Abstract
The utility model discloses a capsule valve, which is composed of a valve casing, a control valve pipe, and a flange short pipe. The middle parts of the flange on the upper end of the valve casing and the flange of the control valve pipe are provided with annular flat washers on the upper part of a rubber capsule, and a circular pipe on the middle part of the rubber capsule and a sphere on the lower part of the rubber capsule are arranged in the cavity of the valve casing. The capsule valve has the advantages of simple structure, easy fabrication, reliable work, and low cost, and can be used for controlling the pipeline fluid.
Description
It is the capsule valve of power with the fluid that the utility model belongs to a kind of, is applicable to the actuator of pipeline fluid control.
Existing is the piston valve of power with the fluid, is to promote piston by fluid to drive the spool action, makes opening of valves or closes.Piston valve is made up of piston, spool, Sealing etc.Because the movable part in the piston valve and the performance of Sealing all can make the reliable operation performance of valve reduce, and the machining accuracy of spool and piston all requires than higher, so piston valve construction is complicated, cost is also higher.
The purpose of this utility model provide a kind of simple in structure, make easily, reliable operation, capsule valve that cost is low.
The purpose of this utility model is achieved in that the annular plain cushion on dress rubber bag tank top in the middle of the flange of valve casing upper flanges and control valve pipe, and the pipe at rubber bag tank middle part and the ball of bottom are placed in the chamber of valve casing.
The utility model is because only adorn a rubber bag tank in the valve casing chamber, after in rubber bag tank, charging into the fluid bigger than controlled fluid pressure, rubber bag tank will expand, at this moment valve is closed condition, when discharge fluid in rubber bag tank after, rubber bag tank will shrink, and valve is opening state, this valve does not have other moving elements and Sealing, so this valve arrangement is simple, make easily, reliable operation, cost are low.
Below in conjunction with accompanying drawing enforcement of the present utility model is described in detail.
Figure is the sectional drawing of capsule valve of the present utility model.
As shown in the figure, capsule valve by a main body be spherical upper end and about two ends respectively be provided with the rubber bag tank of adorning in the flange short tube 6, valve casing 2 chambeies of control valve pipe 1, the valve casing 2 two ends dress of valve casing 2, the valve casing 2 upper ends dress of flange 11 7 and form.Adorn two flange gaskets 3 between the flange 11 of the flange end of flange short tube 6 and valve casing 2 two ends, the flange 11 of two ends of valve casing 2 is connected by bolt 4 with the flange end of flange short tube 6 respectively, and the nose end of two ends flange short tube 6 can be connected in the controlled pipeline then.Control valve pipe 1 upper end is the mouth of pipe, the lower end be flange 11 ', the flange 11 of valve casing 2 upper ends and the flange 11 of control valve pipe 1 ' be connected by bolt 4, the mouth of pipe of control valve pipe 1 can be connected with controlling plumbing fixtures.The bottom of rubber bag tank 7 is balls 10, the middle part is a pipe 9, top is annular plain cushion 8, and they are an integral body, its annular plain cushion 8 be the flange 11 that is installed in control valve pipe 1 ' with the centre of valve casing 2 upper flanges 11, make the pipe 9 at rubber bag tank 7 middle parts, the ball 10 of bottom place in the chamber of valve casing 2.After preventing that rubber bag tank 7 from being charged into fluid, its underpart ball 10 expand into the position of flange short tube 6, in the middle of two flange gaskets 3 of valve casing 2 two end flange 11 filter screen 5 is housed respectively.
The working principle of capsule valve: when controlling plumbing fixtures through the control valve pipe charges into the fluid bigger than controlled fluid pressure in rubber bag tank 7 after, the ball of rubber bag tank 7 bottoms 10 expands, and closely connected with valve casing 2 inwalls, at this moment valve is in closed condition; When controlling plumbing fixtures gives off fluid in rubber bag tank 7, at this moment the ball 10 of rubber bag tank 7 bottoms shrinks opening of valves.
Claims (2)
