Description
Technical Field
The invention relates to the technical field of electromagnetic valves, in particular to an electromagnetic valve with a quick-connection water nozzle.
Background
A solenoid valve is an electromechanical operated valve. Solenoid valves are commonly used to adjust parameters such as direction, flow rate and speed of liquids.

A gap exists at the joint of the water nozzle of the electromagnetic valve and the pipe body of the electromagnetic valve, so that liquid seeps out of the gap (namely, a liquid leakage phenomenon occurs).

As shown in FIG. 1, the present invention discloses a solenoid valve 10 with a quick-connect water nozzle, which comprises a solenoid valve body 20 and a water nozzle device 30 connected with the solenoid valve body 20.
However, the water nozzle of the conventional solenoid valve is connected to the pipe body of the solenoid valve by a screwing method or an interference fit method. When the screwing mode is adopted, on one hand, a certain time is needed for screwing; on the other hand, the screwing method has high requirements on the matching precision between the threads; while also requiring assembly personnel to screw in place. The gap is easy to exist at the connection position of the water nozzle of the magnetic valve and the pipe body of the magnetic valve due to the fact that workers cannot screw the water nozzle to the position or the matching precision among threads is not high enough in the assembling process. And thus, the liquid seeps out of the gap (i.e., a liquid leakage phenomenon occurs). When the interference fit mode is adopted, on one hand, the assembly implementation difficulty of the interference fit is high, and the required time is long; on the other hand, the size precision requirement of the water injection well choke of solenoid valve and the body of solenoid valve at the junction is high to interference fit's mode. The water nozzle of the electromagnetic valve is difficult to assemble or a gap exists at the joint of the water nozzle of the electromagnetic valve and the pipe body of the electromagnetic valve after the assembly. A gap exists at the joint of the water nozzle of the electromagnetic valve and the pipe body of the electromagnetic valve, so that liquid seeps out of the gap (namely, a liquid leakage phenomenon occurs).
As shown in fig. 2, specifically, the water nozzle device 30 includes: a housing assembly 310, a resilient return assembly 320, and an circumscribing conduit grip 330.

The water flow conductor 322, the intermediate guide 323 and the pipe clamp are movably received in the receiving chamber 313. The return elastic member 321 serves to provide a direct elastic force to the water flow conductor 322 so that the water flow conductor 322 can move relative to the intermediate guide member 323.
As shown in fig. 2, the outer pipe grip 330 has a grip 331, the water outlet 315 has an arc-shaped guide surface 317 engaged with the grip 331, the return elastic member 321 serves to provide a direct elastic force to the water flow conducting member 322, and the water flow conducting member 322 provides an indirect elastic force to the outer pipe grip 330 through the intermediate guide member 323, so that the grip 331 is expanded away from the water outlet 315, and the grip 331 is contracted near the water outlet 315.
Referring to fig. 1 and 2, it should be further explained that the solenoid valve 10 with the quick-connection water nozzle includes a solenoid valve body 20 and a water nozzle device 30 communicated with the solenoid valve body 20. The accommodating component 310 of the water nozzle device 30 includes a fixed pipe sleeve 311 and a movable pipe sleeve 312, the fixed pipe sleeve 311 is fixed on the solenoid valve body 20, the movable pipe sleeve 312 is movably connected with the fixed pipe sleeve 311 to form an accommodating cavity 313, and the accommodating cavity 313 is communicated with a water pumping cavity (not shown) of the solenoid valve body 20. The stationary sleeve 311 has a water inlet 314 and the movable sleeve 312 has a water outlet 315. The water flow in the water pumping cavity of the solenoid valve body 20 enters the accommodating cavity 313 from the water inlet 314 of the fixed pipe sleeve 311 and then flows out from the water outlet 315 of the movable pipe sleeve 312.
The structure of the water nozzle device 30 will be described in detail as follows:
as shown in fig. 2, the water nozzle device 30 includes: the receiving assembly 310, the elastic restoring assembly 320, the external pipe gripper 330 and the external pipe 340.
