The second fastener 400 is passed through the through hole and threadedly connected with the threaded hole to lock and fix the second valve block 300 and the first valve block 200; when the second fastener 400 is a bolt, a through hole can be set on both the second valve block 300 and the first valve block 200, and the second fastener 400 is threadedly connected with a nut after passing through the through holes on the second valve block 300 and the first valve block 200 to lock and fix the second valve block 300 and the first valve block 200. Specifically, refer to Figure 2In one embodiment, the second fastener 400 is a screw. Considering that the motor module 100 needs to be installed on the side of the first valve block 200 facing away from the second valve block 300, a through hole is provided on the second valve block 300 and a threaded hole is provided on the first valve block 200, so that the screw head of the second fastener 400 can be located on the side of the second valve block 300 facing away from the first valve block 200, thereby facilitating the subsequent independent disassembly and assembly of the second valve block 300.

[0036] It is understandable that, referring to Figure 1 and Figure 3 A first opening 211 is provided on the side of the first valve block 200 facing away from the second valve block 300. The first opening 211 is connected to the interior of the first valve block 200, so that the control element installed in the first valve block 200 can extend to the outside of the valve body through the first opening 211, or the output shaft 112 of the motor 110 in the motor module 100 can pass through the first opening 211 to extend into the first valve block 200, thereby facilitating the output shaft 112 of the motor 110 to connect to the driving opening and closing parts, or facilitating the adjustment of the moving stroke of opening and closing parts such as the valve stem 500; at the same time, in order to facilitate the connection of the motor module 100, a plurality of first clamping blocks 212 are also provided on the side of the first opening 211 of the first valve block 200, and the plurality of first clamping blocks 212 are distributed at intervals along the circumference of the first opening 211.

[0037] It is understandable that, referring to Figure 1 and Figure 2 The motor module 100 is arranged on the side of the first valve block 200 away from the second valve block 300, and includes a motor 110, a connecting block 120 and a first fastener 130. The first fastener 130 is passed through the connecting block 120 and is threadedly connected to the stator flange 111 of the motor 110, thereby fixing the motor 110 on the connecting block 120; at the same time, in order to facilitate the connection of the first valve block 200, the connecting block 120 is provided with a plurality of second clamping blocks 122 distributed at intervals around the output shaft 112 of the motor 110, and a slot 123 is formed between adjacent second clamping blocks 122 to allow the first clamping block 212 to pass through.

[0038] It should be understood that in order to achieve a fast rotation connection between the motor module 100 and the first valve block 200, refer to Figures 2 to 5In some embodiments, the first valve block 200 is formed with a first clamping groove 214 on one side of the first clamping block 212 close to the second valve block 300. The first clamping groove 214 is used to clamp with the second clamping block 122, and the width of the first clamping groove 214 matches the thickness of the second clamping block 122, so that the two sides of the second clamping block 122 in the thickness direction can respectively abut against the two opposite groove walls of the first clamping groove 214; therefore, when installing the motor module 100 on the first valve block 200, it is only necessary to align the slot 123 on the motor module 100 with the first clamping block 212, and then push the motor module 100 toward the first valve block 200. Valve block 200, and make the first clamping block 212 pass through the slot 123, the second clamping block 122 pass through the gap between the first clamping blocks 212, and then rotate the motor module 100, so that the second clamping block 122 can be clamped into the first clamping slot 214; and when it is necessary to disassemble the motor module 100, it is only necessary to rotate the motor module 100, so that the second clamping block 122 is disengaged from the first clamping slot 214, the second clamping block 122 is aligned with the gap between the first clamping blocks 212, the first clamping block 212 is aligned with the slot 123, and then the motor module 100 is pulled away from the first valve block 200.

[0039] It should be understood that, in order to achieve rapid rotational connection between the motor module 100 and the first valve block 200, in addition to the above-mentioned method of connecting and adapting with the second connecting block 122 by means of the first connecting groove 214, in some other embodiments, a second connecting groove (not shown in the drawings) can be formed on the motor module 100 on the side of the second connecting block 122 away from the second valve block 300, and the second connecting groove is used to connect with the first connecting block 212, and the width of the second connecting groove matches the thickness of the first connecting block 212, so that the two sides of the first connecting block 212 in the thickness direction can respectively abut against the two opposite groove walls of the second connecting groove; thus, when the motor module 100 is installed on the first valve block 200, it is only necessary to The slot 123 on the module 100 is aligned with the first clamping block 212, and then the motor module 100 is pushed toward the first valve block 200, and the first clamping block 212 passes through the slot 123, and the second clamping block 122 passes through the gap between the first clamping block 212, and then the motor module 100 is rotated to make the first clamping block 212 snap into the second clamping slot; and when the motor module 100 needs to be disassembled, it is only necessary to rotate the motor module 100 so that the first clamping block 212 is disengaged from the second clamping slot, the second clamping block 122 is aligned with the gap between the first clamping block 212, and the first clamping block 212 is aligned with the slot 123, and then the motor module 100 is pulled away from the first valve block 200.

