BRIEF DESCRIPTION OF DRAWINGS

[0014] Figure 1 It is integral device schematic diagram of the utility model.

[0015] Mark explanation:

[0016] 1 is magnetic control lock, 2 is valve stem, 3 is lock groove, 4 is valve body, 5 is external thread, 6 is sealing ring one, 7 is telescopic valve cap, 8 is compression nut, 9 is telescopic connector, 10 is loose joint nut, 11 is ball valve, 12 is sealing pad, 13 is sealing ring two, 14 is check valve, 15 is stainless steel clamp. DETAILED DESCRIPTION

[0017] The utility model will be further described in combination with the drawings.

[0018] Reference Figure 1 The utility model provides a new type magnetic lock check telescopic ball valve, the inside of valve body 4 is provided with ball valve 11, ball valve 11 is connected with magnetic control lock 1 through valve stem 2, and the valve body outside valve stem 2 is provided with lock groove 3, and the water inlet end of valve body 4 is connected with external thread 5, and the inside between valve body 4 and ball valve 11 is provided with sealing pad 12, and the water outlet end of valve body 4 is connected with telescopic valve cap 7, and telescopic valve cap 7 is connected with telescopic connector 9, and the inside of telescopic connector 9 is provided with check valve 14, and the outside of telescopic connector 9 is provided with compression nut 8, and the between compression nut 8 and telescopic valve cap 7 is provided with sealing ring two 13, and the between telescopic valve cap 7 and check valve 14 is also provided with sealing ring two 13, and the water outlet end of telescopic connector 9 is connected with loose joint nut 10, and the water outlet end of telescopic connector 9 is provided with stainless steel clamp 15 matched with loose joint nut 10.
