Description
Technical field
The utility model is related to oil production equipment fields, and in particular to a kind of no flange liquid-operated flat valve.
Background technology
In domestic and international existing petrochemical equipment, flap type is all single type of drive；I.e.：Or handwheel driving or
Hydraulic-driven or motor driving or air pressure driving.In addition to handwheel drives, other type of drive are required to an auxiliary system
System is, it is necessary to there is precondition；If auxiliary system goes wrong or precondition missing, the pipe of entire flap type control will be made
Road or equipment just can not be run.
For some important pipelines or equipment, it can not run and mean that heavy economic losses or security incident.It is existing
The solution for ensuring operation is typically " bivalve configuration "：I.e. near the valve automatically controlled, a hand control valve of connecting；
If complicated pipeline or equipment, then using more autocontrol valves, this not only adds the volumes and again of pipeline or equipment
Amount, and also increase the cost of investment of user.
Utility model content
The technical problems to be solved in the utility model be overcome the deficiencies of the prior art and provide a kind of no flange surge it is flat
Plate valve by changing the structure of valve seat and valve plate, improves the reliability of flap type, so as to reduce well-repairing work amount, mitigates worker
Labor intensity, reduce operation cost.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of no flange liquid-operated flat valve, including valve
Body, driving hydraulic cylinder component, valve deck and valve board assembly；The valve deck is fixed on valve body, and the driving hydraulic cylinder component is set
On valve deck, the upper end of the valve board assembly is connected with the lower part of driving hydraulic cylinder component, and the valve board assembly is arranged in valve body
Portion；The valve board assembly includes valve seat, valve plate and valve rod, and the valve plate is fastened in valve seat, and the valve rod is fixed on valve plate；
The middle part of the valve seat is convex sphere, which is equipped with valve plate guide groove.
Further improved as the utility model, the valve plate both sides are arranged with wear rib, the width of the wear rib
With the consistency of thickness of convex sphere.
Further improved as the utility model, the valve seat includes symmetrical two and half valve seat, half valve seat
Including seat is convex and seat bar, seat bar fixes present convex rear portion.
Further improved as the utility model, the seat bar is hollow tubular.
Further improved as the utility model, the convex seat is hollow arcuation body, and the convex both sides of this are arranged with limit
Position block.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
By changing the structure of valve seat and valve plate, the reliability of flap type is improved, so as to reduce well-repairing work amount, mitigates work
The labor intensity of people, cuts operating costs.

The opening and closing of existing flap type.
Valve deck 3 is fixed on valve body 2, and driving hydraulic cylinder component 1 is arranged on valve deck 3, the upper end of the valve board assembly and drive
The lower part connection of hydrodynamic pressure cylinder component 1；Valve board assembly is arranged on inside valve body 2；Valve board assembly includes valve seat 5, valve plate 6 and valve rod
7；Valve plate 6 is fastened in valve seat 5, and valve rod 7 is fixed on valve plate 6；The middle part of valve seat 5 is convex sphere, which is equipped with valve
Plate guide groove.
Convex sphere is split type, individually can dismantle and assemble, valve plate guide groove is located at two convex ball centres.
6 both sides of valve plate are arranged with wear rib, and the consistency of thickness of the width of the wear rib and convex sphere extends valve plate 6
Service life.
Valve seat 5 includes symmetrical two and half valve seat, which includes seat convex 8 and seat bar 7, and seat bar 7 is fixed present
Convex 8 rear portion.Seat convex 8 and seat bar 7 are hollow structure.
Seat convex 8 is hollow arcuation body, and the convex both sides of this are arranged with limited block 9, ensure the stabilization of 6 uplink and downlink of valve plate
Row.
Valve plate 6 moves in valve plate guide groove always.
It the above is only the concrete application example of the utility model, do not form any limit to the scope of protection of the utility model
System.All technical solutions formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
