Description

Technical Field

[0001] The utility model relates to a high-pressure pump for liquefied gas delivery, in particular to a high-pressure pump for liquefied gas delivery in an application field. Background Art

[0002] The high-pressure pump for liquefied gas transportation is driven by low-pressure gas at the large-area piston end to produce high-pressure fluid at the small-area piston end. It can be used to compress air and other gases. The output air pressure can be adjusted steplessly by the driving air pressure. The existing high-pressure pump for liquid transportation is installed and tightened by the combination of studs and nuts, which is easily affected by external water vapor. Long-term connection will cause rust on the connection.

[0003] In order to solve the problem of difficult disassembly, a liquefied gas transmission high-pressure pump in the market adopts a portable disassembly and assembly design, which has a certain market share.

[0004] During installation, the existing pneumatic booster pump needs to be installed and tightened by the cooperation of studs and nuts, but the connection between the studs and nuts is exposed to the outside and is easily affected by external moisture. Long-term connection will cause rust at the connection, making subsequent disassembly more difficult. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the liquid delivery high-pressure pump is installed and fastened by the cooperation of studs and nuts, which is easily affected by external moisture, and long-term connection will cause rust on the connection.

[0006] In order to solve the above problems, the utility model provides a high-pressure pump for liquefied gas transportation, including a high-pressure pump body, a mounting base fixedly connected to the bottom end of the high-pressure pump body, connecting plates symmetrically fixedly connected to both ends of the mounting base, screw holes are drilled on the connecting plates, bolts are threadedly connected to the screw holes, a groove is drilled on the mounting base directly above the connecting plate, a baffle is slidably connected to the groove, and the baffle is engaged with the connecting plate, and a baffle cover is rotatably connected to one end of the baffle close to the connecting plate through a rotating shaft.

[0007] In the above-mentioned high-pressure pump for conveying liquefied gas, the effect of quickly and conveniently disassembling and assembling the high-pressure pump is effectively achieved.

[0008] As a further improvement of the present application, a handle is fixedly connected to the outer wall of the blocking cover.

[0009] As a further improvement of the present application, a slider is symmetrically fixedly connected to the inner wall of the baffle, a sliding groove corresponding to the slider is cut into the side wall of the connecting plate, and the sliding groove is slidably connected to the slider.

[0010] As a further improvement of the present application, a sealing gasket is fixedly connected to the inner wall of the baffle.

[0011] As another improvement of the present application, both the baffle plate and the connecting plate are coated with an anti-rust layer.

[0012] As another improved supplement of the present application, a magnetic sheet is fixedly connected to one end of the baffle plate close to the baffle cover, and the baffle cover and the magnetic sheet are attracted to each other.

[0013] To sum up, this solution can be realized. When installing the high-pressure pump body, the high-pressure pump body can be positioned and installed by inserting the bolts into the screw holes after the high-pressure pump body is positioned. Then, after the baffle cover is opened, the baffle plate is pulled out from the groove, covered on the connecting plate to wrap the connecting plate, and then the baffle cover is flipped down to seal the baffle plate. The baffle plate is used to seal the connecting plate between the wall or the surface of the object to achieve a sealing effect, so that when the high-pressure pump body is exposed to wind and rain for a long time, the bolts and screw holes will not rust, and the effect of quickly and conveniently disassembling and assembling the high-pressure pump is effectively achieved.

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method:

[0021] Figure 1-2 A high-pressure pump for liquefied gas transportation is shown, including a high-pressure pump body 1, a mounting base 2 is fixedly connected to the bottom end of the high-pressure pump body 1, connecting plates 3 are symmetrically fixedly connected to both ends of the mounting base 2, screw holes 5 are drilled on the connecting plate 3, bolts 4 are threadedly connected to the screw holes 5, a groove 6 is drilled on the mounting base 2 directly above the connecting plate 3, a baffle 7 is slidably connected to the groove 6, and the baffle 7 is engaged with the connecting plate 3, and the baffle 7 is rotatably connected to the end of the connecting plate 3 by a rotating shaft 10.

[0022] This solution can be achieved. When installing the high-pressure pump body 1, the high-pressure pump body 1 can be positioned and installed by inserting the bolts 4 into the screw holes 5. Then, after the baffle cover 9 is opened, the baffle plate 7 is pulled out from the groove 6, covered on the connecting plate 3 to wrap the connecting plate 3, and then the baffle cover 9 is flipped down to seal the baffle plate 7. The baffle plate 7 is used to seal the connecting plate 3 between the wall or the surface of the object to achieve a sealing effect, so that when the high-pressure pump body 1 is exposed to wind and rain for a long time, the bolts 4 and the screw holes 5 will not rust, and the effect of quickly and conveniently disassembling and assembling the high-pressure pump is effectively achieved.

[0023] The second implementation method:

[0024] Figure 2-3 It is shown that a handle 12 is fixedly connected to the outer wall of the baffle cover 9, a slider 11 is symmetrically fixedly connected to the inner wall of the baffle plate 7, a sliding groove 8 corresponding to the slider 11 is bored on the side wall of the connecting plate 3, and the sliding groove 8 is slidably connected to the slider 11, a sealing gasket is fixedly connected to the inner wall of the baffle plate 7, an anti-rust layer is coated on the baffle plate 7 and a magnetic sheet is fixedly connected to one end of the baffle plate 7 close to the baffle cover 9, and the baffle cover 9 and the magnetic sheet are attracted to each other.

[0025] This solution can be achieved. When the high-pressure pump body 1 is installed, the bolts 4 can be inserted into the screw holes 5 to fix it. Then, the cover 9 is opened upwards by the handle 12, and the baffle 7 is moved out of the groove 6, so that the slider 11 is engaged with the slide groove 8 and then moved. When the baffle 7 wraps and covers the connecting plate 3, the cover 9 is closed. At this time, the connecting plate 3 is sealed by the sealing gasket, so that the bolts 4 and the screw holes 5 will not be corroded and rusted, and the effect of easy disassembly and assembly can be achieved.

[0026] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
