Abstract
The valve heat-insulating sleeve is applied to oil field valve heat insulation. Is characterized in that: the thickness of the outer resin layer is 1-5 mm, and an inner filling layer is arranged at the outer resin layer; the inner filling layer is arranged between the resin outer layer and the valve, the resin outer layer is divided into two symmetrical shells, the two shells are oppositely folded to form the resin outer layer, the middle part of the shape of the resin outer layer is a cylinder, and the upper end of the cylinder is connected with a truncated cone; two sides of the cylinder are vertically connected with small cylinders extending leftwards and rightwards, and connecting buckles are fixed outside the edges where the two symmetrical shells are folded. The effect is as follows: the heat transfer valve is arranged outside the valve, can effectively prevent heat transfer inside and outside the valve, prolongs the service life of the valve and keeps the valve clean. In addition, the installation is fast, convenient and efficient.
Description
Technical field
The utility model relates to valve heat preservation technology field, oil field, and particularly a kind of valve lagging is a kind of valve lagging that the valve outside has sand prevention, heat insulation function that is buckled in.
Background technique
At present, oil gas field has oil transportation, gas transmission line, and many valves are installed on the pipeline.Pipeline and valve all need to wrap up thermal insulating material.Promptly twine parcel insulation asbestos, be wrapped with iron sheet at the insulation asbestos at pipeline and valve place.Heat-preservation cotton and iron sheet overcoat heat insulation work amount is big, efficient is low, insulation asbestos and outsourcing iron sheet material lifetime are short, need frequently to change.The valve place parcel thermal insulating material expense of taking a lot of work is especially expected, and is also not attractive in appearance behind the parcel.Waste and old asbestos serious environment pollution, infringement enterprise employee health increase labor intensity and maintenance cost.
The model utility content
The purpose of this utility model provides a kind of valve lagging, can carry out the valve insulation efficiently and easily, and the workload that overcomes valve place parcel asbestos and iron sheet is big, efficient is low, the deficiency that the thermal insulating material life-span is short.
The technical solution adopted in the utility model is: the valve lagging, mainly form by resin skin and interior packed layer.It is characterized in that: the outer field thickness of resin is between 1～5 millimeter.There is interior packing course in outer field portion at resin.Interior packing course is between resin skin and valve.The resin skin is divided into two shells of symmetry, becomes the resin skin after two shells close up relatively.The outer field profile of resin is that the middle part is a cylindrical body, connects a circular cone in cylindrical upper end.The small column that vertically is connected with left, stretches out to the right in cylindrical both sides.The edge external stability that is folded at two shells of symmetry has the connection buckle, and the effect that connects buckle is that two shells of symmetry are connected.
After two shells were closed up relatively, the handle of valve can be exposed on the outside, and center hole is arranged at the circular cone top that described cylindrical upper end connects.
After two shells are closed up relatively, do not influence the connecting line of valve, described cylindrical both sides left, the small column that stretches out to the right has center hole.
The utility model valve lagging working process:
Gather the valve profile, set up valve lagging mould, fleece is done the top layer skeleton on mould, be coated with good with plasticity, that intensity is high is transparent, heat resistance, AS resin (AS) material that oil resistance is high, treats its hardened forming, becomes the resin skin.Interior packing course is selected the low incompressible polyurethane elastomer material of porous crack thermal conductivity.Each valve lagging will be incubated retaining ring and be anchored on the valve by two parts of symmetry during installation, locked then quick connection buckle is just finished the valve heat insulation work.
The beneficial effects of the utility model: the utility model valve lagging, be installed in the valve outside, can effectively stop the inside and outside heat of valve to be transmitted, because of its adopt low material of thermal conductivity and special structure more its sealing configuration can effectively stop sand and dust to enter in the valve and prevent the convection heat exchange of gas in the valve lagging, prolong valve working life, kept the valve cleaning.In addition, have install fast, convenient, efficient is high, the material innocuousness of use and once drop into permanent the use has been protected environment and is avoided health effects has been reduced cost, reclaims conveniently.

Embodiment
Embodiment 1: with a valve lagging is example, and model utility is described in further detail.
The utility model valve lagging mainly is made up of resin outer 1 and interior packed layer 2.Consult Fig. 4.The thickness of resin skin 1 is 2 millimeters.Packing course 2 in the portion of resin skin 1 has, and interior packing course 2 is filled between resin outer 1 and the valve.
Consult Fig. 2 and Fig. 3.Resin skin 1 is divided into two shells of symmetry, becomes resin skin 1 after two shells close up relatively.Consult Fig. 1.The profile of resin skin 1 is that the middle part is a cylindrical body, 70 millimeters of cylindrical body external diameters, 85 millimeters of height.Connect a circular cone in cylindrical upper end.A center hole is arranged at the circular cone top that cylindrical upper end connects.The small column that vertically is connected with left, stretches out to the right in cylindrical both sides, the external diameter of small column are 50 millimeters, 30 millimeters of length.Cylindrical both sides left, the small column that stretches out to the right respectively has a center hole.Consult Fig. 1.The edge external stability that is folded at two shells of symmetry has 5 to connect buckle 3, and the effect that connects buckle 3 is that two shells of symmetry are connected.
After building a station in the basin 5 natural gas processing stations that are located in the innerland, desert, this kind valve lagging on probation, lagging is excellent since building a station, heat-transfer coefficient is lower than the heat-preservation cotton heat-transfer coefficient, high insulating effect and effectively stop entering of dust storm in the desert never occurs once damaging incident because of dust storm causes valve invalidation.
