Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
As depicted in figs. 1 and 2, a kind of limiting device of valve, including valve body 1, wherein valve body 1 is provided with sphere 2, and ball
Body 2 offers through-hole 3, therefore the utility model is using ball valve principle, using rotating sphere 2, thus control through-hole 3 and valve
The non-overlapping region of body 1, and then control the flow velocity and flow of water.
Sphere 2 is connected with valve rod 4 simultaneously, and by rotation valve rod 4 come rotating sphere 2, and valve body 1 is provided with polygonal hole
5, the valve rod 4 is shaped to the polygon to match with polygonal hole 5, so that valve rod 4 be made to be able to achieve certain angle with valve body 1
Rotary spacing.
In actual use, when the circular arc face contact of valve rod 4 and polygonal hole 5, valve rod 4 can freely turn
It is dynamic, and when valve rod 4 be located at polygonal hole 5 arc surface and plane intersection when, valve rod 4 is hindered, so stop to
Preceding movement, but can counter motion.Therefore the movement that valve rod 4 is hindered by the arc surface of polygonal hole 5 and the intersection of plane, from
And the range of the rotation of valve rod 4 is limited, and then limit the flow velocity of water and the range of flow.
In short, the utility model is matched by polygonal hole 5 with the valve rod 4 of polygon, the rotation of certain angle is realized
Limit, to realize limit and control the function of water flow, compared to the method for one limited block of increase of more original use, i.e.,
Limit is realized by the cooperation of limited block and valve rod, which is simplified, while keeping structure simpler stable
Keep processing and installation more convenient.
In conjunction with Fig. 4, Fig. 5 and Fig. 7, Fig. 6 is specifically seen, it is known that it is limited that a kind of specific limit method is that polygonal hole 5 includes
Position portion 7 and rotating part 8, rotating part, 8 are arranged between limiting section 7, and limit seamed edge 9 is provided between rotating part 8 and limiting section 7,
It is connected on limit seamed edge 9 by the valve rod 4, and then valve rod 4 is made to stop operating.
In actual use, when valve rod 4 is located at rotating part 8, valve rod 4 is free to rotate, and when valve rod 4 blocks
It connects when limiting on seamed edge 9, then valve rod 4 is hindered, and then stops travelling forward, but can counter motion.Therefore pass through valve rod 4
It is connected on limit seamed edge 9, to hinder the movement of valve rod 4, realizes the rotary spacing of certain angle, and then limit valve rod 4
The range of rotation makes to add while structure is more stable to limit the flow velocity of water and the range of flow using simple structure
Work is convenient.
And the polygonal hole 5 in specific limit method is by symmetrical two planes and symmetrical two circular arcs herein
Face is formed, and corresponding to valve rod 4 is octagon, wherein being longer sides there are two side, in addition six sides are shorter, to be formed flat
Shape.It is released respectively by six shorter sides and plane with arc surface, to form the rotary spacing of certain angle.
Certainly only said a kind of shape here, i.e., polygonal hole 5 is quadrangle, while valve rod 4 is octagon, so
In addition to this other polygons be can also be, therefore this is only merely a kind of citing of more excellent mode.
Valve rod 4 is connected with switch 10 simultaneously, and switch 10 is installed on valve rod 4 by fixing piece, and 10 pairs of switch
Claiming setting, there are two rotatable lamellas 12.Thus in actual use, by rotating 12 rotation valve rod 4 of rotatable lamella, thus
Drive sphere 2.It is easy to process while keeping structure more stable using simple structure.
And for beauty, 10 top of switch is provided with the decoration 11 for covering internal structure, passes through decoration
11 shelter from internal connection and part.
The connection type of valve rod 4 and sphere 2 between the two is that valve rod 4 is provided with protrusion 16, while sphere offers simultaneously
Slot 17 is connected in slot 17 by protrusion 16, and then is connected to valve rod 4 on sphere 2, to be rotated by rotation valve rod 4
Sphere 2, and control the flow velocity and flow of water.In actual use, more stable same of structure is made using simple structure
When it is easy to process.
And the connection type of valve rod 4 and valve body 1 between the two is that 4 bottom of valve rod is provided with flange 15, flange 1,5 against
On the valve body 1, and then valve rod 4 is made to be resisted against valve body 1, to being arranged valve rod 4 on sphere 2.In actual use process
In, it is easy to process while keeping structure more stable using simple structure.
In conjunction with Fig. 2, Fig. 3 and Fig. 4, it is known that in order to increase leakproofness, sealing element 1 is provided between valve body 1 and valve rod 4,
Specific connection type are as follows: valve rod 4 opens up fluted 14, while sealing element 1 is arranged in groove 14.
Valve body 1 is provided with the interconnecting piece 18 for connecting pipe simultaneously, and in order to increase leakproofness, interconnecting piece 18 and sphere
Sealing element 2 19 is provided between 2 between sphere 2 and valve body 1.In short, the junction in all parts is all made of sealing element
Sealing, to prevent the outflow and entrance of water, keeps structure more stable.
It in conjunction with Fig. 1 and Fig. 4, specifically sees shown in Fig. 5,1 surface of valve body is provided with several reversed acanthoid chimbs 20, for connecting
And fixed -piping, it allows the water to more smooth the phenomenon that passing through and reduce water spray as far as possible.In actual use, it uses
Simple structure is easy to process while keeping structure more stable.
The specific work process of this programme is as follows:
The utility model is matched by polygonal hole 5 with the valve rod 4 of polygon, realizes the rotary spacing of certain angle,
Pass through to realize limit and control the function of water flow compared to the method for one limited block of increase of more original use
The cooperation of limited block and valve rod limits to realize, which is simplified, and makes to make while structure is simpler stable to add
Work and installation are more convenient.
A kind of specific mode can are as follows: when valve rod 4 is located at rotating part 8, valve rod 4 is free to rotate, and works as valve rod 4
When being connected on limit seamed edge 9, then valve rod 4 is hindered, and then stops travelling forward, but can counter motion.Therefore pass through valve
Bar 4 is connected on limit seamed edge 9, to hinder the movement of valve rod 4, realizes the rotary spacing of certain angle, and then limit valve
The range that bar 4 rotates, so that the flow velocity of water and the range of flow are limited, while keeping structure more stable using simple structure
It is easy to process.
And the polygonal hole 5 in specific limit method is by symmetrical two planes and symmetrical two circular arcs herein
Face is formed, and corresponding to valve rod 4 is octagon, wherein being longer sides there are two side, in addition six sides are shorter, to be formed flat
Shape.It is released respectively by six shorter sides and plane with arc surface, to form the rotary spacing of certain angle.
Certainly only said a kind of shape here, i.e., polygonal hole 5 is quadrangle, while valve rod 4 is octagon, so
In addition to this other polygons be can also be, therefore this is only merely a kind of citing of more excellent mode.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model
Within the scope of.
