Abstract
A high-pressure valve resistant to abrasion comprises a valve body, a chamber is arranged inside the valve body, a seal seat is arranged inside the valve body, one side of the chamber is communicated with a slurry outlet joint, and the chamber is placed below the seal seat and is communicated with an inlet joint. The upper end of the valve body is provided with a press nut, a valve rod and the press nut form a screw thread fit which can enable the valve rod and the press nut to move along the axial direction of the valve rod, and the lower end of the valve rod penetrates into the chamber and forms a seal fit with the seal seat. According to the high-pressure valve resistant to the abrasion, the valve rod, a valve seat, an inner sleeve, an outlet and other parts all utilize the structures of hard alloy material, the strength and the abrasion-resistant degree of the whole and parts prone to abrasion of the valve are enhanced, and therefore service life of the valve is prolonged, and safety performance of the valve is improved.
Description
Technical field
The invention belongs to the 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 is regulated 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 present 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 mainly is that when medium was cement slurry, sealed spheroid was easily washed away grooving by slurries for the liquid of regulating take water as medium, loses the effect that sealing is regulated; The regulating valve that common material is made washes away at a high speed lower at other media such as cement slurrys, cylindrical shell and valve rod Fast Wearing form cylindrical shell hole and valve rod lateral trench, thereby the regulating action of losing, in case slurries penetrate from hole, can damage operator, great potential safety hazard is arranged; The pressure regulating valve of ceramic material, strong by its material fragility, under the pressure punching press and site operation easily smash, thereby the regulating action of losing, and the 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 high problem of construction cost because working life is short, also there is the problem that has potential safety hazard because employed material 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 energy Effective Raise working life that provides and the wear-resisting high pressure valve of Safety performance.
The object of the present invention is achieved like this:
A kind of wear-resisting high pressure valve, comprise valve body, be provided with a chamber in the valve body, be provided with sealing seat in the valve body, chamber one side is communicated with the pulp joint, and the bottom that chamber is positioned under the sealing seat is communicated with inlet union, the valve body upper end is equipped with clamping nut, valve rod and clamping nut form can be along the screw-thread fit of valve rod axial motion, and the valve rod lower end penetrates in the chamber, and is sealed and matched with sealing seat formation.
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 the 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.
Be provided with Sealing between described valve rod outer wall and the valve interior wall.
Be provided with spring between described clamping nut and the Sealing.
The present invention has obtained following technique effect:
The present invention adopted from the valve rod to the valve seat, be set to the structures that Hardmetal materials are all adopted in outlet etc. from interior, can strengthen the integral body of valve and intensity and the rub proofness at position easy to wear, thereby improve working life and the Safety performance of valve.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
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, be provided with a chamber 2 in the valve body 9, be provided with sealing seat 12 in the valve body 9, chamber 2 one sides are communicated with pulp joint 13, and the bottom that chamber 2 is positioned under the sealing seat 12 is communicated with inlet union 10, valve body 9 upper ends are equipped 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 the chamber 2, and is sealed and matched with sealing seat 12 formation.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.Be provided with Sealing 8 between valve rod 6 outer walls and valve body 9 inwalls.Be provided with spring 5 between clamping nut 4 and the Sealing 8.
When adopting said structure, by rotatable handle make valve rod move vertically regulating valve stem bottom with the openings of sizes of sealing seat, thereby reach like this purpose of control valve rod two ends fluid flow by the size of control chamber 2 internal pressures.Slurries enter from advancing to starch joint, and when rotatable handle upwards promoted sub warhead, the flow of chamber 2 interior slurries strengthened; When rotatable handle moved down sub warhead, the flow of chamber 2 interior slurries reduced.Last slurries are flowed out by the pulp joint and enter associated pipe.
