Description
Technical field
The invention belongs to the valve of media flow in the controlling plumbing fixtures of universal machine field.
Background technique
Conventional General valve has following several in the existing industrial pipeline:
(1) (Fig. 1 a) for gate valve
Main feature is: drive valve rod by handwheel and connect flashboard, make the valve of elevating movement along the sealing surface of valve seat.Sealing is to rely on the angle of wedge-type flashboard and ring-like valve seat to coincide to realize.This valve arrangement is simple, and cost performance of product is moderate, uses very general.Because valve seat is built-up welding or is embedded in the valve body, and part can not be general, maintenance needs specialized apparatus, and personnel will have certain technical guarantee.
(2) stop valve (Fig. 1 b)
Main feature is: working principle is that handwheel drives valve rod, makes a kind of valve of elevating movement along the sealing surface axis of valve seat.Sealing generally is to rely on valve seat and fitting tightly of flap to realize.Because this valve arrangement is simple, cost is lower mutually, keep in repair more conveniently, so obtains the utilization of wide model.Shortcoming is that axial force is bigger when closing, and the moment of operation often is subjected to the using effect that influences of manpower size, and secondly the fluid resistance of this valve is bigger, and energy-saving effect is not ideal.
(3) ball valve (Fig. 1 c)
Open-shut device (spheroid) drives valve rod by handle, wind valve perpendicular to the axis rotation of path, compress at pretightening force or fluid pressure action lower valve base and spheroid, its sealing effect depend on valve seat in the size of hydrodynamic pressure or pretightening force, can compensate the degree of spheroid out of roundness and surface microscopic injustice.In addition, after the ball valve assembling and setting was good, the pretightening force on the sealing surface was just fixing, but after ball valve uses a period of time, because the wearing and tearing of valve seat, and the plasticity residual deformation, the valve seat that fits tightly and spheroid will be gradually loose, seal pressure also will reduce gradually and seepage take place.Though this is that the seat material sealability is superior with plastics, shortcoming is that this valve can not be applied in the high temperature occasion.
Summary of the invention
In order to overcome the deficiency of existing all class valve technology, the invention provides a kind of plane rotation valve flap stop valve, the moment of its operation can not be subjected to the influence of manpower size, can fit tightly with valve seat and can be applied on the device of high temperature occasion at initial tension of spring and fluid pressure action lower Disc.
To achieve the above object, solution of the present invention is: lever bearing pin one, bearing pin two, bearing pin three respectively with arm, movable rod, valve rod interconnects, handwheel drives the Stem Mut rotation, Stem Mut drives valve rod and moves up and down, valve rod connects connecting rod by screw, positioning screwn connects flap, Stem Mut places the endoporus of gland, gland screw thread and valve body screw thread screw, the sealing of valve rod is by the filler Gland, swing bolt compresses, accessory body screw thread and valve body screw, positioning shaft 1 places accessory body respectively with positioning shaft 2, pad, flap, valve seat, in the endoporus of projection, butterfly spring is installed on the positioning shaft 2, the position that one side and accessory body protrude is by touching, and another side contacts with pad.
Adopt the effect that is produced behind the such scheme as follows:
1, good seal performance: because the material application structure ceramic making of flap and valve seat or use the hard facing alloy material, sealing means adopts planar slide to rotate form, utilizes the interior hydrodynamic pressure of spring pretension and pipeline can reach sealing.
2, operational torque is little: with industrial structure pottery, hard facing alloy manufactured good very high hardness is arranged, existing ripe technology can be made bright and clean sealing plane, is that the screw pair kind of drive or wrench operated are all easily convenient than conventional products.
3, long service life: utilize structural ceramics to have very high resistance to compression, resistance to chemical attack, high temperature resistant outstanding performance and make sealing pair, its high hardness can stand washing away of high-velocity fluid, owing to no matter open or close in the closed procedure at flap, two sealing surfaces of its valve seat and flap remain the state of fitting tightly, and accumulate impurity on sealing surface so hard sharp edge can be wiped.
4, save metallic material: for the change of sealing material and seal form, make the valve mechanism compactness, overall weight descends to some extent, low cost product.
