Abstract

The invention discloses a high-sealing-performance corrosion-resistant fully-padded stop valve. The high-sealing-performance corrosion-resistant fully-padded stop valve comprises a valve body, a valve cover, a valve clack and a valve rod, wherein the valve body, the valve cover, the valve clack and the valve rod are coated with corrosion-resistant materials respectively. The end conical surface of the valve clack, an inner cavity of the valve body and the surface of the valve rod are respectively provided with evenly-distributed dovetail grooves, and the dovetail grooves are filled with the corrosion-resistant materials so that the corrosion-resistant materials can be integrated with a metallic matrix, wherein the corrosion-resistant materials are teflon composite layers. A plurality of inner holes are evenly formed in the plane of one side, away from the valve cover, of the end of the valve clack, and the opening end of each inner hole is chamfered. The valve clack and the valve rod are integrally formed through forging. The valve cover is in tongue-and-groove type connection with the valve body in a sealed mode. The high-sealing-performance corrosion-resistant fully-padded stop valve is reasonable in sealing structure, good in sealing performance, safe and reliable.

Description

The corrosion-resistant full-lining stop valve of high leak tightness
Technical field
The present invention relates to a kind of valve of carrying for deep-etching materials such as wet chlorine, particularly a kind of not need to stop be the wet chlorine special valve of replaceable valve packing.
Background technique
At present, known common valve is comprised of critical pieces such as valve body, valve gap, flap, valve rod, nuts, and each component materials is generally not corrosion-resistant.This type of common valve, once for delivery of the deep-etchings such as chlor-alkali, poisonous medium, leaks with the as easy as rolling off a log corrosion of medium contact part.Thereby harm surrounding enviroment and personal safety.
In recent years, the specific (special) requirements of carrying according to poisonous, easy leaking medium, some defects of using for existing valve, have announced many about preventing the technological scheme of the valve special for chlorine of chlorine leakage now in technology.But in actual applications, because these technological schemes still adopt plane sealing structure, in fed sheet of a media, contain and under the special operation conditions such as granule foreign, more easily damage sealing by pressure and close, cause seal failure and leak.
Summary of the invention
In order to overcome the deficiency that must stop when existing wet chlorine valve is changed filler, the invention provides the corrosion-resistant full-lining stop valve of a kind of high leak tightness, this valve seal is good, safe and reliable.
The present invention is achieved through the following technical solutions technical goal.
The corrosion-resistant full-lining stop valve of high leak tightness, comprise the valve body, valve gap, flap, the valve rod that are covered with resistant material, its improvements are: the described flap end conical surface, body cavity, stem surface are provided with equally distributed dovetail groove, thereby resistant material is filled in described dovetail groove and is integrally formed with metallic matrix, and described resistant material is teflon composite bed.
As the present invention, further improve described dovetail groove bottom land width≤2.5mm, width of rebate≤2.5mm, groove depth≤2mm.
As further improvement of the present invention, described flap end is provided with several equally distributed endoporus away from valve gap one side plane, the mouth chamfer of described endoporus; Described flap and valve rod are that solid forging forms; Described valve gap and valve body tenon-slot type are tightly connected.
The present invention compared with prior art, there is following good effect: the general direct covering one deck resistant material of common its flap of chlor-alkali valve and stem surface, but along with the motion of flap, valve rod, cover that anti-corrosion layer above it is easy to become flexible, aliquation, bulge, directly affect sealing effect.The present invention is provided with a plurality of equally distributed endoporus at flap end plane, at the mouth of endoporus, holds 50 °～55 ° angles, at the flap end conical surface, body cavity, stem surface arranges equally distributed dovetail groove, control dovetail groove bottom land width≤2.5mm, width of rebate≤2.5mm, groove depth≤2mm, again resistant material is filled in these holes and groove in, neither affect flap, the bulk strength of valve rod, can make again resistant material completely and metallic matrix be integrally formed, guarantee flap, not loosening during valve rod work, aliquation, bulge, that can play is corrosion-resistant, the effect of antiscour, overall tightness is also better, valve body material adopts corrosion-resisting alloy steel to make according to the specific (special) requirements of chemical industry for making chlorine and alkali industrial and mineral, solve often the bore a hole difficult problem of chlorine leakage of common valve housing.
