Also corresponding larger.In the prior art, such device has the following deficiencies: 1, causes pipeline vibration big;2, inhalation flow indicates wave
Dynamic big and registration is inaccurate;3, pump operation noise is big, accelerates the damage of suction metering valve, seriously affects the service life of diaphragm pump.
Summary of the invention
The technical problem to be solved by the utility model is to overcoming the deficiencies of the prior art and provide a kind of reduction pipeline vibration
Diaphragm pump intake buffer unit that is dynamic, reducing operation noise, the service life for extending suction metering valve and diaphragm pump.
The utility model solve its technical problem the technical solution adopted is that: the diaphragm pump intake buffer unit, feature
It is: including suction line and diaphragm pump head, additional ports buffer on the suction line, the lower part of the entry buffer
Suction line is connected by threeway, is equipped with rubber pneumatic bag in entry buffer.
The utility model adds buffer on suction line, the built-in rubber air bag especially on suction line, is formed
Pneumatic cushion is mainly used for the absorption of flow Yu pressure fluctuation peak value, reduces the vibration and noise of pipeline, guarantees suction line
The flow of line indicates accuracy;Meanwhile medium soakage is constant in pumping, and pump operation noise reduces, the service life of pump is extended,
Reduce the replacement of maintenance capacity and accessory.Using the buffer of built-in airbag type, air bag replacement is convenient, and inflation is simple, simple real
With.
The threeway two-port is connected to suction line, and mouth of pipe is connected to entry buffer lower part, and is equipped at mouth of pipe
Pipe flange.
The entry buffer includes seamless steel pipe and support frame, and seamless steel pipe is vertically arranged, passes through flanged joint three
It is logical, it is equipped with laterally fixed support frame in seamless steel pipe, places rubber pneumatic bag on support frame.
Blind flange is equipped at the top of the seamless steel pipe, rubber pneumatic bag is arranged between blind flange and support frame.
The support frame is netted setting, and mesh is less than the minimum diameter after rubber pneumatic bag is deflated.
Compared with prior art, beneficial effect possessed by the utility model is: the utility model increases on suction line
If buffer, the built-in rubber air bag especially on suction line forms pneumatic cushion, is mainly used for flow and pressure arteries and veins
The absorption of dynamic peak value, reduces the vibration and noise of pipeline, guarantees the flow instruction accuracy of suction line;Meanwhile medium in pumping
Soakage is constant, and pump operation noise reduces, and extends the service life of pump, reduces the replacement of maintenance capacity and accessory.Using interior
The buffer of gasbag-type is set, air bag replacement is convenient, and inflation is simple, simple and practical.
Detailed description of the invention
Fig. 1 is diaphragm pump intake buffer unit structure schematic diagram.
Fig. 2 is entry buffer structural schematic diagram.
Wherein, 1, suction line 2, threeway 3, pipe flange 4, seamless steel pipe 5, blind flange 6, rubber pneumatic bag 7, branch
Support 8, outlet line 9, entry buffer 10, output port buffer 11, diaphragm pump head.
Specific embodiment
Fig. 1 ~ 2 are the most preferred embodiments of the utility model, and 1 ~ 2 pair of the utility model is done furtherly with reference to the accompanying drawing
It is bright.
Referring to attached drawing 1 ~ 2: diaphragm pump intake buffer unit, including suction line 1 and diaphragm pump head 11, on suction line 1
The lower part of additional ports buffer 9 and output port buffer 10, entry buffer 9 connects suction line 1 by threeway 2, and entrance is slow
It rushes and is equipped with rubber pneumatic bag 6 in device 9.
The two-port of threeway 2 is connected to suction line 1, and mouth of pipe is connected to 9 lower part of entry buffer, and pipe is equipped at mouth of pipe
Flange 3.Entry buffer 9 includes seamless steel pipe 4 and support frame 7, and seamless steel pipe 4 is vertically arranged, by flanged joint threeway 2,
It is equipped with laterally fixed support frame 7 in seamless steel pipe 4, places rubber pneumatic bag 6 on support frame 7.Blind is equipped at the top of seamless steel pipe 4
Orchid 5, rubber pneumatic bag 6 are arranged between blind flange 5 and support frame 7.Support frame 7 is netted setting, and mesh is less than rubber pneumatic bag 6 and puts
Minimum diameter after gas.
Working principle and the course of work: buffer is arranged in the utility model on suction line 1, especially in suction line
Built-in rubber air bag 6 is added on 1, forms pneumatic cushion, is mainly used for the absorption of flow Yu pressure fluctuation peak value, reduces pipe
The vibration and noise on road guarantees the flow instruction accuracy of suction line;Meanwhile medium soakage is constant in pumping, pump operation is made an uproar
Sound reduces, and extends the service life of pump, reduces the replacement of maintenance capacity and accessory.Using the buffer of built-in airbag type, gas
Capsule replacement is convenient, and inflation is simple, simple and practical.
Specifically, suction line 1 is the suction line of pump, pipe flange is welded in suction line plus threeway 2, tee branch