As shown in fig. 2, the housing assembly 310 includes a fixed sleeve 311 and a movable sleeve 312. The fixed sleeve 311 is fixed on the solenoid valve body 20, the movable sleeve 312 is movably connected with the fixed sleeve 311 to form a containing cavity 313, and the containing cavity 313 is communicated with a water pumping cavity of the solenoid valve body 20. The fixed pipe sleeve 311 is provided with a water inlet 314, the movable pipe sleeve 312 is provided with a water outlet 315, the water inlet 314 is communicated with the solenoid valve body 20, and the water outlet 315 is communicated with the external pipeline 340. In this embodiment, the movable sleeve 312 and the fixed sleeve 311 are connected by screwing. Of course, the movable connection between the movable sleeve 312 and the fixed sleeve 311 is not limited to a screw connection, and in other embodiments, the movable sleeve 312 and the fixed sleeve 311 may be connected by a snap connection or an interference fit connection.
As shown in fig. 2, the elastic restoring assembly 320 includes a restoring elastic member 321, a water flow transmission member 322, and an intermediate guide member 323. The water flow conducting member 322 is movably sleeved on the inner side wall of the middle guiding member 323, and the external pipeline gripping member 330 is movably sleeved on the outer side wall of the middle guiding member 323. The water flow conductor 322, the intermediate guide 323 and the pipe clamp are movably received in the receiving chamber 313. The return elastic member 321 is used to provide a direct elastic force to the water flow conducting member 322, so that the water flow conducting member 322 can move relative to the intermediate guiding member 323, and the water flow conducting member 322 obtains a tendency of returning to the position close to the water gap. In addition, the return elastic member 321 serves to provide a direct elastic force to the water flow conducting member 322, and the water flow conducting member 322 provides an indirect elastic force to the pipe grip through the intermediate guide member 323, so that the pipe grip obtains a tendency to return to the vicinity of the water outlet 315, and of course, the intermediate guide member 323 also obtains a tendency to return to the vicinity of the water outlet 315.
As shown in fig. 2, the return elastic member 321 has a spring structure. Two ends of the elastic restoring member 321 are respectively provided with an annular gasket 324, one end of the elastic restoring member 321 is fixed on the inner wall of the accommodating cavity 313 through the annular gasket 324, and the other end is connected with the water flow conducting member 322 through the annular gasket 324. The return elastic member 321 is used to provide a direct elastic force to the water flow conducting member 322, so that the water flow conducting member 322 can move relative to the intermediate guiding member 323, and the water flow conducting member 322 obtains a tendency of returning to the position close to the water gap. It should be noted that the provision of the annular gasket 324 is essential, on the one hand, to optimize the connection between the elastic return element 321 and the inner wall of the housing 313 and the connection between the elastic return element 321 and the water flow conducting element 322, and on the other hand, to avoid obstructing the water flow.
As shown in fig. 2 and 4, the outer sidewall of the middle guide 323 is provided with an insertion limiting ring 325, the inner sidewall of the receiving cavity 313 is provided with an insertion limiting step 316, and the insertion limiting ring 325 of the middle guide 323 abuts against or separates from the insertion limiting step 316 of the receiving cavity 313. When the external connection pipe 340 enters the receiving cavity 313 under the action of external force and is pressed and held on the middle guide part 323, the middle guide part 323 slides in the direction away from the water outlet 315 until the insertion limiting ring 325 of the middle guide part 323 abuts against the insertion limiting step 316 of the receiving cavity 313. At this time, even if the external force still exists, the intermediate guide 323 cannot slide further in the direction away from the water outlet 315. When the external force is stopped being applied to the external pipe 340, the water flow conducting member 322, the middle guiding member 323 and the external pipe 340 are reset to the direction close to the water outlet 315 under the elastic force of the reset elastic member 321, so that the insertion limiting ring 325 of the middle guiding member 323 is separated from the insertion limiting step 316 of the accommodating cavity 313.
