Abstract
The invention relates to a sealed adjustor for a double-sealing multiport valve, which consists of a valve body, a valve core and a valve cover. The invention is characterized in that a circular groove is additionally arranged on a wide band of a metal sealing surface of a valve seat base where a valve core transverse hole is in butt joint with inlets, and an assistant sealing plastic ring is placed in the groove; a plug hole is arranged between two inlets of the valve body and a plug head and an O-shaped sealing ring are arranged in the hole. The invention has the advantages of better sealing performance, is convenient to adjust seal, saves labor and time, wastes no crude oil and neglects neither gathering and transportation of normal oil-way nor measuring seal adjustment in the valve.
Description
Technical field
The present invention relates to a kind of multiple-way valve that is used for crude oil transmission and shunting metering, particularly a kind of sealing regulating device of double-sealing multiple-way valve.Belong to technical field of sealing technology.
Background technique
A kind of multiple-way valve that uses in the defeated and shunting metering process at the collection of crude oil at present, it is realized that collection is defeated and is characterised in that with shunting function of measuring separately the transverse holes of an intercommunication and vertical hole are arranged in the T-valve core of this multiple-way valve.Vertically the outlet in hole is connected with measuring apparatus, and transverse holes can connect around 360 ° of rotations of axis and any inlet with spool.When the transverse holes on this spool was not docked with any inlet, this valve was realized the collection transmission function, otherwise realizes metering and the defeated synchronizing function of collection.Since the frequent conversion of this valve function, thereby cause only one seat ring sealing surface broadband abrasion aggravation on the spool transverse holes, reduced tightness, cause the leakage of crude oil.The traditional solution is: stop multiple-way valve work, removal any one with the pipeline that is connected of inlet, rotary spool makes the transverse holes aligned inlet in the spool, again with inner hexagon spanner put in rotation adjusting nut to sealing suitable till.The shortcoming of this multiple-way valve and adjusting method is: it is unreliable to seal, and when sealing adjustment must stop the work of multiple-way valve, adjust loaded down with trivial details, delay work, mistake, and when adjusting, cause a large amount of wastes of crude oil in the pipeline.Therefore, design a kind of better tightness, adjustment seals easily multiple-way valve and seems quite necessary.
Summary of the invention
The object of the present invention is to provide a kind of sealing regulating device of double-sealing multiple-way valve, it both can improve sealability, and convenient again the adjusting seals.
In order to realize above-mentioned purpose, technological scheme of the present invention is: be made up of valve body, spool, valve gap.It is characterized in that: on the seat ring metallic sealing section broadband that inlet connects, set up circular groove in the spool transverse holes, be placed with the auxiliary seal teething ring in the groove; Between valve body two inlets, be provided with a pipe plug opening, be provided with plug head and O RunddichtringO in the hole; Described auxiliary seal teething ring is to be processed by the special engineering plastics polyether-ether-ketone.
It is better that the present invention has sealability, and adjustment sealing is convenient, fast, the saving of labor, saves time, and do not waste crude oil, normal oil circuit collection defeated with valve in the metering sealing adjustment advantage of neglecting neither.
Description of drawings
Accompanying drawing 1 is a B-B revolved sectional view in the accompanying drawing 2
Accompanying drawing 2 is an A-A sectional view in the accompanying drawing 1
Accompanying drawing 3 is the I enlarged view in the accompanying drawing 2
Among the figure; 1 be valve gap, 2 for spool, 3 for valve body, 4 is inlet, 5 be pipe plug opening, 6 for general export, 7 for shunting metering outlet, 8 for interior hexagonal adjusting nut, 9 for seal ring, 10 for the auxiliary seal teething ring, 11 for seat ring, 12 for butterfly spring, 13 for O RunddichtringO, 14 be the plug head.
Embodiment
In accompanying drawing 1,2,3, the horizontal nose end of spool 2 is equipped with interior hexagonal adjusting nut 8, seal ring 9, seat ring 11, butterfly spring 12.The end face of seat ring 11 is provided with annular slot; Groove is built-in with auxiliary seal teething ring 10; Thereby form between seat ring 11 and valve body 3 inwalls, the double seal assistant between auxiliary seal teething ring 10 and valve body 3 inwalls, and these auxiliary seal teething ring 10 employing high-tech special engineering plastics polyether-ether-ketones are processed.Spool 2 can be around self axis rotation.6, one shunting meterings of 4, one general exports of a plurality of single inlets outlet 7 is arranged on the valve body 3, between two single inlets, be provided with a pipe plug opening 5, have plug head 14 to add 13 plugs for seal of O RunddichtringO on the pipe plug opening 5.When rotary spool 2, make in the spool 2 lateral aperture not with valve body 3 on any one single inlet 4 when connecting, it is that crude oil goes into from a general export 6 from a plurality of single inlets 4 that the present invention is in the defeated state of collection.When rotary spool 2 made that any one single inlet 4 connects on lateral aperture and the valve body 3 in the spool 2, the present invention was in the crude oil in this single inlet is measured the sync state that continues crude oil transmission with other single inlet.When rotary spool 2 connected lateral aperture and the pipe plug opening 5 on the valve body 3 in the spool 2, the present invention was in the sync state that adjustment sealing and other single inlet continue crude oil transmission.Unload plug head 14 during adjustment; With long handle inner hexagon spanner hexagonal adjusting nut 8 in pipe plug opening 5 gets into and rotates; Compressing butterfly spring 12 makes its elastic force act on seat ring 11 and the auxiliary seal teething ring 10 through seal ring 9, realizes the sealing adjustment to double seal assistant.
Claims (3)
1. double-sealing multiple-way valve sealing regulating device, it is made up of valve body, spool, valve gap, it is characterized in that described spool transverse holes set up circular groove on the seat ring metallic sealing section broadband that connects that enters the mouth; Be provided with a pipe plug opening between valve body two inlets, be provided with plug head and O RunddichtringO in the hole.
2. as claimed in claim 1 a kind of can be convenient the double-sealing multiple-way valve of adjustment sealing, its characteristic also is to be placed with in the described circular groove auxiliary seal teething ring.
According to claim 1 or claim 2 a kind of can be convenient the double-sealing multiple-way valve of adjustment sealing, its characteristic is that also described auxiliary seal teething ring is to be processed by the special engineering plastics polyether-ether-ketone.
