Abstract
The utility model discloses a compressive strength testing device of an electromagnetic pulse valve housing. The compressive strength testing device is characterized in that the compressive strength testing device comprises a pressure storing pot, that a pressure input pipe is disposed on the bottom of the pressure storing pot, that the pressure storing pot is connected with a water box via a pressure pump, that a pressure sensor is disposed on the pressure storing pot, that a displacement sensor 1 and a displacement sensor 2 are respectively disposed on two sides of the top of the pressure storing pot, that the displacement sensor 1, the displacement sensor 2, and the pressure sensor are connected with a control unit. When a tested valve body, valve cover, or the entire housing of a valve is fixed on the installing holes of the testing device, the testing heads of the displacement sensors are placed on the surface of the tested member (contact state). Then pressure is applied via an automatic water pump and thus water pressure in the pressure storing pot rises in order to make the tested member to sustain pressure. Water pressure is monitored by the pressure sensor. Deformation quantity of the tested member is acquired by an acquisition board via signals transmitted from the displacement sensors. And related data and figures are formed by a computer processing the signals and become basis of design and analysis of the electromagnetic pulse valve housing.
Description
Technical field
The utility model relates to a kind of electromagnetic pulse valve chest compression-strength testing device, belongs to the electromagnetic impulse valve technical field.
Background technology
Electromagnetic impulse valve is to utilize winding-up pressurized air to realize filter bag ash removal.Therefore electromagnetic impulse valve is when work, and whole valve chest is in pressured state.The distortion of pressure and valve chest also is the important leverage of safe handling electromagnetic impulse valve until the relation of damaging is the important parameter of electromagnetic impulse valve design, manufacturing.Prior art is that on puller system (pulling force or pressure) tests its intensity with the part valve body of valve chest and valve gap, and its test is just carried out under emulation mode, with actual operating position certain gap is arranged.Another kind method is with whole electromagnetic impulse valve injecting compressed air pressurization, tests the ability that it bears pressure, mainly is the force value of its leakage of test, because there is potential safety hazard in compressed-air actuated characteristic in the operating process.
Summary of the invention
Problem to be solved in the utility model provide a kind ofly can make things convenient for, the method for the compressive resistance of the test electromagnetic pulse valve chest of safety or the parts such as its valve body, lid, and can understand relation in different pressures and its distortion, leakage, damage, and automatically record and preserve related data.
In order to achieve the above object, the utility model provides a kind of electromagnetic pulse valve chest compression-strength testing device, it is characterized in that, comprises storage pressure pot, and storage presses pot bottom to be provided with the pressure input pipe, and the pressure input pipe is connected with water tank by forcing pump; Storage presses pot to be provided with pressure transducer; Storage presses the both sides at pot top to be respectively equipped with displacement transducer one, displacement transducer two, and displacement transducer one, displacement transducer two, pressure transducer are connected with control module respectively.
When the whole housing of tested valve body, valve gap or valve is fixed on the mounting hole of proving installation, the measuring head of displacement transducer is placed the surface (contact condition) of measured piece; Then by manually or automatically water pump pressurization, storage presses the hydraulic pressure of pot to raise, and makes the measured piece pressurized; Hydraulic pressure is by pressure transducer, and the deflection of measured piece sends signal by the collection plate collection by displacement transducer, forms related data, figure after computer is processed, and becomes the foundation of the design and analysis of electromagnetic pulse valve chest.
The utility model is compared with prior art: more convenient, safety, test pressured state are consistent with actual pressured state, and can record respectively the relation of pressure and distortion, leakage, damage.Process forming curves figure by computer, automatic printing and save data can be applied to product design and parts manufacturing.

Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
Embodiment
As shown in Figure 1, the structural representation of the electromagnetic pulse valve chest compression-strength testing device that provides for the utility model is installed in two groups of proving installations on the same control desk 10, and control desk 10 is equipped with computer, controller, collection plate.Every group of proving installation comprises that inside is filled with water and presses pot 4 as the storage of pressure medium, and storage presses pot 4 bottoms to be provided with pressure input pipe 6, and the end of pressure input pipe 6 is connected with the endpiece of forcing pump 7, and the entrance point of forcing pump 7 is connected with water tank 8.Storage is pressed on the pot 4 pressure transducer 3 is installed, for detection of the pressure in the storage pressure pot 4.Storage presses the left and right sides of pot 4 to be respectively equipped with ear, left and right ear top is installation position displacement sensor 1, displacement transducer 25 respectively, and displacement transducer 1, displacement transducer 25, pressure transducer 3 are connected with the control module of control desk 10 by wire 9 respectively.Storage is pressed on the pot 4 and is had mounting hole, is used for installing and fixing electromagnetic impulse valve 2.Two groups of proving installations share a forcing pump 7 and water tank 8, economize on resources.
Test process: electromagnetic impulse valve 2 is fixed on storage presses pot 4 tops, electromagnetic impulse valve 2 and storage are pressed between the pot 4 form enclosure space; The measuring head of displacement transducer 1, displacement transducer 25 is placed respectively the both sides on electromagnetic impulse valve 2 surfaces, be contact condition and get final product, and with the zero setting of displacement display; Then by forcing pump 7 pressurizations, make storage press the hydraulic pressure in the pot 4 to raise, make electromagnetic impulse valve 2 pressurizeds; Hydraulic pressure is monitored by pressure transducer 3; The signal that the deflection of electromagnetic impulse valve 2 sends by displacement transducer 1, displacement transducer 25 forms related data, figure by the collection plate collection after computer is processed, become the foundation of the design and analysis of electromagnetic pulse valve chest.After the measured piece distortion, adjustable pressure descends, behind displacement transducer 1, displacement transducer 25 reflection pressure drops, whether displacement recovers (part is recovered or full recovery), the data that obtain from test are revised design, improve manufacturing process, thereby obtain best product.
