Abstract
The utility model proposes a kind of plate valves and diaphragm pump for diaphragm pump, and the plate valve for diaphragm pump includes: valve body, and the valve body has central through hole, and the central through hole includes main body hole section and the undergauge hole section below the main body hole section；Flap, the flap are pivotally arranged on the valve body and are adapted with the main body hole section, and the flap is for opening and closing the central through hole.Plate valve according to the present utility model for diaphragm pump, structure is simple, is suitable for large granular materials conveys.
Description
Technical field
A kind of diaphragm pump of plate valve the utility model relates to plate valve for diaphragm pump and with this for diaphragm pump.
Background technique
It in the diaphragm pump course of work, is influenced by pump shaft propulsion, forms high pressure between diaphragm and column, at this time feed end ball valve
It is bonded by pressure with ball seat, composition closing valve.The compression of discharge end ball valve is pushed to move and be moved upwards, and is supported after moving to highest point
Pawl constrains and stops, and material bypasses ball valve after passing through ball seat centre bore, flows out from support claw gap.When pump shaft is promoted to the other end
When, and low pressure is formed, discharge end ball valve is bonded by pressure with ball seat at this time, forms sealing state, feed inlet is then on the contrary, anti-with this
Complex is at working cycles.
Existing pump valve is ball valve, since ball valve needs to place sphere at material circulation to reach sealing function, so
Cause overflow section to greatly reduce, affects the circulation efficiency of entire pump housing pipeline, and because sphere need to be flowed in pipeline middle
Gap of the logical part between pipeline and sphere, so also limiting the maximum gauge of transmission material, it is some special to have influenced
The use of (such as conveying for large granular materials) under environment.
Utility model content
The utility model is intended to solve at least some of the technical problems in related technologies.
For this purpose, a purpose of the utility model is to propose that a kind of structure is simple, suitable for large granular materials conveying
Plate valve for diaphragm pump.
The another object of the utility model is to propose a kind of diaphragm pump of plate valve with this for diaphragm pump.
A kind of plate valve for diaphragm pump according to the present utility model, comprising:
Valve body, the valve body have central through hole, the central through hole include main body hole section and be located at the main body hole section
Following undergauge hole section；
Flap, the flap are pivotally arranged on the valve body and are adapted with the main body hole section, and the flap is used
In the opening and closing central through hole.
Advantageously, the valve body is configured to cylindrical body.
Advantageously, the rotational angle of the flap is 0 °~80 °.
A kind of diaphragm pump according to the present utility model, including the plate valve described in any of the above embodiments for diaphragm pump.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.
Detailed description of the invention
Fig. 1 is according to the schematic diagram of the plate valve for diaphragm pump of the utility model one embodiment, and plate valve is at this time
Closed state；
Fig. 2 is according to the schematic diagram of the plate valve for diaphragm pump of another embodiment of the utility model, and plate valve is at this time
Opening state.
Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
It is described in detail the plate valve according to the present utility model for diaphragm pump with reference to the accompanying drawing.
As depicted in figs. 1 and 2, a kind of plate valve for diaphragm pump according to the present utility model, comprising: valve body 100, flap
200。
Specifically, valve body 100 has central through hole 110, central through hole 110 is including main body hole section 111 and is located at main body
Undergauge hole section 112 below hole section 111.Advantageously, valve body 100 is configured to cylindrical body.
Flap 200 is pivotally arranged on valve body 100 and is adapted with main body hole section 111, and flap 200 is used to open and closes
Close central through hole 110.Advantageously, the rotational angle of flap 200 is 0 °~80 °, i.e., when flap 200 cooperates in main body hole section 111
When interior, the angle between flap 200 and valve body 100 is 0 °；When flap 200 opens central through hole 110, flap 200 and valve body
Maximum angle between 100 is 80 °.
Plate valve according to the present utility model for diaphragm pump, is mounted on the column of diaphragm pump, specific installation and column
End.When diaphragm pump work, when fluid media (medium) during inhalation, the plate valve positioned at the upper end of the column is by pressure considerations, flap
200 because pressure difference closing center through-hole 110 reaches sealing function, positioned at the plate valve of column lower end so forming confined space
Again because of pressure difference, flap 200 opens central through hole, so forming the space of connection, achievees the purpose that flow medium.When being situated between
In matter discharge process, then just on the contrary, achieving the purpose that transmission medium as a circulation.Since plate valve is without similar ball
The object of the influence pipeline flow sectional area of body etc, so the circulation medium of larger particles can be transmitted, and can make pipeline abundant
It utilizes.
