Description
Technical field
The utility model relates to a kind of modulating valve, specifically a kind of small-bore single-seat regulating valve of sleeve.
Background technique
In automation control system, modulating valve, as the terminal actuating device in automatic regulating system, according to the command signal of control system, is regulated spool stroke by the actuator supporting with it, thus reaches the object of adjust flux.Conventional single-seat adjusting valve structure is made up of valve body, valve seat, spool, valve gap, valve rod, filling body, fastening piece and Sealing.When actuator accept control signal carry out upper and lower straight-line displacement action time, spool be positioned at below, modulating valve is closed condition; Spool is positioned at top, and modulating valve is opening state.If but when High Pressure Difference easily there is flash distillation and cavitation phenomenon in liquid.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of small-bore single-seat regulating valve of sleeve that can prevent liquid generation flash distillation and cavitation.
The technical solution of the utility model is:
A kind of small-bore single-seat regulating valve of sleeve, comprise valve body, valve gap, valve seat, spool, valve rod, described valve body is provided with fluid inlet, fluid output, described fluid inlet and fluid output are all curved channel, the inner connectivity part of described fluid inlet and fluid output is provided with valve seat, it is characterized in that, described valve body upper end is fixedly connected with valve gap, valve rod is provided with in described valve body and valve gap, described valve rod lower end is connected with the spool that can block valve seat, described spool is fixedly connected on the lower end of valve rod, the outside of described spool is provided with sleeve, described sleeve is arranged on valve seat.
Described valve rod and valve gap upper wall joint are provided with balance spring, and described balance spring is provided with filler, and described filler is provided with Gland.
Between described valve body and valve gap, joint is provided with the first seal ring, and between shown valve body and valve seat, joint is provided with the second seal ring.
The beneficial effects of the utility model are:
Small-bore single-seat regulating valve of sleeve of the present utility model is applicable to the High Pressure Difference occasion of fluid pressure differential more than 3MPa, the valve cage arranged can prevent liquid generation flash distillation and cavitation, fluid passage is that S is streamlined, has that droop loss is little, flow is large, adjustable extent is wide, Flow characteristics precision advantages of higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
