[0016] 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.

[0017] See also Figure 1-3 The utility model provides a technical solution: a stretching end valve housing that is easy to disassemble, including a main valve housing 2, one side of the main valve housing 2 is provided with an external thread, one side of the main valve housing 2 is provided with a side valve housing 1, one side of the side valve housing 1 is provided with an internal thread, and the external thread and the internal thread are threadedly connected to each other. When in use, since the main valve housing 2 and the side valve housing 1 can be threadedly disassembled, when disassembling, the side valve housing 1 can be conveniently disassembled while the main valve housing 2 is connected to the pipeline, thereby improving the disassembly speed and facilitating maintenance;

[0018] A threaded valve stem 3 is provided inside the side valve housing 1, and a valve plate 4 is fixed to one end of the threaded valve stem 3 by welding. The side wall of the valve plate 4 and the inner wall of the main valve housing 2 are in sealing contact with each other. A threaded sleeve 6 is provided inside the side valve housing 1, and the inner wall of the threaded sleeve 6 and the threaded valve stem 3 are threadedly connected with each other. When the valve plate 4 needs to be disassembled quickly, the threaded sleeve 6 needs to be taken out instead of slowly twisting the threaded valve stem 3 to take it out, which is convenient for quick disassembly. During normal use, the threaded valve stem 3 is rotated to allow the valve plate 4 to be slowly fed for opening and closing.

[0019] An annular angle block 61 is fixed to one side of the threaded sleeve 6 by welding, and a limiting protrusion 62 is correspondingly arranged on the outer wall of the annular angle block 61, and a limiting groove is correspondingly arranged on the outer wall of one side of the side valve housing 1, and the limiting groove and the limiting protrusion 62 are engaged with each other. The position of the threaded sleeve 6 is limited by the annular angle block 61 when in use, and the annular angle block 61 and the threaded sleeve 6 can be removed when not in use;

[0020] The valve plate 4 is provided with filter devices 41 embedded in a circumferential distribution inside, and the upper and lower side walls of the side valve housing 1 are provided with through holes correspondingly, and the through holes are movably connected with connecting nozzles 5 through threads, and the internal liquid is filtered by the filter device 41. When cleaning is required, the external water source is connected to the two connecting nozzles 5 to form a complete circuit. At this time, water is pumped in one direction, preferably from bottom to top, and the filter device 41 can be reversely flushed to remove impurities intercepted on one side, which is convenient for maintenance and reduces the number of maintenance times;

[0021] A square head 42 is fixed to one side of the valve plate 4 by welding, and a liquid penetration groove 421 is provided on one side of the square head 42. The square head 42 is used for waterproof sealing. Due to the existence of the liquid penetration groove 421, the cleaning liquid can penetrate into the liquid penetration groove 421, and water leakage will not occur during normal use.

[0022] The annular angle block 61 is made of spring steel. The design of the spring steel material can ensure that when the annular angle block 61 is pulled outward, it can be slightly deformed, so that the limiting groove and the limiting protrusion 62 are separated from each other.

[0023] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
