Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulse valve technology, and in particular to an angle pulse valve. Background Technology
[0002] Angle pulse valves are mostly used in bag filters to clean the filter bags.
[0003] In practical applications, nozzles may fail due to wear, corrosion, or blockage caused by the working environment inside the dust collector. However, the nozzles and valve bodies of traditional pulse valves are mostly integrated designs or threaded connections, making the replacement process very cumbersome and inefficient. Furthermore, since a typical bag filter contains dozens or more valve bodies, the maintenance process of traditional pulse valves is also very complicated. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an angle pulse valve.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An angle pulse valve includes a valve body, a pair of inserts are installed at the bottom of the valve body to assemble a nozzle, and mating seats are provided on both sides of the nozzle. Slots are provided in the mating seats to connect the inserts. A limit block is rotatably installed on one side of the middle of the mating seat via a pin. A wedge block is provided at the bottom of the limit block and is fitted and snapped into the limit groove opened at the bottom of the insert.
[0007] The outer wall of the wedge block is equipped with a magnetic absorbing plate. When the wedge block is inserted into the limiting groove, the magnetic absorbing plate is magnetically connected to the magnetic sheet provided on the inner wall of the limiting groove.
[0008] In addition, a preferred structure is that the bottom of the valve body is provided with an air inlet pipe, which communicates with the inside of the valve body. A rubber ring is installed on the outside of the air inlet pipe, and when the valve body is connected to the nozzle, the nozzle and the rubber ring are pressed into contact.
[0009] In addition, a preferred structure is that insert blocks are installed on both sides away from the air inlet pipe, and limit grooves are formed on the outer side of the insert blocks.
[0010] Furthermore, in a preferred configuration, a spring is installed on the inner bottom wall of the slot, and when the valve body is connected to the nozzle, the insert block is pressed into contact with the spring.
[0011] In addition, a preferred structure is that a pressing wedge is installed at an angle on the upper part of the limiting block. In its natural state, the pressing wedge has a gap with the outer wall of the docking seat. When the valve body is connected to the nozzle, the pressing wedge still has a gap with the outer wall of the docking seat after being rotated and displaced.
[0012] In addition, a preferred structure is that a torsion spring is installed at the rotatable connection between the limiting block and the slot, and the torsion spring deforms when the limiting block rotates.
[0013] In addition, a preferred structure is that a rubber sleeve is installed on the outside of the docking seat, and the rubber sleeve covers the outside of the limiting block.
[0014] In addition, a preferred structure is that the nozzle has a groove in the middle to connect to the air pipe, and multiple sealing rings are installed on the inner wall of the groove. When the valve body is connected to the nozzle, the air pipe and the sealing rings are pressed together to achieve a seal.
[0015] The beneficial effects of this utility model are as follows:
[0016] In this invention, the nozzle is equipped with a magnetic self-locking mechanism consisting of a limiting block, a wedge block, and a magnetic plate. When the nozzle is connected to the valve body, the stability of the two is ensured by the slotted block locking and magnetic connection. During disassembly, the unlocking operation can be achieved simply by pressing the limiting block. The entire disassembly and assembly process is convenient and quick, and installation can be completed without the need for threaded connections, thus ensuring the maintenance efficiency of the pulse valve.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-5 An angle pulse valve includes a valve body 1. A pair of inserts 12 are installed at the bottom of the valve body 1 to assemble a nozzle 2. The nozzle 2 has docking seats 21 on both sides of its exterior. The docking seats 21 have slots 3 to connect the inserts 12. The nozzle 2 is connected to the valve body 1 through the docking seats 21.
[0025] A limiting block 4 is rotatably installed on one side of the middle part of the docking seat 21 via a pin. A wedge block 42 is provided at the bottom of the limiting block 4. The wedge block 42 is fitted and snapped into the limiting groove 121 opened at the bottom of the insert block 12.
[0026] Furthermore, a magnetic absorbing piece 44 is installed on the outer wall of the wedge block 42. When the wedge block 42 is inserted into the limiting groove 121, the magnetic absorbing piece 44 is magnetically connected to the magnetic piece 122 provided on the inner wall of the limiting groove 121.
[0027] The bottom of the valve body 1 is provided with an air inlet pipe 11, which is connected to the inside of the valve body 1. A rubber ring 6 is installed on the outside of the air inlet pipe 11. When the valve body 1 is connected to the nozzle 2, the nozzle 2 and the rubber ring 6 are pressed into contact.
