Description
Technical field
The utility model belongs to diaphragm pump field, is specifically related to a kind of valve block of diaphragm pump.
Background technique
Along with the raising of people's living standard, water purifier has started to enter huge numbers of families, but the diaphragm pump on existing water purifier easily produces leakage water problem after using a period of time.This caused due to existing barrier film pump structure and working principle.Diaphragm pump mainly comprises electric machine assembly and pump head, the pump head structure of existing a kind of diaphragm pump, and it is primarily of upper cover, O shape circle, valve block, valve seat, piston seat, delta-ring, small sucker, piston, screw, diaphragm, escapement, escapement seat etc.Diaphragm has three boss, and it forms three sealed high pressure rooms together with piston seat.A piston is provided with in each seal area, piston is provided with screw hole, piston is connected with escapement by screw, bearing is embedded with in escapement, eccentric wheel is embedded with in bearing, eccentric wheel is connected with the motor output shaft of electric machine assembly, by the acting in conjunction of eccentric wheel and escapement, drives piston to do reciprocal class straight line motion and carries out pump water.
Existing a kind of barrier film this valve block as shown in Figures 4 and 5, it comprises the outer spherical surface of half ball cover 10, half ball cover 10 and valve seat 50 internal surface is fitted.Half ball cover 10 is provided with attachment post 30, attachment post 30 is generally one-way valve, in order to realize the unidirectional conveying of water between inner ball surface and outer spherical surface, this attachment post 30 is planted in valve seat 50 to realize the connection of valve block and valve seat 50, on the outer spherical surface of valve block, be provided with three positioning bars 40 simultaneously, valve seat 50 offers the groove coordinated with positioning bar 40, by the cooperation of positioning bar 40 and groove, valve block is fitted on valve seat 50 better.Generally in the inner ball surface of valve block, be provided with three elastic rib 20, article three, elastic rib 20 extends from attachment post 30 to the opening end of half ball cover 10, valve seat 50 is provided with drain opening, the effect of these three elastic rib 20 is pushed back by valve block on valve seat 50 by its elasticity in water absorption course, and fit tightly with it, by weep hole shutoff.Valve block is pushed away barrier film seat by the pressure produced by piston in drainage procedure, thus water is discharged from weep hole.The valve block of this kind of structure, because doing opening and closing movement for a long time, in addition in pump working process, three hyperbaric chambers are opened in turn, the different parts of valve block can be involved, and makes material easily produce fatigue deformation, and valve plate material is aging in addition, and the long-term stressed effect of valve seat, also can produce aging distortion, after running after a while, valve block and valve seat just can not be fitted completely like this, and diaphragm pump will be made like this to produce decompression, suction capacity declines, the problems such as water-outlet quantity minimizing.
Given this, the present inventor carries out deep research to the problems referred to above, then has this case to produce.
Model utility content
The purpose of this utility model is the valve block providing the better diaphragm pump of a kind of longer service life, sealing effect.
In order to achieve the above object, the utility model adopts such technological scheme:
A kind of valve block of diaphragm pump, comprise half ball cover in order to coordinate with the valve seat of diaphragm pump, the inner ball surface of half ball cover is provided with elastic rib, the outer spherical surface of half ball cover is provided with positioning bar, also comprise the attachment post be connected on half ball cover, attachment post is connected in valve seat, and elastic rib extends from attachment post to the opening end of half ball cover, also comprise the slot segmentation between the opening end being arranged on elastic rib and half ball cover, slot segmentation is through to outer spherical surface from inner ball surface.
As a kind of optimal way, described elastic rib is three, evenly be connected to the outer wall of described attachment post radially, elastic rib correspondence described in every bar arranges a described slot segmentation, and described half ball cover is separated into three identical little valve blocks of size by three described slot segmentations.
Further, described little valve block is provided with stiffening rib near the edge of described slot segmentation, and stiffening rib is arranged in the inner ball surface of described half ball cover.
Further, the position that described little valve block is corresponding with the osculum of described valve seat forms the thinner wall section that thickness is less than described little other position of valve block.
Adopt after the technical solution of the utility model, overcome different hyperbaric chamber in prior art and open mutually involving between the valve block different parts that causes in turn, improve sealing effect, the aging of valve block can be extended, improve the working life of valve block.
By arranging stiffening rib to strengthen the elasticity of valve block, ensureing that valve block uses for a long time, extending the working life of valve block.
By the reduced thickness by position corresponding with the osculum of described valve seat for little valve block, form thinner wall section, when piston water-suction, this thinner wall section is more prone to distortion and fits with the inner ball surface of valve seat under the effect of suction, even if because valve seat is aging, valve block of the present utility model also can be fitted in inner ball surface well, and sealing effect is good, extends the working life of valve block.

Embodiment
In order to explain the technical solution of the utility model further, be described in detail below in conjunction with accompanying drawing.
Referring to figs. 1 through Fig. 3, a kind of valve block of diaphragm pump, comprise half ball cover 10 in order to coordinate with the valve seat 50 of diaphragm pump, the inner ball surface of half ball cover 10 is provided with elastic rib 30, the outer spherical surface of half ball cover 30 is provided with positioning bar 40, also comprise the attachment post 20 be connected on half ball cover 10, attachment post 20 is connected in valve seat 50, and elastic rib 30 extends from attachment post 20 to the opening end of half ball cover 10.The utility model also comprises the slot segmentation 60 be arranged between elastic rib 30 and the opening end 12 of half ball cover 10, and slot segmentation 60 is through to outer spherical surface from inner ball surface.
As a kind of optimal way, described elastic rib 30 is three, evenly be connected to the outer wall of described attachment post 20 radially, elastic rib 30 correspondence described in every bar arranges a described slot segmentation 60, described half ball cover 10 is separated into the identical little valve block of size by three slot segmentations 60, one end of little valve block is connected with attachment post 20 and elastic rib 30, the other end is free end, by half ball cover 10 is divided into three little valve blocks, avoids three high-pressure chamber in diaphragm pump and open in turn to cause between the different parts of half ball cover and mutually involve.
Improve further as the utility model, described little valve block is provided with stiffening rib 70 near the edge of described slot segmentation 60, and stiffening rib 70 is arranged in described inner ball surface, and each little valve block like this arranges two stiffening ribs 70 to increase the elasticity of little valve block.
As further improvement of the utility model, the position that described little valve block is corresponding with the osculum 51 of described valve seat 50 forms the thinner wall section 11 that thickness is less than described little other position of valve block.When the piston water-suction of diaphragm pump, this thinner wall section 11 can be fitted with the inner ball surface of valve seat 50 better.
Product form of the present utility model is not limited to this case diagram and embodiment, and anyone carries out suitable change or the modification of similar thinking to it, all should be considered as not departing from patent category of the present utility model.