[0040] Alternatively, in some other embodiments, a second clamping groove can be formed on the motor module 100, located on the side of the second clamping block 122 facing away from the second valve block 300, and a first clamping groove 214 can be formed on the first valve block 200, located on the side of the first clamping block 212 close to the second valve block 300, so that the first clamping groove 214 is clamped with the second clamping block 122, and the second clamping groove is clamped with the first clamping block 212, so as to jointly realize the clamping between the motor module 100 and the first valve block 200.

[0041] It should be understood that, according to some of the above embodiments, since the motor module 100 is clamped to the first valve block 200 by the cooperation of the second clamping block 122 and the first clamping groove 214, and / or, is clamped to the first valve block 200 by the cooperation of the second clamping groove and the first clamping block 212, when it is necessary to disassemble the motor 110, it is only necessary to rotate the motor module 100 and align the slots 123 between the second clamping blocks 122 with the first clamping block 212, and then pull the motor module 100 in a direction away from the first valve block 200, so that the motor module 100 can be separated from the first valve block 200, and finally unscrew the motor module 100. The motor 110 can be disassembled by using the first fastener 130; and when installing a new motor 110, it is only necessary to first fix the motor 110 to the connecting block 120 by the first fastener 130 to form a motor module 100, and then align the slot 123 on the motor module 100 with the first clamping block 212 on the first valve block 200, and then push the motor module 100 toward the first valve block 200, and then rotate the motor module 100; therefore, the motor mounting structure of the embodiment of the first aspect of the present invention can not only make the valve device more compact in the width direction, but also facilitate the disassembly, assembly and replacement of the motor 110.

[0042] It is understood that in some embodiments of the present invention, in order to further improve the stability of the connection between the motor module 100 and the first valve block 200, referring to Figure 2 and Figure 3 The first valve block 200 is provided with a protruding clamping portion 210 at one end thereof facing away from the second valve block 300. The first opening 211 is provided on the side of the clamping portion 210 facing away from the second valve block 300. The first clamping block 212 is provided on the outer peripheral side of the clamping portion 210. The first clamping groove 214 is formed between the first clamping block 212 and the end surface of the first valve block 200. Figure 2 、 Figure 4 and Figure 5, a plug-in cavity 121 cooperating with the clamping portion 210 is formed on the connecting block 120, and the second clamping block 122 is arranged on the inner side of the opening of the plug-in cavity 121, so that the motor module 100 and the first valve block 200 can be plugged in with the help of the clamping portion 210 and the plug-in cavity 121, so as to improve the stability of the connection between the motor module 100 and the first valve block 200; and when installing the motor module 100, the opening of the plug-in cavity 121 on the motor module 100 can be aligned with the clamping portion 210 first, and the first clamping block 212 can be aligned with the slot 123, and then the motor module 100 can be pushed toward the first valve block 200, and the clamping portion 210 can be inserted into the plug-in cavity 121, and then the motor module 100 can be rotated.

[0043] It is understandable that in order to prevent the motor module 100 from rotating relative to the first valve block 200 due to vibration or other external factors during operation, thereby causing the second clamping block 122 to disengage from the first clamping groove 214, or causing the first clamping block 212 to disengage from the second clamping groove, in some embodiments, reference is made to Figure 1 、 Figure 3 and Figure 5 ,, A first rotation limiting structure 213 is provided on the first valve block 200, and a second rotation limiting structure 124 is provided on the connecting block 120. The second rotation limiting structure 124 cooperates with the first rotation limiting structure 213 to limit the rotation of the motor module 100 relative to the first valve block 200.

