Description
Technical Field
The utility model relates to a stop valve case location technical field, concretely relates to case set nut of stop valve.
Background
The stop valve is also called as a stop valve, and belongs to a forced sealing type valve, when the valve is closed, pressure must be applied to a valve clack to force a sealing surface not to leak, and in order to ensure the normal use performance of the stop valve in the actual use process, the stable connection between a valve rod and a valve core of the stop valve is required to be ensured.
The valve rod and the valve core of the existing common stop valve are mainly fixed through a splicing mode, the valve rod and the valve core are easy to shake when a medium flows through the stop valve, and the valve core cannot accurately press an inner opening of the valve due to unreliable positioning between the valve rod and the valve core when the valve is closed, so that the use reliability of the stop valve is reduced, and the existing problem is solved by urgently needing a valve core positioning nut of the stop valve.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
In order to overcome prior art not enough, now provide a case set nut of stop valve, the valve rod of having solved current ordinary stop valve is mainly fixed through the mode of pegging graft with the case, and there is the medium to produce easily with the case when the medium flows in the stop valve and rocks, and often can lead to the case to accurately push down valve internal opening because of fixing a position unreliable between valve rod and the case when the valve is closed, reduces the problem of the reliability that the stop valve used.
(II) technical scheme
The utility model discloses a following technical scheme realizes: the utility model provides a case set nut of stop valve, including stop valve body and set nut, this internal valve rod that is provided with of stop valve, the mode that the valve rod bottom was pressed through the card is fixed with the case, the valve rod with the case is connected the position and has been connect soon set nut, the inboard shaping of set nut is threaded, the peripheral lateral wall middle part shaping of set nut has the spiral shell platform, keep away from on the set nut equal shaping in spiral shell platform top and below has the thread.
By adopting the technical scheme, the positioning nut is additionally arranged at the connecting part of the valve core and the valve rod, so that the valve core and the valve rod are not easy to shake when medium flows, the valve core and the valve rod can be well kept perpendicular when the valve is closed, the valve core can accurately press an inner opening of the valve when the valve is closed, the normal use state of the valve is ensured, and the valve is more reliable in use.
Further, the positioning nut is screwed with the valve rod through the threads.
By adopting the technical scheme, the valve rod can be reliably connected with the positioning nut.
Furthermore, the positioning nut is screwed with the valve core through the thread.
By adopting the technical scheme, the positioning nut can be reliably connected with the valve core.
Furthermore, the stop valve body, the valve rod and the valve core are the same as the common stop valve in the prior art in structure.
By adopting the technical scheme, the positioning nut can be ensured to be normally installed and used.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
the valve rod and the case of solving current ordinary stop valve mainly fix through the mode of pegging graft, have the medium stream in the stop valve to go out the valve rod and the case and produce easily and rock, and often can lead to the case can not accurately push down the interior opening of valve because of fixing a position unreliable between valve rod and the case when the valve is closed, reduce the problem of the reliability that the stop valve used, the utility model discloses an increase set nut at case and valve rod connection position, not only make case and valve rod difficult production rock when the medium stream is out of date, can make case and valve rod fine maintenance perpendicular when the valve is closed moreover, the case can accurately push down the interior opening of valve when guaranteeing to close, guarantee the normal use state of valve for the valve uses more reliable.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-2, the spool positioning nut of the stop valve in this embodiment includes a stop valve body 1 and a positioning nut 4, a valve rod 3 is disposed in the stop valve body 1, a spool 2 is fixed at the bottom end of the valve rod 3 by a clamping manner, the positioning nut 4 is screwed at a connection portion of the valve rod 3 and the spool 2, a thread 7 is formed at the inner side of the positioning nut 4, a screw platform 5 is formed at the middle portion of the peripheral side wall of the positioning nut 4, threads 6 are formed on the positioning nut 4, which are far away from the upper portion and the lower portion of the screw platform 5, by adding the positioning nut 4 at a connection portion of the spool 2 and the valve rod 3, the spool 2 and the valve rod 3 are not easy to shake during medium flow, the spool 2 and the valve rod 3 can be well kept perpendicular when the valve is closed, the spool 2 can accurately press an opening in the valve, the valve is more reliable to use.
As shown in fig. 1, in this embodiment, the positioning nut 4 is screwed to the valve rod 3 through the thread 7, so that the valve rod 3 can be reliably connected to the positioning nut 4, the positioning nut 4 is screwed to the valve element 2 through the thread 6, so that the positioning nut 4 can be reliably connected to the valve element 2, and the stop valve body 1, the valve rod 3 and the valve element 2 are all the same as those of a common stop valve in the prior art, so that the positioning nut 4 can be normally installed and used.
