Abstract
An assembling pressure head for L-shaped gate valve plate sealing rings is provided with a rectangular hilt. A horizontal press rolling shaft is disposed on the upper end surface of the hilt, an axis of the horizontal press rolling shaft is parallel to the length direction of the hilt, a roller bearing is sleeved on the horizontal press rolling shaft, and the outer diameter of the roller bearing is larger than the width and the thickness of the hilt. An L-shaped valve plate sealing ring can be embedded onto a valve plate sealing seat in a rolling pressed manner by the assembling pressure head, the labor intensity for assembling the valve plate sealing ring is low, and the size precision of the valve plate sealing ring after the valve plate sealing ring is mounted is high.
Description
Technical field
The utility model relates to a kind of gate valve assembling frock, the frock of using when particularly a kind of gate valve valve plate sealing ring assembles.
Background technology
Gate valve has cylinder valve, two ends along valve axis have respectively into, outlet, have in the valve body and stretch out the outer and valve shaft vertical of valve body with valve axis, on the valve shaft in the valve body valve plate is arranged, advancing of valve interior wall, the exit has the annular valve seal receptacle respectively, be embedded with the annular valve sealing ring on the valve seal seat, the both sides of valve plate have annular valve plate seal receptacle respectively, be embedded with the annular valve plate sealing ring that matches with the valve seal ring on the valve plate seal receptacle, mostly the valve body of gate valve and valve plate generally are that cylinder iron material is made, and valve seal ring and valve plate sealing ring can be to make with materials such as copper or stainless steels.Valve seal ring and valve plate sealing ring are that the cross section is the annular seal ring of T shape, the T V-shaped ring has at the annular seal face of T V-shaped ring one side with at the cylindrical shape installing handle of T V-shaped ring opposite side, the barrel surface of plane, annular seal face place and cylindrical shape installing handle is perpendicular, and the annular dovetail groove that matches with the cylindrical shape installing handle of T V-shaped ring is arranged on valve seal seat and the valve plate seal receptacle.In the prior art, do not assemble the frock of gate valve valve plate sealing ring, when assembling the valve plate sealing ring of gate valve, the installing handle of T-valve plate sealing ring is placed on the annular dovetail groove notch on the valve plate seal receptacle, the method of beaing by hand embeds installing handle in the dovetail groove, embed the interior installing handle of dovetail groove because of beaing the distortion that can produce with the dovetail groove shape, T-valve plate sealing ring is embedded on the seal receptacle, the outer surface that this T-valve plate seal ring seal ring intersects is many, processing capacity is bigger, the sealing surface that intersects between assembling back T-valve plate sealing ring and the valve seal seat is more, and some sealing surface is not very regular, causes leakage at the sealing ring place easily.It is big that the method for beaing is by hand installed valve plate sealing ring labour intensity, and dimensional accuracy is low after installing.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and when proposing a kind of installation gate valve valve plate sealing ring, labour intensity is little, and dimensional accuracy high L shaped gate valve valve plate sealing ring assembling pressure head in back is installed.
The utility model is realized with the following method.
L shaped gate valve valve plate sealing ring assembling pressure head has the cuboid handle of a knife, and there is the axis horizontal nip drum axle parallel with the length direction of handle of a knife the upper surface of handle of a knife, is with ball bearing on the horizontal nip drum axle, and the external diameter of ball bearing is greater than the width and the thickness of handle of a knife.
The utility model can embed the L shaped valve plate sealing ring of gate valve the valve seal seat of gate valve with the method for roll extrusion.On the annular valve plate seal receptacle of gate valve the toroidal cavity concentric with the annulus of annular seal seat arranged, the trough rim of toroidal cavity is a round table surface shape, and the cone angle of groove limit round table surface is 6 degree ~ 10 degree.L shaped valve plate sealing ring is that the cross section is L shaped annulus, L shaped valve plate sealing ring has the annular seal face in L shaped valve plate sealing ring one side, the inner periphery of annular seal face is connected with round platform tubular installing handle, the axis of plane, annular seal face place and round platform tubular installing handle is perpendicular, and the angle between the round table surface of plane, annular seal face place and round platform tubular installing handle is 85 degree ~ 87 degree.
When making L shaped valve plate sealing ring, can be made into initial L shaped valve plate sealing ring earlier, the plane, annular seal face place of initial L shaped valve plate sealing ring and the barrel surface of cylindrical shape installing handle are perpendicular, during assembling, the cross section that initial L shaped valve plate sealing ring is placed on the annular valve seal receptacle is on the L shaped step, can be embedded in L shaped valve plate sealing ring the interior collar extension place of valve seal seat with the method for roll extrusion with the utility model.
The outer surface that L shaped valve plate sealing ring intersects is less, processing capacity is less, and the outer surface that L shaped valve plate sealing ring intersects is few, and the sealing surface that intersects between assembling L shaped valve plate sealing ring in back and the valve seal seat is less, sealing surface is very regular, is not easy to cause leakage in sealing ring assembling place.
The utility model can be embedded in the roll extrusion of L shaped valve plate sealing ring on the valve seal seat, and the labour intensity of assembling valve plate sealing ring is little, and back dimensional accuracy height is installed.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is that the master of a kind of L shaped gate valve valve plate sealing ring assembling pressure head that proposes according to invention scheme of the present utility model looks schematic diagram;
Fig. 2 is the schematic side view of Fig. 1;
Fig. 3 is the schematic diagram that assembles L shaped gate valve valve plate sealing ring with L shaped gate valve valve plate sealing ring assembling pressure head.
The specific embodiment
Among Fig. 1, Fig. 2, L shaped gate valve valve plate sealing ring assembling pressure head has cuboid handle of a knife 1, there is the axis horizontal nip drum axle 3 parallel with the length direction of handle of a knife the side 2 of handle of a knife, is with ball bearing 4 on the horizontal nip drum axle, and the external diameter r of ball bearing is greater than the thickness a of handle of a knife.
Among Fig. 3, can be assemblied in L shaped gate valve valve plate sealing ring on the gate valve body seal receptacle on the vertical lathe with the utility model.
During assembling, gate valve is fixed on the lathe platform, the utility model 5 is fixed on the knife rest, initial L shaped valve plate sealing ring 6 is placed on the above-mentioned gate valve body seal receptacle 7, the installing handle of initial L shaped valve plate sealing ring is placed on the notch of the toroidal cavity 8 on the above-mentioned annular valve plate seal receptacle, allow the periphery 9 of ball bearing be pressed on the annular seal face 10 of initial L shaped valve plate sealing ring, open lathe and drive the gate valve rotation, driving the utility model walks about along its length, ball bearing is pressed into the installing handle 11 of initial L shaped valve plate sealing ring in the toroidal cavity on the valve plate seal receptacle, because the cone angle of the round table surface on groove limit is 3 degree ~ 5 degree, make the angle between the round table surface of plane, annular seal face place and round platform tubular installing handle in the roll extrusion process, be deformed into 85 degree ~ 87 degree, L shaped valve plate sealing ring is embedded on the valve plate seal receptacle.
