Abstract
The utility model discloses a slow-closure type vertical and horizontal check valve. The slow-closure type vertical and horizontal check valve comprises a valve body, wherein a fluid channel inlet and a fluid channel outlet are formed in the valve body in a fitting manner; a sealing surface is arranged at the fluid channel inlet; a large valve clack in sealing fit with the sealing surface is arranged in the valve body; the inner end of the large valve clack is fixedly connected with a guide sleeve; a support frame is fixed in the valve body; the guide sleeve is slidably connected with the support frame; the large valve clack is connected to the support frame by a main spring. The slow-closure type vertical and horizontal check valve disclosed by the utility model is reasonable in structural design and capable of guaranteeing complete sealing in case of being installed vertically or horizontally or in other directions; the design of the main spring and an auxiliary spring plays a role of slow closure in case of a high pressure, so as to protect the sealing surface and prevent leakage caused by the breakage of the valve clack due to the too fast flow speed of a medium simultaneously; a guide rib and the guide sleeve in the valve body play a role of double-layer guide; the slow-closure type vertical and horizontal check valve is safe and convenient to use.
Description
Technical field
The utility model belongs to valve technology field, relates to the vertical sleeping safety check of a kind of slow-closing type.
Background technique
Safety check claims again one-way valve or check valve, and its effect is to prevent that the medium in pipeline from flowing backwards.Open-shut device is opened voluntarily or closes by media flow and strength, to prevent that valve that medium flows backwards is on safety check.Safety check belongs to self-acting valve class, is mainly used on the pipeline of medium one-way flow, only allows medium to flow to a direction, to try to avert accidents.Common safety check can only found dress, and sleeping dress or other directions are installed all may cause leakage because sealing is imperfect, uses very inconvenient.
Model utility content
The purpose of this utility model is to provide the vertical sleeping safety check of a kind of slow-closing type, has solved general check valve in prior art and has been only suitable for vertical dress, is not suitable for the technical problem that sleeping dress or other directions are installed.
The technological scheme that the utility model adopts is: the vertical sleeping safety check of this slow-closing type, comprise valve body, on described valve body, be equipped with fluid passage import, fluid passage outlet, fluid passage inlet is provided with sealing surface, the big valve flap being sealed and matched with sealing surface is set in valve body, and the inner of big valve flap is fixedly connected with guide sleeve, in described valve body, is fixed with supporting frame, guide sleeve and supporting frame are slidably connected, and described big valve flap is connected on supporting frame by main spring.
Optimization as technique scheme: big valve flap is provided with little fluid passage, in little fluid passage, be equipped with primary sealing surface, described big valve flap is provided with guide sleeve joint the inner chamber communicating with little fluid passage, guide sleeve is hollow structure and communicates with inner chamber, in little fluid passage, be provided with the little flap being sealed and matched with primary sealing surface, the left and right sides of little flap is slidably connected in inner chamber, and one end of described little flap is connected with guide sleeve by auxiliary spring.
Further optimization as technique scheme: guide sleeve and supporting frame joint are provided with oilless bearing.
Further optimization again as technique scheme: guide sleeve and big valve flap are fixed by hexagon socket head cap screw.Supporting frame and valve body are fixed by hexagon socket head cap screw.
Further optimization as technique scheme: be provided with the guiding rib that big valve flap is play the guiding role in valve body.
The beneficial effects of the utility model are: the utility model reasonable in design; when vertical dress, sleeping dress or other directions are installed; can guarantee to seal complete; Slow Close effect is played in the design of main spring and auxiliary spring in the situation that pressure is high; protection sealing surface; also prevent from because velocity of medium is too fast, flap being hit to split causing leakage, guiding rib and the guide sleeve of valve body the inside play double-deck leading role simultaneously, use safety, convenient.Increase hexagon socket head cap screw and fixed, made safety check more firm, strengthened working life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein: 1 valve body, 2 big valve flaps, 3 main springs, 4 little flaps, 5 auxiliary springs, 6 hexagon socket head cap screws, 7 guide sleeves, 8 supporting frames, 9 oilless bearings, 10 guiding ribs, 11 fluid passage imports, 12 fluid passage outlets, 13 sealing surfaces, 14 little fluid passages, 15 primary sealing surfaces, 16 inner chambers.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The vertical sleeping safety check of slow-closing type of the present utility model, comprise valve body 1, on described valve body 1, be equipped with fluid passage import 11, fluid passage outlet 12, import 11 places in fluid passage are provided with sealing surface 13, the big valve flap 2 that the interior setting of valve body 1 and sealing surface 13 are sealed and matched, the inner of big valve flap 2 is fixedly connected with guide sleeve 7, in described valve body 1, is fixed with supporting frame 8, guide sleeve 7 is slidably connected with supporting frame 8, and described big valve flap 2 is connected on supporting frame 8 by main spring 3.Big valve flap 2 is provided with little fluid passage 14, in little fluid passage 14, be equipped with primary sealing surface 15, described big valve flap 2 is provided with guide sleeve 7 joints the inner chamber 16 communicating with little fluid passage 14, guide sleeve 7 is hollow structure and communicates with inner chamber 16, in little fluid passage 14, be provided with the little flap 4 being sealed and matched with primary sealing surface 15, the left and right sides of little flap 4 is slidably connected in inner chamber 16, and one end of described little flap 4 is connected with guide sleeve 7 by auxiliary spring 5.Guide sleeve 7 is provided with oilless bearing 9 with supporting frame 8 joints.Guide sleeve 7 is fixing by hexagon socket head cap screw 6 with big valve flap 2.Supporting frame 7 is fixing by hexagon socket head cap screw 6 with valve body 1.In valve body 1, be provided with the guiding rib 10 that big valve flap 2 is play the guiding role.Valve is integral type structure.
The utility model reasonable in design; when vertical dress, sleeping dress or other directions are installed; can guarantee to seal complete; Slow Close effect is played in the design of main spring 3 and auxiliary spring 5 in the situation that pressure is high; protection sealing surface 13; also prevent from because velocity of medium is too fast, flap being hit to split causing leakage, guiding rib 10 and the guide sleeve 7 of valve body the inside play double-deck leading role simultaneously, use safety, convenient.Increase hexagon socket head cap screw 6 fixing, made safety check more firm, strengthened working life.
