Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-5, the present embodiment discloses a ball valve for a gas pipeline, which includes a pipe body 1, a rotatable ball valve 2 is arranged in the pipe body 1, a connecting pipe 3 is arranged on the pipe body 1, a valve rod 4 fixedly connected to the ball valve 2 is arranged in the connecting pipe 3, one end of the connecting pipe 3 away from the ball valve 2 is rotatably connected to an installation ring 5, a handle 6 capable of swinging up and down is hinged to the installation ring 5, a connecting groove 7 is arranged on the handle 6, and a connecting block 8 in inserting fit with the connecting groove 7 is arranged on an end surface of the valve rod 4 away from the ball valve; a locking mechanism 9 is also arranged between the mounting ring 5 and the connecting pipe 4.

The locking mechanism 9 comprises a lock groove 91 arranged on the mounting ring 5, an elastically resettable lock column 92 is horizontally connected in the lock groove 91, and a lock hole 93 which is in plug-in fit with the lock column 92 is formed in the peripheral side of the connecting pipe 4; the handle is characterized by further comprising a control groove 94 arranged on the mounting ring 5, the control groove 94 and the lock groove 91 are perpendicular to each other and are communicated, an unlocking rod 95 is elastically connected in the control groove 94, and when one end of the handle 6 swings downwards, the unlocking rod 95 is pressed downwards; the unlocking rod 95 is provided with a tapered groove 96, and the tapered groove 96 is used for separating the lock cylinder 92 from the lock hole 92.

When the valve is in a closed or open state, as shown in fig. 4-5, at this time, the connecting groove 7 on the handle 6 swings upward under the action of the coil spring and the rotating shaft, so as to be separated from the connecting block 8, at this time, one end of the handle 6 is separated from the unlocking rod 95, the unlocking rod 95 slides upward under the action of the spring, and during the moving process of the sliding unlocking rod 95, the tapered groove 96 arranged above the sliding unlocking rod 96 abuts against the lock column 92 in the lock groove 91, and moves the lock column 92 toward the lock hole 93, so that the mounting ring 5 and the connecting pipe 3 are clamped with each other through the lock column 92, and the locking of the mounting ring 5 is realized; at this time, the handle hinged to the mounting ring 5 cannot be rotated, so that the valve stem 4 cannot be rotated by an external force.

When valve rod 4 control valve opens or closes when needs rotate, as shown in fig. 1-3, the user swings handle 6 downwards this moment, spread groove 4 on handle 6 can with the connecting block 8 mutual block on the valve rod 4, and handle 6 front end can push down unblock pole 95, unblock pole 95 pushes down and can drive tapered groove 96 decline, tapered groove 96 lies in after lock post 92 aligns, lock post 92 can move to tapered groove 96 under the effect of spring, thereby break away from lockhole 93, realize removing the locking between collar 5 and the connecting pipe, at this moment, the user is rotating the handle, can drive the valve rod and rotate, thereby can control ball valve 2 and rotate, realize opening and close of valve.

And, the lockhole distributes in the week side of connecting pipe 4, consequently can realize the locking of a plurality of angles of valve rod, and the practicality is better.

In this embodiment, the mounting ring 5 is further symmetrically provided with guide plates 10 located on two sides of the unlocking rod 95, and the guide plates 10 are used for guiding the end of the handle 6 to abut against the unlocking rod 95; the guide plate 10 can more conveniently allow one end of the valve rod to abut against the lock release lever 95.

In this embodiment, connecting block 8 is rectangular shape and the cross-section is trapezoidal setting, 7 shapes of spread groove rather than the phase-match, this structure lets the cooperation between connecting block 8 and the spread groove 7 inseparabler, has reduced the clearance between the cooperation of connecting block 8 and spread groove 7, lets the user when rotating, can let the response speed of valve rod faster.

In this embodiment, the length of the connecting groove 7 is greater than that of the connecting block 8.

In this embodiment, the handle 6 is connected to the mounting ring 5 through a rotating shaft, and a coil spring is disposed on the rotating shaft.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
