Abstract
The utility model discloses a locking-type ball valve. The locking-type ball valve comprises a valve body, a valve plug which is arranged in the valve body, and a valve rod; one end of the valve rod extends into the valve body and is linked and matched with the valve plug, and the other end of the valve rod extends out of the valve body and is fixed with a handle; the locking-type ball valve is characterized in that: the upper part of the valve body is fixed with two locking plates which are vertical to each other and are positioned at the opening and closing positions of the handle; and the handle can lock the locking plates. The handle can be locked with the locking plates at the opening and closing positions, and is high in operation reliability, so the safety accident or unnecessary loss which is caused by misoperation on the handle can be prevented.
Description
Technical field
The utility model relates to a kind of ball valve, especially a kind of ball valve that can lock in the opening and closing position.
Background technique
Ball valve is a kind of open-shut device, is driven by valve rod, and around the valve that the axis of valve rod rotates, is mainly used in the medium that blocks or connect in the pipeline, also can be used for the adjusting and the control of fluid.Ball valve has and revolves the action that turn 90 degrees, and open-shut device is a spheroid, manhole or passage is arranged through its axis.
Existing ball-valve structure generally comprises valve body, spool, valve rod and operating device such as handle, is provided with the stream chamber in the valve body, and spool places in the stream chamber, and valve rod stretches in the valve body and is linked with spool, and its outer end is stretched out valve body and is fixedly connected with handle.But this valve; The locking framework that operating devices such as its handle do not have to be fit to cooperates to prevent that the misoperation that opens and closes from appearring in handle; As because user's carelessness or children's curiosity etc.; The valve open that should not open may cause fatal security incident or unnecessary loss thus.
The model utility content
The locking-type ball valve that the utility model technical problem to be solved provides and a kind ofly can under the keying state, lock, operational reliability is high.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of locking-type ball valve, comprise valve body, and be arranged on the spool in the said valve body; And valve rod; One end of said valve rod stretches in the said valve body and is linked with said spool, and the other end of said valve rod stretches out said valve body and handle is fixed, and it is characterized in that; Said valve body top is fixed with two mutually perpendicular locking plates that lay respectively at said handle opening and closing position, and said handle can lock with said locking plate.
The end of said locking plate is provided with the locking plate lockhole, and the position of the corresponding said locking plate lockhole of said handle is provided with the handle lockhole, can handle and locking plate be fixed through this lockhole thus, to avoid handle by misoperation.
In a preferred embodiment of the utility model, said handle and said locking plate are by the pin locking of passing said locking plate lockhole and said handle lockhole.
Said locking plate is one-body molded.
Compared with prior art; The advantage of the utility model is: the opening and closing position at handle is respectively equipped with locking plate; Lockhole is offered in relevant position at handle and locking plate; Make handle can both lock with locking plate, thereby can prevent that handle from being caused security incident or unnecessary loss by misoperation two positions.
Description of drawings
Fig. 1 is the schematic representation of the ball valve of the utility model;
Fig. 2 is that the A-A of Fig. 1 is to partial sectional view;
Fig. 3 is the schematic representation of the locking plate of the utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, a kind of locking-type ball valve comprises valve body 1, is provided with stream chamber 2 in the valve body 1, and spool 3 places in the stream chamber 2, and an end of valve rod 4 stretches in the valve body 1 and with spool 3 and is linked, and the other end of valve rod 4 stretches out valve body 1 top and is fixedly connected with handle 5.
Valve body 1 top is provided with that 6, two locking plates 6 of two locking plates are one-body molded, orthogonal, as shown in Figure 3, and the common ends 61 of locking plate 6 is fixed on valve body 1 top, prevents that relative valve body 1 from rotating.
A locking plate 6 is positioned at the enable possition of handle 5,6 closed positions that are positioned at handle 5 of another locking plate, and the end of locking plate 6 is provided with locking plate lockhole 62, and the position of corresponding locking plate lockhole 62 is provided with handle lockhole 51 on the handle 5.When needs are opened ball valve flowing medium are passed through; Pulling handle 5 is to the enable possition; At this moment; Locking plate lockhole 62 on the locking plate 6 on handle lockhole 51 on the handle 5 and the enable possition is in same position, thereby can pass handle lockhole 51 and locking plate lockhole 62 locks handle 5 and locking plate 6 through pin, padlock etc., prevents thus to be closed by misoperation at this position handle 5.Same; When needs are closed ball valve when stoping flowing medium to pass through; Pulling handle 5 is to closed position, and at this moment, handle lockhole 51 on the handle 5 and the locking plate lockhole 62 on the locking plate 6 on the closed position are in same position; Can pass through pin, padlock etc. with handle 5 and locking plate 6 lockings, prevent thus to be opened by misoperation at this position handle 5.
The above is merely the preferred implementation of the utility model; Should be pointed out that for those of ordinary skill in the art, do not breaking away under the principle prerequisite of the utility model; Can also make various deformation and improvement, this also should be regarded as the protection domain of the utility model.
