Piston still easily brings the impurity in the external world or dirt into electromagnetic unit inner chamber in upper and lower motion, so as to cause it to cause dirt
Dye and then generation mechanism failure, even damage, and then influence the various aspects of performance of valve.
The structure of specific existing valve electromagnetic unit, reference can be made to the Application No. of the applicant's earlier application
" 201520618955.3 ", the electromagnetic unit disclosed in entitled " a kind of electromagnetism feed water valve ".
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of electromagnetic unit of valve.
It is an object of the present invention to provide a kind of electromagnetic unit of valve, to prevent piston external world in upper and lower motion
The drawbacks of magazine is easily accessible inside electromagnetic unit, the electromagnetic unit include housing, the coil block being arranged in housing, determined
Iron core, dynamic iron core, piston and the elastic component being arranged between the fixed core and the dynamic iron core, the piston are fixed on described
Dynamic iron core, the dynamic iron core move axially under coil block electromagnetic force along it, are set on the mobile route of the piston
Put a seal to be sealed, the seal has two lips, forms opening between two lips, described opening down to set
Put.
In above-mentioned technical proposal, the seal is Y types seal or C-seal.
In above-mentioned technical proposal, the lower end of the dynamic iron core is provided with fixing hole, the piston upper end form with it is described
The fixed column that fixing hole coordinates.The position that said structure avoids piston and may occurred relative to dynamic iron core is offset.
In above-mentioned technical proposal, the housing includes the piston seat that lower section is set, formed with layer hole in the piston seat,
The seal, piston guide block and a retaining back-up ring are set gradually in the layer hole.
In above-mentioned technical proposal, it is encapsulated that sealing is provided with the bottom of the piston.
In above-mentioned technical proposal, the piston seat is detachably fixed with the housing and is connected.
The utility model has the advantages that：The utility model has the seal of two lips by setting, thus
So that when piston is in upper and lower motion, extraneous impurity or dirt are difficult to be brought into electromagnetic unit inner chamber, and then cause electromagnetism list
The life-span of member greatly improves.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model electromagnetic unit.
Fig. 2 is the partial enlarged drawing in Fig. 1.
Fig. 3 is the structural representation of the isolated pressure-stabilizing constant flow valve of the utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1 to Fig. 2,
A kind of electromagnetic unit of valve, including housing 1, the coil block 2 being arranged in housing 1, fixed core 3, dynamic iron core 4, piston 5 and set
The elastic component 100 between the fixed core 3 and the dynamic iron core 4 is put, the piston is fixed on the dynamic iron core 4, described dynamic
Iron core 4 moves axially under the electromagnetic force of coil block 2 along it.
Wherein, a seal 6 is set to be sealed on the mobile route along the piston 5, the seal 6 has
Two lips 60, opening 61 is formed between two lips 60, described opening 61 is set down.
As specific two kinds of forms of seal 6, the seal 6 can be Y types seal or C type seals.
Preferably, the lower end of the dynamic iron core 4 is provided with fixing hole 40, and the upper end of piston 5 forms and the fixation
The fixed column 50 that hole 40 coordinates.By the way that fixed column 50 is set in fixing hole 40 to realize that the fastening of piston 5 and dynamic iron core is matched somebody with somebody
Close, the position that said structure avoids piston 5 and may occurred relative to dynamic iron core 4 is offset.
The housing 1 includes the piston seat 10 that lower section is set, formed with layer hole 10a in the piston seat 10, described
The seal 6, the retaining back-up ring 8 of piston guide block 7 and one are set gradually in layer hole 10a.The seal 6 is pressed in institute
State between layer bottom hole wall and the piston guide block 7, the retaining back-up ring 8 is used to prevent the piston guide block 7 in axial position
The sliding put.The piston guide block 7 can use wear-resisting, the corrosion resistant material of nylon plastic(s) energy, whole to increase electromagnetic unit
The service life of body.
Sealing encapsulated 9 is provided with the bottom of the piston 5, for enter at valve pocket that the piston and its coordinate
Row sealing.The piston seat 10 is detachably fixed with the housing 1 and is connected, and is easy to the installation and maintenance of electromagnetic unit.
Referring to Fig. 3, the isolated pressure-stabilizing constant flow valve with electromagnetic unit in the application, including valve body 90 are shown in Fig. 3
