Abstract
The invention relates to a check valve. The check valve comprises a check valve body and a base, wherein a connecting block is arranged around the connecting end of the check valve body and the base; at least two clamping blocks are arranged on the connecting block and are symmetric about the center of the check valve body; at least two corresponding clamping grooves are arranged in the base; and the clamping blocks are clamped in the clamping grooves. The check valve disclosed by the invention has the beneficial effects that threaded holes are also formed in the connecting block; screw holes are formed in the positions, which are corresponding to the threaded holes, of the base; screws sequentially penetrate the check valve and the base; and therefore, the tightness between the check valve and the base is greatly increased and the situation that the check valve and the base are loosened or separated, caused by external reasons, does not occur.
Description
Technical field
The present invention relates to a kind of check-valves.
Background technology
Require also more and more higher now for the comfort level within house house.In current Central Gas Exhaust Systems in Residential Building, it is possible to produce flue gas refluence phenomenon, cause the probability that string fire occurs, therefore prevent the check-valves of smoke backflow from thus arising at the historic moment.Opening and closing element opens or closes voluntarily close by media flow and strength, to prevent valve that medium flows backwards on check-valves.Check-valves belongs to automatic valve class, is mainly used on the pipeline of medium one-way flow and only allows medium to flow to a direction, to try to avert accidents.Existing check-valves of a great variety, existing check-valves generally comprises check valve body and base, due to the connected mode defective tightness of check valve body Yu base, it is easy to loosen.
Summary of the invention
In order to overcome the deficiency connecting defective tightness in prior art between existing check valve body and base, the present invention provides and connects very close check-valves between a kind of check valve body and base.
To achieve these goals, this invention address that the technical scheme of its technical problem is:
A kind of check-valves, including check valve body and base, the link of check valve body and described base be formed around contiguous block, contiguous block is provided with fixture block, and base is provided with draw-in groove, and fixture block is fastened in draw-in groove；At least provided with two fixture blocks on contiguous block, and fixture block is about the centrosymmetry of check valve body；At least provided with corresponding at least two draw-in groove on base.
Being additionally provided with screwed hole on contiguous block, the base corresponding with screwed hole is provided with screw, and screw sequentially passes through screwed hole and screw.
Beneficial effects of the present invention: adopt above-mentioned technical pattern, first, the link of check valve body and base be formed around contiguous block, contiguous block is provided with fixture block, base is provided with draw-in groove, and fixture block is fastened in described draw-in groove, so that check valve body is fastened on base closely.Therefore easy installation and removal between check valve body and base, and connect very tight, it is not easy to loosen.Secondly, at least provided with two described fixture blocks on contiguous block, and fixture block is about the centrosymmetry of check-valves；At least provided with two corresponding described draw-in grooves on base.Make the connection between check valve body and base more tight.Finally, contiguous block is additionally provided with screwed hole, the base corresponding with screwed hole is provided with screw, screw sequentially passes through check valve body and base, so that the compactness between check valve body and base is greatly improved, more will not cause producing between check valve body with base to loosen or separate because of extraneous reason.
Accompanying drawing explanation
Fig. 1 is check-valves sectional view of the present invention.
Detailed description of the invention
A kind of check-valves, including check valve body 1 and base 2, the link of described check valve body 1 and described base 2 be formed around contiguous block 3, described contiguous block 3 is provided with fixture block 4, and described base 2 is provided with draw-in groove 5, and described fixture block 4 is fastened in described draw-in groove 5.In the present embodiment, at least provided with two described fixture blocks 4 on described contiguous block 3, and described fixture block 4 is about the centrosymmetry of check valve body 1；At least provided with two corresponding described draw-in grooves 5 on described base 2, and described draw-in groove 5 is mutually symmetrical with.Being additionally provided with screwed hole on described contiguous block 3, the base 2 corresponding with described screwed hole is provided with screw, and screw sequentially passes through check valve body 1 and base 2, so that being connected more closely between check valve body 1 with base 2.
Adopt above-mentioned technical pattern, first, the link of check valve body and base be formed around contiguous block, contiguous block is provided with fixture block, and base is provided with draw-in groove, and fixture block is fastened in described draw-in groove, so that check valve body is fastened on base closely.Therefore easy installation and removal between check valve body and base, and connect very tight, not easily loosen.Secondly, at least provided with two described fixture blocks on contiguous block, and fixture block is about the centrosymmetry of check-valves；At least provided with two corresponding described draw-in grooves on base.Make the connection between check valve body and base more tight.Finally, contiguous block is additionally provided with screwed hole, the sole corresponding with screwed hole is provided with screw, screw sequentially passes through check valve body and base, so that the compactness between check valve body and base is greatly improved, more will not cause producing between check valve body with base to loosen or separate because of extraneous reason.
