Description
The technical field is as follows:
the invention relates to a regulating valve, in particular to a regulating valve for precisely distributing two paths of fluid flow, which is widely applied to an automatic control system of industrial processes in industries such as electric power, petroleum, chemical engineering, metallurgy, environmental protection, light industry, scientific research equipment and the like, and is used in a fluid supply system of a high-temperature high-pressure steam pipeline.
Background art:
the steam pipeline control system in the fields of power stations, metallurgy, chemical industry, oil fields and the like is widely applied. However, in high temperature high steam pipelines, the flow to the fluid system cannot be precisely adjusted.
The traditional fluid regulating valve cannot accurately regulate the flow. No special valve, namely a regulating valve for precisely distributing two paths of fluid flow, is found in the variety of the valves of the fluid pipelines; the lever type fine adjustment fluid distribution regulating valve ensures the accuracy of regulation, and the area of a window formed by the valve clack and a valve seat is changed by regulating the position of the valve clack through a lever type structure, so that the aim of quickly regulating the distribution flow is fulfilled.
The invention content is as follows:
the invention aims to provide a novel regulating valve for precisely distributing two paths of fluid flow, which can realize the purpose of quickly regulating and distributing the flow by regulating the position of a valve clack through a lever type structure to change the area of a window formed by the valve clack and a valve seat. The automatic control system is used in a fluid supply system of a steam pipeline of an automatic control system and has the effect of convenient operation.
The invention has the technical scheme that the lever type fine adjustment fluid distribution regulating valve comprises a valve body, an outflow fluid connecting pipe, a sealing gasket, a valve cage, a regulating valve rod, a sealing gasket, a hinge bolt, a nut, a filling gasket, a valve cover, a filling material, a clamping plate, a pin shaft, a split pin, a support, a lever and a heavy hammer; the valve body is provided with an inlet and two outlets, the valve body is cylindrical, the inlet is arranged in the middle of the side wall of the cylinder, the middle of the side wall of the cylinder is wrapped with a valve seat, the valve seat is a valve cage with a cylindrical cage-shaped structure, a valve core is arranged in the valve cage, the valve core is a rod-shaped valve core rod which moves up and down 5-20mm in the valve cage, the valve core rod is waist-shaped at the level position of the valve cage, the upper end and the lower end of the valve core rod are in sealing fit with a closed ring at the upper end and the lower end of the cylindrical valve cage, the outlets of the valve are respectively arranged on the side walls at the upper end and; the upper end of the valve core rod is fixed with a valve rod, and the center of the valve rod, which penetrates through the valve cover, is provided with a packing pad and packing; the valve body is provided with a lever, the head of the lever is fixed on the valve body as a fulcrum, the center of the lever is a resistance point, the lever presses the uppermost end of the valve rod at the position of the resistance point, and the position of the hammer on the lever can be adjusted at the tail position of the lever.
The position of the weight on the tail part of the lever can be adjusted. Cylindrical refers in particular to a cylinder.
Because the valve core rod is waist-shaped at the leveling position of the cage-shaped valve seat, the diameter of the valve core rod is smaller than the diameter of the main body of the valve core rod, the length of the waist-shaped valve core rod is longer than the length of the cage-shaped valve seat, when the waist center of the waist-shaped valve core rod is leveling with the center of the cage-shaped valve seat, gaps are left at the upper and lower parts of the waist center of the waist-shaped valve core rod and the cage-shaped valve seat, the upper and lower gaps are respectively communicated with the two outlets, and fluid can pass through the gaps of the valve cage from the inlet to the upper and lower; when the valve core rod moves upwards on the cage-shaped valve seat, a larger space for fluid to pass through is reserved at the upper end of the girdling-shaped gap, the amount of fluid flowing out of an outlet at the upper end is large (when the valve core rod moves upwards to a limit position, the valve core rod has no gap at the lower end of the cage-shaped valve seat, and the fluid flow of an outlet at the lower part is stopped); when the valve core rod is arranged at the central position of the cage-shaped valve seat, the upper outlet and the lower outlet have uniform fluid flow, and the different positions of the valve core rod provide the distribution of the fluid flow of the upper outlet and the lower outlet.
Furthermore, the leveling position of the girdling of the valve core rod of the cage-shaped valve seat is a convex arc shape, namely the cage-shaped valve seat is in a waist drum shape.
Furthermore, the fluid flow at the inlet has a certain pressure and tends to press the valve core rod at the central position, and because the fluid needs to be controlled, the weight is arranged at the tail part of the lever and presses the lever to ensure that the fluid flow is mainly downward, and when the fluid flow at the upward outlet needs to be increased, the pressure of the weight is reduced. The position of the girdling of the valve core rod of the cage-shaped valve seat is an outward convex arc shape, namely the cage-shaped valve seat can be in a waist drum shape.
Furthermore, the inlet and the outlet are provided with pipe joints, and the outer ends of the pipe joints are provided with flanges.
As shown in the figure, the heavy hammer is controlled by the control mechanism, the lever is acted, the valve core of the valve rod is adjusted in a lifting mode or a descending mode, so that the valve flow channel can be opened in different degrees, and the distribution and accurate control of the pipeline flow can be achieved.
The beneficial effects are that, the valve body and the inlet and outlet are integrally forged, the integral strength is guaranteed, especially the integral strength under the high-temperature and high-working condition is guaranteed, and the service life of the regulating valve is guaranteed. The shape of the longitudinal surface from the gap of the valve cage to the girdling-shaped gap of the valve core rod at the flush position of the cage-shaped valve seat is the shape which enables the area of the flow to be uniformly changed in direct proportion, the change of the flow is a distributed equal percentage structure, and the accurate adjustment of the flow is ensured. The lever and weight type mechanism is adopted to adjust the position of the weight on the lever, so that the adjusting position of the valve core rod in the center of the cage-shaped valve seat can be adjusted, the flow can be adjusted, the adjustment is convenient, the adjustment accuracy of the flow is ensured, the lever and weight type mechanism is adopted, the adjustment opening and adjustment are convenient, and the control of the automatic control mechanism is convenient. The packing adopts a double-sealing packing box design, and the sealing is reliable. The surface of the valve core and the sealing surface of the valve seat are welded by different hard alloy surfacing technologies. The wear resistance and corrosion resistance of the valve core and the valve seat are ensured, and the service life of the whole valve is ensured.
