Abstract
The utility model discloses a rail heater which uses a hose to join a heater body and a mixing chamber. The mixing chamber can be put into water and can not be burned out even the backfire. The heater body has the advantages of simple gas path and reasonable gas distribution. Thereby, the flame is straight and strong.
Description
The utility model belongs to the improvement of soldering appliance.
Prior art of the present invention be adopt on the railway " mobile gas pressure welding welded rails new technology welding gapless track joint connector, its used rail heater has two kinds of forms, a kind of is whole open-type, a kind of is opposite opened.Their common shortcomings are that (1) gas mixer chamber and heater body are that mechanical attachment is integral; (2) gaseous mixture enters gas circuit complexity after the heated air.Be the heater configuration complexity, manufacture difficulty is big, the cost height.
The utility model is a kind of novel soldering appliance, can overcome the shortcoming of above-mentioned heater.(1) gas mixer chamber is two bodies that are connected with flexible pipe with heater body; (2) gas circuit in the heater body is simple.Therefore heater configuration is simple, easy to manufacture.Cost can reduce half.
The effect that the utility model is formed gas mixer by heater body (Fig. 1) and gas mixer chamber (Fig. 2) two parts is that oxygen and combustible gas are evenly mixed in proportion.The effect of heater body is that the gas that will mix is transported to each position on demand.By the fire hole ejection, form required flame rail is heated again, make the temperature rise of rail each several part consistent basically.Because there is cooling water to pass through in the heater body, make mixer temperature not high, thereby heater has guaranteed that flame can normal combustion.Heater (Fig. 1) is made up of cooling water inlet joint (1) (10) and coolant outlet joint (4) (7), flexible pipe (2) (9), fire hole (11), mixture pipe (12), water cooling chamber (13), inlet suction port (3) (8) and heated air (5) (6).Gas mixer chamber (Fig. 3) is made up of mixed gas outlet joint (14) (19), junctor (15), mixing chamber (16), oxygen connection (17) and acetylene gas joint (18).During work, oxygen and acetylene gas enter mixing chamber (16) by joint (17) and (18) respectively, fully mix within it, enter heated air (5) (6) by air outlet adapter (14) (13) through flexible pipe (2) (9) and inlet suction port (3) (8) again, again by fire hole (11) ejection formation flame, the tempering in order to prevent gaseous mixture to be heated, water cooling chamber (13) outside mixture pipe (12), cooling water flows within it, make the gaseous mixture temperature rise not high, thereby guaranteed the flame normal combustion, when rail is heated to a certain degree, it has just finished welding job.
The utility model has outstanding advantage than prior art.(1) gas mixer chamber is two bodies that are connected with flexible pipe with heater body; (2) gas circuit in the heater body is simple.Can put into water by the mixing chamber that cost is higher during use, even tempering can not burnt out yet, simple structure, easy to manufacture, cost reduces half.
1 and 10,4 and 7 are respectively cooling water inlet and outlet connection, 2 and 9 and are heater body for inlet suction port, 5 and 6 for flexible pipe, 3 and 8 in the accompanying drawing 1.11 is that fire hole, 12 is that mixture pipe, 13 is cooling water chamber in the accompanying drawing 2.14 and 19 is that mixed gas outlet joint, 15 is that junctor, 16 is that mixing chamber, 17 is that oxygen connection, 18 is the acetylene gas joint in the accompanying drawing 3.
Claims (1)
- A kind of rail heater of being made up of gas mixer chamber body and heater body is characterized in that its heater body is made up of mixture pipe, fire hole, cooling water chamber, turnover gas joint and Inlet and outlet water joint; The gas mixer chamber body is made up of mixing chamber, junctor, turnover gas joint and flexible pipe, and heater body and gas mixer chamber are by soft pipe connection.
