Description

Reinforcement of the pressure tank of the joint unit

technical field

The invention relates to a pressure barrel, in particular to a pressure barrel capable of strengthening joint units. the

Background technique

At present, pressure vessels are widely used in piping systems, such as pressure accumulation, water storage and water hammer absorption in hydraulic piping systems, and absorption expansion in heat exchange systems. , and water storage for reverse osmosis drinking water systems. the

Generally, the inner compartment of the pressure tank has a pressurized chamber and a water storage chamber. The structure of the existing water storage chamber has various forms and the design has become mature, such as the bladder type, single-diaphragm type type), double-diaphragms type, and single-diaphragm plus a polypropylene (referred to as PP, polypropylene) liner barrels and other types, the various types of pressure barrels mentioned above, please refer to the patent documents China Taiwan M312357, China Taiwan 263054 , US4351363, US4784181, China Taiwan 250911, US7363944, etc. the

All kinds of pressure barrels have an outer barrel and a joint fixed on the outer barrel. The joint is used to connect the water storage chamber and the external piping, so the strength of the joint is one of the key factors that determine the life of the pressure barrel, as shown in the figure 1 (disclosed in the patent document DE4223380C1 case), a typical pipeline configuration diagram, the pressure tank 1 is fixed to the pipeline 2 with a joint (not shown) in an upside-down manner. It is conceivable that the joint bears a static load (static loading) and dynamic loading (dynamic loading), the static load comes from the weight of the pressure tank 1 and its water storage, the dynamic load comes from the vibration transmitted from the pump 3 to the pressure tank 1 through the pipeline 2, and the rapid entry and exit of the pressure tank 1 Vibration caused by water. These loads will accelerate joint damage. the

In addition, large-capacity water storage pressure tanks are often placed horizontally, and the joints are easily damaged by transverse shear force during assembly and transportation. the

In the existing technology, no one has been found to improve this problem. Only in the patent case of M312357 in Taiwan, China, the improvement of the bonding structure between a compression bag and a barrel body is disclosed. As shown in Figure 2, the pressure barrel A compression bag 5 is provided inside a barrel body 4. The barrel body 4 is provided with a through hole 401 and an air delivery hole 402 for pouring pressure gas into the barrel body 4. The compression bag 5 corresponds to the through hole 401 is provided with an assembly part 501, the assembly part 501 is integrally covered with a rigid reinforcing plate 6 and a water connector 7, one end of the water connector 7 is combined and fixed with the reinforcing plate 6, and passes through the assembly part 501 to pass through the compression bag 5 , and the other end passes through the through hole 401 . The assembly part 501 supporting the compression bag 5 by the reinforcing plate 6 is attached to the inner side of the barrel body 4, so that the assembly part 501 and the periphery of the through hole 401 can form an airtight effect to prevent pressure gas from leaking out. Therefore, the pressure barrel shown in Figure 2 is only to solve the fit and tightness of the compression bag 5 and the barrel body 4, but still does not further improve the bonding strength between the water connector 7 and the barrel body 4, that is to say, The bonding area between the water joint 7 and the barrel body 4 is small, and there is still a doubt that the strength is insufficient. the

This shows that above-mentioned existing pressure barrel obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved. In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. urgent problem to be solved.
