Abstract
The utility model relates to a liquid supply device with low-pressure circulation, comprising a low-pressure circulation bucket. The liquid supply device with the low-pressure circulation is characterized in that the upper part of the low-pressure circulation bucket is provided with a high liquid level floater, the middle part of the low-pressure circulation bucket is provided with an intermediate liquid level floater, the lower part of the lower-pressure circulation bucket is provided with a low liquid level floater, the floater is provided with a liquid level sensor, and a liquid supplementing pipe of the low-pressure circulation bucket is provided with an electromagnetic valve. The device can realize automatic liquid supply with low-pressure circulation, not only is simple in structure, convenient for operation, but also can effectively ensure running safety of equipment.
Description
Technical field
The utility model relates to a kind of liquid feed device, particularly a kind of refrigeration system mesolow circulation liquid feed device.
Background technology
Refrigeration is to circulate in a closed-system by cold-producing medium, constantly changes its state, thereby acquisition low temperature.The feed liquid way of low pressure recycle bucket mainly adopts manual feed flow at present, and with manually control, the excessive phenomenon of feed flow deficiency and feed flow appears in inconvenient operation easily.
Summary of the invention
The purpose of this utility model is to provide a kind of low pressure recycle liquid feed device, and this device can be realized the automatic liquid supply of low pressure recycle, and is not only simple in structure, easy to operate, and can effectively guarantee the security of operation of equipment.
The technical solution of the utility model is: a kind of low pressure recycle liquid feed device, comprise the low pressure recycle bucket, it is characterized in that: the top of described low pressure recycle bucket is provided with high liquid level ball float, the middle part of low pressure recycle bucket is provided with middle liquid level ball float, the bottom of low pressure recycle bucket is provided with low liquid level ball float, described ball float is provided with liquid level sensor, and the liquid supplementation pipe of described low pressure recycle bucket is provided with magnetic valve.
Advantage of the present utility model is: can regulate the feed flow operation automatically according to the liquid level in the liquid-supplying bucket, when the too high feed flow automatic cut-off of liquid level, liquid level is crossed and can be carried out replenishing of liquid when hanging down automatically, and equipment manufacturing cost is low, highly versatile, energy consumption is low, simple and practical, the safety that operates steadily, automation degree of equipment improves, stable, greatly reduce the maloperation of artificial liquid feeding.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of low pressure recycle liquid feed device, comprise low pressure recycle bucket 1, it is characterized in that: the top of described low pressure recycle bucket is provided with high liquid level ball float 2, the middle part of low pressure recycle bucket is provided with middle liquid level ball float 3, the bottom of low pressure recycle bucket is provided with low liquid level ball float 4, described ball float is provided with liquid level sensor 5, and the liquid supplementation pipe 6 of described low pressure recycle bucket is provided with magnetic valve 7.
Operation principle of the present utility model is as follows: the ball float in the low pressure recycle bucket is the liquid level sensor of corresponding differing heights respectively, consumption along with circulation fluid, when liquid level reaches low liquid level ball float when following, the suffered buoyancy of ball float changes, thereby triggering sensor sends the signal controlling magnetic valve and opens and carry out replenishing of liquid, when replenishing when meeting or exceeding high liquid level ball float, trigger sensor and send the signal controlling closed electromagnetic valve, feed flow stops.According to the different control automatically of the height of liquid in low pressure recycle bucket feed flow, can effectively solve the manually operated problem of bringing.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
