The utility model provides a water level electric brake structure needs the design requirement who satisfies based on one-way pneumatic valve: the maximum value of the friction force overcome when the moving contact goes out of the metal buckle is set as Fmax1, and the maximum value of the friction force overcome when the moving contact enters the metal buckle is set as Fmax 2. Assuming that the floating block is a regular cylinder, the bottom area is S, and the height is h, but because the density of the material used by the floating block is close to that of water, a regular cylinder with the volume of V is drilled under the floating block during design, and the total mass of the floating block is m. The tap water has a density ρ. The position of the floating block when the water level is zero is taken as the origin of coordinates, the vertical direction is the positive direction, and L < h is required to exist during design, so that Fmax1+ mg is rho LSg. Assuming that the floating block can generate x displacement difference between closing and opening, the resultant force does work to zero in the process of floating to the highest position, and an integral expression is provided:
f (x) ═ ρ (L-x) Sg-mg, (here, the resistance of the air flow to the floes in a closed environment is not considered)
Then the solution is: b 2Fmax1/ρ Sg … … (1-1)
And the stress balance generates the final state of the distance difference,
then mg ═ ρ S (L-X1) g … … (1-2)
The floating block can automatically close the electric brake when the water level is zero only by combining the two formulas (1-1) and (1-2) and the condition of Fmax1+ mg ═ ρ LSg to obtain 2 × 1 ═ b, namely b > X1, so that the distance difference in the final state is X1 ═ L-m/(ρ S) ═ Fmax1/ρ Sg, and when Fmax2< mg, namely m > Fmax 2/g. Therefore, a minimum volume difference coefficient k caused by the water level reduction in the one-way air valve pipe is designed, wherein rho (SL-k) is not less than m, and Fmax1/g is greater than rho k when Fmax1+ mg is rho LSg < rho hSg. To sum up, m satisfies the interval (Fmax2/g, rhohs-Fmax 1/g ] … … (1-3)
The formula shows that the requirement on the quality of the floating block is met, Fmax1 is not required to be larger than Fmax2, but Fmax1 with a certain size is required, so that a structure that the movable contact is difficult to be buckled by metal, namely a fixed contact is adopted, is designed. When in design, the static contact adopts a structure as small as possible on the premise of meeting the requirement that the contact area of a metal part reaches a safety index.
A layer of insulator is designed below a moving contact of the floating block device, so that when a person in a house goes out, a circuit is prevented from being opened for a moment and closed for a moment; and because the density of the material used by the floating block is close to that of water, a blind hole with the volume of V is processed under the floating block during design.
The valve body cannot meet the required quality due to the fact that the density of the used ppr material is too low, and a spring needs to be added. The sealing work spring force is that the selected spring is 0.5mm in wire diameter, 8mm in outer diameter and 15mm in length, the material is 65Mn spring steel, and the shear modulus G is 78.5 GPa. When the spring works, the total compression deformation is changed into that lambda is 1.8mm, the effective turn number n is 3, d is 0.5mm, and R is 8mm/2 is 4 mm. The spring is subjected to a pressure Fsp λ G d4/(64*R3N) 0.7187N. Finally, F + mg is 0.7482N.
The one-way valve port part satisfies the end face specific pressure Pc-F/A-0.7482/4.77 MPa-0.1569 MPa>Psp is 0.15Mpa, and the end face spring specific pressure Psp is 0.15 Mpa. It is a nearly airtight one-way valve port, but it requires the calculation of the drop in water level inside the sleeve due to the drop in water level outside the tube. The gas inside the sleeve is isothermally changed in the process of falling of the external water level, and P can be utilized1V1＝P2V2The water level drop amount delta h in the immersion pipe under the condition of no air leakage can be calculated, and in order to increase the robustness of the work, the safety factor n is 2, and k is 2. With k, the floating block 2 can be calculated by substituting the formula (1-3)The mass interval of (2). The volume V of the float portion can be calculated by taking a value within the interval, as well as other parameters L, h, b, etc. Thus, the sizes of all parts of the work can be ensured.
The material selection of a water level electric brake product based on a one-way air valve comprises the following steps: the metal buckle is made of stainless steel with the mark number of 10Cr 17; the binding post and the moving contact are made of pure copper; the bolt part is a galvanized product; the serial-type socket in fig. 7 and 8 can be made of conventional socket materials; the spring is made of spring steel with the mark of 65 Mn; the piston ring is made of a piston material; the other parts are all ppr materials.
The water level switch based on one-way air valve uses the calculation formula based on the maximum likelihood estimation of timing truncation samples to estimate the average effective days of the work, and the average effective days are used as a parameter for quality detection of the work, and the standard of the effective days is set to be 3 days or more than 3 days. The calculation formula is as follows:
wherein s (t)m)＝t1+t2+t3+(n-m)tm。
The utility model discloses a theory of operation is:

A floating block which is embedded with a transverse moving contact and can move up and down is arranged in the tube. The storage container on the roof is used for domestic water, when the water level in the storage container is lower than the lower pipe orifice of the water immersion pipe, all the original water in the water immersion pipe flows out, the floating block moves downwards, the water level switch is closed, the water pump starts to work, and the water level of the water immersion pipe starts to rise; when the water level reaches the preset position, due to the structural characteristics of the specially-made metal buckle, the floating block moves upwards in a jumping mode to form a circuit disconnection interval with a certain size, the water pump stops working, and the water pump runs back and forth in the mode.
The functions are as follows: has the functions of automatic water pumping in water shortage, automatic water pumping stop after water is full and intermediate maintenance.

The back of the serial socket is provided with a three-pin plug. When the water pump socket is used, the plugs of the purely mechanical electric brake and the water pump are inserted into the jacks of the water pump, and then the plugs of the water pump and the water pump are inserted into the conventional socket. The circuit connection is designed to be convenient and safe. The serial socket is different from a common socket, and two types of jacks can only be connected in series to a household circuit.

Both markets can be approached with both hands, and the size of both hands is set through social research. The first hand is the agreement with the dealer selling the pumps to write "xx brand pumps, send you a level controller" on the product and require in the agreement that only the pumps can be priced. Therefore, the product can achieve the effects of 'buying unnecessary and using unnecessary', thereby increasing the popularization rate of the water level switch and reducing the cost of the selling link; the second hand is in the conventional panning market and can be entered into the user market already with the pump. In order to price the pump normally on the panning stage, the merchant who needs to sell the pump cannot expose the price of the product. In addition, all control systems need to be improved in energy-saving measures, the energy-saving cost is low, and the application prospect is wide in the user market with low economic water level and culture level. Therefore, the water and electricity saving quantity in the southern China is increased.
The utility model discloses circuit connection and equipment fixing are simple and easy, be applicable to the water pumper of different power and can will save water and electricity and establish on low-cost high safe basis, and this has just solved a great deal of weak point of electronic type water level switch on the current market, has promoted the reduction once more of the water electric quantity of wasting of the area of south on the other side in china.
