Flow-limiting mute water discharge valve

Technical Field

The utility model relates to a sanitary wares accessory especially relates to one kind and accomplishes under the prerequisite of normally opening, closing drainage function at the straight-bar control drain valve piece that does not influence to rise, sets up the current-limiting card at the middle part of straight-bar that rises, and the current-limiting card corresponds with the current-limiting movable card and separates the sky coincide, when the quiet people of night need the silence to wash, rotating knob handle is by the current-limiting movable card with the current-limiting card coupling and the random control drain valve piece size of washing flow and the length of washing time to realize the current-limiting silence drain valve of silence washing effect.

Background

Guangdong Chaozhou is the key manufacturing base for sanitary ware. It is known to those in the state of the tide that squats are used in 90% of households and that 90% of squats are not equipped with a water tank. Why? Indeed, the mystery of the inside deserves our thoughts.

The sanitary ware has strict performance detection indexes in China, and mainly has three aspects of washing power, replacement rate and water saving performance. For example, a product of a first-level water-saving mark can respectively convey 100 polyester balls for 14 dots and 2 meters or hold 7 artificial excrement and 8 paper rolls to completely flush out a sewage outlet under the condition that the consumption is not more than 4 dots and 2 liters, so that the design of a flow channel system is very scientific, the caliber of a drainage valve is particularly large, and the realization can be realized only by absolutely ensuring that the water pressure potential energy of a high water level cannot be lost. If it is desired to meet these criteria, the water to be scrubbed and sprayed must be filled at once. However, the water flow is loud, the noise of the toilet bowl during flushing is more than 72 decibels, and the squatting pan is loud.

It is known that the international organization for standardization recommends a noise sleep base of 30 db in order to protect the environment and physical health of people. A difference of 40 db between 30 db and 72 db, who is not awake when the night is still?

It is often said that: the mobile operation is required to be flexible, and the mobile operation cannot be realized. The research of the functions of the sanitary ware is concentrated for more than ten years, and the practical value of the sanitary ware is greatly felt. I think that: for sanitary wares in suite rooms, the problem of noise is the primary index of the sanitary wares, and other performance indexes are considered. When people sleep well, people can wash away excrement under low noise.

The problem is that the existing sanitary ware accessories only have standard parts, and a standard flushing process is realized by pressing a drain valve, so that the sound of water flow during flushing cannot be relieved, and no room for regulation and control exists.

How to solve the above problems is discussed below.

SUMMERY OF THE UTILITY MODEL

The above technical problem of the utility model is solved through providing the current-limiting silence drain valve of following structure, this current-limiting silence drain valve includes: drain valve assembly, built-in float, float fulcrum, float lever, button pole, the fulcrum that rises, conduction fulcrum, conduction pole, straight pole that rises, knob fulcrum, knob handle, flexible cable wire, current-limiting card, current-limiting location fulcrum, current-limiting activity card, big row position card, drain pipe, drainage sealing port, drainage valve block, big row's activity card fulcrum, big row's activity card, its characterized in that: under the premise of not influencing the ascending straight rod to control the drain valve plate to complete normally open and closed drainage functions, the middle part of the ascending straight rod is provided with the flow limiting clamp, the flow limiting clamp and the flow limiting movable clamp are correspondingly spaced and matched, when people need silent flushing at night, a knob handle is rotated, the flow limiting movable clamp and the flow limiting clamp are coupled, the flushing flow of the drain valve plate and the flushing time are controlled randomly, and therefore the silent flushing effect is achieved.

The utility model discloses current-limiting silence drain valve compares with the current drain valve performance in market has following advantage:

first, the ideal silence replacement function can be realized. In order to realize a good flushing function, the sanitary appliance must fully utilize the energy converted from potential energy of water level into kinetic energy for washing and replacement. If the water flow speed is low, the time for filling the water guide ring of the sanitary appliance is long, the kinetic energy loss is high, and the sanitary appliance cannot realize the optimal flushing function. However, if the water flows down quickly, the flushing noise is very loud, which is a contradiction for the requirement of silencing effect of the sanitary appliance in the suite. Furthermore, the national standard requires that 100 polyester balls are conveyed for 14 points and 2 meters, which is also a reference datum, and the sanitary ware cannot be used in a short time without extreme. The utility model discloses current-limiting silence drain valve is not only considering the silence effect but also compromise under the prerequisite of replacement effect, sets up the current-limiting card at the middle part of straight-bar that rises, and the current-limiting card corresponds with the current-limiting movable clamp and separates the sky coincide, and when the quiet people of night need the silence to wash, rotating knob handle is by the size that current-limiting movable clamp and current-limiting clamp coupling and random control drainage valve block washed the flow and the length of wash-out time to realize the effect that the silence was washed.

