Description

A kind of fire plug
Technical field
The utility model relates to a kind of fire plug, particularly relates to the fire plug that a kind of water tender is special.
Background technology
At present, the special fire plug of known water tender is all adopt the valve seat of flap or valve plate and bottom to dam, flap is circular blade shape, it mainly implements rotating closed with unlatching by the rotation of valve rod, it is this that to set up one be that flap belongs to three-dimensional rotation and dams, its resistance be subject to is large, and not only lobe face is yielding, and the phenomenon of falling apart also often is arranged at bottom; Two to be that valve rod stretches downwards oversize, and transport power is not enough; Valve plate belongs to mandatory and dams, and its operational mode is from top to bottom or from lower to upper, and this to set up one be plate body thickness low LCL, and its outer ring body easily weares and teares, and often has leakage phenomenon; Two to be that valve rod stretches downwards oversize, and transport power is not enough, often causes screw thread stripped thread or the fracture on valve rod top.
Summary of the invention
In order to overcome the in use existing deficiency of existing fire plug, the utility model provides a kind of fire plug, does not arrange valve seat bottom this fire plug, is directly rotated by valve rod and starts rotating disk, then dammed by the nethermost plug that dams.
The utility model solves the scheme that its technical problem adopts: comprise stopper and key, the arc-shaped upper ends face middle part of stopper digs wears a circular openning, the annular side of stopper bottom stretches out along horizontal respectively, and be arranged to fixing surrounding edge, fixing surrounding edge surface penetrates screw respectively, the upper and lower annular outboard of key stretches out along horizontal respectively, and be arranged respectively to fixing surrounding edge, the surface of upper and lower two fixing surrounding edges penetrates screw respectively, stopper bottom is fixed the screw that the screw on surrounding edge fixes on surrounding edge with key top respectively and is alignd, waist place, key side half digs and wears a circular openning, and be arranged to delivery port, the cylindrical cavity of key center is valve pit, screw thread is arranged on the inner ring body top of valve pit, the delivery port at waist place, key side half is communicated with in valve pit cavity, the water inlet of valve pit bottom connects water source, the annular ectosome starting rotating disk is arranged to screw, start disc surfaces middle part and penetrate a round hole, valve rod is cylindrical, the lower end of valve rod is through starting the round hole of rotating disk middle part to downward-extension, the surperficial middle part beyond the Great Wall and welding is dammed, valve rod is through starting the space, round hole of rotating disk tow sides middle part by electric welding seal welding, during installation, first the plug that dams of stem lower portion is embedded in valve pit, arrive that section of starting rotating disk just to start down to rotate in positive direction, and make the screw of starting rotating disk outer ring body screw up the screw thread on valve pit cavity inner ring body top, stopper covers the top of key, valve rod upper end is through the circular openning of stopper top middle part, and weld rotary disk shutter reverse side middle part, the fixing surrounding edge of stopper bottom aligns with the fixing surrounding edge on key top, and fixed by screw rod, the fixing surrounding edge of key bottom is fixed with the ground installation of corresponding position respectively by screw rod.
The beneficial effects of the utility model are, dam plug inside set up by smart steel, whole outside is set up by top-quality rubber material, the outer ring body filled in that dams directly contacts valve pit cavity inner ring body, its mode of damming is: drive to dam by the valve rod on top and the rotation of starting rotating disk and fill in, start rotating disk down to rotate and will dam, start rotating disk up to rotate and will open water source, the screw starting rotating disk outer ring body screws up mutually with the screw thread of valve pit cavity inner ring body, because the area starting the rotation of rotating disk outer ring body is larger, its upper and lower parcel rotation one can make up the transport power deficiency that valve rod brings because of length, also make valve rod change into compliance from mandatory rotation to rotate simultaneously, two can produce powerful driving effect to lower operation beyond the Great Wall of damming.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
In Fig. 1, comprise stopper and key, the arc-shaped upper ends face middle part of stopper 3 digs wears a circular openning, the annular side of stopper 3 bottom stretches out along horizontal respectively, and be arranged to fixing surrounding edge 6, fixing surrounding edge 6 surface penetrates screw 10 respectively, the annular outboard of key about 4 stretches out along horizontal respectively, and be arranged respectively to fixing surrounding edge 6, the surface of upper and lower two fixing surrounding edges penetrates screw 10 respectively, and stopper 3 bottom is fixed the screw 10 that the screw 10 on surrounding edge 6 fixes on surrounding edge 6 with key 4 top respectively and alignd.
Stopper 3 covers the top of key 4, valve rod 2 upper end is through the circular openning of stopper 3 top middle part, and weld rotary disk shutter 1 reverse side middle part, the fixing surrounding edge 6 of stopper 3 bottom aligns with the fixing surrounding edge 6 on key 4 top, and fixed through screw 10 by screw rod 7, the fixing surrounding edge 6 of key 4 bottom is fixed with the ground installation of corresponding position respectively by screw rod 7.
Fig. 2 comprises Fig. 1, screw thread is arranged on the inner ring body top of valve pit 12, the delivery port 5 at waist place, key 4 side half is communicated with in valve pit 12 cavity, the water inlet 8 of valve pit 12 bottom connects water source, the annular ectosome starting rotating disk 11 is arranged to screw, start the surperficial middle part of rotating disk 11 and penetrate a round hole, the lower end of valve rod 2 through starting the round hole of rotating disk 11 middle part to downward-extension, and welds the plug 9 upper surface middle part that dams.
During installation, first the plug 9 that dams of valve rod 2 bottom is embedded in valve pit 12, arrived that section of starting rotating disk 11 and just started down to rotate in positive direction, and made the screw of starting rotating disk 11 outer ring body screw up the screw thread on valve pit 12 cavity inner ring body top.
