Abstract
The utility model relates to a direct heating type preheating device for a gas pressure reducer, which is connected with the pressure reducer of a high-pressure gas cylinder. Helical heating gas holes are arranged around a heating body in a pressure reducing valve body, and a sealing sleeve is arranged between the contact surfaces of the heating body and the pressure reducing valve body to prevent the gas from overflowing. When the utility model has two or more heating bodies, the heating gas holes are connected in series. The utility model has the advantages of small size, small heating power, high thermal efficiency, and short initial heating time, being applicable to the pressure reducers of various high-pressure liquid-state body bottles.
Description
The utility model relates to a kind of liquid gas gasification Preheating unit, particularly a kind of direct-heating type gas pressure reducer Preheating unit that is connected with the gas cylinder decompressor.
Existing gas pressure reducer gives thermic devices and is the indirection type mode of heating.No matter they adopt electric heating coil still is the electrical bar heating element, its structure all be heating air flue in the valve body and heating element away from, make heating element heating decompressor valve body earlier, heat gas in the air flue in heat conducting mode again.The heating power that therefore this indirection type heating equipment needs is big, and the thermal efficiency is low, and first heating time is long, and requires to have bigger valve body accumulation of heat could satisfy the demand of air feed heating.
The purpose of this utility model provides in a kind of decompressor valve body and with the heating unit position contacting heating pore is set, and installs in advance so that gas can directly absorb the direct-heating type gas pressure reducer of heating element heat, to overcome deficiency of the prior art.
The purpose of this utility model is achieved through the following technical solutions.
Direct-heating type gas pressure reducer Preheating unit is one or more heating units 2 of packing in decompressor valve body 4, and heating pore 1 is set, and leaves a suction port 7 and an air outlet 8 outside valve body.Heating pore of the present utility model is a spirality, spirals between the surface of contact of each heating unit and valve body, does not also have stuffing box gland between heating unit and valve body.Each spiral heating pore connects with serial fashion by the duct 5 in the valve body.
Below in conjunction with embodiment of the present utility model and accompanying drawing, the pre-device of direct-heating type gas pressure reducer is described in detail.
Fig. 1 Preheating unit sectional view;
Fig. 2 ring set stuffing box gland partial schematic diagram.
The stuffing box gland of Preheating unit can be a thin-walled jacket casing 3, with the base ring shape end face of oral area shoulder as sealing surface.
The stuffing box gland of Preheating unit can also be a ring set 10 that is sleeved between heating unit and the valve body oral area, and its internal diameter and base ring shape end face are as sealing surface.
The spiral heating pore 1 of Preheating unit can be positioned at valve body hole, or on the heating unit external diameter, when thin-walled jacket casing stuffing box gland is arranged, also can be positioned on the external diameter of jacket casing.
Fig. 1 is given the Preheating unit example of heating extracorporeal set thin-walled jacket casing stuffing box gland.Heating resistance collar adopts electrical bar, process spiral heating pore 1 on the stuffing box gland external diameter, be provided with duct 5 in the valve body between two heating units 2, and connect two spiral heating pores, make the gas that enters from import 7, discharge from exporting 8 through the heating pore 1 and 5 backs, duct of series connection.Part 6 is stifled for technology.
The utility model in the course of the work, heating element is heating high-pressure gas directly, simultaneously with waste heat heating decompressor valve body, makes not only direct heated air of Preheating unit, also makes full use of waste heat and carry out the transmission of heat heating.For the Preheating unit that the thin-walled jacket casing is installed, because heating pore position is very thin apart from the wall thickness of heating unit, be only to be provided with for conveniently sealing, therefore still can realize direct mode of heating.
This device has that volume is little, and heating power is little, thermal efficiency height, and first heat time heating time short advantage. Be suitable in multiple high-pressure liquid gas bottle pressure reducer preheating device, using, for example in carbonic anhydride gas pressure reducer, use.
