Description
Technical field
The utility model relates to a kind of selector valve, particularly relates to a kind of electromagnetic assembled selector valve.
Background technique
In hydraulic control system, solenoid valve, selector valve are conventional valve elements, for oil-feed and the oil return of oil circuit control, complete certain control action by the cooperation of oil cylinder and executive component again, such as, in the medical equipment such as the medichair in medical equipment apparatus and small lifting table, the upper and lower elevating movement controlling a group oil cylinder obtains four oil cylinders, the oil cylinder quantity of whole system is many, complex structure, bulky, inconvenient maintenance; Occur that oil cylinder quantity is mainly with rear, leak many comparatively speaking, easily cause misoperation, have influence on the safety reliability of equipment running.Can adopt a kind of small-sized Combined electromagnetic valve group with multiple action request of the Informal development of combination, be one of problem of hydraulic element production unit research in recent years.
Summary of the invention
The purpose of this utility model to provide the compact electromagnetic combined directional valve that a kind of structure is simple, level of integration is high, safe and reliable, to meet the requirement of medical device miniaturization.
Electromagnetic assembled selector valve of the present utility model can adopt following technological scheme to implement: it comprises filter screen and check valve assembly, three-position four-way electromagnetic directional valve, bi-bit bi-pass cut-off type solenoid directional control valve and manifold block assembly, wherein three-position four-way electromagnetic directional valve is screwed on manifold block assembly by filter screen and check valve assembly, its junction plane is equipped with the O RunddichtringO made by fluorine silica gel material, bi-bit bi-pass cut-off type solenoid directional control valve is fixed in the patchhole of bi-bit bi-pass cut-off type solenoid directional control valve corresponding on manifold block assembly by wresting-in type structure.The quantity of bi-bit bi-pass cut-off type solenoid directional control valve requires to determine according to user, can increase arbitrarily.
Compared with prior art, its outstanding advantage is the electromagnetic assembled selector valve designed and produced according to technique scheme:
1, oil-feed is by one piece of filter screen, to ensure the turbidity test of oil circuit, prevents from blocking.
2, the oil-feed of two groups of bi-bit bi-pass cut-off type solenoid directional control valves and the switching action of oil return is distributed by three-position four-way electromagnetic directional valve, make the bi-bit bi-pass cut-off type solenoid directional control valve controlling two-way cylinder reduce to two from original four, make whole valve group volume reduce nearly half.
3, manifold block assembly, solenoid valve all adopt the Sealing that fluorine silica gel material is made, durable in use, improve the working life of solenoid valve.
4, the cone valve of bi-bit bi-pass cut-off type solenoid directional control valve and valve seat adopt soft and hard seal technology, make internal leakage less, almost close to zero leakage, make system more safe and reliable.Bi-bit bi-pass cut-off type solenoid directional control valve mounting type adopts wresting-in type structure, dismantles convenient.
5, all hydraulic fluid ports on electromagnetic assembled selector valve all adopt and are threaded, and user installation is easy to maintenance.

Embodiment
Below in conjunction with drawings and Examples, electromagnetic assembled selector valve of the present utility model is further described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4: electromagnetic assembled selector valve comprises: filter screen and check valve assembly 1, three-position four-way electromagnetic directional valve 2, bi-bit bi-pass cut-off type solenoid directional control valve 3 and manifold block assembly 4, wherein three-position four-way electromagnetic directional valve 2 is screwed on manifold block assembly 4 by filter screen and check valve assembly 1, its junction plane is equipped with the O RunddichtringO made by fluorine silica gel material, and bi-bit bi-pass cut-off type solenoid directional control valve 3 is fixed in the patchhole of bi-bit bi-pass cut-off type solenoid directional control valve corresponding on manifold block assembly 4 by wresting-in type structure.The quantity 3n of bi-bit bi-pass cut-off type solenoid directional control valve requires to determine according to user, can increase arbitrarily.(diagram 3n=6, namely 31,32....38), after certainly increasing, corresponding manifold block assembly must be changed or expand).
During the electromagnetic assembled selector valve work made according to said structure as shown in Figure 5: as oil enters from P mouth, during by three-position four-way electromagnetic directional valve, when a works, P-P1 conducting, P2-T conducting, as electromagnet B works, oil cylinder 31 rises (B is one-way cylinder), when oil cylinder 32,33 works simultaneously, and A oil return, E oil-feed, A-P2 conducting, P2-T conducting then A-T conducting, when oil cylinder 33 works, P1-E conducting, oil cylinder E oil-feed, all the other the like.When b switches, when oil cylinder 31 works, oil cylinder declines under gravity, P-P2 conducting, P1-T conducting; When oil cylinder 32,33 works simultaneously, 33 oil returns, then oil cylinder A oil-feed, oil cylinder moves upward, all the other the like.P described above is filler opening, T is return opening, and A, B, C, D, E, F, G, H are working hole.
