Abstract

The utility model discloses a constant temperature electric heating valve for discharging asphalt liquid, which is characterized in that a constant temperature electric heating device is arranged at the bottom of a valve body. The constant temperature electric heating device consists of a temperature-limiting electric heater and an automatic thermostat, the limited temperature is below 105 ℃, the heat preservation is between 60 ℃ and 100 ℃, and the constant temperature electric heating device has the characteristics of safe and convenient use, reduction of the labor intensity of workers, improvement of the production efficiency of asphalt transportation and boiling, and maintenance of no pollution to the working environment and no deterioration of the asphalt. The asphalt melting device is suitable for asphalt storage, transportation, melting and other equipment of highway and urban construction departments, and has use and development values.

Description

The constant temperature electric heating asphalt valve
The utility model relates to a kind of constant temperature electric heating valve that is used to discharge asphaltic liquid.
At present, the valve that adopted of highway in China and coal tar field that urban construction department had jurisdiction over and enduring workshop generally is plain cast iron stop valve or gate valve.This valve arrangement is simple, low price, but, thereby usually when enduring or conveying asphalt, need heat valve body with firewood or fuel lance, institute heeltap green grass or young crops in the softener valve, the interior oil discharge passage of unimpeded valve because pitch condensation below 40 ℃ the time can not be flowed.Like this, not only labor intensity is big, and work efficiency is low, and pollutes working environment, influences the healthy of workman, also causes fire accident easily simultaneously, is unfavorable for safety in production.
The purpose of this utility model provides a kind of constant temperature electric heating asphalt valve of safe and sanitary easy to use.
The purpose of this utility model is achieved in that it is provided with the constant temperature electric heating device in the bottom of common valve body.This constant temperature electric heating device mainly is made up of warm electric heating apparatus of limit and automatic thermostat parallel circuit.Limit warm electric heating apparatus to be made up of the magnetic steel temperature limiter and the series circuit of heating electric heating tube, automatic thermostat then is made up of the bimetal insulation switch and the series circuit of insulation electric heating tube.
For example, when the needs bi tumenf orr oad flows out, connect power supply from valve body, limit the heating electric heating tube of warm electric heating apparatus just to begin valve body is heated, make the interior condensation pitch of valve softening.When the valve body temperature rises to 45 ℃-60 ℃, open valve and can discharge pitch.When the valve body temperature reached 101 ℃-105 ℃, magnetic steel temperature limiter auto power off, electric heating apparatus stopped heating, and the valve body temperature then begins to descend.When temperature was reduced to 60 ℃, the bimetal release auto-closing was connected power supply, and the heating of insulation electric heating tube is carried out the low-grade fever insulation to valve body, flowed thereby make the interior pitch of valve not agglutinate and continue.
The utility model compared with prior art has following advantage:
Because electric heater directly closely contacts with valve body, heat leakage is few, and thermal efficiency height can improve the valve body temperature in a short period of time rapidly and flow out to pitch is softening.The cooperation control of magnetic steel temperature limiter and automatic heat preserving device is arranged again, guaranteeing to flow through valve body pitch non-ageing again while of condensation neither, fundamentally eliminated owing to use the artificial heating outside valve of firewood or fuel lance, temperature is difficult for grasping the pitch evaporation that causes even burns and the poison gas of generation and the hidden danger of fire, not only economize on electricity is saved trouble, alleviated working strength of workers, improved working efficiency, reduced cost of production, and reduced environmental pollution, help the healthy of workman and safety in production.The utility model is not only applicable to many facilities of highway and urban construction department pitch smelter, also can be used for pitch storage tank, train, automobile pitch transfer cask, equipment such as pitch oil sump and enduring workshop, its applied range has excellent development use value and prospect.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a constant temperature electric heating apparatus structure schematic representation of the present utility model.
Fig. 3 is an electrical schematic diagram of the present utility model.
Describe concrete structure of the present utility model in detail below in conjunction with drawings and Examples.
Referring to Fig. 1-3, it comprises valve body 1, and the bottom of valve body 1 is a concave curved surface shape, to increase hot area.Connect the constant temperature electric heating device 2 that a profile is a disk stove sample at the concave surface place of valve body 1 bottom.Constant temperature electric heating device 2 mainly is made up of the parallel circuit of warm electric heating apparatus of limit and automatic thermostat.Limit warm electric heating apparatus to be made up of the magnetic steel temperature limiter 10 and the series circuit of heating electric heating tube, automatic thermostat then is made up of the bimetal insulation switch 11 and the series circuit of insulation electric heating tube 9.It also comprises the metal shell 3 that is connected with valve body bottom and the insulated thermal insulating layer 4 in the shell, and shell 3 is provided with power socket hole 5, burner on light 6 and be incubated tutorial light 6 ' and temperature limit switch 12, burner on light 6 and resistance R 1Be connected in parallel on after the series connection on the bimetal insulation switch 11, and insulation tutorial light 6 ' and resistance R 2Be connected in parallel on after the series connection on the temperature limit switch 12.Being provided with the top in metal shell 3 is the electric-heating plate 7 of sealed type, the concave surface that the top of electric-heating plate is at the bottom of convex-shaped and the valve matches, in electric-heating plate 7, lay heating electric heating tube 8 and insulation electric heating tube 9 respectively, and settle magnetic steel temperature limiter 10 in the central authorities of electric-heating plate 7, the inductive head of magnetic steel temperature limiter should be close to the valve body bottom, is provided with bimetal insulation switch 11 below magnetic steel temperature limiter 10.Heating electric heating tube 8 and insulation electric heating tube 9 together are cast in the middle of the disk body when casting electric-heating plate 7, have so not only strengthened mechanical strength, but also have had corrosion resistance preferably, thermal conductivity and good insulation performance.The power of electric heating tube 8 is decided by the size of valve body model, is generally 50W-2000W, also can be as required greater than 2000W.Temperature that the utility model is limit is between 103 ± 2 ℃, and insulation is generally between 60 ℃-100 ℃.But also can adjust bimetal insulation switch and control minimum holding temperature according to the pitch kind.
