Abstract
The utility model relates to an anti-washout top-mounted type V-shaped regulating valve for the coal chemical industry. The anti-washout top-mounted type V-shaped regulating valve comprises a main shaft (1), a valve body (3) and a valve element (2), and is characterized in that the upper end of the valve element (2) is connected with the main shaft (1), the lower end of the valve element (2) is connected with an auxiliary shaft which is arranged on the valve body (3), the valve element (2) is provided with a V-shaped window, and a spherical surface is arranged at the top end of the V-shaped window. It is proved on trail that after adoption of the regulating valve, the washout problem of baring powder coal on a valve cavity and the valve element under the work condition of the coal chemical industry is solved, the service life of the regulating valve is effectively prolonged, and the requirement for localization of the regulating valve for the coal chemical industry is met.
Description
Technical field
The utility model relates to a kind of Coal Chemical Industry with filling formula V-type modulating valve on protection against erosion.
Background technique
Use valve field in Coal Chemical Industry, Coal Chemical Industry is selected modulating valve, adopts Durchflub-Regelventil and eccentric rotary regulating valve more, and due to the runner design of Durchflub-Regelventil S type, coal dust is very serious to washing away of valve pocket, and this is also current problem in a helpless situation.Core shift rotating regulation valve, within the scope of little aperture, cannot overcome coal dust to the washing away of spool due to gap stream, also cannot overcome.Along with Coal Chemical Industry operating mode is more and more higher to the requirement of modulating valve, existing structure cannot meet the demand of Coal Chemical Industry bad working environments,
Model utility content
The purpose of this utility model is to provide a kind of Coal Chemical Industry with filling formula V-type modulating valve on protection against erosion, can in possessing flow regulating function, have stronger erosion resistibility.
A kind of Coal Chemical Industry is with filling formula V-type modulating valve on protection against erosion, comprise main shaft, valve body and spool, its specialization is: the upper end of described spool is connected with main shaft and its lower end is connected with countershaft, this countershaft is arranged on described valve body, on this spool, have V-type window, and the top of this V-type window is spherical surface.
Wherein on the internal surface at the other valve outlet place of spool, be provided with abrasion resistance alloy lining, abrasion resistance alloy lining material is YG11 alloy, and alloy thickness range is at 5-10mm.
Wherein abrasion resistance alloy lining is circular tube shaped, and this abrasion resistance alloy lining is provided with inclined-plane near one end inwall of spool.
Wherein spool adopts HG11 alloy.
Through probationary certificate, adopt after modulating valve of the present utility model, solve the wash away problem of coal dust to valve pocket and spool under Coal Chemical Industry operating mode, effectively extend the working life of modulating valve, also solve the demand of Coal Chemical Industry modulating valve valve production domesticization simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of spool 2 in the utility model;
Accompanying drawing 3 is the structural representation of spool 2 in the utility model;
Accompanying drawing 4 is the sectional view of spool 2 in the utility model;
The C-C sectional view that accompanying drawing 5 is Fig. 4.
Embodiment
As shown in Fig. 1,2,3,4,5, the utility model is that a kind of Coal Chemical Industry is with filling formula V-type modulating valve on protection against erosion, comprise main shaft 1, valve body 3, valve seat and spool 2, the upper end of described spool 2 is connected with main shaft 1 and its lower end is connected with countershaft, this countershaft is arranged on described valve body 3, on this spool 2, have V-type window, and the top of this V-type window is spherical surface.
Wherein on the internal surface in other valve body 3 outlet ports of spool 2, be provided with abrasion resistance alloy lining, abrasion resistance alloy lining is YG11 alloy, and alloy thickness range is at 5-10mm.This abrasion resistance alloy lining is circular tube shaped, and this abrasion resistance alloy lining is provided with inclined-plane near one end inwall of spool 2.Spool 2 adopts HG11 alloy in addition.
Working principle of the present utility model and using method are: drive ball core (spool 2) to rotate when main shaft 1 is activated when device drives, ball core is in opening procedure, between V-type window and valve seat, form the runner of different area, thereby realize adjusting and the antiscour function of flow, valve seat to ball core has self-cleaning function, in the time that ball core window turns over 90 °, just form sealing effect with valve seat.
Claims (4)
1. a Coal Chemical Industry is with filling formula V-type modulating valve on protection against erosion, comprise main shaft (1), valve body (3) and spool (2), it is characterized in that: the upper end of described spool (2) is connected with main shaft (1) and its lower end is connected with countershaft, this countershaft is arranged on described valve body (3), on this spool (2), have V-type window, and the top of this V-type window is spherical surface.
2. Coal Chemical Industry as claimed in claim 1 is with filling formula V-type modulating valve on protection against erosion, it is characterized in that: wherein on the internal surface in other valve body (3) outlet port of spool (2), be provided with abrasion resistance alloy lining, abrasion resistance alloy lining material is YG11 alloy, and alloy thickness range is at 5-10mm.
