Technical Field
[0001] The utility model relates to the technical field of lead-free angle valves, in particular to a lead-free angle valve for water supply and drainage. Background Art
[0002] Lead-free angle valve is a valve used to control the flow of liquid. Compared with traditional angle valves, lead-free angle valves do not contain harmful lead materials, which is more environmentally friendly and healthy. Lead is a toxic heavy metal that can cause serious harm to human health under long-term contact, especially potential harm to children's neurological development and intellectual development. Therefore, lead-free angle valves have become a safer and more environmentally friendly choice. The function of lead-free angle valves is to adjust the opening and closing degree of the valve by rotating the valve handle or operating rod, thereby controlling the flow and pressure of the fluid. This valve is widely used in water supply pipe systems in homes, industries and commercial buildings. In family residences, lead-free angle valves are often used in faucets, wash basins, showers, kitchens and bathrooms to control the flow and switch of water. Especially when there are infants and young children in the family, the use of lead-free angle valves can better protect the health of children. In addition, lead-free angle valves can also be used in toilets, wash basins, sprinkler systems and other places in commercial buildings to control water flow. Commercial places usually have large water flow requirements, and the high-efficiency performance of lead-free angle valves can meet these needs. In the industrial field, lead-free angle valves are also widely used. For example, it can be used in the cooling system of the factory to adjust the flow and temperature of the coolant by controlling the opening and closing of the valve to ensure the normal operation of the equipment. In addition, in the hydraulic control of processing equipment, the lead-free angle valve can accurately control the flow and pressure of the liquid as needed to improve production efficiency. The use of lead-free angle valves not only ensures the safety and quality of water use, but also helps to reduce pollution to the environment and protect human health. With the continuous improvement of awareness of environmental protection and health, lead-free angle valves will be more widely used. In addition to its environmental protection and health advantages, lead-free angle valves also have some other characteristics. First, lead-free angle valves usually have a long service life and can withstand high pressure and high temperature environments. Secondly, lead-free angle valves have a compact structure and are easy to install. Valves of different sizes and connection methods can be selected according to different pipeline requirements. In addition, lead-free angle valves also have lower maintenance costs because they rarely need to be repaired or replaced. In general, lead-free angle valves are environmentally friendly, healthy, reliable and versatile valves that are suitable for various pipeline systems in homes, industries and commercial buildings. By using lead-free angle valves, we can ensure the safety and quality of water use, reduce pollution to the environment and protect human health. With the increasing awareness of environmental protection, lead-free angle valves will become the mainstream choice for future piping systems.
[0003] However, the existing lead-free angle valve usually has liquid flowing out of the water outlet at the moment of opening, and the rate of liquid passing through the water outlet increases linearly during the process of the angle valve gradually opening completely. Chinese patent CN 213929456 U proposes a flexible lead-free bathroom angle valve with a changeable connection position, the structure of which includes a valve body, an opening and closing cavity arranged in the valve body, and a water outlet joint arranged on the right side wall of the valve body. The water outlet joint is connected to the opening and closing cavity, and an opening and closing part is arranged in the opening and closing cavity. A valve stem is arranged at the center of the upper surface of the opening and closing part, and the upper end of the valve stem passes upward to the outside of the valve body and is provided with a hand wheel. A telescopic hole is arranged on the lower surface of the valve body, and a lifting seat is arranged below the valve body to fit its lower surface. A telescopic column matching the telescopic hole is arranged at the center of the upper surface of the lifting seat, and symmetrical limit grooves are arranged on the inner walls on the left and right sides of the telescopic hole, and the limit grooves are in the shape of strips. Limit blocks matching the limit grooves are arranged on the left and right sides of the upper end of the telescopic column. A water inlet hole is arranged at the center of the lower surface of the lifting seat, and the upper end opening of the water inlet hole is located at the center of the upper end surface of the telescopic column. The water inlet is connected to the opening and closing chamber through the water through hole. The diameter of the water through hole is smaller than the diameter of the opening and closing chamber, and