Abstract
The utility model discloses a fire hydrant with a drainage device. The fire hydrant comprises a hydrant body, wherein the bottom of the hydrant body is provided with a water inlet and a valve seat, and a valve rod is installed in the hydrant body. The front end of the valve rod is provided with a valve clack, and the upper part of the hydrant body is provided with a plurality of water outlets. Breather valves are respectively installed at the water outlets. One side of the valve seat is provided with a drainage port which is connected with a drainage pipe, and the combining part of the drainage port and the drainage pipe is provided with a drainage valve. The drainage valve comprises a cylindrical valve body, and a step hole is arranged in the cylindrical valve body. A steel ball is put in the step hole, and a spring is arranged between the bottom of the steel ball and the step face of the step hole. O-shaped seal rings are respectively between the cylindrical valve body and the drainage port and between the steel ball and the step face of the step hole, and the breather valves are elastic component. With a reasonable structure, the fire hydrant ensures that fire water in the fire hydrant cannot be leaked when the fire hydrant is opened to use and can ensure that residual water in the fire hydrant can be quickly released when the fire hydrant is closed.
Description
Technical field
The utility model relates to hydrant, specifically is a kind of hydrant that has dewatering installation.
Background technology
The hydrant of selling in Chinese market at present, by the GB4452 requirement, " hydrant should be equipped with the device of the surplus water of automatic discharging, and when hydrant was in normal use (full open) state, the seepage phenomenon must not take place this device ".After standard was not closed hydrant, the drain function of this device was done detail requirement.Therefore, the hydrant dewatering installation on the domestic market is all simple in structure, function singleness, and after hydrant used, all outlet ports was closed, and hydrant inside gets into because of no air, and ponding just can't be discharged.The inner long-term ponding of hydrant can cause key corrosion, polluted source; Can be destroyed because of the ponding freezing and expansion causes hydrant when it is cold in addition.
The utility model content
The purpose of the utility model provides a kind of hydrant that has dewatering installation.
The utility model technical scheme is following:
A kind of hydrant that has dewatering installation includes key, and the bottom of said key is provided with water inlet and is provided with valve seat; In the said key valve rod is installed, said valve rod front end is equipped with flap, it is characterized in that: the top of said key is provided with several delivery ports; Said several delivery port places are equipped with breather valve respectively, and said valve seat one side is provided with outfall and is connected with gutter, and the joint portion of said outfall and gutter is provided with draining valve; Said draining valve comprises the tubular valve body; The inside of said tubular valve body is provided with stepped hole, is placed with steel ball in the said stepped hole, is provided with spring between the bottom of said steel ball and the step surface of stepped hole; Be respectively equipped with the O RunddichtringO between said tubular valve body and the outfall and between the step surface of steel ball and stepped hole, said breather valve is a rubber-like part.When hydrant valve was opened, when hydraulic pressure raise slightly in the key, the steel ball extrusion spring outwards moved in the draining valve; Promptly close behind the contact O RunddichtringO; Meanwhile, the flap of breather valve is also closed rapidly under hydraulic action, and hydrant just can leak freely supply water to delivery port this moment.When hydrant valve and each delivery port are closed; Steel ball leaves the O RunddichtringO in the draining valve under the effect of spring force; Form a delivery port; The externally atmospheric effect of the flap of breather valve is opened rapidly down, destroys hydrant inner chamber vacuum, cooperates draining valve at short notice the surplus water of hydrant inner chamber to be arranged.
The utility model beneficial effect:
The utility model is rational in infrastructure; Guaranteed that hydrant its inner water for fire when opening use does not leak; When hydrant cuts out; Can guarantee that the inner remaining ponding of hydrant is released fast, the key corrosion of having avoided the inner long-term ponding of hydrant to cause causes the ruined phenomenon of hydrant because of the ponding freezing and expansion when polluted source and sky are cold.
