Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic pulse valves, in particular to an ultra-low dust removal right-angle electromagnetic pulse valve. Background Art

[0002] The electromagnetic pulse valve is a type of pulse valve, mainly used in bag dust collectors. It uses the change of gas pressure to make the compressed air in the air bag spray into the air chamber of the bag dust collector, and separate the solid dust attached to the filter material. It is a key component of the bag dust collector and is widely used in the dust control and collection fields of various industries.

[0003] When the pressure air bag and the dust cleaning device are relatively fixed, it is very difficult to rigidly connect the electromagnetic pulse valve to the pressure air bag outlet pipe and the dust cleaning device inlet through threads at the same time. In addition, the installation of the electromagnetic pulse valve for bag dust collector currently has the disadvantages of being inconvenient to disassemble and install, being unstable to install, and being easy to loosen. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides an ultra-low dust removal right-angle electromagnetic pulse valve, which overcomes the shortcomings of the existing technology and can effectively ensure the airtightness effect while ensuring the convenient installation of the air outlet joint of the air bag and the air inlet joint of the blow pipe.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] One end of the inner wall of the locking nut is provided with an internal thread, and the other end of the inner wall of the locking nut is provided with a raised ring. The outer surfaces of the input port and the output port are provided with annular grooves. One end of the locking nut is rotatably connected in the annular groove through the raised ring. The air outlet joint of the air bag and the air inlet joint of the blow pipe are both external threaded joints, and the other end of the locking nut is threadedly connected to the air outlet joint of the air bag and the air inlet joint of the blow pipe through internal threads.

[0009] Preferably, a sealing ring is fixedly installed on the contact surface between the valve body and the valve cover.

[0010] Preferably, a sealing gasket is provided on the side wall of the annular groove, and the sealing gasket contacts the side surface of the raised ring.

[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0019] Example 1, as Figure 1 As shown, an ultra-low dust removal right-angle electromagnetic pulse valve includes a pilot part 1, a valve cover 2, a valve body 3, a valve disc, an air bag 5 and a blowing pipe 6. The valve cover 2 is fixed to the valve body 3. The valve disc is driven by the pilot part 1 so that it can be movably connected to the valve body 3 up and down. A diaphragm is installed between the valve cover 2 and the valve body 3.

[0020] An input port 7 is provided on the side of the valve body 3, and an output port 8 is provided below the valve body 3. The valve disc movably contacts the output port 8. The input port 7 and the output port 8 are set at 90 degrees. The input port 7 is connected to the air bag 5 through a locking nut 9, and the output port 8 is connected to the blowing pipe 6 through a locking nut 9.

[0021] An internal thread is provided at one end of the inner wall of the locking nut 9, and a raised ring is provided at the other end of the inner wall of the locking nut 9. An annular groove is provided on the outer surfaces of the input port 7 and the output port 8. One end of the locking nut 9 is rotatably connected to the annular groove through the raised ring. The air outlet joint of the air bag 5 and the air inlet joint of the blow pipe 6 are both external threaded joints. The other end of the locking nut 9 is threadedly connected to the air outlet joint of the air bag 5 and the air inlet joint of the blow pipe 6 through an internal thread.

[0022] Working principle:

[0023] During installation, since the locking nut 9 can be rotated in the outer surfaces of the input port 7 and the output port 8 respectively through the raised ring, when connecting the air bag 5 and the blow pipe 6, the internal thread at the other end of the locking nut 9 can be directly used to rotate and connect with the air outlet joint of the air bag 5 and the air inlet joint of the blow pipe 6. During the entire process, it is only necessary to rotate the locking nut 9, and there is no need to rotate the air bag 5 and the blow pipe 6 to complete the installation of the air bag 5 and the blow pipe 6.

[0024] In this embodiment, a sealing gasket is provided on the sidewall of the annular groove, which contacts the side surface of the raised ring. Therefore, when the locking nut 9 is rotated, the pre-tightening force between the locking nut 9, the outlet connector of the air bag 5, and the inlet connector of the blowpipe 6 causes the raised ring of the locking nut 9 to tightly contact the sidewall of the annular groove, thereby effectively achieving a sealing effect through the sealing gasket.

[0025] Embodiment 2, as a further preferred embodiment of embodiment 1, a sealing ring is fixedly installed on the contact surface between the valve body 3 and the valve cover 2. The sealing ring is used to achieve a sealing effect on the entire electromagnetic pulse valve to prevent compressed air from leaking and affecting the pressure of the compressed air.

[0026] In the third embodiment, as a further preferred embodiment of the first embodiment, the blowing pipe 6 is fixedly mounted and connected to the dust collector via a support assembly. The support assembly includes a support base 12, a U-shaped plate 13 disposed above the support base 12, and fixing blocks 14 disposed at both ends of the U-shaped plate 13. The fixing blocks 14 have through holes formed therein, and fixing bolts 15 are disposed within the through holes. The fixing bolts 15 pass through the through holes and are threadedly connected to the support base 12.

[0027] Therefore, when installing the blow pipe 6, first install the support base 12 according to the position of the blow pipe 6, then place the blow pipe 6 on the support base 12, then reversely put the U-shaped plate 13 onto the blow pipe 6, and then connect and fix the U-shaped plate 13 to the support base 12 through the fixing bolts 15, so that the blow pipe 6 can be fixed through the U-shaped plate 13, thereby controlling the radial movement of the blow pipe 1.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