a sealing step is formed between the water through hole and the opening and closing chamber, and the lower surface of the opening and closing part fits with the sealing step. A limit head is screwed to the lower end of the water inlet. An annular notch is provided on the outer wall of the lower end of the lifting seat, and an annular adjustment groove is formed between the notch and the limit head. An angle adjustment device matching it is provided in the adjustment groove. A water pipe is provided on the left side of the angle adjustment device. A water inlet joint connected to it is provided on the lower surface of the left end of the water pipe. However, this angle valve cannot instantly open the water outlet to the maximum rate, and liquid will flow out from the water outlet joint at the moment of opening. This existing angle valve structure is not applicable in some occasions where water discharge needs to be delayed to improve drainage safety, certain chemical experiments or rapid flushing systems need to instantly release a large amount of liquid to ensure the rapid response or flushing effect of the system.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 A lead-free angle valve for water supply and drainage comprises a valve core housing 1, a valve stem 2, a valve cover 3, a fixed baffle 4, and a rotating baffle 5. The fixed baffle 4 is fixedly installed in the valve core housing 1, and a fan-shaped notch is provided on the fixed baffle 4. The valve cover 3 is coaxially fixedly installed on the valve core housing 1, and the valve stem 2 is coaxially rotatably installed on the valve cover 3. The rotating baffle 5 is fixedly installed at the bottom of the valve stem 2. The rotating baffle 5 is as shown in FIG. Fig.10 As shown, the fixed baffle 4 is divided into an upper baffle and a lower baffle, a cavity is left between the upper baffle and the lower baffle, a rotating baffle 5 is arranged in the cavity, and the upper and lower end surfaces of the rotating baffle 5 are in contact with the upper baffle and the lower baffle, a water outlet cavity 6 is arranged between the fixed baffle 4 and the valve cover 3, and an annular notch 7 is opened on the valve core shell 1, as shown in FIG. Fig. 9 and Figure 8 As shown, the height of the annular notch 7 is higher than the installation height of the fixed baffle 4. Figure 5As shown, an annular groove 8 is fixedly arranged on the outside of the valve core shell 1, an elastic module 9 is installed at one end of the annular groove 8, and an elastic water bag 10 is arranged at the other end of the annular groove 8. By adjusting the design parameters of the elastic water bag 10, such as capacity and elasticity, the flow of the angle valve can be controlled. By increasing or decreasing the capacity of the elastic water bag 10, the flow size of the angle valve can be adjusted to achieve the flow control function of the angle valve. A water pipe 11 is connected to the elastic water bag 10, and the water pipe 11 runs through the valve core shell 1 and is connected to the water outlet chamber 6. A water baffle 12 is also slidably installed on the annular groove 8. The design of the water baffle 12 enables the angle valve to have a controllable water flow opening and closing function. When the angle valve is opened, the water flow can pass freely; when the angle valve is closed, the water flow is completely blocked. The movement of the water baffle 12 is affected by the elastic module 9 and the elastic water bag 10. By adjusting the design parameters of the two, the flow regulation and water flow control of the angle valve can be achieved. One end of the water baffle plate 12 is fixedly connected to the elastic module 9 , and the other end of the water baffle plate 12 is fixedly connected to the elastic water bag 10 . The water baffle plate 12 covers the annular notch 7 , and a water inlet 14 is also provided at the bottom of the valve core housing 1 . When using the angle valve, first rotate the valve stem 2.

The elastic water bag 10 is made of food-grade silicone material.
[0032] Working principle: When using the angle valve, first rotate the valve stem 2. When the rotating baffle 5 rotates to coincide with the fixed baffle 4, the water outlet chamber 6 opens. When the water outlet chamber 6 is completely filled with liquid and the internal hydraulic pressure reaches the elastic limit of the elastic water bag 10, the liquid inside the elastic water bag 10 pushes the elastic water bag 10 to expand instantly along the annular groove 8. After the elastic water bag 10 expands, it will lift the water baffle 12 to make the water baffle 12 slide along the annular groove 8 and open the annular notch 7 to drain the angle valve. When the valve stem 2 is rotated in the opposite direction, the rotating baffle 5 will block the fan-shaped notch left by the fixed baffle 4, the water outlet chamber 6 is no longer filled with water, the internal hydraulic pressure is reduced, the hydraulic pressure in the elastic water bag 10 is reduced, and the elastic water bag 10 shrinks. At this time, the elastic module 9 connected to the other end of the water baffle 12 will be reset, and the water baffle 12 will be pushed to reset it. The elastic water bag 10 is compressed, the annular notch 7 is closed, and the entire angle valve is closed.
