Abstract
The invention discloses a heat preservation mechanism for a valve. The heat preservation mechanism comprises a left half pipe, a left perpendicular half pipe, a right half pipe, a right perpendicular half pipe and a heat preservation lining, wherein the left half pipe and the left perpendicular half pipe are connected to form a left cavity; the right half pipe and the right perpendicular half pipe form a right cavity; the left cavity and the right cavity are connected to form a heat preservation cavity; the heat preservation lining is arranged in the heat preservation cavity; left bosses are arranged at two ends of the left perpendicular half pipe; right bosses are arranged at two ends of the right perpendicular half pipe; square slots are formed in the left bosses; threaded holes are formed in the right bosses. The heat preservation mechanism also comprises stress blocks consisting of rubber; the stress blocks are arranged in the square slots; threaded through holes are formed in the bottoms of the square slots; bolts penetrate through the stress blocks and are matched with the threaded through holes and the threaded holes. Due to the stress blocks, the rigid connection of a heat preservation sleeve is changed into flexible connection; during mounting and dismounting, the stress blocks can alleviate interaction force between the left perpendicular half pipe and the right perpendicular half pipe, so that the stress degree on the bolts can be reduced, the overuse of the bolts is avoided, and the stability of the heat preservation sleeve is guaranteed.
Description
Technical field
The present invention relates to a kind of lagging, specifically refer to a kind of valve heat insulation mechanism.
Background technique
Valve is in fluid system, be used for controlling direction, the pressure of fluid, the device of flow, be controlling component in pipeline fluid transporting system, be used for changing path section and media flow direction, there is the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.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 be 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 relies on driving or automechanism to make open-shut device do lifting, slippage, swing or rotation motion, thereby the size that changes its Flow area is to realize its control function.
In petroleum pipeline transportation process, particularly, in outdoor pipe transportation, the Insulation of valve is even more important, otherwise can cause oil to condense, and causes line clogging, and then affects the conveying efficiency of oil; Valve insulating sleeve is in an important heating position, but valve heat insulation often becomes again a weak link in insulation, when valve is carried out to dismounting, the thermal insulating material being often arranged on valve becomes the difficult point that valve is safeguarded, when maintenance of valve, cover lagging thereon need be taken off, after being enclosed within the not timing maintenance of valve, usually there is bolt stripped thread in the glass fibre reinforced plastic insulation that used on the market at present, and then cause housing fixing improper, the heat insulation effect that causes valve declines, and is also seriously affected the working life of lagging simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of valve heat insulation mechanism, facilitate the insulation of valve in petroleum pipeline transportation, the working life of improving lagging.
Object of the present invention is achieved through the following technical solutions:
A kind of valve heat insulation mechanism, comprise left semicanal, left vertical semicanal, right semicanal, right vertical semicanal and insulation lining, left semicanal connects and composes left cavity with left vertical semicanal, right semicanal forms right cavity with right vertical semicanal, left cavity and right cavity connect and compose incubation cavity, in incubation cavity, be provided with insulation lining, two ends at the vertical semicanal in a described left side are provided with left projection, the two ends of the vertical semicanal in the described right side are provided with right projection, in left projection, have square groove, in right projection, be provided with tapped hole, also comprise force block, described force block consists of rubber, force block is placed in square groove, the bottom land of square groove has tapped through hole, bolt-through force block coordinates with tapped through hole and tapped hole.When lagging is used at present, be often bolted, but when valve dismounting or maintenance, lagging originally usually also can be by installing/dismounting ceaselessly, and then the screw thread that causes bolt is excessively used and causes bolt impaired, reduced the working life of lagging, and the lagging more renewing makes again cost of production increase, the present invention is with bolts equally, left cavity and right cavity connect and compose incubation cavity, insulation lining is installed in incubation cavity valve is incubated to processing, in left projection, have square groove, the force block of quality of rubber materials is placed in square groove, the bottom of square groove has tapped through hole, in right projection, be provided with tapped hole, bolt-through force block coordinates and makes a left side with tapped hole, right cavity interconnects, by force block, make a left side, the connection of right cavity becomes and flexibly connects from being rigidly connected, when installation and removal, force block can reduce a left side, interaction force between right cavity, reduce the stressed degree of bolt, avoid the excessive use of bolt, guarantee the stability of lagging when long-term use.
