Detailed Description

The check valve of the grinder of the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 3, the check valve of the grinder in this embodiment is characterized by comprising a flange 1, an aluminum pipe 4, a rubber sleeve 2 and a screw fixing plate 5; an aluminum pipe 4 is welded on the flange 1; a water inlet 101 and a bolt through hole 102 are formed in the flange 1; a plurality of water outlets 3 and grooves 9 are arranged outside the aluminum pipe 4; a rubber sleeve 2 is arranged outside the aluminum pipe 4; a plurality of screw through holes 6 are formed in the rubber sleeve 2; a screw fixing plate 5 is arranged on the rubber sleeve 2; the screw fixing plate 5 is provided with a through hole 7; the screw fixing plate 5 is fixedly connected with the rubber sleeve 2 and the aluminum pipe 4 through screws.

Referring to fig. 1-3, in the present embodiment, an aluminum pipe 4 is welded to a flange 1, a rubber sleeve 2 with a corresponding specification is sleeved outside the aluminum pipe 4, a screw fixing plate 5 is sleeved outside the rubber sleeve 2, the screw fixing plate 5 is installed at a position corresponding to a groove 9 formed in the aluminum pipe 4, the screw fixing plate 5 is screwed by a screw 8, the rubber sleeve 2 is clamped into the groove 94 and fixed on the aluminum pipe, and thus the device is started to operate, water flows out from a water outlet 3 of the aluminum pipe 4 and flows out to two ends of the rubber sleeve 2, and the two ends of the rubber sleeve 2 are not communicated with each other.

In the embodiment described with reference to fig. 4-7, an aluminum pipe 4 is welded on a flange 1, then a rubber sleeve 2 is wound around the aluminum pipe 4, then the joint of the rubber sleeve 2 is fixed in the aluminum pipe 4 2, then a screw fixing plate 5 is installed at the joint of the rubber sleeve 2, then the screw fixing plate 5 and the rubber sleeve 2 are directly and fixedly installed in a groove 9 of the aluminum pipe 4 through a screw 8, when the device starts to operate, water flows out from a water outlet 3 of the aluminum pipe 4 and flows out to two ends of the rubber sleeve 2, and the two ends of the rubber sleeve 2 can be communicated with each other.

The utility model discloses an operating process at first carries out welded fastening with flange 1 and aluminum pipe 4, sets up a plurality of recess 3 on the aluminum pipe 4, and when 4 sizes of aluminum pipe are less, embolia rubber sleeve 2 in the outer end of aluminum pipe 4, then at 2 externally mounted screw fixation boards of rubber sleeve 5, then carry out fixed connection with screw fixation board 5 and rubber sleeve 2 and aluminum pipe 4 through the screw, at last through flange 1 and body 4 looks fixed connection. When the aluminum pipe 4 is large in size, rubber is rolled on the outer portion of the aluminum pipe 1 to form the rubber sleeve 2, then a screw fixing plate 5 is installed on the outer portion of the rubber sleeve 2, then a through hole 7 in the screw fixing plate 5 is aligned with a screw through hole 6 in the rubber sleeve 2 and a screw hole in the aluminum pipe 4, then the screw fixing plate 5 is fixedly connected with the rubber sleeve 2 and the aluminum pipe 4 through a screw 8, water is supplied after installation is completed, water enters an inner hole 401 of the aluminum pipe 4 through a water inlet 101 of the flange 1 and then flows out through a groove 3 formed in the aluminum pipe 4, the water can directly flow from two ends of the rubber sleeve 2, and the pressure of the water on the rubber sleeve 2 is reduced.

The check valve has the beneficial effects that the check valve is simple in result and convenient to use, the rubber sleeve 2 which is communicated with the two ends is arranged on the aluminum pipe 4, when the check valve is used, the rubber sleeve 2 is tightly arranged on the aluminum pipe 1 by the screw, water can directly flow from the two ends of the rubber sleeve 2, the pressure of the water on the rubber sleeve 2 is reduced, the check valve is only connected by the screw, the check valve is more convenient to replace, and the service life is longer; by installing the screw fixing plate 5 on the rubber sleeve 2, the screw fixing can be facilitated, and the sliding is prevented.
