Abstract

Embodiments of a solenoid valve are provided. The solenoid valve includes a solenoid portion with a detection device, a valve body, an armature assembly, and a detection plate. The armature assembly has a first end extending through the solenoid portion and a second end extending into the valve body. The detection plate is configured to interact with the detection device to produce a signal indicating whether the solenoid portion is installed on the valve body. The solenoid portion is disposed between the valve body and the detection plate.

Claims

1. A solenoid valve, comprising:

a solenoid portion, the solenoid portion including a detection device;

a valve body;

an armature assembly, the armature assembly having a first end extending through the solenoid portion and a second end extending into the valve body; and

a detection plate, the detection plate configured to interact with the detection device to produce a signal indicating whether the solenoid portion is installed on the valve body;

wherein the solenoid portion is disposed between the valve body and the detection plate.

2. The solenoid valve of claim 1, wherein the detection plate is rotatable about the armature assembly.

3. The solenoid valve of claim 2, wherein the detection plate is rotatable 360°

about the armature assembly.

4. The solenoid valve of claim 1, wherein the solenoid portion includes a depression adapted to receive at least a portion of the detection plate.

5. The solenoid valve of claim 1, wherein the detection device is a limit switch having a plunger, wherein the plunger is actuated by the detection plate to produce the signal.

6. The solenoid valve of claim 1, wherein the detection device is a light sensor.

7. The solenoid valve of claim 1, wherein the detection device and the detection plate interact using a proximity sensor on one of the detection device and the detection plate that senses the proximity of the other of the detection device and detection plate.

8. The solenoid valve of claim 1, wherein the detection device and the detection plate interact using an RFID sensor located on one of the detection device and the detection plate and an RFID chip located on the other of the detection device and the detection plate.

9. The solenoid valve of claim 1, further comprising a permanent magnet on the armature assembly such that the solenoid valve operates as a latching solenoid valve.

10. The solenoid valve of claim 1, wherein the solenoid valve is installed in a fire suppression or fire sprinkler system and wherein the solenoid valve is adapted to control the release of the fire suppressant fluid upon receiving a signal from a control unit of the fire suppression or fire sprinkler system.

11. A solenoid valve, comprising:

a valve body;

a solenoid portion, the solenoid portion being rotatable relative to the valve body to a first angular orientation; and

a rotatable plate, the rotatable plate being rotatable relative to the valve body to a second angular configuration;

wherein the solenoid portion is disposed between the valve body and the rotatable plate; and

wherein the second angular configuration is equal to the first angular configuration.

12. The solenoid valve of claim 11, wherein the rotatable plate can rotate to an angular orientation of 360°

relative to the valve body.

13. The solenoid valve of claim 11, wherein the solenoid portion includes a depression adapted to receive at least a portion of the rotatable plate.

14. The solenoid valve of claim 13, wherein the solenoid portion rotates together with the rotatable plate relative to the valve body.

15. The solenoid valve of claim 14, wherein the solenoid portion further comprises a detection device, the detection device interacting with the rotatable plate to produce a signal indicating whether the solenoid portion is installed on the valve body.

16. A solenoid valve, comprising:

a solenoid portion, the solenoid portion including a detection device;

a valve body;

an armature assembly, the armature assembly having a first end extending through the solenoid portion and a second end extending into the valve body;

a locking nut, the locking nut comprising;

a cylinder member having an interior bore adapted to engage the armature assembly; and

a ring member that engages the outer perimeter of the cylinder member, the ring member protruding from the surface of the cylinder member and the ring member being configured to retain a detection plate of the solenoid valve when the locking nut is removed from the solenoid valve.

17. The solenoid valve of claim 16, further comprising a circumferential groove around the cylinder member, wherein the ring member is seated in the circumferential groove.

18. The solenoid valve of claim 17, further comprising a circumferential ledge around the cylinder member, wherein the circumferential ledge is spatially disposed from the ring member at a distance equal to or greater than a thickness of the detection plate.

19. A solenoid valve, comprising:

a solenoid portion, the solenoid portion including a detection device;

a valve body;

an armature assembly, the armature assembly having a first end extending through the solenoid portion and a second end extending into the valve body;

a detection plate, the detection plate configured to interact with the detection device to produce a signal indicating whether the solenoid portion is installed on the valve body;
