Description

Technical Field

[0001] The utility model relates to the technical field of angle valves, in particular to an angle valve body which is convenient for maintenance. Background Art

[0002] Angle valve is a common control valve for pipeline connection.

[0003] The angle valve has the problem of poor sealing when used for a long time. It is necessary to remove the rubber sheet on the angle valve, then use a screwdriver to remove the screws, and then tighten the hexagonal nut on the valve to make it sealed. However, the sealing of the angle valve used for tap water will be reduced after long-term use, which will cause the screws to rust on them and cannot be removed by a screwdriver, eventually causing the cross slot to be damaged and unable to be removed. In this case, the entire valve needs to be replaced, which is very inconvenient and increases maintenance costs. For this reason, the present application proposes an angle valve body that is easy to maintain. Utility Model Content

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides an angle valve body that is easy to maintain, including:

[0022] An angle valve body 1, a valve stem 4 is installed on the angle valve body 1, a knob 2 is installed on the valve stem 4, and rotating the knob 2 drives the valve stem 4 to rotate, so as to control the opening and closing of the angle valve body 1;

[0023] A connecting assembly for disassembling and assembling the valve stem 4 and the knob 2; the connecting assembly comprises a rectangular groove 5 arranged on the valve stem 4, a circular groove 12 is provided through the knob 2 from top to bottom, the circular groove 12 is sleeved on the outside of the valve stem 4 and is slidably connected, a rectangular frame 9 is fixed to the inner wall of the circular groove 12, and an opening portion of the rectangular frame 9 is arranged opposite to the rectangular groove 5;

[0024] Two connecting plates 11 extending into the rectangular groove 5 are fixed at the bottom of the rectangular frame 9. The connecting plates 11 are detachably connected to the valve stem 4. A hemispherical groove 6 is provided on the inner wall of the rectangular groove 5. A hemispherical block 7 is fixed on the connecting plate 11. The hemispherical block 7 is slidably connected in the hemispherical groove 6. The hemispherical block 7 is buckled in the hemispherical groove 6, and the connecting plate 11 can be connected to the valve stem 7 together. Therefore, rotating the knob 2 can drive the rectangular frame 9, the connecting plate 11 and the valve stem 4 to rotate, and can control the switch of the angle valve body 1; but the stability of tightly buckling the spherical block 7 in the hemispherical groove 6 is insufficient, and it is easy to fall off. For this reason, a rectangular rubber column 10 is provided in the rectangular groove 5, and a pull strip or a pull block can be provided on the rectangular rubber column 10 for easy removal; the rectangular rubber column 10 is set against the two connecting plates 11, and the connecting plate 11 is squeezed by the rectangular rubber column 10, so that the hemispherical block 7 is buckled in the hemispherical groove 6, so that the knob 2 can be stably connected to the valve stem 4;

[0025] In addition, in order to prevent the rectangular rubber column 10 from being separated from the connecting plate 11 and the rectangular groove 5, a protrusion 8 is fixedly connected to the connecting plate 11, and the protrusion 8 is arranged opposite to the hemispherical block 7, and the protrusion 8 is arranged against the rectangular rubber column 10. The protrusion 8 squeezes the rectangular rubber column 10 to deform it, thereby limiting the position of the rectangular rubber column 10 and preventing it from falling off;

[0026] A rubber plug 3 is installed at the upper end of the knob 2 to block the circular groove 12. The upper end of the rubber plug 3 is flush with the upper end of the knob 2, which is more beautiful. The product logo can be printed on the rubber plug 3.

[0027] When the angle valve body 1 needs to be tightened and sealed, the staff removes the rubber plug 3 with a screwdriver, and the rectangular rubber column 10 is exposed. The rectangular rubber column 10 is removed and the knob 2 is pulled up. Under pressure, the hemispherical block 7 disengages from the hemispherical groove 6, so that the knob 2 can be removed, and the hexagonal bolt at the bottom of the valve stem 4 can be tightened to achieve the sealing and tightening of the valve body 1. The operation is simple and convenient, avoiding the disadvantage of the prior art of using screws for tightening that causes rust and cannot be removed, and reducing the replacement cost.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
