Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
As it is shown in figure 1, a kind of valve having current limliting and sealing excellent function, including valve body 1, valve body 1 is cylindrical knot
Structure, the symmetrical dovetail grooves 2 offering two and the connection of valve body 1 outer surface on the inwall of valve body 1, valve body 1 outer surface symmetry connects
Having the water outlet connecting tube 3 connected respectively and water inlet connecting tube 4 with two dovetail grooves 2, the internal sleeve of valve body 1 is connected to threaded rod 5, spiral shell
Rasp bar 5 is hollow structure, and the top of threaded rod 5 passes thread groove that valve body 1 offers and connection has rotating disk 6, and rotating disk 6 top
Center connect and have rotary column 7, the bottom of rotary column 7 connects the first screw rod 8, and it is internal that the end of the first screw rod 8 inserts threaded rod 5
And be connected with the intracavity bottom of threaded rod 5 by rotating shaft 9, the inside of threaded rod 5 is provided with two the second screw rods 10, two the second spiral shells
Bar 10 lays respectively at the front side of the first screw rod 8 and rear side and is all threaded engagement with the first screw rod 8, deviating from of two the second screw rods 10
End is respectively connected with trapezoid block 11, and trapezoid block 11 deviates from one end of the second screw rod 10 and passes threaded rod 5 and extend in dovetail groove 2,
In trapezoid block 11 can be inserted into dovetail groove 2, and by the different depth of regulation reeve dovetail groove 2, thus reach regulation limit
The size of stream, and after trapezoid block 11 is fully inserted into dovetail groove 2 so that water outlet connecting tube 3 and water inlet connecting tube 4 seal, by
In trapezoid block 11 go to the bottom and angle between waist is 15 degree, trapezoid block 11 matches with dovetail groove 2 so that sealing effectiveness is more
Add excellence.
As shown in Figure 1-2, the inside of rotary column 7 offers article putting groove 12, and the top of rotating disk 6 offers and connects with article putting groove 12
Draw-in groove 13, be provided with the 3rd screw rod 14 in article putting groove 12, the end of the 3rd screw rod 14 extends in draw-in groove 13, sets in article putting groove 12
Having and the 4th screw rod 15 of the 3rd screw rod 14 screw-threaded engagement, one end of the 4th screw rod 15 passes rotary column 7 and connection has brake posts 16,
The quantity of draw-in groove 13 is eight, and eight draw-in grooves 13 are opened in the top of rotating disk 6, and eight draw-in grooves 13 with the form of annular array
Being respectively positioned on the underface of rotary column 7, a length of four centimetres of article putting groove 12, a length of 35 centimetres of the 3rd screw rod 14, when
After three screw rods 14 take in article putting groove 12, the 3rd screw rod 14 completely disengages from draw-in groove 13, will not stop the rotation of rotary column 7, the 3rd spiral shell
After bar 14 sticks in draw-in groove 13, reach the effect of fixing rotary column 7, it is possible to coordinate the current limliting of valve further so that the limit of valve
Stream effect is more excellent.
When the present invention seals, first rotate rotating disk 6, threaded rod 5 be screwed in valve body 1, rotate rotary column 7 so that
First screw rod 8 rotates and passes through screw thread and promotes two the second screw rods 10 to move, and in trapezoid block 11 is advanced dovetail groove 2, until
Turn motionless, a draw-in groove 13 now must be had to dock with article putting groove 12, then rolling brake post 16, rotated also by the 4th screw rod 15
Promote the 3rd screw rod 14 decline and extend in draw-in groove 13 with screw thread, fix rotary column 7, reach to seal.
When the present invention carries out current limliting, first rotate rotating disk 6, threaded rod 5 be screwed in valve body 1, rotate rotary column 7 so that
