Description
Technical field
This utility model relates to a kind of valve, particularly to a kind of fire valve.
Background technology
Fire valve is a kind of important accessory controlled on industry, building pipeline, and fire valve is due to close during opening and closing
Between front cover, frictional force is little, relatively durable, and Lift is little, easy to manufacture, easy to maintenance, is applicable not only to mesolow, and
And it is applicable to high pressure.Its Guan Bi principle is dependent on valve rod pressure, makes sealing surface of seat fit tightly with valve body sealing surface, stops and be situated between
Mass flow is led to.The sealing surface of seat of existing fire valve and valve clack sealing surface are generally conical seal (contact) face or the circular arc that pair of matched is closed
Face, both constitute line contact sealing, though the sealing means good sealing effect of this structure, this sealing surface quality of fit is wanted
Asking high, difficulty of processing is big, manufactures complexity, and after longtime running, sealing surface easily weares and teares or damages, close between flap and valve seat
Sealing property reduces, and leakage phenomenon easily occurs, affects sealing reliability, and the sealing surface after wearing and tearing or damaging is difficult to repair, and increases
Maintenance cost, is affected the service life of product.
Summary of the invention
This utility model is for the deficiencies in the prior art, it is provided that one is easy to manufacture, easy to process, sealing reliability is good,
Low cost, the wear-resisting right angle fire valve of length in service life.
This utility model is achieved through the following technical solutions technical goal.
Wear-resisting right angle fire valve, including valve body, valve disc, valve gap, valve rod, handwheel, bonnet；It is provided with into water in described valve body
Mouth, outlet and connection water inlet, the connector of outlet；Described water inlet is the most at a right angle with outlet, connector with enter
The mouth of a river is coaxially disposed, and is provided with sealing surface on the top of connector in valve body, and the upper plane of valve body is provided with seam；Described valve gap passes through
Studs and nut I are fixedly connected on the upper plane of valve body, and the boss of its bottom surface coordinates with the seam of plane on valve body, valve gap
Central lower is provided with female thread, and top is provided with annular seal space, is provided with airtight and watertight padding around stem exterior surface in annular seal space；Described bonnet
It is arranged on the top of valve gap, between bonnet and airtight and watertight padding, is provided with gland；Described valve rod is vertically arranged between body cavity, outside middle part
Surface is provided with the external screw thread engaged with bonnet lower female thread, and upper end sequentially passes through valve gap, bonnet is fixedly connected with the hand wheel, lower end
It is flexibly connected with valve disc；It thes improvement is that: the baseplane of described valve disc is provided with annular groove, sets in described annular groove
There is ring packing sheet；Described ring packing sheet is locked by pressing plate and nut II, the end face of ring packing sheet and connector top
Sealing surface fit tightly and form sealing.
In said structure, described valve gap outer surface of upper is provided with screw thread, and bonnet is threaded in valve gap top, screws valve
Cap, bonnet extruding gland, gland crush seal filler.
In said structure, described valve body inner sealing surface is provided with wear-resistant coating.
This utility model compared with prior art, has the positive effect that:
1, the ring packing sheet end face on this utility model valve disc fits tightly formation with flat seal face on connector
Plane sealing structure good airproof performance, between sealing surface, frictional force is little, and service life is long, and simple in construction is easy to process, anufacturability
Good, it is simple to maintenance.
2, directly the internal and external threads structure being bonded with each other is set on valve gap and valve rod, simplifies the structure of fire valve, fall
Low production cost；Valve gap outer surface of upper is provided with screw thread, and bonnet screws in valve upper part of the cover screw thread, and airtight and watertight padding is by bonnet
Screwing extruding gland to be pressed in the annular seal space of valve gap, this structure makes the overall dimensions of fire valve little, and airtight and watertight padding is at valve
The effect lower stress of cap is uniform, improves sealing property of the present utility model further.
3, on the sealing surface of the upper surface of connector, it is provided with wear-resistant coating in valve body so that this utility model has preferably
Wearability, corrosion resistance and shock resistance, notable extend this utility model service life.
