DETAILED DESCRIPTION

[0022] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0023] EMBODIMENT

[0024] The following will be described in conjunction with the drawings Figure 1 -Appendix Figure 6 The ball-shaped stop valve of the emulsion high-pressure filtering station for hydraulic support is described in further detail. The ball-shaped stop valve of the emulsion high-pressure filtering station for hydraulic support comprises a control assembly 1 and a valve body assembly 2. The control assembly 1 is rotatably installed in the valve body assembly 2. The valve body assembly 2 comprises a filter assembly 21, a fixed plate 22, a flange assembly 23, and a through hole 24. The flange assembly 23 is fixed on the ball-shaped stop valve shell through the fixed plate 22. The control assembly 1 comprises a stable assembly 11, an adjusting body 12, and a rotating disc 13. The stable assembly 11 is fixed on the side of the adjusting body 12 away from the rotating disc 13. The stable assembly 11 comprises a rotating wheel 111 and a stable shaft 112. The rotating wheel 111 is fixed on the side of the stable shaft 112 away from the stable shaft 112. The stable shaft 112 comprises a moving shaft body 1121, a limit ring 1122, and a high-strength spring 1123. The moving shaft body 1121 is fixedly installed with the limit ring 1122 on the side close to the high-strength spring 1123. The stable shaft 112 further comprises a solid shaft body at the lower end. The stable shaft 112 is provided with an even number of insertion slots 1124 in the solid shaft body. The limit ring 1122 is fixedly connected with an even number of inserts 1125 at the end away from the moving shaft body 1121. The filter assembly 21 comprises an outer ring 211. The outer ring 211 is fixedly connected with a filter screen 212 for filtering solid substances at the center position. The flange assembly 23 comprises a flange plate 231. The inner wall of the through hole in the center of the flange plate 231 is provided with an internal thread 232. The outer side of the outer ring 211 is provided with an external thread 213. The external thread 213 is fixedly connected with the internal thread 232. The insert 1125 is a rectangular block body with a circular arc on one side. The adjusting body 12 is a V-shaped notch ball body. The insertion slot 1124 is a rectangular block groove with a circular arc on one side.

[0025] Wherein, the moving shaft body 1121 is pressed by the high-strength spring 1123 to extend downward, and the length of the extension is just enough to insert the insert 1125 into the insertion slot 1124. When the ball-type stop valve of the emulsion high-pressure filter station for hydraulic support is not in use, the high-strength spring 1123 will directly move the moving shaft body 1121 upward. At this time, the user cannot rotate the adjusting body 12 by rotating the rotating wheel 111, thereby preventing the operator from misoperating the ball-type stop valve of the emulsion high-pressure filter station for hydraulic support.

[0026] Wherein, the diameter of the limiting ring 1122 is larger than the diameter of the uppermost end of the stable shaft 112, so the limiting ring 1122 cannot move away from the stable shaft 112. At this time, due to the high strength of the high-strength spring 1123, the extension force of the high-strength spring 1123 will directly press the adjusting body 12 and the rotating disc 13 downward, thereby preventing the adjusting body 12 from rotating when the water flow impacts it.

[0027] Wherein, the outer thread 213 and the inner thread 232 are adapted to each other, so that when the filter assembly 21 is installed, only the outer thread 213 and the inner thread 232 need to be screwed together to complete the installation of the filter assembly 21.

[0028] Wherein, the outermost side of the flange assembly 23 is fixedly installed with a ring of sealing rings, so that when the ball-type stop valve of the emulsion high-pressure filter station for hydraulic support is in use, liquid leakage will not occur.

[0029] Wherein, the ball-type stop valve is a two-position three-way valve, and the ball-type stop valve has a first liquid inlet hole in communication with the liquid inlet pipe of the emulsion high-pressure filter station for hydraulic support, a second liquid inlet hole connected with the backwashing filter of the emulsion high-pressure filter station for hydraulic support, and a blowdown hole for discharging liquid. The second liquid inlet hole is selectively in communication with the first liquid inlet hole and the blowdown hole.

[0030] The working principle of the utility model is described as follows: the mechanical structure of the ball type stop valve of the emulsion high-pressure filtering station for hydraulic support is not explicitly described, and is screwed, in order to more intuitively observe the professional technical features, the bolt connection is appropriately hidden, when the valve body inside liquid flow regulation or opening and closing is needed, the runner 111 is grabbed by hand and pressed downward, at this time, the runner 111 presses the moving shaft body 1121 to move downward, and the high-strength spring 1123 is compressed under stress, finally, the insert 1125 is inserted into the insertion slot 1124, then the runner 111 is rotated again, the stable shaft 112 can be used to rotate the adjusting body 12 and the rotating disc 13, so as to avoid the misoperation of the ball type stop valve of the emulsion high-pressure filtering station for hydraulic support, when the ball type stop valve of the emulsion high-pressure filtering station for hydraulic support is not used, the high-strength spring 1123 is pressed downward to press the adjusting body 12 and the rotating disc 13, and the V-shaped notch shape of the adjusting body 12 is matched, so that the impact water flow cannot rotate the adjusting body 12, so that the ball type stop valve of the emulsion high-pressure filtering station for hydraulic support can be more convenient to adjust the adjusting body 12 on the basis of not rotating the adjusting body 12, and the practicality of the ball type stop valve of the emulsion high-pressure filtering station for hydraulic support is greatly improved.

[0031] The technical features of the above-described embodiments can be combined arbitrarily, and in order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.
