Abstract
The utility model provides a fire control valve of marine fire hydrant, this fire control valve be including valve body, valve disc, valve rod, valve gap, valve wheel, bolt, rubber circle, the valve body is direct or right angle type fire control valve body, the valve disc is fixed in valve rod one end, and the other end passes the valve gap and is fixed with the valve wheel, valve disc and valve body are the taper surface contact, and open on the taper surface and have the dovetail groove, the rubber circle is the trapezoid cross section, inlays in the dovetail groove of valve disc taper surface, the valve gap passes through the bolt fastening on the valve body. The utility model discloses an effect is that this valve is not only met heat energy and is enough protected the rubber circle, satisfies the requirement of newly standardizing SOLAS, and conical contact has increased the sealing contact area in addition, has reduced the destruction of debris to sealed face, reaches to prevent seepage technical requirement.
Description
Technical field
The utility model relates to ship's fire fighting system, particularly the fire valve of fire hydrant peculiar to vessel.
Background technique
Along with the increase of the tonnage of ship, make its system and power day by day complicated, bring countless potential fire point of ignition thus.Fire hydrant is as suppression and put out rapidly by fire at the most direct fire-fighting instrument in burning things which may cause a fire disaster place, and in daily use, often occurs Seepage, cause the main cause of this phenomenon be fire valve repeatedly opening and closing make caused by its sealing surface destroys.
According to GB GB/T2032-1993 flange fire hydrant peculiar to vessel, the sealing surface wherein in regulation valve has two kinds of selections: metal and nonmetal.Metal sealing requires that material is identical with valve body and valve disc material; Nonmetal sealing refers to that surface of contact place increases General Purpose Rubber plate.And SOLAS2009 specification explicitly calls for: heat is easy to the material lost efficacy, unless it has sufficient protection, must not be used for fire main pipe and fire hydrant.Applying thus along with SOLAS new criteria, adopts metal sealing usually for hydrant valve inner sealing surface peculiar to vessel.And planar metal sealing adopted in the market, due to fire hydrant opening and closing repeatedly, cause foreign material to sealing surface wear or scuffing, and factors such as colliding with is there is in transport or handling process, the distortion of fire hydrant sealing surface may be caused, cause the valve disc of fire valve and valve seal not good and occur Seepage.
Summary of the invention
For solving the problems of the technologies described above, the utility model proposes a kind of fire valve of fire hydrant peculiar to vessel, this valve not only increases sealing contact surface and amasss, and significantly reduces the destruction of foreign material to sealing surface.
For achieving the above object, the technological scheme that the utility model adopts is to provide a kind of fire valve of fire hydrant, this fire valve includes valve body, valve disc, valve rod, valve gap, valve wheel, wherein: described valve body is straight-through or rectangular shape fire-control valve, described valve disc is fixed on valve rod one end, the valve rod the other end is fixed with valve wheel through valve gap, described valve disc contacts with tapered of valve body, and conical surface has dovetail groove, described rubber ring is trapezoid cross section, be embedded in the dovetail groove of valve disc conical surface, described valve gap is bolted on valve body.
The beneficial effects of the utility model be this valve not only heat can protect rubber ring, meet the requirement of new criteria SOLAS, and taper-face contact increases sealing contact surface and amasss, and reduces the destruction of foreign material to sealing surface, reaches and prevent seepage technical requirements.
Accompanying drawing explanation
Fig. 1 is through-type structural representation of the present utility model;
Fig. 2 is rectangular shape structural representation of the present utility model;
Fig. 3 is the amplification assumption diagram of valve body in Fig. 1.
In figure: 1, valve body 2, valve disc 3, valve rod 4, valve gap 5, valve wheel 6, bolt 7, rubber ring
Embodiment
By reference to the accompanying drawings the structure of the fire valve of fire hydrant peculiar to vessel of the present utility model is illustrated.
The design philosophy of the fire valve of fire hydrant peculiar to vessel of the present utility model is curved surface pattern by changing the valve disc conical surface, increases sealing contact surface and amass, reduce the destruction of foreign material to sealing surface, reach and prevent seepage technical requirements.
As Fig. 1, shown in Fig. 2 and Fig. 3, the fire valve structure of fire hydrant peculiar to vessel of the present utility model is, this fire valve includes valve body 1, valve disc 2, valve rod 3, valve gap 4, valve wheel 5, bolt 6, rubber ring 7, described valve body 1 is straight-through or rectangular shape fire-control valve, described valve disc 2 is fixed on valve rod 3 one end, valve rod 3 the other end is fixed with valve wheel 5 through valve gap 4, described valve disc 2 contacts with tapered of valve body 1, and conical surface has dovetail groove, described rubber ring 7 is in trapezoid cross section, be embedded in the dovetail groove of valve disc 2 conical surface, described valve gap 4 is fixed on valve body 1 by bolt 6.
The fire valve structure of fire hydrant peculiar to vessel of the present utility model is achieved in that the valve body 1 of this fire valve is for straight-through or rectangular shape fire valve, valve disc 2 is fixed in valve rod 3 one end, the other end is through valve gap 4 standing valve wheel 5, valve disc 2 contacts with tapered of valve body 1, and conical surface has dovetail groove, rubber ring 7 is in trapezoid cross section, and be embedded in the dovetail groove of valve disc 2 conical surface, described valve gap 4 is fixed on valve body 1 by bolt 6.
In the process of the fire valve of assembling fire hydrant peculiar to vessel, be first embedded in by rubber ring 7 in the dovetail groove of valve disc 2, then valve disc 2 is fixed on valve rod 3 one end, valve gap 4, through valve gap 4 standing valve wheel 5, is fixedly mounted on valve body 1 by bolt 6 by the other end.During application, valve disc 2 is driven to move up and down by rotary valve wheel 5.When closing the fire valve of fire hydrant peculiar to vessel, valve disc 2 and the tapered sealing surface of valve body 1, now sealing surface is contacted with metal sealing by both sides metal, intermediate rubber circle contacts with metal sealing and form.The tapered contact of sealing surface, increases area of contact, and significantly reduces the destruction of foreign material to sealing surface.During heat, both sides metal sealing all plays the effect of protection rubber ring 7 simultaneously, meets SOLAS code requirement, and can be a large amount of put in the application of ship's fire fighting bolt, prevents rubber ring to be out of shape, improve Safety performance, avoid potential potential safety hazard.