And secondly, the performance index of the daily use of the sanitary appliance is not influenced. If the special site only needs to meet the silencing effect in a special time period, and the normally-washed drainage valve has larger structural change and even influences the normal operation and the service life, the normal operation and the service life are not compensated. The utility model discloses current-limiting silence drain valve only sets up the current-limiting card at the middle part of the straight-bar that rises, does not have anything at ordinary times and adheres to on the current-limiting card, does not influence the function effect of cleaners and polishes daily use completely. The device is only used occasionally when silent flushing is particularly needed at night, but the significance is not very good.

Thirdly, the structure is simple and maintenance-free. If a drainage valve needs to control the flow of the drainage valve to realize the silencing effect and has a very simple structure and durability, the improvement is very valuable, and obviously, all drainage valves in the current market do not have the function. The utility model discloses current-limiting silence drain valve only sets up the current-limiting card at the middle part of rising straight-bar, does not have anything at ordinary times and adheres to on the current-limiting card, and this is succinct, practical design already. The knob handle is rotated to couple the flow-limiting movable clamp and the flow-limiting clamp and to control the flushing flow and the flushing time of the drainage valve plate at will, and this set of control device is a mature technical structure and needs no maintenance at ordinary times.

After the water pump is started, the total amount of single flushing and water draining is controlled by the large displacement clamp 17, the large displacement clamp fulcrum 21, the large displacement clamp 22, the float lever 4, the float fulcrum 3 and the built-in float 2. The current limiting card 14 and the current limiting live card 16 are correspondingly in clearance fit. The rotating handle 12 controls the opening and closing of the current-limiting movable card 16 and the current-limiting card 14 and the time through the rotating fulcrum 11, the telescopic steel cable 13 and the current-limiting positioning fulcrum 15. The opening and closing between the drain sealing port 19 on the drain pipe 18 and the drain valve plate 20 are flexible.

When the sanitary appliance is not used by people: the space between the drainage sealing port 19 and the drainage valve sheet 20 is in a closed state; the large position card 17 and the large movable card 22 are in a separated state; the current limit card 14 is separated from the current limit live card 16; the built-in float 2 is in a state of maximum buoyancy.

When people use the sanitary ware in a daily way: when the button 5 is pressed, the drain valve sheet 20 rises to the highest position and the large discharge position clamp 17 is clamped by the buoyancy of the float 2 through the large discharge movable clamp 22 until the water level drops to a certain degree, the built-in float 2 sinks to separate the large discharge movable clamp 22 from the large discharge position clamp 17, and the space between the drain sealing port 19 and the drain valve sheet 20 is in a closed state immediately. During this operation, the current limit live card 16 is not in any relationship with the current limit card 14.

When people use the sanitary ware in a night mute mode: the knob handle 12 is rotated, the current-limiting movable clamp 16 is immediately coupled with the current-limiting clamp 14 through the rotating fulcrum 11, the telescopic steel cable 13 and the current-limiting positioning fulcrum 15, the current-limiting clamp 14 is properly lifted, the opening amplitude of the drainage valve plate 20 is controlled according to the rotating amplitude of the knob handle 12, and the time for flushing can be automatically controlled. When the knob handle 12 is reset, the space between the drainage sealing port 19 and the drainage valve sheet 20 is immediately in a closed state. During this operation, large rank card 17 has no relationship with large rank card 22.

The current-limiting mute water discharge valve of the present invention can be changed and modified in various ways, and is not limited to the specific structure of the above embodiments, such as various changes of the structure of the current-limiting movable card and the current-limiting card.
