Description
Technical field
The utility model relates to a kind of fire services installations, particularly a kind of underground hydrant.
Background technology
The kind of hydrant can be classified by following several situation substantially, arranges and divides substantially: indoor fire hydrant and outdoor fire hydrant by hydrant.Ground type, underground type, direct burial telescopic can be divided into again by outdoor fire hydrant installation form.Single port formula, dual-opening type and three outlet types etc. are divided by nozzle outlet number.
Outdoor fire hydrant is arranged on the water facilities outside building on fire water supply pipe network, the main fire fighting truck that supplies implements fire extinguishing from municipal water supply pipe network or the water intaking of outdoor fire fighting waterline network, also directly can connect water-band, hydraulic giant goes out above-water method, be one of important fire fighting device fought a fire.
Current outdoor fire hydrant requires remained water discharge function, and will remaining scale be caused to lose capital body and key internal part if remained water discharge does not go out, when cold, the remaining water capacity be easily frozen, and causes key bursting by freezing.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of underground hydrant of remaining water energy automatic-discharging.
The utility model realizes like this, a kind of underground hydrant, it mainly comprises base, water inlet bend pipe, body, key, intake, valve rod, extension bar, flap and Yu Shui draining valve, intake be vertically towards, it is characterized in that being provided with remaining water draining valve on the body above valve seat, remaining water draining valve is by remaining water draining valve valve body, glass marble, circlip for hole, circular seal ring, spring and Yu Shui outfall composition, glass marble is positioned in valve body, both sides are circlip for hole and circular seal ring respectively, spring is provided with between glass marble and Yu Shui outfall.
Described water inlet bend pipe and base are connected, and are connected with the body of top by bend pipe bolt, and corner sealing gasket is equipped with in bend pipe and body junction.
Described body is funnel-form, and bell mouth place in the middle part of body arranges valve seat, is connected by body bolt with the key of top, and this body sealing ring is equipped with in body and key junction.
Described key is hemispherical, and install valve rod in the middle of above key, periphery is provided with several intakes, has intake to cook lid above intake, and kitchen lid sealing ring is equipped with in intake kitchen lid and intake junction.
On described valve rod, cover has valve gap, valve stem packing ring and valve plate, and valve gap is by valve gap bolt, valve bonnet seal pad and the airtight connection of key; Valve plate is connected with the valve gap of top by screw; Between valve rod and valve gap, valve stem packing ring is housed; Valve rod is connected with the threaded engagement of stem connector by valve rod screw.
Described stem connector is connected with the extension bar of below by extension bar latch.
Connect the flap seal pad below lobe, lobe below described extension bar, flap base plate is fixed on bottom lobe by flap bed bolt.
The principle of remaining water draining valve is: when using hydrant, when lobe on body valve seat is mentioned by extension bar, the water in bend pipe enters body, and the glass marble in remaining water draining valve is due to intrinsic hydraulic pressure effect, outside movement against the force of the spring, withstand the circular seal ring of draining valve; After hydrant uses, flap is pressed down by extension bar and gets back to valve seat, flap seal pad and valve seat airtight, water in bend pipe is cut off, in body, hydraulic pressure reduces, when spring resistance is greater than the pressure of water in body, glass marble moves to circlip for hole side under the action of the spring, and Yu Shui is discharged from outfall by the space between glass marble and circular seal ring.
The beneficial effects of the utility model are, it is stable and reliable for performance, durable that it has remaining water Auto-drainage, adopt the advantages such as glass marble can not get rusty.
