Description

Top-mounted corrugated pipe ball valve

Technical Field

The utility model relates to the technical field of valves, especially, relate to upper assembling type bellows ball valve.

Background

The ball valve uses a ball body with a circular channel as an opening and closing member, the ball body rotates along with a valve rod to realize the opening and closing of the valve, the opening and closing member of the ball valve is a ball body with a hole and rotates around an axis vertical to the channel, thereby achieving the purpose of opening and closing the channel, and the ball valve is mainly used for opening and closing pipelines and equipment media.

Ball valves are also used in chlor-alkali plants, of the top-loading type, for conveying liquid chlorine or chlorine and other media, which can undergo substitution and addition reactions with organic and inorganic substances to produce various chlorides, mainly for the production of plastics (such as PVP), synthetic fibers, dyes, pesticides, disinfectants, bleach solvents and various chlorides.

At present, use ball valve atmosphere sealing layer to adopt the packing to seal in the chlor-alkali factory, the packing is sealed to adopt V-arrangement tetrafluoro gasket, V-arrangement tetrafluoro gasket is components of a whole that can function independently column structure, cause the medium to leak outward very easily, because, meet the danger that the highlight probably can explode when mixing the hydrogen that the volume fraction is more than 5% in the chlorine, have latent potential safety hazard, and chlorine has the toxicity, mainly invade the human body and dissolve in the moisture that the mucous membrane contains through the respiratory track, can cause the harm to the upper respiratory track mucous membrane, harm to the human body is great, influence the use of ball valve in the chlor-alkali factory, exist not enoughly.

To sum up, to the defect that exists among the prior art, the utility model provides a facial make-up bellows ball valve to solve prior art not enough.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a top-mounted bellows ball valve does not influence the switching of valve, and sealing filler adopts bellows seal, the effectual risk that has reduced the medium and leaked outward, and practicality is excellent.

The utility model discloses a solve the technical scheme that its technical problem adopted and be:

the facial make-up bellows ball valve includes: the valve body, the inside setting of valve body is the spheroid of opening and close piece, and the spheroid top is provided with the valve rod, and the valve rod outwards extends to the valve body outside, and the spheroid top is fixed with the gear, and the valve rod is provided with the rack toothing on the spheroid direction, and the contact site of valve rod and valve body is provided with the atmosphere sealing layer, and the packing of atmosphere sealing layer adopts the bellows.

Furthermore, the ball body and the gear are fixedly connected in an integrated or split manner.

Furthermore, the corrugated pipe is made of C-276 hastelloy.

Furthermore, the end face of the valve rod is provided with a rotating handle.

The utility model has the advantages that:

to sum up, the utility model has the advantages of simple structure, convenient to use satisfies the ball valve in the user demand of chlor-alkali factory, and easy operation is convenient for carry out the switching to the ball valve, and sealing packing adopts bellows seal, ensures that the atmosphere sealing layer between valve rod and the valve body packs tightly, and the effectual risk that leaks outside the medium that has reduced has avoided chlorine in the ball valve to leak outside, causes the injury to the human body, and practicality is excellent.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the drawings and the specific embodiments.

As shown in fig. 1, the top-loading type bellows ball valve includes: the valve comprises a valve body 100, a ball 110 serving as an opening and closing element is arranged inside the valve body 100, a valve rod 130 is arranged above the ball 110, the valve rod 130 extends outwards to the outside of the valve body 100, a gear 120 is fixed above the ball 110, a rack 140 which is meshed with the gear 120 is arranged on the valve rod 130 in the direction towards the ball, an atmosphere sealing layer is arranged at the contact part of the valve rod 130 and the valve body 100, and a corrugated pipe 150 is adopted as the filling material of the atmosphere sealing layer.

In addition, the sphere 110 and the gear 120 are fixedly connected by integral molding or splitting, the corrugated tube 150 is made of C-276 Hastelloy, and the end surface of the valve rod 130 is provided with a rotary handle 160.

The utility model discloses the spheroid is as opening and closing, be provided with the transfer passage through liquid chlorine or chlorine in the spheroid, the spheroid is rotatory around the axis of perpendicular to valve body passageway, thereby reach the purpose of opening and close the passageway, spheroidal top is fixed with the gear, the rack toothing gear that sets up on the valve rod, the valve rod extends to the outside of valve body, be provided with the rotation handle on the valve rod, the operation rotates the handle, the gear meshes the rotation on the rack, gear revolve drives the spheroid and rotates, in order to reach the purpose that the control spheroid opened and close, contact site between valve rod and the valve body is provided with the atmosphere sealing layer, the packing of atmosphere sealing layer adopts the bellows, because the bellows is continuous column structure, can effectually seal up the inside chlorine or the liquid chlorine of valve body, reduce leakage danger.

The utility model discloses have the user demand who satisfies the ball valve in the chlor-alkali factory, easy operation is convenient for carry out the switching to the ball valve, and sealing packing adopts bellows seal, ensures that the atmosphere sealing layer between valve rod and the valve body packs tightly, the effectual risk that leaks outside the medium that has reduced leaks has avoided chlorine in the ball valve to leak outside, causes the injury to the human body, and the practicality is excellent.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to let the technical personnel in the field understand the contents of the present invention and implement the present invention, and the protection scope of the present invention can not be limited thereby, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
