Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pulsating valve fluid filling pumps, in particular to a hydraulic buffer cup for cooperating with a precision pulsating valve fluid filling device. Background Technique
[0002] A pulsating valve fluid filling pump is a precision device for filling liquid medicines. When the pulsating valve fluid filling pump is in use, the hydraulic medium inside it will be consumed and needs to be replenished manually. During the manual injection process, there is a risk of damaging the filling equipment environment. In addition, when the pulsating valve fluid filling pump is subjected to high-temperature cleaning and disinfection, the hydraulic medium inside it is likely to turn into steam and float away, resulting in increased losses. Therefore, in view of the above current situation, there is an urgent need to develop a hydraulic buffer cup for cooperating with a precision pulsating valve fluid filling device that is easy to use, does not require manual injection of supplementary hydraulic medium into the pump body, and is convenient for absorbing the steam of the hydraulic medium, reducing the loss of the hydraulic medium, so as to overcome the deficiencies in current practical applications and meet the current requirements. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a hydraulic buffer cup for cooperating with a precision pulsating valve fluid filling device, which is easy to use, does not require manual injection of supplementary hydraulic medium into the pump body, and is convenient for absorbing the steam of the hydraulic medium, reducing the loss of the hydraulic medium.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0005] A hydraulic buffer cup for cooperating with a precision pulsating valve fluid filling device, comprising a buffer cup end cover, a buffer cup valve core, a buffer cup cavity, a first sealing ring, a second sealing ring, a bracket and a pulsating valve fluid filling pump. The pulsating valve fluid filling pump is installed on the bracket, and the buffer cup cavity communicated with it is installed on the pulsating valve fluid filling pump. The bottom of the buffer cup cavity is fixed with a discharge port inserted into the pulsating valve fluid filling pump. The top of the buffer cup cavity is installed with a buffer cup end cover, and the buffer cup end cover is connected with the buffer cup cavity by a thread. The buffer cup valve core extending into the buffer cup cavity is installed on the buffer cup end cover, and the buffer cup valve core is connected with the buffer cup end cover by a thread. The first sealing ring is installed at the inner bottom end of the buffer cup cavity, and hydraulic media are stored in both the buffer cup cavity and the pulsating valve fluid filling pump.
[0006] Preferably: The first sealing ring is located directly below the buffer cup valve core.
[0007] Preferably: Both the first sealing ring and the second sealing ring are O-shaped sealing rings.
[0008] Preferably: The second sealing ring is installed at the bottom of the buffer cup cavity.
[0009] The beneficial effects of the present utility model are as follows: For the hydraulic buffer cup of the precision pulsating valve fluid dispensing device, when using the pulsating valve fluid dispensing pump for infusion filling, screw the buffer cup valve core down to the bottom, so that the bottom of the buffer cup valve core presses against the first sealing ring, thereby isolating the hydraulic medium in the pulsating valve fluid dispensing pump and the buffer cup cavity from each other. When performing high-temperature cleaning and sterilization after filling, rotate the buffer cup valve core upward, so that the buffer cup valve core is separated from the first sealing ring. The hydraulic medium in the buffer cup cavity flows into the pulsating valve fluid dispensing pump through the discharge port for replenishment. At the same time, the hydraulic medium evaporated due to high temperature in the pulsating valve fluid dispensing pump is absorbed by the buffer cup cavity, thereby reducing the loss of the hydraulic medium to maintain the content of the hydraulic medium in the pulsating valve fluid dispensing pump. In summary, the present utility model is convenient to use, does not require manual injection of supplementary hydraulic medium into the pump body, and is convenient for absorbing the steam of the hydraulic medium, reducing the loss of the hydraulic medium.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0017] The following gives specific embodiments.
[0018] See Figures 1 to 4, in the embodiment of the present utility model, a hydraulic buffer cup for a precision pulsatile valve fluid filling device includes a buffer cup end cover 1, a buffer cup valve core 2, a buffer cup cavity 3, a first sealing ring 4, a second sealing ring 5, a bracket 7, and a pulsatile valve fluid filling pump 8. The pulsatile valve fluid filling pump 8 is installed on the bracket 7, and the buffer cup cavity 3 communicated therewith is installed on the pulsatile valve fluid filling pump 8. A discharge port 301 inserted into the pulsatile valve fluid filling pump 8 is fixed at the bottom of the buffer cup cavity 3. The second sealing ring 5 is installed at the bottom of the buffer cup cavity 3. The sealing performance between the buffer cup cavity 3 and the pulsatile valve fluid filling pump 8 is improved through the second sealing ring 5 to prevent leakage. The buffer cup end cover 1 is installed at the top of the buffer cup cavity 3. The buffer cup end cover 1 is connected to the buffer cup cavity 3 by a thread. The buffer cup valve core 2 extending into the interior of the buffer cup cavity 3 is installed on the buffer cup end cover 1. The buffer cup valve core 2 is connected to the buffer cup end cover 1 by a thread. The first sealing ring 4 is installed at the inner bottom end of the buffer cup cavity 3. The first sealing ring 4 is located directly below the buffer cup valve core 2. Hydraulic media 6 are stored in both the buffer cup cavity 3 and the pulsatile valve fluid filling pump 8. Under normal conditions, the bottom of the buffer cup valve core 2 abuts against the first sealing ring 4, so that the hydraulic media 6 in the buffer cup cavity 3 cannot flow into the pulsatile valve fluid filling pump 8.
[0019] Both the first sealing ring 4 and the second sealing ring 5 are O-ring seals.
[0020] Working principle: For the hydraulic buffer cup of the precision pulsatile valve fluid filling device, when using the pulsatile valve fluid filling pump 8 for infusion filling, the buffer cup valve core 2 is screwed down to the bottom, so that the bottom of the buffer cup valve core 2 abuts against the first sealing ring 4, thereby separating the hydraulic media 6 in the pulsatile valve fluid filling pump 8 and the buffer cup cavity 3 from each other. When performing high-temperature cleaning and sterilization after filling, the buffer cup valve core 2 is rotated upward, so that the buffer cup valve core 2 is separated from the first sealing ring 4. The hydraulic media 6 in the buffer cup cavity 3 flow into the pulsatile valve fluid filling pump 8 through the discharge port 301 for replenishment. At the same time, the hydraulic media 6 evaporated due to high temperature in the pulsatile valve fluid filling pump 8 are absorbed by the buffer cup cavity 3, thereby reducing the loss of the hydraulic media 6 to maintain the content of the hydraulic media 6 in the pulsatile valve fluid filling pump 8.
[0021] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
