Abstract
The utility model provides a fluid switch valve comprises handle, elbow, valve pipe, seal port, sealing washer, disk seat, base, support, the fixed lid of toper, valve outer tube, two way seal circle etc.. Valve guan ke in the valve outer tube horizontal rotation with reciprocate, it is again the partly of valve that the valve pipe is the runner, utilizes the sealing washer on valve seal of tube mouth and the disk seat, realizes the break -make on -off control of convection cell, presses the handle, sealing washer entering seal port, the fluid is cut off. The pull -up handle, the seal port breaks away from with the sealing washer, and the fluid flows through valve pipe and elbow.
Description
Art
The utility model relates in pipe-line system the valving connecting or block fluid in pipeline.
Background technique
The valve of known control fluid on-off, structurally mainly contains pipe valve shape, gated type, butterfly, spherical, as stop valve, gate valve, butterfly valve, ball valve etc.
Existing valve all takes the mode directly opening or closing runner, realizes the switch control rule of convection cell, as: pipe valve valve and gated type valve, switch drive moment is large, and must control open and close with screw rod, the open and close time is long; The valve plate of fly valve blocks water seriously in a fluid, and local velocity is disorderly, and fluid dynamic energy loss is large; Ball valve requires that machining accuracy is high, is not suitable for making the valve that can control large flow fluid.
Summary of the invention
In order to overcome the deficiency of known valve, the utility model provides a kind of operation control moment little, and switching time is short, and fluid dynamic energy loss is little, is applicable to the valve fluid of various flow being carried out to switch control rule.
The technological scheme that the utility model adopts is: this device is made up of handle, elbow, valve tube, sealed mouth, guide and limit sheet, seal ring, lip, valve seat, nut, base, support, taper fixed cover, bolt, valve outer tube, screw cap, seal groove, two-way sealing ring etc.Valve tube can horizontally rotate and move up and down in valve outer tube, valve tube is runner and a part for valve, utilize the sealed mouth of valve tube and be in the seal ring on the valve seat in the middle of runner, the on-off switch realizing convection cell controls, and press handle, valve tube moves down, under the guiding on the cone inclined-plane of taper fixed cover, seal ring on valve seat enters in the sealed mouth of valve tube, and fluid is cut off, and makes switch valve be in cutout closed condition.Because valve tube inside communicates with air, firmly very little during squeeze grip.On pull handle, valve tube moves, and the sealed mouth of valve tube and seal ring depart from, and fluid flows out through valve tube and elbow.
The beneficial effects of the utility model are; The break-make utilizing the seal ring on the sealed mouth of valve tube and valve seat to realize convection cell controls, and valve tube is runner and a part for valve, during closedown, seal ring on the direct shutoff valve seat of sealed mouth of valve tube, break-make control force is little, and structure is simple, and switching time is short.The flow-passing surface product moment of valve outer tube and valve tube is little, and the kinetic energy rejection of fluid is little, crosses streamflow large.
Accompanying drawing explanation
Further illustrate the utility model below in conjunction with accompanying drawing 1 and embodiment, Fig. 1 is principle of the invention figure.
In Fig. 1: 1. handle, 2. elbow, 3. valve tube, 4, straight tube, 5. sealed mouth, 6. guide and limit sheet, 7. seal ring, 8. lip, 9. valve seat, 10. nut, 11. bases, 12. supports, 13. taper fixed covers, 14. cone inclined-planes, 15. bolts, 16. valve outer tubes, 17. screw caps, 18. seal grooves, 19. two-way sealing rings.
Embodiment
In FIG, handle (1), elbow (2), valve tube (3) are fixed together.Base (11) and valve outer tube (16) are fixed together.Sealing seat (9) is connected to one by support (12) and base (11), utilizes bolt (15) and nut (10) taper fixed cover (13) and seal ring (7) to be fixed on valve seat (9).Two-way sealing ring (19) is fixed in the seal groove (18) at valve outer tube (16) top by screw cap (17), forms fluid proof seal.Taper fixed cover (13) is frustum shape, its effect is fixed seal ring (7), when valve tube (3) moves down, utilize cone inclined-plane (14) to lead to sealed mouth (5), seal ring (7) is entered in sealed mouth (5) smoothly.
Closing process: squeeze grip (1) downwards, valve tube (3) moves downward, under the cone inclined-plane (14) of taper fixed cover (13) guides, seal ring (7) enters among sealed mouth (5), the lip (8) of seal ring (7) periphery is under effect of water pressure, lip (8) hoop extrusion expansion, sealing is tighter, and fluid is disconnected.Diameter due to sealed mouth (5) is greater than the external diameter of straight tube (4), water pressure has downward active force to valve tube (3), make fluid switching valve be in reliable and stable closed condition, two-way sealing ring (19) has blocked through the interstitial fluids seepage between straight tube (4) and valve outer tube (16).
Opening process: upwards promote handle (1), valve tube (3) moves upward, sealed mouth (5) and seal ring (7) depart from, fluid is flowed into by the bottom of base (11), as shown in the direction of arrow, flow out through valve tube (3) and elbow (2).Valve tube (3) moves on continuing, guide and limit sheet (6) enters the top of valve outer tube (16) and the bottom of two-way sealing ring (19), both ensured that valve tube (3) can horizontally rotate in (16), again limit valve tube (3) to rock in valve outer tube (16), now fluid switching valve is opened completely.
Claims (4)
1. a fluid switching valve, be made up of handle, elbow, valve tube, seal ring, valve seat, base, support, taper fixed cover, bolt, valve outer tube, seal groove, screw cap, two-way sealing ring, it is characterized in that: valve outer tube is fixedly connected with base, valve seat is connected to one by support and base, with bolt and taper fixed cover, seal ring is fixed on and is on the middle valve seat of runner, valve tube can horizontally rotate and move up and down in valve outer tube, utilize the seal ring on the sealed mouth of valve tube and valve seat, the on-off switch realizing convection cell controls.
2. a kind of fluid switching valve according to claim 1, it is characterized in that: valve tube is made up of straight tube, sealed mouth and guide and limit sheet, the diameter of sealed mouth is greater than the external diameter of straight tube, after closedown, seal ring is among the sealed mouth of valve tube, during unlatching, the sealed mouth of valve tube is separated with the seal ring on valve seat.
3. a kind of fluid switching valve according to claim 1, is characterized in that: taper fixed cover is frustum shape, and border is cone inclined-plane.
4. a kind of fluid switching valve according to claim 1, is characterized in that: seal groove is arranged at the top of valve outer tube, places two-way sealing ring in seal groove.
