on bottle and filter flask lid between o type circle, on described bottle, be provided with bottle internal thread, described filter flask covers the filter flask lid external screw thread being provided with bottle screw-internal thread fit, between described bottle and filter flask lid, is also provided with flexible glue pad.
On described bottle internal thread, be provided with internal thread concave point, on described filter flask lid external screw thread, be provided with the external screw thread projection matching with internal thread concave point.
The number of described external screw thread projection and internal thread concave point is respectively at least one.
The beneficial effects of the utility model are, the utility model is also provided with flexible glue pad between described bottle and filter flask lid, between bottle and filter flask lid by flexible glue pad increasing friction force, can effectively anti-sealing impact of water hammer and cause the loosening problem of leaking of screw thread rotation.
The utility model is provided with internal thread concave point on bottle internal thread, on described filter flask lid external screw thread, be provided with the external screw thread projection matching with internal thread concave point, described external screw thread projection and internal thread concave point are in the process that filter flask lid and bottle rotate mutually, mutually mate at certain position, realize the function of screens stop, can effectively prevent impact of water hammer and cause screw thread rotation loosening, thereby effectively prevent the generation of drainage.
The utility model can arrange several external screw thread projections and internal thread concave point at relevant position simultaneously, can strengthen like this being closely connected between filter flask lid and bottle, prevents the impact of water hammer on filter flask lid and bottle, prevents the generation of drainage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of external screw thread projection.
Fig. 3 is the structural representation of internal thread concave point.
In the drawings, 1 filter flask lid, 2o type circle, 3 bottle internal threads, 4 bottles, 5 filter flask lid external screw threads, 6 external screw thread projections, 7 internal thread concave points, 8 flexible glue pads.
Detailed description of the invention
As Figure 1-3, the utility model comprise the filter flask lid 1 that bottle 4 and bottle 4 are threaded and be arranged on bottle 4 and filter flask lid 1 between o type circle 2, on described bottle 4, be provided with bottle internal thread 3, on described filter flask lid 1, be provided with the filter flask lid external screw thread 5 coordinating with bottle internal thread 3, between described bottle 4 and filter flask lid 1, be also provided with flexible glue pad 8.
On described bottle internal thread 3, be provided with internal thread concave point 7, on described filter flask lid external screw thread 5, be provided with the external screw thread projection 6 matching with internal thread concave point 7.
The number of described external screw thread projection 6 and internal thread concave point 7 is respectively at least one.
The utility model is also provided with flexible glue pad 8 between described bottle 4 and filter flask lid 1, between bottle 4 and filter flask lid 1 by flexible glue pad 8 increasing friction forces, can effectively anti-sealing impact of water hammer and cause the loosening problem of leaking of screw thread rotation.
The utility model is provided with internal thread concave point 7 on bottle internal thread 3, on described filter flask lid external screw thread 5, be provided with the external screw thread projection 6 matching with internal thread concave point 7, described external screw thread projection 6 and internal thread concave point 7 are in the process of filter flask lid 1 and bottle 4 mutual rotations, mutually mate at certain position, realize the function of screens stop, can effectively prevent impact of water hammer and cause screw thread rotation loosening, thereby effectively prevent the generation of drainage.
The utility model can arrange several external screw thread projections 6 and internal thread concave point 7 at relevant position simultaneously, can strengthen like this being closely connected between filter flask lid 1 and bottle 4, prevents the impact of water hammer on filter flask lid 1 and bottle 4, prevents the generation of drainage.
