Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
Embodiment 1
As shown in Figures 1 to 3, a kind of controlled valve structure for emulsion pumps, the emulsion pumps of the present embodiment are proboscis pump, bag
Include the pump housing 1, suction pipe 2, piston 9, piston rod 3 and head cap 4, head cap 4 is proboscis head cap, the structure ＆ working mechanism of proboscis pump with it is normal
Rule technology is consistent, and description is not repeated herein, and controlled valve structure setting is in head cap 4, including valve 5, spring 6, valve seat 7
With bonnet 8, the extension diameter section inserted for valve seat 7 is formed near the position of spout in head cap 4, bonnet 8 covers the outside for being located at spout,
The middle part of bonnet 8 is provided with apopore 81, and the section of valve seat 7 takes the shape of the letter U, and the front end of valve seat 7 forms the annular snap coordinated with bonnet 8
Circle 73, the inner side of bonnet 8 forms the annular slot 82 of the annular collar insertion positioning for valve seat 7, and valve seat 7 passes through annular collar
With being equipped with the extension diameter section of head cap 4 for annular slot, current are left between the outside wall surface and the inwall of head cap 4 of valve seat 7 and is led to
Road, middle part is convexly equipped with the newel 71 being arranged for valve 5 in valve seat 7, valve 5 can left and right be movably mounted to the center of valve seat 7
On post 71, corrected before valve 5 and offseted with the apopore 81 of bonnet 8, the front end central aperture of valve 5, spring 6 is set in valve
Offseted with the rear end of valve 5 on the newel 71 of seat 7, make valve 5 that there is the trend for all the time closing apopore 81 to left movement,
The rear portion outer peripheral face annular of valve 5 be convexly equipped with the inwall of valve seat 7 offset sealing valve shape sealing surface 51, in sealing surface 51
The wall of the valve seat 7 in front is provided with the gap 72 for entering for liquid, in sealing surface 51 and the valve seat 7, bonnet 8 in valve 5
Liquid storage cylinder 10 is formed between wall.
Operation principle is：When pressing head cap 4, piston 9 work downwards, the liquid in bottle is up inhaled from suction pipe 2 by the pump housing 1
Enter in head cap 4, liquid enters in liquid storage cylinder 10 along water stream channel from the gap 72 of the wall of valve seat 7, the liquid in liquid storage cylinder 10
When body reaches certain pressure, valve 5 overcomes the elastic force of spring 6 to open the apopore 81 of bonnet 8 toward moving right, and liquid is from head cap
4 are sprayed, and when the pressure drops, the moment in the presence of spring 6 of valve 5, toward moving left, apopore 81 is closed.
So after having used, due to having valve 5 in head cap 4, so that it may avoid emulsion from being oozed from the proboscis of head cap 4,
Avoid wasting, moreover it is possible to keep neat and tidy.
Embodiment 2
As shown in figures 4-6, a kind of controlled valve structure for emulsion pumps, the emulsion pumps of the present embodiment are short mouth pump, bag
The pump housing 10, suction pipe 20, piston 90, piston rod 30 and head cap 40 are included, head cap 40 is short mouth cap, and the structure of short mouth pump is former with work
Reason is consistent with routine techniques, and description is not repeated herein, and controlled valve structure setting is in head cap 40, including valve 50 and bullet
Spring 60, the front end nozzle of head cap 40 is provided with nozzle 70, valve 50 can left and right be actively horizontally installed in head cap 40, valve 50
Front end offseted with the delivery port 701 of nozzle 70, the front end central aperture of valve 50, spring 60 be supported on the rear end of valve 50 with
Between the rear end inwall of head cap 40, make valve 5 that there is the trend for all the time closing delivery port 701 to left movement；After valve 50
End form ammunition feed spring 60 front end plant spring eye, on the rear end outer peripheral face of valve 50 annular be convexly equipped with head cap 40
Wall offsets the sealing surface 501 of sealing, and sealing surface 501 is located at the rear of the inlet opening 401 of head cap 40, in sealing surface 501 and head cap
40th, liquid storage cylinder 100 is formed between the inwall of nozzle 70.
Operation principle is：Pressing head cap 40, piston 90 works downwards, and the liquid in bottle is up inhaled from suction pipe 2 by the pump housing 1
Enter in the liquid storage cylinder 100 in head cap 40, when the liquid in liquid storage cylinder 100 reaches certain pressure, valve 50 overcomes the bullet of spring 60
Past the moving right of power opens the delivery port 701 of nozzle 70, and liquid sprays from nozzle 70, and when the pressure drops, valve 50 is in spring
Moment, toward moving left, the delivery port 701 of nozzle 70 is closed in the presence of 60.
So after having used, due to having valve 5 in head cap 4, so that it may at once close nozzle 70, it is to avoid in head cap 40
Remaining emulsion liquid and contacting external air and influence to use.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of the technology of the present invention principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
Also should be regarded as protection scope of the present invention.
