Abstract
The utility model discloses a diaphragm, diaphragm's outer fringe is equipped with the sealing ring, the upper and lower both sides of sealing ring all are provided with protruding stem, protruding stem be the ring form and with the sealing ring sets up with one heart, diaphragm's material is mountain path rubber. The application provides a diaphragm, the protruding stem that sets up on the sealing ring can and the pump body between form labyrinth clearance, sealing performance is good, compresses tightly just can play fine sealed effect with very little strength.
Description
Technical Field
The utility model relates to a diaphragm pump technical field, concretely relates to diaphragm.
Background
The diaphragm pump works by changing the volume of the working chamber through the back-and-forth movement of the diaphragm so as to suck and discharge liquid. Common diaphragm in the existing market sets up the sealing ring at the outer fringe of diaphragm to diaphragm and pump body sealing connection, but current diaphragm has the sealing performance not good, takes place the problem of seepage easily.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a diaphragm that sealing performance is good.
In order to achieve the above object, the utility model provides a following technical scheme:
a sealing ring is arranged at the outer edge of the diaphragm, and convex stems are arranged on the upper side and the lower side of the sealing ring.
Further, the convex stem is annular and is arranged concentrically with the sealing ring.
Furthermore, the diaphragm is made of mountain road rubber.
Further, the radial cross section of the sealing ring is oblong.
Further, the inner edge and the outer edge of the top of the convex stem are both provided with arc chamfers.
According to the above technical solution, the utility model has the advantages that:
compared with the prior art, the utility model discloses in, the protruding stem that sets up on the sealing ring can and form labyrinth clearance between the pump body, sealing performance is good, and can not arouse that whole diaphragm warp, compress tightly with very little strength and just can play fine sealed effect, prevent oil leakage, gas leakage, leak and the invasion of external environment's medium and dust, if meet the casing and break and can also play sealed effect strong adaptability, can accomplish not leak when sealed as quiet, be used for can accomplish almost not to leak the performance unchangeable when the past counter motion, be the interior ideal seal structure of pneumatic electric diaphragm pump.
In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages. The present invention will be described in further detail with reference to the drawings.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts. In the drawings:
fig. 1 is a schematic perspective view of the present invention.
Fig. 2 is a schematic top view of the present invention.
Fig. 3 is a schematic sectional view of the front view of the present invention.
Fig. 4 is an enlarged schematic view of a structure at a in fig. 3.
Labeled as: sealing ring 1, convex stem 2, installation through hole 3, flexion 4.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 4, like the diaphragm that fig. 1, fig. 2, fig. 3, fig. 4 show, the diaphragm is discoid, and the diaphragm material is mountain path rubber, and the outer fringe of diaphragm is equipped with sealing ring 1, and the radial cross-section of sealing ring 1 is the long circle, the upper and lower both sides of sealing ring 1 all are provided with protruding stem 2, protruding stem 2 be the ring form and with sealing ring 1 sets up with one heart, the inner edge and the outer fringe at the top of protruding stem 2 all are provided with the circular arc chamfer, and the center of diaphragm is provided with installation through-hole 3, and the radial middle part of diaphragm is provided with flexion 4.
As shown in figure 1 and figure 4, the convex stem 2 arranged on the sealing ring 1 can form a labyrinth gap with the pump body, the sealing performance is good, the deformation of the whole diaphragm can not be caused, the sealing effect can be well achieved by pressing with small force, the leakage of oil, gas and water and the invasion of medium and dust of the external environment can be prevented, the adaptability of the sealing effect can be achieved if the shell is broken, the static sealing can be achieved without leakage, the leakage performance can be almost achieved without changing when the static sealing is used for reverse movement, and the sealing structure is the ideal sealing structure in the pneumatic electric diaphragm pump.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
