[0019] The following will further elaborate on the present utility model in combination with the embodiments given in the drawings.

[0020] Referring to Figures 1 to 8 as shown, the following embodiments are provided in this embodiment:

[0021] The globe valve in this embodiment includes a union nut 10, a valve body 20, a driving device 30 for controlling the rotation of a moving piece, a first stationary piece 40, a moving piece 50, a second stationary piece 60, a joint 70, a snap ring 80, and a union nut 90. The second stationary piece 60, the moving piece 50, the first stationary piece 40, and the union nut 10 are assembled in the valve body 20 in sequence from top to bottom. The second stationary piece 60 and the first stationary piece 40 are stationary relative to the valve body 20, and the driving device 30 drives the moving piece 50 to rotate so that the moving piece 50 forms a sealing fit relationship with the second stationary piece 60 and the first stationary piece 40. The valve body 20 is provided with a water inlet 21 and a water outlet 22; two through holes 61 and two blind holes 62 are arranged on the outer circumferential circle of the second stationary piece 60 at equal angular intervals of four equal parts, and the through holes 61 are always communicated with the water outlet 22 of the valve body; two conduction channels 51 are arranged diagonally on the outer circumferential circle of the moving piece 50 at equal angular intervals of four equal parts; the first stationary piece 40 is coaxially provided with a through hole 41 to form a hollow circular ring shape, which is always communicated with the water inlet 21 of the valve body.

[0022] The following driving device 30 is provided in this embodiment. As Figure 1 shown, this is a dial of the driving device 30. A driving hole 1 is opened at the position of the valve body 20 relative to the side wall of the moving piece 50. After the dial passes through the driving hole 1, it is linked with the moving piece 50 to drive the moving piece 50 to rotate between the first stationary piece 40 and the second stationary piece 60. Further, a plug rod 24 is fixed on the dial. A slot is opened on the outer side wall of the moving piece 50, and the plug rod 24 is inserted into the slot. In this way, the connection between the dial and the moving piece 50 is realized by inserting the plug rod 24 into the slot, so that the effect of quick detachable connection of the dial can be effectively realized. In this embodiment, in order to reduce the entry of foreign matters, an arc-shaped guard plate 23 is fixed on the side of the dial relative to the plug rod. An annular groove 2 is opened on the outer side wall of the valve body 20, and the driving hole 1 is opened at the bottom of the annular groove 2. Thus, through the combined structure of the arc-shaped guard plate 23 and the annular groove 2, the entry of foreign matters can be effectively reduced.

[0023] The functions generated by the moving piece 50 in different cooperation states with the second stationary piece 60 and the first stationary piece 40 are described in detail below.

[0024] Globe valve closed:

[0025] As Figure 6 shown, the driving device 30 drives the moving piece 50 to rotate, so that the conduction channel 51 of the moving piece 50 coincides with the blind hole 62 of the second stationary piece 60, and the water outlet does not discharge water, and the globe valve is in a closed state.

[0026] Globe valve opened and the flow rate adjusted simultaneously:

[0027] As Figure 7 and 8As shown in the figure, the driving device 30 drives the moving piece 50 to rotate, so that the conduction channel 51 of the moving piece 50 is partially or completely conducted with the through hole 61 of the second fixed piece 60, and the flow rate of the stop valve can be adjusted according to different conduction angles.

[0028] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
