Abstract
A novel ball valve comprises a valve body, a ball-shaped valve core installed in the valve body, a valve rod connected with the ball-shaped valve core, and a handle installed at the upper end of the valve rod, wherein a lug boss used for limiting the valve rod in a guiding hole of a right valve body is arranged at the lower part of the valve rod, a connecting part of the valve rod and the handle is a flat structure, and the handle is provided with a locking device. The ball valve has the advantages that the installation of the valve rod is reliable and stable, and the handle is not liable to dislocate, and can be used for locking a position.
Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of easy to use and reliable ball valve.
Background technique
In industrial or civilian infrastructure, utilize the line transportation medium usually, wherein since pressure or variation of temperature to regulate pipeline, use controlling mechanism for regulating flow in pipeline, ball valve especially is to guarantee the best operating conditions and the safety of working environment.
Ball valve adopts a spheroid that has through hole to be installed in valve inner usually, rotation by spheroid realizes closing and opening, because the frictional ratio between spheroid and the valve body is bigger, so, the handle of conventional ball valve is easy to occur inconsistent phenomenon, causes the on off state and the valve of handle indication inconsistent; The stability of valve rod is not good, and pressurized flies out easily; Handle misoperation may occur when switch, especially when standard-sized sheet or complete shut-down, handle can not lock, often owing to reasons such as vibrations are shifted.
The model utility content
The purpose of this utility model is to provide a kind of valve rod that reliable and stable, handle is installed to be difficult for producing dislocation and ball valve that can locked position.
For achieving the above object, the utility model by the following technical solutions.
A kind of ball valve comprises valve body, and described valve body comprises left valve barrel and the right valve barrel that utilizes bolt to connect as one; The ball-type spool, described ball-type spool is installed in valve inner; The space that valve rod, described valve rod pass between right valve barrel top guide hole, valve rod and the guide hole utilizes packing seal, and this valve rod lower end is connected with the ball-type spool; And the handle that combines with the valve rod upper end; Its notable feature is: described stem lower portion is provided with valve rod is limited to boss in the right valve barrel guide hole, and the connecting part of described valve rod and handle is flat type structure, and described handle is provided with locking device.
As a kind of improvement, the boss of described valve rod and the junction plane of right valve barrel are provided with pad.
As a kind of improvement, described locking device is the location piece that is welded on handle and the valve body.
As further improvement, offer positioning hole on the described location piece, location piece relies on the cooperation of positioning hole to lock.
In addition, for the shortcoming of the easy corrosion and damage of spool that overcomes conventional ball valve, ball-type spool of the present utility model adopts the Austenitic Stainless Steel member.
Owing to adopt above technological scheme, the utlity model has following beneficial effect:
1, the boss of valve rod lower end can position valve rod, makes it also to be difficult for flying out under high-pressure situations, and is reliable and stable;
2, valve rod utilizes flat type structure to combine with handle, and difficult the dislocation guarantees that the on off state of handle indication is consistent with valve;
3, the locking device of handle setting can guarantee that handle is not shifted with the handle locking when valve wide open or complete shut-down.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 and Figure 2, a kind of ball valve comprises valve body 1, and described valve body 1 comprises left valve barrel 11 and the right valve barrel 12 that utilizes bolt 13 to connect as one; Ball-type spool 2, described ball-type spool 2 is installed in valve body 1 inside, adopts the Austenitic Stainless Steel member; Valve rod 3, described valve rod 3 pass right valve barrel 12 top guide holes and adopt packing seal, and these valve rod 3 lower ends are connected with ball-type spool 2; And the handle 4 that combines with valve rod 3 upper ends; Its notable feature is: described valve rod 3 bottoms are provided with valve rod 3 are limited to boss 31 in right valve barrel 12 guide holes, boss 31 is provided with pad 32 with the junction plane of right valve barrel 12, described valve rod 3 is flat type structure 33 with the connecting part of handle 4, described handle 4 is provided with locking device, this locking device is the location piece 41 that is welded on handle 4 and the valve body 1, offer positioning hole 42 on the location piece 41, location piece 41 relies on the cooperation of positioning hole 42 to lock.
Below only be that of the present utility model for example protection domain of the present utility model is as the criterion with the content of claim, any based on modification of the present utility model all within protection domain of the present utility model.
