Description
Technical field
The utility model belongs to diaphragm pump technical field, and in particular to a kind of fission applied to large-scale membrane pump fluid end
Assembled valve cone guiding device.
Background technique
Membrane pump fluid end valve cone is located at the inside of valve housing, and valve cone guiding device plays in actual moving process at the scene
The effect in control valve coning motion direction.For conventional membrane pump hydraulic end valve cone guiding device, structure is integrated casting
Structure, the not only manufacturing cost of this structure is high, the production cycle is long, more exists because the presence of certain casting shortcomings affects the part
Using effect under periodic shock load.
Summary of the invention
The utility model provides that a kind of structure is simple, and low production cost is with long service life aiming at the above problem
The seperated assembled valve cone guiding device of diaphragm pump.
In order to realize the above-mentioned purpose of the utility model, the utility model adopts the following technical solution, the utility model packet
Include housing and inner tube, it is characterised in that: the housing is provided centrally with stepped hole, the head of said inner tube and ladder bore dia compared with
Big part cooperation；The lesser part of tube body and ladder bore dia of inner tube cooperates；Between the head and housing of said inner tube
Gap at be provided with the fastening screw of housing and inner tube locking positioning；Housing edge is provided with connection corresponding with valve deck
Hole.
As a kind of preferred embodiment of the utility model, the sleeve surface is set corresponding to the lesser part of ladder bore dia
It is equipped with exit orifice；Exit orifice is provided with inner hole in said inner tube.
Further, the exit orifice and inner hole are provided with four groups, and two groups of adjacent angles between inner hole and exit orifice are
90°。
As another preferred embodiment of the utility model, said inner tube end is provided with the wear-resistant sleeve mounting groove of valve cone.
The utility model has the beneficial effects that the utility model not only solves traditional integrally casting formula valve cone guiding device casting
The practical problem that difficulty is big, the production cycle is long is made, the service life of the part also greatly improved, reduce use cost, that is, work as
When a certain component damages in split type valve cone guiding device, it is only necessary to be replaced to a certain component.In addition, this is practical
It is novel also have both structure novel, strong operability, it is easy to process, low in cost many advantages, such as.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment
The utility model includes housing 6 and inner tube 3, it is characterised in that: the housing 6 is provided centrally with stepped hole 2, described
The part that the head 4 of inner tube 3 and stepped hole 2 are relatively large in diameter cooperates；The tube body of inner tube 39 and the lesser part of 2 diameter of stepped hole
Cooperation；It is provided at gap between the head 4 and housing 6 of said inner tube 3 by the fastening spiral shell of 3 locking positioning of housing 6 and inner tube
Nail 5；6 edge of housing is provided with connecting hole 1 corresponding with valve deck 12.
As a kind of preferred embodiment of the utility model, 6 surface of housing corresponds to the lesser part of 2 diameter of stepped hole
It is provided with exit orifice 7；Exit orifice 7 is provided with inner hole 8 in said inner tube 3.
Further, the exit orifice 7 and inner hole 8 are provided with four groups, the angle between two groups of adjacent inner holes 8 and exit orifice 7
It is 90 °.
As another preferred embodiment of the utility model, 3 end of said inner tube is provided with the wear-resistant sleeve 11 of valve cone 13
Mounting groove 10.
When assembly, valve deck 12 is removed, housing 6 and inner tube 3 are locked using interior hexagonal flush end fastening screw 5, utilize interior six
The housing 6 assembled and inner tube 3 are fixed on 12 lower end surface of valve deck by connecting hole 1 by angle fillister head screw, the internal diameter of inner tube 3 with
There are certain intervals between 13 outer diameter of valve cone, to control the up and down motion of valve cone 13.
When some part destroys under the action of periodic shock load in housing 6 and inner tube 3, it is only necessary to damage
Bad part is replaced, and other components that do not damage can still use as usual.
It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being
It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technical effect；Needs are used as long as meeting, all in this reality
Within novel protection scope.
