Description

Wear-resisting acidproof special fixing ball valve

Technical field

The utility model relates to a kind of valve, particularly the wear-resisting acidproof special fixing ball valve of one, and two ball valves are that the two ball of integral type is arranged side by side structure.

Background technique

Ceramic ball valve is all is structural ceramic material with the part of medium contact, and its chemical stability and extreme hardness, be only second to diamond, is widely used in power plant's dry ash system, desulphurization system and mine washup pipeline.Ceramic ball valve is used at present in desulphurization system pipe-line system, reach dual fail-safe, two cut-out, two blocking, double playing function, two ball valves are at least needed directly to be installed in series, respectively in order to control the keying of pipeline, shunting, regulate, need the flow center line debugging two ball valves when mounted simultaneously, not only increase installation difficulty, and it is very loaded down with trivial details in operation, controllers is difficult to fast, accurately pipeline is opened and closed, the operations such as adjustment, inconvenience is brought to user, and when pipeline needs to cut off, need to carry out cut-out action to two ball valves or multiple valve simultaneously, as cut off hyperpraxia, cause ceramic ball valve impaired too fast, lower valve working life, economic loss is brought to user.

Summary of the invention

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of wear-resisting acidproof special fixing ball valve, is made up of end cap, pre-ceramic body, lining tetrafluoro, spring, valve seat, spheroid, O type circle, middle body pottery, base, middle valve seat, metal wound gasket, axle sleeve, upper valve rod, valve gap, filler.

The utility model solves the technological scheme that its technical problem adopts: end cap is two flange conjuncted structures, end cap outward appearance sectional drawing is " work " word shape, the outward flange diameter of end cap is greater than inner flange diameter, end cap inwall sectional drawing is " recessed " word shape, end cap inwall intermediate portion is provided with annular boss, cover ceramic intermediate portion and be provided with ring-shaped step, end cap annular boss connects into sealing configuration with the ceramic ring-shaped step of lid, lid pottery embeds in end cap completely, cover ceramic outer end and end cap collar extension immediately, between lid pottery and end cap, lining tetrafluoro is set, the sectional drawing of lid pottery is " convex " word shape, lid pottery is circular hollow structure, body pottery in the arrangement of valve pocket inner peripheral wall, middle body pottery is circular hollow structure, the spheroid of two stupaliths is provided with in middle body pottery, the size of two spheroids is the same, arrange middle valve seat in the middle of two spheroids, middle valve seat is large, middle little " dumbbell " shapes in upper and lower two ends, all arranges valve seat construction in the two ends up and down of middle valve seat, valve seat construction forms sealing under the action of the spring, and overall valve forms the two ball of integral type and is arranged side by side structure.

The utility model beneficial effect: can use by alternating movement two spheroids, the life-span is longer, uses pipeline and reaches dual fail-safe, two cutting action, regulating flow quantity, two blocking, doublely to put, pacify congruous function.

Accompanying drawing explanation

Fig. 1 is the utility model overall structure schematic diagram;

In figure, 1, end cap, 2, lid pottery, 3, lining tetrafluoro, 4, spring, 5, front valve seat, 6, spheroid 7, O type circle, 8, middle body pottery, 9, rear base, 10, middle valve seat, 11, metal wound gasket, 12, axle sleeve, 13, upper valve rod, 14, valve gap, 15, filler.

Embodiment

As shown in drawings, whole valve is made up of in the middle part of valve front portion, valve and valve rear portion, valve front portion comprises end cap 1, pre-ceramic body 2, lining tetrafluoro 3, spring 4, front valve seat 5, end cap 1 is two flange conjuncted structures, and end cap 1 outward appearance sectional drawing is " work " word shape, and the outward flange diameter of end cap 1 is greater than inner flange diameter, end cap 1 inwall sectional drawing is " recessed " word shape, inner flange is connected with middle valve portion, and inner flange and joint, middle valve portion are provided with metal wound gasket 11, and outward flange and pipeline carry out Flange joint, end cap 1 inwall intermediate portion is provided with annular boss, cover ceramic 2 intermediate portions and be provided with ring-shaped step, end cap annular boss connects into sealing configuration with the ceramic ring-shaped step of lid, lid pottery embeds in end cap completely, cover ceramic outer end and end cap collar extension immediately, between lid pottery and end cap, lining tetrafluoro 3 is set, guarantee sealing, the sectional drawing of lid pottery 2 is " convex " word shape, lid pottery 2 is circular hollow structure, cover ceramic 2 inner ends and front valve seat 5 is installed, cover ceramic 2 inner ends and front valve seat 5 is provided with spring 4, front valve seat 5 carries out mobile working and contacts to be formed with spheroid 6 and seal under spring 4 acts on.

Spheroid 6, O type circle 7, middle body pottery 8, middle valve seat 10, metal wound gasket 11, axle sleeve 12, upper valve rod 13, gland 14, filler 15 is comprised in the middle part of valve, joint in the middle part of valve front portion, valve and between valve rear portion all arranges metal wound gasket 11, fix with bolt, metal wound gasket 11 guarantees seal action; Body pottery 8 in the arrangement of valve pocket inner peripheral wall, middle body pottery 8 is circular hollow structure, the spheroid 6 of two stupaliths is provided with in middle body pottery 8, the size of two spheroids 6 is the same, in the middle of two spheroids 6, middle valve seat 10 is set, middle valve seat 10 is large, middle little " dumbbell " shapes in upper and lower two ends, and all arrange valve seat construction in the two ends up and down of middle valve seat 10, valve seat construction forms sealing under spring 4 acts on; Two spheroids 6 are fixed on two bases 9 below, and base 9 and lower valve rod make integrative-structure, and base 9 is installed in valve pocket from valve bottom outlet, two bases 9 are equipped with two road sealing grooves, be equipped with O type circle 7 in two road sealing grooves, guarantee that base 9 seals, and be screwed; Two spheroids 6 all have connection upper valve rod 13 above, and upper valve rod 13 is provided with the anti-boss flying structure, valve rod boss is settled filler 12 and two road O type circles 7, forms seal action, above valve gap 14 is fixing, valve gap 14 arrange actuating device.With a spheroid, pipeline is cut off, the only just action after the valve base sealing component failures of this spheroid of another spheroid, also can make the longer service life of this product by alternating movement two spheroids, pipeline is used and reaches dual fail-safe, two cut-out, doublely put effect.
