Abstract
The utility model relates to a low pressure rotating sealed plastic water outlet hydrant which is simple in structure, difficult to damage, easy and convenient to operate, and good in sealing effect. The low pressure rotating sealed plastic water outlet hydrant comprises a water outlet hydrant body, a sealing core, a water sealing cover and a rotating shaft, wherein joints of all the components are provided with sealed structures, one side of the water outlet hydrant body is open, the sealing core with one side open is sleeved in the water outlet hydrant body, a clamping groove matched with the rotating shaft is arranged on the upper portion of the sealing core which can rotate freely, and the shaft of the rotating shaft extends out of the center hole of the water sealing cover which is arranged on the upper opening of the water outlet hydrant body. External forces act on the rotating shaft, and the sealing core is driven to rotate, and therefore the water outlet hydrant body and the sealing core are sealed in rotating mode.
Description
Technical field
The utility model belongs to the hydrotechnics field, is specifically related to a kind of water outlet bolt.
Background technique
The water outlet bolt is an important component part of farmland water-saving irrigation system, usually, the water outlet bolt all is comprised of the rise-fall type sealing mechanism, and the water outlet bolt of this type easily damages in descending operation active force lower seal part and main body in the market, thereby cause leakage, do not have permanent sealability.
Summary of the invention
The utility model provides a kind of low pressure rotary sealing type plastics water outlet bolt of simple in structure, not fragile, easy and simple to handle, good sealing effect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of low pressure rotary sealing type plastics water outlet bolt is provided, comprise water outlet bolt main body, sealed core, water seal cover, rotating shaft, each parts joint is provided with sealing configuration, described water outlet bolt main body is a side opening, the sealed core cover of one side opening is received in the water outlet bolt main body, and the sealed core top that can freely rotate is provided with the draw-in groove that matches with rotating shaft, and the shaft extension of rotating shaft goes out to be arranged on outside the center hole of water outlet bolt main body water seal cover suitable for reading.External Force Acting drives the sealed core rotation, thereby makes water outlet bolt main body and sealed core rotary seal to rotating shaft.
Further, described water outlet bolt main body is hollow cylinder, and described sealed core is cylindric, the two cooperation.
Further, the water outlet of described water outlet bolt main body is provided with the location bone, and the sealed core opening is provided with annular projection, is provided with out waterstop ring around annular projection.Especially, described location bone has three circles.During the sealed core rotation, described location bone can be used the smooth transition of waterstop ring and do not come off.
Further, described sealed core bottom and top are respectively equipped with seal groove, are provided with large O RunddichtringO between seal groove and the water outlet bolt main body.Especially, described seal groove has 2 circles, and large O RunddichtringO and water outlet bolt main body inner wall are matched, and forms double leak-proof.
Further, be provided with the L-type seal ring between water seal cover and the water outlet bolt main body, water seal cover is provided with the gear of clamping L-type seal ring at sealing station, so that the suitable for reading and water seal cover tight seal of water outlet bolt main body.Also gapped between the gear of water seal cover and the sealed core, do not affect the sealed core rotation, can also play the position-limiting action that makes sealed core not move up and down.
Further, the center hole of water seal cover is provided with the location bone and is deep in the draw-in groove, prevents that rotating shaft breaks away from draw-in groove.
Further, the center hole of water seal cover is provided with locking nut, is provided with little O RunddichtringO between locking nut and the water seal cover, and water is revealed when avoiding the rotating shaft rotation.
Compared with prior art, beneficial effect is:
1, the low pressure rotary sealing type plastics water outlet bolt that provides of the utility model is simple in structure, can realize rotary seal by simple action, and is easy to use.
2, the low pressure rotary sealing type plastics water outlet bolt that provides of the utility model drives sealed core by rotating shaft and cooperates the realization simple motion with realization rotary seal with water outlet bolt main body, and is stressed little between the parts, not fragile, greatly prolonged its working life.
3, the low pressure rotary sealing type plastics water outlet bolt that provides of the utility model by various sealing configurations, has effectively been realized the sealing in the working procedure.
