Abstract
The utility model relates to a gasket pressurizing flat sealing plane valve. Valve plates with calve openings are superposed to form the gasket pressurizing flat sealing plane valve. The gasket pressurizing flat sealing plane valve is characterized in that a sealing gasket is arranged between the superposing surfaces of the valve plates. The sealing gasket and the valve plates form sealing pressurizing chambers. The sealing pressurizing chambers are provided with inlets and outlets of pressurizing flow media.
Description
Affiliated technical field
The utility model relates to a kind of plane sealing valve type device, relates in particular to the plane valve of multichannel sealing.
Background technique
Using in the prior art has the valve plate of valve port to be superimposed together, relative movement by valve plate, the dull and stereotyped multi-way valve of a class that makes valve port connect or close, its sealing means is to utilize the superimposed sealing plane of valve plate closely to contact and install seal ring on valve port to seal, sealing plane wearing and tearing and scuffing easily in the use, and be difficult to eradicate the disadvantage of scraping volume when seal ring is moved by valve plate.
Summary of the invention
The utility model provides a kind of liner pressure sealing plane valve to overcome the deficiencies in the prior art at above-mentioned problem, and this liner pressure sealing plane valve can not cause the wearing and tearing of valve plate sealing plane and scratch, and does not also install seal ring on valve port.
Technical solution adopted in the utility model is in the valve of liner pressure sealing plane, between every valve plate superposed surfaces that needs to seal liner is set.It is characterized in that: in two superposed surfaces, one still is the plane, and another then is provided with the valve port step circle of protrusion on each valve port, the end face that valve port step circle protrudes with superimposed valve plate plane be the plane that cooperatively interacts; Liner is provided with and the corresponding liner oral pore in valve port numbers of steps, size and position, and the driving fit encapsulation is on corresponding valve port step circle, the valve plate marginal fit of the edge of liner and institute's encapsulation makes the pressurized chamber that forms sealing between the valve plate of liner and institute's encapsulation; The pressurized chamber is provided with the pressurized flow medium and imports and exports.The utility model is imported and exported to pressurized chamber pressurization with flowing medium from the pressurized flow medium by said structure, liner can be pressed on the valve plate plane that needs sealing, tightly seals each valve port; After the release of pressurized flow medium, then liner unclamps from sealed valve plate plane, keeps certain gap of moving about between the two, do not have the trouble of scraping the volume Sealing again, and resistance to motion is also very little.
During the utility model sealing valve port, remove the sealing valve port circle, adopted liner multichannel to seal, simple in structure, be better than prior art.
Description of drawings
Below in conjunction with embodiment's accompanying drawing the utility model is further described.
Accompanying drawing is the utility model embodiment's a partial sectional view.
1-3. valve plate among the figure, the 4-5. liner, the liner oral pore on the 6-10. liner, the protrusion step circle on the 11-15. valve plate, the 16-17. pressurized chamber, the 18-19. flowing medium is imported and exported, 20-27. valve port, 28., 29. packing rings, 30. fastening nuts.
Embodiment
Valve plate in the accompanying drawing (1), (2) and be equiped with liner (4) between the valve plate (3), (5), liner oral pore (6) on the liner, (7), (8), (9), (10) encapsulation is in valve plate (1), (2) go up corresponding protrusion step circle (11), (12), (13), (14), (15) go up also driving fit with it, the edge by clamping bolt (30) with valve plate (1), (2) and liner (4), (5) with packing ring (29) fit sealing, in liner (4), (5) with the valve plate (1) of institute's encapsulation, (2) constitute airtight pressurized chamber (16) between, (17), if import and export (18) from the pressurized flow medium, (19) to pressurized chamber (16), (17) pressurization, liner (4) then, (5) be pressed on the sealing plane of valve plate (3), tightly seal each valve port (20) and (25), (21) with (25), (22) with (26), (23) with the junction point of (26) and the airtight valve port (24) that bars up, (27).Unclamp from the sealing plane of valve plate (3) liner after the pressurizing medium release (4), (5), keeps certain gap of moving about between the two, so that valve plate (3) is the keying control that relative movement conversion valve port is made at the center with axle (28).
Claims (1)
- The utility model provides a kind of liner pressure sealing plane valve of being made up of valve plate and liner, it is characterized in that between the superposed surfaces of valve plate, being provided with the liner that adapts with valve plate, valve plate and liner constitute the pressurized chamber, have flowing medium to import and export in the pressurized chamber, the liner that is installed between valve plate is pressed on the valve plate that needs sealing.
