Abstract
The utility model relates to an internal-thread spherical valve, which comprises a valve body with internal threads, a valve seat, a spherical valve core, a valve rod linked with the valve core, and a handle, wherein a through hole perpendicular to the valve rod is formed at the upper end of the valve rod, and screw threads are formed at the cylindrical installation end of the handle; and the installation end penetrates through the through hole and is fastened through bolts. The grip part of the handle adopts a Z-shaped structure. The utility model has the advantages as follows: firstly, force for fastening the handle is transferred to the screw threads at the installation end of the handle by arranging the through hole for mounting the handle on the valve rod, so as to avoid harms caused by the valve rod; secondly, the grip part of the handle is designed to be Z-shaped, so as to enable a palm to keep a certain distance with a pipeline when the handle is rotated, and injures caused to hands due to the friction between the palm and the hand can be avoided.
Description
Technical field
The utility model relates to a kind of ball valve, relates in particular to a kind of internal thread ball valve.
Background technique
The single piece type internal thread ball valve of smart casting is a kind of ball valve of having many uses in the world at present, two ends of valve body has internal thread, be provided with spheroid spool and valve seat in the valve body, valve rod and spheroid spool are connected, valve rod upper end connects handle, realizes control that ball valve is opened/closed by handle with sleeve, and prior art is offered a rectangular opening at the connecting end of handle usually when handle is installed, again the valve rod upper end is inserted in this rectangular opening, uses nut screwing clamping at last.As the patent No. is 98224837.7, denomination of invention is the model utility of " single piece type internal thread ball valve ", its handle be flat and by nut check in valve rod upper end, though this structure is saved cost, easy for installation, but its defective is also comparatively obvious: because the length of valve rod upper end (promptly stretching out the part of valve body) is generally shorter, adopt nut to determine handle thinner usually the mounting type of handle locking in the valve rod upper end, in long-term using process, the mounting hole easy deformation of handle, and can produce big gap between the valve rod, be difficult for controlling.In addition, adopt the wayward dynamics of mode of locking nut, if firmly kick the beam, then can't set lever; If firmly overweight, because nut is installed on the screw thread of valve rod, this damages the screw thread of valve rod again easily.
The model utility content
For this reason, technical problem to be solved in the utility model is unreasonable structure between internal thread ball valve handle and the valve rod, easily produces loosening and problem such as infringement threaded stem, provides a kind of simple in structure, the internal thread ball valve of being convenient to install.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of internal thread ball valve, comprise tapped valve body, valve seat, spheroid spool, with the valve rod and the handle of spool interlock, described valve rod upper end offers the through hole perpendicular to valve rod, the mounting end of described handle is cylindric and offers screw thread, and described mounting end passes described through hole and passes through bolton.
Further, described handle is the zigzag structure, and this structure makes that the perpendicular distance of the hand holding end of handle and pipeline is far away, avoids rubbing between the hand and pipeline when handle with sleeve, produces injury.
Technique scheme of the present utility model has the following advantages compared to existing technology:
1, improves by transposition, on valve rod, offer the through hole that handle is installed, make the strength of fastening handle transfer on the screw thread of handle mounting end, avoid valve rod is produced injury.Even if after long-term the use, it is big that the gap between valve rod and the handle becomes, and also can solve by the mode of changing handle.
2, the handle with handle is designed to zigzag, and palm can produce certain span with pipeline when making handle with sleeve, avoids between the two that the adversary produces injury because friction takes place.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the structural representation of internal thread ball valve of the present utility model.
Embodiment
As shown in Figure 1, internal thread ball valve described in the utility model, comprise tapped valve body 1, valve seat 2, spheroid spool 3, with the valve rod 5 and the handle 6 of spool 3 interlocks, described valve rod 5 upper ends offer the through hole perpendicular to valve rod 5, the mounting end of described handle 6 is cylindric and offers screw thread, and described mounting end passes described through hole and fastening by bolt 4.Described handle 6 is the zigzag structure, and this structure makes that the perpendicular distance of the hand holding end of handle 6 and pipeline is far away, avoids rubbing between the hand and pipeline when handle with sleeve 6, produces injury.
Obviously, the foregoing description only is for example clearly is described, and is not the qualification to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation of being extended out thus or change still are among the protection domain of the utility model creation.
Claims (2)
