Abstract
The utility model relates to a temperature control pipeline device of a batch-type pre-foaming machine, which belongs to the field of foam plastic machinery. The steam temperature of the prior art is controlled by a steam main valve, a bottom cleaning valve and a steam auxiliary valve simultaneously, and then the steam temperature is extremely hard to be controlled. The temperature control pipeline device comprises a bottom cleaning valve, a steam auxiliary valve, a steam main valve and a steam inlet pipe, wherein the bottom cleaning valve is connected with the steam auxiliary valve through pipelines, and the steam inlet pipe is connected to the steam main valve. The temperature control pipeline device is characterized by further comprising a compressed air proportional valve, a steam proportional valve and a bypass mixing pipe, wherein the steam proportional valve is connected to the steam main valve through pipelines, the steam auxiliary valve is connected to the steam proportional valve through pipelines, the bypass mixing pipe is connected to the steam inlet pipe, and the compressed air proportional valve is fixed on the bypass mixing pipe. The utility model is reasonable and novel in pipeline, can control steam temperature well, and guarantees the quality of foam products.
Description
Technical field
The utility model relates to a kind of temperature control piper, relates in particular to a kind of temperature control piper device of batch (-type) prefoaming machine, and it belongs to foamed plastics machinery field.
Background technology
Present temperature of the prior art control is to control vapor (steam) temperature simultaneously by steam main valve and bottom purge valve and three valves of the secondary valve of steam, and these three valves all are the apertures with the switching value control valve, exist valve opening at 0 and 100% two class like this, thus the temperature of extremely difficult control steam.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and provide a kind of reasonable in design, can control temperature, the flow that adopts compressed air and steam to cooperatively interact, thus reach the temperature control piper device of batch (-type) prefoaming machine.
The technical scheme in the invention for solving the above technical problem is: a kind of temperature control piper device of batch (-type) prefoaming machine, comprise the bottom purge valve, the secondary valve of steam, the steam main valve, steam enters pipe, wherein said bottom purge valve is connected by the secondary valve of pipeline and steam, described steam enters pipe and is connected on the steam main valve, it is characterized in that: also comprise the compressed air proportioning valve, steam proportioning valve and bypass mixing tube, wherein said steam proportioning valve is connected on the steam main valve by pipeline, the secondary valve of described steam is connected on the steam proportioning valve by pipeline, described bypass mixing tube is connected steam and enters on the pipe, and described compressed air proportioning valve is fixed on the bypass mixing tube.Make the utility model adopt analog quantity to control the temperature of steam thus, avoided switching value control and the phenomenon that air pressure is too high or temperature is unstable occurs.
Bypass mixing tube described in the utility model is fixed by welding in steam and enters on the pipe.
Compressed air proportioning valve described in the utility model is by being threaded in the bypass mixing tube.
The utility model compared with prior art has the following advantages and effect: the utility model increases by two than analog quantity control valve and mixed pipe line, comprises compressed air proportioning valve and steam proportioning valve and mixes bypass conduit.Control piper in the utility model adopts non-opening and pass amount but analog quantity is controlled the temperature of steam, has avoided switching value control and the phenomenon that air pressure is too high or temperature is unstable occurs.
The utility model is put the gas mixing portion to steam main valve shunt valve place, and fully gas mixes, and makes vapor (steam) temperature even, and nearer from air inlet.The utility model circuit design is reasonable, novel, can fine control vapor (steam) temperature, guarantee the quality of froth pulp.
