Abstract
The utility model discloses a membrane type one-way valve comprising a valve body, the two sides of the valve body are provided with a water inlet and a water outlet respectively, an aluminum base is installed inside the valve body and is provided with a valve element, a membrane is installed between the aluminum base and the valve element, a strip-shaped magnet is installed inside the valve element, the portion, at the water outlet end, of the valve body is internally provided with a first baffle and a second baffle, the top end of the first baffle is movably connected with the valve body, a spring is installed between the first baffle and the valve body, the bottom end of the second baffle is movably connected with the valve body, a spring is installed between the second baffle and the valve body, and the bottom end of the first baffle is in contact connection with the top end of the second baffle. The membrane type one-way valve is simple in structure and convenient to install; due to the arrangement of the strip-shaped magnet, the valve element and the aluminum base can be connected tightly, limitation from the installation angle and normal pressure is avoided, the one-way continuity of the one-way valve is improved, backflow is avoided, and practicability of the one-way valve is improved.
Description
Technical field
The utility model relates to a kind of one-way valve, relates in particular to 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.On compressor air-discharging pipeline, usually use one-way valve, but the one-way valve using is at present subject to the automatic closure that the relation of setting angle restriction and backpressure size affects valve, thereby affect one-way valve, normally uses on compressor air-discharging pipeline.
Model utility content
The purpose of this utility model is to provide a kind of diaphragm type one-way valve, it is simple in structure, easy for installation, the setting of bar magnet can make spool and aluminium seat closely be connected to make its restriction that is not subject to setting angle and is sent to pressure, greatly improve the unidirectional general character of one-way valve and without backflow, thereby improved the practicability of one-way valve.
In order to achieve the above object, the technical solution of the utility model is:
A diaphragm type one-way valve, comprises valve body, and described valve body both sides offer respectively water intake, water outlet, aluminium seat is installed in described valve body, on described aluminium seat, spool is installed, between described aluminium seat and spool, diaphragm is installed, in described spool, bar magnet is installed; In the valve body of described water outlet end, be separately installed with the first baffle plate, second baffle, described the first baffle plate top and valve body are movably connected, and between described the first baffle plate and valve body, spring is installed, described second baffle bottom and valve body are movably connected, and between described second baffle and valve body, spring is installed, described the first baffle plate bottom contacts with second baffle top and is connected.
Spherical filter screen is installed on described spool.
On described aluminium seat, anticollison block is installed.
In described valve body, sealing plug is installed, the bottom surface of described sealing plug is provided with projection, filter screen baffle plate is installed between described sealing plug and spool, on described filter screen baffle plate, offer the groove being used in conjunction with projection, and the length of described projection is greater than the nozzle diameter of water intake.
The beneficial effects of the utility model are: a kind of diaphragm type one-way valve, it is simple in structure, easy for installation, the setting of bar magnet can make spool and aluminium seat closely be connected to make its restriction that is not subject to setting angle and is sent to pressure, greatly improve the unidirectional general character of one-way valve and without backflow, thereby improved the practicability of one-way valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
A kind of diaphragm type one-way valve as shown in Figure 1, comprise valve body 1, described valve body 1 both sides offer respectively water intake 8, water outlet 7, in described valve body 1, aluminium seat 6 is installed, on described aluminium seat 6, spool 3 is installed, between described aluminium seat 6 and spool 3, diaphragm 5 is installed, in described spool 3, bar magnet 4 is installed.Spherical filter screen 2 is installed on described spool 3.On described aluminium seat 6, anticollison block 15 is installed.
In the valve body 1 of described water outlet 7 ends, be separately installed with the first baffle plate 9, second baffle 10, described the first baffle plate 9 tops and valve body 1 are movably connected, and between described the first baffle plate 9 and valve body 1, spring 11 is installed, described second baffle 10 bottoms and valve body 1 are movably connected, and between described second baffle 10 and valve body 1, spring 11 is installed, described the first baffle plate 9 bottoms contact with second baffle 10 tops and are connected.
In described valve body 1, sealing plug 14 is installed, the bottom surface of described sealing plug 14 is provided with projection 13, between described sealing plug 14 and spool 3, filter screen baffle plate 12 is installed, on described filter screen baffle plate 12, offer the groove 15 being used in conjunction with projection 13, and the length of described projection 13 is greater than the nozzle diameter of water intake 8.
Diaphragm type one-way valve described in the present embodiment in use liquid opens by spool 3 effect that diaphragm 5 reaches conducting by water intake 8.When water intake 8 no liquid flow to, the liquid of outlet end 7 can reflux during abrupt pressure reduction, but diaphragm 5 plays good inhibition, can prevent that water outlet end from refluxing.On diaphragm 5, there is clad material, can play good seal action.When occurring to reflux, making used time bar magnet 4 can reflux from blocking-up by absorption diaphragm 5.Arranging of the first baffle plate 9, second baffle 10 increased the way flow of the liquid general character, anti-backflow.Sealing plug 14 the further way flow general character that has guaranteed liquid is set.
A kind of diaphragm type one-way valve of the present embodiment, it is simple in structure, easy for installation, and the setting of bar magnet can make spool and aluminium seat closely be connected to make its restriction that is not subject to setting angle and is sent to pressure, greatly improve the unidirectional general character of one-way valve and without backflow, thereby improved the practicability of one-way valve.