[0044] It is understood that in some embodiments of the present invention, reference Figure 1 、 Figure 3 and Figure 5The first rotation limiting structure 213 is arranged on the outer peripheral surface of the clamping portion 210, and the second rotation limiting structure 124 is arranged on the inner side wall of the plug-in cavity 121, and one of the first rotation limiting structure 213 and the second rotation limiting structure 124 is a clamping groove, and the other is a clamping protrusion that cooperates with the clamping groove, so that the rotation of the motor module 100 relative to the first valve block 200 is limited by the cooperation between the clamping protrusion and the clamping groove. In one embodiment, specifically, the first rotation limiting structure 213 is a card slot, the cavity wall of the plug-in cavity 121 is provided with an elastic plunger, and the second rotation limiting structure 124 is a positioning bead of the elastic plunger protruding from the inner cavity wall of the plug-in cavity 121; the elastic plunger includes a shell, a plunger spring and a positioning bead, the plunger spring and the positioning bead are arranged in the shell, the two ends of the plunger spring respectively abut the positioning bead and the inner wall of the shell, and an opening is provided at one end of the shell so that the positioning bead can protrude from the shell under the elastic force of the plunger spring, and the shell is provided with an external thread; a threaded hole facing the card slot is provided on the cavity wall of the plug-in cavity 121, and the elastic plunger is threadedly connected to the cavity wall of the plug-in cavity 121 through the external thread on the shell, and the positioning bead protrudes from the inner cavity wall of the plug-in cavity 121 to form a card bulge; since the positioning bead is protruded from the shell by the elastic force of the plunger spring, when installing the electric When the motor module 100 is installed, after the clamping portion 210 is inserted into the plug-in cavity 121, the positioning column retracts into the shell under the pressure of the side surface of the clamping portion 210, and then the motor module 100 is rotated and when the second clamping block 122 enters the first clamping groove 214, or when the first clamping block 212 enters the second clamping groove, the positioning column will align with the clamping groove and enter the clamping groove under the elastic force of the plunger spring; and when the motor module 100 is removed, when the motor module 100 is manually rotated to make the second clamping block 122 disengage from the first clamping groove 214, or to make the first clamping block 212 disengage from the second clamping groove, the positioning column will be able to retract into the shell again under the push of the groove wall of the clamping groove, so that the motor module 100 can quickly release the rotation restriction with the first valve block 200; therefore, with the help of the elastic plunger, the convenience of installation and removal of the motor 110 can be further improved.

[0045] It should be understood that, in addition to the option of using mutually cooperating slots and protrusions for the first rotation limiting structure 213 and the second rotation limiting structure 124, in some other instances, the first rotation limiting structure 213 can also be optionally set as a tightening screw threadedly connected to the wall of the plug-in cavity 121, and the second rotation limiting structure 124 can be a locking screw hole set on the side surface of the clamping portion 210, and the tightening screw is threadedly connected to the locking screw hole.

[0046] It should be understood that, in order to achieve a fast rotational connection between the motor module 100 and the first valve block 200, in other embodiments, similarly, the clamping portion 210 and the insertion cavity 121 may be reversed. For example, the clamping portion 210 may be provided on the connecting block 120, the output shaft 112 of the motor 110 passes through the clamping portion 210, and the clamping portion 210 is provided on the side of the connecting block 120 facing the first valve block 200, and the second clamping block 122 is provided on the outer periphery of the clamping portion 210. At the same time, the insertion cavity 121 may be provided on the first valve block 200, the first opening 211 is connected to the insertion cavity 121, and the first clamping block 212 is provided inside the first opening 211.

[0047] It is understandable that in order to improve space utilization, in one embodiment, referring to Figure 1 and Figure 4 Specifically, the cross-sectional dimensions of the first valve block 200 and the second valve block 300 in a direction perpendicular to the axial direction of the motor 110 are set to be the same as or close to the cross-sectional dimensions of the motor 110; and, specifically, the stator flange 111 of the motor 110 is provided with connecting holes at four corner points of the end face facing the connecting block 120, and the first fasteners 130 are screws and are correspondingly provided with 4 screws.

[0048] Reference Figure 6 The coating valve of the second embodiment of the present invention is described below, which includes the motor mounting structure of the first embodiment mentioned above. By adopting the motor mounting structure of the first embodiment mentioned above, not only can the coating valve be made more compact in the width direction, but also the motor 110 can be easily disassembled and replaced.

[0049] It can be understood that the coating valve further includes a valve stem 500, a control chamber 220 is provided in the first valve block 200, the first opening 211 is connected to the control chamber 220, the valve stem 500 is axially slidably provided in the first valve block 200 and the second valve block 300, and one end of the valve stem 500 extends into the control chamber 220; the motor 110 is a linear motor, the output shaft 112 of the motor 110 is located in the axial direction of the valve stem 500, and the output shaft 112 of the motor 110 passes through the first opening 211 and then extends into the control chamber 220; the valve stem 500 00 extends from one end of the motor module 100 to the liquid outlet 600 of the coating valve, so that moving the valve stem 500 toward the motor module 100 can gradually open the liquid outlet 600, and moving the valve stem 500 toward the direction away from the motor module 100 can gradually close the liquid outlet 600. Therefore, by controlling the length of the output shaft 112 of the motor 110 penetrating into the control chamber 220, the movement stroke of the valve stem 500 toward the side close to the motor module 100 can be changed, thereby changing the opening of the coating valve during operation to adjust the liquid outlet speed.

[0050] It should be understood that when the motor mounting structure of the first embodiment is applied to other types of valve devices, the motor 110 can also be a rotating motor, and the output shaft 112 of the motor 110 can be used to drive the valve core assembly arranged in the first valve block 200 to rotate, and thereby realize the opening and closing of the valve and other controls.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
