Abstract
The invention discloses a ball valve which comprises a valve body. A spherical valve flap is arranged in the valve body and 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. Due to the fact that the fluoroplastic linings are additionally arranged on the inner wall and the outer wall of the valve flap, corrosion of 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. The matching gap among the valve cap, the valve body and the valve flap is filled with sealing material and a plurality of overlapped annular arc-shaped sealing rings, so that the airtightness of the ball valve in a high-pressure environment is improved.
Description
Technical field
The present invention relates to a kind of valve, particularly the corrosion resistant ball valve of one.
Background technique
Ball valve is mainly used to the ducted medium of Trimmed sums conducting, and because after ball valve unlatching, its circulation area is consistent with the endoporus of pipeline, therefore 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 adjustment type final controlling element, flow can also be carried out to ducted medium, the adjustment of pressure.
Ball valve disclosed in prior art, comprises valve body, flap, valve seat, valve rod and valve gap, and wherein, spherical flap and valve seat interference fit are formed and seal.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 material such as teflon or graphite.Ferrous materials decay resistance is poor, and soft sealing material strength ratio is lower.When ducted medium has corrosivity, because the valve interior wall of ball valve and flap can direct contact mediums, be easily corroded, directly have influence on the working life of ball valve.
In addition, the airtight performance in hyperbaric environment of the ball valve disclosed in prior art is not good.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of ball valve, to reach the corrosion phenomenon preventing valve interior wall and flap, increasing the service life, and promote the object of seal in hyperbaric environment.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of ball valve, comprise valve body, spherical flap is provided with in described valve body, described flap is connected with valve rod, and described valve rod extend out to the containment portion of described valve body, and described body top is provided with the valve gap coordinated with described valve rod, the valve seat with described flap interference fit is provided with in described valve body, described valve interior wall is provided with fluoroplastics lining, and described valve interior wall offers several lining fixed groove, and described flap outer wall is also provided with fluoroplastics lining.
Preferably, sealing material and several pieces ring arcuation seal rings overlaped is filled with 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 provided by the invention is by increasing fluoroplastics lining at valve interior wall and flap outer wall, effectively can prevent the corrosion phenomenon of valve interior wall and flap, extend working life of the present invention, be filled with sealing material and several pieces ring arcuation seal rings overlaped in cooperation space between valve gap and valve body, flap three, improve the seal of the present invention in hyperbaric environment.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
Fig. 1 is the structural representation of a kind of ball valve disclosed in the embodiment of the present invention.
Corresponding part title in figure represented by numeral:
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 embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described.
According to Fig. 1, the invention provides a kind of ball valve, comprise valve body 1, spherical flap 2 is provided with in valve body 1, flap 2 is connected with valve rod 3, valve rod 3 extend out to the containment portion of valve body 1, valve body 1 top is provided with the valve gap 4 coordinated with valve rod 3, the valve seat 5 with flap 2 interference fit is provided with 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 groove 7, lining 6 is embedded in lining fixed groove 7, be combined more firm with valve body 1 inwall, flap 2 outer wall is also provided with fluoroplastics lining 6, wherein, valve gap 4 and valve body 1, sealing material 8 and several pieces ring arcuation seal rings 9 overlaped are filled with in cooperation space between flap 2, valve rod 3 top screw is fixedly connected with handle, valve seat 5 is arranged between flap 2 and fluoroplastics lining 6.
It is the lining 6 of material that valve body 1 inwall and flap 2 outer wall are lined with fluoroplastic, utilizes the plasticity of fluoroplastic, does shell or do internal control with iron and steel, by fluoroplastics lining in valve body 1 and lining mould in flap 2 surface.Be used for isolated die metal with this to contact with the direct of strong corrosive medium.
Sealing material 8 and multi-disc overlapping thin type ring arcuation seal ring 9 combine, and utilize the elasticity between seal ring 9 ring arcuation, avoid the change of Yin Wendu and make valve occur contingency, and reduce wearing and tearing, improve sealability.
Conveniently change when flap 2 or valve rod 3 damage, and reduce expenses, adopt between flap 2 and valve rod 3 and removably connect.
A kind of ball valve provided by the invention is by increasing fluoroplastics lining 6 at valve body 1 inwall and flap 2 outer wall, effectively can prevent the corrosion phenomenon of valve body 1 inwall and flap 2, extend working life of the present invention, 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 three, improve the seal of the present invention in hyperbaric environment.
To the above-mentioned explanation of disclosed a kind of ball valve embodiment, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention 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.
