Abstract
The utility model discloses a hydraulic end of a high-temperature diaphragm metering pump, which is additionally provided with a flow through body and a middle pipeline. The flow through body is provided with three openings, every two openings are communicated, a suction valve group and an exhaust valve group are arranged on two of the openings of the flow through body, one end of the middle pipeline is connected with the third opening of the flow through body, the other end of the middle pipeline is connected with one end of a cylinder cover, and the other end of the cylinder cover is sealed. A cooling device is arranged on the middle pipeline. The hydraulic end of the high-temperature diaphragm metering pump has the advantages of being capable of reducing sizes of a cylinder body and the cylinder cover, saving cost and ensuring a diaphragm to have long enough service life. A sealing assembly and a plunger work at normal temperature so that service life of the sealing assembly and the plunger can be effectively prolonged. A heat source is far away form transmission box components of the pump, thereby reducing influence of the heat source on the transmission box components. Large parts of the cylinder body, the cylinder cover and the like can be used universally on conventional pumps, thereby facilitating standardization, serialization and universalization of the product.
Description
Technical field
The utility model relates to the technological improvement of high temperature diaphragm metering pump fluid end, belongs to pump hydraulics field.
Background technique
Traditional metering diaphragm pump hydraulic end structure is as shown in Figure 1; Comprise medium import 1, inlet tube 2, inhale valve group 3, cylinder cap 4, cylinder body 5, valve group 6, outer pipe 7, media outlet 8, medium import 1 is connected with inlet tube 2 through flange, and inlet tube 2 is connected with suction valve group 3 again; Suction valve group 3 and valve group 6 are installed in the two ends of cylinder cap 4; Be provided with the passage that medium passes through in the cylinder cap, outer pipe 7 one ends are connected with valve group 6, and the other end is connected with media outlet 8 through flange.Be provided with barrier film 9 between cylinder cap 4 and the cylinder body 5, cylinder body 5 is provided with plunger 10 and black box 11.As can beappreciated from fig. 1, the existing structure flowing medium directly contacts with barrier film, and after medium temperature reached more than 200 degree, conventional PTFE barrier film can not use.Generally just use metal diaphragm.But the metal diaphragm elastic deformation amount is little, and under same parameter, cylinder body and cylinder cap size just become very big, increase cost, and can not be general with conventional structure, is unfavorable for " three change ".In addition, high temperature media directly contacts with cylinder cap, and high temperature directly passes to the pump drive case through cylinder cap, cylinder body, causes the transmission case temperature to raise, and influences the driving component operation.Black box is contained in the cylinder body, and it also moves under the condition of high temperature, and this will influence the life-span of black box.
The model utility content
To the above-mentioned deficiency that existing technology exists, the purpose of the utility model provides a kind of high temperature diaphragm metering pump fluid end with high temperature media that flows and barrier film isolation.
The technological scheme of the utility model is achieved in that a kind of high temperature diaphragm metering pump fluid end; Comprise medium import, inlet tube, suction valve group, cylinder cap, cylinder body, valve group, outer pipe and media outlet; The medium import is connected with suction valve group through inlet tube; The valve group is connected with media outlet through outer pipe, is provided with barrier film between cylinder cap and the cylinder body.Its improvement is: this fluid end had additional fluid and intermediate duct; Cross fluid and have three openings that are communicated with in twos; Inhale on wherein two openings that valve group and valve group be installed in fluid; The 3rd opening of intermediate duct one end and mistake fluid is connected, and the intermediate duct the other end is connected with cylinder cap one end, the sealing of the cylinder cap the other end.
Said intermediate duct is provided with cooling unit.
Further, the said mistake in three openings of fluid, wherein two over against, the 3rd opening is perpendicular to the line of other two openings; Inhale valve group and valve group be installed in two of fluids over against opening on.
Compared with prior art, the utlity model has following advantage:
One, dwindles the size of cylinder body and cylinder cap, save cost, and guarantee that barrier film has enough life-spans.
Two, can adopt two barrier film warning structures, the assurance medium is never revealed.
Three, black box and plunger move at normal temperatures, effectively prolong its working life.
Four, thermal source reduces the influence of thermal source to the transmission case parts away from the pump drive box part.
Five, heavy parts such as cylinder body, cylinder cap and conventional pumps are general, help " three change " of product.
The utility model has better technology capability and reliability, maintainability, safety and human factors under the prerequisite that guarantees the power end reliability, solved the above-mentioned deficiency of existing technology, has higher utility.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 2; On scheming, can find out; The utility model high temperature diaphragm metering pump fluid end; Equally comprise medium import 1, inlet tube 2, inhale valve group 3, cylinder cap 4, cylinder body 5, valve group 6, outer pipe 7 and media outlet 8 with existing technology, medium import 1 is connected with suction valve group 3 through inlet tube 2, and valve group 6 is connected with media outlet 8 through outer pipe 7.Be provided with barrier film 9 between cylinder cap 4 and the cylinder body 5, cylinder body 5 is provided with plunger 10 and black box 11.The utility model improves and is: this fluid end had additional fluid 12 and intermediate duct 13, and intermediate duct 13 is provided with cooling unit 14.Cross fluid and have three openings that are communicated with in twos, inhale on wherein two openings that valve group and valve group be installed in fluid, the 3rd opening of intermediate duct one end and mistake fluid is connected, and the intermediate duct the other end is connected with cylinder cap one end, and the cylinder cap the other end seals.
Further, the said mistake in three openings of fluid, wherein two over against, the 3rd opening is perpendicular to the line of other two openings; Inhale valve group and valve group be installed in two of fluids over against opening on.
The utility model will be inhaled the valve group by mistake fluid replacement cylinder cap and be connected with the valve group; Originally with inhale the cylinder cap two ends that valve group, valve group be connected in a wherein end be connected with intermediate duct; The other end sealing gets final product, and promptly through intermediate duct cylinder cap and media flow side (this side comprised fluid, inhales valve group, valve group, inlet tube, outer pipe and flange etc.) is separated.In the pump operation, the medium that cylinder cap reaches in the intermediate duct that links to each other can not flow away basically.The intermediate duct that links to each other is outside equipped with cooling unit; Cut off the heat that high temperature media passes in the fluid; Thereby make high temperature media a suction valve group, valve group, cross in fluid, inlet tube, outer pipe and the flange and flow at far-end; The medium that ensures the contact barrier film is a normal temperature, reaches the purpose that can use PTFE material barrier film.
The foregoing description of the utility model only is to give an example for what explanation the utility model was done, and is not to be the qualification to the mode of execution of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation and changes.Here can't give exhaustive to all mode of executions.Conspicuous variation that every technological scheme that belongs to the utility model is amplified out or change still are in the row of the protection domain of the utility model.
