Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valve operating tools, in particular to a manual operating device for an electromagnetic valve. Background Art

[0002] At present, the solenoid valve on the oil return tank has two modes of operation: electric operation and manual operation. The electric operation mode is generally used for normal start and stop, remote operation, etc.; the manual operation mode is mostly used in power outages, by pressing the valve core, using a pure mechanical circuit to throw in and out the lock spindle, throw in and out the start and stop valve, and the use scenarios are post-maintenance testing, emergency shutdown, etc. The seven solenoid valves are arranged horizontally and are of the same height.

[0003] The manual operation method has the following problems:

[0004] 1. The location of the solenoid valve is too high. After the speed regulator is modified, the length and width of the new return oil tank are 3800mm*1800mm and the height is 1390mm. Each solenoid valve is located on the upper part of the return oil tank and is blocked by a fence. It is necessary to climb to the upper part of the return oil tank with a ladder, which poses certain safety risks.

[0005] 2. The manually pressed valve core of the solenoid valve is small. The valve core of the solenoid valve is located at the dot in the center of the solenoid valve. It is necessary to carry a needle rod tool to press it. The valve core needs to be pressed for about 1 cm and has a small diameter. It is difficult and inconvenient to operate by hand.

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1 As shown, an embodiment of the utility model proposes a manual operating device for a solenoid valve, including a base 1, a connecting column 2, a cross bar 3 and a collar 4, wherein the base 1 is provided with a plurality of bolts 5, the connecting column 2 is rotatably mounted on the base 1, the cross bar 3 is transversely mounted on the top of the connecting column 2, the collar 4 is slidably connected to the cross bar 3, a thimble 6 is fixedly connected to the collar 4, and the thimble 6 is vertically arranged on the plane formed by the connecting column 2 and the cross bar 3.

[0021] When it is necessary to press the solenoid valve 12, the operator stands on the ground, fixes the base 1 on the oil return tank, slides the ring 4 across the railing, makes the ejector pin 6 of the ring 4 correspond to the valve core of the solenoid valve 12 to be operated, rotates the cross bar 3, makes the ejector pin 6 approach the valve core of the solenoid valve 12, and thus presses the valve core, which reduces the safety risk and makes the operation more convenient. Different valve cores can be pressed according to needs, which is easy to use.

[0022] In this embodiment, if Figure 2 As shown, the cross bar 3 is fixedly connected to the top of the connecting column 2, so that the cross bar 3 and the connecting column 2 form an L shape. The cross bar 3 and the plane where the solenoid valve 12 is located have an angle of 2% to 5%, which is convenient for the ejector pin 6 to press the valve core without interference.

[0023] In this embodiment, if Figure 1 As shown, the top of the connecting column 2 is symmetrically fixedly connected with two connecting ears 7, a connecting shaft 8 is installed on the connecting ear 7, the cross bar 3 is hinged on the connecting shaft 8, and the cross bar 3 is laterally limited to the top of the connecting column 2. The cross bar 3 can be turned 180 degrees on the connecting column 2, and the solenoid valve 12 on the other side can be pressed, so that two rows of solenoid valves 12 can be pressed, which is more convenient to use.

[0024] In this embodiment, if Figure 1 As shown, a plurality of positioning grooves 9 are provided on the top of the crossbar 3, and the positioning grooves 9 correspond to the position of the electromagnetic valve 12. When the collar 4 is located in the positioning grooves 9, the ejector pin 6 on the collar 4 corresponds to the position of the valve core of the electromagnetic valve 12. The collar 4 is slid to different positioning grooves 9 to position the ejector pin 6, so that the ejector pin 6 is pressed against the corresponding valve core to prevent the ejector pin 6 on the collar 4 from sliding.

[0025] In this embodiment, if Figure 1 As shown, a placement groove 10 is provided on one side of the positioning groove 9, and the number of the collars 4 is corresponding to the number of the solenoid valves 12. The collars 4 that do not need to be pressed are clamped in the placement groove 10, and the collars 4 that need to be pressed are clamped in the positioning groove 9 next to the placement groove 10, so as to quickly position the valve core that needs to be pressed.
