Embodiment Construction

[0038] Such as Figure 1 to Figure 15 As shown, the self-exhausting lifting water supply hydrant includes an elbow 1 , an inner pipe 2 , a gland 3 , an outer pipe 4 and a bottom bracket 5 .

[0039] The elbow is connected to the inner pipe 6, and the connection method of the two can be one of screw connection, quick chuck connection, bonding or flange connection. Such as Figure 15 As shown, the elbow and the inner pipe are integrally formed, either by integral injection molding or other methods. Such as Figure 2 to Figure 4 As shown, the elbow 1 includes an elbow housing 101, and a snap ring 102 is provided at the outlet end of the elbow housing 101 for fixing the water pipe. A quick chuck 103 is provided at the lower end of the elbow shell 101, and a block is provided inside the quick chuck 103. The quick chuck 103 matches the clip strip on the upper part of the inner tube, and the elbow and the inner tube can be realized by rotating the elbow. The card is tight.

Abstract

The invention provides a self-exhausting lift type hydrant and relates to the technical field of water conservancy equipment. The self-exhausting lift type hydrant comprises an elbow, an inner pipe, a gland, an outer pipe and a bottom support, wherein the elbow is connected with the inner pipe; the inner pipe moves in the outer pipe; the gland is arranged at the upper end part of the outer pipe; the outer pipe is connected with the bottom support; an exhausting valve is arranged on the bottom support; the exhausting valve comprises an outer mounting shell; a limiting part is arranged on the outer mounting shell; an elastic sealing body for allowing water flow to pass through is arranged at the upper part of the outer mounting shell; a floating ball is arranged between the limiting part and the elastic sealing body; and the floating ball is capable of floating upwards to block a water outlet in the elastic sealing body. By virtue of the design of the exhausting valve, the self-exhausting lift type hydrant provided by the invention is capable of eliminating the water hammer phenomenon; by adopting a valve composite component, the problem of the poor sealing effect of a rubber ring is prevented; the self-exhausting lift type hydrant is simple in structure, convenient to open and close, scientific in manufacturing process, economical, practical, and widely applicable to farm irrigation, water supply and water draining of urban green lands.

Description

technical field [0001] The invention relates to the technical field of water conservancy equipment, in particular to a self-exhausting lift-type water supply cock. Background technique [0002] The structure of the existing water supply on-off valve is relatively complicated, and some have iron metal parts, which are easy to corrode, and even the seal is not tight, and it is easy to leak. [0003] Chinese patent CN105570469A discloses a fluid on-off valve, which realizes the on-off of the fluid by squeezing the sealing ring on the valve tube and the valve seat. But there are also some problems. [0004] First, as the valve pipe and the sealing ring continue to rub back and forth, the bolts and the sealing ring become loose, resulting in the reduction or failure of the sealing effect of the fluid switching valve; [0005] Second, bolts are used to fix the conical table. After long-term soaking in running water, the bolts are seriously corroded, and the original intention of...
