The cylinder 71 of the second sleeve 7 is a cylinder structure with hollow inside and open upper and lower, the top edge of the cylinder 71 extends inwards to form a first limiting ring 72 with a certain width, the inner diameter of the lower part of the cylinder 71 is larger than the outer diameter of the track ring 3, and a second limiting ring 73 is formed on the inner wall of the lower part of the cylinder 71.

The first sleeve 1, the track ring 3, the second sleeve 7 and the spring 4 are assembled together to form a valve core integral assembly, and the valve core integral assembly can be taken out for replacement when the valve core is replaced. The specific assembly relation of the four parts is as follows: the cylinder 11 of the first sleeve 1 penetrates out of the through hole of the track ring 3, and the flange 12 of the first sleeve 1 is limited by the top of the second cylinder 32 of the track ring 3 to prevent the flange from falling off. The spring 4 is placed in the second sleeve 7, the top of the spring 4 is abutted against the bottom of the first limiting ring 72, and the bottom of the spring 4 is abutted against the top of the flanging 12. The rail ring 3 is inserted into the second sleeve 7 from the bottom open end, the top edge of the first cylinder 31 of the rail ring 3 is just limited by the second limiting ring 73 on the inner wall of the second sleeve 7, and the side wall of the first cylinder 31 and the inner wall of the second sleeve 7 are welded or riveted together.

In addition, for the valve core, the first cylinder 31 of the track ring 3 is matched with the second limiting ring 73 on the inner wall of the second sleeve 7, so that the problem of water leakage caused by the existence of a gap between the second sleeve 7 and the track ring 3 can be prevented.

After the valve core is assembled into a whole according to the above, the valve core is inserted into the valve housing 5 from the water inlet at the bottom of the valve housing to fix the valve core and prevent the valve core from falling off, an annular clamping groove (not labeled in the drawing) is formed in the inner wall of the valve housing 5 below the track ring 3, a clamp spring 2 with a notch is embedded in the annular clamping groove, and the bottoms of the track ring 3 and the second sleeve 7 are supported and limited by the clamp spring 2. Most of the existing valves are designed without considering the requirement of singly replacing the valve core, so that the clamp spring 2 cannot be taken out. In order to replace the valve core in this embodiment, a groove 9 (as shown in fig. 1 and 3) is formed in the inner wall of the valve housing 5 at one side of the water inlet, the groove 9 is communicated with an annular clamping groove embedded with the clamping spring 2, and a special tool can extend into the valve housing 5 to clamp the clamping spring 2 and take out the clamping spring by means of the groove 9, so that the valve core is replaced integrally.

Besides the improvement of the structure, the utility model also considers that the actual water supply pressure of domestic water is smaller, and in order to achieve the purposes of saving water and controlling the flow of the domestic water with higher precision, the design parameters of the valve are further optimized, namely: the pressure difference range of the angle valve in the prior art is adjusted from 10 to 300Kpa to 3 to 100Kpa, and the flow of the angle valve in the prior art is adjusted from 3.3 to 20L/min to 0.5 to 5.5L/min. The adjustment of pressure differential scope is realized mainly through the improved design of spring 4 parameter, and the spring wire diameter that uses among the prior art is thicker (usually 1 mm), the texture is harder, and its elasticity coefficient is great (usually 1.9N/mm), and the spring takes place deformation just to need very big thrust, and is more suitable for industrial water to use, and is difficult to promote it to the pressure of domestic water usually less for its regulation effect to the flow is very limited. Therefore, in this embodiment, the wire diameter of the spring 4 is made smaller to be 0.7mm to 0.8mm, preferably 0.8mm, and the spring modulus is selected to be 0.5N/mm to 1.0N/mm, preferably 0.93N/mm, so that the spring can be more suitably used for the pressure of domestic water.

The adjusting process of the angle valve with the structure to the dynamic balance of the domestic water is described as follows: in the pressure difference range of 3 Kpa-100 Kpa, when water flow enters from the water inlet of the valve casing 5, the pressure difference between the water inlet end of the first sleeve 1 and the water outlet end of the second sleeve 7 is increased, the water flow pushes the first sleeve 1 to move upwards to continuously compress the spring 4, and in the moving process, the water permeable hole area exposed on the first sleeve 1 is continuously reduced, according to the formula(G-flow, ζ -flow coefficient, A-water flow area, Δp-pressure difference), it is known that the flow G (0.5 Lmin. Ltoreq. G. Ltoreq. 5.5L/min) value remains unchanged; when the pressure difference between the water inlet end of the first sleeve 1 and the water outlet end of the second sleeve 7 is reduced, the elastic force of the spring 4 is continuously released and pushes the first sleeve 1 to start to move downwards, thereby causing the water permeable hole surface exposed on the first sleeve 1The product is increased continuously, but according to the flow formula, the flow G is still unchanged, so that dynamic balance adjustment of water flow is realized.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
