Abstract
The invention relates to a blind plate central position adjustable device, wherein the top end of a vertically movable blind plate pad is provided with a vertically movable driving oil cylinder, the right end of a horizontally movable blind plate pad is provided with a horizontally movable driving oil cylinder; the vertically movable blind plate pad and the horizontally movable blind plate pad areprovided with a vertical movement guiding device and a horizontal movement guiding device respectively; and the lower end of the vertically movable blind plate pad is provided with a weight balancing oil cylinder of a blind plate system. A fixed mounting type single blind plate is changed into the horizontally movable blind plate pad which can be moved and adjusted in the horizontal direction and a vertically movable blind plate pad which can be moved and adjusted in the vertical direction, the weight balancing oil cylinder of a blind plate pad system is arranged below the blind plate pads, a nd the randomly adjustable jacking force of the weight balancing oil cylinder holds up the blind plate pad system, so that the blind plate pad system is in a floating state and is driven by the horizontally movable driving oil cylinder and the vertically movable driving oil cylinder respectively, thus the blind plate pad system can be adjusted randomly in the vertical and horizontal directions andthe blind plate can get into a passage of a valve conveniently.
Description
Technical field
The present invention relates to a kind of internal expansion type seal form and carry out blind plate (plug) in the valve detection device, the regulating device of especially a kind of blind plate (plug).
Background technology
At present, when adopting the internal expansion type seal form to carry out valve detection, because there is certain nonconcentricity in the passway at valve two ends, there is very big nonconcentricity in the welded type valve that adds sleeve especially, and blind plate (plug) be fixedly mounted on valve test bed on, blind plate (plug) is difficult to even the passage that can't enter valve seals, so that can't carry out the test of valve.
Summary of the invention
The present invention will provide a kind of blind plate center adjustable apparatus, and this device can make blind plate (plug) enter the passage of valve very easily.
For achieving the above object, technical scheme of the present invention is: a kind of blind plate center adjustable apparatus, comprise the blind plate pad, and be characterized in: the blind plate pad is divided into vertical moving blind plate pad and moves horizontally the blind plate pad, and goes to upper and lower layer layout; Vertical moving blind plate pad top is provided with vertical moving and drives oil cylinder, moves horizontally blind plate pad right-hand member and is provided with and moves horizontally the driving oil cylinder; Vertical moving blind plate pad is respectively equipped with the vertical moving guide piece and moves horizontally guide piece with moving horizontally above the blind plate pad; Vertical moving blind plate pad lower end is provided with blank plate system weight balancing oil cylinder.
Move horizontally drive oil cylinder by swing arm with move horizontally the blind plate pad and be connected; Move horizontally drive oil cylinder and vertical moving drive oil cylinder respectively the three position four-way electromagnetic valve by separately be connected with fluid clutch; Blank plate system weight balancing oil cylinder is connected with fluid clutch by pressure regulator valve; The hydraulic-driven pump output terminal also is connected to surplus valve and blowdown valve; Be provided with reservoir between blank plate system weight balancing oil cylinder and the pressure regulator valve.
The invention has the beneficial effects as follows:
The present invention with the monolithic backing plate of former fixed installation pattern make into for can move in the horizontal direction adjust move horizontally blind plate pad (lower floor), with the vertical moving blind plate pad (upper strata) that can move adjustment in vertical direction, below the blind plate pad, be provided with a blind plate (pad) system weight balancing cylinder, this oil cylinder can arbitrarily be adjusted, the top power of setting up, upwards hold blind plate (pad) system, make blind plate (pad) system be in a kind of unsteady state, drive respectively by moving horizontally driving oil cylinder and vertical moving driving oil cylinder again, can make blind plate (pad) system regulated at will on vertical and horizontal direction, make blind plate (plug) enter the passage of valve very easily.
