Abstract
The patent of the utility model relates to a multi stage decompression maze cage type adjusting valve. Including valve body, disk seat, sealing member, case, valve rod, valve gap, still include the labyrinth valve cage, the labyrinth valve cage comprises the valve cage lower part of components of a whole that can function independently and valve cage upper portion and maze disc, and several maze discs pass through the several fix with screw between valve cage lower part and valve cage upper portion, and the disk seat is placed at the valve body intracavity, and the labyrinth valve cage is placed on the disk seat, is equipped with the sealing member on the case, is fixed with the case setting of valve rod is in the labyrinth valve cage, and the valve gap passes through several double -screw bolt nut to be fixed on the valve body. The effect is: multi stage decompression maze cage type adjusting valve can be effectual to liquid, gaseously shunt hierarchical step -down when the big pressure differential, control case outlet velocity has prevented to wash away, cavitation erosion, vibrations, noise scheduling problem, has guaranteed the life of valve when having ensured the performance of valve. The removable maintenance of labyrinth valve cage simultaneously, internals interchangeability is strong, and is wide to medium temperature application scope.
Description
Technical field
The utility model patent relates to a kind of modulating valve, particularly a kind of multilevel decompression labyrinth cage type regulating valve of medium temperature broadness.
Background technique
At present along with oil, chemical industry, metallurgy, the developing rapidly of power industry, the day by day raising of technological level, to the controlling component of its fluid--the requirement of modulating valve is also more and more higher; Especially in the occasion of High Pressure Difference, conventional valve, in the process used, unavoidablely occurred flash distillation, cavitation, vibration and cavitation phenomenons, greatly reduce the working life of valve, simultaneously with having occurred noise.
Summary of the invention
In view of the situation that above-mentioned prior art exists, the utility model provides a kind of multilevel decompression labyrinth cage type regulating valve.The flow velocity of liquid or gas effectively can be controlled by multi-disc labyrinth disc, thus the high flow rate certainly led to when fundamentally solving High Pressure Difference, and high flow rate brings the serious problems such as vibration, erosion, noise.
The utility model for achieving the above object, the technological scheme adopted is: a kind of multilevel decompression labyrinth cage type regulating valve, comprise valve body, valve seat, Sealing, spool, valve rod, valve gap, it is characterized in that: also comprise labyrinth valve cage, described labyrinth valve cage is made up of the valve cage bottom of split and valve cage top and labyrinth disc, several pieces labyrinth discs are fixed between valve cage bottom and valve cage top by several screw, described valve seat is placed in valve body chamber, described labyrinth valve cage is placed on valve seat, described spool is provided with Sealing, the spool being fixed with described valve rod is arranged in the valve cage of labyrinth, described valve gap is fixed on valve body by several stud nut.
The beneficial effects of the utility model are: adopt the labyrinth valve cage that valve cage bottom, valve cage top and several pieces labyrinth discs are fixedly made up of several screw, by the replacing of labyrinth disc, valve goes for different media (liquid, gaseous state) and different pressure drops.
The manufacture cost of multilevel decompression labyrinth cage type regulating valve concentrates on the valve cage of labyrinth, and valve cage ground labyrinth flow-path complications are narrow and small, if medium contains impurity, then very easily blocked, impact uses.And the structure that this kind is connected by screw, detachable maintenance of clean-up, compares with integral type, and performance is identical, disposable replacing when avoiding blocking, and can safeguard, cost-saving.
Multilevel decompression labyrinth cage type regulating valve, Sealing on valve hole part, spring loaded ring 4-1 is used when medium temperature less than 232 DEG C, use C shape metal ring 4-2 to seal when medium temperature 232 DEG C ~ 538 DEG C, elasticity components and parts, while guarantee sealability, wearing and tearing and expansion are compensated, effectively improves working life.
In sum, multilevel decompression labyrinth cage type regulating valve effectively can carry out shunting classification step-down to liquid, gas when large pressure reduction, control spool outlet velocity, prevent wash away, cavitate, shake, the problem such as noise, ensure that the working life of valve while having ensured the usability of valve.The removable maintenance of labyrinth valve cage simultaneously, internals interchangeability is strong, wide to medium temperature Applicable scope.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is explained in further detail.
As shown in Figures 1 to 5, a kind of multilevel decompression labyrinth cage type regulating valve, comprises valve body 1, valve seat 2, Sealing 4, spool 5, valve rod 6, valve gap 7, also comprises labyrinth valve cage 3.
Labyrinth valve cage 3 is made up of the valve cage bottom 3-1 of split and valve cage top 3-3 and labyrinth disc 3-2, and several pieces labyrinth discs 3-2 is fixed between valve cage bottom 3-1 and valve cage top 3-3 by several screw 3-4.
Valve seat 2 is placed in valve body 1 chamber, and labyrinth valve cage 3 is placed on valve seat 2, and spool 5 cover has Sealing 4, and be fixed with spool 5 device of valve rod 6 in labyrinth valve cage 3, valve gap 7 is fixed on valve body 1 by several stud nut 8.
Sealing 4 is spring loaded ring 4-1 or C shape metal ring 4-2.
When medium temperature less than 232 DEG C, use spring loaded ring 4-1.When medium temperature 232 DEG C ~ 538 DEG C, C shape metal ring 4-2 is used to seal.
Labyrinth disc 3-2 is liquid labyrinth disc 3-2-1 or gas labyrinth disc 3-2-2.
When actuator's band movable valve plug 5 moves up and down, can be changed by the flow of labyrinth disc 3-2, become and realize the control of valve to flow.
In work, when medium is liquid, labyrinth disc 3-2 adopts liquid labyrinth disc 3-2-1, and flow direction is go out at the enterprising end.
When medium be steam or gas time, labyrinth disc 3-2 adopts gas labyrinth disc 3-2-2, and the flow direction of steam or gas is go out on entering at the end.
Because the runner of labyrinth disc 3-2 is made up of multiple bend, medium often flows through a bend, all consumes the kinetic energy of fluid, reduces the speed of fluid, thus abatement fluid washing away internals.The overall process that medium flows in runner is exactly the process of multilevel decompression.
