[0037] Embodiment one

[0038] The embodiment provides a quick-mounting valve, in the embodiment, the quick-mounting valve is a gate valve, in other embodiments, the quick-mounting valve can also be a ball valve, a stop valve, a check valve or a pressure reducing valve, which is not limited here.

[0039] Specifically, as shown in Figure 2 And Figure 3 The quick-mounting valve comprises a valve body 1, the valve body 1 comprises a first joint and a second joint, wherein the first joint is a socket structure 2, the second joint is a spigot structure 3, a limiting groove 31 is arranged on the outer wall of the spigot structure 3, in order to facilitate the quick-mounting valve to adjust the direction in the assembly process, the limiting groove 31 surrounds the outer wall of the spigot structure 3, the socket structure 2 comprises a body 21 and a connecting boss 22, the body 21 is provided with a plug hole 211, the plug hole 211 penetrates the side wall of the body 21 and divides the body 21 into a first section and a second section, and the connecting boss 22 is protruded on the outer side wall of the body 21 and arranged between the first section and the second section.

[0040] The quick-mount valve provided by the embodiment can be processed by using a lathe processing device when processing the inner hole of the socket structure 2 and the insertion hole 211, thereby greatly improving the processing efficiency and reducing the production cost.

[0041] By arranging the connecting boss 22 on the side wall of the body 21, the wall thickness of the body 21 at the position of the connecting boss 22 is increased. When the insertion hole 211 is processed, the socket structure 2 will not be broken due to the connecting action of the connecting boss 22, and the structural strength of the socket structure 2 can still be ensured.

[0042] By Figure 2 It can be seen that the cross section of the socket structure 2 is circular, and thus the insertion hole 211 is an annular hole and penetrates the side wall of the body 21 in the radial direction.

[0043] In the embodiment, as shown in Figure 4 , the inner diameter r of the connecting boss 22 can be slightly larger than the outer diameter R of the body 21, that is, after the insertion hole 211 penetrates the body 21, a certain depth of the connecting boss 22 is further processed, but the depth is very small and needs to ensure the structural strength. In other alternative embodiments, the inner diameter r of the connecting boss 22 can be equal to the outer diameter R of the body 21, that is, the insertion hole 211 just penetrates the body 21 and does not process the connecting boss 22.

[0044] Referring to Figure 5 and Figure 6 , the embodiment takes the connection of the gate valve with the first valve and the second valve as an example. The first valve and the second valve can be commonly used valves in water affairs, such as ball valves, gate valves, stop valves, check valves, pressure reducing valves, etc. Of course, the quick-mount valve can also be connected with other pipelines.

[0045] As can be seen from the drawings, the first valve has a first insertion port structure 100, which is completely the same as the insertion port structure 3 of the quick-mount valve in the embodiment. The first insertion port structure 100 is provided with a first limiting groove 1001, and the outer diameter of the first insertion port structure 100 is less than or equal to the inner diameter of the socket structure 2. After assembly, the first insertion port structure 100 of the first valve is inserted into the socket structure 2, and is axially limited by the U-shaped insertion plate 300. Figure 6 As can be seen from the drawings, after the free end of the U-shaped insertion plate 300 extends into the insertion hole 211, part of the U-shaped insertion plate 300 also falls into the first limiting groove 1001 of the first insertion port structure 100. The two elastic arms of the U-shaped insertion plate 300 tightly hold the first insertion port structure 100, thereby achieving the axial limiting action between the first insertion port structure 100 and the socket structure 2, and achieving the axial fixed connection between the first joint and the first valve. When disassembling, the U-shaped insertion plate 300 can be pulled out outward, which is convenient and fast, and greatly improves the disassembly efficiency.

[0046] Similarly, the second valve has a second socket structure 200, which is completely the same as the socket structure 2 of the quick-mount valve in the embodiment, and the inner diameter of the second socket structure 200 is greater than or equal to the outer diameter of the spigot structure 3. After assembly, the spigot structure 3 is inserted into the second socket structure 200 of the second valve, and is axially limited by the U-shaped plug plate 300, so as to realize the axial fixed connection between the second joint and the second valve. The connection mode is the same as the connection mode of the first spigot structure 100 and the socket structure 2 through the U-shaped plug plate 300, and will not be described here.

