Abstract
The utility model provides a vacuum ball valve with a fluorine liner and relates to the technical field of ball valves. The vacuum ball valve with the fluorine liner comprises a valve body, a ball body, a valve rod, a handle and the fluorine liner, wherein the ball body and the valve rod are connected with each other, and are installed in the valve body; the handle is connected with the valve rod; the fluorine liner is installed on a drift diameter in the valve body; and the vacuum ball valve is characterized in that: a spiral groove is arranged on the drift diameter of the valve body; a cylindrical net is arranged in the drift diameter of the valve body; the cylindrical net is made of 316L stainless steel, and has a thickness of 2mm; holes of the same size are arranged above the cylindrical net; the length of the cylindrical net is from a flange opening to a step of a valve seat; and the cylindrical net and the fluorine liner together are installed on the valve body. When the technical scheme is adopted, the valve body has a compact and reasonable structure; the space of an inner chamber of the valve body is minimized; the retention of media is reduced; the spiral groove increases the friction force between the lining material and the valve body; and the lining material cannot be moved and sucked out; moreover, as the net made of 316L stainless steel is arranged in the valve body, the lining material cannot be deformed in a vacuum system.
Description
Technical field
The utility model relates to the ball valve technical field.
Background technique
Vacuum lining fluorine ball valve (working pressure is lower than standard atmospheric pressure), its open-shut device is a spheroid, utilizes spheroid to realize the purpose of opening and closing around the axis half-twist of valve rod.Ball valve is mainly used in cut-out, distributes and changes the media flow direction on pipeline.
Q41F46 series lining fluorine ball valve is to control for the keying of various strong corrosive media pipelines to design, and is widely used in industries such as oil, chemical industry, dying, agricultural chemicals, relieving haperacidity system alkali, is one of optimal selection of present anticorrosion valve arrangement.Q41F46 series lining fluorine ball valve adopts fluoroplastics lining, housing adopts precision-investment casting, intensity height, outward appearance are bright and clean, and dividing with liquid contacting part all is fluoroplastic, so can be long-term used in corrosivity pipeline, the pipeline work of any concentration in-29 ℃～180 ℃ scopes.
Working principle:
The working principle of Q41F46-16C series lining fluorine ball valve makes valve unimpeded or inaccessible by rotatable handle, and the inboard all employings of handle and valve body fluoroplastic are made, and it is light that it has a switch, volume is little, and sealing is reliable, and is simple in structure, easy to maintenance, advantage such as using scope is wide.
Design feature:
The ball valve fundamental system is classified the Q41F46 type as, removes that to have the fluid resistance that general ball valve has little, and keying speed is fast, simple in structure outside, also have following advantage:
Adopt the ball valve of fluoroplastics lining nexine, have high chemical stability, go for any severe corrosive chemical mediator;
Adopt all-pass footpath, floating ball structure, valve can not have to leak in whole pressure range closes, and the pipeline pigging of the pipe-line system of being more convenient for and pipeline are safeguarded;
Open-shut device spheroid and valve rod casting (forging) are one, have stopped to impact the possibility in the pressure part because variation in pressure causes valve rod, have fundamentally guaranteed the safety in utilization in the engineering;
Compact structure is reasonable, and body cavity space minimum has reduced the medium delay, and in addition, special mould pressing process makes the sealing surface consistency good, and herringbone ring-shaped P TFE filler combination makes valve reach zero leakage in addition;
For the advantage that makes lining fluorine ball valve can show especially more, it is applied to system in the vacuum, when still common lining fluorine ball valve is used for vacuum system,, will not satisfy requirement because the restriction of the serviceability temperature of fluorine-lining valve door adds self characteristics.
The fluorine-lining valve door in vacuum system, wadding under atmospheric pressure with high temperature acting in conjunction under can displacement, distortion can be sucked out fully under the situation about having, thereby make valve lose due effect.
The model utility content
The purpose of this utility model is: design a kind of vacuum lining fluorine ball valve, to overcome deficiency of the prior art, can normally use under vacuum condition.
The technical solution adopted in the utility model is: a kind of vacuum lining fluorine ball valve, comprise valve body, spheroid, valve rod, handle and lining fluorine, spheroid links to each other with valve rod and is installed in the valve body by valve rod, handle is connected with valve rod, the lining fluorine is installed on the interior latus rectum of valve body, it is characterized in that: described valve body latus rectum is provided with spiral chute, is provided with coghill net in the described valve body latus rectum.
The material of described coghill net is the 316L stainless steel.
The thickness of described coghill net is 1-4mm, is provided with the identical hole of size above, and the length of described coghill net is to the valve seat step from flange mouth.
Described coghill net together is installed on the valve body with the lining fluorine.
Compared with prior art, advantage of the present utility model and beneficial effect are:
1, adopt technical solutions of the utility model, compact structure is reasonable, and body cavity space minimum has reduced the medium delay;
2, adopt technical solutions of the utility model, spiral chute is opened on the latus rectum surface, wadding is when being subjected to transverse force, and spiral chute has increased the frictional force of wadding and valve body, can not make wadding move and be sucked out;
3, adopting technical solutions of the utility model, is the stainless net of 316L owing to increased material at valve interior surface, and wadding can not be out of shape in vacuum system.
