Abstract
The utility model discloses a ball valve comprising a valve body, wherein a spheroidal valve flap is arranged in the valve body and is connected with a valve rod; the valve rod extends out of the cavity of the valve body; a valve cap matched with the valve rod is arranged at the top of the valve body; a valve seat in interference fit with the valve flap is arranged in the valve body; a fluoroplastic lining is arranged on the inner wall of the valve body; a plurality of lining fixing grooves are formed in the inner wall of the valve body; a fluoroplastic lining is arranged on the outer wall of the valve flap. As the fluoroplastic linings are additionally arranged on the inner wall and the outer wall of the valve flap, the corrosion on the inner wall of the valve body and the valve flap can be prevented effectively, and the service life of the ball valve is prolonged; a sealing material and a plurality of overlapped circular arc-shaped sealing rings are filled in the matched gap among the valve cap, the valve body and the valve flap, so that the leak-proofness of the ball valve in a high-pressure environment is improved.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of corrosion resistant ball valve.
Background technique
Ball valve is mainly used to block and the ducted medium of conducting, and because its circulation area after the ball valve unlatching is consistent with the endoporus of pipeline, so resistance is very little, the essentially no pressure loss, so be widely used in oil, chemical industry, medical treatment, metallurgy, mine, the many fields of food etc.If coordinate with the adjustment type final controlling element, can also carry out flow to ducted medium, the adjusting of pressure.
The disclosed ball valve of prior art, comprise valve body, flap, valve seat, valve rod and valve gap, and wherein, spherical flap and valve seat interference fit form sealing.Valve body adopts the ferrous metal materials such as WCB usually, and flap adopts stainless steel and relevant steel matter usually.Valve seat adopts the soft sealing materials such as teflon or graphite.The ferrous materials decay resistance is poor, and the soft sealing material strength ratio is lower.When ducted medium has corrosivity, valve interior wall and the direct contact medium of flap meeting due to ball valve, easily be corroded, and directly has influence on the working life of ball valve.
In addition, the disclosed ball valve of prior art airtight performance in hyperbaric environment is not good.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of ball valve, to reach the corrosion phenomenon that prevents valve interior wall and flap, increases the service life, and promotes the purpose of seal in hyperbaric environment.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of ball valve, comprise valve body, be provided with spherical flap in described valve body, described flap is connected with valve rod, and described valve rod extend out to the cavity outside of described valve body, and described valve body top is provided with the valve gap coordinated with described valve rod, be provided with the valve seat with described flap interference fit in described valve body, described valve interior wall is provided with fluoroplastics lining, and described valve interior wall offers several lining fixed grooves, and described flap outer wall also is provided with fluoroplastics lining.
Preferably, be filled with sealing material and several pieces ring arcuation seal rings overlaped in the cooperation space between described valve gap and described valve body, described flap.
Preferably, described valve stem tip screw is fixedly connected with handle.
Pass through technique scheme, a kind of ball valve that the utility model provides is by increasing fluoroplastics lining at valve interior wall and flap outer wall, can effectively prevent the corrosion phenomenon of valve interior wall and flap, extend working life of the present utility model, be filled with sealing material and several pieces ring arcuation seal rings overlaped in cooperation space between valve gap and valve body, flap three, promoted the seal of the utility model in hyperbaric environment.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described.
The structural representation that Fig. 1 is the disclosed a kind of ball valve of the utility model embodiment.
The represented corresponding part title of numeral in figure:
1, valve body 2, flap 3, valve rod 4, valve gap 5, valve seat 6, lining
7, fixed groove 8, sealing material 9, seal ring
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
According to Fig. 1, the utility model provides a kind of ball valve, comprise valve body 1, be provided with spherical flap 2 in valve body 1, flap 2 is connected with valve rod 3, valve rod 3 extend out to the cavity outside of valve body 1, valve body 1 top is provided with the valve gap 4 coordinated with valve rod 3, be provided with the valve seat 5 with flap 2 interference fit in valve body 1, valve body 1 inwall is provided with high temperature resistant and corrosion resistant fluoroplastics lining 6, valve body 1 inwall offers several lining fixed grooves 7, lining 6 is embedded in lining fixed groove 7, with valve body 1 inwall, be combined more firmly, flap 2 outer walls also are provided with fluoroplastics lining 6, wherein, valve gap 4 and valve body 1, be filled with sealing material 8 and several pieces ring arcuation seal rings 9 that overlap in cooperation space between flap 2, valve rod 3 top screws are fixedly connected with handle, valve seat 5 is arranged between flap 2 and fluoroplastics lining 6.
9 combinations of the overlapping thin type ring arcuation of sealing material 8 and multi-disc seal ring, utilize the elasticity between seal ring 9 ring arcuations, avoids the variation of Yin Wendu and make valve contingency occur, and reduce wearing and tearing, improved sealability.
Changed when flap 2 or valve rod 3 damage for convenient, and reduced expenses, between flap 2 and valve rod 3, adopt and removably connect.
A kind of ball valve that the utility model provides is by increasing fluoroplastics lining 6 at valve body 1 inwall and flap 2 outer walls, can effectively prevent the corrosion phenomenon of valve body 1 inwall and flap 2, extend working life of the present utility model, be filled with sealing material 8 and several pieces ring arcuation seal rings 9 overlaped in cooperation space between valve gap 4 and valve body 1, flap 2 threes, promoted the seal of the utility model in hyperbaric environment.
To disclosed a kind of ball valve embodiment's above-mentioned explanation, make professional and technical personnel in the field can realize or use the utility model.Multiple modification to these embodiments will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
