Abstract
The invention relates to the technical field of valve bodies and in particular relates to a diaphragm type check valve. The diaphragm type check valve comprises a cylindrical valve body with a flange, wherein the valve body is internally provided with a separation plate vertical to the axis of the valve body; a water through hole is formed in the central part of the separation plate; the central position of one side of the separation plate is detachably provided with an elastic diaphragm with the diameter being greater than that of the water through hole; a water through gap is formed between the diaphragm and the separation plate. When water flow flows into the valve body from one side which is not provided with the diaphragm of the separation plate, the diaphragm is bulged towards one side of the water flow direction under the action of water flow pressure, and the water flow can normally pass through the valve body through the water through hole and the water through gap; when the water flow flows into the valve body from one side provided with the diaphragm of the separation plate, the diaphragm is bulged towards one side of the water flow direction under the action of the water flow pressure, and the bulged diaphragm blocks the water through hole, so that the water flow cannot normally pass through the valve body through the water through hole. The check valve is simple in structure; the manufacturing cost and the maintenance cost are lower than those of a traditional check valve.
Description
Technical field
The present invention relates to valve body technical field, particularly a kind of diaphragm type one-way valve.
Background technique
One-way valve is that fluid can only flow along water intake, and water outlet medium but cannot reflux, and is commonly called as one-way valve.One-way valve is also known as safety check or check valve.For preventing oil stream reverse flow in hydraulic system, or for preventing pressurized air reverse flow in pneumatic system.One-way valve has straight-through type and right-angle type two kinds.Straight check valve is arranged on pipeline with being threaded.Angle check valve is threaded, board-like connection and Flange joint three kinds of forms.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of diaphragm type one-way valve is provided.
For solving the problem, the invention provides following technological scheme:
A kind of diaphragm type one-way valve, comprises the valve body of flanged (FLGD) circular tube shaped, is provided with the dividing plate perpendicular to valve body shaft axis in described valve body; The central part of described dividing plate is provided with water passage hole; The central position of described dividing plate side is removably provided with diameter and is greater than water passage hole diameter and has flexible barrier film; Water space was provided with between described barrier film and dividing plate.
Further, the side of described dividing plate is interval with four boss along the circumferencial direction of the edge of water passage hole.
Further, described boss is arc cam.
Further, each described boss is equipped with a threaded counterbore.
Further, the side described dividing plate having boss is provided with ring pressing plate by hold-down bolt.
Further, described barrier film is installed on side dividing plate with boss, and the edge clamping of barrier film is located between boss and ring pressing plate.
Further, the edge of described barrier film offers through hole; Described hold-down bolt is connected with the counterbore on boss with barrier film through pressing plate successively.
Further, describedly the region that water space is septum plane, the end face of diaphragm plane and adjacent two boss surrounds is crossed.
Beneficial effect: a kind of diaphragm type one-way valve of the present invention, when the side that current do not install barrier film from dividing plate flows to valve body, water flow pressure makes barrier film heave to this water (flow) direction side, and current by water passage hole and can cross water space normal through valve body; When current from dividing plate install septate side flow to valve body time, water flow pressure makes barrier film heave to this water (flow) direction side, and water passage hole is blocked by the barrier film heaved, and current cannot by water passage hole normal through valve body.This one-way valve structures is simple, and manufacture cost compares traditional one-way valve with maintenance cost lower.

Embodiment
Below in conjunction with Figure of description and embodiment, specific embodiments of the invention are described in further detail:
Referring to figs. 1 through a kind of diaphragm type one-way valve shown in Fig. 5, comprise the valve body 1 of flanged (FLGD) circular tube shaped, in described valve body 1, be provided with the dividing plate 2 perpendicular to valve body 1 shaft axis; The central part of described dividing plate 2 is provided with water passage hole 7; The central position of described dividing plate 2 side is removably provided with diameter and is greater than water passage hole 7 diameter and has flexible barrier film 3; Water space 8 was provided with between described barrier film 3 and dividing plate 2.
The side of described dividing plate 2 is interval with four boss 4 along the circumferencial direction of the edge of water passage hole 7.
Described boss 4 is arc cam 4.
Each described boss 4 is equipped with a threaded counterbore.
The side described dividing plate 2 with boss 4 is provided with ring pressing plate 5 by hold-down bolt 6.
Described barrier film 3 is installed on side dividing plate 2 with boss 4, and the edge clamping of barrier film 3 is located between boss 4 and ring pressing plate 5.
The edge of described barrier film 3 offers through hole; Described hold-down bolt 6 is connected with the counterbore on boss 4 with barrier film 3 through pressing plate 5 successively.
Describedly cross the region that water space 8 is dividing plate 2 plane, the end face of barrier film 3 plane and adjacent two boss 4 surrounds.
A kind of diaphragm type one-way valve of the present invention, when the side that current do not install barrier film 3 from dividing plate 2 flows to valve body 1, water flow pressure makes barrier film 3 heave to this water (flow) direction side, and current by water passage hole 7 and can cross water space 8 normal through valve body 1; When current flow to valve body 1 from the side that dividing plate 2 is provided with barrier film 3, water flow pressure makes barrier film 3 heave to this water (flow) direction side, and water passage hole 7 is blocked by the barrier film 3 heaved, and current cannot by water passage hole 7 normal through valve body 1.This one-way valve structures is simple, and manufacture cost compares traditional one-way valve with maintenance cost lower.
The above, it is only preferred embodiment of the present invention, not any restriction is made to technical scope of the present invention, thus every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalent variations and modification, all still belong in the scope of technological scheme of the present invention.
