Abstract
A kind of water pipe safety check is rotatably connected frame, relate to valve technology field, it is characterized in that: comprise fixing frame, position-limited rack and bolt-revolving, described fixing frame is fixing to be connected with bolt-revolving, described position-limited rack is arranged on fixing frame by bolt-revolving is rotatable, described bolt-revolving offers into 90 degree of fan-shaped swivelling chutes, the avris that bolt-revolving is positioned at swivelling chute is provided with butterfly, mutually vertical between butterfly with position-limited rack, described butterfly and swivelling chute are all provided with two and center about bolt-revolving becomes to be symmetrical arranged.Structure is simple, reasonable in design, easy to use, non-return is effective, not easily stuck and leakage.
Description
Technical field:
The utility model relates to valve technology field, is specifically related to a kind of water pipe safety check and is rotatably connected frame.
Background technique:
Safety check is also known as one-way valve or check valve, and its effect prevents the medium in pipeline from flowing backwards.Usually, fluid makes the flap of valve open under pressure, and flows to outlet side from suction side.When suction side pressure is lower than outlet side, flap automatically by pathway closure, stops fluid countercurrent current under the effect of hydrodynamic pressure and gravity own.
Having a lot of valve blocks all to exist in current safety check often can not non-return or have can not the phenomenon of non-return completely; its main cause is not only because the valve block of valve internal often can be stuck; like this valve block will be made well not close thus affect normal work; and the non-return effect of single valve block is poor, easily reveals.
Model utility content:
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, reasonable in design, easy to use, non-return is effective, not easily water pipe safety check that is stuck and that reveal to be rotatably connected frame.
Technical problem to be solved in the utility model adopts following technological scheme to realize:
A kind of water pipe safety check is rotatably connected frame, it is characterized in that: comprise fixing frame, position-limited rack and bolt-revolving, described fixing frame is fixing to be connected with bolt-revolving, described position-limited rack is arranged on fixing frame by bolt-revolving is rotatable, described bolt-revolving offers into 90 degree of fan-shaped swivelling chutes, the avris that bolt-revolving is positioned at swivelling chute is provided with butterfly, mutually vertical between butterfly with position-limited rack, described butterfly and swivelling chute are all provided with two and center about bolt-revolving becomes to be symmetrical arranged.
The length of described butterfly is identical with the width of swivelling chute.
Described fixing frame and position-limited rack are all evenly provided with fixed bolt.
The beneficial effects of the utility model are: structure is simple, reasonable in design, easy to use, non-return is effective, non-return is effective, not easily stuck and leakage.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of water pipe safety check is rotatably connected frame, comprise fixing frame 1, position-limited rack 2 and bolt-revolving 3, fixing frame 1 is fixing to be connected with bolt-revolving 3, position-limited rack 2 is arranged on fixing frame 1 by bolt-revolving 3 is rotatable, bolt-revolving 3 offers into 90 degree of fan-shaped swivelling chutes 4, the avris that bolt-revolving 3 is positioned at swivelling chute 4 is provided with butterfly 5, mutually vertical between butterfly 5 with position-limited rack 2, butterfly 5 is all provided with two with swivelling chute 4 and center about bolt-revolving 3 becomes to be symmetrical arranged.The length of butterfly 5 is identical with the width of swivelling chute 4.Fixing frame 1 and position-limited rack 2 are all evenly provided with fixed bolt 6.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
