The other end port of input port A mouthfuls of connection of disconnected valve, on-off valve one passes through pipeline connection accumulator, the subject speed limit cutting
B mouthfuls of delivery outlet of valve are connected to one end port of one end port of pressure valve two and on-off valve two respectively by pipeline, pressure valve
Two other end port loads connection fuel tank by back pressure by pipeline connection fuel tank, the other end port of on-off valve two.
It further, further include pressure valve one, the pipeline between the on-off valve one and accumulator also passes through described
Pressure valve one be connected to fuel tank.
It further, further include pressure gauge, the pressure gauge is by piping connection defeated with the hydraulic power source
On the pipeline of outlet.
The beneficial effects of the utility model are: 1) the pipe rupture valve function test device of the utility model uses accumulator
The instantaneous big flow that accumulation of energy generates, can test pipe rupture valve oil circuit insantaneous break function due to flow is excessive；2) by
It is provided with the bypass line to fuel tank of on-off valve on pipe rupture valve output circuit, speed limit can be tested when opening on-off valve
The operating condition of stop valve delivery outlet instantaneous loss of pressure；3) side to fuel tank of pressure valve is provided on the export oil circuit of accumulator
Siphunculus road because of the excessive insantaneous break functional test of flow, can guarantee instantaneous flow control in certain model pipe rupture valve
Within enclosing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the pipe rupture valve function test device of the utility model；
Wherein, accumulator 1, on-off valve 1, pressure valve 1, hydraulic power source 4, pressure valve 25, on-off valve 26, back pressure load
7, pressure gauge 8, fuel tank 9 is tested pipe rupture valve 10.
Specific embodiment
The specific technical solution of the utility model is further described with reference to the accompanying drawings of the specification.
As shown in Fig. 1, a kind of pipe rupture valve function test device of the utility model, including accumulator 1, on-off valve
One 2, pressure valve 1, hydraulic power source 4, pressure valve 25, on-off valve 26, back pressure load 7, pressure gauge 8 and fuel tank 9, feature exists
Be connected to by pipeline with fuel tank 9 in the input port of, the hydraulic power source 4, the delivery outlet of hydraulic power source 4 pass through pipeline respectively with on-off
One end port of valve 1 input port A mouthfuls of pipe rupture valve 10 is connected to subject, and the other end port of on-off valve 1 passes through pipe
Road is connected to accumulator 1, and B mouthfuls of delivery outlet of the subject pipe rupture valve 10 pass through pipeline one end with pressure valve 25 respectively
Port is connected to one end port of on-off valve 26, and the other end port of pressure valve 25 passes through pipeline connection fuel tank 9, on-off valve two
6 other end port passes through 7 connection fuel tank 9 of back pressure load.The pressure gauge 8 by piping connection with the hydraulic power source
On the pipeline of 4 delivery outlet connection.
Pipeline between the on-off valve 1 and accumulator 1 also passes through the pressure valve 1 and is connected to fuel tank 9.Pressure
Valve 1 can control the instantaneous flow that accumulator 1 exports within limits.
The pipe rupture valve experimental rig of the utility model, can be used for the overcurrent protection of verification experimental verification pipe rupture valve and mistake
Pressure two kinds of major functions of protection.
A. overcurrent protection function is tested
A, B mouth for being tested pipe rupture valve 10 are respectively arranged on this experimental rig, on-off valve 26 is powered, starting
Hydraulic power source 4, then hydraulic oil returns to fuel tank 9 by subject pipe rupture valve 10, and by back pressure load 7, at this time 4 flow of hydraulic power source
For normal discharge, it is tested pipe rupture valve 10 and works normally.It is powered when by stop valve 1, then a large amount of liquid stored in accumulator 1
Pressure oil then moment can enter working connection, and by being tested pipe rupture valve 10, then system stream can be detected by being tested pipe rupture valve 10
It measures excessive, to trigger its main valve plug, oil circuit is cut off, B mouthfuls will not have oil liquid to reserve, if having flow that can then pass through peace
Flowmeter loaded on B mouthfuls is shown, can also be realized by the valve core position sensor of detection subject pipe rupture valve 10.
B. drill rod breaking o-volt protection functional test
Sea is in actual work if drill rod breaking, the B mouth meeting instantaneous loss of pressure of pipe rupture valve, at this point, speed limit is cut off
Valve main valve should close, and prevent cylinder piston rod stall from stretching out.The test of o-volt protection function is realized by following principle:
When carrying out drill rod breaking o-volt protection function test, on-off valve 1, on-off valve 26 are powered off, and pressure valve 25 is adjusted
Whole to start hydraulic power source 4 to service pressure value, subject pipe rupture valve 10 enters normal operating conditions, on-off valve 26 is led to
Electricity is then tested 10 input port instantaneous loss of pressure of pipe rupture valve, and spool, spool should be closed rapidly by being tested pipe rupture valve 10 at this time
Whether by be installed on B mouthful of flowmeter display situation can be detected, can also be cut by detection subject speed limit if closing in time
Valve core position sensor on disconnected valve 10 detects.
