DETAILED DESCRIPTION

[0025] In order to further explain the technical scheme of the utility model, the utility model will be described in detail below through specific embodiments.

[0026] As Figures 1 to 5 shown, it is an improved water stop valve of the utility model, including shell 1 and movable rod 2, one end of movable rod 2 forms water outlet 21, water outlet 21 in movable rod 2 forms spanner hole 22 for connecting spanner, the cross-sectional area size of spanner hole 22 is 19-50mm 2 .

[0027] In this way, the improved water stop valve of the utility model, shell 1 is screw-mounted in water supply interface 100, when angle valve or faucet is installed in water supply interface 100, movable rod 2 moves inwards, realizes water passing.In the case that angle valve faucet is removed from water supply interface 100, movable rod 2 moves outwards, realizes water sealing.The cross-sectional area of spanner hole 22 is 19-50mm 2 . This ensures that spanner hole 22 has sufficient water flow, and ensures that the water flow through the angle valve and faucet is smooth, and the thickness of movable rod 2 is not too thin, and the structural strength is ensured.Further, the cross-sectional area of spanner hole 22 is 30-40mm

[0028] Spanner hole 22 is used for connecting hexagonal spanner or connecting square four-sided spanner with square cross section, spanner is inserted into spanner hole 22, and spanner is inserted into spanner hole 22 during use to drive movable rod 2 and shell 1 to rotate, so that the external thread 10 on the shell 1 is firmly installed with the internal thread in the water supply interface 100.

[0029] Preferably, shell 1 is formed with sliding cavity 12 along the axial direction, movable rod 2 is arranged in sliding cavity 12 along the axial direction, sliding cavity 12 is formed with limiting section 13 with square cavity section, and movable rod 2 has sliding section 25 with square cross section.Square sliding section 25 and square limiting section 13 cooperate with each other, the torque of spanner acting on movable rod 2 is transmitted to shell 1, and at the same time, it is ensured that movable rod 2 can slide along the axial direction relative to shell 1.

[0030] Preferably, the other end of movable rod 2 is fixedly connected with water stop pad 23, one end of sliding cavity 12 close to water stop pad 23 is formed with water inlet 11 that can be blocked by water stop pad 23, water passing cavity is formed in movable rod 2, water passing cavity and water inlet 11 are connected through the side of movable rod 2, and the water passing area of water inlet 11 and water passing cavity is greater than the cross-sectional area of spanner hole 22 when movable rod 2 is in the water outlet position.In this way, the water passing capacity is further ensured.

[0031] Preferably, the water passing holes 24 are formed on four sides of the sliding section 25. The water passing holes 24 are provided with four, so that the water flow can smoothly enter the center of the movable rod 2, guaranteeing the water passing capacity.

[0032] Preferably, a fixed convex edge 26 is formed on the movable rod 2 outside the water outlet 21; the fixed convex edge 26 is sleeved with a sealing gasket 3; the sealing gasket 3 is in a Chinese character shape in cross section, including an upper sealing surface, a side connecting surface and a lower sealing surface, a limiting cavity is formed on the inner side of the sealing gasket 3, and the fixed convex edge 26 is movably embedded into the limiting cavity. Since the sealing gasket 3 can rotate relative to the fixed convex edge 26, when the angle valve is screwed into the water supply connector and abuts against the sealing gasket 3, and then is screwed again, the sealing gasket 3 is not easy to be twisted in the circumferential direction, so that the yield is guaranteed, and the water leakage is reduced.

[0033] Preferably, the movable rod 2 is sleeved with a spring 4, one end of the spring 4 abuts against the shell 1, and the other end of the spring 4 abuts against the fixed convex edge 26; an annular limiting space is arranged between the inner side of the lower sealing surface and the movable rod 2, and the end portion of the spring 4 is contained in the annular limiting space.
