DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: a new type of solenoid valve, comprising: a solenoid valve body 1, an electric control module 2 is fixedly installed on the side of the solenoid valve body 1, and the electric control module 2 is connected to a circuit wiring port 3;

[0022] The lower end of the solenoid valve body 1 is fixedly connected to the switch seat 4, the lower end of the switch seat 4 is fixedly connected to the valve body joint 6, and the valve body joint 6 is fixedly connected to the valve body 8;

[0023] The electromagnetic valve body 1 is provided with an electromagnetic coil, and the electromagnetic valve body 1 is provided with a fixing sleeve 12, the electromagnetic coil sleeve is arranged outside the fixing sleeve 12, the upper end of the fixing sleeve 12 is threadedly connected to the plug 11, and the plug 11 fixes the electromagnetic valve body 1 and the fixing sleeve 12;

[0024] A valve core 7 is slidably arranged in the fixed sleeve 12, a spring is arranged between the fixed sleeve 12 and the valve core 7, and the valve core 7 slides through the switch seat 4 and the valve body joint 6;

[0025] The electric control module 2 conducts electricity to the electromagnetic coil, so that the valve core 7 moves up and down. A valve plate is fixedly installed at the lower end of the valve core 7, and the valve plate seals or opens the passage between the valve body joint 6 and the valve body 8;

[0026] The lower end of the valve core 7 is integrally provided with an indented step 71, and the lower end of the indented step 71 is fixedly provided with an end head 72;

[0027] A manual rotary switch 5 for driving the valve core 7 to rise is provided on the side of the switch seat 4. The manual rotary switch 5 comprises a sealed bearing 53. The sealed bearing 53 is provided on the side wall of the switch seat 4. A rotating shaft is provided through the sealed bearing 53. The left end of the rotating shaft is fixedly connected to the knob 51. The right end surface of the knob 51 is provided with an annular limiting groove 511. A semicircular boss 54 is provided integrally at the right end of the rotating shaft.

[0028] The semicircular boss 54 acts on the concave step 71. When the arc surface of the semicircular boss 54 rotates upward, the arc surface of the semicircular boss 54 cooperates with the concave step 71 to lift the valve core 7, the spring is compressed, and the end 72 is separated from the valve body 8 and the valve body joint 6, thus realizing the passage of the valve body 8.

[0029] When the flat surface of the semicircular boss 54 rotates to the upper side, space is reserved for the concave step 71 to move downward, and at this time, the spring range causes the valve core 7 to move downward;

[0030] The fixing seat 52 is fixedly installed on the side of the switch seat 4, and the side of the fixing seat 52 is fixedly connected to the limiting pin 521, which is inserted into the limiting groove 511. Through the cooperation between the limiting groove 511 and the limiting pin 521, the rotation angle of the knob 51 is limited to 90°.

[0031] Working principle: Under normal conditions, when driven by electromagnetic force, the arc surface of the semicircular boss 54 faces upward, and the valve core 7 has space to fall. At this time, the valve body joint 6 and the valve body 8 form a passage, which is the passage state;

[0032] When the valve needs to be closed, the electric control module 2 conducts electricity to the electromagnetic coil, and the valve core 7 descends to block the passage between the valve body joint 6 and the valve body 8, thereby closing the valve;

[0033] When manual control is required, the knob 51 is rotated again to make the arc surface of the semicircular boss 54 turn upward. Synchronously, the valve core 7 moves up and disengages from the valve body joint 6 and the passage of the valve body 8 to achieve passage. At this time, the spring is compressed, and the rotating knob 51 is rotated again to make the flat mouth face upward. The spring resets to push the valve core 7 downward to close the valve.
