Description
Technical field：
It the utility model is related to a kind of adjustable constant-pressure load testing device.
Background technology：
When air blower is tested in laboratory, flow and outlet pressure, fictitious load feelings are controlled mainly by tune outlet valve
Condition.But valve is becomes resistant load, when needing to test automatic running situation of the air blower under constant pressure loading condition, often
The scene of constant pressure load is needed with bulky gas buffer tank or finds, testing cost is higher.
Utility model content：
The utility model is to provide a kind of adjustable constant-pressure load to solve the above-mentioned problems of the prior art
Test device.
There is technical scheme used by the utility model：A kind of adjustable constant-pressure load testing device, including clamp nut,
Gland, blast pipe, guide rod, constant pressure floating block and constant voltage room, several described blast pipes are fixedly connected in constant voltage room, and blast pipe
Inner chamber and the inner chamber of constant voltage room connect, guide rod is located in blast pipe along blast pipe axis direction, and the bottom of guide rod with
The inner chamber bottom surface of constant voltage room is fixedly connected, and constant pressure floating block is connected on guide rod, and constant pressure floating block is placed in blast pipe, and gland, which is worn, to be connect
In on guide rod, clamp nut is threaded on guide rod, and gland is connected to the upper port of blast pipe, and gland is by blast pipe
Upper port is sealed, and exhaust outlet is provided with the side wall of blast pipe.
Further, axial direction of the exhaust outlet along blast pipe is set.
Further, the lower surface of the constant voltage room is provided with flange screw and adapter mouth.
The utility model has the advantages that：The utility model is simple in construction, and cost is low, is easy to process, shared body
Product is small, in light weight, and convenient installation and regulation, pressure is constant, can adjust as needed.
Brief description of the drawings：
Fig. 1 is the utility model structure chart.
Embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model discloses a kind of adjustable constant-pressure load testing device, including clamp nut 1, gland
2nd, blast pipe 3, guide rod 4, constant pressure floating block 5 and constant voltage room 6, several blast pipes 3 are fixedly connected in constant voltage room 6, and blast pipe 3
Inner chamber and the inner chamber of constant voltage room 6 connect, guide rod 4 is located in blast pipe 3 along the axis direction of blast pipe 3, and the bottom of guide rod 4
End is fixedly connected with the inner chamber bottom surface of constant voltage room 6.Constant pressure floating block 5 is connected on guide rod 4, and constant pressure floating block 5 is placed in blast pipe 3
Interior, gland 2 is connected on guide rod 4, and clamp nut 1 is threaded on guide rod 4, and gland 2 is connected to the upper end of blast pipe 3
Mouthful, gland 2 seals the upper port of blast pipe 3.
Exhaust outlet 31 is provided with the side wall of blast pipe 3.Axial direction of the exhaust outlet 31 along blast pipe 3 is set.
Flange screw 7 and adapter mouth 8 are provided with the lower surface of constant voltage room 6.
When in use, blower exit conduits are directly connected to the adapter mouth 8 of the test device by flange screw 7, when
When pressure reaches setting pressure in the constant voltage room 6 of test device, constant pressure floating block 5 can float automatically along guide rod 4, and unnecessary gas leads to
Exhaust outlet 31 is crossed to discharge.Constant pressure floating block 5 can automatically adjust the amount of discharge gas according to the size of air blower flow, keep constant voltage room
Pressure is constant in 6.When needing to test the constant pressure load of different pressures, can be realized by adjusting the quantity of constant pressure floating block, side
Just it is quick.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
The scope of protection of the utility model.