As shown in fig. 4, the circumscribing pipe gripper 330 has a gripping portion 331, the gripping portion 331 has a plurality of gripping blocks 332, and the gripping blocks 332 have an arc-shaped block structure. The plurality of gripping blocks 332 are distributed in an annular array centered on the central axis of the gripping part 331, and a gap 333 is provided between two adjacent gripping blocks 332.
As shown in fig. 2, the water outlet 315 has an arc-shaped guide surface 317 engaged with the grip 331, the return elastic member 321 is used to provide a direct elastic force to the water flow conducting member 322, and the water flow conducting member 322 provides an indirect elastic force to the circumscribed pipe grip 330 through the intermediate guide member 323, so that the grip 331 is expanded away from the water outlet 315, and the grip 331 is contracted close to the water outlet 315.
As shown in fig. 2, the outer side wall of the circumscribed pipe 340 is provided with a slip-off preventing ring 341, the slip-off preventing ring 341 has an inclined guide surface 342, and the slip-off preventing ring 341 of the circumscribed pipe 340 is caught between the intermediate guide 323 and the grip 331.
Referring to fig. 2, 3 and 4, it should be noted that the water outlet 315 has an arc-shaped guiding surface 317 cooperating with the grip 331, the grip 331 has a plurality of grip blocks 332, and a gap 333 is formed between two adjacent grip blocks 332, which is very necessary. The analysis was as follows: before the water nozzle device 30 is connected to the external pipe 340, the external pipe gripping member 330 tends to be restored toward the water outlet 315 under the elastic force of the restoring elastic member 321. Further, since the water outlet 315 has the arc-shaped guide surface 317 engaged with the grip 331, the grip 331 obtains a tendency to contract when approaching the water outlet 315. Also, the grip 331 has a plurality of grip blocks 332 with a gap 333 between adjacent two grip blocks 332, so that the grip 331 has a gripping action when contracted, thereby gripping the anti-slip ring 341 of the outer connecting pipe 340 and finally stably connecting the outer connecting pipe 340 with the outer pipe grip 330.
As shown in fig. 2 and 4, it should be further explained that the inclined guide surface 342 of the anti-slip ring 341 is also necessary. The analysis was as follows: when the external pipe 340 enters the receiving cavity 313 under the action of external force, the inclined guide surface 342 of the anti-drop ring 341 contacts with the grip 331, and the external force acts on the external pipe grip 330 through the external pipe 340, so that the external pipe grip 330 slides in the direction away from the water outlet 315. Further, since the water outlet 315 has the arc-shaped guide surface 317 engaged with the grip portion 331 and the drop-off prevention ring 341 has the inclined guide surface 342, when the circumscribed pipe grip 330 is slid in a direction away from the water outlet 315, the grip portion 331 is slid in a direction away from the water outlet 315 along the arc-shaped guide surface 317 and the inclined guide surface 342 smoothly pushes the grip portion 331 apart.
As shown in fig. 4, it should be further noted that the gripping block 332 is an arc-shaped block structure, so that the gripping force of the gripping portion 331 is better, and the grip of the anti-slip ring 341 is firmer.
As shown in fig. 2 and fig. 3, the water flow conducting element 322 has a sealing abutting end surface 326, the external pipe 340 has a sealing pressing end surface 343, and the sealing pressing end surface 343 and the sealing abutting end surface 326 are attached to each other. In addition, the receiving cavity 313, the water flow conducting element 322 and the external pipe 340 form a through water flow channel 350, so that the water flow can flow through the water nozzle device 30 quickly and directly after coming out from the water pumping cavity of the solenoid valve body 20.
