Abstract
The utility model discloses a double diaphragm pulse valve which mainly comprises a valve body, a valve seat and a built-in diaphragm connected through the electromagnetic valve, wherein, the valve body is provided inside with two air chambers communicated through air holes, the air chamber is provided inside with a diaphragm connected through a spring, a distributing air discharge hole communicated with the air chamber is arranged in the valve body which is provided with the rounding air inlet hole, the air blowing hole on the valve seat is connected with a blowing tube, the diaphragm is controlled by the electromagnetic valve to blow out the air current in the pulse type. The utility model is applicable for the self-control dust cleaning of the dust catcher in the metallurgy, concrete, chemistry, mining, mechanics, pharmacy and food processing industries or the like.
Description
The utility model relates to a kind of pair of diaphragm pulse valve, belongs to the gas valve technical field, is particularly useful for the operation of industrial pulse jet cleaning and filtering.
Dedusting at industrial filter often needs the reverse air pressure that applies that dust is blown off, require valve also to pass through a large amount of gases fast in very fast unlatching, 96192195.1 " gas valve of conveying gas pulse and method " discloses a kind of diaphragm type gas valve, diaphragm folding of electromagnetic valve by attachment hole realizes the air-flow ejection, the shortcoming of this technological scheme is diaphragm moulding complexity, it is high that material is required, and it is also inconvenient that valve inner also will be provided with assembling such as guiding device.
The purpose of this utility model is to provide a kind of pair of diaphragm pulse valve, makes its pulsed ejection air-flow with solenoid valve controlling diaphragm sheet.
The technical solution of the utility model is achieved in that this pair of its basic structure of diaphragm pulse valve is the valve body that is connected by solenoid valve, valve seat and built-in diaphragm constitute, two air chambers that are communicated with by pore are set in the described valve body, the diaphragm that spring connects is set in the air chamber, the separation panel pore that valve body setting is communicated with air chamber, valve body be provided with around suction port, the puff prot on the valve seat connects the winding-up pipe.
The diaphragm arrangement of described pair of diaphragm pulse valve is between valve body.
The diaphragm arrangement balance pore of described pair of diaphragm pulse valve.
The solenoid valve inlet hole of described pair of diaphragm pulse valve places the top of diaphragm spring.
The solenoid valve of described pair of diaphragm pulse valve is provided with exhaust port.
The design of the two air chambers of the utility model and two diaphragms makes valve opening and closing accurate rapidly, long service life, the pulsed gas flow of ejection is explosive strong, be applicable to the dust of industry cleaning and filterings such as metallurgy, cement, chemical industry, mine, machinery, pharmacy, grain processing, under 200-300 ℃ of condition, use the operation of nitrogen blowback automatic control deashing as the blast furnace gas sack cleaner.
Describe technology contents of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is two diaphragm pulse valve cross-section structure (opening state) schematic representation
Fig. 2 is that two diaphragm pulse valves and gas tank, winding-up are managed among the connection diagram figure: 1, solenoid valve 2, electromagnetic valve core 3, exhaust port 4, valve body 5, spring 6, diaphragm 7, shunting pore 8, air chamber 9, diaphragm 10, valve seat 11, air chamber 12, pore 13, spring 14, valve body 15, valve body 16, balance pore 17, suction port 18, puff prot 19 winding-up pipes 20, gas tank
Working principle of the present utility model is as shown in Figure 2: the valve body 14,15 of two diaphragm pulse valves is connected on the gas tank 20 by flange, and the winding-up pipe 19 that valve seat connects passes from gas tank and enters in the filter box-body; The air chamber 11 of shown in Figure 1 pair of diaphragm pulse valve is communicated with air chamber 8 by pore 12, in the valve closing position, and the pressure balance of air chamber 11, air chamber 8 and gas tank 20, diaphragm 9 withstands on puff prot 18 places of valve seat 10 by spring 13; When making solenoid valve exhaust port 3 be in communication with the outside air chamber 11 upper pressure, solenoid valve 1 unlatching reduces, diaphragm 6 lifts, air chamber 8 is communicated with the shunting pore 7 of air chamber 11 by pore 12, the pressure of air chamber 8 reduces, the pressure of gas tank 20 is about to diaphragm 9 jack-up, and air-flow immediately enters 19 ejections of winding-up pipe by suction port 9; When closed electromagnetic valve, upper diaphragm 6 falls and air chamber 11 is led to the opening of shunting pore 7 and blocks, air chamber 8 pressure recovery balances, and diaphragm 9 falls 18 closures of the puff prot on the valve seat 10, forms a pulse interval.The pressure of balance pore 16 air chamber when remaining on valve closes also is set on the diaphragm.The design of this pair of two air chamber interlocks of diaphragm can utilize the solenoid valve of smaller power to drive big puff prot valve working, and the folding of solenoid valve realizes by control instrument.
