Description
Technical field
The present invention relates to a kind of metering pumps, specifically metering pump pumping diaphragm, belong to pumping diaphragm technical field.
Background technology
Metering pump utilizes diaphragm to substitute plunger, and diaphragm is realized under driving mechanism effect and moved back and forth, the sucking of completion liquid,
Discharge process.Metering pump is truly realized isolating between fluid and driving mechanism due to the buffer action of diaphragm in structure.
Conventional metered dose pump pumping diaphragm is formed by rubber layer, tetrafluoro layer, iron core by mold with glueds joint.Since it is with not
It is glued with material, in various acid alkaline environments, rubber layer and the easy aging oxidation degumming of tetrafluoro layer, iron core and rubber
Layer is also easy to degumming.Traditional Electromagnetic diaphragm metering pump all compresses sealing side using by pump head and pump head connecting seat edge simultaneously
Formula（Face seals）, pump head is become into an airtight cavity, the deformation of diaphragm flexing is continuously back and forth made to agitate back and forth by plunger, then is tied
Inlet and outlet metering pump is closed to open and close to realize the cyclic process for inhaling night and drain.Exactly such sealing means easily cause
The point fatigue rupture of diaphragm flexing.Therefore traditional pumping diaphragm is one very fatal weak link of metering pump, at regular intervals
It must replace, and diaphragm cost is higher.
The content of the invention
It is an object of the present invention to overcome the above deficiencies, so as to provide a kind of metering pump pumping diaphragm, enhances pumping diaphragm knot
Structure improves service life.
According to technical solution provided by the invention, metering pump pumping diaphragm includes pumping diaphragm rubber bodies and metal insert, it is characterized in that：
Metal insert front end is equipped with groove structure and boss structure successively, and the center back end of pumping diaphragm rubber bodies is inlaid in the recessed of metal insert
In slot structure and boss structure, so as to which pumping diaphragm rubber bodies and metal insert be linked into an integrated entity；Pumping diaphragm rubber bodies front-end surface is set
There is pumping diaphragm chamber, pumping diaphragm intracavitary is equipped with the stop ring body of multiple protrusions, and pumping diaphragm rubber bodies edge is equipped with ring body portion.
Further, metal insert rear end is equipped with thread segment.
Further, multiple stop ring bodies are circumferentially uniformly distributed.
Further, pumping diaphragm rubber bodies are located at the thickness of pumping diaphragm chamber position less than ring body portion thickness.
Compared with the prior art the present invention has the following advantages：
The invention has the advantages of simple structure, compactness and reasonable structure, enhances pumping diaphragm structure, pumping diaphragm rubber bodies connected with metal insert it is closer, no
Degumming phenomenon easily occurs；Pumping diaphragm rubber bodies improve pumping diaphragm cavity configuration, improve service life.

Fig. 1 is front view of the present invention.
Reference sign：1- pumping diaphragms rubber bodies, 2- metal inserts, 3- boss structures, 4- groove structures, 5- thread segments,
6- ring body portions, 7- pumping diaphragms chamber, 8- stop ring body.
Specific embodiment
The present invention will be further described with reference to the embodiment in attached drawing below：
As shown in Figure 1, the invention mainly comprises pumping diaphragm rubber bodies 1 and metal insert 2,2 front end of metal insert is equipped with groove successively
Structure 4 and boss structure 3, the center back end of pumping diaphragm rubber bodies 1 are inlaid in the groove structure 4 of metal insert 2 and boss structure 3
On, so as to which pumping diaphragm rubber bodies 1 and metal insert 2 be linked into an integrated entity.Groove structure 4 and boss structure 3 are so that pumping diaphragm rubber bodies 1
It is connected with metal insert 2 closer, it is not easy to degumming phenomenon occur.
2 rear end of metal insert is equipped with thread segment 5, and metal insert 2 is connected to by thread segment 5 in metering pump.
1 front-end surface of pumping diaphragm rubber bodies is equipped with pumping diaphragm chamber 7, and the stop ring body 8 of multiple protrusions is equipped in pumping diaphragm chamber 7, multiple
Stop that ring body 8 is circumferentially uniformly distributed, stop stress when ring body 8 can improve pumping diaphragm work so that fluid flowing is more suitable
Freely, the service life of pumping diaphragm rubber bodies 1 is improved.1 edge of pumping diaphragm rubber bodies is equipped with ring body portion 6, and pumping diaphragm rubber bodies 1 are located at pumping diaphragm chamber 7
The thickness of position is less than 6 thickness of ring body portion.
The invention has the advantages of simple structure, compactness and reasonable structure, enhances pumping diaphragm structure, and pumping diaphragm rubber bodies 1 connect tighter with metal insert
It is close, it is not easy to degumming phenomenon occur；Pumping diaphragm rubber bodies improve pumping diaphragm cavity configuration, improve service life.
