Abstract
The utility model discloses a kind of high-pressure cage adjusting valve, comprise valve body, valve gap, valve rod, mangetic core assembly, it is characterized in that: described valve seat is placed on the valve seat pad in the valve seat orifice of valve body, described valve body upper end is fixedly connected with the valve gap that has central passage, between described valve body and valve gap, be provided with valve cage, described valve cage is sleeved on the outside of spool and is placed on the upper-end surface of valve seat, stretch out outside valve gap through central passage the upper end of described valve rod, described valve rod lower end is connected with mangetic core assembly, in described mangetic core assembly, be embedded with elasticity C type ring, in mangetic core assembly groove, embed successively from inside to outside expanding ring, guide ring, the joint of described valve cage and valve body is provided with seal ring.High-pressure cage adjusting valve of the present utility model effectively raises leakage grade, and it is streamlined that fluid passage is S, has the advantages such as droop loss is little, dynamic stability is high, noise is low, cavitation corrosion is little, has increased the working life of valve.
Description
Technical field
The utility model relates to a kind of modulating valve, specifically a kind of high-pressure cage adjusting valve.
Background technique
Tradition cage valve has plenty of two hard seal points, be that valve cage, valve seat are a hard sealing, on spool, sealing surface and valve cage upper valve base seal firmly for another, if machining accuracy not or material selection not at that time, two seal points can not reach sealing effect simultaneously, and its leakage rate can increase so.Also having one is linear sealing, it is the seal form that spool, valve seat adopt different amount, friction sealed by seal ring and valve cage in whole stroke, although can lean on the continuous supply of the elasticity of support ring, but repeatedly repetitive operation friction also can cause the damage of seal ring, do not play sealing, affect the working life of valve.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of high-pressure cage adjusting valve.
The technical solution of the utility model is:
A kind of cage type regulating valve, comprise valve body, valve gap, valve rod, mangetic core assembly, it is characterized in that: described valve seat is placed on the valve seat pad in the valve seat orifice of valve body, described valve body upper end is fixedly connected with the valve gap that has central passage, between described valve body and valve gap, be provided with valve cage, described valve cage is sleeved on the outside of spool and is placed on the upper-end surface of valve seat, stretch out outside valve gap through central passage the upper end of described valve rod, described valve rod lower end is connected with mangetic core assembly, in described mangetic core assembly, be embedded with elasticity C type ring, in mangetic core assembly groove, embed successively from inside to outside expanding ring, guide ring, the joint of described valve cage and valve body is provided with seal ring.
Described valve rod and valve gap upper wall joint are provided with balance spring, and described balance spring below is provided with pad, and described balance spring is provided with filler, and described filler is provided with Gland.
Between described valve body and valve gap, be provided with the first stainless steel serrated seal circle, between described valve seat and valve body, be provided with the second stainless steel serrated seal circle.
The beneficial effects of the utility model are:
High-pressure cage adjusting valve of the present utility model effectively raises leakage grade, and it is streamlined that fluid passage is S, has the advantages such as droop loss is little, dynamic stability is high, noise is low, cavitation corrosion is little, has increased the working life of valve.
