Abstract
The utility model relates to a special angle valve, which comprises a valve body, a valve rod and a supporting frame, wherein, the valve body is provided with a liquid inlet and a liquid outlet, and the valve body is in threaded connection with the supporting frame; the valve rod is arranged between the valve body and the supporting frame, one end of the valve rod is connected with a hand wheel, and the other end is fixedly connected with a conical valve core; the outer part of the valve rod which is arranged at the lower part of the threaded connecting end between the valve body and the support frame is in sleeve joint with a sealing ring A, a sealing ring B and an inverted closing part; the sealing ring A and the sealing ring B are matched with each other in a sealing way by a conical surface; a convex column which is formed on the inverted closing part is clamped with the sealing ring B; a sealing ring C which is matched with the valve core in a sealing way is tightly matched in the valve body, and the lower end part of the sealing ring C is abutted on the wall of a pipe column at the liquid inlet end of the valve body. The utility model overcomes the problems that an existing special angle valve is easy to leak in using, and the sealing ring which is matched with the conical valve core is easy to shed. The utility model enhances the sealing performance of the special angle valve and the reliability of the assembly of the sealing ring C. The utility model has the advantages of simple structure, no leakage, and rapid and fast opening and closing.
Description
Affiliated technical field
The utility model relates to a kind of Special angle valve.
Background technique
Special angle valve is a kind of machinery of control media transmission in pipe-line system; traditional Special angle valve; its sealing configuration is very unreasonable; through regular meeting leakage phenomenon appears in use; the seal ring that matches with taper valve core particularly; assembling between itself and valve body is the close-fitting structure only, and reliability is low, also obscission can occur under the pressure of taper valve core.
Summary of the invention
Unreasonable in order to overcome in the prior art sealing configuration of Special angle valve, the seal ring and the assembly reliability between valve body that in use easily leak, match with taper valve core are low, the problem that comes off easily.The utility model provides a kind of Special angle valve, and the sealing of this Special angle valve is tight, and the assembling of the seal ring that matches with taper valve core is solid and reliable.
The technological scheme that its technical problem that solves the utility model adopts is: comprise valve body, valve rod and support, valve body is provided with liquid entering hole and liquid outlet, valve body and support are threaded, an end that is arranged on the valve rod in valve body and the support is connected handwheel, the affixed taper valve core of the other end, socket seal ring A outside the valve rod below valve body and support threaded ends, seal ring B and fall to close, seal ring A becomes conical surface seal to cooperate with seal ring B, shut and form projection and seal ring B clamping, the seal ring C close-fitting that cooperates with seal spool is in valve body, and its underpart is resisted against on the tubing string wall of valve body liquid feeding end.
The utility model is by above-mentioned design, improved the sealability of Special angle valve and the reliability of seal ring C assembling greatly, have simple in structure, do not leak, open and close advantage efficiently rapidly.
Description of drawings
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model;
Embodiment
As shown in the figure, the utility model comprises valve body 1, valve rod 2 and support 3, valve body 1 is provided with liquid feeding end 12 and outlet end 13, valve body 1 and support 3 are threaded, an end that is arranged on the valve rod 2 in valve body 1 and the support 3 is connected handwheel 4, the affixed taper valve core 5 of the other end, socket seal ring A6 outside the valve rod 2 below valve body 1 and support 3 threaded ends, seal ring B7 and close 8, seal ring A6 becomes conical surface seal to cooperate with seal ring B7, close and form projection 9 and seal ring B7 clamping on 8, the seal ring C10 close-fitting that is sealed and matched with spool 5 is in valve body 1, and its underpart is resisted against on the tubing string wall 11 of valve body 1 liquid feeding end 12.Under user mode, the medium that is entered by liquid feeding end 12 enters in the valve body 1 after by seal ring C10, and by outlet end 13 discharges, because seal ring A6, the seal ring B7 of valve rod 2 outer sockets and close 8 effect, can improve the sealability of Special angle valve, and behind seal ring C10 and valve body 1 close-fitting and be resisted against on the tubing string wall 11 of valve body 1 liquid feeding end 12, make that seal ring C10 is also unlikely under the big pressure that spool 5 is closed from valve body 1, to come off.
