Abstract
The utility model discloses a kind of chamber of septum structure, comprise pump case, described pump case forms the suction chamber sucked for medium, suction chamber is movably set with the one-way valve seat of its opening of sealing, also be included in the one-way valve seat support that suction chamber place is arranged, the protruding post being provided with fixed hole is comprised to valve seat support, protruding post upper-end surface is provided with guide pad, guide pad being provided with fastening piece and the pilot hole for passing through for one-way valve seat, realizing guide pad fixing on protruding post by fastening piece with coordinating of fixed hole.The utility model is by becoming original and the integrated protruding post of housing and these two-part of guide pad be arranged on protruding post with housing integrated one-way valve seat support Design, make the difficulty that reduce further Design of Dies on the basis not reducing original diaphragm pump effect, and avoid original matrix pump at male face place overlap on the impact in cross section, middle circular hole place, the guide structure of one-way valve support is also more reliable in addition.
Description
Technical field
The utility model relates to diaphragm pump field, more specifically, relates to the chamber of septum structure on a kind of diaphragm pump.
Background technique
This patent patent applicant and the earlier application utility model patent of " a kind of inlet valve mounting structure " by name, see accompanying drawing 1, comprise the suction chamber 10 sucked for medium, described suction chamber 1 is also provided with one-way valve seat support 35, described one-way valve seat support 35 is offered with pilot hole, one-way valve seat 30, by described pilot hole, is provided with the assembly wall that encloses upwards side direction extension around described pilot hole.When installing Returnning spring 33, first the card cap 34 Returnning spring being inserted in one-way valve seat 30(now one-way valve seat 30 is not installed), described Returnning spring 33 one end is plugged and described assembly wall, it is made to lean described one-way valve seat support 35, then buckling into card cap 34 in one-way valve seat 30 upper end makes itself and described Returnning spring 33 the other end lean, and now Returnning spring 33 is compressed between card cap and one-way valve seat support 35.And due to the leading role of one-way valve seat support 35 pairs of one-way valve seats 30, make it when straight skidding, the component of substantially horizontal can not be produced.In addition, described Returnning spring 33 is away from described suction chamber 1.Specifically, there is certain interval in described one-way valve support 35 setting position and territory, described suction chamber 1 fluid inspiration zone, due to the existence in above-mentioned gap, and spring is arranged between one-way valve support 35 and card cap 34 and (is positioned at the top in above-mentioned gap), therefore, when fluid is sucked from suction chamber 1, the foreign matter being positioned at territory, above-mentioned fluid inspiration zone also can not be attracted on Returnning spring and Returnning spring was lost efficacy.
But said structure is according to when reality uses, find that there is following defect: because one-way valve seat support 35 is one-body molded above the housing of suction chamber, therefore when actual design mould, be difficult to the formed product made in die cavity; In addition male face place overlap also has considerable influence to cross section, middle circular hole place.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of chamber of septum structure.
The utility model is achieved through the following technical solutions: a kind of chamber of septum structure, comprise pump case, described pump case forms the suction chamber sucked for medium, described suction chamber is movably set with the one-way valve seat of its opening of sealing, also be included in the one-way valve seat support that suction chamber place is arranged, described one-way valve seat is by described one-way valve seat support, Returnning spring is provided with between described one-way valve seat and described one-way valve seat support, described Returnning spring is away from described suction chamber, described one-way valve seat support comprises the protruding post being provided with fixed hole, described protruding post upper-end surface is provided with guide pad, described guide pad is provided with fastening piece and the pilot hole for passing through for one-way valve seat, guide pad fixing on protruding post is realized with coordinating of fixed hole by fastening piece.
In technique scheme, described guide pad is positioned at around pilot hole and is provided with the assembly wall that encloses upwards side direction extension, and described Returnning spring one end is sheathed on described assembly wall.
In technique scheme, described one-way valve seat upper end is provided with card cap, and the described Returnning spring the other end leans described card cap lower end surface.
The utility model has following beneficial effect: the utility model is by becoming original and the integrated protruding post of housing and these two-part of guide pad be arranged on protruding post with housing integrated one-way valve seat support Design, make the difficulty that reduce further Design of Dies on the basis not reducing original diaphragm pump effect, and avoid original matrix pump at male face place overlap on the impact in cross section, middle circular hole place, the guide structure of one-way valve support is also more reliable in addition.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional diaphragm pump water inlet valve.
Fig. 2 is the utility model structural representation.
Fig. 3 is the partial exploded view of this Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: see Fig. 2 to Fig. 3, a kind of chamber of septum structure, comprise pump case 1, described pump case 1 forms the suction chamber 10 sucked for medium, described suction chamber 10 is movably set with the one-way valve seat 3 of its opening of sealing, also be included in the one-way valve seat support 4 that suction chamber 10 place is arranged, described one-way valve seat 3 is by described one-way valve seat support 4, between described one-way valve seat 3 and described one-way valve seat support 4, be provided with Returnning spring 5, described Returnning spring 5 is away from described suction chamber 10.
Described one-way valve seat support 4 comprises the protruding post 40 being provided with fixed hole 40a, described protruding post 40 upper-end surface is provided with guide pad 41, described guide pad 41 being provided with fastening piece 42 and the pilot hole 43 for passing through for one-way valve seat 3, realizing guide pad 41 fixing on protruding post 40 by fastening piece 42 with coordinating of fixed hole 40a.By becoming original and the integrated protruding post of housing and these two-part of guide pad be arranged on protruding post with housing integrated one-way valve seat support Design, make the difficulty that reduce further Design of Dies on the basis not reducing original diaphragm pump effect, and avoid original matrix pump at male face place overlap on the impact in cross section, middle circular hole place, the guide structure of one-way valve support is also more reliable in addition.
