Description
Technical field
The utility model belongs to art of refrigeration units, particularly a kind of right-angle type valve body 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 right-angle type valve body experimental provision, it is characterized in that: comprise water tank, weighting distribution wheel, rotating shaft, right side wall, compress and admission gear, friction top, upper wall, handwheel, upper hold down gag, holding device, left side wall, undersetting, lower wall; Described water tank is rectangular enclosure body, and there is the groove installing rotating shaft its upper opening both sides; Be placed on ground, water is equipped with in inside; Described weighting distribution wheel is arranged on rotating shaft one end, and configure with rotating shaft bias, center of gravity is relative with valve body mounting portion; Described rotating shaft two ends are arranged in the groove on water tank, and middle part is fixedly connected with lower wall; Described right side wall is arranged on right side, and be template part, its upper end is connected with upper wall, and lower end is connected with lower wall, and centre is provided with compression and steam inlet device installs fixed orifice; Described compression and admission gear are arranged in the middle of right side wall, and in wall, one end is connected with friction top, have contact roller and compressed air interface outside wall; Described friction top is arranged on compression and steam inlet device inner end, contacts with valve body openings; Described upper wall is arranged on the upper end of left side wall and right side wall, and two ends are connected with the upper end of left side wall and right side wall respectively, and middle part is provided with hold down gag; Described handwheel is arranged on hold down gag upper end; Described holding device is arranged in the middle of left side wall, corresponding with the compression of right side wall and steam inlet device; Described left side wall is arranged on left side, and its upper end is connected with upper wall, and lower end is connected with lower wall, and there is holding device mounting hole at middle part; Described undersetting is arranged on Middle face on lower wall, corresponding with upper hold down gag; Described lower wall is arranged on Middle face in rotating shaft, and its two ends are connected with left side wall and right side wall respectively, and there is undersetting mounting hole at middle part.
Beneficial effect
The beneficial effects of the utility model are, can realize carrying out leakage test to right-angle 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
