Description

Faucet spout with constant flow device

technical field

The invention relates to a faucet spout with a constant flow device which allows users to independently adjust the water output of the faucet according to needs, and belongs to the water-saving technology of tap water supply systems.

Background technique

Most of the existing faucets are equipped with a bubbler at the water outlet, and the installation of the bubbler is installed through a sheath and the water outlet of the faucet. The function of the bubbler is to generate negative pressure when the water flows to suck in the air and mix it with the water, so as to strengthen the impact force of the water. It has been widely used now, but it has the following disadvantages: there is no constant flow control device, and people are often used to opening it in use, so it is often difficult to achieve effective control through the valve of the faucet.

There are generally two ways to supply water to buildings at present, one is to use a booster pump to send water from bottom to top, and the other is to place a water tank on the roof and use the water level difference to transport water from top to bottom. Regardless of the water delivery method, the water pressure on different floors will be different, resulting in different water output on different floors.

In daily life, the washing faucet is the most frequently used and used in the largest amount, and the ideal state of the washing faucet can be summarized in the following three points: first, it covers a large area, second, it has a strong flushing force, and third, it has less water output.

Therefore, it is necessary to find a faucet spout that the user can independently adjust and set a suitable water output according to the actual water pressure and flow conditions.

Detailed ways

As shown in Figure 1, the faucet spout with a constant flow device is mainly installed on the faucet outlet for use, and it is mainly composed of a connection sleeve 1 and a constant flow device 2, and the constant flow device 2 is placed in the connection sleeve 1 , the connection sleeve 1 and the faucet outlet are provided with matching threads; when installing, put the gasket 3 on the faucet outlet, and then screw the connection sleeve 1 on the faucet outlet.

As shown in Figures 2 and 3, the constant flow device 2 is composed of a housing 21, a valve body 22, a tower spring 23, a valve core 24, a filter element holder 25, and a filter element 26; the housing 21 is barrel-shaped, One end is open and the other end is closed. The closed end is provided with a water outlet. The outer edge of the open end of the shell 21 is provided with a flange 211. The inner wall of the connecting sleeve 1 is provided with a bayonet matching the flange. The shell 21 is positioned on the connecting sleeve through the flange 211. 1 on the bayonet on the inner wall.

The inner wall of the opening end of the casing 21 is provided with an annular slot, and the outer wall of the filter element holder 25 without the bracket is provided with a protrusion matching the annular slot on the casing 21, and the filter element holder 25 is positioned on the casing 21 through the protrusion. the inner wall.

The center of the valve core 24 is provided with a pressure relief hole, and the shape of the pressure relief hole adopts a cross shape or a hexagonal shape. The position of the spool 24 on the tower spring 23 is adjusted by a cross wrench or an inner hexagonal wrench, so as to achieve the purpose of adjusting and setting the flow rate of the faucet.

A part of the spool 24 is a cylinder, and the other part is a conical body with one end face of the cylinder as the bottom surface. External threads are provided on the outer edge of the cylinder part of the spool 24, and the spool 24 One end of the cone is put into the tower spring 23 from the tower top of the tower spring 23, and a radial force is applied to the cylinder end of the spool 24 towards the tower spring 23, so that the spool 24 enters the tower shaped spring 23, the more the spool 24 enters the tower spring 23, the easier it is for the water flow to overcome the elastic force of the tower spring 23 and push the spool 24 to the valve body 22.

When the water flows, the water flow driving force acts on the end face of one end of the valve core 24 cylinder. When the water flow driving force is less than the prestress of the tower spring 23, the valve core 24 maintains the status quo; when the water flow driving force is smaller than the tower spring 23 When the prestress of the valve core 24 maintains the status quo, the valve core moves toward the valve body 22; when the tapered platform part of the valve core 24 completely enters the tapered hole on the valve body 22, at this time, the water flows through the pressure relief hole. , so as to prevent the phenomenon of stuffy blockage. After closing the faucet, the driving force of the water flow disappears, and under the action of the tower spring, the spool 24 will automatically return to the initial state.

The distance the spool moves depends on the size of the driving force of the water flow. The movement of the spool 24 changes the distance between it and the valve body 22, thereby changing the size of the water flow channel. Therefore, the purpose of controlling the flow can be achieved by adjusting and controlling the position of the spool on the tower spring.

Described valve body 22 is the hollow cylinder that one end is open and the other end bottom is provided with tapered opening; Valve body 22 is put into shell 21, makes the open end of valve body 22 towards the closed end of shell 21; Spring 23 is screwed on the screw thread of spool 24 outer walls, then tower spring 23 and spool are put into shell 1 together and be arranged on valve body 22, make the tower bottom of tower spring 23 be placed on valve body 22.

The tapered opening at the bottom of the valve body 22 has the top of the cone facing the open end.

The diameter of the outlet hole on the closed end of the shell 21 is 0.3 mm to 0.6 mm.

The closed end of the casing 21 is an outwardly curved arch, which increases the coverage area of the water outlet from the faucet.

The filter element support 25 is a hollow cylinder with openings at both ends, and a support is provided at one end towards the valve body 22; the filter element support 25 is put into the casing 21 and is positioned at the top of the valve core 24, and then the filter element 26 is arranged on the filter element support 25 on the bracket inside. In order to prevent impurities in the water from blocking the outlet hole, the constant flow device 2 is provided with a filter element 26 , the filter element 26 is fixed by the filter element support 25 , and the water flowing through the filter element support 25 flows to the valve body 22 .

The application of the faucet spout with a constant flow device does not require major modifications to the original water supply system, just unscrew the faucet and replace the bubbler on the faucet with the faucet spout with a constant flow device. Some investment will not be wasted, and the installation is simple, the input cost is relatively low, and it has positive significance for environmental protection and water conservation.

In practical applications, the residents of a building are equipped with faucet spouts with constant flow devices. If the water storage tank is installed on the roof, the water pressure and water output of low-level users will be effectively controlled, so that high-level users The water outlet pressure has been improved, so that the water pressure of users on different floors tends to be balanced, and the water output tends to be consistent.

The invention can also be popularized and applied to the field of liquid and gas that need to control flow.

The above-mentioned embodiments are only used to illustrate and explain the purpose of the present invention, rather than to limit the present invention. Those of ordinary skill in the art may make various changes or substitutions within the essential scope of the present invention, which shall also belong to the present invention. scope of protection for inventions.
