Regulating valve is a fluid control device, it can control fluid flow, pressure, temperature and other parameters, in order to achieve the purpose of regulating fluid flow characteristics. It is composed of a piston or ball spool, in which there is a manual or electric mechanism with adjustment function, it can control the position of the piston or ball spool, so as to change the pressure and flow rate in the valve, so as to adjust the flow characteristics of the fluid.
The main function of the regulating valve is to adjust the flow rate, pressure and temperature, so that the fluid flow characteristics are more stable, so as to improve the efficiency of the fluid. It can regulate the flow of fluid to keep it at a low level, thus saving energy; The pressure of the fluid can also be adjusted to keep it at a low level, thus reducing noise in the piping system; The temperature of the fluid can also be adjusted to keep it at a low level, thus preventing condensation in the piping system, etc.

Ten considerations for buying solid wood furniture
Solid wood furniture, comprehensive wood furniture, and all-solid-wood furniture are collectively referred to as **solid wood furniture**.
1. **Wooden Furniture**: This type of furniture is mainly made from wood materials such as solid wood or artificial boards, except for decorative parts and accessories.
2. **Solid Wood Furniture**: It is constructed using solid wood boards or sawn wood as the base material, with a finished surface. Alternatively, it may be coated with solid wood veneer or wood veneer before being painted. Solid wood panels are created through secondary processing like jointing or integrated wood.
3. **Comprehensive Wood Furniture**: This includes furniture made from a combination of solid wood, artificial boards, and other materials.
When purchasing solid wood furniture, there are several important points to consider:
1. According to national regulations, the wood used in general solid wood furniture must be properly dried, with a moisture content below 12%. The use of wood that is still infested by insects is strictly prohibited. Additionally, the surface and storage areas should not contain resin capsules. To check if the moisture content is under 12%, you can place a piece of wood on your palm for 10 seconds. If it feels dry, it is likely to meet the requirement. A heavier piece of wood usually indicates better quality.
2. The function of the furniture should match your family’s needs, and its size should fit the available space. For example, the middle headroom height of a writing desk should be over 580 mm, the width of the middle headroom should be more than 520 mm, and the seat height of a chair should be around 420 or 440 mm.
3. All artificial board components should have edge banding, and all hardware should be fully installed without missing screws or nails. Choosing furniture without edge banding may indicate poor environmental protection performance.
4. The structure of solid wood furniture should be firm, with no loose joints or broken tenons. Avoid buying "thirty-one furniture" (a term referring to low-quality furniture made with particleboard, nails, and paint) or "three-no drawers" (drawers with no grooves, plugs, or bottoms).
5. The surface of panels, such as doors or countertops, should be smooth and free of obvious warping. For panels with a diagonal length of at least 1400 mm, the allowable warping should not exceed 3 mm.
6. Solid wood furniture must be stable and complete. When opening cabinet doors 90 degrees, the cabinet should not tilt forward when gently pulled. Glass doors should be edged and treated, and mirrors should be securely fixed with beads.
7. Cabinet doors and drawers should open and close smoothly. When a drawer is pulled out two-thirds, the sag should not exceed 20 mm, and the left-to-right swing should be less than 15 mm.
8. If the panel is covered with thin wood or other materials, it should be tightly and smoothly applied, with no glue penetration, delamination, or bubbling.
9. The paint on the surface of solid wood furniture should be even and glossy, with consistent color across the unit or set. Paint should not be cracked, sticky, or dripping. Internal surfaces and other painted areas should remain clean.
10. After purchasing, proper maintenance is essential. Avoid bumping or scratching during handling. Level the cabinet before loading clothes to ensure smooth door operation. Do not use wet mops near furniture legs or skirts. When cleaning painted surfaces, avoid chemical cleaners—use a dry or damp cloth instead. Newly purchased furniture should not be exposed to direct sunlight or placed near heaters, as this can cause excessive moisture changes and lead to deformation.
