The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-2, an embodiment of the present utility model is provided: a stop valve for PPR pipe comprises a valve body 1, a valve core 2 arranged on the valve body 1 and a supporting piece 3 arranged on the valve core 2; and the valve body 1 is fixed on the supporting surface by a supporting rod 33 arranged on the supporting piece 3. In summary, when the hand wheel on the valve core 2 rotates, the valve body 1 is fixed by the supporting member 3, so the valve body 1 cannot rotate along with the hand wheel, and the problem that water is easy to leak at the joint of the valve body 1 and the water pipe due to twisting and shaking between the pipeline at two ends of the valve body 1 and the valve body 1 caused by rotation of the hand wheel is avoided. Particularly, the valve body 1 is fixed by the support piece 3, so that the phenomenon that water leakage occurs at the joint of the stop valve and the water pipe when the stop valve is twisted after the rural household water meter is effectively solved.

Further, since the support 3 includes the connection plate 30 and the support rod 33 is movably mounted on the connection plate 30, the connection plate 30 and the support rod 33 are convenient to connect, and the support 3 is also convenient to be assembled to the valve core 2 by using the connection plate 30.
