Description
[technical field]
The utility model relates to permanent magnetic valve, relates in particular to a kind of permanent magnetic valve with one-piece piston.
[background technique]
Permanent magnetic valve is meant that it utilizes the energy of fluid itself with the valve of permanent magnet control, uses differential pressure control method, come release bolt in the actuating valve by the magnetic force coupling by the outer permanent magnet of movement of valve, thereby the logical of control valve closes.How traditional relatively valve is controlled with bar, axle, and permanent magnetic valve does not have inserts, do not have dynamic seal, has realized the zero leakage of valve, and is convenient for installation and maintenance, low cost of manufacture, long service life.
In traditional permanent magnetic valve, its piston is common assembly parts, is promptly connected to form by release bolt and release bolt nut by upper piston and lower piston, and Sealing is installed on the piston by the impacting force of release bolt nut.When the pistons work pressure-bearing, release bolt screw will bear the pulling force much larger than its intensity, thereby causes release bolt lengthening deformation.In addition, therefore Sealing also can become flexible the sealing that influences permanent magnetic valve, even the situation of release bolt screw occurs breaking.In addition, the piston of this structure is because the inner not sealing of release bolt, and hydraulic pressure enters Sealing inside, and Sealing is strutted, and causes Sealing loosening even come off.
[model utility content]
In view of this, the utility model provides a kind of permanent magnetic valve with one-piece piston that overcomes the problems referred to above.
A kind of permanent magnetic valve with one-piece piston, comprise Handleset, mangetic core assembly, piston assembly, valve gap and valve seat, described Handleset is arranged on described valve gap top and is connected with it, described mangetic core assembly is arranged in the described valve gap, described piston assembly is arranged in the described valve seat and with described mangetic core assembly and is connected, and described valve gap and described valve seat mutually combine.Described piston assembly comprises all-in-one-piece piston main body and seal ring, and described seal ring is set on the described piston main body.
Preferably, described seal ring is an O-ring seals.
Preferably, the lower end of described valve gap has trapezoidal internal thread, and the upper end of described valve seat has the trapezoidal outside thread that is complementary with described trapezoidal internal thread.
Preferably, described permanent magnetic valve also comprises the permanent-magnet component that is fixed in the described Handleset, and described mangetic core assembly can be controlled described piston assembly motion under the magneto drive of described permanent-magnet component.
Permanent magnetic valve with one-piece piston of the present utility model bears the pressure of piston assembly when working by adopting all-in-one-piece piston main body, make piston assembly can show better compression resistance and can reduce the influence of hydraulic pressure, thereby can improve the performance and the working life of permanent magnetic valve seal ring.
[description of drawings]
Fig. 1 has the cross section structure schematic representation of the permanent magnetism angle valve valve of one-piece piston for first preferred embodiment of the present utility model.
Fig. 2 has the cross section structure schematic representation of the straight valve of permanent magnetism of one-piece piston for second preferred embodiment of the present utility model.
[embodiment]
In order to understand the utility model better, be described in detail below with reference to instantiation and accompanying drawing mode of execution to model utility.
For addressing the above problem, the utility model provides a kind of permanent magnetic valve with one-piece piston.As shown in Fig. 1 and Fig. 2, it is respectively the cross section structure schematic representation of first, second preferred embodiment of the present utility model.Wherein, be schematic cross-section shown in Fig. 1 with permanent magnetism angle valve of one-piece piston, Figure 2 shows that the schematic cross-section of the straight valve of permanent magnetism with integrated type forwarder.The permanent magnetism angle valve is similar to the straight valve arrangement of permanent magnetism, forms by component such as Handleset 10, permanent-magnet component 20, mangetic core assembly 30, piston assembly 40, valve gap 50, valve seats 60.
Permanent-magnet component 20 can be annular permanent magnet, and it is installed in the lower handle 14 formed annular grooves (not indicating) of Handleset 10, and can be along with Handleset 10 together moves after 12,14 engagings of lower handle on the Handleset 10.
Piston assembly 40 is arranged in the valve seat 60 and with mangetic core assembly 30 and is connected, and can together move with mangetic core assembly 30.Piston assembly 40 comprises one-piece piston main body 42 and is enclosed within the O-ring seals 44 of piston main body 42 bottoms.Seal ring 44 can adopt standard piece O-ring seals rather than dedicated sealing member, install simpler, cost of material is lower.
The part that extends upward of valve gap 50 extends in the Handleset 10 and is attached thereto.The lower end of valve gap 50 has trapezoidal internal thread (indicate), and is threaded between the trapezoidal outside thread (indicating) of the upper end of valve seat 60.
Above-mentioned permanent magnetic valve utilizes the hydraulic pressuring difference control principle, changes according to the upper and lower pressure reduction of piston assembly 40 and controls the opening and closing that permanent magnetism drives permanent magnetic valve.Drive permanent-magnet component 20 by operating grip assembly 10, the magneto drive of 20 pairs of mangetic core assemblies 30 of permanent-magnet component realizes the control to piston assembly 40 upper and lower pressure reduction variations, thereby controls the switch of permanent magnetic valve indirectly.Therefore, the switch of operating grip assembly 10 may command permanent magnetic valves.
In above-mentioned permanent magnetic valve with one-piece piston assembly 40, hydraulic pressure is born by piston main body 42 fully, seal ring 44 only is used for valve seal and does not bear hydraulic pressure, one-piece piston main body 42 can overcome the adverse effect of hydraulic pressure to piston main body 42 and seal ring 44, performance and the working life that can improve permanent magnetic valve fully.On the other hand, on production technology, the making of one-piece piston assembly 40 is simpler, size is cooperated not have be strict with, and also can save several roads assembly process during assembling, saves production cost and enhances productivity.
The above embodiment has only expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
