Problems solved by technology

[0004] However, if the umbrella-shaped valve core is used, there are problems in that the number of parts increases, the assembly operation takes time, and the probability of loss or damage during operation is high.
There is also the problem that the manufacturing cost becomes high
In addition, there is a problem that in order to prevent interference between the diaphragm and the umbrella-shaped valve element in the pump chamber, the pump chamber needs to be enlarged, and it is difficult to reduce the size of the diaphragm pump as a whole.
In addition, there are the following problems, that is, by using a small number of umbrella-shaped valve cores, it is easy to cause failure or the reliability of operation is low; noise during opening and closing operation

Abstract

The present invention provides a diaphragm pump for fluid, which has a small number of components and is easily assembled. The diaphragm pump for fluid is provided with the following components: a diaphragm assembly (5) which comprises the components of: bowl-shaped diaphragms (50) that are respectively opened in an axis direction (L1), a short cylindrical discharge valve diaphragm part (52) which is formed through extending an open edge of the diaphragm (50) to an axial direction (L1), and an orthogonal planar transverse diaphragm part (54) which integrally connects a plurality of diaphragms (50) with equal distance on the circumference; a suction valve diaphragm assembly (2) which comprises the components of: an axially orthogonal planar flat plate part (24), and a plurality of short cylindrical suction valve diaphragms (22) which project from the flat plate part (24) to the other axial direction (L2) with equal distance on the circumference; a middle cover body (3) which is provided with a cylindrical discharging valve seat part (35) that is provided between the diaphragm assembly (5) and the suction valve diaphragm assembly (2) and has a discharge valve diaphragm part (52) that clings to and detachably contacts with an outer circumferential surface; and a circular suction valve seat part (32) which is configured coaxially with the discharging valve seat part (35) and has a suction valve diaphragm (22) that clings to and detachably contacts with the outer circumferential surface.

Description

technical field [0001] The invention relates to a diaphragm pump for fluid. Background technique [0002] As in the document proposed by the inventors of the present application, as a conventional diaphragm pump for fluid, there is known a diaphragm pump for fluid that includes a diaphragm unit integrally formed with a plurality of diaphragms forming a pump chamber, and a plurality of umbrella-shaped valve elements. , The middle cover body (referring to patent document 1) that umbrella-shaped valve core is installed. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2009-41538 [0004] However, if the umbrella-shaped valve core is used, there are problems in that the number of parts increases, the assembly operation takes time, and the probability of loss or damage during operation is high. There is also a problem that the manufacturing cost becomes high. Furthermore, there is a problem that in order to prevent interference between the diaphragm and the umbrella-s...
