Description
Technical field
The utility model relates to a kind of modulating valve, specifically a kind of venturi angle type control valve.
Background technique
Venturi angle type control valve spool adopts upper guide structure, and valve arrangement is compact, and droop loss is little, and flow is large, and adjustable extent is wide, is applicable to control the fluid containing particle and mud, viscosity or flash distillation fluid.But owing to containing the solid particles such as cinder in medium, and flow velocity is high, pressure reduction large, very easily causes the erosion to valve, wearing and tearing.Especially flow control valve, due to the full-gear that its working state is not generally low flow resistance, therefore the runner inner wall of its pressure control part (comprising the component such as valve head, valve seat) and valve body is very easily owing to damaging containing the erosion of solid medium at a high speed, causes valve invalidation.
Model utility content
The purpose of this utility model there is provided that a kind of structure is simple, stable performance, erosion resistant venturi angle type control valve.
The technical solution of the utility model is:
A kind of venturi angle type control valve, comprise valve body, valve gap, venturi valve seat, spool, valve rod, support, actuator, it is characterized in that: described venturi valve seat is fixedly connected in the cavity of valve body, described valve body upper end is fixedly connected with the valve gap having central passage, described valve gap upper end is fixed with actuator by support, guide sleeve is provided with between described valve body and valve gap, the outer rim upper surface of described guide sleeve and valve gap close contact, valve rod is provided with in described valve body and valve gap, described valve rod lower end is fixed with spool by pin, the other end of described valve rod stretches out outside valve gap through central passage and is connected with the output shaft of actuator, filler is provided with in described valve rod and valve gap Special composition, described filler is provided with Gland.
The targeting part of described spool is extended type.
Flap is provided with in the passage of the water intake of described valve body.
Described actuator is many springs diaphragm actuator.
The beneficial effects of the utility model are:
Venturi angle type control valve of the present utility model adopts extended type due to spool, such that the guiding area of spool is large, shock resistance good, is provided with the shunting wing, effectively can reduces the surge pressure of fluid, add the working life of modulating valve at fluid inlet place.
