Description
Technical field
The utility model relates to a kind of fire-fighting equipment, and is particularly a kind of by the above that can not leak after hitting.
Background technology
Along with China's rapid economy development; The property loss that fire causes is also increasing; Governments at all levels have further strengthened the element task of security against fire for this reason; The supporting fire-fighting infrastructure in residential quarter, market town, industrial and mining enterprises and public place is gradually improved, and in traffic convenience and important place an amount of above has been installed all, for security against fire is laid a good foundation.Existing above is made up of cover cap, upper bolt, middle key, lower bolt, action bars, spool, valve seat, and the water outlet interface is arranged on the upper bolt, when running into the condition of a fire, screws action bars and can open valve, implements fire extinguishing; But not enough below also existing: the one, above generally is installed in fire-fighting vehicle turnover place comparatively easily; Therefore public vehicles are current has constituted grave danger to above, and mistake is bumped, the mistake accident of hitting occurs repeatedly, and is hit late gate and is in open state; A large amount of tap water are gushed from lower bolt; So not only cause the water resource serious waste, masses' trip brings inconvenience around giving, and influences traffic safety; And water supply line need reduce pressure or cut off the water during maintain and replace, causes the normal water of user in the water supply line scope.The 2nd, distance is long between action bars and the valve seat, walks about easily when causing valve closing and leaks, and sealing effectiveness is undesirable.For this reason, many manufacturers and knowledgeable people have carried out the R and D of fruitful ground, but do not have rational product to emerge so far as yet.
Summary of the invention
In order to overcome the above-mentioned disadvantage that existing above exists, the purpose of the utility model provide a kind of simple and reasonable, good reliability, easy to maintenance, break the water-tight crashproof fire plug in back.
The utility model solves the technical scheme that its technical problem adopted, and its said fastener comprises nut, screw rod, abnormity nut, and abnormity nut is provided with to what extended both sides and helps to shoulder heavy thing; Vertically be provided with groove button upwards; Form cannelure between upper bolt and the valve seat, the U type notch that is arranged on the upper bolt links to each other with cannelure, screw rod pass U type notch and be connected upper bolt and valve seat between; Nut is fixed on the top of screw rod; Abnormity nut is fixed on the bottom of screw rod, helps to shoulder heavy thing to be connected between the upper bolt and valve seat of cannelure both sides, and the groove button is buckled in the cannelure.
In order when bump takes place, to play the effect of protection upper bolt better, described screw rod is provided with the groove that contracts.
Screw mandrel separates with action bars for ease; And prevent that screw mandrel and action bars from squinting all around, and being fixed with the guide pin bushing support on the described valve seat, the guide pin bushing carriage center is provided with rotating guide pin bushing; The guide pin bushing axial location is on the guide pin bushing support; Spool cooperates with valve seat and is connected with screw mandrel, and screw mandrel is connected on the guide pin bushing through threaded engagement, and action bars bottom and guide pin bushing flexibly connect.
For straight line about guaranteeing spool and screw mandrel moves, described valve seat is provided with guide groove, and spool is provided with prerotation vane, and prerotation vane is arranged in the guide groove.
Install for ease, described valve seat is fixed with Connection Block.
After adopting said structure, following advantage and effect are arranged compared with prior art: the one, abnormity nut produces and is out of shape when bump, and bolt and abnormity nut are deviate from from U type notch, can not damage upper bolt, only need change bolt during repairing and abnormity nut gets final product; The 2nd, spool is fixed on the screw mandrel; Screw mandrel is connected on the guide pin bushing through threaded engagement; Action bars bottom and guide pin bushing flexibly connect, even upper bolt is severed, action bars separates with guide pin bushing immediately automatically; Do not influence the valve closing state, thereby avoid the waste of water resource and the inconvenience of bringing for surrounding environment; The 2nd, after distance shortens greatly between screw mandrel and the valve seat, valve seal better effects if, more difficult leaking.

The specific embodiment
Fig. 1 is the embodiment of the crashproof fire plug of the utility model to shown in Figure 6, and it comprises cover cap 1, upper bolt 6, action bars 5, spool 13, valve seat 12; Upper bolt 6 is provided with fixed head 2, and action bars 5 tops are by fixed head 2 sealing location, and upper bolt 6 is fixedly connected through fastener 9 with valve seat 12; Said fastener 9 comprises nut 24, screw rod 18, abnormity nut 23, and abnormity nut 23 is provided with to what extended both sides and helps to shoulder heavy thing 22, vertically is provided with groove button 21 upwards; Form cannelure 20 between upper bolt 6 and the valve seat 12, the U type notch 19 that is arranged on the upper bolt 6 links to each other with cannelure 20, screw rod 18 pass U type notch 19 and be connected upper bolt 6 and valve seat 12 between; Nut 24 is fixed on the top of screw rod 18, and abnormity nut 23 is fixed on the bottom of screw rod 18, helps to shoulder heavy thing 22 to be connected between the upper bolt 6 and valve seat 12 of cannelure 20 both sides; Help to shoulder heavy thing 22 play upper bolt 6 and valve seat 12 fixation; Groove button 21 is buckled in the cannelure 20, and groove button 21 mainly plays the role of positioning, and can prevent that bolt 18 is loosening.
In order when bump takes place, to play the effect of protection upper bolt 6 better, screw rod 18 is provided with the groove 25 that contracts.
Screw mandrel 16 separates with action bars 5 for ease; And prevent that screw mandrel 16 and action bars 5 from squinting all around, and being fixed with guide pin bushing support 10 on the described valve seat 12, guide pin bushing support 10 centers are provided with rotating guide pin bushing 8; Guide pin bushing 8 axial location are on guide pin bushing support 10; Spool 13 cooperates with valve seat 12 and is connected with screw mandrel 16, and screw mandrel 16 is connected on the guide pin bushing 8 through threaded engagement, and action bars 5 bottoms flexibly connect through concavo-convex joint 7 and guide pin bushing 8; For guarantee spool 13 and screw mandrel about in the of 16 straight line move, described valve seat 12 is provided with guide groove 11, spool 13 is provided with prerotation vane 17, prerotation vane 17 is arranged in the guide groove 11.Install for ease, described valve seat 12 is fixed with Connection Block 14.Draining for ease is provided with the elbow 15 that leaks on valve seat 12.
When the utility model normally used, rotating operation bar 5, action bars 5 were through 8 rotations of concavo-convex joint 7 drive guide pin bushings, and straight line moved about screw mandrel 16 was done under guide pin bushing 8 rotations drive, and opened or closed thereby drive spool 13.When upper bolt 6 receives the external force collision, several kinds of phenomenons below fastener 9 can produce: the one, abnormity nut 23 produces distortion, and screw rod 18 and abnormity nut 23 are deviate from from U type notch 19; The 2nd, groove 25 places of contracting of screw rod 18 are stressed weak links, break after screw rod 18 is clashed into; The 3rd, nut 24 receives with abnormity nut 23 and clashes into the sliding dental phenomenon of back generation; Cause upper bolt 6 to separate with valve seat 12; Action bars 5 separates with guide pin bushing 8 automatically; The valve state that keeps shut so both can protect upper bolt 6 can not damage, and can guarantee that again tap water can not leak simultaneously; 6 of upper bolts need to change nut 24, screw rod 18 and abnormity nut 23 can be continued to use, and does not influence the application life of fire plug.
