Diaphragm metering pump pulsation damper, is installed on transfer pipeline, and at diaphragm metering pump outlet end, including
Tube body, the both ends of the tube body are respectively fixedly connected with the pipe cap to match with the tube body, and the tube body surrounds slow with pipe cap
Rush chamber；The connector for connecting the transfer pipeline is connected on one pipe cap, the connector is hollow structure
So as to be connected inside the buffer chamber and the transfer pipeline.
Preferably, the tube body passes through sealing glue sticking with pipe cap.
Preferably, the tube body and pipe cap are made of PVC-U materials or PPR materials.
Preferably, the pipe cap being connected with the connector is equipped with connecting hole, the connector is close to the pipe
One end of cap is inserted into the connecting hole, and the edge of the connecting hole and the periphery of the connector pass through sealing glue sticking.
Preferably, the connector is the direct connector of internal thread.
Preferably, the nominal diameter of the direct connector of internal thread is 20-40mm, the nominal diameter of the connecting hole and institute
The nominal diameter for stating the direct connector of internal thread matches.
Preferably, the length of the tube body is 200-300mm, nominal diameter 50-100mm.
Compared with prior art, it is with advantageous effect the advantages of the utility model：
Diaphragm metering pump pulsation damper provided by the utility model, only with tube body cheap and easy to get, pipe cap and company
Fitting (such as the direct connector of internal thread) can be made into, simple in structure, be hardly damaged, and making is low with maintenance cost, can effectively disappear
The pressure generated except diaphragm metering pump or flow pulsation.

Specific implementation mode
In the following, the utility model is specifically described by illustrative embodiment.It should be appreciated, however, that not having
In the case of being further discussed below, element, structure and features in an embodiment can also be advantageously incorporated into other implementations
In mode.
In the description of the present invention, it should be noted that term "inner", "outside", "upper", "lower", "front", "rear" etc.
The orientation or positional relationship of instruction is to be merely for convenience of description the utility model and letter based on attached position relationship shown in FIG. 1
Change description, do not indicate or imply the indicated device or element must have a particular orientation, with specific azimuth configuration and
Operation, therefore should not be understood as limiting the present invention.
As shown in Figure 1, the utility model is related to a kind of diaphragm metering pump pulsation damper, it is installed on transfer pipeline 2,
And at 1 outlet end of diaphragm metering pump, including tube body 3, the both ends of tube body 3 are respectively fixedly connected with to match with tube body 3
Pipe cap 4, tube body 3 surround buffer chamber 5 with pipe cap 4；The connector 6 for connecting conveying pipe road 2 is connected on one pipe cap 4,
Connector 6 is hollow structure so as to be connected inside buffer chamber 5 and transfer pipeline 2.In use, the fluid in transfer pipeline 2
It can be flowed into buffer chamber 5 into row buffering by hollow connector 6, make the pressure generated because diaphragm metering pump moves back and forth
Power or flow pulsation become flat, and achieve the effect that eliminate pulsation.
In one embodiment, for tube body 3 with pipe cap 4 by sealing glue sticking, this connection type is simple and effective, and
It can ensure that tube body 3 and the junction of pipe cap 4 seal.It is understood that those skilled in the art can also use other conjunctions
The connection type of reason, such as：Be threadedly coupled, weld etc., as long as tube body 3 and pipe cap 4 can be connected and ensure junction
Sealing.
As depicted in figs. 1 and 2, the pipe cap 4 being connected with connector 6 is equipped with connecting hole 41, and connector 6 is close to pipe cap 4
One end is inserted into connecting hole 41, and the edge of connecting hole 41 is with the periphery of connector 6 by sealing glue sticking.This connection type letter
