Abstract
The utility model relates to the technical field of valves, in particular to an internal thread locking valve which comprises a nut and a valve body. A ball is arranged in the valve body. A sealing ring is arranged between the ball and the valve body. The upper portion of the valve body is provided with a valve rod connected with the ball in a matched mode. The upper portion of the valve rod is matched and provided with a locking valve handle in a covering mode. The locking valve handle comprises a handle body and a handle head. The handle head is provided with a triangular cavity. The upper portion of the valve rod is provided with a triangular boss matched and connected with the triangular cavity in a sleeved mode. Triangular structures matched and connected in the sleeved mode are arranged on the upper portion of the handle head and the upper portion of the valve rod, and therefore the internal thread locking valve is different from a common spanner. In addition, the handle head comprises a notch lantern ring and an unlocking ring, the notch ring is used for limiting the rotation angle, the unlocking ring is matched with the valve rod in a triangular mode so that the ball and the valve body can be opened and closed, and the anti-theft purpose is achieved through matching of the notch lantern ring and the unlocking ring.
Description
Technical field
The utility model relates to valve technology field, particularly internal thread locking-valve.
Background technique
At present, valve mechanism of the prior art generally comprises valve body, is arranged at spool and valve rod in valve body.When use, by the handle on rotating valve, band ovable valve stem, spool action, thereby reach the flow channels of closing or opening in valve body, but valve applications of the prior art is in gas pipe line time, the valve rod on valve is easy to be opened by common spanner, operation that can be simple and relax, thus owner is caused to economic loss.
Model utility content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of and prevents that common wrench from opening and the internal thread locking-valve of good anti-theft effect.
For achieving the above object, the utility model is by the following technical solutions: internal thread locking-valve, comprise valve body, in valve body, be provided with spheroid, between spheroid and valve body, be provided with seal ring, valve body top is provided with the valve rod being connected with spheroid, the cooperation of described valve rod top is covered with locking-valve handle, locking-valve handle comprises handle body and handle head, and handle head offers triangle cavity, and described valve rod top is provided with the triangle boss that coordinates socket with triangle cavity.
Wherein, described handle head comprises the unlocking link of being located at the outside breach collar and being located at middle part, in unlocking link, be provided with described triangle cavity, triangle cavity comprises two straight flanges that become angle, and the straight flange of triangle cavity and unlocking link and the breach collar are one-body molded.
Wherein, between described valve rod and spheroid, be provided with "O"-ring, one end of valve body is provided with housing, and the other end of valve body is connected with fittings body.
The utility model beneficial effect is: the utility model comprises valve body, in valve body, be provided with spheroid, between spheroid and valve body, be provided with seal ring, valve body top is provided with the valve rod being connected with spheroid, the cooperation of described valve rod top is covered with locking-valve handle, locking-valve handle comprises handle body and handle head, and handle head offers triangle cavity, and described valve rod top is provided with the triangle boss that coordinates socket with triangle cavity; The utility model is by being arranged to handle head and valve rod top the leg-of-mutton structure that coordinates socket, be different from so common spanner, in addition, handle head of the present utility model comprises the breach collar and unlocking link, landolsring is for limiting the angle of rotation, and unlocking link coordinates with valve rod triangle and make spheroid and valve body folding, the cooperation of the breach collar and unlocking link reaches antitheft object.
