Description
Technical field
The present invention relates to Protection Product technical field, particularly relate to a kind of Cooling vest.
Background technology
In the high temperature or field work situation of the much equipment that can not install an air-conditioner, serious heat stress makes the functions such as the body heat regulation especially of the physiological function of people, water-electrolyte metabolism, blood circulation all can occur abnormal change, light then reduce operating efficiency, affect judgment, serious meeting causes heatstroke, even threat to life safety.For solving the problem, Cooling vest arises at the historic moment.
The Cooling vest of existing employing cooling water circulation, what adopt is that cooling tube is wrapped in Cooling vest, or film is set and is wrapped in waist, and pipeline is set in film to realize cooling water circulation, this Cooling vest, have poor air permeability, cooling area distribution uneven, simultaneously heavy, wear uncomfortable, rely on the shortcomings such as water source simultaneously.
The mode of adding low-temperature receiver in vest is separately had to realize cooling.This Cooling vest can freely be carried with, and is applicable to wearing next to the skin, and cold distributes evenly, recycle by adding low-temperature receiver, volume is little, lightweight, without worry of bearing a heavy burden, but this Cooling vest cooling efficiency is low, especially in higher temperature environment, low-temperature receiver can be consumed, and the cooling-down effect duration is shorter, especially in the wild, low-temperature receiver cannot long-time storage and short time recovery.
Therefore the individual temp .-lowering heatstroke vest needed badly as hot operation personnel, field man provide a kind of lightweight, safety and health temp effect good.
Summary of the invention
The object of the invention is hot operation personnel, field man provide a kind of lightweight, individual temp .-lowering heatstroke vest that safety and health temp effect is good, concrete summary of the invention is as follows:
A kind of Cooling vest, it is characterized in that comprising vest body, holding vessel and mozzle, described vest body is connected by mozzle with holding vessel, and described holding vessel is provided with holding vessel switch, and stores low-temperature receiver; The tank body perforate of described holding vessel, described tapping is provided with pressure relief device; Described pressure relief device comprises pressure relief plate and fixture, and described pressure relief plate is arranged on holding vessel tapping by fixture.Design like this, when human body feels sweltering heat, opens holding vessel switch, and pressure reduces, and part low-temperature receiver enters vest body and health carries out heat exchange, plays the effect reducing human body temperature., when can avoid working under the high temperature conditions, there is the excessive danger causing tank body to explode of pressure in tank body in the setting of pressure relief device.
Further, described fixture is flange; A ring flange of described flange is welded on tank body opening part; Described pressure relief plate is arranged in the middle of two ring flanges.Setting like this, when the limiting pressure that pressure can bear higher than pressure relief plate, pressure relief plate is broken, and release gas carries out pressure release, avoids blast.The limiting pressure that pressure relief plate can bear is less than and the limiting pressure of exploding close to tank body.
Further, described ring flange is connected with protective cover.Work as hypertonia, when pressure relief plate is broken, protective cover effectively can be avoided pressure relief plate to splash and cause damage to user or other people.
Further, described low-temperature receiver is liquid carbon dioxide.Liquid carbon dioxide is a kind of cold-producing medium, can absorb a large amount of heat during evaporation, and its heat of vaporization is 578kJ/kg.Carbon dioxide is nontoxic, and discharge does not pollute the environment, simultaneously liquid carbon dioxide low price.
