Abstract
The invention relates to a pulse valve performance online detecting device. The pulse valve performance online detecting device comprises a pressure tapping assembly, a pressure sensor and a data acquisition display unit; the pressure tapping assembly is mounted on a pulse valve and is communicated with a venting hole of the pulse valve; a pressure sensor mounting hole is arranged on the pressure tapping assembly; the pressure sensor is arranged in the pressure sensor mounting hole of the pressure tapping assembly and is connected with the data acquiring display unit; the pressure sensor is used for acquiring pressure signals on the venting hole of the pulse valve and transmitting the pressure signals to the data acquiring display unit; and the data acquiring display is used for receiving the injection pressure variation data of the pulse valve and displaying the injection pressure variation data in form of curves. Compared with the prior art, the pulse valve performance online detecting device provided by the invention has the advantage that various performance indexes of the pulse valve can be accurately determined online.
Description
Technical field
The present invention relates to a kind of pulse valve pick-up unit, especially relate to a kind of pulse valve performance on-line measuring device.
Background technology
Pulse valve mainly use with sack cleaner in, it utilizes the variation of gaseous tension to make pressure gas in the gas bag (minute gas tank) jet in the air chamber of sack cleaner and the solid dust that is attached on the filtering material is broken away from, and the purpose that reaches deashing or collection is the crucial accessory of sack cleaner.Use widely treating flour dust and assembling sphere with every profession and trade.
The pulse valve performance test of custom is normally carried out at the special detection device of manufacturer; test pressure point is arranged on the outlet of pulse valve; property indices by paired pulses valve behind the collection top hole pressure change curve is judged; after if pulse valve is installed to the fly-ash separator scene; carry out Performance Detection can only shut down the dismounting pulse valve after censorship; need so very large workload; and cause the loss of applying unit, and can not reach the purpose that the pulse valve runnability is observed in online detection.
Summary of the invention
Purpose of the present invention be exactly provide a kind of in order to overcome the defective that above-mentioned prior art exists and measure conveniently, pulse valve performance on-line measuring device that measuring accuracy is high.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of pulse valve performance on-line measuring device, it is characterized in that, comprise pressure assembly, pressure transducer, data acquisition display unit, described pressure assembly is installed on the pulse valve and with the vent hole of pulse valve and is communicated with, described pressure assembly is provided with the pressure transducer mounting hole, described pressure transducer is located in the pressure transducer mounting hole of pressure assembly, and described pressure transducer is connected with the data acquisition display unit;
Pressure signal on the described pressure transducer acquisition pulse valve vent hole, and be transferred to the data acquisition display unit, the data acquisition display unit obtains pulse valve blowing pressure delta data and shows with curve form.
Described pressure assembly comprises fixed support, pressure port, and described pressure port is located on the vent hole of pulse valve, and is communicated with the pressure transducer mounting hole.
Described fixed support is provided with adjusting bolt, setting nut and trip bolt.
Compared with prior art, the present invention has the following advantages:
Need not shut down the dismounting pulse valve, judge exactly online the property indices of pulse valve, have measure convenient, measuring accuracy is high.
Description of drawings
Fig. 1 is structural representation of the present invention;
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1 and Figure 2, a kind of pulse valve performance on-line measuring device, comprise pressure assembly a, pressure transducer b, data acquisition display unit c, described pressure assembly a is installed on the pulse valve and with the vent hole of pulse valve and is communicated with, described pressure assembly a is provided with the pressure transducer mounting hole, described pressure transducer b is located in the pressure transducer mounting hole of pressure assembly, and described pressure transducer b is connected with data acquisition display unit c;
Pressure signal on the described pressure transducer b acquisition pulse valve vent hole, and be transferred to data acquisition display unit c, data acquisition display unit c obtains pulse valve blowing pressure delta data and shows with curve form.
Described pressure assembly a comprises fixed support, pressure port a1, and described pressure port a1 is located on the vent hole of pulse valve, and is communicated with the pressure transducer mounting hole.Described fixed support is provided with adjusting bolt a2, setting nut a3 and trip bolt a4.
Pulse valve is comprised of guide's part 1, bonnet, 2, bottom flange 5, spring 3, upper diaphragm assembly 4, lower diaphragm unit 6, valve body 7, seal 8 etc. as shown in Figure 3.Characteristic according to pulse valve, before pulse valve is opened because upper diaphragm assembly 4, lower diaphragm unit 6 airtight, pulse valve relief port I and outlet IV airless are discharged, at present the throttle orifice V passage of diaphragm unit 6 is come round upper cavity II and lower chamber III together, thereby the air pressure of pressure gas is identical in two cavitys.When pulse valve was opened, the pressure gas of upper cavity II discharged from relief port I, and the pressure gas of lower chamber III discharges from outlet IV; After pulse signal ends afterpulse valve cut out, relief port I and outlet IV got back to again previous status.Can think that thus the pressure signal that collects from relief port I can indirectly reflect trend and state that outlet IV pressure changes, the pressure signal that collects by analysis relief port I can reflect the parameters such as the switch performance, pressure peak variation of pulse valve equally.
