[0042] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "arranged", "mounted", "connected", and "linked" should be understood broadly, for example, can be fixedly connected, or can be detachably connected, or integrally connected; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium, or can be connected internally between two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. Figure 2In the overall structure of the handle ball valve 10 shown, the valve body shell 110 is arranged in a horizontal direction, the first mounting portion 221 of the handle fixing member 220 is arranged in a vertical direction perpendicular to the valve body shell 110, the second mounting portion 222 of the handle fixing member 220 is arranged in a horizontal direction perpendicular to the handle fixing member 220, and the second mounting portion 222 and the valve body shell 110 are located in two mutually parallel horizontal planes; when the axis of the second mounting portion 222 is translated to the same horizontal plane as the axis of the valve body shell 110, the axes of the two intersect, which is conducive to the natural downward hanging of the gripping member 210 when not in operation, thereby saving space for the handle ball valve 10.

[0043] Specifically, the dynamic cooperation relationship between the gripping member 210 and the handle fixing member 220 and the corresponding structure are as follows:

[0044] Please refer to Figure 5 and Figure 6 , the second mounting portion 222 is provided with a mounting groove 2221 extending in the axial direction of the second mounting portion 222. In this embodiment, the mounting groove 2221 penetrates up and down at an angle shown in Figure 2 , thereby dividing the end of the second mounting portion 222 away from the first mounting portion 221 into two left and right parts.

[0045] The groove bottom of the mounting groove 2221 is an arc-shaped bottom 2222, that is, the surface of the mounting groove 2221 close to the first mounting portion 221 is arc-shaped, the arc-shaped bottom 2222 protrudes in the direction close to the first mounting portion 221, and the side of the groove bottom of the mounting groove 2221 away from the ball valve unit 100 is provided with a limiting groove 2224 to facilitate the structure of the gripping member 210; the two opposite groove walls of the mounting groove 2221 are also provided with through first mounting holes 2223.

[0046] Please refer to Figure 7 , the gripping member 210 includes a gripping portion 211 and a third mounting portion 212, the third mounting portion 212 protrudes from one end of the gripping portion 211 and is accommodated in the mounting groove 2221 in a clearance fit, the end face of the third mounting portion 212 away from the gripping portion 211 is an arc-shaped face 2121, and the arc-shaped face 2121 clearance fits with the arc-shaped bottom 2222; one end of the arc-shaped face 2121 is provided with a limiting protrusion 2122, and the limiting protrusion 2122 cooperates with the limiting groove 2224 for limiting; the third mounting portion 212 is provided with a second mounting hole 213 corresponding to the first mounting hole 2223, and the second connecting member 230 connects the gripping member 210 and the handle fixing member 220 through the first mounting hole 2223 and the second mounting hole 213.

[0047] The center of the first mounting hole 2223, the second mounting hole 213, the arc surface 2121 and the arc bottom 2222 is on the same axis, which is the axis of the second connecting piece 230. Therefore, the handle fixing piece 220 and the holding piece 210 can rotate relative to the axis on which the center of the above structure is located, so that the holding piece 210 can be lowered under the action of gravity in the non-use state, reducing the installation space of the handle ball valve 10.

[0048] The third mounting part 212 of the holding piece 210 is accommodated in the mounting groove 2221 of the second mounting part 222 of the handle fixing piece 220, and the holding piece 210 and the handle fixing piece 220 are positioned by the second connecting piece 230 passing through the two first mounting holes 2223 on the mounting groove 2221 and the second mounting hole 213 on the third mounting part 212. The arc bottom 2222 of the mounting groove 2221 and the arc surface 2121 of the third mounting part 212 are in shape fit, and the limiting protrusion 2122 at one end of the arc surface 2121 and the limiting groove 2224 at one end of the arc bottom 2222 are in shape fit. Therefore, the holding piece 210 can rotate relative to the handle fixing piece 220 with the second connecting piece 230 as the axis.

[0049] In the natural state, the holding piece 210 will naturally droop under the action of gravity, as shown in Figure 2 When it is necessary to operate the opening and closing of the valve ball 120, the holding piece 210 is lifted until the limiting protrusion 2122 is in contact with the limiting groove 2224, and then a horizontal force is applied to the holding piece 210 to rotate the handle unit 200 relative to the valve body shell 110. Since the handle fixing piece 220 of the handle unit 200 is connected to the valve stem 130 of the ball valve unit 100, when the handle unit 200 rotates relative to the valve body shell 110, the opening and closing of the valve ball 120 can be controlled through the valve stem 130 to realize the process of opening and closing the water.

[0050] The structure can naturally droop after installation, so that the external structure such as the water distribution tank cannot be closed due to the extension of the handle. In addition, the length of the holding piece 210 can be adjusted, for example, the length of the holding piece 210 can be increased to increase the force area of the holding piece 210 during operation, improve the torque, and reduce the difficulty of opening and closing the handle ball valve 10.

[0051] For example, in the present embodiment, the length of the holding piece 210 can be greater than 100 mm to increase the force area and reduce the operation difficulty.

[0059] Please refer to Figure 3 In the embodiment, the valve body shell 110 includes a valve body 113, a valve cover 114, a connecting pipe 115, a hot-melt pipe 116 and at least two lock nuts 117.

[0060] One end of the hole 140 of the valve body 113 is connected with the connecting pipe 115 through the lock nut 117, and the opposite end is threadedly connected with the valve cover 114, and the valve cover 114 is connected with the hot-melt pipe 116 through the lock nut 117.

[0061] The embodiment provides a handle foldable handle ball valve 10, and the installation process and working principle are as follows:

[0062] Please refer to Figure 1 and Figure 2 The valve ball 120 is located in the valve body 113, the valve stem 130 is accommodated in and extends out of the first opening end 111 of the valve body 113, one end of the hole 140 of the valve body 113 is connected with the connecting pipe 115 and is fixed through the lock nut 117 and a sealing member, the valve body 113 is threadedly connected with the lock nut 117, and the lock nut 117 and the connecting pipe 115 are clamped; the other end of the hole 140 of the valve body 113 is threadedly connected with the valve cover 114, the valve cover 114 is threadedly connected with the lock nut 117, the lock nut 117 is clamped with the hot-melt pipe 116, the hot-melt pipe 116 and the valve cover 114 are sealed, the valve cover 114 and the valve ball 120 are sealed, and a ball valve unit 100 is formed, so that the valve stem 130 is connected with a handle unit 200 and the valve body shell 110 is connected with external pipelines.

[0063] The third mounting portion 212 of the holding member 210 is arranged in the mounting groove 2221 of the handle fixing member 220, the second connecting member 230 passes through the first mounting hole 2223 and the second mounting hole 213, the holding member 210 is connected with the handle fixing member 220, and the holding member 210 rotates relative to the handle fixing member 220 with the second connecting member 230 as an axis.

[0064] The first mounting portion 221 of the handle fixing member 220 is sleeved on the surface of the valve stem 130 and the first opening end 111, the valve stem 130 passes through the U-shaped hole 2212 of the first mounting portion 221, the valve stem 130 is fixedly connected with the first mounting portion 221 through the first connecting member 300, and the protruding portion 112 on the valve body shell 110 is located in the limiting opening 2211 of the first mounting portion 221, that is, the installation of the handle ball valve 10 is completed.
