Abstract
A sealing method for valve, that is arranging valve pin in the valve chamber, opening and closing the valve chamber by the valve pin controlled by the transmission mechanism out of the valve body according to the flowing direction of material. The valve for implementing the method, comprises a valve body and a valve pin. On the inner wall of the valve chamber, circular bead is arranged along the flowing direction of material, on the circular bead, a valve pin connected to the outer transmission mechanism is arranged. The valve pin is driven by the transmission mechanism to open, close or open in different angle for controlling the flow rate of material. For the valve is mounted in the same direction with the flowing material, it can be sealed more tightly. The transmission mechanism is composed of a driving wheel and a driven wheel. The invention has advantages as simple design and convenient assembly-disassembly.
Description
Technical field
The invention belongs to a kind of industrial valve, relate to its sealing means and a kind of novel valve is provided.
Background technique
In existing industrial valve, the seal form of valve is a static seal, in use, seal leakage usually occurs, particularly in Chemical Manufacture because valve seal lost efficacy, cause chemical product to scrap example many.What is more, also can cause the explosive accident of product.
Summary of the invention
Technical problem to be solved by this invention provides a kind of sealing means of valve and a kind of novel valve that is fit to this mode is provided, and sealing is tight, and especially material pressure is high more, seals tighter.
The sealing means of valve of the present invention, its major technique characteristics are in the valve pocket in valve body spool to be set, and spool is closed or opened valve pocket and handled by the outer driving mechanism of valve body, and spool to close the direction of valve pocket identical with the flow direction of material.
Sealing means of the present invention will reach spool exactly, and to bear material pressure big more, seals tighter.
On the inwall of valve pocket shoulder is set, spool is arranged on the shoulder position.Shoulder is to be used to stop spool, just in time closes valve pocket when spool is fitted on the shoulder.
Realize the valve of the invention described above sealing means, comprise valve body, spool, its technical characterstic is to be provided with shoulder in the Flow of Goods and Materials direction on the valve pocket inwall of valve body, and the shoulder place is provided with spool, and spool connects and is arranged on the outer driving mechanism of valve body.
Spool is the parts of closing valve pocket, drives spool by the operation driving mechanism, from but the cut-off valve chamber still keeps valve pocket to be opening state, but also can make spool be the opening state of different amount, the size of decision flow.The installation direction of valve is consistent with the flow direction of material, and it is tighter that the pressure of material can make spool and valve body cooperate, and material pressure is high more, and the pressure that spool bears is big more, seals tighter.
Spool generally is connected with driving mechanism by transmission shaft, the effect of driving mechanism is exactly to drive spool to be fitted in and (to close valve pocket) on the shoulder or open valve pocket, as long as reaching this purpose, its mode of structure all can, the invention provides a kind of preferred and reliable mode of structure is: driving mechanism is meshing with each other by driving wheel and follower and forms, and follower is connected with spool by transmission shaft.Because valve of the present invention more is applicable to commercial Application, Chemical Manufacture pipeline particularly, the pressure ratio of bearing is bigger, so the mode that meshes by driving wheel (gearwheel) and follower (small gear) can alleviate operation strength and labor intensity, and when spool is in incomplete opening state, spool also is subjected to the pressure of Flow of Goods and Materials, is unlikely to this pressure and drives spool self acting stop valve chamber conversely.When preventing that spool is in incomplete opening state, the pressure of Flow of Goods and Materials drives spool self acting stop valve chamber conversely, also can adopt Worm-gear type by driven wheel, has auto-lock function.
Because valve body is generally in a tubular form, so spool is in the form of annular discs, can the periphery of disk a bit be arranged on valve body outside driving mechanism be connected.
Joint place relative and shoulder is added with polytetrafluoroethylsealed sealed pad on the described spool.
The valve pocket of valve and valve body all can serve as a contrast anti-corrosion material processing such as tetrafluoro, and easy to use having the occasion of corrosion, and using scope is extensive, is convenient to promote the use of.
The flange at the valve body two ends of valve is convenient to the installation with pipeline, and flange and valve length all can design by NBS, and is in full accord with existing valve, can mount and dismount easily.Valve body can be selected material according to working pressure, as cast steel, stainless steel etc.
Advantage of the present invention:
(1) simplicity of design is convenient to processing;
(2) installation, convenient disassembly are easy to use;
(3) the valve installation direction is consistent with the Flow of Goods and Materials direction, and it is tightr by means of the pressure of material spool and valve body to be cooperated, and material pressure is high more, and the pressure that spool bears is big more, seals tighter;
(4) spool aperture adjustable size joint can carry out Flow-rate adjustment easily;
(5) spool can take out spool easily after sealing gasket damages, and changes sealing gasket, is convenient to reusing of valve, prolongs the working life of valve.
Description of drawings
Fig. 1 is the structural representation of valve of the present invention;
Fig. 2 is the driving mechanism principle schematic, and the A that also is Fig. 1 is to view.
Among the figure: 1 valve body, 2 flanges, 3 followers, 4 driving wheels, 5 valve pockets, 6 spools, 7 sealing gaskets, 8 shoulders, 9 handwheels, 10,11 transmission shafts, 12 keyways
Embodiment
Fig. 1,2 is the embodiments of the invention structural representation, below in conjunction with description of drawings:
The two ends of valve body 1 have flange 2, along Flow of Goods and Materials direction (arrow is represented the Flow of Goods and Materials direction among Fig. 1) shoulder 8 is set on inwall in the valve pocket 5, spool 6 is in the form of annular discs, its periphery place is connected with transmission shaft 11 keys, transmission shaft 11 driving mechanism outer with being positioned at valve body is connected, this driving mechanism is by gearwheel driving wheel 4 and 3 engagements of small gear follower, and driving wheel 4 connects handwheel 9.On spool 5 relatively and the shoulder joint place be added with polytetrafluoroethylsealed sealed pad 7.
Rotate the drive driving mechanism by handwheel 9 and drive valve core rotation, spool is fitted on the shoulder 8, close valve pocket by transmission shaft 11; Perhaps make spool have aperture, open valve pocket.
The dotted line position of spool is the spool enable possition among Fig. 2.
