[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 A stainless steel valve with quick socket connection includes a valve body 10 and two sets of connection components 20. The two sets of connection components 20 are respectively installed at the ports of the output end 11 and the input end 12, and the connection components 20 can be used to connect and fix the pipeline to the output end 11 or the input end 12 of the valve body 10.

[0020] In this embodiment, the valve body 10 may have an output end 11, an input end 12, a hand wheel 13, a valve stem 14 and a valve flap. The output end 11 and the input end 12 are formed on the valve body 10 and are both in communication with the inner cavity of the valve body 10; one end of the valve stem 14 extends into the valve body and is connected and fixed to the valve flap, and the other end of the valve stem 14 passes through the outside of the valve body and is connected and fixed to the hand wheel 13, so that when the valve stem 14 is rotated by the hand wheel 13, the valve flap can be used to follow the movement to adjust the opening and closing of the valve. The above valve can be implemented by using existing technology, which will not be repeated here.

[0021] See also Figure 2 and Figure 3The connection assembly 20 may include a first end sleeve 21, a second end sleeve 22, a nut 23, a bolt 24, and a pipe sleeve 25. One side of the first end sleeve 21 and the second end sleeve 22 are hinged to each other, and the other side of the first end sleeve 21 and the second end sleeve 22 are connected and fixed by the nut 23 and the bolt 24, so that when the first end sleeve 21 and the second end sleeve 22 are opened, the pipe to be connected can be inserted between the two, and when the first end sleeve 21 and the second end sleeve 22 are fixed, the connection and fixation of the pipe and the valve body 10 can be completed. The nut 23 is embedded in the first end sleeve 21, one end of the bolt 24 passes through the second end sleeve 22 and is threadedly connected with the nut 23, and the other end of the bolt 24 is immersed in the second end sleeve 22, so that after the connection between the pipe and the valve body 10 is completed, the bolt 24 can be prevented from being exposed to the outside, and the connection between the pipe and the valve body 10 requires fewer bolts, which is convenient for the connection operation. The pipe sleeve (25) is inserted between the upper gland (211) of the first end sleeve 21 and the lower gland (221) of the second end sleeve 22, and the pipe sleeve 25 is covered on the end of the pipe, so that the pipe can adapt to the diameter clamped and fixed between the first end sleeve 21 and the second end sleeve 22 when connected. The pipe sleeve 25 can be made of elastic rubber material, and an opening is pre-opened in the middle of the pipe sleeve 25 so that the conveying medium can flow through.

[0022] In this embodiment, the first end sleeve 21 may include an upper gland 211, two positioning protrusions 212, a connecting shaft 213, a positioning boss 214, and an embedding groove 215. The two positioning protrusions 212 are formed on one side of the outer wall of the upper gland 211, and the connecting shaft 213 passes through the two positioning protrusions 212 and is rotatably connected thereto, so that the first end sleeve 21 can deflect with the connecting shaft 213 as the rotation center axis. The positioning boss 214 is formed on the other side of the outer wall of the upper gland 211, and the embedding groove 215 is formed on the side of the positioning boss 214 facing the second end sleeve 22, and the shape and size of the embedding groove 215 are respectively adapted to the shape and size of the nut 23, so that the nut 23 can be pre-embedded into the embedding groove 215 and placed and fixed.

[0023] In this embodiment, the second end sleeve 22 may include a lower gland 221, a connecting protrusion 222, a connecting boss 223 and a countersunk hole 224. The connecting protrusion 222 is formed on one side of the outer wall of the lower gland 221, and the connecting protrusion 222 passes through the gap between the two positioning protrusions 212 and is rotatably connected with the connecting shaft 213, so that the lower gland 221 can also deflect with the connecting shaft 213 as the rotation center axis. The connecting boss 223 is formed on the other side of the outer wall of the lower gland 221, and the facing sides of the connecting boss 223 and the positioning boss 214 can be in close contact when the second end sleeve 22 and the first end sleeve 21 are buckled to form a circular ring. The countersunk hole 224 is formed on the connecting boss 223 and passes through the connecting boss 223, and the bolt 24 can be detachably inserted into the countersunk hole 224, and the user can use a screwdriver to extend into the countersunk hole 224 to tighten the bolt 24 and the nut 23 to complete the connection and fixation.

[0024] In this embodiment, one end of the connecting shaft 213 toward the valve body 10 passes through the positioning protrusion 212 and is fixedly connected to the valve body 10, so that the connecting assembly 20 as a whole can be used as an integrated unit with the valve body 10, reducing the number of disassembled parts of the device, thereby facilitating transportation, carrying, and installation.

[0025] In this embodiment, the depth of the countersunk hole 224 can be made greater than the height of the bolt 24, and then after tightening the bolt 24, sealant can be injected into the countersunk hole 224, and the sealant can fill the remaining gap between the bolt 24 and the countersunk hole 224. After the countersunk hole 224 is filled, on the one hand, corrosive media can be prevented from entering the countersunk hole 224 to affect the bolt 24, and on the other hand, the bolt 24 can be prevented from loosening and falling off.

[0026] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
