The rubber can be molded at one time, and there is no air or water leakage; the installation is simple, and no pressure relief valve is required, which reduces the installation cost and difficulty.

Description

A low-cost pressurized heat preservation water tank

technical field

The utility model relates to a thermal insulation water tank, in particular to a low-cost pressure-bearing thermal insulation water tank used in the field of air conditioning. the

Background technique

With the increasing awareness of environmental protection in the whole society, more and more hotels, schools, and families are using air-energy heat pump water heaters to generate shower water. For small power systems, pressure-bearing heat preservation water tanks are generally used. the

The pressure-bearing heat preservation water tanks currently on the market generally use stainless steel as the inner tank, because stainless steel must not only be formed into a barrel shape, but also the bottom and top must be well welded into a sealed pressure-bearing tank. For a long time, it may break and cause water leakage and other phenomena. Valves are installed at the water inlet and outlet, which may also cause hidden dangers of water leakage. Therefore, the water tank with this structure will inevitably have problems such as high material cost, difficult processing, and short life. And dealer promotion and service bring a lot of trouble. the

Utility model content

The technical problem to be solved by the utility model is to provide a pressure-insulated water tank with low cost and no water leakage. the

In order to solve the above-mentioned technical problems, the utility model is realized through the following technical solutions: a low-cost pressure-bearing thermal insulation water tank, the inner tank layer is made of high-temperature-resistant rubber material, and the water inlet and outlet are integrally formed with the inner tank. Therefore, the one-time forming of rubber and its own elastic characteristics are used to completely solve the problems of difficult processing, poor sealing, and water leakage of the stainless steel liner. the

The utility model has the following technical characteristics: 1. Low cost, using rubber instead of stainless steel, which saves a lot of material cost; 2. Simple process, low cost, rubber can be formed by a mold at one time, and there is no air or water leakage; 3. The installation is simple. The water inlet and outlet used in this design are all rubber water pipes formed with the inner tank at one time. Therefore, when the user installs, the water inlet and outlet pipes can be directly connected to the water inlet and outlet pipes by using the tightness of the rubber. Tap water pipe connection, installation and maintenance are very easy, and ordinary users can handle it without professional tools; 4. No need for a pressure relief valve, because the stretching elasticity of rubber is much greater than that of stainless steel, so the corresponding expansion can be released through the rubber and the insulation foam around it , so that there is no need to consider water leakage or water tank bursting caused by expansion, and there is no need to install a special pressure reducing valve, which reduces the installation cost and difficulty. the
