Abstract
The utility model relates to an automatic control draining structure for a fire hydrant, which comprises a valve body of a fire hydrant. The utility model is characterized in that the side of the bottom part of a piston motion channel of the valve body of a fire hydrant is provided with a draining port; the outside of the draining port is provided with a valve seat and a moving valve core positioned in a through hole of the valve seat; the moving valve core comprises a valve rod and a valve lead which is connected with the inside of the valve rod and is used for opening and closing the draining port; the inner diameter of a working chamber of the valve lead is larger than the outer diameter of the valve lead; the working chamber of the valve lead is communicated with a draining channel communicated with the outside; the moving valve core is connected with a pressing spring elastic force regulating seat arranged in the through hole of the valve seat via a reset pressing spring arranged on the top part of the valve rod. The utility model has the functions of automatic drainage, automatic return, and automatic positioning and sealing.
Description
Technical field: the utility model relates to a kind of fire hydrant automatic control discharge structure.
Prior art: because the piston valve top of present employed fire hydrant has one section cavity, making usually has many ponding to discharge in the cavity, and when winter weather cold, the ponding in the cavity freezes, and makes piston to move, and fire hydrant can not use.
Summary of the invention: the purpose of this utility model provides the fire hydrant automatic control discharge structure of a kind of draining automatically, self-return and automatic positioning seal.
The utility model is to constitute like this, it comprises the fire hydrant valve body, it is characterized in that: the piston moving conduit bottom side of fire hydrant valve body is provided with discharge outlet, the movable spool that this discharge outlet outside is provided with valve seat and is positioned at valve seat through-hole, described movable spool comprise valve rod and with the joining valve that is used to open and close discharge outlet of valve rod inner end, valve working chamber internal diameter is greater than the valve external diameter, the valve working chamber is connected with the drainage of leading to the outside, and movable spool links by the reseting pressuring spring of being located at the valve rod top and the stage clip elastic force adjustment seat of being located in the valve seat through-hole.
When more ponding is arranged at the piston moving conduit bottom of fire hydrant valve body, will move to the valve seat direction by promotion activity spool, thereby discharge outlet is opened, because the effect of liquid pressure, ponding promotion activity spool moves to the valve seat direction, thereby discharge outlet is opened, and discharges ponding.After ponding had been arranged, pressure reduced, and movable spool just is returned to the origin-location under the effect of reseting pressuring spring elastic force, made the discharge outlet sealing.
The utility model is simple in structure, and simple operation has good drain function.
Description of drawings: Fig. 1 is the utility model embodiment organigram,
Fig. 2 is the local enlarged diagram of drain valve structure among Fig. 1,
Fig. 3 is the concrete structure schematic diagram of valve rod,
Fig. 4 is the cutaway view of Fig. 3.
The specific embodiment: the utility model embodiment comprises fire hydrant valve body 1, it is characterized in that: the piston moving conduit 2 bottom sides of fire hydrant valve body are provided with discharge outlet 3, the movable spool 5 that this discharge outlet outside is provided with valve seat 4 and is positioned at valve seat through-hole, described movable spool comprise valve rod 6 and with the joining valve 7 that is used to open and close discharge outlet of valve rod inner end, valve working chamber 8 internal diameters are greater than the valve external diameter, the valve working chamber is connected with the drainage of leading to the outside, and movable spool links by the reseting pressuring spring 9 of being located at the valve rod top and the stage clip elastic force adjustment seat of being located in the valve seat through-hole 10.
Above-mentioned stage clip elastic force adjustment seat is to be located at the screwed pipe that the interior middle part of valve seat tapped through hole has drainage hole 11, and valve rod is provided with the water stream channel 12 that the valve working chamber is connected with the drainage hole of screwed pipe.
The outer end of above-mentioned valve rod is provided with the duct that is connected with the drainage hole of screwed pipe, and the duct is provided with the through hole that is connected with the valve working chamber diametrically.
When more ponding is arranged at the piston moving conduit bottom of fire hydrant valve body, will move to the valve seat direction by promotion activity spool, thereby discharge outlet is opened, when discharge outlet is opened, ponding in the fire hydrant enters the valve working chamber through discharge outlet, and the drainage hole by water stream channel on the valve rod and screwed pipe is discharged to the outside then.After ponding had been arranged, pressure reduced, and movable spool just is returned to the origin-location under the effect of reseting pressuring spring elastic force, made the discharge outlet sealing.
Between above-mentioned valve rod and the valve thread connection, and by nut 13 lockings.
Be provided with sealing plate 14 between the above-mentioned valve and the circular bead surface of valve rod.
Be provided with sealing gasket 15 between above-mentioned valve seat and the fire hydrant valve body.
The utility model is simple in structure, and simple operation has good drain function, can guarantee that fire hydrant also normally used in the season of cold, and its application prospect is very considerable.
