Description
Technical field:
The present invention relates to a kind of ball valve of mechanical field.Particularly can improve and guarantee the grey fixed valve body of unloading of reliable sealing working life.
Background technique:
Enterprises such as metallurgy, generating are in the delivery line that contains ash, slag or other particulate matter at present, and the bigger ball valve of general use is in the working procedure; The wearing and tearing of big ball valve and sealing are the technical barriers of puzzlement related domain always; When wanting to make between valve seat and the spheroid sealing better, will between valve seat and spheroid, add bigger pretightening force, when valve seat and spheroid preload pressure are very big; Moment of torsion in the time of certainly will increasing the wearing and tearing between valve seat and the spheroid and open spheroid; Influence the working life and the controlled conditions of ball valve, pretightening force hour sealing is difficult to again guarantee, this often just need the adjustment pretightening force guarantee its do not reveal and degree of tightness suitable; Waste time and energy, and be difficult to guarantee that the appropriate time goes to adjust.
Summary of the invention:
Goal of the invention of the present invention is difficult to guarantee and adjustment that the deficiency of ball valve wearing and tearing provides a kind of and can guarantee sealing load exactly to existing ball valve preload pressure, can make again that the ball valve wearing and tearing are little, the high long service life of reliability unload grey fixing ball valve.
Realize that above-mentioned purpose adopts following technological scheme: a kind of reliable sealing unload grey fixing ball valve, comprise valve body, spheroid, valve gap; Valve seat, cylinder, piston; The top that piston rod and ball valve drive unit, ball valve drive unit are positioned at valve body is connected with valve body, and piston, piston rod are positioned at cylinder; Described spheroid is positioned at valve body, and valve seat and valve gap are slidingly connected, and this valve seat is provided with O RunddichtringO and connected valve seat insert; Be evenly equipped with a plurality of cylinders and spring on the said valve gap, a plurality of springs, piston rod are pressed in respectively on the valve seat, are provided with the cushion ring between this valve seat and the cylinder head.
Adopt technique scheme; Compared with prior art, because the present invention is provided with cylinder, spring on valve gap, on valve seat, be provided with O-ring seals and valve seat insert; Between valve seat and cylinder, be provided with pad, a plurality of springs, piston rod are pressed on the valve seat respectively.This particular structural setting guarantees that ball valve sealing pressure is reliable, and spheroid and valve seat insert wearing and tearing are minimum, and then has overcome the defective of existing technology, has prolonged the working life of ball valve.
Description of drawings
Fig. 1 is a valve body structure schematic representation of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to view.
Among the figure, valve body 1, spheroid 2, valve seat 3, valve seat 4, O RunddichtringO 5, valve seat insert 6, cushion 7, spring 8, cylinder head 9, piston rod 10, piston 11, cylinder 12, inlet hole 13, air outlet hole 14, ball valve drive unit 15.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Present embodiment is the grey fixing ball valve of unloading of a kind of reliable sealing, is made up of valve body 1, spheroid 2, valve gap 3, valve seat 4, spring 8, cylinder head 9, piston rod 10, piston 11, cylinder 12, ball valve drive unit 15 etc.
Referring to Fig. 1, Fig. 2: spheroid 2 is contained in the valve body 1, and valve seat 4 is slidingly connected with valve gap 3.O RunddichtringO 5 is housed on the valve seat 4, and valve seat insert 6 is connected with valve seat 4 and forms sealing pair with spheroid 2.Valve gap 3 covers on valve body 1, is uniformly distributed with a plurality of cylinders 12 on the valve gap 3, and piston 11, piston rod 10 all are housed in a plurality of cylinders 12, and piston 11 is connected with piston rod 10 and cylinder head 9 is slidingly connected, and piston 11 is slidingly connected with cylinder 12.Be equipped with inlet hole 13, air outlet hole 14 on a plurality of cylinders 12.Be uniformly distributed with a plurality of springs 8 on the valve gap 3, a plurality of piston rods 10 all are pressed on the valve seat 4 with a plurality of springs 8, apply sealing load for valve seat 4.Cushion ring 7 is clipped between valve seat 4 and the cylinder head 9.Ball valve drive unit 15 adopts pneumatic, is installed in the top of valve body 1, is connected with spheroid 2 with support.
Working principle of the present invention and method for using:
Cylinder inlet hole 13 air inlet pressurizes during valve body 1 closed condition are pushed down valve seat 4 through piston 11 piston rods 10, and making between valve seat insert 6 and the spheroid 2 has enough sealing loads; Guarantee not have between spheroid 2 and the valve seat insert 6 and reveal, air outlet hole 14 links to each other with atmosphere all the time and filter screen is arranged, when opening spheroid 2; Cylinder inlet hole 13 is opened drive unit 15 interlocks with spheroid 2; At first inlet hole 13 releases (linking to each other) with atmosphere, ball valve drive unit 15 starts the rotating sphere unlatching then, after spheroid 2 unlatchings put in place; Again cylinder inlet hole 13 is calmed the anger, have enough pressure to guarantee that sealing pair does not have leakage between spheroid 2 and the valve seat insert 6.When spheroid 2 is closed, be still elder generation again, open ball valve drive unit 15 then cylinder inlet hole 13 releases (linking to each other) with atmosphere; Rotating sphere 2 is closed; Again by the 13 air inlet pressurizes of cylinder inlet hole, guarantee the pressure between spheroid 2 and the valve seat insert 6 after spheroid 2 is closed and put in place, make its sealing pair not have leakage.Spring 8 on the valve gap 3 mainly plays certain pretension and scrapes the ash effect, guarantees when the valve body opening and closing seamless.Cushion ring 7 is clipped between valve seat 4 and the cylinder head 9, plays to guarantee that valve seat has certain sliding space, guarantees that again lime-ash do not invade the space between valve seat 4 and the cylinder head 9.
More than disclosedly be merely specific embodiment of the present invention; Though the present invention discloses as above with preferred embodiment; But the present invention is not limited thereto, any those skilled in the art can think variation, in not breaking away from design philosophy of the present invention and scope; The present invention is carried out various changes and retouching, all should drop within protection scope of the present invention.
