Description

Plunger valve body

Technical Field

The utility model relates to the technical field of fluid delivery, in particular to a plunger valve body.

Background

In the field of precision liquid delivery, special infusion sets are required to achieve accurate feeding of fluids. For example, the unit application discloses a liquid delivery apparatus of patent number 202021517573.9 in which accurate feeding of fluid is achieved by controlling the operation of a plunger valve. The plug valve has a valve body structure with a sealing component for sealing a valve cavity, and a piston is movably connected in the valve cavity.

The volume of the cavity for liquid to enter in the existing valve body is fixed, and only 100ml of liquid can be contained at present, so that the size of the cavity can not be adjusted according to requirements.

Disclosure of Invention

Valve body 1, cavity 10, piston 2, seal assembly 3, hold liquid pipe 4, cock body 5, step 11.

Detailed Description

Embodiments of the present utility model are further described with reference to fig. 1-2.

The specific structure of the embodiment is as follows: the valve comprises a valve body 1 with a cavity 10, a piston 2 and a sealing component 3, wherein the piston 2 is movably connected with the cavity 10 of the valve body 1, the sealing component 3 is arranged at the lower part of the valve body 1, a liquid storage pipe 4 is detachably connected in the cavity 10, the liquid storage pipe 4 is hollow, and the liquid storage pipe 4 is made of high polymer polypropylene materials.

The piston 2 moves in the liquid storage pipe 4, the end part of the piston 2 is detachably connected with a plug body 5, the plug body 5 is made of medical rubber, a connecting hole is formed in the plug body 5, and the end part of the piston 2 extends into the connecting hole and is in threaded connection with the connecting hole. The piston 2 is made of ceramic material, the inner wall of a connecting hole on the plug body 5 is provided with internal threads, the outer peripheral wall of the end of the piston 2 is provided with external threads, and then the piston 2 and the plug body 5 are fixedly connected through threads. The diameter of the plug body 5 is adapted to the caliber of the reservoir tube 4.

After the liquid storage pipes 4 with different specifications are replaced, the piston 2 moving in the liquid storage pipes is not replaced, and the plug body 5 on the piston 2 is replaced. The different sizes of the liquid storage tubes 4 are different in thickness.

The chamber 10 is provided with a stepped portion 11 for abutting the end of the reservoir tube 4, and the end of the reservoir tube 4 abuts against the stepped portion 11 after the reservoir tube 4 is inserted into the chamber 10.

The above description is only a preferred embodiment of the present utility model, and is not intended to limit the utility model, but one skilled in the art can make common changes and substitutions within the scope of the technical solution of the present utility model.
