Abstract
The utility model discloses a manual control ball valve which comprises a valve body (4), a valve (8) and a valve rod (3). The valve (8) is installed inside an inner cavity of the valve body (4). The valve rod (3) is connected with the valve (8). The valve body (4) comprises a water inlet cavity (10) and a water outlet cavity (9). A handle (2) is connected with one end, extending out of the valve (8), of the valve rod (3) and fixed through a gland nut (1). A dovetail groove (7) is arranged at one end, connected with the valve (8), of the valve rod (3). A groove (5) in fit with the dovetail groove (7) is arranged in the valve (8). Due to the fact that the dovetail groove (7) is arranged at one end, connected with the valve (8), of the valve rod (3), and the groove (5) in fit with the dovetail groove (7) is arranged in the valve (8), the manual control ball valve is capable of enlarging a stressed area, enabling connection between the valve rod and the valve to be firm and reliable, prolonging service life, being simple in structure, novel in design, and practical.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of manual control ball valve.
Background technique
Valve is a kind of device is used for controlling flow in pipeline equipment, plays very important effect in pipe fittings, and existing valve comprises valve pipe, valve body and Joystick; The valve pipe is communicated with water pipe, and valve body to be positioned at the valve pipe inner, Joystick is positioned at the top of valve pipe and valve body, Joystick and valve body link together, and rotate Joystick, valve body downward or upward movement is controlled flow.This valve in use finds, because using for a long time, valve rod is combined face with the connection of ball valve easy to wear, causes valve rod and valve to be in the slippage state and can't use.
The model utility content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of manual control ball valve, and it can make valve rod and valve combination securely, increases the service life.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of manual control ball valve, comprise valve body (4), valve (8), valve rod (3), described valve (8) is installed in described valve body (4) inner chamber, described valve rod (3) links to each other with valve (8), described valve body (4) comprises that one enters water cavity (10) and a water chamber (9), the end that described valve rod (3) stretches out described valve (8) is connected with handle (2) and fixing with gland nut (1), the end that described valve rod (3) links to each other with valve (8) is provided with dovetail groove (7), and described valve (8) is provided with the groove (5) that matches with described dovetail groove (7).
As preferably, the described exterior edge face that enters water cavity (10) and water chamber (9) is respectively equipped with flange land (6).
(3) beneficial effect
The utility model is compared to prior art, it has following beneficial effect: because an end that links to each other with valve at valve rod is provided with dovetail groove, valve is provided with the groove that matches with dovetail groove, has therefore increased lifting surface area, make valve rod more solid and reliable with being connected of valve, increase working life; The utility model is simple in structure, and modern design has practicability.
Description of drawings
Fig. 1 is the structural representation of manual control ball valve of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of manual control ball valve as shown in Figure 1, comprise valve body 4, valve 8, valve rod 3, valve 8 is installed in valve body 4 inner chambers, valve rod 3 links to each other with valve 8, valve body 4 comprises that one enters water cavity 10 and a water chamber 9, the end that valve rod 3 stretches out valve 8 is connected with handle 2 and fixing with gland nut 1, and handle firmly is connected on the valve rod, and the easily rotation of control valve comes the water flow of control valve body.The end that valve rod 3 links to each other with valve 8 is provided with dovetail groove 7, and valve 8 is provided with the groove 5 that matches with dovetail groove 7, has therefore increased lifting surface area, makes valve rod more solid and reliable with being connected of valve, increases working life.The exterior edge face that enters water cavity 10 and water chamber 9 is respectively equipped with flange land 6, and the flange land can be connected with water pipe, and safe and reliable.
The utility model is simple in structure, and modern design has practicability.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
