Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of poor safety of the existing pressure tank, and provide a pressure tank used in the water purification system. When the water in the pressure tank is filled up to generate water injection pressure, the pressure limiting valve closes the water inlet. In this way, the pressure in the barrel is limited to continue to increase, and the pressure barrel is prevented from bursting; when the external pressure of water injection is removed, the pressure limiting valve automatically opens and becomes normally open

Embodiment 1

[0024] Such as Figures 1 to 4 The shown pressure barrel used in the water purification system includes a pressure barrel body 1, a pressure limiting valve installation groove 10 is provided on the top of the pressure barrel body 1, and a pressure limiting valve installation groove 10 is opened for water to enter the barrel. Inside the inlet and outlet 11, the pressure limiting valve 2 is packed into the pressure limiting valve installation groove 10 and the pipe at the output end stretches into the inlet and outlet 11. Wherein the pressure limiting valve 2 is a normally open valve that can automatically close and cut off the water injection when exceeding a certain injection water pressure threshold, and automatically open the water outlet when it is lower than the threshold. Its specific structure is as follows:

[0025] The pressure limiting valve 2 includes a valve seat 20 , a ball valve spool 234 and a piston assembly 23 for driving the ball valve spool to rotate. The v...

Embodiment 2

[0031] Such as Figure 4 As shown, the difference between this embodiment and embodiment 1 is that a stud is provided in the middle of the output surface of the piston 230, and an external helical thread is provided on the stud. The other end of the valve stem 231 is provided with an inner screw hole matching with the stud; the matching relationship is just opposite to that of the first embodiment.

Abstract

The invention relates to household water purifying equipment, in particular to a pressure barrel for a water purifying system. The pressure barrel for the water purifying system comprises a pressure barrel body; an access port for feeding water in the barrel is formed in the top end of the pressure barrel body, and is provided with a pressure limiting valve for preventing excessive pressure; and the pressure limiting valve can automatically cut off the water injection when exceeding a certain water injection pressure threshold, and can automatically open a normally open valve for discharging water when being lower than the threshold. When the water is fully filled in the pressure barrel to generate the water injection pressure, the pressure limiting valve closes a water inlet to limit continuous increment of the pressure in the barrel to prevent burst of the pressure barrel; and when the water injection pressure is relieved, the pressure limiting valve automatically opens to become normally open.

Description

technical field [0001] The invention relates to household water purification equipment, in particular to a pressure barrel used in a water purification system. Background technique [0002] Pressure barrels are mainly used to store water in household water purification systems, and generally bear high pressure. With the fierce competition, the price of pressure barrels has dropped, and plastic barrels have continued to replace steel barrels. In the existing market, in order to save costs, the plastic wall of the plastic pressure barrel is made relatively thin. Due to the influence of the manufacturing process and the overload of water storage, the plastic pressure tank will gradually expand. Every year, there will be plastic pressure tanks that are difficult to withstand pressure and cause explosions, causing danger to the home kitchen and causing huge compensation losses for the manufacturer. Contents of the invention [0003] The purpose of the present invention is to ...
