Detailed Description
The invention is further described below with reference to the accompanying drawings:
examples
A damp-proof underground fire hydrant, as shown in figure 1, comprises a hydrant body 1, a water outlet hydrant 2, a water inlet hydrant 3, a valve rod 4, a valve body 5, a valve seat 6 and a drain valve 7; the bolt body 1 is fixedly connected to the top of the valve seat 6 and is communicated with the interior of the valve seat 6; the drain valve 7 is fixedly connected to the valve seat 6 and is communicated with the interior of the valve seat 6; the valve body 5 is clamped with the inner wall of the bolt body 1; the valve rod 4 is fixedly connected with the valve body 5 and penetrates through the valve body 5 to extend outwards; the water inlet bolt 3 and the water outlet bolt 2 are fixedly connected to the top of the bolt body 1 in sequence; the outer surface of the bolt body 1 comprises a zinc spraying layer 8, a rust removing paint layer 9, a heat insulation resin layer 10 and a scratch-proof film 11; the zinc spraying layer 8 is sprayed on the outer surface of the bolt body 1; the rust removing paint layer 9 is sprayed on the outer surface of the zinc spraying layer 8; the heat insulation resin layer 10 is coated on the outer surface of the derusting paint layer 9; the scratch-resistant film 11 covers the heat insulating resin layer 10.
The valve body 5 is connected with an external pipeline in a flange connection mode.
And the water outlet bolt 2 and the water inlet bolt 3 are both provided with connecting chains.
The scratch-resistant film 11 is composed of wear-resistant polyurethane with a layered structure, a transparent PET safe base layer and a composite adhesive, and can resist friction damage caused by normal scrubbing.
The material of the rust removing paint layer 9 is polyurethane resin.
After the underground fire hydrant is installed underground, water can be conveyed through an external fire pipeline, the water inlet hydrant 3 and the water outlet hydrant 2 are matched to enter and exit water, the water is closed through the valve body 5, the valve rod 4 can control the valve body 5 to be opened, the drain valve 7 can drain redundant water after the valve body 5 is closed, the valve seat 6 is connected with the external fire pipeline, when the underground fire hydrant is in humid weather or rainstorm weather, the hydrant body 1 of the underground fire hydrant is easily exposed and corroded by moisture and rainwater, the oxidation speed of the hydrant body 1 can be accelerated by long-time corrosion, the service life of the underground fire hydrant is influenced, therefore, the zinc-spraying layer 8 is coated on the hydrant body 1, thin zinc containing ninety percent of pure zinc can be formed after the zinc-spraying layer 8 is coated, the electroplating effect is like, the oxidation resistance and the corrosion resistance are improved, then, the rust-removing paint layer is coated outside the zinc-spraying layer 8, and the rust-proof paint can further effectively prevent the hydrant, further improve corrosion resistance, because the underground fire hydrant is used to cold areas more, avoid the water in the underground fire control pipeline to freeze and can't carry out fire control work, consequently scribble thermal-insulated resin outside the rust cleaning paint layer, thermal-insulated resin not only can avoid the influence that the high temperature caused the fire hydrant, also can completely cut off outside cold simultaneously, avoid the underground fire hydrant to receive and freeze, and thermal-insulated resin coats still outward and has the one deck to prevent scraping film 11, prevent scraping film 11 and can avoid receiving sharp article scratch thermal-insulated resin such as stone in the installation or in the use, rust cleaning paint layer and spout zinc layer 8, provide certain protecting effect to bolt 1, bolt 1 through multilayer protective action, can increase of service life, also can be convenient for come into use in cold areas simultaneously.
Although the present disclosure has been described in detail with reference to the exemplary embodiments, the present disclosure is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes can be made thereto without departing from the scope of the present disclosure.
