[0042] As shown in Figure 1 , Figure 2 and Figure 7 The utility model embodiment provides a valve structure, comprising first casing 1, second casing connection, first casing 1 and second casing 2 define the installation cavity 3, first limiting portion is arranged in installation cavity 3, first casing 1 and second casing 2 are detachably connected, valve body 4, be arranged in installation cavity 3, valve body 4 is provided with second limiting portion, first limiting portion and second limiting portion cooperate to limit valve body 4 in installation cavity 3.

[0043] The valve structure provided by the embodiment of the utility model, the first shell 1 and the second shell 2 are detachably connected, the valve body 4 is arranged in the mounting cavity 3 defined by the first shell 1 and the second shell 2, and in application, the first shell 1 and the second shell 2 can be communicated with corresponding pipelines to make the valve body 4 realize the functions of preventing liquid material backflow in the pipeline and the like. Since the first shell 1 and the second shell 2 are detachably connected, the valve body 4 can be conveniently disassembled by disassembling the first shell 1 and the second shell 2, thereby improving the disassembling convenience of the valve body 4. Meanwhile, since the first shell 1 and the second shell 2 are detachably connected, the valve structure can be installed with valve bodies 4 of various models, thereby improving the versatility of the valve structure. In addition, the first limiting part is arranged in the mounting cavity 3, the second limiting part is arranged on the valve body 4, the first limiting part and the second limiting part are matched to limit the valve body 4 in the mounting cavity 3, the mounting stability of the valve body 4 in the valve structure is improved, and the normal work of the valve body 4 is ensured.

[0044] In some embodiments, referring to Figure 1 , the first shell 1 and the second shell 2 can relatively move; the valve body 4 comprises a valve port part 41; and the valve structure can further comprise an adjusting piece 5 arranged in the mounting cavity 3 and connected with the first shell 1, the adjusting piece 5 being used for moving with the first shell 1 relative to the second shell 2 to adjust the opening size of the valve port part 41.

[0045] In the above embodiment, the adjusting piece 5 can move with the first shell 1 to adjust the opening size of the valve port part 41 of the valve body 4, thereby realizing the size adjustment of the flow of the valve body 4 and further realizing the control of the valve structure on the flow size, so that the valve structure can better meet the use requirement.

[0046] The implementation mode of the detachable connection and the relative movement of the first shell 1 and the second shell 2 can be various, for example, the first shell 1 and the second shell 2 can be threadedly connected, buckled or inserted.

[0047] The implementation mode of the movement of the adjusting piece 5 to adjust the opening size of the valve body 4 can also be various, for example, the valve port part 41 comprises a valve port and a baffle connected with the inner wall of the valve port at one end, the baffle is used for shielding the valve port, and the adjusting piece 5 can abut against the baffle when moving to make the baffle do cantilever movement, thereby changing the opening size of the valve port.

[0048] In some embodiments, referring to Figure 1 , at least the valve port part 41 on the valve body 4 can be an elastic part; and the adjusting piece 5 is used for changing the distance between the adjusting piece 5 and the valve port part 41 when moving with the first shell 1 relative to the second shell 2 to change the deformation amount of the valve port part 41.

[0049] It is understandable that the valve port 41 is an elastic part, which can undergo elastic deformation when liquid flows through it, and the adjusting member 5 can abut against the deformed valve port 41.

[0050] During the movement of the regulating member 5 with the first housing 1, the distance between the regulating member 5 and the valve port 41 is constantly changing. If the distance between the regulating member 5 and the valve port 41 is small, the elastic deformation of the valve port 41 due to the abutment of the regulating member 5 is small, resulting in a smaller opening of the valve port 41. If the distance between the regulating member 5 and the valve port 41 is large, the elastic deformation of the valve port 41 due to the abutment of the regulating member 5 is large, resulting in a larger opening of the valve port 41, thereby adjusting the flow rate of the valve body 4.

[0051] The valve body 4 can be a silicone cross valve, the valve port 41 is a cross-shaped cut, and the valve body 4 can be a flat silicone cross valve or a cylindrical silicone cross valve.

[0052] In some embodiments, see Figure 1 and Figure 5 The valve body 4 can be a cylindrical structure, and the valve body 4 can also include an opening 42 opposite to the valve port 41; the adjusting member 5 extends into the valve body 4 through the opening 42 and is arranged opposite to the valve port 41.

[0053] Since the adjusting member 5 extends into the valve body 4 and is positioned opposite to the valve port 41, the distance between the adjusting member 5 and the valve port 41 is easier to adjust, thereby improving the control accuracy of the valve port 41 opening and thus improving the control accuracy of the flow rate of the valve structure.

[0054] In some embodiments, see Figure 1 The first housing 1 may include a flow channel 131, which is connected to the mounting cavity 3. The adjusting member 5 may include a hollow column 51 and a baffle 52. One end of the column 51 is connected to the first housing 1 and communicates with the flow channel 131. The other end of the column 51 is connected to the baffle 52. The baffle 52 is disposed opposite to the valve port 41. The baffle 52 is provided with a through hole, through which the flow channel 131 communicates with the valve port 41. The adjusting member 5 is used to change the distance between the baffle 52 and the valve port 41 as the first housing 1 moves relative to the second housing 2.

[0055] The column 51 of the adjusting member 5 is communicated with the flow channel 131, the baffle 52 is communicated with the valve port 41 through the through hole on the baffle 52, and the baffle 52 is arranged opposite to the valve port 41, so that the liquid material can pass through the column 51 and the baffle 52 in sequence to reach the valve port 41 of the valve body 4 after entering the flow channel 131. During the liquid material flow process, the distance between the baffle 52 and the valve port 41 can be changed at any time, so as to realize real-time adjustment of the opening size of the valve port 41 during the liquid material flow process, and then realize real-time control of the flow of the valve body 4, and the use is more convenient and reliable.

