Abstract
The utility model discloses a ball valve capable of being locked in a closed state. The ball valve comprises a valve body, a valve spool, a valve stem and a handle. The valve spool is positioned in the valve body, a sealing ring is arranged between the valve stem and the valve body, the inner end of the valve stem is connected with the valve spool, the outer end of the valve stem is connected with the handle, a strut is fixedly connected to the front end of the handle, the handle and the strut are positioned on the same axis, a pinch plate is hinged on the strut, a fixing seat is protruded on the outer wall of the valve body, a groove matched with the pinch plate is arranged on the fixing seat, and the handle can be fastened in the groove on the fixing seat via the pinch plate to be locked when the ball valve is in the closed state. The ball valve is simple in structure and convenient to use, and the pinch plate can be matched with the groove when the ball valve is in the closed state, so that the handle is locked, an operator is prevented from being accidentally in contact with the handle or accidentally operating the handle to open the ball valve to cause safety accidents, and the operational safety is effectively guaranteed.
Description
Technical field
The utility model relates to a kind of ball valve, is specially a kind of lockable ball valve in off position the time.
Background technique
Ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.Ball valve is mainly used to make cut-out, distributes and change medium in pipeline flow direction, it only need to just can be closed tightly with the operation of 90-degree rotation and very little moment of rotation.And existing ball valve if the worker runs into handle or misoperation because of carelessness, can make ball valve arbitrarily open when some factory's pipelines use, open pipe, and then can cause beyond thought security incident, cause adverse consequences.
The model utility content
The purpose of this utility model provides a kind of lockable ball valve in off position the time, to solve ball valve traditional in the prior art when some factory's pipelines use, if the worker runs into handle or misoperation because of carelessness, ball valve is arbitrarily opened, open pipe, and then can cause beyond thought security incident, cause the problem of adverse consequences.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of lockable ball valve in off position the time, include valve body, spool, valve rod and handle, described spool is positioned at valve body, be provided with seal ring between described valve rod and the valve body, the inner of described valve rod is connected with spool, the outer end of described valve rod is connected with handle, it is characterized in that: the front end of described handle is fixedly connected with handle and is positioned at pole on the same axis, be hinged with buckle on the described pole, be raised with fixed base on the described valve outer wall, described fixed base is provided with the groove that matches with buckle, described handle when the ball valve closed condition can by in the groove of buckle fastening on fixed base to lock.
Described a kind of lockable ball valve in off position the time, it is characterized in that: described pole and handle are integrated casting.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to use, employing arranges buckle at handle, fixed base is set on the valve outer wall and the design of the groove match with buckle is set at fixed base, in the time of can making ball valve in off position by buckle and groove fit with handle locking, in order to avoid the operator runs into handle or misoperation because of carelessness, cause ball valve to be opened and the initiation security incident, effectively guaranteed job security.