[0047] In combination with Figure 2 and Figure 6 In the embodiment, two oppositely arranged connecting bosses 22 are protruded on the outer side wall of the body 21. The two connecting bosses 22 can be distributed up and down, and the U-shaped plug plate 300 is inserted in the horizontal direction; or the two connecting bosses 22 can also be distributed left and right, and the U-shaped plug plate 300 is inserted in the direction from bottom to top; of course, the two connecting bosses 22 can also be oppositely distributed in other directions, which is not specifically limited here.

[0048] In the embodiment, the U-shaped plug plate 300 is used to complete the axial limiting. After the U-shaped plug plate 300 is inserted into the insertion hole 211, the two connecting bosses 22 are respectively located on the outer sides of the two elastic arms of the U-shaped plug plate 300, so as to limit the U-shaped plug plate 300 and prevent the U-shaped plug plate 300 from rotating, so that the U-shaped plug plate 300 is not easy to fall out and connection failure is avoided. By arranging the U-shaped plug plate 300, the U-shaped plug plate 300 is subjected to bilateral force in the axial direction, the force is uniform, the coaxialities of the first spigot structure 100 and the socket structure 2 and the second socket structure 200 and the spigot structure 3 are ensured, the non-uniform axial force caused by the water pressure of the pipeline is avoided, and the sealing leakage of the two is avoided, and the limiting force of the U-shaped plug plate 300 is a plane contact force, which can increase the force area and avoid damage and deformation caused by long-term axial force.

[0049] However, the utility model is not limited to this form, and other structural forms can also be used, such as a U-shaped plug (with a circular cross section), but the limiting force of the U-shaped plug is a line contact force, which is different from the U-shaped plug plate 300. In another optional embodiment, the two single plug plates or the two single plugs can also be arranged in a symmetrical manner.

[0050] For example Figure 7As shown, in another alternative embodiment, three connecting bosses 22 can also be protruded on the outer side wall of the body 21 to further enhance the structural strength of the socket structure 2. Among them, the first two connecting bosses 22 can be relatively distributed in the circumferential direction of the insertion hole 211, and the third connecting boss 22 is arranged at the intermediate position of the above two connecting bosses 22 in the circumferential direction of the insertion hole 211, so that when the U-shaped plug plate 300 is inserted into the insertion hole 211, the first two connecting bosses 22 can be located on the outer side of the two elastic arms of the U-shaped plug plate 300 respectively for limiting, and the third connecting boss 22 can just avoid the two elastic arms of the U-shaped plug plate 300 when the U-shaped plug plate 300 is inserted.

[0051] In other embodiments, if the circumferential size of the connecting boss 22 is reduced, the number of connecting bosses 22 can also be adaptively increased, such as four, five or more, which is not limited here.

[0052] As shown in the drawings, Figure 3 The outer side wall of the socket structure 3 is provided with a first sealing groove (not marked in the figure due to the angle of view) which surrounds the circumferential direction thereof, and the first sealing groove is located between the end face of the socket structure 3 and the limiting groove 31. The first sealing groove is provided with a first sealing ring 4. The first sealing ring 4 is closer to the end face of the socket joint 3, and is mainly used for sealing between the socket structure 3 and the side wall of the second socket structure 200, to prevent liquid leakage.

[0053] Further, as shown in the drawings, Figure 3 The outer side wall of the socket structure 3 is provided with a second sealing groove (not marked in the figure due to the angle of view) which surrounds the circumferential direction thereof, and the second sealing groove and the first sealing groove are arranged on the two sides of the limiting groove 31. The second sealing groove is provided with a second sealing ring 5. The second sealing ring 5 has a smaller diameter than the first sealing ring 4, and mainly plays a role of sealing dust.
