Description

The valve pressure torsion-testing machine of holding concurrently

Technical field

The utility model belongs to the technical field of valve examination test equipment, and concrete ground says that the utility model relates to a kind of valve pressure and torque-combining proving installation.

Background technology

Industrial valve; Like stop valve, ball valve, gate valve, butterfly valve etc.; All be the engineering goods of pressing in bearing, must under specified pressure, rated flow, open, close, hoisting capacity with open and close moment be valve opening or close the acting force or the moment that must apply.Valve opening and closing moment is to embody an important indicator of valve level of aggregation, and all valve inspection devices are mainly measured the intensity and the sealing property of valve according to national standard at present, and so inspection can not reflect the operation and the usability of valve.The open and close torque of valve is related to design, manufacturing and the use of valve, lacks actual valve torque data, causes the supporting aspect of drive unit type selecting often to go wrong, and is not that moment of torsion is selected surplus, causes waste, is exactly that the moment of torsion selection is not enough, can't use.At present, the main manually-operated mode of dial torque wrench that adopts of valve torque test, bigbore valve needs many people to detect; This kind detection mode labour intensity is big; Firmly size and speed are inhomogeneous, as carry out thousands of cyclic tests, and test number (TN) is difficult to guarantee.The API6D of american petroleum institute standard has clear and definite prescribed torque metering system to the valve opening and closing torque measurement, and existing machines can not satisfy and applies relevant pressure and carry out the requirement that moment of torsion detects.

The utility model content

For solving the problems of the technologies described above, the utility model problem to be solved provides a kind of valve pressure torsion-testing machine of holding concurrently, and its objective is in the test valve pressure provides open and close torque, realizes that pressure torque measures simultaneously, improves detection efficiency.The technical scheme that the utility model adopted is: a kind of valve pressure torsion-testing machine of holding concurrently, mainly comprise base, roof pressure motor, movable machine frame, roof pressure oil cylinder, and described roof pressure oil cylinder connects through the movable machine frame of installing on the roof pressure pull bar; The sealing pad of installing on the described movable machine frame is communicated with low-pressure pump and hydraulic pressure high-pressure hydraulic pump; It is characterized in that: have that a torsion-testing stand is vertical to be installed on the base; Digital torque gauge in the described torsion-testing stand is connected with rotating type torque measuring sensor, and described rotating type torque measuring sensor is connected to and tests recruitment and pretends on the logical oil motor.

Described torsion-testing stand can move left and right.

Said rotating type torque measuring sensor can move up and down.

The described valve pressure torsion-testing machine of holding concurrently is furnished with signal output system.

Advantage and the good effect that the utlity model has are: because the utility model is improved on the architecture basics of existing roof pressing type valve test machine, so be easy to realize.Because of it adopts automatic control and dynamic torque test macro, make accuracy of detection high through sensor, the moment of torsion of valve can detect in the pressure test process, has improved detection efficiency; Carry out dynamic monitoring through pressure unit in the valve pressure test, improved accuracy of detection.The life of valve test adopts counter to carry out the number of times statistics, and the accuracy of warranty test can directly be carried out pressure test after the off-test, need not lift valve and raise the efficiency.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the front view of the utility model;

Fig. 2 is the side view of the utility model.

Embodiment

Specify the concrete structure of the utility model according to Fig. 1~2.A kind of valve pressure torsion-testing machine of holding concurrently mainly comprises base 1, roof pressure motor 6, movable machine frame 3, roof pressure oil cylinder 2, and described roof pressure oil cylinder 2 connects through the movable machine frame of installing on the roof pressure pull bar 43; The sealing pad of installing on the described movable machine frame 35 is communicated with low-pressure pump and hydraulic pressure high-pressure hydraulic pump; It is characterized in that: a torsion-testing stand 7 vertical being installed on the base 1 are arranged; Digital torque gauges 8 in the described torsion-testing stand 7 are connected with rotating type torque measuring sensor 9, and described rotating type torque measuring sensor 9 is connected to and tests recruitment and pretends on the logical oil motor 10.Described torsion-testing stand 7 can move left and right.Said rotating type torque measuring sensor 9 can move up and down.The described valve pressure torsion-testing machine of holding concurrently is furnished with signal output system 11.

Specified operational procedure is that this valve pressure torsion-testing machine is moved along roof pressure pull bar 4 by roof pressure oil cylinder 2 promotion movable machine frames 3, and valve is clamped on two sealing pads 5 on roof pressure motor 6 and the movable machine frame 3; The moment of torsion stand 7 that moves is to the valve center, and the torsion-testing frock that will be connected with torque tester 9, torque sensor 8, counter and oil motor 10 through the top oil cylinder moves down, and is connected on the valve rod.Open water intaking valve, start the hydraulic pressure high-pressure hydraulic pump, carry out the valve housing strength test; Open oil motor 10, valve-off carries out moment of torsion and valve seal test.Pressure unit becomes the standard industry signal with the moment of torsion transmitter with conversion of signals; Discern through PLC control system, module controls system; Gather the data of valve torque and pressure detection, be sent to the curve that signal output system 11 is drawn pressure test and torsion-testing.Set the valve switch number of times, oil motor drives frock and realizes 90 ° of intermittently uniform main storys, and valve open stops 5 seconds, and 90 ° of valve closings reverse.Directly test figure, pressure curve and torque curve are printed, also can deposit data in USB flash disk and preserve through interface through printer.
