Description
Technical field
The utility model relates to a kind of fire-fighting equipment, particularly a kind of quick unlatching fire plug.
Background technology
Traditional above ground hydrant is a kind of outdoor ground fire fighting supply facility.For supplying water or directly connect and put out a fire with water band, hydraulic giant to fire fighting truck, it is the special facilities of outdoor indispensable fire fighting supply.Basset in its top, sign obviously, easy to use.Post fire hydrant is the fire-fighting equipment of a kind of city indispensability, and extensively install in the densely populated areas such as each factories and miness, warehouse, harbour, goods yard, high buildings and large mansions, public place.Traditional fire hydrant structure by valve body, valve rod, certainly let out the component such as valve and interface pedestal and form.The unlatching of fire plug, by rotary screw type valve rod, makes valve plate open or close, and sometimes needs to rotate multi-turn, and operation slowly, is opened and will be affected fire extinguishing effect slowly, closes slowly and will cause waste water resource.In addition, because post fire hydrant overground part is easily clashed into and ruptures, maintenance difficult not only, and can cause great lot of water resources waste.
Chinese patent 200820028378.2 discloses a kind of self-closing anti-collision hydrant, can effectively reduce the probability that fire plug is damaged, and once break, valve plate moves upward under the effect of hydraulic pressure, its conical surface coordinates with inclined-plane in key to be realized self-closingly, effectively prevents the loss of fire protection pipeline water.The problem of its existence is, valve rod is monolithic, once fire plug is knocked, valve rod can flexural deformation, thereby can cause the poorly sealed phenomenon of valve plate to occur, and this self-closing anti-collision hydrant not have to solve the problem of unlatching fast yet.
Utility model content
In order to address the above problem, the utility model provides a kind of quick unlatching fire plug, and this fire plug can be realized quick unlatching, also have simultaneously voltage-regulation voltage-stabilization, antifreeze, sever rear self-closing function.
The utility model solves the technical scheme that its technical problem adopts: a kind of quick unlatching fire plug, comprise body, valve body and base, in described valve body, be provided with the valve plate being sealed and matched with MEDIA FLOW port end face, what be connected with valve plate can stretch out and be connected in the rotational structure on body by axially movable valve rod in body, it is characterized in that, between body and valve body, by securing member, be connected with matrix, described rotational structure comprises, be arranged in valve stem tip groove and partly protrude from the ball outside groove, described cam is arranged in the cam chamber of body upper end and is compressed by cover plate, the through hole of cam end axle on cover plate stretches out, the work plane of described cam keeps in touch with ball all the time.
Described valve rod comprises upper valve rod, adapter and lower valve rod, in the top groove of upper valve rod, accommodating ball contacts with the work plane of cam, lower end is inserted in adapter upper port also spacing by crossette, take in lower port and be plugged with transition embolism, described transition embolism is provided with axial hole, the top of lower valve rod is provided with spring upper limit cover, the columnar part of one spherical connector is plugged in the axial hole of transition embolism, spherical part is placed in lower valve rod top and upper limit overlaps in the groove forming, and described body and matrix binding site are in the middle part of taking over; Described valve body middle part is provided with a plurality of connecting rods that arrange radially that support lower limit cover, and spring housing is placed on lower valve rod and between upper limit cover and lower limit cover.
Described valve plate comprises large valve plate assembly and little valve plate assembly, described large valve plate assembly can axially movably be placed on lower valve rod, the large valve plate upper sealing ring part of large valve plate assembly matches with the sealing shroud end face of valve body media communication port end face setting, the another side relative with large valve plate upper sealing ring part is provided with large valve plate lower seal ring, on large valve plate assembly, is provided with some axially extending bores; Little valve plate assembly fixing seal is nested with on lower valve rod, is provided with large valve plate lower seal ring and coordinates little valve plate sealing ring part on a side of little valve plate assembly, in the bottom of lower valve rod, is provided with locking nut.
On valve body, be also provided with one from letting out valve, the described valve of certainly letting out is communicated with the cavity and the external world in valve body.
The beneficial effects of the utility model are:
1, open rapidly: the utility model has adopted the cam type rising-falling stem structure that is different from existing common bolt, only makes spanner rotating cam end axle can close completely or open for 2/3 week, has avoided the various adverse effects of slowly bringing because of opening speed.
2, crashproof self-closing: the utility model adopts malleation to close mode, as matrix severed rear valve plate can be under spring and pipe network water pressure double action self-closed, sealing, does not affect the normal use of same other hydrant of pipeline, and can realize reparation with pressure immediately.Particularly valve rod is divided into upper and lower two parts, and the setting of spherical connector, after upper body matrix is severed, the impact that valve body and its underpart are subject to is minimum, thereby has guaranteed the reliability of self-closed.
3, voltage-regulation voltage-stabilization: the utility model has adopted large valve plate assembly and little valve plate assembly, at the unlatching initial stage, little valve plate assembly moves down, large valve plate assembly and little valve plate assembly are separately, the sealing shroud end face seal that now large valve plate assembly still arranges with valve body media communication port end face under pipe network water pressure effect contacts, the axially extending bore of current on large valve plate assembly enters valve body, plays throttling action; And after large valve plate assembly upper and lower sides differential water pressures diminishes, the sealing shroud end face of large valve plate assembly and the setting of valve body media communication port end face disengages, medium (water) flow strengthens, and therefore according to the pressure of water supply network and fire hose bearing capacity, can carry out voltage-regulation voltage-stabilization to flowing water.
4, owing to being provided with from letting out valve, hydrant can automatically get rid of fast in off position time in the chamber in more than water, the equipment that prevents is freezing.
This product can be widely used in the enterprise and institution of municipal engineering, all trades and professions.Particularly be applicable to that oil, chemical industry, grain store and timber processing and light textile, port and pier, airport, storage reservoir area etc. all types fire prevention unit, more can be relieved for north cold area.
