Preferably, external screw thread is equipped on the lower half portion of valve rod linkage section.
It is had the beneficial effect that possessed by the utility model by making in satisfaction by nut set and valve stem sleeve split-type design
Under the premise of requiring, realizes and nut set is safeguarded or replaced in non-stop-machine situation, compact overall structure, behaviour
Make fast, to reduce the influence to operating system.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, a kind of electronic drain valve valve stem nut structure, including valve body clip 14, it is pushed up in valve body clip 14
Portion is equipped with perforation embedded with support lid 1, at support 1 center of lid, and the perforation is divided into 12 He of smooth section from top to bottom
Internal thread segment 13 is equipped with nut set 5 in smooth section 12, is connected with valve stem sleeve in 13 internal screw thread of internal thread segment, covers 5 in nut
It is interior equipped with the internal screw thread to match with valve rod external screw thread, it is small with the outer diameter of 13 position corresponding section of internal thread segment on nut set 5
In with the outer diameter of 12 position corresponding section of smooth section to accommodate valve stem sleeve；The valve stem sleeve is divided into 6 He of external thread section from top to bottom
Valve rod linkage section 9, the external thread section 6 are threadedly coupled with internal thread segment 13, and the internal diameter of external thread section 6 is greater than valve rod linkage section 9
Internal diameter and ring-shaped step is formed in valve stem sleeve, nut set 5 bottom end apical grafting on ring-shaped step；It is filled on support lid 1
Equipped with the positioning end cap 2 for clamp nut set 5, the positioning end cap 2 passes through circumferential multiple fastening bolts 7 and support lid
1 is detachably fixed connection.
For the ease of installation, disassembly and the positioning of nut set 5, end cap 3, the end cap 3 are integrally formed at 5 top of nut set
Outer diameter be greater than the internal diameter of smooth section 12, the upper annular notch for accommodating end cap 3 is equipped at the top of smooth section 12, in end cap
3 tops are around being circumferentially with multiple positioning grooves, around being circumferentially with multiple positioning matched with positioning groove on positioning end cap 2
Pawl 4.
In order to ensure valve stem sleeve is installed in place, it is equipped with and outwardly protrudes in the junction of external thread section 6 and valve rod linkage section 9
Baffle ring 11 is equipped with the lower annular notch 8 for accommodating baffle ring 11 in the bottom of internal thread segment 13, and baffle ring 11 presses against lower annular and lacks
It indicates to be installed in place when the top of mouth 8.
External screw thread 10 is equipped on the lower half portion of valve rod linkage section 9 simultaneously.
When the utility model is used, valve stem sleeve to be screwed in internal thread segment 13 inside valve body clip 14 first, then fill
Enter nut set 5, allow the bottom end apical grafting of nut set 5 on ring-shaped step, last fit on positions end cap 2, thus by 5 pressure of nut set
Tightly on support lid 1, valve rod is finally sequentially loaded into valve stem sleeve from bottom to top, in nut set 5, when nut set 5 goes wrong
