Abstract
The utility model discloses a kind of anticorrosive anti-wear valve core.Belong to the design and manufacturing technology field of valve.It comprises inner spool (2) and is sheathed on the outer spool (1) on described inner spool (2), and described inner spool (2) is made up of stupalith, and described outer spool (1) is made up of metallic material.This spool is applied to and spurts in ball valve containing solid material, and the inner spool that stupalith is made can ensure wear resistance and the corrosion resistance of ball valve, and meanwhile, the outer valve of metallic material can ensure the intensity of ball valve, the impact of anti-solid logistics body.
Description
Technical field
The utility model belongs to technical field of valve manufacturing, particularly a kind of anticorrosive anti-wear valve core controlling solid material circulation.
Background technique
Changeover valve is opened by a spool rotated or is cut off logistics corridor, allows fluid to flow through, by valve core rotation 90 degree of cut-out logistics when spool is in out.In valve opening process, spool will be subject to the impact of fluid, when the solid content of fluid is higher and flow velocity is very fast, very large to the wearing and tearing of spool.
Changeover valve is divided into three types according to structural type: butterfly valve, ball valve and plunger valve.Be generally adopt cast iron or steel shell at present, spool adopts high strength alloy steel body.Although alloyed steel body intensity is higher, under the fluid impact of high solid content high flow rate, still have comparatively galling, especially corrosive fluid by time valve body corroded and the impact of wearing and tearing more serious, cause valve whole service life not long.
For solving the problems of the technologies described above, Chinese patent document CN103711932 A discloses a kind of ball valve of anticorrosive anti-wear, and original metal spool is changed to corrosion resistant stupalith by this ball valve, substantially increases wear resistance and the corrosion resistance of valve body.But also bring another one problem, i.e. the insufficient strength of pottery simultaneously, frangible under the impact containing solid logistics body.
Summary of the invention
For this reason, technical problem to be solved in the utility model is that existing body strength is inadequate, problem frangible under the impact containing solid logistics body, and then provides a kind of high strength, anticorrosive, wear-resisting valve body.
For solving the problems of the technologies described above, the anticorrosive anti-wear valve core of one of the present utility model, it comprises inner spool and is sheathed on the outer spool on described inner spool, and described inner spool is made up of stupalith, and described outer spool is made up of metallic material.
In above-mentioned anticorrosive anti-wear valve core, described inner spool has columniform sleeve, and one end of described sleeve is provided with outer; Described outer valve core housing is located on described sleeve, and its end face is fitted and connected on described outer, and described outer spool and described outer surround spherical jointly.
Preferably, described outer is arranged at side, fluid inflow direction.
In above-mentioned anticorrosive anti-wear valve core, described outer spool is provided with control flume.
In above-mentioned anticorrosive anti-wear valve core, described inner spool and described outer spool are by being coated with glue bond.
Preferably, described outer spool is made up of alloyed steel.
Technique scheme of the present utility model has the following advantages compared to existing technology:
(1) anticorrosive anti-wear valve core of the present utility model, it comprises inner spool and is sheathed on the outer spool on described inner spool, and described inner spool is made up of stupalith, and described outer spool is made up of metallic material.Above-mentioned spool is applied to and spurts in ball valve containing solid material, and the inner spool that stupalith is made can ensure wear resistance and the corrosion resistance of ball valve, and meanwhile, the outer valve of metallic material can ensure the intensity of ball valve, the impact of anti-solid logistics body.
(2), in anticorrosive anti-wear valve core of the present utility model, inner spool has columniform sleeve, and one end of sleeve is provided with outer; Outer valve core housing is located on described sleeve, and its end face is fitted and connected on described outer, and described outer spool and described outer surround spherical jointly, and inner spool and outer spool are by being coated with glue bond.Said structure can make the combination of inside and outside spool more firm.
(3) outer spool of the present utility model adopts the alloyed steel heating expansion coefficient similar with stupalith to make, and be heated in the outer spool of uniform temperature by loading after inner spool gluing, fine finishing outer surface after cooling, till reaching technological requirement.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below according to specific embodiment of the utility model also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is the sectional view of anticorrosive anti-wear valve core of the present utility model;
Fig. 2 is the stereogram of anticorrosive anti-wear valve core of the present utility model.
In figure, reference character is expressed as: the outer spool of 1-, 11-control flume, 2-inner spool, 21-sleeve, 22-outer.
Embodiment
Be anticorrosive anti-wear valve core of the present utility model as shown in Figure 1, Figure 2, it comprises inner spool 2) and the outer spool 1 that is sheathed on described inner spool 2, described inner spool 2 is made up of stupalith, and described outer spool 1 is made up of metallic material.Above-mentioned spool is applied to containing in solid material blow off valve, and the inner spool that stupalith is made can ensure wear resistance and the corrosion resistance of ball valve, and meanwhile, the outer valve of metallic material can ensure the intensity of ball valve, the impact of anti-solid logistics body.
Due to alloyed steel, to have intensity high, and the advantages such as wear resistance is good, preferably, described outer spool 1 is made up of alloyed steel.Preferred, described outer spool 1 adopts the alloyed steel close with the thermal expansion coefficient of pottery.Like this, be heated in the outer spool 1 of uniform temperature by loading after inner spool 2 gluing, fine finishing outer surface after cooling, till reaching technological requirement.
Above-mentioned spool can be applied in the blow off valve of various structural type, and present embodiment illustrates a kind of concrete structure of the spool be applied in ball valve.
As shown in Figure 1, described inner spool 2 has columniform sleeve 21, and one end of described sleeve 21 is provided with outer 22; Described outer spool 1 is sheathed on described sleeve 21, and its end face is fitted and connected on described outer 22, and described outer spool 1 and described outer 22 surround spherical jointly.Both are fixed by the mode being inserted outer spool 1 by inner spool 2, and the combination of inside and outside spool can be made more firm.Described inner spool 2 and described outer spool 1 are by being coated with glue bond.
Described outer 22 is arranged at side, fluid inflow direction.The inner spool 2 that stupalith supports be can ensure to be with most of region of fluid contact, wear resistance and the corrosion resistance of valve improved.
Described outer spool 1 is provided with the control flume 11 being suitable for coordinating with ball valve switch, and described control flume 11 is long strip groove, and its length direction is perpendicular to the axis of described spool.
