Abstract
The utility model belongs to the technical field of mechanical equipment, and relates to a hydraulic-drive pressure testing tool of a valve. Included are the pressure testing tool and a control cabinet which are connected by two pressure testing pipelines. The tool comprises a hydraulic cylinder cover, a hydraulic cylinder, a piston post, a spring, a connecting plate, a pressure testing upper blind plate, a pressure testing lower blind plate, a baffle plate, screws, bolts, and nuts. The bolts and the nuts penetrate through the hydraulic cylinder cover and the baffle plate and then are screwed up to fix the hydraulic cylinder cover and the baffle plate into a whole. The hydraulic cylinder cover is fixed with the hydraulic cylinder through a locking screw and then sealed by an O-shaped sealing ring. The piston post is arranged inside the hydraulic cylinder and sealed with the inner wall of the hydraulic cylinder by the O-shaped sealing ring. The lower part of the hydraulic cylinder is provided with the spring used for return of the piston post. The lower part of the piston post and the connecting plate and the pressure testing upper blind plate are fixed with into a whole by a connecting screw. The baffle plate is provided with the pressure testing upper blind plate, and the center position of the baffle plate is identical to that of the pressure testing upper blind plate. The baffle plate is also provided with a standard pressure testing sealed backing ring. The hydraulic-drive pressure testing tool of the utility model is simple in structure and rapid and practical in usage. The pressure charging is conducted through automation operations and is convenient and safe. The pressure testing time is shortened, and the working efficiency is increased.
Description
Technical field
The utility model belongs to mechanical equipment technical field, hydraulic operated fixture device that be specifically related to connect for various gasket rings, low pressure valve sealing and strength test, the i.e. structure for pressure test that surges of valve.
Background technology
At present, known valve all will carry out intensity and experiments of sealing performance according to national standard or international standard before dispatching from the factory, and is all to use gasket ring or O-ring seal sealing, all to carry out the hand assembled test, lose time, lower efficiency, and manually easily the sealing surface of workpiece is damaged during the pressure testing pretension.Under this background, need especially a kind of valve structure for pressure test that surges that can be quick and safe.
Summary of the invention
The purpose of this utility model is: a kind of structure for pressure test that surges of valve is provided, and simple in structure, install and remove easy to connectly, can meet various model value pressure tests; Improve the work efficiency of assembling pressure testing.
Main technical schemes of the present utility model: the structure for pressure test that surges of valve, comprise structure for pressure test and switch board, frock is connected with switch board by two pressure testing pipelines, it is characterized in that frock comprises in fluid cylinder lid, fluid cylinder, piston boit, spring, web joint, pressure testing blind plate, baffle plate, screw, bolt and nut under blind plate, pressure testing; Screw bolt and nut screws and is fixed as integral body through fluid cylinder lid and baffle plate; The fluid cylinder lid is fixed by lock-screw and fluid cylinder and is passed through the sealing of " O " RunddichtringO, and piston boit is located at fluid cylinder inside, by the inner wall sealing of " O " RunddichtringO and fluid cylinder; The fluid cylinder bottom is provided with the spring for the piston boit return, and piston boit bottom and web joint are fixed as one by blind plate in attachment screw and pressure testing; Establish blind plate under pressure testing on baffle plate, center is consistent with blind plate in pressure testing, and is furnished with the pressure testing gasket ring of standard; Switch board connects fluid cylinder by a pressure testing pipeline, by an other pressure testing pipeline, connects the pressure testing valve cavity.
Usually, the utility model frock comprises six roots of sensation bolt and 12 nuts.
During the utility model work, determined the structure length of valve by the effective travel of piston, during pressure testing pipeline entrance pressure, promote piston boit and move right to withstand valve, enter test pressure by an other pressure testing pipeline, by the gasket ring on the upper and lower blind plate of pressure testing, guarantee the both sides sealing simultaneously.After pressure testing finishes, the first pressure release of switch board Control experiment pressure medium, then control the hydraulic pressure pressure release, and the tension force of spring promotes piston boit and resets.In pressure testing under blind plate and pressure testing blind plate and gasket ring can change according to the type of attachment of valve end, to meet the pressure testing of various model valves.
Frock of the present utility model is controlled hydraulic pressure by switch board, enters fluid cylinder promotion piston boit through pressure line and withstands the valve both sides, neither can squeeze the gasket ring sealing surface of bad valve, also guarantees the acting force of pressure testing sealing simultaneously.Control an other pressure line by switch board again, test(ing) medium arrives valve cavity through this pressure line, and the valve both sides rely on the standard seal gasket ring and sealed pressure testing.When opening, valve plate can also make a strength test.
The utility model is simple in structure, Fast Practical, and the automatic operation entrance pressure, convenient and safe, reduce the pressure testing time, increase work efficiency.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment frock.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.
Embodiment: valve surge the structure for pressure test structure as shown in accompanying drawing 1, comprise structure for pressure test and switch board, frock is connected with switch board by two pressure testing pipelines, and this structure for pressure test mainly comprises: fluid cylinder covers 1, blind plate 14, baffle plate 15, nut 16 and bolt 17 under blind plate 10, gasket ring 11, gib screw 13, pressure testing on lock-screw 2, " O " O-ring seal 3, piston boit 4, spring 5, fluid cylinder 6, bearing sliding bush 7, attachment screw 8, web joint 9, pressure testing.
Switch board arranges respectively two pressure lines, is respectively pressure line I 18 and pressure line II 19.In one bar access fluid cylinder, for the fixation pressure that surges is provided, another is for providing test(ing) medium pressure.During work, determined the structure length of valve by the effective travel of piston, during pressure line 1 entrance pressure, promote piston boit and move right to withstand valve 12, then enter test pressure by the pressure line II, by the gasket ring on the upper and lower blind plate of pressure testing, guarantee the both sides sealing.After pressure testing finishes, the first pressure release of switch board Control experiment pressure medium, then control the hydraulic pressure pressure release, and the tension force of spring promotes piston boit and resets.In pressure testing under blind plate and pressure testing blind plate and gasket ring can change according to the type of attachment of valve end, to meet the pressure testing of various model valves.
