Abstract

The utility model discloses an all-plastic water tank for a vacuum-tube water heater. A water tank inner liner 2 is made of non-toxic and tasteless plastic. Stiffening ribs are uniformly distributed on the tank body of the inner liner 2, the two end faces of the inner liner 2 and the two end faces of an outer housing 4 are all provided with stiffening surfaces, the tank body adjacent to the two end faces of the outer housing 4 are provided with stiffening rings. The utility model has the advantages of good sealing performance, no pollution of water quality, easy cleaning, high water pressure bearing, high heat efficiency, good heat insulating property, low cost, portable handling, and easy and simple operation and installation; moreover, the volume of the utility model is larger than an ordinary water tank.

Description

The overall plastic solar vacuum tube water heater water tank

The utility model relates to a kind of gold and moulds solar energy vacuum tube water heater water tank.

Existing solar energy vacuum tube water heater water tank, its inner bag is to adopt sheet metal to be formed by connecting through welding, withholding, and pipeline and inner bag casing are by welding, are threaded and bonding forming poor sealing, weld seam is understood corrosion and is influenced water quality, and whole box body is a level and smooth cylinder; Its blast pipe is installed near the top, generally apart from the about 10mm of tank top, is unfavorable for ensureing that water tank is full of entirely, its heat supply water and to advance cold water be a pipeline, and hot water is used to a certain degree will adjust valve, wait for that cold water fills, thereby operate more complicated; Tank shell adopts stamping forming two ends and the riveted joint of metal sheet roll bending or screw to be formed by connecting, and the time one is long, is easy to form crackle in the junction; Vacuum tube connecting hole on inner water tank and the shell adopts the punch forming location also relatively more difficult, makes and the assembling process relative complex; Simultaneously, the water tank of making of metal exists also that volume is little, not high, the imperfect problem of heat-insulating property of the thermal efficiency.

The purpose of this utility model is that a kind of overall plastic solar vacuum tube water heater water tank will be provided, and the good airproof performance of this water tank can not influence water quality, clean easily, blowdown, volume is big, can bear higher hydraulic pressure, thermal efficiency height, and is simple to operate, and assembling easily, and heat-insulating property is good.

The purpose of this utility model is achieved in that by inner water tank 2, blast pipe 1, heat-insulation layer 3, the solar energy vacuum tube water heater water tank that tank shell 4 is formed, the circular vacuum tube connecting hole that matches each other is respectively arranged on inner water tank 2 and tank shell 4, it is characterized in that: inner water tank 2 is an integral body, its casing is a cylinder, the center of the groove both ends of the surface 7 of several indents parallel with axis that evenly distribute on cylindrical cylinder is domes, it around the dome petal of projection, blow-off pipe 8 is positioned at the bottom of inner water tank 2, the lower wall level of its tube wall and inner water tank 2, blast pipe 1 is positioned at inner water tank 2 tops, the upper wall level of its tube wall and inner water tank 2, heat supply water pipe 5 advances cold water pipe 6 and is positioned at heat supply water pipe 5 bottoms near inner water tank 2 tops; Tank shell 4 is an integral body, and its casing is a cylinder, and the center of both ends of the surface 9 is that recessed circle, recessed circle outside are the petals of uniform projection around the annulus, annulus of a projection, near the annulus of two ends each oriented outer lug of tank surface of tank shell 4.

The utility model is owing to be that raw material is made complete inner water tank with extrusioning-blow technology, with nontoxic, tasteless plastics, can effectively improve water quality, and the groove of the uniform indent parallel with axis of inner water tank casing is a reinforcement, the lobed petal in two ends is a reinforcement face, thus can avoid leaking, the problem of burn into comprehensive mechanical performance difference; Its blow-off pipe, blast pipe, the heat supply water pipe, advance cold water pipe and inner water tank is connected as a single entity, blow-off pipe is positioned at the bottom of inner water tank, the lower wall level of its tube wall and inner water tank, the water of water tank can be discharged fully, be convenient to clean water tank and blowdown, blast pipe is positioned at inner water tank top, its tube wall and inner water tank upper wall level, water tank is full of entirely, and can reduce the pressure of water tank, be applicable to the siphon off water mode of big capacity tank, owing to adopt the heat supply water pipe and advance cold water pipe and separate, so also can adopt the natural circulation mode water intaking, and heat supply water and advance cold water and can carry out simultaneously, easy and simple to handle; In addition, the also lobed petal of the both ends of the surface of tank shell is a reinforcement face.During assembling, two from an end are cut between the annulus of outer lug, inner bag is packed into, again a termination of downcutting is fastened on the tank box of incision, connect like this, make the water tank assembly manipulation simple, convenient and easy, and firmly degree improves greatly, is convenient to fix, locatees, seals, and heat-insulating property might as well; Simultaneously, this water tank all made of plastic capacity can big twice be many than the capacity of general water tank, and the vacuum tube connecting hole on inner water tank and the shell is made the location than being easier to, 16 vacuum tube connecting holes can be arranged, thereby, this water tank thermal efficiency height, good heat insulating, with low cost, transportation install light easily.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is an installation diagram of the present utility model.

Fig. 2 is the rearview of the utility model inner water tank.
