Abstract
The utility model relates to a gas path structure capable of adjusting multiple stages of loads. A multiple-channel joint is provided at an outlet end of a pneumatic triplet, and the outlets of the shunt paths are respectively parallelly connected with at least two branch paths which are respectively composed of a pressure relief valve and an electromagnetic valve that are connected in series. After each branch path is gathered, the gathered branch paths are connected with an inlet of a three-position five-way electromagnetic valve. A gas outlet of the three-position five-way electromagnetic valve is respectively connected with a rodless chamber and a rod chamber of a cylinder through a throttle valve. According to the utility model, the cylinder is adopted for realizing reciprocation. The speed and active force are controlled through a pneumatic component. Multiple-branch parallel combination is adopted for controlling the gas pressure. The use of single expensive pneumatic component is prevented. The structure is reasonable and reliable. The multiple stages of loads can be adjusted accurately and effectively.
Description
Technical field
The utility model relates to the detection technique field, especially a kind of gas circuit structure of adjustable multistage load.
Background technology
Often need in the testing experiment to load different load, to satisfy diversified test request.At present common pressure testing apparatus generally realizes that by counterweight or spring that different size is set such equipment is regulated more complicated; The testing apparatus that adopts pneumatic scheme is also arranged, but in order to satisfy bigger adjustable load range, often need the components and parts of selecting for use range of regulation bigger, cost is higher, and precision is lower.
The utility model content
The applicant can not conveniently regulate shortcomings such as load at above-mentioned existing testing apparatus, a kind of gas circuit structure of simple in structure, easy to operate adjustable multistage load is provided, can carry out the flexible setting of load according to different test requests, thereby finish test efficiently.
The technical scheme that the utility model adopted is as follows:
A kind of gas circuit structure of adjustable multistage load, endpiece at pneumatic triple piece is provided with the multi-path joint, the branch road that its minute way outlet two-way at least in parallel respectively is connected in series by reduction valve and solenoid valve, be connected in the inlet of 3 position-5 way solenoid valve after each branch road gathers, the gas outlet of 3 position-5 way solenoid valve is connected to the rodless cavity and the rod chamber of cylinder by throttling valve.
The utility model adopts cylinder to realize to-and-fro movement, by pneumatic components and parts control rate and acting force, adopt multiple branch circuit combination in parallel to control air pressure, avoided selecting for use the pneumatic components and parts of single costliness, rational in infrastructure reliable, can regulate multistage load accurately and effectively.
Description of drawings
Fig. 1 is a pneumatic control schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
Pneumatic schematic diagram of the present utility model as shown in Figure 1, by rapid-acting coupling 101 the inside and outside gas circuit is communicated, pressurized air is at first by pneumatic triple piece 102, pneumatic triple piece 102 comprises air strainer, reduction valve, oil sprayer, it mainly acts on is the general pressure of adjusting in the gas circuit, filters the airborne mist of oil of compression simultaneously; Endpiece at pneumatic triple piece 102 is provided with four-way connection 103, the branch road that other three way outlets of four-way connection 103 three route reduction valve 104 in parallel respectively and normally closed solenoid valve 105 are connected in series, three road branch roads gather and are connected in the inlet of 3 position-5 way solenoid valve 107 at four-way 106, the direct action venthole of 3 position-5 way solenoid valve 107 is connected in the rodless cavity of cylinder 109 by throttling valve 108, and the reverse action venthole is connected in the rod chamber of cylinder 109 by throttling valve 108.
During actual the test, start TT﹠C system, on the control interface, parameters such as load, stroke, cycle index and speed are set, TT﹠C system is by the switching combination of the solenoid valve 105 on three branch roads of control, thereby input to the air-flow of 3 position-5 way solenoid valve 107 different pressures, in order to satisfy different control lever Tensile or Compressive Loading requirements.Switch the axis of the piston expanding-contracting action that can control cylinder by control 3 position-5 way solenoid valve 107 different paths.By regulating throttling valve 108, can be by regulating the movement velocity that the air-flow size is come the control cylinder piston.Can the Control Circulation number of times by counter.
The utility model can satisfy test request by parameter setting flexibly.With actual test event is example, solenoid valve 105, the first branch roads of opening first branch road, second branch road by TT﹠C system can provide the air pressure of 0.1MP, and second branch road can provide the air pressure of 0.4MP, the two-way air-flow gathers to 3 position-5 way solenoid valve 107, can satisfy the pulling force requirement of 400N.Counter is set to 100000 times.By regulating throttling valve 108 to satisfy 5 seconds/round-robin rate request.
More than describing is to explanation of the present utility model, it or not qualification to utility model, the utility model institute restricted portion is referring to claim, under the situation of spirit of the present utility model, the utility model can be done any type of modification, for example adopt similar components and parts to do simple the replacement, realize the course of action identical with the utility model; Perhaps the branch road more than the two-way at least is set, provides different air pressure in order to control at 3 position-5 way solenoid valve leading portion.
