The valve rod that is installed on valve body, it is connected in three way cock;
The filler of being located at valve body top filler assembling cavity, is provided with filler upper press cover on the top of filler, and the bottom of described filler is provided with filler lower cover;
Be installed on valve body top and be installed with in the gland nut of filler upper press cover;
Be installed on the handle of valve rod upper end;
It is characterized in that, also comprise:
The self-locking fixing frame that is installed on valve body, it has stop pin spliced eye;
Be installed on the retainer nut of handle, its lower pin-and-hole Zhou Jing with a pin-and-hole and this pin-and-hole is greater than pin-and-hole Zhou Jing;
Be installed on retainer nut's stop pin, it is provided with annular protrusion near stop pin lower end position, and described lower pin-and-hole is provided with the Returnning spring that upper and lower end is resisted against respectively pin-and-hole top, annular protrusion;
Be installed on the stop pin spanner at stop pin top.
Described stop pin spanner is removably installed in stop pin by straight pin.
Described stop pin is partly provided with partial screw threads end near stop pin spanner, and this partial screw threads end is arranged with hexagonal locking nut.
Described self-locking fixing frame has the belled part and the U-shaped portion that is located at one end, belled part that are sheathed on valve body, and described stop pin spliced eye is arranged at the upper shell fragment of U-shaped portion.
Compared with prior art, the utlity model has following beneficial effect:
(1) can prevent threeway plug valve generation misoperation.
(2) because stop pin structure plays locking effect, prevent the disturbance of fed sheet of a media and spool is deflected, can be because of not the washing away or collide and cause handle to rotate of medium, and then improve the stability of valve working.
(3) Returnning spring can make stop pin in the situation that lacking external force lifting, automatically resets, and increases the convenience of operation.
Accompanying drawing explanation
Fig. 1 is threeway plug valve sectional structure schematic diagram.
Fig. 2 is threeway plug valve clipped structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, threeway plug valve, it has: bottom is provided with the valve body 2 of support 1, the three way cock that it has threeway medium runner and is installed on threeway medium runner intersection; The valve rod 3 that is installed on valve body, it is connected in three way cock; The filler 6 of being located at valve body top filler assembling cavity, is provided with filler upper press cover 7 on the top of filler, and the bottom of described filler is provided with filler lower cover 5; Be installed on valve body top and be installed with the gland nut 8 in filler upper press cover; Be installed on the handle 9 of valve rod upper end.
This threeway plug valve is also provided with preventing valve misoperation and the limit stoper that improves valve working stability, this limit stoper comprises: the self-locking fixing frame 4 that is installed on valve body, it has stop pin spliced eye, the lock mode of fixing frame can utilize gland nut to be installed with and lack under External Force Acting and be difficult for deflecting, when tightening gland nut, self-locking fixing frame is compressed and can pull under external force rotation; Be installed on the retainer nut 13 of handle, its lower pin-and-hole Zhou Jing with a pin-and-hole and this pin-and-hole is greater than pin-and-hole Zhou Jing; The stop pin 15 that is installed on retainer nut, it is provided with annular protrusion near stop pin lower end position, and described lower pin-and-hole is provided with the Returnning spring 14 that upper and lower end is resisted against respectively pin-and-hole top, annular protrusion; Be installed on the stop pin spanner 10 at stop pin top.
For ease of installation and the later maintenance of limit stoper, described stop pin spanner is removably installed in stop pin by straight pin 11.
