This utility model is a kind of stop valve stopping means, it is characterized in that, including handle, limited block, securing member, valve body, valve rod, described valve rod is provided with groove, limited block protrudes cylindricality by bottom and is connected with stem groove, described valve stem sleeve is at valve body inner ring, and be connected with body top female thread by screw thread, described securing member is enclosed within valve rod outer ring, securing member lower end female thread is connected with valve body upper external screw thread fastening, the length that described limited block lower plane moves when being moved downward to dam with valve rod to the length of plane on securing member is equal, described handle is threaded connection with valve rod, and be connected with valve rod at handle and local again to be fixed by welding.Stop valve is when swing handle dams, and the valve body contacted with stem bottom can be protected by the stopping means being provided with stem bottom, it is to avoid valve rod that valve rod moves and causes and the damage of valve body; extend stop valve service life; and limited block is detachable, easy to use, can repeatedly utilize.
Description
Technical field
This utility model relates to stop valve technical field, particularly relates to a kind of stop valve stopping means.
Background technology
Stop valve, because of its simple in construction, easy to use is extensively liked by everybody, cut-off through commonly used valve as one
Valve is the most all by swing handle thus the effect moving up and down circulation and the cut-off reaching fluid of band ovable valve stem, but
Current most stop valve does not set stopping means, and valve rod can infinitely move down, and easily causes contacting with stem bottom
The damage of valve body and stem bottom, affect the service life of stop valve.
Summary of the invention
This utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of stop valve stopping means.
This utility model for achieving the above object, by the following technical solutions: a kind of stop valve stopping means, its feature exists
In, including handle, limited block, securing member, valve body, valve rod, described valve rod is provided with groove, and limited block protrudes post by bottom
Shape is connected with stem groove, and described valve stem sleeve is at valve body inner ring, and is connected with body top female thread by screw thread, described
Securing member is enclosed within valve rod outer ring, and securing member lower end female thread is connected with valve body upper external screw thread fastening.
The length that described limited block lower plane moves when being moved downward to dam to the length of plane and valve rod on securing member
Spend equal.
The place that described handle is connected with valve rod is provided with screw thread, is threaded connection, and is connected ground at handle with valve rod
Side is fixed again by welding.
The beneficial effects of the utility model are: this utility model is provided with stopping means on valve rod, carry out at swing handle
When damming, the valve body contacted with stem bottom can be protected with stem bottom, it is to avoid valve rod that valve rod moves and causes and
The damage of valve body, extends stop valve service life, and limited block is detachable, easy to use, can repeatedly utilize.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model；
In figure: 1-handle；2-limited block；3-securing member；4-valve body；5-valve rod；
It is described in detail referring to the drawings below with reference to embodiment of the present utility model.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of stop valve stopping means, it is characterised in that include handle 1, limited block 2, securing member 3, valve
Body 4, valve rod 5, described valve rod 5 is provided with groove, and limited block 2 protrudes cylindricality by bottom and is connected with valve rod 5 groove, described
Valve rod 5 is enclosed within valve body 4 inner ring, and is connected with valve body 4 top female thread by screw thread, and described securing member 3 is enclosed within outside valve rod 5
Circle, securing member 3 lower end female thread is connected with valve body 4 upper external screw thread fastening.
Described limited block 2 lower plane moves when being moved downward to dam with valve rod 5 to the length of plane on securing member 3
Length is equal, can protect valve rod and valve body, can fully realize again the effect dammed simultaneously.
The place that described handle 1 is connected with valve rod 5 is provided with screw thread, is threaded connection, and at handle 1 with valve rod 5 even
Ground connection side is fixed again by welding, it is to avoid the handle caused in handle rotation process comes off.
