Abstract

The present utility model discloses a pressure measuring device. The device is characterized in that the device comprises an isolation pot, the isolation pot is connected with a stop valve through a pressure-leading port, and the isolation pot is also connected with an inlet valve. The device is simple in structure and wide in application scope.

Description

A kind of device for pressure measurement
Technical field
The utility model relates to a kind of device for pressure measurement, belongs to the pressure survey field.
Background technology
When convection cell carries out pressure survey under operating modes such as solidifying, contain solid particle, high temperature is arranged easily, usually can adopt the barrier film mode to measure.But adopt barrier film can reduce precision, and the barrier film heatproof is limited, can not be competent at all similar operating modes fully, barrier film is in a single day blocked, the cleaning difficulty.
Summary of the invention
The purpose of this utility model is to solve the barrier film mode to measure the problem that the barrier film heatproof of appearance is limited, be difficult to clear up after stopping up, and a kind of simple in structure, device for pressure measurement that the scope of application is extensive is provided.
In order to achieve the above object, the utility model provides a kind of device for pressure measurement, it is characterized in that, comprises sealing chamber, and sealing chamber is connected with stop valve by the impulse mouth, and sealing chamber also is connected with imported valve.
Preferably, described sealing chamber also is connected with outlet valve with tensimeter respectively.
Preferably, described imported valve is connected with throttling valve, is connected with tensimeter between imported valve and the sealing chamber.
The utility model carries out isolation measurement by the mode that adopts topping up or inflation, according to different operating modes, can select to be incubated (heating) or not to be incubated.The utility model is simple in structure, easy to operate, maintenance convenience, good economy performance, to compare barrier film differential pressure meter precision high, and parts can conveniently obtain, and be not subjected to temperature, dielectric viscosity, factor affecting such as solid particle, thereby the scope of application is extensive.
Description of drawings
Fig. 1 is the structural representation of a kind of device for pressure measurement of employing topping up isolation;
Fig. 2 is for adopting the structural representation of a kind of device for pressure measurement of inflating isolation.
Description of reference numerals
1 is sealing chamber, and 2 is imported valve, and 3 is tensimeter, and 4 is the impulse mouth, and 5 is stop valve, and 6 is outlet valve, and 7 is measured device, and 8 is throttling valve.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
Embodiment 1
The utility model is a kind of device for pressure measurement, as shown in Figure 1, is the structural representation of a kind of device for pressure measurement of adopting the topping up isolation.Sealing chamber 1 is connected with stop valve 5 by impulse mouth 4, and sealing chamber 1 also is connected with imported valve 2.Sealing chamber 1 also is connected with outlet valve with tensimeter 3 respectively and is connected.Stop valve 5 is installed perpendicular to measured device.
When in use, the pressure port of impulse mouth 4 and measured device 7 is remained on same level, by imported valve 2 to sealing chamber 1 interior injection spacer pad, until till impulse mouth 4 has micro-spacer pad to flow out, close imported valve 2.
When if fluid to be measured is full of sealing chamber 1 top, tensimeter 3 is positioned at the below of impulse mouth 4, like this, by the pressure that the height that tensimeter 3 readings is deducted spacer pad between tensimeter 3 table mouths and the impulse mouth 4 produces, namely is the pressure of the pressure port of measured device 7.In setting pressure table 3, should show mouth on a surface level, with Reduce measurement error with tensimeter 3 as far as possible.
If fluid to be measured is heavier than spacer pad, then need tensimeter 3 upper, need accordingly first measured medium to be filled with sealing chamber 1, corresponding, pressure need to add the reading of tensimeter 3 pressure gauge 3 and show the pressure that the height of spacer pad between mouth and the impulse mouth 4 produces.
After measuring end, can open outlet valve 6, liquid is discharged sealing chamber 1.
Embodiment 2
The utility model is a kind of device for pressure measurement, as shown in Figure 2, and for adopting the structural representation of a kind of device for pressure measurement of inflating isolation.Sealing chamber 1 is connected with stop valve 5 by impulse mouth 4, and sealing chamber 1 also is connected with imported valve 2.Imported valve 2 is connected with throttling valve 8, is connected with tensimeter 3 between imported valve 2 and the sealing chamber 1.Stop valve 5 is installed perpendicular to measured device.
Before beginning to measure, first stop valve 5 cuts out, in sealing chamber 1, slowly be filled with separation gas by imported valve 2, when treating force value that tensimeter 3 indicated values measure a little more than needs, close imported valve 2; Slowly open stop valve 5, have small part of gas can enter measured device 7, then balance this moment.Measured medium does not contact with tensimeter 3, so can realize measuring media is not directly carried out pressure survey.When mounted, the root of sealing chamber 1 and testing pressure interface are at a surface level, to reduce the measuring error of bringing owing to liquid level.
Inflation isolation method in the present embodiment, the diameter of sealing chamber 1 is large, and is highly low, to reduce liquid level to the impact of measuring accuracy.
