Embodiment Construction

[0010] Depend on figure 1 It can be seen that the apron (4) is set on the entrance tile (1), and the apron (7) is embedded on the piston (6); the spring (8) presses the piston (6) and pushes the piston connecting rod (5) to move the tile (2) To the bottom, the water channel is opened; the cavity at the lower end of the piston (6) is provided with a feedback hole (9) connected to the outlet of the constant pressure limiting valve, and as the pressure at the outlet of the constant pressure limiting valve increases, water flows through the feedback hole (9) On the piston (6), the spring (8) is compressed, the tile (2) is pulled up by the piston connecting rod (5), the water channel becomes smaller, and when the piston (6) is pushed to the top, the tile (2) Pulled up by the piston connecting rod (5), the tile (2) blocks the water channel. The rubber ring (4) is used to seal the water, the tile (1) and the tile (3) are fixed, the tile (2) moves to open or close the water channel, ...

Abstract

The invention discloses a constant pressure valve, which is mainly composed of a porcelain (1), a porcelain (2), a porcelain (3), a rubber ring (4), a piston connecting rod (5), a piston (6), a rubber ring (7), a spring (8), a feedback hole (9) and a housing (10). The constant pressure valve of the invention is installed on tap water pipe to limit high tap water pressure, thereby achieving low-pressure constant output and effectively prolonging the service life of protective water pipes, water bladders and appliances.

Description

technical field [0001] The invention relates to a water passage device, in particular to a constant-pressure pressure-limiting valve. Background technique [0002] In reality, the pressure of tap water varies from region to region, and users can only accept it passively and cannot control it. When the water pressure is high, it will cause damage to water pipes, containers, and utensils. If it can be controlled at a pressure value that satisfies the use and is not high, the service life of the water tank of the electric water heater, the leather plug of the toilet tank for flushing the toilet, and the automatic opening and closing of the faucet, etc. will be greatly extended. Contents of the invention [0003] The object of the present invention is to avoid the above disadvantages and provide a constant pressure valve with low price and long service life, good use effect and maintenance-free. [0004] In order to achieve the above object, the present invention adopts the ...
