Abstract
The utility model discloses a hand -held type hydraulic crushing pick switching -over valve case, including under, barrel of last barrel, well barrel, last barrel, well barrel, barrel down, from the top down distributes for a whole in proper order, its whole machine -shaping, the external diameter of well barrel is greater than respectively the external diameter of upper and lower barrel, the upper and lower end of well barrel respectively with lower extreme, the lower peripheral annular edge that forms in the upper end junction of barrel of last barrel. The utility model overcomes prior art's is not enough, and the project organization is equitable, has annular edge around the upper and lower barrel respectively, forms different hydraulic pressure lifting surface areas respectively, has improved the velocity of movement of hydraulic crushing pick execution device to the work efficiency of hydraulic crushing pick has been improved.
Description
Technical field
This utility model relates to hand-held type hydraulic breakup pick parts technical field, particularly belongs to a kind of hand-held type hydraulic breakup pick change-over valve core。
Background technology
Hydraulic breakup pick has that work efficiency height, noise be little, highly reliable, the advantage of small in volume, it is adaptable to the broken disintegration of Colophonium, cement pavement, the crushing operation of armored concrete and less than 1 meter large volume building stones of diameter。Wherein internal commutation valve body and spool are its critical components, existing commutation valve body, it is by upper pick body and valve body separate machined, processing quality of fit requires height, processing technique is complicated, the design of hydraulic pressure lifting surface area is unreasonable, and the movement velocity of hydraulic breakup pick performer is fast not, causes inefficiency。
Utility model content
The purpose of this utility model there is provided a kind of hand-held type hydraulic breakup pick change-over valve core, overcomes the deficiencies in the prior art, designs rational in infrastructure, and upper pick body is reduced the fault point by commutation valve body with valve body fusion。The surrounding of the upper and lower cylinder of reversing valve core is respectively provided with annular edge edge, forms different hydraulic pressure lifting surface areas respectively, improves the movement velocity of hydraulic breakup pick performer, thus improve the work efficiency of hydraulic breakup pick。
The technical solution adopted in the utility model is as follows:
A kind of hand-held type hydraulic breakup pick change-over valve core, spool includes upper shell, middle cylinder body, lower shell, described upper shell, middle cylinder body, lower shell, it is sequentially distributed as a whole from top to bottom, its overall processing molding, the external diameter of described middle cylinder body is respectively greater than the external diameter of described upper and lower cylinder, and described middle cylinder body upper and lower end forms annular edge edge with the periphery, junction, upper end of the lower end of described upper shell, lower shell respectively, moves in valve body。
The external diameter of described upper shell is less than the external diameter of described lower shell。
Described lower shell is identical with middle cylinder body internal diameter more than upper shell internal diameter。
Described middle cylinder body and the upper and lower cylinder of upper and lower cylinder junction are respectively equipped with annular groove。
Compared with the prior art, the beneficial effects of the utility model are as follows:
This utility model is rational in infrastructure, upper pick body is merged by commutation valve body with valve body, reduce the fault point, wherein reversing valve core adopts the tube structure that three sections of external diameters are different, the upper and lower end making middle cylinder body is respectively provided with annular edge edge in the surrounding of upper and lower cylinder, form different hydraulic pressure lifting surface areas respectively, improve the movement velocity of hydraulic breakup pick performer, thus improve the work efficiency of hydraulic breakup pick。

Detailed description of the invention
Referring to accompanying drawing, for making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。
A kind of hand-held type hydraulic breakup pick change-over valve core, wherein reversing valve core includes upper shell, middle cylinder body, lower shell, described upper shell, middle cylinder body, lower shell, it is sequentially distributed as a whole from top to bottom, its overall processing molding, the external diameter of described middle cylinder body 2 is respectively greater than described upper shell 1, the external diameter of lower shell 3, on described middle cylinder body 2, lower end respectively with the lower end of described upper shell 1, the periphery, junction, upper end of lower shell 3 forms annular edge along 4, the external diameter of upper shell is less than the external diameter of described lower shell, lower shell is identical with middle cylinder body internal diameter more than upper shell internal diameter, middle cylinder body is with upper, lower shell junction upper, lower shell is respectively equipped with annular groove 5。This utility model is rational in infrastructure, adopt the tube structure that three sections of external diameters are different, the upper and lower end making middle cylinder body is respectively provided with annular edge edge in the surrounding of upper and lower cylinder, form different hydraulic pressure lifting surface areas respectively, improve the movement velocity of hydraulic breakup pick performer, thus improve the work efficiency of hydraulic breakup pick。
It should be noted that, in this article, such as term " including ", " comprising " or its any other variant are intended to comprising of nonexcludability, so that include the process of a series of key element, method, article or equipment not only include those key elements, but also include other key elements being not expressly set out, or also include the key element intrinsic for this process, method, article or equipment。When there is no more restriction, statement " including ... " key element limited, it is not excluded that there is also other identical element in including the process of described key element, method, article or equipment。
Above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model。
