Running water valve with water-saving function

Abstract

The invention relates to the water supply and drainage technical field, in particular to a running water valve with the water-saving function. The running water valve comprises a torsion bar, a spring, a spring cavity, a top screw thread, a middle screw thread, a bottom screw thread, a torsion bar screw thread, a water outlet pipe, a torsion bar through-hole, a sealing ring, an overflow cavity, a conical valve, a feedwater pipeline, a sleeve and a snap ring, wherein the top screw thread, middle screw thread and bottom screw thread with the same vertical length and thread turns are arranged on the side wall of the torsion bar through-hole from top to bottom; and the side wall of the torsion bar is provided with the annular snap ring which is integrated with the torsion bar and also provided with the torsion bar screw thread which fits with the top screw thread, the middle screw thread and the bottom screw thread respectively. By using the running water valve, when the water user does not satisfy a lower flow velocity of water, the direction of the applied force and the operation mode are needed to change so as to increase the flow rate. Therefore, the invention has remarkable water-saving effect.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage, in particular to a tap water valve with a water-saving function. Background technique [0002] The flow control of taps is an important part of water-saving projects. The valve sensitivity of existing water faucets is usually low, and twisting the handle of the faucet is a very convenient and repetitive operation method. Due to excessive torque or habitual operation, water users are very easy to turn the valve unconsciously. Open to exceed its required displacement, so that the water flow rate of the faucet is often greater than the water flow rate required by the water user, resulting in a waste of water resources. However, in the prior art, there is no measure to effectively control the initial opening degree of the faucet valve and the method of increasing the water flow velocity. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the ...

Problems solved by technology

The valve sensitivity of existing water faucets is usually low, and twisting the handle of the faucet is a very convenient and repetitive operation method. Due to excessive torque or habitual operation, water users are very easy to turn the valve unconsciously. Open to exceed its required displacement, so that the water flow rate of the faucet is often greater than the water flow rate required by the water user, resulting in a waste of water resources

However, the prior art does not have measures to effectively control the initial opening degree of the faucet valve and the method of increasing the water flow velocity.
