Abstract
A device controlling flowing and stopping of fluids mainly comprises a switch handle, an inner tube, an outer tube, an inflow opening, an upper sealing ring, a lower sealing ring, a base, an inner tube counterbore, an inner tube sealing surface, an inner tube guide piece, an outflow opening and the like. When the device needs to be closed, the switch handle is pressed, the inner tube sealing surface is inserted into the lower sealing ring so that the device can be in a stopping closed state, and when the device needs to be opened, the switch handle is pulled upward, the inner tube sealing surface is separated form the lower sealing ring, and the fluids flow out from the outflow opening.
Description
Affiliated technical field
The utility model relates to the valving of connecting or block fluid in pipeline in pipe-line system.
Background technique
The valve of known control fluid break-make, structurally mainly contains pipe valve shape, gated type, butterfly, cock and spherical, as stop valve, gate valve, butterfly valve, stopcock, ball valve etc.
Existing valve all takes the direct shutoff of valve to enter the mode of head piece, causes the increase of shutoff pressure or area of passage to reduce, as: the driving moment of pipe valve valve and gated type valve is large, must use the open and close of screw rod control valve, and the open and close time is long; The area of passage of pipe valve shape valve and fly valve dwindles, and fluid dynamic energy loss is large; Ball valve machining accuracy is high, involves great expense, and as there being impurity in pipeline, easily by impurity, is stopped up, and causes valve to open.
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 fluid dynamic energy loss is little, is applicable to the device that various fluid break-makes are controlled.
The technological scheme that the utility model adopts is: this device is by switch handle, inner tube, outer tube, enter head piece, lower seal circle, base, inner tube cone mouth, inner tube sealing surface, inner tube guiding piece, upper sealing gasket, go out the compositions such as head piece, inner tube can horizontally rotate and move up and down in outer tube, inner tube is runner and valve, during cutout, the not direct shutoff of inner tube enters head piece, the break-make of utilizing lower seal circle on inner tube sealing surface and base to realize convection cell is controlled, press switch handle, inner tube moves down, under the guiding of inner tube guiding piece, the internal diameter of inner tube taper mouth aligned with lower seal ring, the external diameter of inner tube taper mouth end is less than the internal diameter of lower seal circle, continue push switch handle, when inner tube taper mouth is inserted into base, inner tube sealing surface inserts in lower seal circle, form sealing, make device in cutout closed condition, the head piece that goes out being communicated with inner tube communicates with outside atmosphere, it is very micro-that inner tube is affected by internal pipe pressure, press down while closing firmly very little, upper drag switch handle, in inner tube, move, inner tube sealing surface and lower seal circle depart from, fluid flows into inner tube through entering head piece, by going out head piece, flow out, base is dismountable housing, sludge in can containing fluid.
The beneficial effects of the utility model are; The break-make of utilizing lower seal circle on inner tube sealing surface and base to realize convection cell is controlled, and inner tube is runner and valve, during cutout inner tube directly shutoff enter head piece, break-make control moment is little, simple in structure, the diameter of outer tube and inner tube is poor little, and the kinetic energy rejection of fluid is little.
Accompanying drawing explanation
Below in conjunction with accompanying drawing 1 and embodiment, the utility model is further illustrated.
In Fig. 1: 1. switch handle, 2. inner tube, 3. enters head piece, 4. lower seal circle, 5. base, 6. inner tube cone mouth, 7. inner tube sealing surface, 8. inner tube guiding piece, 9. outer tube, 10. upper sealing gasket, 11. go out head piece.
Embodiment
In Fig. 1, closing process: downward push switch handle (1), inner tube (2) moves downward along the inwall of outer tube (9), under the guiding of inner tube guiding piece (8), the internal diameter of inner tube taper mouth (6) aligned with lower seal ring (4), when inner tube taper mouth (6) is inserted into base (5), inner tube sealing surface (7) inserts in lower seal circle (4), fluid cannot flow in inner tube (2) by entering head piece (3), fluid is disconnected, device forms closed condition, upper sealing gasket (10) is between inner tube (2) and outer tube (9), avoid fluid by oozing out between inner tube (2) and outer tube (9).
Opening process: upwards promote switch handle (1), inner tube (2) moves upward, inner tube sealing surface (7) departs from lower seal circle (4), and fluid enters inner tube (2) by entering head piece (3), through going out head piece (11), flows out.
Claims (2)
1. a device of controlling fluid break-make, by switch handle, inner tube, outer tube, enter head piece, upper sealing gasket, lower seal circle, base, inner tube cone mouth, inner tube sealing surface, inner tube guiding piece, go out head piece and form, it is characterized in that: inner tube is runner and valve, during cutout, the not direct shutoff of inner tube enters head piece, under the guiding of inner tube guiding piece, the internal diameter of inner tube taper mouth aligned with lower seal ring, the break-make of utilizing lower seal circle on inner tube sealing surface and base to realize convection cell is controlled.
2. a kind of device of controlling fluid break-make according to claim 1, is characterized in that: the external diameter of inner tube taper mouth end is less than the internal diameter of lower seal circle.
