Abstract
An abrasion-resistant high-pressure valve comprises a valve body. A cavity is formed in the valve body. A sealing base is arranged in the valve body. One side of the cavity is communicated with a thick liquid outlet connector. The lower portion, located below the sealing base, of the cavity is communicated with an inlet connector. A compressing nut is arranged at the upper end of the valve body. The valve rod and the compressing nut are matched in a threaded mode so that the compressing nut can move in the axial direction of the valve rod. The lower end of the valve rod penetrates through the cavity and is matched with the sealing base in a sealing mode. Components ranging from the valve rod to a valve base and from an inner sleeve to an outlet and the like are all of a structure made of hard alloy materials so that the strength and the abrasion-resistant degree of the whole valve and the portion easy to abrade can be enhanced, and therefore the service life of the valve is prolonged and the safety performance of the valve is improved.
Description
Technical field
The invention belongs to construction field, relate to a kind of wear-resisting high pressure valve, relate in particular to a kind of for all kinds of slip casting overfall pressure, the adjusting of flow and the wear-resisting high pressure valves of control such as water conservancy and hydropower industry curtain-grouting, fixed slip castings.
Background technique
Growing along with Modern Construction Technology, the using scope of pressure regulator is more and more extensive, and requires that this device regulates pressure high (rated pressure 20Mpa), long service life, durable wear, easy to maintenance, performance safety is reliable.Take Hydroelectric Project Construction as example, the product of current similar purposes has: ball valve, the high pressure valve that common material is made, the high pressure valve of ceramic material etc.In use there is following problem in these products: ball valve is mainly used for regulating the liquid take water as medium, and in the time that medium is cement slurry, sealed spheroid is easily washed away grooving by slurries, loses the effect that sealing regulates; The regulating valve that common material is made is under other media such as cement slurry wash away at a high speed, and cylindrical shell and valve rod Fast Wearing, form cylindrical shell hole and valve rod lateral trench, thereby the regulating action of losing, once slurries penetrate from hole, can damage operator, there is great potential safety hazard; The pressure regulating valve of ceramic material, strong by its material fragility, under pressure punching press and site operation easily smash, thereby the regulating action of losing, and ceramic valve purchasing price is high, easy-maintaining not, therefore user cost is high, it is frequent to change.Above-described a few series products, ubiquity causes the problem that construction cost is high because working life is short, also there is the problem that has potential safety hazard because the material using is not firm, particularly regulating valve in work progress if there is fault, will cause a series of chain reactions, cause larger engineering safety accident.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, and a kind of wear-resisting high pressure valve that can effectively improve working life and Safety performance providing.
The object of the present invention is achieved like this:
A kind of wear-resisting high pressure valve, comprise valve body, in valve body, be provided with a chamber, in valve body, be provided with sealing seat, chamber one side is communicated with pulp joint, and the bottom that chamber is positioned under sealing seat is communicated with inlet union, valve body upper end is provided with clamping nut, valve rod and clamping nut form can be along the screw-thread fit of valve rod axial motion, and valve rod lower end penetrates in chamber, and forms and be sealed and matched with sealing seat.
Described valve rod lower end has a conical section, and the part of this conical section enters in the through hole of sealing seat, and the conical surface of conical section and the endoporus of sealing seat form and be sealed and matched.
Described chamber inner wall is provided with alloy sheath.
Described alloy sheath adopts cemented carbide.
Described valve rod lower end is provided with alloy housing.
Described alloy housing adopts cemented carbide.
The upper end of described valve rod is connected with handle, and by the first nut axial restraint.
Between described valve rod outer wall and valve interior wall, be provided with Sealing.
Between described clamping nut and Sealing, be provided with spring.
The present invention has obtained following technique effect:
The present invention has adopted from valve rod to valve seat, from the interior whole structures that adopt Hardmetal materials such as outlet that are set to, and can strengthen the entirety of valve and the intensity at position easy to wear and rub proofness, thereby improve working life and the Safety performance of valve.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is plan view of the present invention.
Embodiment
A kind of wear-resisting high pressure valve as shown in Figure 1, comprise valve body 9, in valve body 9, be provided with a chamber 2, in valve body 9, be provided with sealing seat 12, chamber 2 one sides are communicated with pulp joint 13, and the bottom that chamber 2 is positioned under sealing seat 12 is communicated with inlet union 10, valve body 9 upper ends are provided with clamping nut 4, it is characterized in that: valve rod 6 forms with clamping nut 4 can be along the screw-thread fit of valve rod 6 axial motions, and valve rod 6 lower ends penetrate in chamber 2, and form and be sealed and matched with sealing seat 12.Valve rod 6 lower ends have a conical section, and the part of this conical section enters in the through hole of sealing seat 12, and the endoporus of the conical surface of conical section and sealing seat 12 forms and is sealed and matched.Chamber 2 inwalls are provided with alloy sheath 7.Alloy sheath 7 adopts cemented carbide.Valve rod 6 lower ends are provided with alloy housing 11.Alloy housing 11 adopts cemented carbide.The upper end of valve rod 6 is connected with handle 3, and by the first nut 1 axial restraint.Between valve rod 6 outer walls and valve body 9 inwalls, be provided with Sealing 8.Between clamping nut 4 and Sealing 8, be provided with spring 5.
Adopt when said structure, by rotatable handle make valve rod move vertically regulating valve stem bottom with the openings of sizes of sealing seat, thereby reach by controlling the size of chamber 2 internal pressures the object of controlling valve rod two ends fluid flow like this.Slurries enter from entering to starch joint, and in the time that rotatable handle upwards promotes sub warhead, the flow of chamber 2 interior slurries strengthens; In the time that rotatable handle moves down sub warhead, the flow of chamber 2 interior slurries reduces.Last slurries are flowed out and are entered associated pipe by pulp joint.
