Abstract
The utility model discloses a liquid isolator which is suitable to checking various pressure gauges. An elasticity barrier film is arranged in an isolated chamber in order to divide the film into two cavities, one cavity is filled with isolated liquid while the other cavity is filled with working liquid, so the mixing of difference liquid can be efficiently prevented.
Description
The utility model relates to a kind of liquid spacer assembly, particularly a kind ofly is used to check various manometric fluid isolators.
In the various tensimeter processes of maintenance, in order to prevent that various oil from entering in the tensimeter, the general hydrometer method that adopts is isolated hydraulic fluid and oil, promptly earlier hydraulic fluid is injected in the chamber of fluid isolators, and then oil is injected in the chamber of this fluid isolators, proportion difference according to them is separated them, does like this and liquid and oil can not be separated fully, two kinds of close liquid of proportion is isolated then have incomplete factor especially.
The purpose of this utility model provides a kind of fluid isolators that various liquid are isolated that is suitable for.
The purpose of this utility model is achieved in that the liquid separate cavities that has two passages, and an end communicates with tensimeter, and the other end communicates with petroleum pipeline.One elastomeric isolation film is installed in this separate cavities, this chamber is divided into two chambeies, fluid partitioning is injected in one of them chamber, and hydraulic fluid is injected in another chamber.
The utility model only needs at the inner chamber of fluid isolators one elastomeric isolation film to be installed, and can prevent the mixing of two kinds of different liquids effectively.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a sectional view of the present utility model.
The utility model is made up of cavity 1, cavity 2, and cavity 1 communicates with tensimeter, and cavity 2 communicates with petroleum pipeline, and crimping one has the oil resistant rubber film 4 of O-ring seal 3 in separate cavities.Cavity 1 fills with water during use, cavity 2 is filled with oil, make pressure after, pasta moves upward, and promotes the oil resistant rubber film and raises up, cavity 1 pressure increases, and can measure manometric pressure.
Claims (3)
1, a kind of fluid isolators comprises the liquid separate cavities that has two passages, it is characterized in that installing in this liquid separate cavities an elastomeric isolation film.
2, fluid isolators according to claim 1 is characterized in that the elastomeric isolation film is installed between two passages.
3, fluid isolators according to claim 1 is characterized in that the elastomeric isolation membrane material made by oil resistant rubber.
