Description
Technical field
The utility model is related to a kind of metering pumps, specifically metering pump pumping diaphragm, belong to pumping diaphragm technical field.
Background technology
Metering pump replaces plunger, diaphragm to realize reciprocatings motion under the action of the drive mechanism using diaphragm, complete liquid suck,
Discharge process.Metering pump is truly realized being isolated between fluid and driving mechanism due to the buffer action of diaphragm in structure.
Conventional metered dose pump pumping diaphragm is formed by mold with glueds joint by rubber layer, tetrafluoro layer, iron core.Since it is with not
It is glued with material, in various acid alkaline environments, rubber layer and tetrafluoro layer are easy aging and aoxidize degumming, 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, so that the deformation of diaphragm flexing is agitated back and forth by plunger, then tie
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
Diaphragm flexing point fatigue rupture.Therefore traditional pumping diaphragm is one very fatal weak link of metering pump, at regular intervals
It must replace, and diaphragm cost is relatively high.
Invention content
In place of the purpose of this utility model is to overcome above-mentioned deficiency, to provide a kind of metering pump pumping diaphragm, pump is enhanced
Membrane structure improves service life.
According to technical solution provided by the utility model, metering pump pumping diaphragm includes pumping diaphragm rubber bodies and metal insert, spy
Sign is：Metal insert front end is equipped with groove structure and boss structure successively, and it is embedding that the center back ends of pumping diaphragm rubber bodies is inlaid in metal
On the groove structure and boss structure of part, to which pumping diaphragm rubber bodies and metal insert be linked into an integrated entity；Pumping diaphragm rubber bodies front end
Surface is equipped with pumping diaphragm chamber, and pumping diaphragm intracavitary is equipped with the blocking 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 blocking 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 utility model has the following advantages：
The utility model is simple in structure, compact, reasonable, enhances pumping diaphragm structure, and pumping diaphragm rubber bodies are connected with metal insert
It is closer, it is not easy to degumming phenomenon occur；Pumping diaphragm rubber bodies improve pumping diaphragm cavity configuration, improve service life.
Description of the drawings
Fig. 1 is the utility model front view.
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 implementation mode
The utility model will be further described in conjunction with the embodiment in attached drawing below：
As shown in Figure 1, the utility model includes mainly pumping diaphragm rubber bodies 1 and metal insert 2,2 front end of metal insert is successively
Equipped with groove structure 4 and boss structure 3, the center back ends of pumping diaphragm rubber bodies 1 is inlaid in the groove structure 4 of metal insert 2 and convex
In platform structure 3, 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 and metal insert 2 connect closer, it is not easy to degumming phenomenon occur.
2 rear end of the 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 blocking ring body 8 of multiple protrusions is equipped in pumping diaphragm chamber 7, multiple
Blocking ring body 8 is circumferentially uniformly distributed, and blocking ring body 8 can improve stress when 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 utility model is simple in structure, compact, reasonable, enhances pumping diaphragm structure, and pumping diaphragm rubber bodies 1 are connected with metal insert
It is closer, it is not easy to degumming phenomenon occur；Pumping diaphragm rubber bodies improve pumping diaphragm cavity configuration, improve service life.
