Description
Technical field
The utility model relates to the technical field of gas filter drain cock, particularly a kind of gas filter drain cock with thermal insulation apparatus.
Background technique
Gas filter drain cock is indispensable a kind of device on fed sheet of a media pipeline; usually the entrance point of reduction valve, Decompression valves, normal valve or miscellaneous equipment is arranged on; be used for eliminating the impurity in medium, to protect the normal use of valve and equipment, reduce the device of equipment maintenance cost.In order to avoid the loss of equipment, when temperature is lower, need to carry out isothermal holding to gas filter drain cock, at present, the insulation of gas filter drain cock adopts vapor heated mode (telescopic insulation) more, need at the additional Steel Sleeve of gas filter drain cock filler, in sleeve pipe, logical steam, reaches heat insulation effect, but, the shortcoming of this heat preserving mode is, maintenance load is large, and causes the waste of thermal source.
Model utility content
In order to overcome the deficiencies in the prior art, devise a kind of gas filter drain cock with thermal insulation apparatus, structure is simple, and investment cost is few, gas filter drain cock long service life, energy-conserving and environment-protective.
The technical solution adopted in the utility model is; a kind of gas filter drain cock with thermal insulation apparatus; comprise gas filter drain cock body; gas filter drain cock body outer surface is provided with thermal insulation apparatus; key is: described thermal insulation apparatus is the first thermal insulation layer and the second thermal insulation layer that are successively set on gas filter drain cock body outer surface from inside to outside; first thermal insulation layer fits tightly the outer surface at gas filter drain cock body; between the first thermal insulation layer and the second thermal insulation layer, be provided with fixing chain link fence, be coated with protecting sheathing in the outside of the second thermal insulation layer.
The first described thermal insulation layer is the rock cotton board of fissure of displacement overlap joint from top to bottom, and the thickness of the first described thermal insulation layer is 100mm.
The second described thermal insulation layer is ganoid heat insulation coating, and the thickness of the second thermal insulation layer is 20mm.
Described fixing chain link fence is hexagonal galvanized wire mesh, and the size of mesh of fixing chain link fence is 80 × 100mm.
Described protecting sheathing is ganoid galvanized sheet iron, and the thickness of protecting sheathing is 0.6mm.
The beneficial effects of the utility model are, structure is simple, and thermal insulation layer and gas filter drain cock are designed to one, this avoid some puzzlements during maintenance of traditional coal air filter; Effectively saved the use of steam thermal energy simultaneously; The design of multi-layer heat preserving layer, makes the longer service life of gas filter drain cock; Cost of investment is few, is convenient to promote the use of.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In accompanying drawing, 1 is gas filter drain cock body, and 2 is first thermal insulation layers, and 3 is second thermal insulation layers, and 4 is fixing chain link fence, and 5 is protecting sheathings.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Specific embodiment, as shown in Figure 1, a kind of gas filter drain cock with thermal insulation apparatus, comprise gas filter drain cock body 1, gas filter drain cock body 1 outer surface is provided with thermal insulation apparatus, key is: described thermal insulation apparatus is the first thermal insulation layer 2 and the second thermal insulation layer 3 being successively set on gas filter drain cock body 1 outer surface from inside to outside, first thermal insulation layer 2 fits tightly the outer surface at gas filter drain cock body 1, the first described thermal insulation layer 2 is the rock cotton board of fissure of displacement overlap joint from top to bottom, the thickness of the first described thermal insulation layer 2 is 100mm, fixing chain link fence 4 is provided with between the first thermal insulation layer 2 and the second thermal insulation layer 3, described fixing chain link fence 4 is hexagonal galvanized wire mesh, the size of mesh of fixing chain link fence 4 is 80 × 100mm, iron wire diameter is 2.0mm, the second described thermal insulation layer 3 is ganoid heat insulation coating, the thickness of the second thermal insulation layer 3 is 20mm, protecting sheathing 5 is coated with in the outside of the second thermal insulation layer 3, described protecting sheathing 5 is ganoid galvanized sheet iron, the thickness of protecting sheathing 5 is 0.6mm.
The utility model is when specifically using: be provided with thermal insulation apparatus at gas filter drain cock outer surface, be followed successively by from inside to outside, and the first thermal insulation layer is thermal insulating material rock cotton board, fits tightly at outer surface; Between the first thermal insulation layer and the second thermal insulation layer, tie up hexagonal galvanized wire mesh, be wrapped in outside rock cotton board securely; Second thermal insulation layer is heat insulation coating, and adopt asbestos, perlite powder, cement mixing and stirring even, be coated on thermal insulation layer, coating surface is smooth, without crack performance; Ganoid galvanized sheet iron protecting sheathing is coated with in the outside of the second thermal insulation layer; can ensure that the impurity (tar, water etc.) filtered in gas filter drain cock does not freeze; gas filter drain cock can be protected again appearance can not to be corroded because of the use of steam, to increase the working life of gas filter drain cock.In gas filter drain cock using process, inside temperature is higher than external temperature, the heat insulation effect that the thick rock cotton board of 100mm plays, reduce over the radiation loss of filter surface, ensure the normal use of filter, thermal insulation layer does not need to safeguard, than a little repair of steam insulation yet at ordinary times, and use steam, the appearance of gas filter drain cock is not easily corroded.
