Description
Technical field
The utility model belongs to art of refrigeration units, particularly a kind of multiple through way valve experimental provision.
Background technology
Ammonia valve, it is a kind of assembly conventional in refrigeration plant, its effect is that conventional ammonia valve comprises valve body mostly, import in refrigeration systems to the flowing or the blocking-up that control cold-producing medium in the use procedure of cold-producing medium by closing and open ammonia valve, import joint flange, outlet, outlet joint flange, flap, handle, end cap; Import joint flange is connected with the input channel of cold-producing medium, cold-producing medium enters ammonia valve by input channel, by the gap of flap and outlet, enter outlet, outlet joint flange is connected with cold-producing medium output channel, cold-producing medium enters output channel after ammonia valve, completes conveying or the circulation of normal cold-producing medium; When needs block conveying or circulation, turn handle, make to close between flap and outlet, cold-producing medium is just blocked by flap and can not export from outlet; And when valve blocks cold-producing medium, do not allowed leakage; In the production run of ammonia valve, due to valve body be often in the high pressure conditions of cold-producing medium under work, and cold-producing medium has stronger volatility, the sealing of valve body itself is very important, after valve body has been produced, generally all need to seal and strength test valve body, existing method adopts flange to seal the import and export of valve body, then pressurizeed by a port, to check sealing and the intensity of valve body, this method, need repeatedly to dismantle seal flange, pressurization, inefficiency, labour intensity is large.
Summary of the invention
For Problems existing in existing ammonia valve valve body process of the test, the utility model proposes a kind of multiple through way valve experimental provision, it is characterized in that: comprise experimental provision, liquid input tube road, hydraulic system; Described experimental provision has multiple, and parallel connection is emitted on together, comprises, hydraulic jack, frame, by-pass valve control, top cover under valve body, valve body upper top cover; It is vertical with end face in frame that described hydraulic jack is fixedly mounted on frame top; Described frame comprises column, upper end face, intermediate plate, base; Described column is positioned on base, is fixedly connected with respectively with intermediate plate with upper end face; Described upper end face is fixedly mounted on its plane of top and uprights vertical on column, and there is hydraulic jack mounting hole in its centre; Described intermediate plate to be arranged in the middle part of column and between multiple column, intermediate plate is provided with the installation and fixed orifice of installing top cover under valve body; Described floor installation on the ground, is fixedly connected with column above it; Described by-pass valve control is arranged on liquid input tube road, corresponding each experimental provision one; Under described valve body, top cover is arranged on intermediate plate, and its upper end is provided with seal element and liquid inlet; Described valve body upper top cover is arranged on the piston rod end of hydraulic jack, is provided with seal element; Described liquid input tube road is arranged in frame, and is connected with multiple experimental provision; Described hydraulic system is arranged on one side of experimental provision, controls the mode of motion of each hydraulic cylinder.
Beneficial effect
The beneficial effects of the utility model are, can realize carrying out leakage test to through type valve body fast, and reduce labour intensity, work efficiency is high, reduce operating personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
1. hydraulic jack, 2. frame, 3. by-pass valve control, 4. liquid input tube road, 5. top cover under valve body, 6. valve body upper top cover.
Embodiment
In order to further illustrate the technical solution of the utility model, now further illustrate embodiment of the present utility model by reference to the accompanying drawings, as Fig. 1, select wide 40 millimeters, the rectangular steel pipe of long 60 millimeters, as the column of frame 2, highly 1500 millimeters, selects the quantity of column to be 4 in this example; Same rectangular steel pipe is selected the lower end firm welding of 4 columns to be formed 400 mm wides, the rectangle of 500 millimeters long as the base of frame 2; Select thickness 12 millimeters, long 500 millimeters, the steel plate of wide 400 millimeters, as the intermediate plate of frame 2, processes installation and the fixed orifice of top cover 5 under valve body in the middle; Select thickness 12 millimeters, long 500 millimeters, the steel plate of wide 400 millimeters as the upper end face of frame 2, and processes installation and the fixed orifice of hydraulic jack 1 in the middle, intermediate plate is welded on 600 millimeters, height distance ground place between 4 columns, upper end face is welded on the upper top of 4 columns; Above step produces frame 2; 5 experimental provisions are selected to be one group in this example; Hydraulic jack 1 is arranged on respectively the upper end face of frame 2, and is connected with hydraulic system; Valve body upper top cover 6 with O-ring seal is arranged on the piston rod end of hydraulic jack 1; Be fixedly mounted on intermediate plate by top cover under valve body 5, its sealing surface is towards the direction of hydraulic jack 1; And adopt pipeline to be connected with by-pass valve control 3 liquid inlet; Select the steel pipe of diameter 35 millimeters as liquid input tube road 4, closed its one end, the other end is connected with liquid source of supply, and reserves valve 3 installation site in the corresponding position of each experimental provision, and by-pass valve control 3 is installed on it, and entirety is fixedly connected with frame 2; Just complete enforcement of the present utility model; During application, to control the through type ammonia valve valve body of mouth good seal, one end contacts with top cover under valve body 5, and the other end is towards valve body upper top cover 6, primer fluid pressing system, the piston rod movement band moving valve upper top cover 6 of hydraulic jack 1 moves downward and the compression suitable for reading of ammonia valve valve body is sealed; Opening controlling valve door 3, highly pressurised liquid enters in ammonia valve valve body by top cover 5 under by-pass valve control 3 and valve body, keeps a period of time, observes whether have leakage; After having tested, closing control valve 3, primer fluid pressing system makes hydraulic jack 1 counter motion, unclamps ammonia valve valve body, just completes a working cycle; Owing to there being multiple experimental provision, operating personnel's periodic duty can being realized, improve work efficiency, decrease operating personnel, simultaneously owing to not needing repeatedly to install and remove seal flange, reduce labour intensity.