[0028] Insert blocks 12 are installed on both sides away from the air inlet pipe 11, and limit grooves 121 are opened on the outer side of the insert blocks 12.
[0029] A spring 43 is installed on the inner bottom wall of the slot 3. When the valve body 1 is connected to the nozzle 2, the insert block 12 and the spring 43 are pressed into contact. The upward force provided by the spring 43 causes the limiting groove 121 to be firmly engaged with the wedge block 42.
[0030] The upper part of the limiting block 4 is inclined to install a pressing block 41. In its natural state, the pressing block 41 leaves a gap with the outer wall of the docking seat 21. When the valve body 1 is connected to the nozzle 2, the pressing block 41 still leaves a gap with the outer wall of the docking seat 21 after being rotated and displaced.
[0031] A torsion spring 5 is installed at the rotatable connection between the limiting block 4 and the slot 3. When the limiting block 4 rotates, the torsional force generated by the deformation of the torsion spring 5 causes the limiting block 4 to deflect inward to the slot 3, thereby causing the wedge block 42 to engage with the limiting groove 121.
[0032] A rubber sleeve 22 is installed on the outside of the docking seat 21. The rubber sleeve 22 covers the outside of the limiting block 4. The operator can press the internal limiting block 4 and pressing inclined block 41 through the rubber sleeve 22 without affecting the normal use of the equipment. The rubber sleeve 22 plays the role of isolating dust, which is easy to understand and will not be explained further.
[0033] The nozzle 2 has a slot in the middle to connect to the air pipe 11. Multiple sealing rings 23 are installed on the inner wall of the slot. When the valve body 1 is connected to the nozzle 2, the air pipe 11 and the sealing rings 23 are pressed together to achieve a seal.
[0034] In this embodiment, during the installation of the nozzle 2, the mating seats 21 on both sides of the nozzle 2 are aligned with the insert block 12 at the bottom of the valve body 1 and inserted for mating. At the same time, the air inlet pipe 11 at the bottom of the valve body 1 is inserted into the groove in the middle of the nozzle 2.
[0035] When the insert 12 is inserted into the slot 3 in the middle of the docking seat 21, the limiting block 4 inside the slot 3 is forced to rotate by the insertion and squeezing of the insert 12, while the bottom end of the insert 12 slides on the outer wall of the limiting block 4. At the same time, the spring 5 provided inside the slot 3 is pressed and contacted with the insert 12.
[0036] When the insert 12 is fully inserted into the slot 3, the limiting groove 121 on one side of the insert 12 corresponds to the wedge block 42 on one side of the limiting block 4. Under the torsional force of the torsion spring 5, the limiting block 4 drives the wedge block 42 to be inserted into the limiting groove 121. Due to the wedge structure, the locking and engaging effect between the wedge block 42 and the limiting groove 121 is effectively achieved.
[0037] Meanwhile, a magnetic absorbing piece 44 is provided on the outer side of the wedge block 42. The magnetic absorbing piece 44 will be attracted and connected to the magnetic piece 122 in the limiting groove 121, further improving the locking and snapping effect between the wedge block 42 and the limiting groove 121.
[0038] The torsion spring 5 deforms as the limiting block 4 rotates, thereby generating a torsional force opposite to the direction of rotation, which in turn drives the limiting block 4 to always be close to the insert block 12, ensuring the locking and engaging effect between the wedge block 42 and the limiting groove 121.
[0039] Furthermore, during the disassembly of nozzle 2, the operator only needs to press the upper part of the rubber sleeve 22 on the outside of the docking seat 21, so as to press the pressing inclined block 41 on the upper part of the limiting block 4, causing the limiting block 4 to rotate outward as a whole, and the wedge block 42 then disengages from the insert block 12. At this time, nozzle 2 is in a movable state and can be removed from valve body 1.
[0040] The rubber sleeve 22 is hollow in the middle and covers the limiting block 4. When subjected to pressing force, the rubber sleeve 22 deforms. This is easy to understand intuitively and will not be explained further.
[0041] In its natural state, the limit block 4 tilts and deflects towards the slot 3.
[0042] The quick-connect structure, composed of components such as limit blocks and wedge blocks, replaces the threaded connection mechanism of traditional connecting pipes, effectively improving the maintenance efficiency of the nozzle and ensuring sealing.
[0043] Valve body 1, i.e., the angle pulse valve, its specific operating principle, installation with the dust collector, and its internal structure are common knowledge to those skilled in the art and will not be explained further.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
