Embodiment Construction

[0022] Such as Figure 1 to Figure 3 As shown, a joint is mainly composed of a body, a piston 1, a bracket 2, a prestressed spring 3 and a prestressed screw 4, and the piston includes a piston head and a piston rod. The direction of the piston head is sunken in the first adjusting hole, the adjusting hole is provided with an internal thread matching the external thread of the prestressing screw, and a second adjusting hole is provided on the wall of the piston head away from the piston rod.

[0023] The joint also includes a closing spring 5 and a regulating valve 6; the inner wall of the body is provided with an inwardly protruding boss coaxial with the body around the inner wall of the body, and a ring and the external thread of the outer wall of the bracket are arranged on the inner wall of the boss Matching internal thread, on the edge of the boss facing the water inlet end, a circle of flange protruding inward is provided to prevent the bracket from sliding out of the val...

Abstract

The invention provides a connector which is mainly composed of a body, a piston, a support, a prestress spring and a prestress screw. The connector is internally provided with a closed spring and an adjusting valve. When the water inflow is adjusted from the water outlet end, the adjusting valve drives the piston to move towards the water outlet end under the influence of the water pressure, the tension of the closed spring is lowered, the prestress spring is compressed, and a piston head is pulled into a water inlet hole of a water inlet valve to block the water inlet hole, so that water cannot flow outwards; after adjustment is conducted, a faucet is screwed to the connector from the water outlet end, the connector moves towards the water inlet end along with the faucet, and the adjusting valve and the piston can be pushed to move towards the water inlet end; the closed spring is pressed towards the support, the adjusting valve returns to the position generated before adjusting is conducted, the distance between the piston head and a water outlet hole of a water outlet valve is changed, that is, the water pressure required for pushing the piston head into the water outlet hole of the water outlet valve is changed, the water yield is achieved from the water outlet end, and the connector can cut off water flow automatically in the adjusting process.

Description

technical field [0001] The invention relates to a joint used for connecting water pipes, in particular to a joint capable of adjusting the water output from a water outlet, which belongs to the optimization technology of the joint. Background technique [0002] The connection between the water pipes and the connection between the water pipe and the faucet are all realized through joints. There are generally two ways to supply water to buildings, one is to use a booster pump to send water from bottom to top, and the other is to install a water tank on the roof and use the water level difference to send water from top to bottom. No matter what kind of water delivery method is used, the water pressure of different floors will be different, which will lead to different water output on different floors. Therefore, there are now some joint designs with balanced water flow, aiming to make the water flow of different floors tend to be the same. [0003] A joint is disclosed in the...
