[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-pressure container used for analyzing spray conditions under high pressure.

0002

[Prior Art] In order to analyze the state of fuel spray in the cylinder of a diesel engine, an injection nozzle is inserted into a high-pressure container that has a viewing window with a glass hermetically fixed at a certain angle to the side of the container. Data is recorded visually or with a measuring device after injection.

0003

[Problems to be Solved by the Invention] Recently, optical measuring instruments using laser light have been developed to analyze spray, making it possible to measure spray conditions from multiple directions and angles. However, because the conventional high-pressure container has a viewing window at a fixed angle, it is not possible to measure the spray situation from multiple angles with one high-pressure container, and it is necessary to replace it with multiple high-pressure containers with viewing windows at different angles. must be measured. This requires time to change setups and increases costs.

[0004] An object of the present invention is to provide a high-pressure container for spray analysis that eliminates such conventional problems.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention has an opening on both sides having a mounting surface parallel to the central axis of the pressure-resistant container. A container body having an auxiliary window with glass fixed at a position within a range of 90 degrees from the opening position and an injection nozzle insertion port, and mounting of the opening part offset at a required angle with respect to the central axis of the container. It is composed of an adapter that can be attached to and detached from a seat surface, and a window frame member to which a window glass is fixed and that can be attached and detached to both the adapter and the mounting seat surface of the opening of the container body.

[0006]

[Operation] With the above configuration, by attaching the adapter to the container body and attaching the window frame member to this adapter, measurement can be obtained from the required angle, and by attaching the window frame member directly to the container body, the center of the container can be measured. Measurements can be taken from angles parallel to the axis. Furthermore, from the auxiliary window, 9
It is also possible to measure from the 0° direction, making it possible to measure the spray situation from multiple angles with one container body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings. In FIGS. 1 to 4, reference numeral 1 indicates a container body made of a pressure-resistant material. This container body 1 has an opening 3 having mounting seats 2 parallel to the central axis 0 of the container body on both sides, and a glass is airtightly fixed at a position within a plane within a range of 90 degrees from the opening 3. An auxiliary window 6 and an injection nozzle insertion port 4 into which the injection nozzle 5 is inserted so that the injection port is located on the central axis 0 of the container body 1 are provided.

Reference numeral 7 denotes an adapter that can be attached to and detached from the mounting seat surface 2 of the opening 3 of the container body 1 with a bolt 8;
a first mounting seat surface 7a parallel to the central axis 0 of the container body 1;
and a second mounting seat surface 7b inclined at a predetermined angle with respect to the central axis 0.

Reference numeral 9 denotes a window frame member, on which a glass 10 is airtightly fixed by a glass holder 11. This window frame member 9 can be attached to and removed from both the second mounting seat surface 7b of the adapter 7 and the mounting seat surface 2 of the container body 1 with bolts 12.

Since the present invention has the above-mentioned structure, the adapter 7 is attached to the first mounting seat surface 7a on the mounting seat surface 2 formed in the openings 3 on both sides of the container body 1, as shown in FIG. Further, the window frame member 9 is attached to the second mounting seat surface 7b, and the injection nozzle 5 is inserted through the injection nozzle insertion port 4 so that the injection nozzle is located on the central axis 0 of the container body 1, and the spray is applied. Measure the situation with an optical measuring instrument.

In this case, when the mounting angles θ1 and θ2 of the window frame member 9 by the adapter 7 are each set to 15°, the sum of both angles becomes 30°, and this inclination angle is determined by an optical measuring device using a laser beam. This is the optimal angle for measuring the size and velocity of spray particles.

Further, when analyzing the spray by the transmission attenuation method, shadow photography, or Malvern, it is desirable that the window frame member 9 be parallel to the central axis 0 of the container body 1. In this case, as shown in FIG. 4, the adapter 7 is connected to the container body 1.
By removing the window frame member 9 and directly attaching it to the mounting seat surface 2 of the container body 1, measurements can be made immediately at an ideal angle.

Furthermore, when measuring with laser sheet light, it is possible to perform the measurement by irradiating the laser sheet light through the auxiliary window 6 located 90° in plane from the opening 3 of the container body 1. be.

[0014]

As described above, according to the method of the present invention, openings having mounting surfaces parallel to the center axis of the container are provided on both sides, and a glass plate is provided at a position within a plane within a range of 90 degrees from the opening position. a container body having a fixed auxiliary window and an injection nozzle insertion port; an adapter offset at a required angle with respect to the central axis of the container and detachable from the mounting surface of the opening; and a window glass. This is a high-pressure container for spray analysis, which is composed of a window frame member which is fixedly attached to the adapter and which is removable from both the adapter and the mounting seat of the opening of the container body.
Attach the window frame member to one container body via an adapter,
Alternatively, by directly attaching it, it can be changed into a container that is optimal for various measurement methods, and has the advantage that setup changes can be performed in a short time when changing measurement methods, and the cost of the high-pressure container can be reduced.
