Abstract
The invention discloses a multi-work station ball valve blasting testing machine which belongs to the field of testing device. The testing machine comprises a testing host and a control cabinet. The testing host is divided into two layers; a testing table is arranged on the upper layer and a machine base is arranged on the lower layers. The testing table is provided with 3 to 10 testing work stations which are arranged in parallel and which can simultaneously test the pressure and blasting performance of 1 to 10 ball valves. In the test, hydraulic oil uses a solenoid directional control valve to push each piston; the compression rod of each piston can rise simultaneously; a special sealing fixture is used for sealing and clamping two ends of the ball valve. A hydraulic test pump is used for pouring the testing medium into the tested ball valve and boosting the pressure of the tested ball valve so as to test the ball valve. The testing machine can simultaneously seal, clamp, pour the testing medium into and test a plurality of ball valves. In the whole test process, a computer is used for automatically controlling the test through a PLC controller. And the testing machine has the advantages of stable performance, high work efficiency, low labor intensity, simple structure, high security, and so on.

Technical field
The present invention relates to a kind of multi-station ball-valve bursting test machine.
Background technology
Ball valve will bear certain pressure at work, because of under pressure, working for a long time, its voltage endurance capability can directly have influence on the serviceable life of ball valve, simultaneously also can cause taking place blasting phenomena owing to the instantaneous pressure of ball valve is excessive, in case valve generation explosion not only can threaten to operating personnel's life security but also cause damage for the property of enterprise.In order to guarantee the safe handling of ball valve product, with regard to must in time testing, guarantee the ex factory pass rate of ball valve to the bursting property of ball valve, take preventive measures.
For a long time, the pilot project of ball valve is the pressure test of carrying out at sealing property and casing rigidity always, and can't formulate the withstand voltage limit of ball valve.At present China still not have special in the sample testing equipment of explosion of ball valve.
Summary of the invention
Technical matters to be solved by this invention is: at the deficiencies in the prior art, the multi-station ball-valve bursting test machine that provides a kind of pressure to ball valve, the withstand voltage limit and its whether to conform to quality requirements and test, it can realize a plurality of ball valves are carried out the test of pressure and bursting property simultaneously.
For achieving the above object, the technical solution adopted in the present invention is as follows:
A kind of multi-station ball-valve bursting test machine, it comprises: test main frame, switch board.Main frame is divided into two-layer up and down, and the upper strata is a testing table, and lower floor is a support, and main frame is the integral vertical type structure.Testing table is made up of sealing clamp, crossbeam, support plate, depression bar, and 3-10 test station that is parallel to each other vertically is installed on support plate, can select simultaneously 1-10 ball valve to be carried out pressure and bursting property test.Each test station is provided with two special-purpose ball valve test sealing clamps, and one is fixed on the crossbeam, and another is fixed on the depression bar, and can move up and down along its axis, and the shape of sealing clamp and ball valve water inlet and water delivering orifice adapt.Tested ball valve below over against the position, be fixed with clamping cylinder.During test, hydraulic oil promotes each piston by solenoid directional control valve, and the depression bar on each piston rises simultaneously thereupon or descends, and the sealing synchronously of special-purpose sealing clamp also clamps the ball valve two ends,, to tested ball valve perfusion test(ing) medium and supercharging ball valve is tested with test pump.The whole test platform is built in main frame inside, can prevent effectively that article cause damage because ball valve generation explosion reaches on every side to operating personnel in the explosion bulge test process.
Motor, oil pump, fuel tank, reversal valve, oil cylinder, oil pipe, test pump are installed in the support, and fuel tank is connected by oil pipe with oil pump, and oil pump connects with hydraulic system, and hydraulic system connects with clamping cylinder.Test pump connects with pressue device, and pressue device connects with the ball valve water inlet, and pressue device is made up of solenoid valve, sensor, joint.The ball valve water delivering orifice connects with pressure relief device, and pressure relief device is made up of solenoid valve, joint, water tank.Hydraulic system is arranged on can reduce the noise that experimental enviroment is produced in the mainframe.
Switch board is made up of computing machine, display, printer, PLC programming controller, keyboard, control knob, power light.The output terminal of pressure unit connects with computing machine by the PLC system, so that computing machine can be from the pressure parameter of pressure unit acquisition test.Test parameters such as test pressure, dwell time, test station, test station number and trystate show by display, are provided with by mouse or keyboard.Control knob is used for connecting or powered-down, and power light connects with control knob.
In the such scheme, the oil cylinder clamping force can be according to the bore and the corresponding adjusting of pressure rating of tested ball valve, and to reduce the suffered external force of ball valve body, entire test is finished by the PLC controller automatically by computing machine.Owing to adopted special-purpose sealing clamp, a plurality of test station, hydraulic clamp sealing, pressue device and pressure relief device, work such as many deck valves door clamps simultaneously, the row's of filling medium, test detection have been realized, shortened the test period, improve test efficiency, reduced labour intensity, improve the experiment work environment, and had good versatility.
The present invention compared with prior art has the following advantages:
1. function is many: both can carry out pressure test to ball valve, and can carry out explosion bulge test to it again;
2. high efficiency: adopt the multistation structure, can be simultaneously the ball valve of a plurality of different bore specifications be carried out pressure and explosion bulge test;
3. safe and reliable: testing table adopts built-in structure, has effectively guaranteed operating personnel's safety.
4. saving space: main frame and switch board all adopt the integral vertical type structure, make it floor area and reduce.
5. casing and sealing clamp adopt the stainless steel material manufacturing, corrosion-vulnerable not when contacting with water.
Concrete structure of the present invention is provided by following examples and accompanying drawing:
