Description

Technical Field

[0001] This utility model relates to the field of solenoid valve technology, and more specifically, to a normally open solenoid valve that is easy to connect. Background Technology

[0002] Normally open solenoid valves are widely used in industrial automation, fluid control and other fields. Currently, the coil assembly and valve seat assembly of solenoid valves are mostly fixed by threads or bolts, requiring special tools and involving cumbersome procedures. Under long-term vibration, the bolts may loosen.

[0003] Therefore, there is an urgent need for a normally open solenoid valve that is simple in structure, easy to connect quickly, and has a foolproof function. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a normally open solenoid valve that is easy to connect. The snap-fit ​​structure simplifies the connection between the coil assembly and the valve core seat assembly, thereby improving installation efficiency and reliability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a normally open solenoid valve that is easy to connect includes a valve body, a coil assembly, and a normally open valve core seat assembly. The normally open valve core seat assembly includes a valve core tube. The coil assembly is provided with a connection hole for inserting the valve core tube. A stationary iron core is provided at the end of the valve core tube away from the valve body. A snap-fit ​​block is provided at the top of the stationary iron core. A snap-fit ​​ring is provided at the bottom of the snap-fit ​​block. A snap-fit ​​component is detachably connected to the snap-fit ​​ring. The coil assembly can be connected to the coil assembly through the connection between the snap-fit ​​component and the snap-fit ​​block.

[0006] The present invention is further configured such that a washer block is provided between the snap-fit ​​component and the coil assembly.

[0007] The present invention is further configured such that: the coil assembly includes a terminal block, and the terminal block is provided with a first insert, a second insert, and a foolproof block.

[0008] The present invention is further configured such that the snap-fit ​​component is a head stop clip.

[0009] In summary, this utility model has the following beneficial effects:

[0010] This invention utilizes the cooperation of a snap-fit ​​block and a retaining clip to connect the coil assembly to the valve core seat without tools, improving installation efficiency. Furthermore, the locking structure of the snap-fit ​​ring and snap-fit ​​component ensures a secure connection, preventing loosening due to long-term vibration. Attached Figure Description

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Example: A normally open solenoid valve that is easy to connect, such as Figure 1-3 As shown, a normally open solenoid valve that is easy to connect includes a valve body, a coil assembly, and a normally open valve core seat assembly. The normally open valve core seat assembly includes a valve core tube, with a stationary iron core at the end away from the valve body. A locking block is fixed to the top of the stationary iron core, and an annular locking ring is formed at the bottom of the locking block. The coil assembly has a connection hole for inserting the valve core tube, and a detachable retaining clip engages with the locking ring to achieve quick locking between the coil assembly and the valve core seat.

[0017] A gasket is provided between the snap-fit ​​connector and the coil assembly to enhance sealing and damping. The coil assembly also includes a terminal block with a built-in first insert, a second insert, and a foolproof block. The foolproof block limits the wiring direction and prevents incorrect connection.

[0018] During assembly, after the valve core tube is inserted into the connection hole of the coil assembly, the locking block on the top of the stationary iron core engages with the head retainer via its bottom locking ring, securing the coil assembly. During installation, first place the washer block onto the valve core tube, then press the head retainer into the locking ring; a "click" sound indicates successful locking. A foolproof block inside the terminal block ensures that the power connector can only be inserted in one direction, preventing incorrect connections.

[0019] This invention has a simple structure and is suitable for scenarios requiring frequent maintenance or rapid replacement.

[0020] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
