Embodiment Construction

[0026] Such as Figure 1 to Figure 10 As shown, the lifting opening and closing type water supply cock includes an elbow 1, an inner pipe 6, an outer pipe 3, a gland 2 and a bottom support 4, and the elbow 1 is connected with the inner pipe 6, which is more optimally designed. The connection method of the inner pipe is one of screw connection, quick chuck connection, bonding or flange connection.

[0027] The elbow 1 and the inner pipe 6 can be arranged as a split structure, such as Figure 8 shown. The elbow 1 can be unscrewed and taken away to avoid being stolen, and the inner tube 6 can be provided with a cover 10 to seal the inner tube mouth and prevent foreign matter from entering.

[0028] The inner tube 6 moves inside the outer tube 3 , and the upper end of the outer tube 3 is provided with a gland 2 for sealing between the inner tube 6 and the outer tube 3 .

[0029] Further, a sealing ring 9 is provided between the outer tube 3 and the gland 2, and the sealing ring...

Abstract

The invention provides a lifting and switching-on and switching-off type hydrant and relates to the technical field of water conservancy equipment. The lifting and switching-on and switching-off type hydrant comprises a bend, an inner pipe, an outer pipe, a pressing cover and a cork base. The bend is connected with the inner pipe, the inner pipe moves in the outer pipe, the upper end of the outer pipe is provided with the pressing cover, the outer pipe is connected with the cork base, the cork base is provided with a valve boss, the lower end of the inner pipe is provided with a valve composite part, and a valve is switched on or off through separation and reunion of the valve boss and the valve composite part. The hydrant is simple in structure, convenient to switch on or off, scientific in manufacturing process, economical and practical and can be widely applied to farm irrigation, urban green land and water supply and discharge and the like. By using the hydrant, lifting, switching-on, switching-off and omni-directional rotation can be performed, functions of invisibility and anti-collision and the like can be achieved by matching with a protective device for use, and the hydrant is practical, economic and advanced.

Description

technical field [0001] The invention relates to the technical field of water conservancy equipment, in particular to a lifting and closing 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. 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 switch valve; second, the bolts are used to fix the conical table. This method is soaked in running water for a long time. The bolts are seriously corroded, which has lost the original inten...
