Two-way adjusting valve element and two-way adjusting valve

Abstract

The invention discloses a two-way adjusting valve element and a two-way adjusting valve and relates to the field of valves. According to the technical scheme, in order to facilitate adjusting of magnitude of water flow of two ways, by changing the structure of a static sealing block and a movable sealing block, flow of cold water and flow of hot water can be controlled at the same time, the two-way adjusting valve is designed by utilizing the valve element, and the water flow of the two ways can be adjusted rapidly and easily through one handle.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a two-way regulating valve core and a two-way regulating valve. technical background [0002] Bernoulli's principle is the "Bernoulli's principle" proposed by Daniel Bernoulli in 1726. This is the basic principle adopted by hydraulics before the establishment of the continuum theoretical equation of hydraulics, and its essence is the conservation of mechanical energy of water. That is: kinetic energy + gravitational potential energy + pressure potential energy = constant. Its most famous inference is: when the flow is at a constant height, the flow rate is high and the pressure is small. Bernoulli's principle is often expressed as p+1 / 2ρv2+ρgh=C, and this formula is called Bernoulli's equation. In the formula, p is the pressure at a certain point in the water, v is the velocity of the water at that point, ρ is the water density, g is the acceleration of gravity, h is the height...

Problems solved by technology

[0003] Mixing of cold and hot water is often encountered in domestic water. In the mixing of cold and hot water in daily life, the pressure of hot water is often insufficient and the pressure of cold water is high. Large, in this case, there will be problems in the mixing of cold water and hot water. For example, due to the large pressure difference, it is easy to make the flow of cold water large and make adjustment difficult. Even if the temperature is adjusted to a suitable temperature, it is limited by the pressure of hot water. The total water output will be greatly limited. For example, the pressure of commonly used solar water heaters mainly depends on the liquid column pressure generated by the height difference. For rural areas where solar water heaters are widely used and residents on the top floors of buildings, the height difference is greatly restricted. That is, the pressure of the hot water cannot be met by the liquid column pressure, which has a great impact on the use. In the traditional technical solution, the pressure relief valve can be used to reduce the pressure of the cold water. This situation also limits the water output; in order to solve this problem The problem can also pressurize the hot water. For example, in order to increase the pressure of hot water in common electric water heaters, the water storage space is designed to be sealed, and the cold water inlet is connected to the water storage space, so that the pressure of the cold water can be used to make the water storage space The pressure increases to the same pressure as the cold water, that is, the hot water tank of the water heater is under pressure at this time, thus solving the problem of pressure difference caused by the mixing of cold and hot water, but this design leads to a complicated structure; The water is pressurized through the pump, and the addition of the pump will also bring other effects, such as the stability, safety and noise of the pump, which cannot be ignored, so this problem has become a problem that has not been effectively solved for a long time. This problem also limits the installation of solar energy in high-rise buildings. If it is installed on the roof of a high-rise building, it will cause insufficient hot water pressure for the residents on the top floor. Residents below the top floor will be difficult to install due to the long installation length of the pipeline. High cost The problem is that the amount of water stored in the pipeline is too long. If the insulation is not good, this part of the water will be cooled and wasted. At the same time, there is also the current situation that hot water cannot be produced in time. If it is installed on this floor, it will also lead to insufficient pressure. The problem of excessive pressure difference between hot and cold water