[0056] Specifically, if the valve body 4 is a cylindrical silica cross valve, the valve port 41 includes a concave surface and a convex surface facing away from each other, and the baffle 52 is arranged opposite to the convex surface.

[0057] In some embodiments, the adjusting member 5 can be at least one protrusion, which protrudes into the valve body 4 and is arranged in abutment with the valve port 41, so as to adjust the opening size of the valve port 41 according to the distance between the adjusting member 5 and the valve port 41.

[0058] In some embodiments, the first shell 1 and the second shell 2 can be threadedly connected. On the one hand, the first shell 1 and the second shell 2 are more convenient to disassemble and assemble, and at the same time, the sealing between the first shell 1 and the second shell 2 can be guaranteed; on the other hand, the first shell 1 can drive the adjusting member 5 to move to adjust the opening size of the valve port 41.

[0059] As described above, the first limiting portion and the second limiting portion cooperate to limit the valve body 4 in the mounting cavity 3, thereby improving the installation stability of the valve body 4 in the valve structure. The structural forms of the first limiting portion and the second limiting portion can be various, as long as they can cooperate to limit the valve body.

[0060] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the first limiting portion can include a first annular protrusion 11 and / or a second annular protrusion 21, the first annular protrusion 11 is arranged on the inner wall of the first shell 1, the second annular protrusion 21 is arranged on the inner wall of the second shell 2, and the first annular protrusion 11 and the second annular protrusion 21 are arranged opposite to each other; the second limiting portion includes a flange 43 extending outwardly based on one end of the valve body 4, the flange 43 is in abutment between the first shell 1 and the second annular protrusion 21, or the flange 43 is in abutment between the second shell 2 and the first annular protrusion 11, or the flange 43 is in abutment between the first annular protrusion 11 and the second annular protrusion 21.

[0061] The first annular protrusion 11 and the second annular protrusion 21 can be annular protruding wall structures or annular protruding ridge structures, as long as they can fix the flange 43. In addition, only the first annular protrusion 11 can be provided, so that the first annular protrusion 11 and the inner wall of the second shell 2 clampingly fix the flange 43, or only the second annular protrusion 21 can be provided, so that the first shell 1 and the inner wall of the second annular protrusion 21 clampingly fix the flange 43, or both the first annular protrusion 11 and the second annular protrusion 21 can be provided, so that they clampingly fix the flange 43. In specific applications, the fixing mode of the flange 43 can be selected according to actual needs.

[0062] In some embodiments, the flange 43 can include a connecting wall extending in the radial direction of the valve body 4 and a side wall extending in the axial direction of the valve body 4, or the flange 43 can only include the connecting wall extending in the radial direction of the valve body 4. In addition, the thickness of the connecting wall and the side wall in the corresponding direction can be the same or gradually increase or decrease, so as to improve the stability of the first shell 1, the second shell 2, the first annular protrusion 11 and the second annular protrusion 21 to the flange 43.

[0063] In some embodiments, referring to Figure 1 , Figure 2 , Figures 4 to 6 , the valve body 4 is integrally formed with the flange 43, and the valve body 4 is a flexible valve body. The flange 43 can include a root portion 431 close to the valve body 4 and an end portion 432 away from the valve body 4, and the thickness of the root portion 431 is less than the thickness of the end portion 432. The end portion 432 abuts between the first shell 1 and the second annular protrusion 21, or the end portion 432 abuts between the second shell 2 and the first annular protrusion 11, or the end portion 432 abuts between the first annular protrusion 11 and the second annular protrusion 21.

[0064] For the valve body 4, the quality of the valve port portion 41 is particularly important, especially for flexible valve bodies such as silica gel cross valves. After the valve body 4 is assembled, the flange 43 of the valve body 4 is easy to pull the valve body 4, which is easy to cause the valve port portion 41 to be opened and other abnormal conditions. In this case, the valve port portion 41 is difficult to recover by itself, thereby affecting the normal work of the valve body 4.

[0065] In the above embodiments, by assembling the end portion 432 of the flange 43 and reducing the thickness of the root portion 431 of the flange 43, the impact of the flange 43 on the valve body 4 when the flange 43 is stressed can be reduced. Specifically, the smaller the thickness of the root portion 431, the smaller the impact of the pulling and extrusion of the flange 43 on the valve port portion 41. It can be understood that the thickness of the root portion 431 cannot be too small, otherwise it is easy to cause problems such as insufficient strength and reverse pressure bearing capacity of the valve body 4. For a silica gel cross valve, when the thickness of the flange root portion is less than 0.5 mm, the cross cut portion is less affected by the assembly quality.

[0066] In some embodiments, referring to Figure 1 , Figure 2 and Figure 7 , the first shell 1 and the second shell 2 each include a shell body 12 and a joint 13, the joint 13 is provided with a flow channel 131 therein, the flow channel 131 is communicated with the mounting cavity 3; the shell body 12 of the first shell 1 and the shell body 12 of the second shell 2 define the mounting cavity 3. The joint 13 can be a pagoda joint or a straight-through pipe joint.

[0067] Specifically in application, the first shell 1 and the second shell 2 can be communicated with the pipeline through the joint 13. Among them, the pagoda joint is suitable for direct connection with the hose, and the straight-through pipe joint is suitable for direct connection with the standard pipeline joint, which is convenient to install and has low cost.

[0068] The utility model embodiment further provides a kind of batching equipment, it includes the valve structure of preceding description.

[0069] The batching equipment provided in the utility model embodiment includes valve structure, so the batching equipment has all beneficial effects of valve structure, which will not be repeated here.

[0070] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
