Description
Technical field
The utility model relates to a kind of fast open form submerged sentinel valve, belongs to the pulse jet technical field.
Background technique
Present submerged sentinel valve adopts two diaphragm structures, mainly form by members such as solenoid valve, little valve body, Small diaphragm-piece, big valve body, big diaphragms, form first air chamber between little valve body and the Small diaphragm-piece, form second air chamber between big valve body and the big diaphragm, be provided with helical spring below the big valve body, pod apertures on the big valve body is arranged on the stiffening rib of big valve body, and two exhaust passages of big valve body are arranged on the same side of big valve cylinder-shaped groove.Because pulse jet class deduster is tending towards maximizing day by day, the requirement of paired pulses valve also improves day by day, and present impulse method exists the diaphragm cracky, diaphragm is opened shortcomings such as rapid inadequately, that winding-up tolerance is not enough.
Summary of the invention
The technical solution of the utility model provides a kind of sentinel valve that can open and close and strengthen winding-up tolerance rapidly.
In order to achieve the above object, the technical solution of the utility model has provided a kind of fast open form submerged sentinel valve, comprise solenoid valve, little valve body, Small diaphragm-piece, big valve body, big diaphragm and output tube are formed, it is characterized in that, little valve body and big valve body constitute by a circular valve disc and a cylindrical body, link as a whole by a conical section between valve disc and the cylindrical body, respectively open the groove of a circle in cylindrical upper and lower, the cylindrical body cross section of big valve body is identical with the cylindrical cross-section of little valve body, the spool of solenoid valve is installed in the groove on cylindrical body top of little valve body, little valve body lower portion valve disc joins by the bolt and the upper cylinder of big valve body, be provided with Small diaphragm-piece between little valve body and the big valve body, be provided with big diaphragm below the big valve body and push down output tube, be provided with spring between big valve body and the big diaphragm, spring is located in the cylindrical body lower recess of big valve body, spring is connected with the center of big diaphragm downwards, Small diaphragm-piece and little valve body form first air chamber, big diaphragm forms second air chamber with big valve body, having the exhaust passage at the cylindrical body center of little valve body communicates with first air chamber, the side of the cylindrical body upper grooves of little valve body has exhaust port and communicates with the exhaust passage, having gas port at the edge of the circular valve disc of little valve body communicates with first air chamber, in the cylindrical body upper grooves of big valve body, have the exhaust passage, cylindrical body side at big valve body has exhaust port, communicate with the exhaust passage, have gas port at the cylindrical body edge of big valve body and communicate, be provided with gas port at the edge of big diaphragm with the gas port and second air chamber.
Advantage of the present utility model has been to simplify the external structure of sentinel valve, has accelerated the keying speed of diaphragm, has reduced the resistance of sentinel valve inside, has increased the once tolerance of winding-up.
Description of drawings
A kind of fast open form submerged sentinel valve structural drawing that Fig. 1 provides for the utility model.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, be a kind of fast open form submerged sentinel valve that the utility model provides, comprise solenoid valve 6, little valve body 5, Small diaphragm-piece 4, big valve body 3, big diaphragm 1 and output tube 14.Little valve body 5 and big valve body 3 constitute by a circular valve disc and a cylindrical body, link as a whole by a conical section between valve disc and the cylindrical body, the groove of a circle is respectively opened in cylindrical upper and lower, and the cylindrical body cross section of big valve body 3 is identical with the cylindrical cross-section of little valve body.The spool of solenoid valve 6 is installed in the groove on cylindrical body top of little valve body 5, and little valve body 5 bottom valve discs join by the bolt and the upper cylinder of big valve body 3.Be provided with Small diaphragm-piece 4 between little valve body 5 and the big valve body 3, be provided with big diaphragm 1 below the valve body 3 greatly and push down output tube 14.Be provided with spring 2 between big valve body 3 and the big diaphragm 1, spring 2 is located in the cylindrical body lower recess of big valve body 3, and spring 2 is connected with the center of big diaphragm 1 downwards.Small diaphragm-piece 4 forms first air chamber with little valve body 5, and big diaphragm 1 forms second air chamber with big valve body 3.Having exhaust passage 8 at the cylindrical body center of little valve body 5 communicates with first air chamber, the side of the cylindrical body upper grooves of little valve body 5 has exhaust port 7 and communicates with exhaust passage 8, having gas port 9 at the edge of the circular valve disc of little valve body 5 communicates with first air chamber, in the cylindrical body upper grooves of big valve body 3, have exhaust passage 10, cylindrical body side at big valve body 3 has exhaust port 11, communicate with exhaust passage 10, the cylindrical body edge of big again valve body 3 has gas port 12 and communicates with the gas port 9 and second air chamber, and the edge of big diaphragm 1 is provided with gas port 13.
