It is sheathed on the coil holder 51, the coil 52, which is powered, generates magnetic field, is attracted described in the magnetic field gravitational attraction that the magnetic field generates
Part 42 is to drive the valve rod 41 to move.
Preferably, installation cavity 511, the one end of the valve rod 41 far from the water inlet 14 are offered on the coil holder 51
It protrudes into the installation cavity 511 and slides and be tightly connected between the inner wall of the installation cavity 511.
The inner wall of the installation cavity 511 is equipped with ring part 512, and the installation cavity 511 is separated shape by the ring part 512
At the first installation cavity 511a and the second installation cavity 511b, looping pit 512a, the looping pit are offered on the ring part 512
512a is connected to the first installation cavity 511a, and the valve rod 41 protrudes into first installation far from one end of the water inlet 14
It is slidably connected in chamber 511a and between the first installation cavity 511a inner wall.
It is connected between coil 52 and the coil holder 51 by bolt arrangement 53, i.e., the described coil 52 passes through the bolt knot
Structure 53 is fixed on the coil holder 51.Certainly, in other embodiments, the coil 52 can also be by removing the bolt
Connection structure other than structure 53 is fixed on the coil holder 51.
Specifically, the bolt arrangement 53 includes bolt 531 and gasket 532, and the coil 52 is equipped with mounting hole 521,
Described 51 one end of coil holder is protruded into the mounting hole 521, and the gasket 532 is resisted against the coil holder 51, then passes through institute
State 531 locking of bolt.
Further, the coil block 50 further includes iron core 54, and the iron core 54 is installed on second installation cavity
In 511b.Preferably, it is interference fitted between the iron core 54 and the inner wall of the second installation cavity 511b, the iron core 54 is close
One end of the looping pit 512a be equipped with sealing element 541, by the sealing element 541 will the second installation cavity 511b with outside
Between seal, the bolt 531 is arranged in the gasket 532 and is threadedly coupled between the iron core 54, thus by described
Cooperation between bolt 531 and the gasket 532 and the iron core 54 realizes that the coil 51 is fixed on the coil holder 52
On.
It is understood that the iron core 54, which is arranged, can increase the magnetic field strength generated after the coil 51 is powered；Its
Secondary, when the coil 51 is powered, when the valve rod 41 being made to move to range, i.e., the described valve port 12 is shown in a fully open operation,
The coil 51 powers off under this state, at this point, the actuation part 42 attracts the iron core 54, the valve port 12 is made to be maintained at opening
State.Further, when the valve rod 41 moves to range, one end that the valve rod 41 is equipped with actuation part 42 leans against institute
It states on sealing element 541, at this point, because of the setting of the ring part 512, so that existing between the actuation part 42 and the iron core 54
Gap, and the gap is set, it can be avoided when incoming fluid between the actuation part 42 and the iron core 54, the actuation part
42 attract too tight and the movement of the valve rod 41 are made Caton phenomenon occur with the iron core 54.
The working principle of the automatic water compensating valve 100 is described below
(1) unlatching of the automatic water compensating valve 100
When the automatic water compensating valve 100 needs to open, the coil 51, which is powered, generates magnetic field, and in the magnetic field in the magnetic field
Power effect is lower to attract the actuation part 42 close to the iron core 54, described even if the valve rod 41 is moved close to the iron core 54
Valve rod 41 drives the lever 31 to move, and the lever 31 drives the movement of seal receptacle 31 to open the valve port 12, described
Water flow is successively flowed out by the valve port 12, valve chamber 11 and non-return structure 141 from the water outlet 14 from the water inlet 13,
Moisturizing is carried out to the system；It is described when the valve rod 41 moves to range, i.e., the described valve port 12 is shown in a fully open operation
Coil 51 powers off, and the actuation part 42 attracts the iron core 54 that the automatic water compensating valve 100 is made to keep full-gear.
(2) closing of the automatic water compensating valve 100
When the automatic water compensating valve 100 needs to close, the coil 51 is reversely powered, to generate and the actuation part
The opposite magnetic field of 42 magnetic force, so that the actuation part 42 and the magnetic field force of generation described in the coil 51 are mutually exclusive, it is described
Valve rod 41 resets, and the lever 31 is driven to reset, so that the reset of seal receptacle 21 be driven to seal the valve port 12.
In the present invention, the automatic water compensating valve 100 is by setting lever assembly 30, thus will be described using lever principle
Valve rod assembly 40 acts on the amplification of the active force on the seal assembly 20, so that the labor-saving opening of the automatic water compensating valve 100
And it is sensitive；Secondly as direction F1 and the seal assembly 20 that the valve rod assembly 40 drives the lever assembly 30 to move
The direction for sealing the directed force F 2 of the valve port 12 is arranged in angle, close so as to reduce the seal assembly 20 as far as possible
The active force for sealing the valve port 12 drives the movement of seal assembly 20 to open the automatic water compensating valve lever assembly 30
The interference of 100 active force, it can understand, drive the movement of seal assembly 20 unlatching described certainly in the lever assembly 30
During dynamic water compensating valve 100, it is only necessary to overcome part or not need that the seal assembly 20 is overcome to seal the valve port 12
Active force can open the automatic water compensating valve 100, further such that the unlatching of the automatic water compensating valve 100 is more laborsaving
And it is sensitive.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
