Example Embodiment

[0019] The preferred embodiments of the water supply plug of the present invention will be described below with reference to Figures 1 to 3.

[0020] A water supply plug includes a plug body. The plug body includes a columnar upper valve body 1, a lower valve body 2 connected to the upper valve body 1, and a valve port 3 located between the upper valve body 1 and the lower valve body 2. The upper valve body 1 and the lower valve body 2 are integrally formed.

[0021] A crankshaft mechanism 4, a rotating handle 5 and a connecting rod 6 mounted on the crankshaft mechanism 4 are mounted on the upper end of the upper valve body 1. The rotating handle 5 drives the crankshaft mechanism 4 to rotate; then the crankshaft mechanism 4 drives the connecting rod 6 to reciprocate vertically.

[0022] The crankshaft mechanism 4 includes a first shaft 7 mounted on the upper valve body 1, a second shaft 8 connected with the rotating handle 5, and a third shaft connected with the first shaft 7 and t...

Abstract

The invention provides a water supply hydrant. The water supply hydrant comprises a hydrant body, a connecting rod and a valve rod which are mounted on the hydrant body, and a valve core mounted on the valve rod, wherein the hydrant body comprises an upper valve body, a lower valve body connected with the upper valve body, and a valve port positioned between the upper valve body and the lower valve body; the connecting rod is mounted on the upper valve body; the valve rod is mounted on the lower valve body; an elastic part below the valve core is arranged on the valve rod in a sleeving manner; the valve core, the valve port and the valve rod are in seal fit; and the connecting rod can be propped against the valve rod and the valve core, and can drive the valve rod and the valve core to perform reciprocating motion in the vertical direction. According to the water supply hydrant, driving force required during the entire valve opening process is reduced, the operation is convenient and quick, and the service life of the water supply hydrant is prolonged.

Description

technical field [0001] The invention relates to the field of valves, in particular to a water supply cock. Background technique [0002] The existing water supply cock includes a cock body and a valve arranged in the cock body. The valves are mostly check valves or globe valves. This series of valves is placed in the plug body and has a large contact area with the water flow, so the area under the action of water pressure is relatively large, which will increase the driving force of the valve opening, which is time-consuming and labor-intensive. It will also increase the wear of the valve and reduce the service life of the valve. [0003] In view of this, it is necessary to design a water supply cock to solve the above problems. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a water supply cock that can be opened conveniently and quickly. [0005] In order to achieve the above object, the present invention p...