As shown in fig. 2, it should be noted that a design in which the seal pressing end face 343 and the seal abutting end face 326 abut against each other is necessary. The reason is that: when the anti-slip ring 341 of the external pipe is engaged between the middle guide 323 and the grip 331 and the external pipe 340 stops applying the external force, the water flow conducting member 322 moves relative to the middle guide 323 (i.e., the water flow conducting member 322 is reset toward the water outlet 315) under the elastic force of the reset elastic member 321. Meanwhile, the anti-drop ring 341 of the external pipe 340 is clamped between the middle guide part 323 and the grip part 331, so that the sealing pressing end face 343 and the sealing abutting end face 326 are tightly attached to each other, and the water flow channel 350 formed by the accommodating cavity 313, the water flow conducting part 322 and the external pipe 340 is further enabled to effectively avoid the water leakage situation.
Referring to fig. 2, fig. 3 and fig. 4 together, the operation principle of the electromagnetic valve 10 with the quick-connect water nozzle of the present invention is as follows:
when the external pipe 340 enters the receiving cavity 313 under the action of external force, firstly, the inclined guide surface 342 of the anti-drop ring 341 contacts with the grip 331, and the external force acts on the external pipe grip 330 through the external pipe 340, so that the external pipe grip 330 slides in the direction away from the water outlet 315; since the water outlet 315 has the arc-shaped guide surface 317 engaged with the grip 331 and the drop-off prevention ring 341 has the inclined guide surface 342, when the circumscribed-pipe grip 330 is slid in a direction away from the water outlet 315, the grip 331 is slid in a direction away from the water outlet 315 along the arc-shaped guide surface 317 and the inclined guide surface 342 keeps the grip 331 pushed open;
at the same time, the intermediate guide 323 and the water flow conductor 322 slide in the direction away from the water outlet 315 by the indirect action of the external force. Then, under the continued action of the external force, the grip 331 is further opened by the inclined guide surface 342 so that the escape prevention ring 341 of the outer pipe 340 is completely introduced into the outer pipe grip 330; if the external force continues to act on the external pipe 340, the sealing pressing end face 343 of the external pipe 340 is accurately attached to the sealing abutting end face 326 under the guiding action of the middle guiding member 323, and the inclined guiding surface 342 of the anti-drop ring 341 abuts against the middle guiding member 323; meanwhile, the middle guide part 323 and the water flow conducting part 322 continue to slide towards the direction away from the water outlet 315 together until the insertion limiting ring 325 of the middle guide part 323 abuts against the insertion limiting step 316 of the accommodating cavity 313;
stopping applying external force to the external pipeline when the inserting limit ring 325 of the middle guide part 323 is abutted against the inserting limit step 316 of the accommodating cavity 313; at this time, under the elastic force of the restoring elastic member 321, the water flow conducting member 322, the middle guide member 323, the external pipe gripping member 330 and the external pipe 340 are restored together in a direction close to the water outlet 315; during the resetting process of the water flow conducting piece 322, the middle guiding piece 323, the external pipeline gripping piece 330 and the external pipeline 340, the insertion limiting ring 325 of the middle guiding piece 323 is separated from the insertion limiting step 316 of the accommodating cavity 313, and the gripping part 331 of the external pipeline gripping piece 330 slides and shrinks towards the direction close to the water outlet 315 along the arc-shaped guiding surface 317;
when the external pipeline gripping member 330 is completely reset to the water outlet 315, the external anti-drop ring 341 is clamped between the middle guide member 323 and the gripping part 331, and at this time, the gripping part 331 firmly grips the anti-drop ring 341 of the external pipeline 340;
meanwhile, the elastic restoring member 321 provides a direct elastic force for the water flow conducting member 322, so that the water flow conducting member 322 can move relative to the middle guiding member 323, and further, the sealing abutting end surface 326 of the water flow conducting member 322 is tightly attached to the sealing pressing end surface 343 of the external pipe 340, so that the water flow channel 350 formed by the accommodating cavity 313, the water flow conducting member 322 and the external pipe 340 is effectively prevented from leaking water.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
