Abstract
The utility model relates to a valve, in particular to a thermal-collected steam stop-rectifying valve. The thermal-collected steam stop-rectifying valve comprises a valve rod, a feeding box, a support frame, a valve body and a hand wheel. The upper end of the valve body is movably connected with the support frame, the hand wheel is connected to the top portion of the valve rod, and the bottom of the valve rod is connected to the inside of the valve body through the feeding box. A throttling cover is arranged inside the valve body, a self-tightened feeding structure is arranged between the feeding box and the valve body, and a feeding press cover is movably connected with the feeding box. The thermal-collected steam stop-rectifying valve has the advantages that the throttling cover is arranged in the valve body, a valve seat and the valve body are protected, the service life of the valve is prolonged, and noise of equipment is lowered at the same time; and when the thermal-collected steam stop-rectifying valve works in a long period in high-temperature steam, long term adjusting and rectifying effects to medium can be achieved, and long term shut-off and stop effects to pipelines can also be achieved.
Description
Technical field
The utility model relates to a kind of valve, and particularly a kind of steam for thermal recovery is by rectifying valve.
Background technique
At present; Industries such as oil, power station, chemical industry need be controlled the situation of steam pipe line; The all various steam regulation valves of many producers, but the problem of its existence is: in the high-temperature steam pipeline, because the alternate of temperature and the structural factor of modulating valve self; Cause steam flow rate instantaneous variation, flash distillation and cavitation, sealing surface is washed away serious and causes serious vibration and noise.Through using general modulating valve big at the amount of leakage of closing fully, the internals well damage is regulated inaccuracy, has had a strong impact on the usability and the life-span of valve.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to existing technology, provides a kind of steam for thermal recovery by rectifying valve, has protected valve seat and valve body, has prolonged the working life of valve, has also reduced the noise of device simultaneously.
Its technological scheme is: comprise valve rod, Stuffing box, support, valve body, handwheel; The upper end of valve body flexibly connects support; The top of valve rod connects handwheel, and the bottom is connected to valve inner through Stuffing box, and described valve inner is provided with the throttling cover; Be provided with the self-tightening filler between Stuffing box and the valve body, Gland and Stuffing box flexibly connect.
Above-mentioned throttling cover adopts guard, and the top of guard is through being bolted to valve inner.
The beneficial effect of the utility model is: be provided with the throttling cover in the valve body of the utility model, protected valve seat and valve body, prolonged the working life of valve, also reduced the noise of device simultaneously; Make the utility model under the running state of high-temperature steam long-term work, can not only play the effect of adjusting, rectification for a long time to medium, the effect that can also play cut-out, end pipeline for a long time.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: Stem Mut 1, valve rod 2, Gland 3, Stuffing box 4, support 5, valve body 6, locking nut 7, handwheel 8, filler 9, fixing bolt 10, self-tightening filler 11, throttling cover 12.
Embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model comprises Stem Mut 1, valve rod 2, Gland 3, Stuffing box 4, support 5, valve body 6, locking nut 7, handwheel 8, filler 9, fixing bolt 10, self-tightening filler 11, throttling cover 12 compositions; Gland 3, filler 9, wherein, the upper end of valve body 6 connects support 5 through fixing bolt 10; The top of valve rod 2 connects handwheel 8 through Stem Mut 1; The bottom is connected to valve inner through Stuffing box 4, and it is characterized in that: described valve inner is provided with throttling cover 12, is provided with self-tightening filler 11 between Stuffing box 4 and the valve body; Gland 3 and Stuffing box 4 are connected through bolt, are provided with filler 9 between Gland 3 and the valve rod.
Wherein, throttling cover 12 adopts guard, and the top of guard is through being bolted to valve inner.
The characteristics of the utility model are following: the one, adopt straight journey cage pressure regulator valve structure, and be provided with the throttling cover in the valve body, protected valve seat and valve body, prolonged the working life of valve, also reduced the noise of device simultaneously.
The 2nd, unbalanced force is little, regulation range is wide, stable action, stuck phenomenon can never occur.
The 3rd, sealing surfaces pile-up welding hard alloy, high temperature resistance, antiscour; Valve seat and flap adopt to cooperate and grind, and good seal performance has overcome the big shortcoming of sealing face leakage amount.
The 4th, adopt the self-tightening sealing structure, pressure, temperature high sealing effect more are good more.
The 5th, steam medium does not directly wash away sealing surface by the flow through little valve cage metering orifice of stem lower portion of throttling cover window, has reduced or remitted the damage of medium to sealing surface.This just structure makes this valve under the running state of high-temperature steam long-term work, can not only play the effect of adjusting, rectification for a long time to medium, the effect that can also play cut-out, end pipeline for a long time.
