Detailed Description
The construction and operation of the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, the dual-mode parking electromagnetic valve mainly comprises a spring seat 1, a spring 2, a steel ball 3, an iron core seat 4, a first bushing 5, a coil 6, a coil bracket 7, a shell 8, a disc spring 9, a first cylindrical pin 10, a locking nut 11, an iron core blocking plug 12, a second bushing 13, an O-shaped sealing ring 14, an iron core 15, an adjusting rod 16, an ejector rod 17, a second cylindrical pin 18 and other parts.
The spring seat 1 and the iron core seat 4 are connected by screw threads, a spring 2 and a steel ball 3 are arranged in the spring seat 1 and the iron core seat 4, and the spring seat 1 and the iron core seat 4 are provided with sealing inclined planes matched with the steel ball, and refer to fig. 2, namely an upper sealing surface and a lower sealing surface in the drawing. The bottom of the spring seat 1 is provided with an oil inlet hole which is used for being connected with a control oil way of the speed regulator. An oil drain groove is arranged at the side part of the iron core seat and is communicated with the governor oil pool. When the steel ball 3 is not in contact fit with the sealing inclined surface of the spring seat 1 or the iron core seat 4, the speed regulator controls oil to flow in through the oil inlet of the spring seat 1 and then flow out through the oil drain groove of the iron core seat 4, so that the speed regulator controls oil pressure to release, and the power piston moves towards the oil reducing direction, thereby realizing the stop of the diesel engine.
The core holder 4 is provided with a coil 6, a coil bracket 7, a housing 8 and a core 15. The upper half part of the core print seat 4 is positioned in the shell 8, and the shell 8 presses the core print seat 4 and is fixed on the speed regulator through external threads. The iron core 15 is positioned on the iron core seat 4, and the coil 6 is installed in the shell through the coil bracket 7 and surrounds the iron core 15.
The iron core 15 is internally provided with an adjusting rod 16, the adjusting rod 16 is connected with the iron core 15 through threads, the lower part of the adjusting rod is contacted with a push rod 17, the push rod 17 is contacted with the steel ball 3 through a central hole of an iron core seat, and when the iron core 15 moves downwards, the push rod 17 is driven to move downwards, so that the steel ball 3 is pushed to move downwards.
The outside of the iron core 15 is provided with a limit groove, and the limit groove is in clearance fit with the first cylindrical pin 10 which is installed on the shell in an interference manner, so that the rotary motion of the iron core 15 can be limited, and only the up-and-down movement is allowed. When the coil 6 is energized, the iron core 15 inside thereof is influenced by electromagnetic force to move downward.
An iron core blocking plug 12 and a lock nut 11 are arranged above the shell 8, the iron core blocking plug 12 is connected with the shell 8 through threads, and when the iron core blocking plug 12 is well adjusted in position, the lock nut 11 fixes the position of the iron core blocking plug 12. The main function of the iron core stopper 12 is to prevent the iron core 15 from moving upwards, and further limit the upward movement range of the steel ball 3 through the transmission of the adjusting rod 16 and the ejector rod 17.
The first bushing 5 is in interference fit with the iron core seat 4, and the second bushing 13 is in interference fit with the iron core 15, and the two bushings have the function of reducing abrasion of the ejector rod 17 or the iron core 15 in the up-and-down sliding process. The O-shaped sealing ring 14 is positioned in a groove of the adjusting rod 16 and plays roles of increasing friction resistance and reducing the loosening of the matched threads of the adjusting rod 16 and the iron core 15.
The basic working principle of the solenoid valve is based on the magnetic effect of the current, when the coil 6 is energized, the core holder 4 and the core 15 will be magnetized, and since the core holder 4 is restrained and fixed by the housing 8, the core 15 will move in the direction of the core holder 4.
Referring to fig. 3, 4, 5 and 6, the operating principle of the dual mode parking solenoid valve structure to implement the "power on parking" and "power off parking" functions is as follows:
electrifying and parking functions:
the initial position of the associated structure in the dual mode parking solenoid valve when not energized is shown in fig. 3. The steel ball 3 is closely contacted and matched with the sealing surface of the iron core seat 4 under the action of the spring 2, and simultaneously, the ejector rod 17 and the adjusting rod 16 are supported. The adjustment lever 16 is screwed to the iron core 15, and maintains a certain gap h1 between the iron core 15 and the iron core seat 4. The gap h1 is smaller than the movement stroke L of the steel ball 3 from the upper sealing surface to the lower sealing surface, as shown in fig. 2.
When the power is on, the iron core 15 moves downwards until contacting with the iron core seat 4, and then the steel ball 3 is driven to move downwards through the adjusting rod 16 and the ejector rod 17, and the movement stroke is a gap h1. The termination position of the relevant structure is shown in fig. 4.
Because the steel ball 3 is separated from the upper sealing surface after being electrified and is not contacted with the lower sealing surface, the oil can be controlled by the speed regulator to the oil drain groove through the oil inlet, so that the oil pressure is controlled by the speed regulator to be released, the power piston moves towards the oil reducing direction, the stop of the diesel engine is realized, and the function of 'electrifying and stopping' of the stop electromagnetic valve is completed.
The adjusting method comprises the following steps: in the design, the screw-in depth h2 of the adjusting rod 16 inside the iron core 15 can be determined according to the size of each structure, so that the gap h1 is about half of the movement stroke L of the steel ball 3. During adjustment, the adjusting rod 16 is rotated to the depth h2; then the iron core blocking plug 12 is screwed in, a certain gap h3 is kept between the iron core blocking plug and the iron core 15, and finally the iron core blocking plug is locked by the locking nut 11.
Power-off parking function:
the initial position of the associated structure in the dual mode parking solenoid valve after power up is shown in fig. 5. The iron core 15 is tightly contacted and matched with the sealing surface of the spring seat 1 through the adjusting rod 16 and the ejector rod 17 under the action of electromagnetic force, and meanwhile, a certain gap h4 is kept between the iron core 15 and the iron core stop plug 12. The gap h4 is smaller than the movement stroke L of the steel ball 3.
When the power is off, the electromagnetic force disappears, the steel ball 3 moves upwards under the action of the spring 2, and the iron core 15 is pushed to move upwards through the ejector rod 17 and the adjusting rod 16 until the iron core stopper 12 is contacted, and the movement stroke is h4. The termination position of the relevant structure is shown in fig. 6.
Because the steel ball 3 breaks away from the lower sealing surface after power failure and is not contacted with the upper sealing surface, the speed regulator can control oil to the oil drain groove through the oil inlet, so that the speed regulator can control oil pressure to release pressure, further the stop of the diesel engine is realized, and the function of stopping the electromagnetic valve after power failure is finished.
The adjusting method comprises the following steps: when the power is on, the rotary adjusting rod 16 is rotated downwards until the iron core 15 starts to move upwards, and at the moment, the steel ball 3 is in close contact fit with the sealing surface of the spring seat 1; after the power is off, the iron core blocking plug 12 is screwed in, and the rest part of the iron core blocking plug can be slightly higher than the locking nut 11 in design so as to ensure that the gap h4 is about half of the movement stroke L of the steel ball 3, and the iron core blocking plug is locked by the locking nut 11 after being adjusted in place.
