Description
Technical field
The utility model relates to mechanical engineering valve technology field, particularly relates to a kind of top-loading ball valve tool structure.
Background technique
Valve is in fluid system, is used for controlling the device of the direction of fluid, pressure, flow.Valve is the device medium in pipe arrangement and equipment (liquid, gas, powder) being flowed or stops also controlling its flow.
Valve is controlling component in pipeline fluid transporting system, and it is used to change path section and media flow direction, has the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.For the valve that fluid controls, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification various, the inside nominal diameter of valve reaches greatly the industrial pipeline valve of 10m to latus rectum from atomic little Gauge Valves.Valve can be used for controlling all kinds such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid and fluidly flows, the working pressure of valve can ultrahigh pressure from 0.0013MPa to 1000MPa, and operating temperature is from the ultralow temperature of-270 DEG C to the high temperature of 1430 DEG C.The control of valve can adopt the multiple kind of drive, as manual, electronic, surge, pneumatic, turbine, electromagnetic driven, electromagnetism surge, electricity surges, air-or liquid-operated, spur wheel, umbrella gear driving etc.; Can under the effect of pressure, temperature or other form transducing signal, by predetermined requirement action, or do not rely on transducing signal and simply open or close, valve rely on drive or automechanism makes open-shut device be elevated, slippage, swing or rotation motion, thus the size changing its Flow area is to realize its controlling functions.
Along with the development of society, use top-loading ball valve is had in fields such as chemical industry, petrochemical industry, oil, papermaking, mining, electric power, liquid gas, food, pharmacy, plumbing, municipal administration, mechanical equipment coordination, electronics industry, urban construction, top-loading ball valve valve body is integrated, spheroid and valve rod are connected, and therefrom flange loads; Valve seat, seal ring load together with spheroid.Its advantage is to the direct inspect and change valve seat of the valve be contained on pipeline, reduces dead time, increases the benefit.Along with modern develop rapidly, higher requirement is put forward to top-loading ball valve.
When common top-loading ball valve needs when pipeline breaks down to repair, valve need not be dismantled from pipeline, need only to dismantle middle flange bolt and nut, valve gap and valve rod are taken off from valve body, then takes out spheroid and valve seat, just can repair spheroid and valve seat online, but whole title is excessively harder, especially bigbore valve is just more required great effort, and from the two ends of valve body, valve seat will be pulled to the direction away from spheroid, operating space is also restricted.
Model utility content
For above-mentioned defect of the prior art and problem, the object of the utility model embodiment is to provide a kind of top-loading ball valve tool structure of better reliability, thus increases work efficiency.
In order to achieve the above object, the utility model embodiment provides following technological scheme:
A kind of top-loading ball valve tool structure, it is characterized in that, be made up of valve body, multistage collar, valve seat, fixed block, frock and spheroid, valve body is provided with two relative valve seats, be provided with spheroid between two valve seats, fixed block is all equipped with in two ends to valve seat, and frock is nested on fixed block, be provided with multistage collar in the middle of valve seat and valve body, multistage collar is linked to be the annular of an opening by the rotatable Stationary liquid of pin by multistage little radian connecting sheet.
Preferred as technique scheme, described fixed block is made up of fixed plate and screw, and the upper and lower two ends of fixed plate are provided with screw, and one end, two ends, left and right is straight flange, and one end is arc convex.
A kind of top-loading ball valve tool structure that the utility model embodiment provides, compared with prior art, advantage of the present utility model is just: structure is simple, easy to use, screw only need be made to move up and down when dismounting, maintenance, just can field maintenance and renewal part, keep in repair more convenient and swift, increase the service life, especially bring conveniently to underground utility maintenance, save engineering time, the loss in producing is dropped to minimum point.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is the structural representation of the multistage collar of a kind of top-loading ball valve tool structure of the utility model embodiment.
In figure: 1-valve body, 2-multistage collar, 3-pin, 4-valve seat, 5-fixed block, 6-frock, 7-spheroid.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, a kind of top-loading ball valve tool structure, by valve body 1, multistage collar 2, valve seat 4, fixed block 5, frock 6 and spheroid 7 are formed, valve body 1 is provided with two relative valve seats 4, between two valve seats 4, spheroid 7 is installed, fixed block 5 is all equipped with at two ends to valve seat 4, frock 6 is nested on fixed block 5, multistage collar 2 is provided with in the middle of valve seat 4 and valve body 1, multistage collar 2 is linked to be the annular of an opening by the rotatable Stationary liquid of pin 3 by multistage little radian connecting sheet, described fixed block 5 is made up of fixed plate and screw, the upper and lower two ends of fixed plate are provided with screw, one end, two ends, left and right is straight flange, one end is arc convex.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
