Abstract
A test apparatus for measuring the flow pressure of a gas in a gas fitting or a line comprises connecting apparatus 3 which connects to a measuring connector 1. Closure plug or valve 2 may be opened by inserting an associated tool 4, such as a screwdriver. The test apparatus has a Y-shaped configuration having a measuring channel 6 branching off from main channel 5 to a pressure gauge. The main channel 5 may be closed during measurement by a closure cap 8.
Description
TEST APPARATUS
The innovation relates to a test apparatus, in particular for measuring the flow pressure of a gas in a gas fitting or a line according to the preamble of protective claim 1.
Test apparatuses for measuring the flow pressure in a gas fitting or line are used by installers for maintenance purposes. Hitherto, during the maintenance of the Fine or fitting to be investigated, a sealing plug or a valve on a measuring connector is opened by means of a suitable tool and a connecting hose is connected thereto. Thrs hose is then connected to a pressure gauge and the flow pressure could thus be determined by means of this test apparatus. However.
when fixing the connecting hose to the valve, a certain amount of gas escapes briefly. It can also be difficult to carry out scrupulous maintenance since the housings of the gas fittings or lines to be investigated are mounted in an increasingly compact and space-saving manner in or on gas-operated devices, for example, gas heaters. As a result, the attachment of the connecting hose to the valve is possibly difficult for a filler; at least when work is to be carried out on a device for the first time The innovation is based on the object of optimising the measurement of the flow pressure in a gas filling or line and providing a practice-oriented aid for this purposa The main features of the innovation are given in claim 1. Further embodiments can be deduced from the dependent claims.
The test apparatus for measuring the flow pressure is characterised in that the test apparatus can be brought to the measuring connector and the pressure gauge can be connected to the measuring connector via a special connecting apparatus, where the closure plug or the valve can be actuated by introducing an associated tool. A gastight flow pressure measurement is hereby possible.
The test apparatus provided according to the innovation has a hollow shape having a main channel and having an end region serving as an adapter to the measuring connector. The closure plug or the valve is actuated by an associated tool which can be inserted in the adapter. The gas to be investigated thereby flows from the valve and the flow pressure can be determined by means of a pressure gauge. The V-shaped configuration having a measuring channel branching off from the main channel enables the pressure gauge to be connected to the test apparatus. The measuring channel has a corrugated end in order to connect the pressure gauge tightly to the test apparatus.
Furthermore, the test apparatus provided according to the innovation enables a gastight connection to the measuring connector by means of a special connecting apparatus. The connecting apparatus has a plug-in nipple end for a fixed and gastight fit by embracing the measuring connector as an adapter in the end region. Consequently, gas can only escape via the channels of the test apparatus on opening the valve.
Due to a rigid shape, an associated tool can be inserted as far as the measuring connector without tilting, so that the closure plug or the valve can be actuated and the gas to be studied flows through the channels of the test apparatus.
Furthermore, a closure cap is fixed undetachably in the end region of the test apparatus. With this cap the main channel can be sealed after the tool has been removed from the test apparatus. The test apparatus is thereby sealed in a gastight manner on all sides and a constant flow pressure can then be measured by connecting the pressure gauge.
Alternatively or additionally to this, an important embodiment of the innovation further provides that the test apparatus is sealed in a gastight manner by a seal in the area of the tool insertion opening. Following a flexible penetration by a tool, a gastight enclosure of the tool and a gastight sealing after removal is thereby possible. Consequently, a constant flow pressure can also be measured in this embodiment as a result of the gas-tightness.
The test apparatus avoids any undesired escape of gas into the surroundings since no gas can be exchanged with the surroundings due to the sealing of the tool insertion opening and the fixing of the plug-in nipple end on the valve. A connection of the pressure gauge to the test apparatus and an easier, rapid measurement of the flow pressure in the gas fitting or line is possible with the aid of the measuring channel. A conventional screwdriver is preferably used as the tool or aid. For the measurement the test apparatus is therefore provided with a pressure gauge and attached to the measuring connector. The tool for actuating the closure plug or the valve is then passed through. -3.-
Further features, details and advantages of the innovation are obtained from the wording of the claims and from the following description of an exemplary embodiment by means of the drawings. Figures 1 and 2 show schematically, each in longitudinal section, the structure of a test apparatus.
Fig. 1: with tool introduced into the main channel and Fig. 2: with closed closure cap.
The test apparatus for measurement of the flow pressure in a gas fitting or line not shown is associated with a measuring connector 1, which has a closure plug 2.
A pressure gauge not shown can be connected by means of the test apparatus via a special connecting apparatus 3 to the measuring connector 1. The closure plug 2 is to be opened by inserting an associated tool 4 so that gas flows out.
The test apparatus has a Y-shaped configuration having a measuring channel 6 branching off from the main channel 5 to the pressure gauga A gas-tight connection to the measuring connector 1 can be made by a connecting apparatus 3, where the connecting apparatus has a plug-in nipple end 7 for a fixed and gastight fit by embracing the measuring connector 1 as an adapter in the end region.
The main channel 5 of the test apparatus is closed during the measurement by a closure cap 8 which is fixed undetachably to the test apparatus in the end region.
Furthermore, the free end of the measuring channel 6 is configured as a hose nozzle on its outer side in order to connect a pressure gauge directly or via a hose or a pipeline.
