Problems solved by technology
[0010] However, according to the first example, the drain bolt engaging the fluid drain hole must be fully loosened in order to drain the fluid from the ball valve body
[0011] Therefore, this method is inefficient since the drain bolt must be rotated several times to fully loosen it, requiring a tool to loosen the bolt
[0012] In addition, in the case of preventing freezing by using a heating wire, there are problems in that electric power must be consumed and the weight of the ball valve increases

[0076] According to the first embodiment of the invention, one hole 251 and two recesses 250 and 257 are predetermined in the locking device 300 .
[0077] However, the number of holes and recesses may be determined differently for a stronger connection between the button 203 and the discharge valve body 201 and for adjusting the flow in multiple levels.
[0078] According to the first embodiment of the present invention, the locker 300 is operated immediately by contact.
[0079] Figure 5 Shows details of the button 203 of the discharge valve 100 of the ball valve according to the first embodiment of the invention.
[0080] refer to Figure 5 , the recesses 250 and 257 are formed as concave surfaces.
[0081] When the first fluid discharge hole 120 is opened, the locker 255 disposed in the hole 251 is inserted into the uppermost recess 250 .
[0082] The curved surfaces 270 and 280 of the uppermost recess 250 are formed such that the curvature of its upper portion 270 is...

A sort of ball valve, which includes: the main body of ball valve, which restricts the first channel that the liquid passes through; a ball, which restricts the second channel that the liquid passes through, the ball can arrange at the first channel rotatablely, thereby the first channel responds to the circumvolving of the ball and is open or closed selectively; the handle, which is arranged to the main body of ball valve rotatablely and is constructed to rotate the ball; and discharging valve, which is arranged at the liquid discharging hole formed at the main body of the ball valve, therefore the discharging valve discharges the liquid reserving at the surrounding space of the ball. The discharging valve includes: the main body of the discharging valve, which is arranged in the liquid discharging hole and restrain the first liquid discharging channel that connects to the liquid discharging hole; and the button, which is arranged in the first liquid discharging channel, thereby open or close the first liquid discharging channel selectively.
Description
technical field [0001] In general, the present invention relates to a ball valve, and more particularly, to a ball valve capable of preventing the fluid in the ball valve from freezing by effectively draining the fluid in the ball valve. Background technique [0002] Typically, ball valves are installed in the passage of a pipe or vessel and control the flow and pressure of fluids. [0003] A ball valve is a device that selectively opens and closes the passage of a fluid such as boiling water. [0004] refer to figure 1 , a traditional ball valve includes a ball valve body 5 , a ball 7 , and a handle 3 . [0005] Channels are formed in the ball 7 and the ball valve body 5 so that fluid can flow along figure 1 Flow through the channel in the direction of the arrow shown. [0006] The handle 3 is rotatably mounted to the ball valve body 5 , and one end of the handle 3 is fixedly connected to the ball 7 . Thus, by rotating the handle 3, the ball 7 can be rotated so that th...
