Description

Communicated heat-locking device

Technical field

The utility model relates to the solar water heater accessory, is specifically related to be installed in the communicated heat-locking device on the solar water container passage.

Background technology

The domestic solar water heater is widely used in the daily life with characteristics such as its convenience, material benefit, environmental protections.The water tank of solar water heater uses in outdoor mounted, and the insulation of its water tank is required also along with the universal of solar water heater is more and more higher.From heat preservation effect, heat radiation mainly is passage and pipeline heat conduction and heat radiation, and passage is first source of heat release, and 80% heat distributes from passage.The hot gas of nature makes progress, in order to reduce thermal losses, below desirable blow vent is forced to change into, heat preservation effect has been many, can bring fatal hidden danger simultaneously, following ventilation is to stretch to the top of water tank by the water in the water tank with tracheae in the bottom of water tank, water during water in the water tank reduces, inflate in water tank from passage, when the water in the water tank has been heated water vapour, steam will pass through the downward exhaust of tracheae, not having certain downforce is can not discharge gas, steam can the blast pipe inwall condense into the globule from exhaust outlet to dirty, can be too low and icing when flowing to down exhaust outlet because of the temperature in winter, will following exhaust outlet be blocked slowly taken out flat water tank because of air-filled pore blocks during water again.

Summary of the invention

The purpose of this utility model is: a kind of communicated heat-locking device is provided, locks on the passage that hot device is installed in solar water container, both can exhaust outside water tank, and again can air inlet in water tank, pin heat simultaneously, improve heat insulation effect.

Technical solution of the present utility model is: this is locked hot device and comprises outer valve cap, interior valve cap and piston, in interior valve cap piston is installed, the hot device of the whole formation lock of valve cap in installing in the valve cap outside; Valve cap is made up of internal valve box body, following air inlet cap in described, establish air admission hole at the top of internal valve box body, the air inlet cap of air admission hole under the bottom mounting strap of internal valve box body, piston is formed by cock cap is installed on the piston boit, piston is installed in the internal valve box body under spring is auxiliary, the piston cap of piston one end is sealed air admission hole, and piston boit stretches out air inlet cap down; Described outer valve cap is made up of outer valve cap body, last air exhaust loop, steam vent is set in the bottom of valve cap body outside, in the valve cap body, piston boit stretched out the following steam vent of outer valve cap body outside the last air exhaust loop of the top mounting strap upper air-vent of outer valve cap body, internal valve box body were installed under spring is auxiliary.

During installation, the hot device of lock is installed on the passage of solar water container; When the water tank external and internal pressure was in a basic balance, following steam vent was closed, and when the water in the water tank heats up and pressure increases when needing outside exhaust, connected the outside exhaust of steam vent up and down by valve cap in the tension jack-up of self; After gas was discharged, interior valve cap was closed steam vent up and down in the valve cap outside the auxiliary withdrawal down of spring, and draining can not continue outside distribute heat; During water, hot water flows out in water tank, and the space in the water tank increases and pressure reduces, and outside atmospheric pressure is the roof pressure piston downwards, and air admission hole is connected up and down, air inlet in water tank; When stopping water, internal and external pressure balance, piston is closed air admission hole up and down at the auxiliary retraction down of spring.

The hot device of lock of the present utility model is simple in structure, not only exhaust but also air inlet, and the lock hot mode is flexible, has reduced heat loss, has improved the thermal efficiency, high insulating effect.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: 1 internal valve box body, 2 times air inlet caps, air admission hole on 3,4 times air admission holes, 5,6 springs, 7 piston caps, 8 piston boits, 9 outer valve cap bodies, air exhaust loop on 10,11 times steam vents, 12 upper air-vents.

The specific embodiment

As shown in Figure 1, this is locked hot device and comprises outer valve cap, interior valve cap and piston, in interior valve cap piston is installed, the hot device of the whole formation lock of valve cap in installing in the valve cap outside; Valve cap is made up of internal valve box body 1, following air inlet cap 2 in described, establish air admission hole 3 at the top of internal valve box body 1, the air inlet cap 2 of air admission hole 4 under the bottom mounting strap of internal valve box body 1, piston is formed by piston cap 7 is installed on the piston boit 8, piston is installed in the internal valve box body 1 under spring 5 is assisted, the piston cap 7 of piston one end is sealed air admission hole 3, and piston boit 8 stretches out air inlet cap 2 down; Described outer valve cap is by outer valve cap body 9, last air exhaust loop 10 is formed, steam vent 11 is set in the bottom of valve cap body 9 outside, the last air exhaust loop 10 of the top mounting strap upper air-vent 12 of outer valve cap body 9, in the valve cap body 9, piston boit 8 stretched out the following steam vent 11 of outer valve cap body 9 outside internal valve box body 1 was installed under spring 6 is assisted.

During installation, the hot device of lock is installed on the passage of solar water container; When the water tank external and internal pressure was in a basic balance, following steam vent 11 was closed, and when the water in the water tank heats up and pressure increases when needing outside exhaust, connected steam vent 12,11 outside exhausts up and down by valve cap in the tension jack-up of self; After gas was discharged, interior valve cap was closed steam vent 12,11 up and down in the valve cap outside spring 6 auxiliary withdrawals down, and draining can not continue outside distribute heat; During water, hot water flows out in water tank, and the space in the water tank increases and pressure reduces, and outside atmospheric pressure is the roof pressure piston downwards, and air admission hole 3,4 is connected up and down, air inlet in water tank; When stopping water, internal and external pressure balance, piston is closed air admission hole 3,4 up and down at spring 5 auxiliary retractions down.
