Abstract
The utility model discloses a taper sleeve. The taper sleeve comprises a taper sleeve body, wherein the taper sleeve body is provided with a central hole, the position, which corresponds to the central hole, on the upper surface of the taper sleeve body is downwards depressed, and thus an arc surface is formed. The taper sleeve disclosed by the utility model has the beneficial effects that larger particulate matters in slurry can easily slide from the arc surface to the central hole and cannot be clamped on a matching surface between a rubber ball and the taper sleeve.
Description
Technical field
The utility model is specifically related to a kind of coning sleeve.
Background technique
The clack box coning sleeve upper surface used of existing plunger pump is a plane, there is a center hole in the central authorities of coning sleeve, rubber ball is just placed in the upper surface of coning sleeve, between rubber ball and coning sleeve, be almost that line contacts, when taking out slurry, the particulate matter that in slurries, particle diameter is larger is difficult for from the landing of coning sleeve upper surface, to the center hole of coning sleeve, being easily stuck on the fitting surface between rubber ball and coning sleeve.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of coning sleeve, and particulate matter larger in slurries can not be stuck on the fitting surface between rubber ball and coning sleeve.
The utility model solves the problems of the technologies described above by the following technical programs: a kind of coning sleeve, comprise coning sleeve body, this coning sleeve body has a center hole, and the upper surface of this coning sleeve body to lower recess, forms an arc surface corresponding to described central hole.
Preferably, the height of described arc surface is 21cm.
Preferably, on described arc surface, the long corresponding maximum central angle of the circular arc between 2 is obtuse angle.
The beneficial effects of the utility model are: in slurries larger particulate matter easily from described arc surface landing to described center hole, can not be stuck on the fitting surface between rubber ball and coning sleeve.
Accompanying drawing explanation
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the sectional elevation of a kind of coning sleeve of the utility model.
Fig. 2 is the cooperation figure of coning sleeve and rubber ball in the utility model.
Embodiment
Refer to Fig. 1-2, a kind of coning sleeve, comprises coning sleeve body 1, this coning sleeve body 1 has a center hole 11, the upper surface of this coning sleeve body 1 to lower recess, forms an arc surface 12 corresponding to described center hole 11 places, the setting that matches with a rubber ball 2 of described arc surface 12.
Referring again to Fig. 1, the height H of described arc surface 12 is 21cm, so that rubber ball 2 sinks into part in described arc surface 12 multiple spot as far as possible.The long corresponding maximum central angle alpha of circular arc on described arc surface 12 between 2 is obtuse angle, and described arc surface 12 can be coordinated better with rubber ball 2.
Referring again to Fig. 2, when the work of application the utility model, rubber ball 2 and coning sleeve are all arranged in the clack box of plunger pump, and rubber ball 2 is placed on coning sleeve, and the part surface of rubber ball 2 seals up the described arc surface 12 of coning sleeve; When taking out when slurry, coning sleeve and rubber ball 2 are separated, due to the setting of described arc surface 12, in slurries larger particulate matter also easily from described arc surface 12 landings to described center hole 11, thereby can not be stuck on the fitting surface between rubber ball 2 and coning sleeve.
Claims (3)
1. a coning sleeve, comprises coning sleeve body, and this coning sleeve body has a center hole, it is characterized in that: the upper surface of this coning sleeve body to lower recess, forms an arc surface corresponding to described central hole.
2. a kind of coning sleeve as claimed in claim 1, is characterized in that: the height of described arc surface is 21cm.
