Currently, being mainly in the market diaphragm pump for the topping-up pump type on board-washing machine, structure working principle is to rely on
One agitating back and forth for diaphragm and change swept volume of a single chamber to suck and be discharged liquid, therefore, the pump output terminal mouth of the type
The liquid of output there is the pulse of certain frequency and unstable, simultaneously as the washing lotion being applied on board-washing machine is several Jie
The mixed solution of matter is easy to generate bubble in the pipeline of hose and board-washing head, this just leads during drawing liquid
It causes liquid when entering board-washing head fluid injection by hose, splashing liquid and the discontinuous problem of fluid injection occurs, so as to cause each micro-
Reservoir quantity in plate hole has differences, and influences the experiment effect of microwell plate, in addition, the liquid splashed out can flow into other holes, makes
It is ineffective at board-washing, influence the interpretation result of subsequent experimental.
Summary of the invention
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of fluid path buffering applied to board-washing machine
Damper, effect is the pressure pulse that can absorb and buffer fluid path output, and can obstruct and reduce bubble formation in pipeline,
To solve the problems, such as that splashing liquid and fluid injection are discontinuous when board-washing head fluid injection, board-washing machine washing plate effect is promoted.
The purpose of this utility model is achieved through the following technical solutions: a kind of fluid path buffer damping applied to board-washing machine
Device, including pedestal, sealing plate, pedestal and sealing plate, which link together, forms the damper body with airtight cavity, damper body
One damping baffle of inside setting, leaving certain gaps uncovered by the economic plan between damping baffle and the top of damper body, damping baffle is by damper
Body interior cavity is divided into admission chamber and out sap cavity, and admission chamber is provided with inlet, and sap cavity is provided with liquid outlet out, damping baffle with
Fluid passage is formed between damper body, the fluid passage is connected to inlet, liquid outlet.
Preferably, the inlet is opened in damper body admission chamber side, and the inlet opens up position lower than resistance
Gap position between Buddhist nun's baffle and damper body.
Preferably, the inlet is equipped with feed liquor pipe fitting, and feed liquor is equipped between the feed liquor pipe fitting and inlet
Sealing ring.
Preferably, the liquid outlet opens up position and goes out sap cavity bottom in damper body.
Preferably, the liquid outlet is equipped with liquid outlet joint, is equipped with liquid between the liquid outlet joint and liquid outlet
Sealing ring.
Compared with prior art, a kind of fluid path isolation damper applied to board-washing machine provided by the utility model, has
Beneficial effect is to initially enter admission chamber by the liquid of liquid injection port injection, avoids inside cavity and forms vortex and generate a large amount of bubbles
And be brought directly in liquid outlet flow ipe, while making liquid when admission chamber accumulation is greater than height of baffle plate, lenitively flow
Enter out sap cavity, and form air bag on cavity top, level 2 buffering pressure maintaining accumulation of energy is carried out to fluid pressure, in addition, inlet stream
The bubble that the hydraulic shock entered generates in admission chamber can be blown, without by band because pressure can float after emersion liquid level
Enter to sap cavity out, therefore prevented the generation of a large amount of bubbles, to make constant, soft, bubble-free the liquid of liquid outlet output pressure
Body stream is not in that splashing liquid, fluid injection are discontinuous when carrying out fluid injection by the board-washing head that the liquid of liquid outlet output flows into board-washing machine
Problem.
Detailed description of the invention
Fig. 1 is a kind of fluid path isolation damper structural schematic diagram applied to board-washing machine described in the utility model.
Wherein, 1- pedestal, 2- admission chamber, 3- feed liquor sealing ring, 4- feed liquor pipe fitting, 5- inlet, 6- sealing plate, 7- damping
Baffle, 8- liquid outlet joint, 9- go out liquid sealing ring, 10- liquid outlet, and 11- goes out sap cavity, 12- damper body.
Specific embodiment
For the purpose and effect for the technical characteristics of the utility model being described in detail He being realized, do below in conjunction with attached drawing into one
The description of step: as shown in Figure 1, a kind of fluid path isolation damper applied to board-washing machine, including pedestal 1, sealing plate 6, base
Seat 1 links together with sealing plate 6 forms the damper body 12 for having airtight cavity, one resistance of setting inside damper body 12
Buddhist nun's baffle 7, leaving certain gaps uncovered by the economic plan between damping baffle 7 and the top of damper body 12, damping baffle 7 will be inside damper bodies 12
Cavity is divided into admission chamber 2 and out sap cavity 11, and admission chamber 2 is provided with inlet 5, and sap cavity 11 is provided with liquid outlet 10, damping baffle 7 out
Fluid passage is formed between damper body 12, the fluid passage is connected to inlet 5, liquid outlet 10.
Preferably, the inlet 5 is opened in 12 side of damper body, and the inlet 5 opens up position lower than damping
Gap position between baffle 7 and damper body 12.
Preferably, the inlet 5 is equipped with feed liquor pipe fitting 4, is equipped between the feed liquor pipe fitting 4 and inlet 5
Feed liquor sealing ring 3.
Preferably, the liquid outlet 10 opens up position in 12 bottom of damper body.
Preferably, the liquid outlet 10 is equipped with liquid outlet joint 8, sets between the liquid outlet joint 8 and liquid outlet 10
There is liquid sealing ring 9 out.
Described is a kind of applied to its course of work of the fluid path isolation damper of board-washing machine are as follows: liquid is injected by inlet 5
Admission chamber 2, and impact in the damper body 12 and damping baffle 7 of 2 side of admission chamber, realize the buffering to liquid pulse, together
When avoid in the cavity portion formed vortex and generate a large amount of bubbles, the hydraulic shock flowed by inlet 5 produces in admission chamber 2
The liquid of raw bubble and injection per se with bubble because pressure can float, can blow after emersion liquid level, without
It is brought into out sap cavity 11, with the injection of liquid, the liquid of admission chamber 2 is constantly accumulated, and gradually mitigated in accumulation,
Bubble is discharged, when accumulation of fluid height is greater than 7 height of damping baffle, liquid lenitively flows into out sap cavity 11 from admission chamber 2, and
An air bag is formed on cavity top, this air bag is played during liquid flows into the secondary buffer of liquid and pressure maintaining storage
Can effect, the generation of a large amount of bubbles is avoided, so that the liquid that liquid outlet 10 exports is that one section of pressure is constant, soft, nothing
The liquid flow of bubble, therefore, when carrying out fluid injection by the board-washing head that the liquid that liquid outlet 10 exports flows into board-washing machine, fluid injection effect
More evenly, soft and bubble-free improves the fluid injection of board-washing machine to solve the problems, such as that board-washing machine splashing liquid and fluid injection are discontinuous
Performance improves board-washing effect.
