Abstract
Disclosed in the invention is a cylinder pressure measurement device comprising a connecting pipe (1). An indicator valve (2) and a sensor adapter (3) are connected to one end of the connecting pipe (1). And a pressure sensor (4) is connected to the sensor adapter (3). The device has the following beneficial effects: when an air cylinder pressure needs to be measured, the connecting pipe of the device is communicated with the air cylinder through a small hole formed in a cylinder cover directly. The device with a simple structure can be used conveniently; the damage on the sensor is reduced; the pressure wave interference is reduced; the cylinder pressure measurement precision is improved; and the damage on the pressure sensor is also reduced.
Description
Technical field
The present invention relates to high power gas machine technology field, specifically, is a kind of cylinder pressure determinator.
Background technology
For high power gas machine, the cylinder pressure that can measure gas engine is accurately particularly important, the cylinder pressure measured is too high or too low all can cause larger impact to the operation of gas engine, cylinder pressure detects too low, gas engine constant temperature is easily caused to raise the danger such as even blast, cylinder pressure detects higher, and gas engine may cause cisco unity malfunction again.
For existing gas engine cylinder pressure checkout equipment, often through the aperture that cylinder head is communicated with cylinder, pressure transducer is set directly on cylinder, but usually due to frequent dismounting, easily pressure transducer is damaged, and due to joint short and small, dismounting bother.
Summary of the invention
In order to solve the problem, the present invention proposes a kind of cylinder pressure determinator, is arranged on by pressure transducer on connecting pipe, when measuring cylinder cylinder pressure, this equipment is arranged in cylinder head, and is communicated with cylinder, carry out cylinder pressure and measure, dismounting is simple, easy to use, reduces the interference of pressure wave.
A kind of cylinder pressure determinator, comprises connecting pipe, is connected with indicator valve and sensor adapter in one end of described connecting pipe, described sensor adapter is connected with pressure transducer.
By above-mentioned design, when measuring cylinder cylinder pressure, by the connecting pipe of this equipment directly by the aperture in cylinder head, be communicated with cylinder, dismounting is simple, not easily causes the destruction to pressure transducer and cylinder head.
Further, described connecting pipe internal diameter is 5 millimeters to 7 millimeters.
Further describe again, conveniently the dismounting of sensor, described connecting pipe pipe range 220 millimeters.
Further describe again, be conveniently connected with indicator valve, and ensure impermeability, in the other end termination of described connecting pipe, be provided with two adjacent internal threads and and this termination is outer-hexagonal head.
Further describe, the material of described connecting pipe is stainless steel material again.
Beneficial effect of the present invention: when cylinder cylinder pressure will be measured, by the connecting pipe of this equipment directly by the aperture in cylinder head, be communicated with cylinder, device structure is simple, easy to use, reduces the destruction to sensor, reduce the interference of pressure wave, improve cylinder pressure estimating precision.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is sectional view of the present invention;
1. connecting pipes, 2. indicator valve in figure, 3. cylinder pressure sensor adapter, 4. cylinder pressure sensor.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention and principle of work are described in further detail.
Embodiment:
As can be seen from Fig. 1 and Fig. 2: a kind of cylinder pressure determinator, comprises connecting pipe 1, be connected with indicator valve 2 and sensor adapter 3, sensor adapter 3 is connected with pressure transducer 4 in one end of connecting pipe 1;
Preferably, in the present embodiment, connecting pipe 1 internal diameter is 5 millimeters;
Preferably, connecting pipe 1 pipe range 220 millimeters;
Preferably, in the other end termination of connecting pipe 1, two adjacent internal threads are provided with and and this termination is outer-hexagonal head.The material of connecting pipe 1 is ferrous materials.
Principle of work of the present invention, when cylinder cylinder pressure will be measured, by the connecting pipe of this equipment directly by the aperture in cylinder head, be communicated with cylinder, now pressure transducer is communicated with cylinder, when cylinder quits work, when stopping pressure measurement, connector is separated with cylinder, dismounting is simple, easy to use, efficiently reduce the interference of pressure wave, improve accuracy of detection.
