Abstract
The invention relates to a right-angle pulse valve with a flange. The pulse valve comprises a pilot part, a valve cover and a valve body which are connected sequentially, wherein a spring is arranged in the valve cover; a diaphragm assembly is arranged at the joint of the valve cover and the valve body; and an air outlet channel is formed in the valve body, has a Venturi tube structure and comprises a front contraction tube, a middle part straight tube and a rear extension tube. Compared with the prior art, the right-angle pulse valve has the advantages that the air outlet channel has a Venturi tube structure, so that the ash removal effect can be improved greatly and the like.
Description
Technical field
The present invention relates to a kind of pulse valve, especially relate to the flanged formula pulse valve in a kind of right angle.
Background technology
The flanged formula pulse valve in right angle is a kind of of pulse valve, be mainly used in the sack cleaner, it utilizes the variation of gas pressure to make Compressed 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 is the crucial accessory of sack cleaner.Use widely treating flour dust and assembling sphere with every profession and trade.
The flanged formula pulse valve in right angle that tradition is commonly used is comprised of guide's part, valve gap, spring, diaphragm unit, valve body etc. as shown in Figure 1.Guide's part can directly be connected by screw on valve gap, also can be connected with valve gap by tracheae, valve gap is connected spring, diaphragm unit and valve body by screw, the entrance type of attachment of valve body is flange arrangement, the outlet of valve body is connected with injection tube, the winding-up air-flow enters injection tube by the outlet passageway of isometrical straight tube, and stream condition is turbulent condition.Cause like this air-flow skewness of jetting to each filter, unstable.
Summary of the invention
Purpose of the present invention is exactly that to provide a kind of outlet passageway in order to overcome the defective that above-mentioned prior art exists be venturi tube structure, can greatly improve the flanged formula pulse valve in right angle of deashing benefit.
Purpose of the present invention can be achieved through the following technical solutions: the flanged formula pulse valve in a kind of right angle, this pulse valve comprises guide's part, valve gap and the valve body that connects successively, be provided with spring in the described valve gap, the junction of described valve gap and valve body is provided with diaphragm unit, offer outlet passageway in the described valve body, it is characterized in that described outlet passageway is venturi tube structure, this outlet passageway comprises front collapsible tube, middle part straight tube and rear extension tube.
The undergauge of described front collapsible tube is 5 °～90 °, but does not comprise 90 °.
The hole enlargement of described rear extension tube is 5 °～90 °, but does not comprise 90 °.
Compared with prior art, outlet passageway of the present invention is venturi tube structure, makes more being assigned on the deashing filter of stable and uniform of pulse valve blowing gas out, greatly improves the deashing benefit.
Description of drawings
Fig. 1 is the structural representation that tradition is used the flanged formula pulse valve in right angle;
Fig. 2 is the structural representation of the flanged formula pulse valve in the utility model right angle.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment 1
As shown in Figure 2, the flanged formula pulse valve in a kind of right angle, the improvement of doing at traditional pulse valve during this pulse valve, it comprises guide's part 1, valve gap 2 and the valve body 3 that connects successively.Be provided with spring 3 in the valve gap 2, valve gap 2 is provided with diaphragm unit 4 with the junction of valve body 3, offers outlet passageway in the valve body 3, and outlet passageway is venturi tube structure, and this outlet passageway comprises front collapsible tube 51, middle part straight tube 52 and rear extension tube 53.The undergauge α of front collapsible tube is chosen as 5 °～90 °, but does not comprise 90 °.The hole enlargement β of rear extension tube is chosen as 5 °～90 °, but does not comprise 90 °.The undergauge α of the front collapsible tube of present embodiment is identical with rear extension tube hole enlargement β's, is 30 °.The characteristics of venturi tube structure are that air-flow increases and pressure decreased by the diameter shrinkage part air velocity of venturi tube structure; Hole enlargement part air velocity by venturi tube structure reduces and the pressure increase, makes simultaneously gas pressure that an equally distributed process is arranged.Can make so more being assigned on the deashing filter of stable and uniform of pulse valve blowing gas out, greatly improve the deashing benefit.
Embodiment 2
Referring to Fig. 1, the flanged formula pulse valve in a kind of right angle, the improvement of doing at traditional pulse valve during this pulse valve, it comprises guide's part, valve gap and the valve body that connects successively.Be provided with spring in the valve gap, the junction of valve gap and valve body is provided with diaphragm unit, offers outlet passageway in the valve body, and outlet passageway is venturi tube structure, and this outlet passageway comprises front collapsible tube, middle part straight tube and rear extension tube.The undergauge α of front collapsible tube is chosen as 5 °～90 °, but does not comprise 90 °.The hole enlargement β of rear extension tube is chosen as 5 °～90 °, but does not comprise 90 °.The undergauge α of the front collapsible tube of present embodiment is different with rear extension tube hole enlargement β's, and the undergauge α of front collapsible tube is 10 °.The hole enlargement β of rear extension tube elects 20 ° as.
Claims (3)
