The quick opening hydrant comprises a body, a valve body and a base, a valve plate in seal fit with a medium circulation port end face is arranged in the valve body, and a valve stem connected with the valve plate and capable of moving axially extends out of the body and is connected with a rotating structure arranged on the body. The quick opening hydrant is characterized in that a base body is connected between the body and the valve body through fasteners, the rotating structure comprises a ball which is arranged in a groove at the top end of the valve stem and partially protrudes over the groove, a cam is arranged in a cam chamber arranged at the upper end of the body and tightly pressed by a cover plate, a cam end shaft extends from a through hole in the cover plate, and a working surface of the cam keeps in contact with the ball constantly. The hydrant is capable of achieving quick opening and has functions of pressure regulating and pressure stabilizing, antifreezing and self closing after breakage.
Description
Technical field
The present invention relates to a kind of fire-fighting equipment, particularly a kind of quick unlatching fire plug.
Background technology
Traditional aboveground hydrant is a kind of outdoor ground fire fighting supply facility.Being used for to fire fighting truck water supply or directly connecting with water band, hydraulic giant putting out a fire, is the special facilities of outdoor indispensable fire fighting supply.Basset in its top, sign obviously, and is 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 mines, 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 makes valve plate open or close by the rotary screw type valve rod, sometimes needs to rotate multi-turn, and operation is slow, and opening will affect the fire extinguishing effect slowly, closes slowly to cause waste water resource.In addition, owing to easily being clashed into, the post fire hydrant overground part ruptures, maintenance difficult not only, and can cause the 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, in a single day and when breaking, valve plate moves upward under the effect of hydraulic pressure, inclined-plane in its conical surface and the key cooperates realization self-closing, effectively prevents the loss of fire protection pipeline water.The problem of its existence is, valve rod is monolithic, in case 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 fast problem of unlatching yet.
Summary of the invention
In order to address the above problem, the invention provides a kind of quick unlatching fire plug, this fire plug can be realized quick unlatching, also have simultaneously voltage-regulation voltage-stabilization, antifreeze, sever rear self-closing function.
The technical solution adopted for the present invention to solve the technical problems is: a kind of quick unlatching fire plug, comprise body, valve body and base, in described valve body, be provided with the valve plate that is sealed and matched with MEDIA FLOW port end face, what link to each other with valve plate can axially movable valve rod stretches out in body and is connected on the rotational structure on the body, it is characterized in that, between body and valve body, be connected with matrix by securing member, described rotational structure comprises, be arranged at and also partly protrude from the outer ball of groove in the valve stem tip groove, described cam is arranged in the cam chamber of body upper end and by cover plate and compresses, the through hole of cam end axle on cover plate stretches out, and 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, accommodating ball contacts with the work plane of cam in the top groove of upper valve rod, the lower end is inserted in the adapter upper port also spacing by crossette, take in the lower port and be plugged with the 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 the lower valve rod top and upper limit overlaps in the groove that consists of, 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 the lower limit cover, and spring housing places on the 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 be placed on the lower valve rod with moving axially, the large valve plate upper sealing ring spare of large valve plate assembly matches with the sealing shroud end face of valve body media communication port end face setting, the in addition side relative with large valve plate upper sealing ring spare is provided with large valve plate lower seal ring, is provided with some axially extending bores at large valve plate assembly; Little valve plate assembly fixing seal is nested with on lower valve rod, is provided with in a side of little valve plate assembly with large valve plate lower seal ring to cooperate little valve plate sealing ring spare, is provided with locking nut in the bottom of lower valve rod.
On valve body, also be provided with one from letting out valve, described from letting out the interior cavity of valve connection valve body with extraneous.
The invention has the beneficial effects as follows:
1, open rapidly: the present invention has adopted the cam type rising-falling stem structure that is different from existing common bolt, and spanner rotating cam end 2/3 week of axle can be closed or open fully, has avoided the various adverse effects of slowly bringing because of opening speed.
2, crashproof self-closing: the present invention 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 with other hydrant of pipeline immediately, and can realize reparation with pressure.Particularly valve rod is divided into up and down two parts, and the setting of spherical connector, so that after the upper body matrix severed, the impact that valve body and its underpart are subject to was minimum, thereby has guaranteed the reliability of self-closed.
3, voltage-regulation voltage-stabilization: the present invention 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, this moment, large valve plate assembly still contacted with the sealing shroud end face seal that valve body media communication port end face arranges under the pipe network water pressure effect, 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 pressure and the fire hose bearing capacity of water supply network, can carry out voltage-regulation voltage-stabilization to flowing water.
4, owing to being provided with from letting out valve, water more than hydrant can be got rid of in off position the time automatically fast in the chamber in, 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 be used for north cold area.
