Abstract
The utility model relates to a pulse valve with a venturi tube structure, which comprises a guide part, a valve cover and a valve body, wherein the guide part, the valve cover and the valve body are connected in sequence; a spring is arranged in the valve cover, a diaphragm assembly is arranged on the connection part between the valve cover and the valve body; a venting channel is arranged in the valve body, adopts the venturi tube structure, and comprises a front retraction tube, a middle straight tube and a rear expansion tube. Compared with pulse valves in the prior art, the pulse valve has the advantages of being provided with the venting channel adopting the venturi tube structure, greatly improving ash-cleaning benefits, and the like.
Description
Technical field
The utility model relates to a kind of sentinel valve, especially relates to a kind of sentinel valve with the Venturi tube structure.
Background technique
The sentinel valve of band Venturi tube structure is a kind of of sentinel valve; Be mainly used in the sack cleaner; It utilizes variation of gas pressure to make pressurized gas in the gas bag (branch gas tank) jet in the air chamber of sack cleaner and make attached to the solid dust on the filtering material to break away from, be the crucial accessory of sack cleaner.Use treating flour dust and assembling sphere widely with every profession and trade.
The sentinel valve of the band Venturi tube structure of conventional is as shown in Figure 1, is made up of guide's part, valve gap, spring, diaphragm unit, valve body etc.Guide's part can directly be connected on the valve gap through screw; Also can be connected with valve gap through tracheae; Valve gap is connected spring, diaphragm unit and valve body through screw, and the inlet Connecting format of valve body is a flange arrangement, and the outlet of valve body is connected with the winding-up pipe; The outlet passageway that the winding-up air communication is crossed isometrical straight tube gets into the winding-up pipe, and stream condition is a turbulent condition.Cause the air-flow skewness of jetting to each filtrating equipment like this, instability.
The model utility content
The purpose of the utility model is exactly that in order to overcome the defective that above-mentioned existing technology exists a kind of outlet passageway to be provided be the Venturi tube structure, can improve the sentinel valve of the band Venturi tube structure of deashing benefit greatly.
The purpose of the utility model can realize through following technological scheme: a kind of sentinel valve with the Venturi tube structure; This sentinel valve comprises guide's part, valve gap and the valve body that connects successively, is provided with spring in the described valve gap, and the joint 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 the Venturi tube structure, this outlet passageway comprises preceding collapsible tube, middle part straight tube and back extension tube.
The undergauge of collapsible tube is 5 °～90 ° before described, but does not comprise 90 °.
The hole enlargement of described back extension tube is 5 °～90 °, but does not comprise 90 °.
Compared with prior art, the outlet passageway of the utility model is the Venturi tube structure, make gas that sentinel valve jets out more stabilized uniform be assigned on the deashing filtrating equipment, improve the deashing benefit greatly.
Description of drawings
Fig. 1 is the structural representation of tradition with the sentinel valve of band Venturi tube structure;
Fig. 2 is the structural representation of the sentinel valve of the utility model band Venturi tube structure.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment 1
As shown in Figure 2, a kind of sentinel valve with the Venturi tube structure, the improvement of on traditional sentinel valve, doing during this sentinel valve, it comprises guide's part 1, valve gap 2 and the valve body 5 that connects successively.Be provided with spring 3 in the valve gap 2, valve gap 2 is provided with diaphragm unit 4 with the joint of valve body 5, offers outlet passageway in the valve body 5, and outlet passageway is the Venturi tube structure, and this outlet passageway comprises preceding collapsible tube 51, middle part straight tube 52 and back extension tube 53.The undergauge α of preceding collapsible tube is chosen as 5 °～90 °, but does not comprise 90 °.The hole enlargement β of back extension tube is chosen as 5 °～90 °, but does not comprise 90 °.The undergauge α of the preceding collapsible tube of present embodiment is identical with back extension tube hole enlargement β's, is 30 °.The characteristics of Venturi tube structure are that the diameter shrinkage part airspeed that air communication is crossed the Venturi tube structure increases and the pressure reduction; Hole enlargement part airspeed through the Venturi tube structure reduces and the pressure increase, makes gas pressure that an equally distributed process is arranged simultaneously.Can make like this gas that sentinel valve jets out more stabilized uniform be assigned on the deashing filtrating equipment, improve the deashing benefit greatly.
Referring to Fig. 1, a kind of sentinel valve with the Venturi tube structure, the improvement of on traditional sentinel valve, doing during this sentinel valve, it comprises guide's part, valve gap and the valve body that connects successively.Be provided with spring in the valve gap, the joint of valve gap and valve body is provided with diaphragm unit, offers outlet passageway in the valve body, and outlet passageway is the Venturi tube structure, and this outlet passageway comprises preceding collapsible tube, middle part straight tube and back extension tube.The undergauge α of preceding collapsible tube is chosen as 5 °～90 °, but does not comprise 90 °.The hole enlargement β of back extension tube is chosen as 5 °～90 °, but does not comprise 90 °.The undergauge α of the preceding collapsible tube of present embodiment is different with back extension tube hole enlargement β's, and the undergauge α of preceding collapsible tube is 10 °.The hole enlargement β of back extension tube elects 20 ° as.
Claims (3)
1. sentinel valve with the Venturi tube structure; This sentinel valve comprises guide's part, valve gap and the valve body that connects successively, is provided with spring in the described valve gap, and the joint 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 the Venturi tube structure, this outlet passageway comprises preceding collapsible tube, middle part straight tube and the back extension tube that connects successively.
2. a kind of sentinel valve with the Venturi tube structure according to claim 1 is characterized in that, the undergauge of described preceding collapsible tube is 5 °～90 °, but does not comprise 90 °.
