Abstract
The utility model discloses a self-vertical type vapor adjusting device of a liquid ammonia evaporator. The liquid ammonia evaporator is internally provided with a liquid ammonia coil tube and a vapor coil tube, wherein a self-vertical type vapor adjusting valve is arranged on an inlet pipeline of the vapor coil tube of the liquid ammonia evaporator and is connected with the inlet pipeline of the vapor coil tube through a flange; a probe rod of the self-vertical type vapor adjusting valve is horizontally arranged in the middle of the liquid ammonia evaporator and is connected with the liquid ammonia evaporator body in a sealed manner through thread pieces; a probe rod end stretches into the liquid ammonia evaporator body; the probe rod is connected with the self-vertical type vapor adjusting valve through a length sensing hose. The self-vertical type vapor adjusting device has the advantages that the self-vertical type vapor adjusting device is simple in structure, easy to operate, low in cost and safe and reliable in operation due to the fact that hot medium water inside the liquid ammonia evaporator is effectively prevented from being boiled as the vapor flow of the self-vertical type vapor adjusting valve can be automatically adjusted through the probe rod of the self-vertical type vapor adjusting valve and the length sensing hose without external compressed air or external power supply.
Description
(1) technical field
The utility model relates to power plant liquefied ammonia station auxiliary equipment, particularly a kind of steam self-support adjusting device for liquid ammonia evaporator.
(2) background technology
In power plant liquefied ammonia station equipment, generally include coiled liquid ammonia evaporator, by the liquefied ammonia coil pipe that arranges in liquid ammonia evaporator and the indirect heat exchange of steam pipe coil, make liquid ammonia gasification.For preventing the heat medium water boiling of liquid ammonia evaporator inside, conventionally in steam pipe coil import, a steam control valve is set, control the pressure and temperature of steam, realize the temperature of controlling heat medium water.Steam control valve is installed on pipeline needs external compressed air and external power supply, will inevitably increase equipment early investment cost and equipment later stage operating cost.
(3) utility model content
The purpose of this utility model is for above-mentioned existing problems, a kind of steam self-supporting adjusting device for liquid ammonia evaporator is provided, this apparatus structure is simple, cost is low, safe and reliable to operation, avoid the generation of equipment later stage operating cost, reach the object of reduction equipment operating cost.
The technical solution of the utility model:
A kind of steam self-supporting adjusting device for liquid ammonia evaporator, in described liquid ammonia evaporator, be provided with liquefied ammonia coil pipe and steam pipe coil, it is characterized in that: on the suction line of the steam pipe coil of liquid ammonia evaporator, be provided with steam self-supporting regulation valve and be connected with the suction line of steam pipe coil by flange, the probe of steam self-supporting regulation valve is horizontally placed on the middle part of liquid ammonia evaporator and is tightly connected by screw element and liquid ammonia evaporator body, liquid ammonia evaporator body inside is stretched in probe termination, and probe is connected by length sensing flexible pipe with steam self-supporting regulation valve.
The utility model has the advantages that: this steam self-supporting adjusting device forms simple, easy to implement and cost is low; By the variations in temperature of heat medium water in the probe transmission fluid ammonia evaporator of steam self-supporting regulation valve, and then utilize the steam flow of the length variations steam regulation self-supporting regulation valve that length sensing flexible pipe expands with heat and contract with cold, do not need external compressed air and external power supply, can effectively prevent the heat medium water boiling of liquid ammonia evaporator inside, safe and reliable to operation, can in liquid ammonia evaporator, be widely used.
