Abstract
The utility model discloses an isolation membrane-type isolation bag. The isolation membrane-type isolation bag comprises an isolation bag body, wherein an isolation membrane is arranged in the isolation bag body; the isolation bag body is divided into two accommodating chambers by the isolation membrane; one accommodating chamber is a measured medium accommodating chamber; the other accommodating chamber is an isolation liquid accommodating chamber; a measured medium leading-in opening is formed in the measured medium accommodating chamber; an isolation liquid filling opening is formed in the isolation liquid accommodating chamber; the isolation liquid filling opening also serves as a measurement instrument access port. A measured medium accommodating chamber exhaust hole is also formed in the measured medium accommodating chamber; an isolation liquid accommodating chamber exhaust hole is also formed in the isolation liquid accommodating chamber; the isolation membrane is a spherical isolation membrane; a spherical isolation membrane protective mesh is arranged in a position, which is 5 mm to each of the two sides of the spherical isolation membrane; the two protective meshes are respectively welded on the inner walls of the two accommodating chambers. By adopting the isolation membrane-type isolation bag, the stability of a pressure-leading system can be greatly improved, and meanwhile, the problem that the pressure-leading system is frozen caused by the fact that the anti-freezing performance of the isolation liquid is reduced because the isolation liquid is diluted in winter is solved.
Description
Technical field
The utility model relates to differential pressure flowmeter and hydrodynamic pressure is measured accessory, specifically diaphragm type isolation bag.
Background technology
While using differential pressure flowmeter to measure fluid flow or measuring channel medium pressure, in impulse system, should fill with spacer pad, should filling antifreeze spacer pad in the north.But great majority (antifreeze) spacer pads be all water miscible, in use inevitably there is measured medium and spacer pad generation friendship molten, the consequence of bringing is: 1, spacer pad is diluted the original performance that has changed spacer pad; 2,, because spacer pad is diluted, produce additional measuring error; 3, spacer pad has polluted measured medium.This is the weak point of tradition isolation bag, is also the insurmountable problem of tradition isolation bag.
Summary of the invention
The purpose of this utility model is to provide diaphragm type isolation bag, can thoroughly solve in measuring process, (antifreeze) spacer pad and measured medium are handed over molten problem, can improve greatly impulse system stability, also solved the resistance to frost that has reduced spacer pad winter because spacer pad is diluted, caused the problem of the passive knot of impulse system simultaneously.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, diaphragm type isolation bag, comprises isolation bag body, and described isolation bag body interior is provided with a barrier film, isolation bag body is divided into two rooms, a room is measured medium room, and another room is spacer pad room, and described measured medium room offers measured medium intake, described spacer pad room offers spacer pad filling exit, and described spacer pad filling exit is simultaneously also as measurement instrument access port.
Described measured medium room also offers measured medium room vent port, and described spacer pad room also offers spacer pad room vent port.
Described barrier film is the barrier film of spherical.
5mm place, described spherical barrier film both sides is respectively equipped with spherical barrier film catch net, and two catch nets are welded in respectively on two room inwalls.
Described two rooms connect by the two room bindiny mechanisms that arrange each other, and two room bindiny mechanisms are bolt and the perforation fixture being used in combination.
Compared to prior art, the utlity model has following beneficial effect:
Diaphragm type isolation bag can perfectly be realized measured medium and spacer pad in measuring process and isolate completely, solve thoroughly measured medium and spacer pad and handed over molten problem, realize that spacer pad is not diluted and measured medium is not isolated the object that liquid pollutes, can improve greatly impulse system stability, solve the resistance to frost that has reduced spacer pad winter because spacer pad is diluted simultaneously, caused the problem of the passive knot of impulse system.Improve the accuracy of measuring and reduce the maintenance in using.
Brief description of the drawings
Fig. 1 is the structural drawing of diaphragm type isolation bag of the present utility model (liquid specific);
Fig. 2 is the structural drawing of diaphragm type isolation bag of the present utility model (gas specific).
In figure: 1, measured medium room 1; 2, spacer pad room; 3, barrier film; 4, barrier film catch net; 5, spacer pad room vent port; 6, measured medium room vent port; 7, measured medium intake; 8, spacer pad filling exit; 9, two room bindiny mechanisms.
Embodiment
Relevant detailed description of the present utility model and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing only provides the use of reference with explanation, is not used for the utility model to be limited.
As shown in Figure 1, liquid specific diaphragm type isolation bag, comprise isolation bag body, described isolation bag body interior is provided with a barrier film 3, and isolation bag body is divided into upper and lower two rooms, and upper chamber is measured medium room 1, lower chamber is spacer pad room 2, described measured medium room offers measured medium intake 7, and described spacer pad room 2 offers spacer pad filling exit 8, and described spacer pad filling exit is simultaneously also as measurement instrument access port.Described measured medium room also offers measured medium room vent port 6, and described spacer pad room also offers spacer pad room vent port 5.Two vent ports are all opened in the top of two containers.
Described barrier film is the barrier film 3 of spherical, the barrier film that this barrier film is upper drum type.5mm place, described spherical barrier film both sides is respectively equipped with spherical barrier film catch net 4, two catch nets and is welded in respectively on two room inwalls.Described two rooms connect by the two room bindiny mechanisms 9 that arrange each other, and two room bindiny mechanisms are bolt and the perforation fixture being used in combination.
As shown in Figure 2, gas specific diaphragm type isolation bag, comprise isolation bag body, described isolation bag body interior is provided with a barrier film 3, and isolation bag body is divided into upper and lower two rooms, and lower chamber is measured medium room 1, upper chamber is spacer pad room 2, described measured medium room offers measured medium intake 7, and described spacer pad room 2 offers spacer pad filling exit 8, and described spacer pad filling exit is simultaneously also as measurement instrument access port.Described measured medium room also offers measured medium room vent port 6, and described spacer pad room also offers spacer pad room vent port 5.Two vent ports are all opened in the top of two containers.
Described barrier film is the barrier film 3 of spherical, the barrier film that this barrier film is lower drum type.5mm place, described spherical barrier film both sides is respectively equipped with spherical barrier film catch net 4, two catch nets and is welded in respectively on two room inwalls.Described two rooms connect by the two room bindiny mechanisms 9 that arrange each other, and two room bindiny mechanisms are bolt and the perforation fixture being used in combination.
Diaphragm type isolation wraps in original tradition isolation bag and has set up a spherical barrier film device, and measured medium and spacer pad are separated completely, both can not be handed over molten, has solved that spacer pad is diluted and the problem of spacer pad pollution measured medium.The contour structures of this isolation bag and connected mode are similar to tradition isolation bag.When installation, positive and negative terminal isolation bag must strictly be arranged on same level height, and spacer pad can pour into from lower end transmitter interface.Tank momentum should ensure that isolation fully fills insulated chamber, makes in it, there is not gas as far as possible.
