Abstract
The utility model discloses a valve bush of a hydraulic pressure reversing valve. The valve bush comprises a hollow cylinder-shaped overflowing sleeve, a first sealing guide sleeve and a second sealing guide sleeve, wherein the second sealing guide sleeve, the overflowing sleeve and the first sealing guide sleeve are installed in turn; and a plurality of strip-shaped holes which can communicating the interior of the overflowing sleeve are uniformly arranged on the side wall of the overflowing sleeve. The overflowing sleeve, the first sealing guide sleeve and the second sealing guide sleeve are assembled to form the valve bush, such that a conventional integral-type valve bush is changed into a split-type valve bush, and thus the processing difficulty is lowered; the overflowing sleeve is made from stainless steel and thus is long in service life; when the valve bush is abraded, all the three parts can be directly replaced and are convenient to replace; and usage of raw materialcopper rods can be reduced, thus to reduce processing costs.
Description
Technical field
The utility model relates to a kind of hydraulic pressure selector valve, especially a kind of valve pocket of hydraulic pressure selector valve.
Background technique
Valve pocket is the part that high pressure water water (flow) direction is controlled in relative movement with spool, the valve pocket using in original device is the tubular member of 8 apertures of circumference uniform distribution of being formed by the method for machining by bronze pole, valve pocket two ends are processed with the groove that seal ring is installed, centre is evenly equipped with the bar hole that high pressure water passes through, valve pocket is an integrally-built valve pocket, valve pocket structure is more complicated, difficulty of processing is large, machining accuracy is low, this device in use, valve pocket intermediate portion is easily by high pressure water impact, corrode, cause valve bush part to lose efficacy, the part of copper material is short working life, replacement cost is high, be unfavorable for that enterprise reduces production costs.
Model utility content
The shortcomings such as the purpose of this utility model, is to provide a kind of valve pocket of hydraulic pressure selector valve, and it is large that it overcomes valve bush part difficulty of processing, the deficiency that machining accuracy is low and working life is short.
The solution that the utility model solves its technical problem is: a kind of valve pocket of hydraulic pressure selector valve, it comprises columned overcurrent cover, the first seal guide sleeve and second seal guide sleeve of hollow, described the second seal guide sleeve, overcurrent cover and the first seal guide sleeve are installed successively, be evenly arranged many and can be communicated with overcurrent and overlap inner bar hole on the sidewall of described overcurrent cover.
As the further improvement of technique scheme, in described the second seal guide sleeve, dust ring and seal ring are installed, in described the first seal guide sleeve, seal ring is installed.
As the further improvement of technique scheme, the two ends of described overcurrent cover all arrange installation base, and described the first seal guide sleeve is provided with the installation groove mating with installation base, and described the second seal guide sleeve is provided with the installation groove mating with installation base.
As the further improvement of technique scheme, described bar hole distributes along the even circumferential of the cross section of overcurrent cover.
As the further improvement of technique scheme, described overcurrent cover is stainless steel component, and described the first seal guide sleeve and the second seal guide sleeve are tin bronze member.
The beneficial effects of the utility model are: the utility model is by arranging overcurrent cover, the first seal guide sleeve and the second seal guide sleeve, after being assembled, form valve pocket, such setting, becomes the all-in-one-piece valve pocket of script into split type valve pocket, reduce difficulty of processing, overcurrent cover is stainless steel component, and working life is longer, in the time that valve pocket weares and teares, three parts all can directly be changed, and it is convenient to change, and can reduce the use of raw material copper rod, cuts down finished cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than whole embodiment, and those skilled in the art is not paying under the prerequisite of creative work, can also obtain other design proposals and accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is explosive view of the present utility model.
Embodiment
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is clearly and completely described, to understand fully the purpose of this utility model, feature and effect.Obviously; described embodiment is a part of embodiment of the present utility model, rather than whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite of not paying creative work, all belong to the scope that the utility model is protected.In addition, all connection/annexations of mentioning in literary composition, not singly refer to that member directly joins, and refer to and can, according to concrete performance, connect auxiliary by adding or reducing, and form more excellent connecting structure.
With reference to Fig. 1～Fig. 2, a kind of valve pocket of hydraulic pressure selector valve, it comprises columned overcurrent cover 1, the first seal guide sleeve 2 and second seal guide sleeve 3 of hollow, described the second seal guide sleeve 3, overcurrent cover 1 and the first seal guide sleeve 2 are installed successively, and described overcurrent overlaps and on 1 sidewall, is evenly arranged many bar holes 4 that can be communicated with overcurrent and overlap 1 inside.
By overcurrent cover 1, the first seal guide sleeve 2 and the second seal guide sleeve 3 are set, after being assembled, form valve pocket, such setting, the all-in-one-piece valve pocket of script is become to split type valve pocket, reduce difficulty of processing, in the time that valve pocket weares and teares, three parts all can directly be changed, and it is convenient to change, and can reduce the use of raw material copper rod, cuts down finished cost.
Be further used as preferred embodiment, in described the second seal guide sleeve 3, dust ring and seal ring be installed, the dustproof dustproof effect that encloses; In described the first seal guide sleeve 2, seal ring is installed, seal ring mainly works to prevent that high pressure water from flowing out from the first seal guide sleeve 2 or the second seal guide sleeve 3.
Be further used as preferred embodiment, the two ends of described overcurrent cover 1 all arrange installation base 5, described the first seal guide sleeve 2 is provided with the installation groove 6 mating with installation base, described the second seal guide sleeve 3 is provided with the installation groove 6 mating with installation base, and installation base 5 and the installation position interference of installing between groove 6 are installed.
Be further used as preferred embodiment, described bar hole 4 distributes along the even circumferential of the cross section of overcurrent cover 1, makes high pressure water turnover valve pocket.
Be further used as preferred embodiment, described overcurrent cover 1 is stainless steel component, and working life is longer, and described the first seal guide sleeve 2 and the second seal guide sleeve 3 are tin bronze member.
More than that preferred embodiments of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
