Abstract
The utility model discloses an anti-cavitation single-base angle valve. The anti-cavitation single-base angle valve comprises a valve body, a valve seat, a valve core, a valve rod and a valve cover. The valve cover is arranged at the bottom of the valve body and is fixedly connected with the valve body through a screw. The valve core is driven by the valve rod to move up and down so as to open or close a valve door. The anti-cavitation single-base angle valve is characterized in that taper sealing is adopted by the valve core and the valve seat, both the valve core and the valve seat are made of YG8 sintered alloy, a thin YG8 sintered alloy layer is inlayed on the surface of the inner cavity of the valve cover, the valve base is compressed in the valve body through the valve cover, and a stuffing box is arranged on the top of the valve body, and is sealed with the valve rod through teflon filling materials. The anti-cavitation single-base angle valve is used under occasions of medium conveying with large differential pressure, high flow velocity and serious particle washout, and has the advantages of being reasonable in structure, good in sealing effect and long in service life.
Description
Technical field
The utility model relates to a kind of valve that the big flow velocity height of pressure reduction, particle wash away the severe medium transport occasion of erosion that is exclusively used in.
Background technique
At present, wash away at the big flow velocity height of pressure reduction, particle, the medium transport occasion of erosion severity, the working life of valve internals is generally very short, and sealing effect neither be desirable especially.
Summary of the invention
Problem in view of present known technology existence, the technical problems to be solved in the utility model be to provide a kind of for the big flow velocity height of pressure reduction, particle wash away, the medium transport occasion of erosion severity, the anti-cavitation erosion single seat angle valve with rational in infrastructure, good sealing effect, long service life advantage.
The utility model is implemented by the following technical programs:
Anti-cavitation erosion single seat angle valve, comprise valve body, valve seat, spool, valve rod and valve gap, fixedly connected by screw with valve body in the bottom that valve gap is located at valve body, valve rod drives spool and moves up and down opening or closing of realization valve, it is characterized in that: described spool and valve seat adopt conical surface seal, the material of spool and valve seat is the YG8 sintered alloy, and the surface of internal cavity of described valve gap studs with thin layer YG8 sintered alloy.
In the technique scheme, spool and valve seat all adopt YG8 sintered alloy material, has very strong scour resistance, be applicable to the big flow velocity height of pressure reduction, wash away, the medium transport occasion of erosion severity, improve valve working life, in addition, valve gap surface of internal cavity thin layer YG8 sintered alloy arranges the erosion resistibility that has improved valve gap; Also have, described spool and valve seat adopt conical surface seal, the influence that can directly washed away by medium, good sealing effect.
Described valve seat is pressed in the valve body by valve gap.Above-mentioned design makes the rational in infrastructure of valve, and is easy to maintenance.
The top of described valve body arranges stuffing box, adopts tetrafluoro polyethylene filler to seal between stuffing box and the valve rod.Tetrafluoro polyethylene filler can effectively improve sealing and the corrosion resistance of valve.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Embodiment
Describe relevant details and the working principle of the utility model specific embodiment in detail below in conjunction with accompanying drawing:
As shown in the figure, anti-cavitation erosion single seat angle valve of the present utility model, comprise valve body 4, valve seat 6, spool 5, valve rod 1 and valve gap 8, the bottom that valve gap 8 is located at valve body 4 and valve body 4 are fixedlyed connected by screw, valve rod 1 drives spool 5 and moves up and down opening or closing of realization valve, described spool 5 adopts the conical surface 7 sealings with valve seat 6, spool 5 is the YG8 sintered alloy with the material of valve seat 6, the surface of internal cavity of described valve gap 8 studs with thin layer YG8 sintered alloy 9, described valve seat 6 is pressed in the valve body 4 by valve gap 8, the top of described valve body 4 arranges stuffing box 2, adopts tetrafluoro polyethylene filler 3 to seal between stuffing box 2 and the valve rod 1.
