[0003] In the preparation of chlorinated paraffin, the chlorinated paraffin prepared in the chlorination kettle has the following problems during discharge: the discharge valve located at the bottom has a certain distance from the bottom of the reaction kettle. Due to the room temperature placement condition, the chlorinated paraffin from the bottom of the reaction kettle to the valve is prone to condensation and solidification, which will block the valve during discharge. Therefore, how to solve the problem of solidified chlorinated paraffin at the valve is an urgent problem to be solved. SUMMARY

[0004] In view of the technical problem that the chlorinated paraffin at the valve is prone to solidification during the discharge of chlorinated paraffin, the utility model provides a valve with heating function to solve the above problems.

[0005] The technical scheme of the utility model is as follows:

[0006] A valve with heating function, comprising a valve body, a valve switch is arranged on one side of the valve body, a wrench is installed on the valve switch, and the valve is opened and closed by rotating the wrench; a detachable heater is arranged outside the valve body, and the heater is hollow; the heater is provided with an air inlet and an air outlet; the heater comprises two heater housings, and the two heater housings are connected through a rotating shaft; a lug is arranged on one side of the heater housing relative to the rotating shaft; the heater is closed by inserting a bolt into the lug.

[0007] Further, a sight glass is arranged on one side of the valve body relative to the discharge port.

[0008] Further, the outer side of the heater is wrapped with heat insulation cotton.

[0009] Further, the valve is a ball valve.

[0010] Further, the air inlet is arranged above the air outlet, and the air inlet and the air outlet are arranged oppositely.

[0011] Further, the rotating shaft is provided with at least two.

[0012] Further, the lug is provided with at least two, and the bolt is provided with at least two.

[0013] The working principle of the utility model is that before chlorinated paraffin is discharged, connect the steam pipeline to the air inlet, connect the steam return pipeline to the air outlet, and open the steam heating.

[0014] The utility model has the advantages of:

[0015] The discharge valve with the heating function has simple structure, the heater which can be disassembled is arranged at the valve, and the valve is heated by introducing external heat source. DRAWINGS
