Abstract
The utility model discloses a kind of overhead-valve mechanism of reciprocating pump, comprise the overhead-valve bar be located on the pump housing, the bottom of the pump housing is located at by described overhead-valve bar; Described overhead-valve mechanism also comprises and is set in the collar on described overhead-valve bar, and described collar inserts the degree of depth of the pump housing for limiting overhead-valve bar.Overhead-valve mechanism of the present utility model does not need to disassemble the pump housing when pump housing inspection and maintenance can discharge residual medium in pump chamber, during maintenance especially for the pump housing of the danger medium such as the poisonous tool of conveying, harmful, radioactivity, can not produce working site and pollute, also can not produce the health of operator and threaten, it is simple that it has structure, simple operation, facilitates the advantage that the pump housing overhauls.
Description
Technical field
The utility model relates to reciprocating pump technical field, is specifically related to a kind of pump housing overhead-valve mechanism of reciprocating pump.
Background technique
Reciprocating pump is the positive displacement pump relying on the to-and-fro motion in pumping cylinder of piston, plunger or barrier film that swept volume in cylinder is alternately increased and reduce to carry liquid or make it supercharging.The pump chamber of traditional reciprocating pump is cut off formation cavity by the internal valve of the pump housing, therefore when the reciprocating pump pump housing needs to safeguard and overhaul, the pump housing is needed to disassemble, could by residual media discharge wherein out, bring great inconvenience to like this inspection and maintenance work of the pump housing, easily affect the clean of working site, and when reciprocating pump fed sheet of a media is poisonous and harmful liquid, discharge can threaten to the health of staff at the scene, simultaneously easily damages environment.
Model utility content
For prior art above shortcomings, the purpose of this utility model is to provide a kind of pump housing overhead-valve mechanism of reciprocating pump.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
An overhead-valve mechanism for reciprocating pump, comprise the overhead-valve bar be located on the pump housing, the bottom of the pump housing is located at by described overhead-valve bar; Described overhead-valve mechanism also comprises and is set in the collar on described overhead-valve bar, and described collar inserts the degree of depth of the pump housing for limiting overhead-valve bar.
In this programme, the overhead-valve mechanism of reciprocating pump comprises the overhead-valve bar be located at bottom the pump housing and the collar be set on overhead-valve bar, and wherein collar inserts the degree of depth of the pump housing for limiting overhead-valve bar.During concrete enforcement, overhead-valve bar and the pump housing adopt worm structure to be connected, when the pump housing needs inspection and maintenance, first overhead-valve bar is twisted loosening, then take off collar, be more upwards screwed into overhead-valve bar, suction valve backs down by overhead-valve bar, make the residual medium in pump housing separate space flow into pump housing suction chamber, then discharged by the inlet pipeline in the pump housing or discharge pipe.
As optimization, one end that described overhead-valve bar gos deep into the pump housing is provided with groove along the circumferential direction, is provided with O-ring seals close-fitting with pump housing inwall in this groove.
In this programme, be provided with groove along the circumferential direction in one end that overhead-valve bar gos deep into the pump housing, and be provided with O-ring seals close-fitting with pump housing inwall in a groove, improve the sealing between overhead-valve bar and pump housing inwall.
Compared to existing technology, the utility model has following beneficial effect:
1, the overhead-valve mechanism in the utility model comprises overhead-valve bar and collar, by collar regulate overhead-valve bar go deep into the pump housing the degree of depth, and then the residual liquid in pump housing separate space can be made to be discharged; Such overhead-valve mechanism does not need to disassemble the pump housing when pump housing inspection and maintenance can discharge residual medium in pump chamber, during maintenance especially for the pump housing of the danger medium such as the poisonous tool of conveying, harmful, radioactivity, can not produce working site and pollute, also can not produce the health of operator and threaten, it is simple that it has structure, simple operation, facilitates the advantage that the pump housing overhauls.
2, the one end going deep into the pump housing at overhead-valve bar is provided with O-ring seals, and sealing circle fits snugly between the groove of overhead-valve bar and pump housing inwall, improves sealing therebetween.
Accompanying drawing explanation
Fig. 1 is structural scheme of mechanism of the present utility model.
In figure, 1-pump housing separate space, 2-suction valve, 3-pump housing suction chamber, 4-pump housing, 5-O-ring seals, 6-collar, 7-overhead-valve bar.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of overhead-valve mechanism of reciprocating pump, comprise the overhead-valve bar 7 be located on the pump housing 4, the bottom of the pump housing is located at by described overhead-valve bar 7; Described overhead-valve mechanism also comprises and is set in the collar 6 on described overhead-valve bar 7, and described collar 6 inserts the degree of depth of the pump housing 4 for limiting overhead-valve bar 7.One end that described overhead-valve bar 7 gos deep into the pump housing 4 is provided with groove along the circumferential direction, is provided with the close-fitting O-ring seals 5 with pump housing inwall in this groove.
During concrete enforcement, reciprocating pump also comprises pump housing separate space 1, suction valve 2, pump housing suction chamber 3 and the pump housing 4; Wherein the bottom of the pump housing 4 is located at by overhead-valve bar 7, adopts be threaded with the pump housing 4.Overhead-valve bar 7 is arranged with collar 7, the degree of depth that collar 6 gos deep in the pump housing 4 for limiting overhead-valve bar 7 when overhead-valve bar 7 moves; The one end going deep into the pump housing 4 at overhead-valve bar 7 is also provided with O-ring seals 5.When needs carry out inspection and maintenance to the pump housing 4, first overhead-valve bar 7 is twisted loosening, again collar 6 is taken off, again overhead-valve bar 7 is upwards screwed in the pump housing 4, overhead-valve bar 7 moves upward, back down suction valve 2, make the residual medium in pump housing separate space 1 flow into pump housing suction chamber 3, discharge finally by the inlet pipeline in the pump housing 4 or discharge pipe.
Above-described embodiment of the present utility model is only for the utility model example is described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, other multi-form change and variations can also be made on the basis of the above description.Here cannot give exhaustive to all mode of executions.Every belong to the technical solution of the utility model the apparent change of amplifying out or variation be still in the row of protection domain of the present utility model.
