Abstract
An anti-misoperation ball valve relates to the technical field of ball valves and comprises a valve body, a valve rod and an operation handle. One end of the valve rod is placed outside the valve body and is connected with the operation handle to facilitate operation, and the other end of the valve rod penetrates through the valve body to be placed in the valve body. The anti-misoperation ball valve is characterized in that one end of the valve rod penetrating out of the valve body is further provided with a switch location piece with a lock hole and used for preventing misoperation, and a fixed hole corresponding to the lock hole is further arranged on the valve body. The anti-misoperation ball valve has the advantages that the switch location piece for limiting rotating angle is arranged on the valve rod, and a lock can be utilized to limit the rotating angle to be in 90 degrees, so that the valve body can only be in opening or closing state. Therefore, the anti-misoperation ball valve avoids misoperation and ensures safe production.
Description
Technical field
The utility model relates to the ball valve technical field, is specifically related to a kind of anti-misoperation ball valve.
Background technique
Ball valve is that a kind of use is made open-shut device with the spheroid of manhole, and spheroid rotates with valve rod, to realize the valve of switching motion.Be mainly used in blocking or connect the medium in pipeline, also can be used for adjusting and the control of fluid, also can close arbitrary passage simultaneously and two other passage is connected.
Valve in use, due to user's opening/shutting valve under the state of emergency of being everlasting, the operation that is easy to make a mistake causes unnecessary trouble.The most more complicated of the misoperation-proof mechanism of existing ball valve are used inconvenience, and are lost time.
In order to solve the deficiencies in the prior art, ensure safety in production, this case inventor is in conjunction with self experience, developed a kind of science rational in infrastructure, safe and reliable anti-misoperation ball valve.
The model utility content
The technical problem that the utility model solves is to provide a kind of anti-misoperation ball valve scientific and reasonable for structure.
The technical problem that the utility model solves realizes by the following technical solutions:
The anti-misoperation ball valve, comprise valve body, valve rod and operating grip, one end of described valve rod is placed in outside described valve body, and be connected with described operating grip, convenient operation, the other end penetrates described valve body and is placed in described valve body, it is characterized in that: an end that passes described valve body at described valve rod also is provided with one in order to prevent the switch location piece with lockhole of faulty operation, also is provided with the fixed hole corresponding with described lockhole on described valve body.
The upper end portion of described valve rod and the joint of described operating grip are the flat structural design, and the angle of swing of described switch location piece is defined between the 0-90 degree.
The beneficial effect that the utlity model has is: by arranging in order to limit the switch location piece of angle of swing on valve rod, and can utilize lockset with its angle of swing be limited to 90 the degree within, and then make valve body can only be in unlatching or closed condition, and avoid faulty operation, ensure safety in production.
Description of drawings
Fig. 1 is the utility model: the overall structure generalized section of anti-misoperation ball valve;
Fig. 2 is the utility model: the structural representation of the valve rod head of anti-misoperation ball valve;
Wherein: 1-valve body, 2-valve rod, 3-handle, 4-lockhole, 5-switch location piece, 6-fixed hole.
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.
Shown in Fig. 1-2, the anti-misoperation ball valve, comprise valve body 1, valve rod 2 and operating grip 3, one end of described valve rod 2 is placed in outside described valve body 1, and be connected with described operating grip 3, the joint of the upper end portion of described valve rod 2 and described operating grip 3 is the flat structural design, and convenient operation, the other end of valve rod 2 penetrate described valve body 1 and be placed in described valve body 1.An end that passes described valve body 1 at described valve rod 2 also is provided with one in order to prevent the switch location piece 5 with lockhole 4 of faulty operation, also is provided with the fixed hole 6 corresponding with described lockhole 4 on described valve body 1.Utilize lockset to pass lockhole 4 and fixed hole 6, and then within the angle of swing of switch location piece 5 can being limited to 90 degree, and then make valve body can only be in unlatching or closed condition, and avoid faulty operation, ensure safety in production.
Above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
