Abstract
The invention relates to a corrosion-resistant, wear-resistant camflex valve, which comprises a valve body (5) and a spool (3) in the valve body (5), both ends of the spool (3) are respectively connected with a main shaft (1) and an auxiliary shaft (4), a valve seat (2) which can cooperate with the spool (3) to open and close a flow passage is arranged in a medium inlet of the valve body (5), and the corrosion-resistant, wear-resistant camflex valve is characterized in that a hard alloy bushing (7) is mounted on the inner surface of the valve body (5). A trial proves that the corrosion resistance and erosion resistance of the valve body (5) and the spool (3) of the camflex valve are remarkably enhanced, the service life of the whole valve is prolonged from original forty to fifty days to half a year, and therefore production efficiency and economic benefit are greatly increased for users.
Description
Technical field
The present invention relates to the caimflex valve that a kind of anticorrosive wear-resistant decreases.
Background technique
In common application, original caimflex valve is simple in structure, applied range, good stability.Along with the rise of Coal Chemical Industry industry, original caimflex valve (referring to Fig. 1) can not adapt to its abominable operating mode, under the Coal Chemical Industry operating mode of harshness; The flap of valve body and spool has formed big quilt and has pressed the chamber; Granular high temperature, high-pressure medium form serious eddy current at this, thereby valve body and spool are carried out strong impact and wearing and tearing, because the deep-etching of medium and strong abrasiveness; The spool that common stainless steel body and plasma surfacing are handled the washing away of medium of having unable to born; Make the lost of life of whole deck valve, the life cycle of a deck valve has only four, 50 days, has had a strong impact on normally carrying out of work on the spot.
Summary of the invention
The purpose of this invention is to provide a kind of anticorrosive, anti-washing away, and the caimflex valve of a kind of anticorrosive wear-resistant damage of long service life.
The caimflex valve that a kind of anticorrosive wear-resistant decreases; Comprise the spool in valve body and the valve body; The two ends of spool are connected with countershaft with main shaft respectively; Thereby the medium inlet in valve body is provided with the valve seat that cooperates unlatching with spool, closes runner, and its specialization is: the cemented carbide lining is installed on said valve interior surface.
Wherein at valve outlet one gland is installed, the inwall of this gland and adjacent valve interior wall form step-like, reduce the medium circulating resistance thereby on the other cemented carbide lining of this gland, be provided with the inclined-plane or the curved surface that cooperate with this step.
Wherein on spool, be inlaid with hard alloy layer with the corresponding wash surface of valve seat.
Wherein the cemented carbide lining is made up of two cemented carbide sleeve pipes.
Wherein countershaft is installed on the valve body, and an end of this countershaft is connected with spool, and the other end of this countershaft stretches out outside the valve body.
Wherein the inner surface portion outside the valve body upper inlet is sentenced is divided into smooth pipe shape.
Wherein cemented carbide is a Tungsten carbite.
Thick 8～the 10mm of cemented carbide lining wherein.
Through probationary certificate, the valve body of caimflex valve of the present invention, spool is anticorrosive and performance of flushing significantly improves, and extended to half a year by original four, 50 days the working life of whole deck valve, improved user's manufacturing efficiency and economic benefit to a great extent.
Description of drawings
Accompanying drawing 1 is the structural representation of background technique of the present invention;
Accompanying drawing 2 is a structural representation of the present invention.
Embodiment
As shown in Figure 2; The caimflex valve that a kind of anticorrosive wear-resistant decreases; Comprise the spool 3 in valve body 5 and the valve body 5; The two ends of spool 3 are connected with countershaft 4 with main shaft 1 respectively, thereby the medium inlet in valve body 5 is provided with spool 3 valve seat 2 that cooperates unlatching, closes runner, wherein on valve body 5 internal surfaces, cemented carbide lining 7 are installed.
In valve body 5 outlets one gland 6 is installed in addition; Adopt the wound gasket sealing between gland 6 and the valve body 5; Prevent to leak outside; The inwall of this gland 6 and adjacent valve body 5 inwalls form step-like, reduce the medium circulating resistance thereby on the cemented carbide lining 7 on these gland 6 sides, be provided with the inclined-plane or the curved surface that cooperate with this step.Clearly, such design is particularly suitable for the situation that cemented carbide lining 7 is made up of two cemented carbide sleeve pipes.
As shown in Figure 2, countershaft 4 is installed on the valve body 5, and an end of this countershaft 4 is connected with spool 3, and the other end of this countershaft 4 stretches out outside the valve body 5.
On spool 3, be inlaid with hard alloy layer with valve seat 2 corresponding wash surfaces, the inner surface portion (being intermediate portion among Fig. 2) beyond valve body 5 inlets is smooth pipe shape,
Cemented carbide specifically adopts Tungsten carbite, also can select other cemented carbide that under the Coal Chemical Industry operating mode, has the high corrosion resistance ability for use, and design cemented carbide lining 7 thick 8～10mm.
The valve body 5 of caimflex valve of the present invention adopts the double-body bikes design, and inner chamber is straight, smooth piping design, is convenient to the process treating such as spraying, built-up welding of trim, or cemented carbide lining 7 directly is installed, and has improved work efficiency and quality of processing.
As shown in Figure 2, be nested with two cemented carbide sleeve pipes at level and smooth valve body 5, thereby improved resistance to wearing and corrosion resistance of whole valve body 5.Countershaft 4 major parts of spool 3 place the outside of valve body 5, have dwindled the inner cavity size of valve body 5, and inner-cavity structure is oversimplified, and improve the negotiability of medium, are easier to the nested of cemented carbide and protection countershaft 4.The wash surface of spool 3 is attend tungsten carbide button, has improved wear-resisting, corrosion-resistant and whole sealability.
