[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment

[0023] Please refer to Figures 1 to 4 , which is an embodiment of the present invention. This embodiment provides a technical solution: a one-way valve assembly applied to a water jet loom, including

[0024] Valve body 1, inner valve seat 4 threadedly fixed inside valve body 1, tapered hole 41 opened at the center of inner valve seat 4, core seat 51 movably installed inside valve body 1, tapered valve core 52 welded and fixed at the bottom of core seat 51 and inserted into tapered hole 41, multiple circular through holes 53 opened on the surface of core seat 51, water spray ports and water inlet ports respectively arranged at the upper and lower ends of valve body 1. When the water pressure at the water inlet port of valve body 1 is greater than the water pressure at the water spray port, core seat 51 and tapered valve core 52 move upward, so that water flows through the gap between tapered hole 41 and tapered valve core 52 and flows to the water spray port of valve body 1 through circular through holes 53 to achieve water spraying. When the water pressure at the water spray port of valve body 1 is greater than the water pressure at the water inlet port, core seat 51 and tapered valve core 52 move downward, so that tapered valve core 52 blocks tapered hole 41 to complete the blockage. The above are all prior arts and will not be elaborated here;

[0025] And a filtering mechanism installed at the water inlet at the lower end of the valve body 1, including an end seat 21 installed on the lower surface of the valve body 1, a threaded joint 22 arranged at the bottom of the end seat 21 and integrally structured with the end seat 21, a plurality of strip-shaped through holes 23 penetrating through the surface of the threaded joint 22, and a clamping structure arranged between the end seat 21 and the valve body 1. In the later stage, an external water supply pipe can be threadedly connected to the threaded joint 22, so that the external water flow enters the inside of the valve body 1 through the strip-shaped through holes 23. Before the external water flow enters the water inlet of the valve body 1, it will be roughly filtered by the threaded joint 22, so that some foreign objects with larger volumes will be blocked by the threaded joint 22, while the water flow will normally pass through the strip-shaped through holes 23 and enter the inside of the valve body 1. At this time, the end seat 21 and the threaded joint 22 are equivalent to a filtering seat with holes, which can prevent some foreign objects with larger volumes from entering the inside of the valve body 1 and causing blockage.

[0026] Among them, the clamping structure includes two side clamping plates 31 movably installed on the two side surfaces of the end seat 21, triangular clamping blocks 33 welded and fixed on the inner sides of the tops of the side clamping plates 31, and an annular clamping groove 11 opened on the surface of the valve body 1. The triangular clamping blocks 33 are embedded in the annular clamping groove 11 to achieve the stable installation of the end seat 21 during daily use. The clamping structure also includes side grooves 34 opened inside the two sides of the end seat 21, inner sliding seats 35 movably installed inside the side grooves 34, side rods 37 welded and fixed on the sides of the inner sliding seats 35, and springs 36 arranged between the sides of the inner sliding seats 35 and the inner walls of the side grooves 34. The ends of the side rods 37 penetrate to the surface of the end seat 21 and are fixed to the side clamping plates 31. Under the pushing action of the springs 36, the triangular clamping blocks 33 can be stably clamped in the annular clamping groove 11 during daily use, ensuring the installation stability of the filtering mechanism. In the later stage, if the end seat 21 and the threaded joint 22 need to be removed for cleaning and maintenance, only the side clamping plates 31 need to be pulled sideways, so that the side rods 37 drive the inner sliding seats 35 to move sideways, and the springs 36 are compressed, causing the side clamping plates 31 to drive the triangular clamping blocks 33 to move sideways smoothly until the triangular clamping blocks 33 move out of the annular clamping groove 11, then the limit on the end seat 21 can be released. At this time, the end seat 21 is moved downward, so that the positioning block 24 is pulled out from the inside of the valve body 1, and the end seat 21 and the threaded joint 22 can be quickly removed from the water inlet of the valve body 1, which is convenient for later cleaning and maintenance.

[0027] Among them, one end of the spring 36 abuts against the side of the inner sliding seat 35, and the other end of the spring 36 abuts against the inner wall of the side groove 34.

[0028] Among them, side holes communicating with the side grooves 34 are opened on both side surfaces of the end seat 21, and the side holes are adapted to the side rods 37 to allow the side rods 37 to penetrate smoothly.

[0029] Among them, a bottom pulling seat 32 is welded and fixed on the bottom surface of the side clamping plate 31, and the bottom pulling seat 32 is in a C shape, which is convenient for subsequent operators to pull the side clamping plate 31 sideways through the bottom pulling seat 32.

[0030] Among them, two positioning blocks 24 are symmetrically welded and fixed on the top surface of the end seat 21, and the positioning blocks 24 are inserted into the inner side of the valve body 1 and fit with the inner wall of the valve body 1, which can play a positioning role for the end seat 21 when the end seat 21 is installed. When the positioning blocks 24 are inserted into the inner side of the valve body 1, the end seat 21 will not move horizontally left and right, improving the installation convenience.

[0031] Among them, an annular groove 42 is formed at the top end of the conical hole 41, and a sealing ring 43 is adhesively installed on the inner wall of the annular groove 42. The sealing ring 43 is made of rubber material, and the sealing ring 43 is in close fit with the conical valve core 52 to ensure the sealing performance after the conical valve core 52 is inserted into the inner side of the conical hole 41.

[0032] Although the embodiments of the present invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
