Description
Technical field
The utility model relates to a kind of equipment extracting tool, relate in particular to a kind of can dismantle the different size hydraulic valve get the valve device.
Background technology
At present, hydraulic technique has been penetrated into every field, and is especially very extensive in the auto industry field utilization, and develops into a complete automatic technology that comprises transmission, control and detection.Hydraulic valve is in design and installation process, in order to prevent to let out in it and damage at work, its installation accuracy and fit clearance require all very high, and the hydraulic valve outer wall cooperates very tight with the valve piece, and do not have utilizable stress point on the valve piece, so the dismounting hydraulic valve is very difficult.At present, when hydraulic valve overhauls, usually just employing is colluded tool easily and is caught on the valve piece, with its taking-up, and owing to do not have utilizable stress point on the valve piece, therefore, not only very inconvenient with colluding tool dismounting hydraulic valve, be not easy to take out the valve piece, but also abnormally dangerous, be very easy in disassembly process, hydraulic valve is caused nonvolatil damage.Though, had company to get the valve device, but had a lot of problems what design was applicable to hydraulic valve.
Chinese patent publication number CN201257649Y, the patent application case in open day on June 17th, 2009 discloses a kind of provision for disengagement of hydraulic valve block plug-in mounting check valve, and it is formed and is connected by following parts: be with open type screw rod cover on screw rod; The bottom of screw rod is a truncated cone-shaped; Gland is equipped with on top at the screw rod cover, and the nut next-door neighbour of being equipped with on screw rod connects gland; Be positioned over the support set between plug-in mounting check valve and the gland during use.The provision for disengagement of the hydraulic valve block plug-in mounting check valve of this scheme by turning nut, is expanded open type screwed pipe cover, and is fixed on the inwall of valve piece, and outwards the valve piece is taken out in pulling, thus the dismounting hydraulic valve.Mainly there is following problems in this scheme:
1. need turn nut, open type screwed pipe cover is expanded, not only operation is not too convenient, and the open type screwed pipe be enclosed within repeatedly use after reliability can descend, need to change;
2. open type screw rod cover contacts with face with hydraulic valve employing face and fixes, and is not easy to clamp, and skids easily, causes the dismounting failure, even hydraulic valve is sustained damage;
3. versatility is relatively poor, can only adapt to the hydraulic valve of interior specification very among a small circle.
The utility model content
The purpose of this utility model is to solve in the prior art, hydraulic valve is when keeping in repair or maintain operation, dismounting hydraulic valve inconvenience, the problem of damage hydraulic valve provides a kind of and can dismantle hydraulic valve simply, easily easily, can not damage hydraulic valve and hydraulic test, versatility is good, adapt to the different size hydraulic valve, and cheap for manufacturing cost, and the novel universal of long service life is got the valve device.
In order to solve the problems of the technologies described above, the utility model adopts following technical proposals:
A kind of general valve device of getting comprises and gets valve head and handle, also comprises mandrel, the mandrel front end with get valve head and removably connect, get valve head and be provided with and get the valve clamp, core back-end connects handle, mandrel is outside equipped with ejector, and ejector and mandrel are slidingly connected, and ejector armrest handle one end is provided with handle.Major programme of the present utility model provides a kind of valve device of getting, it comprises that is got a valve head, get valve head be used to stretch into hydraulic valve and utilize on it be provided with get the valve clamp, clamp the valve piece of hydraulic valve easily, ejector is used to control the folding of getting the valve clamp, handle is used for gripping gets the valve device, handle is used for cooperating with handle the control ejector, the front end of mandrel connects gets valve head, and it is detachable to get valve head, be convenient for changing the valve head of getting of different size, increased the scope of application of getting the valve device, strengthened the versatility of getting the valve device.Ejector slides outside mandrel, and the ejector front end is unclamped or push down and get the valve clamp, the folding that the valve clamp is got in control, the valve device discharges or the valve piece of clamping hydraulic valve thereby control is got.The general valve device of getting of the present utility model holds hydraulic valve with one, and another holds the handle of getting the valve device, and use the finger manipulation handle, the control ejector slides outside mandrel to the back-end, thus control get the valve clamp and unclamp, will get valve head and stretch into hydraulic valve, operating handle again, control ejector forward end is slided, and chucking is got the valve clamp, gets valve head the valve piece of hydraulic valve is clamped tightly, to get the valve device again and pull out outward, just hydraulic valve can be dismantled easily together with the valve piece.The general valve device of getting of the present utility model is got hydraulic valve convenience, safety, can not damage hydraulic valve, and is simple in structure, low cost of manufacture, long service life, and get valve head and can dismantle, be convenient for changing the valve head of getting of different size, be applicable to the hydraulic valve of different size, highly versatile.
As a kind of preferred version, the described valve head of getting is cylindrical, get the valve head front end and be provided with hemispheric guide head, guide head with get valve head junction slyness, the center, rear end of getting valve head is provided with columniform thread groove, gets valve head and is connected with mandrel thread by thread groove, and the left and right sides of thread groove is provided with the clamp groove of rectangle, clamp groove both sides are the clamp cell wall, and each is got that the valve clamp is separately positioned in the clamp groove and be hinged with the clamp cell wall.The valve piece center of hydraulic valve is normally cylindrical, therefore get valve head also for cylindrical, the hemispheric guide head of getting the valve head front end plays guide effect, guide head with get valve head junction slyness, guide head makes the valve device of getting of the present utility model use more convenient and safety, in the time will getting the valve device and put in hydraulic valve, hemispheric guide head is as safe as a house in the process of advancing, the hydraulic valve inwall that is not easy to damage, thus guide the whole valve head of getting to put in hydraulic valve inside, take out the valve piece of hydraulic valve.The thread groove of getting the valve head rear end is used to connect mandrel, gets valve head and is connected with mandrel thread, thereby can change the valve head of getting of different size easily.Get the valve clamp and be arranged in the clamp groove, hinged with the clamp cell wall.Propeller slides to the back-end, gets the valve clamp and unclamps, and can be folding to the guide head rear end, and the propeller forward end is slided, and gets the valve clamp and turns to and get the valve head both sides and form projection, gets valve clamp chucking valve piece inwall.This is simple and reliable for structure, and with getting valve clamp chucking valve piece inwall, is not easy to skid, and clamping is more reliable and more stable, can not cause the dismounting failure because of dismantling landing midway, and good reliability can not damaged hydraulic valve.
