Abstract
The utility model discloses a kind of separate type of fracturing pump spool, resolve into multiple part by spool, process respectively, and then be assembled into entirety, comprise sealing seat and positioning pawl, it is characterized in that: described sealing seat and positioning pawl assemble one end and be provided with cylinder, described cylinder and the through hole of positioning pawl assemble, and are fixed by rivet rivet welding with positioning pawl; Cylinder and positioning pawl are fixed by rivet welding horizontal by 45° angle by described rivet; Described rivet riveting enters end and is evenly distributed on the concentric circle of through hole, and described concentric circle is located on positioning pawl; Described rivet has 4.The utility model can reach the effect improving conforming product rate, manufacturing efficiency, reduction manufacture cost and manufacture difficulty, and described manufacturing efficiency at least improves 5 times.
Description
Technical field
The utility model relates to a kind of fracturing pump, particularly relates to a kind of fracturing pump spool.
Background technique
In prior art, the as a whole structure of fracturing pump spool, is formed by machined into, due to the positioning pawl complex structure on spool, this can cause processing dead angle in course of working, makes the very difficult and yield rate of processing, up-to-standard rate is very low, cost of production is high, can not meet customer need.
Model utility content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of separated type valve core structure, resolves into multiple part, processes respectively, and then be assembled into entirety by spool.
For achieving the above object, the utility model provides a kind of separate type of fracturing pump spool, comprise sealing seat and positioning pawl, it is characterized in that: described sealing seat and positioning pawl assemble one end and be provided with cylinder, described cylinder and the through hole of positioning pawl assemble, and are fixed by rivet rivet welding with positioning pawl.
Further, cylinder and positioning pawl are fixed by rivet welding horizontal by 45° angle by described rivet.
Further, described rivet riveting enters end and is evenly distributed on the concentric circle of through hole, and described concentric circle is located on positioning pawl.
Further, described rivet has 4.
The beneficial effects of the utility model are: the utility model can reach the effect improving conforming product rate, manufacturing efficiency, reduction manufacture cost and manufacture difficulty, and described manufacturing efficiency at least improves 5 times.
Accompanying drawing explanation
Fig. 1 is the structural representation of the separate type embodiment of the utility model one one kinds of fracturing pump spools.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See Fig. 1, a kind of separate type of fracturing pump spool, comprises sealing seat 1 and positioning pawl 2, and described sealing seat 1 assembles one end with positioning pawl 2 and is provided with cylinder 11, and described cylinder 11 assembles with the through hole 21 of positioning pawl 2, and is fixed by rivet 3 rivet welding;
Cylinder 11 and positioning pawl 2 rivet welding are preferably fixed horizontal by 45° angle by described rivet 3;
Described rivet 3 preferably has 4, and riveting enter end be evenly distributed on the concentric circle of through hole 21, described concentric circle is located on positioning pawl 2.
By this separation structure, the mode of casting can be adopted to manufacture to sealing seat 1, machining manufacture be adopted to positioning pawl 2, finally again sealing seat 1 and positioning pawl 2 is fixed as one by rivet welding; Due to the processing dead angle that positioning pawl causes when this mode efficiently avoid overall processing, and adopt the mode of casting to produce due to sealing seat, effectively can reduce the manufacture cost of sealing seat; Therefore the utility model can reach the effect improving conforming product rate, manufacturing efficiency, reduction manufacture cost and manufacture difficulty, described manufacturing efficiency at least improves 5 times.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
Claims (4)
