The invention provides a water tap with a layered structure. The water tap comprises an inner functional layer and a casing layer. The casing layer is arranged outside the inner functional layer. Theinner functional layer comprises a base frame provided with a water through body. The water tap comprises the inner functional layer and the casing layer; the layered design greatly improves the universality of product components; and during the production, different casing layers can share inner functional layers with the same specification, therefore, the production cost is saved. Preferably, the inner functional layer can be single-layer or multilayer, wherein a plurality of layers can be mutually separable or inseparable. As for the water taps with different types, most components thereofcan be commonly use by means of simplification, thereby accelerating the production period and greatly reducing the requirements on the design and production of the components. Except a water throughlayer of the inner functional layer, other components are not contacted with water flow, therefore, no sealing requirement is imposed upon an outer layer of the water tap.

The invention discloses a cold-hot water mixing valve body with an upper water outlet passage and a lower water outlet passage. The cold-hot water mixing valve body comprises a generally cross valve casing. Water inlet passages are arranged in the middle of a left arm of the valve casing and in the middle of a right arm of the valve casing. Separated water outlet passages are arranged in the middle of an upper arm of the valve casing and in the middle of a lower arm of the valve casing. A spool mounting passage is arranged at the connection of the left arm, the right arm, the upper arm and the lower arm. The water inlet passage of the left arm is communicated with the water inlet passage of the right arm through the spool mounting passage. A spool positioning partition is disposed at the bottom of the spool mounting passage. A rear partition is connected between the rear of the spool positioning partition and the valve casing. Through holes for communicating the water outlet passage of the upper arm and the water outlet passage of the lower arm are arranged on the upper side and the lower side of the end face of the spool positioning partition. A spool positioning hole is arranged on each of the left side and the right side of the end face of the spool positioning partition. Lower ends of the left spool positioning hole and the right spool positioning hole are communicated with the water inlet passage of the left arm and the water inlet passage of the right arm respectively. Water can be discharged from the upper water outlet passage and the lower water outlet passage simultaneously by the aid of the cold-hot water mixing valve body which is high in use reliability.

The invention relates to the technical field of water utilization devices, in particular to an integrated electromagnetic valve structure and a pipeline water dispenser. The integrated electromagnetic valve structure comprises a valve body. An electromagnetic valve unit is arranged in the valve body and comprises a main spring, a movable iron core, a battery cell, a diaphragm plate, a water inlet for flowing water to flow in, and a water outlet for the flowing water to flow out. The integrated electromagnetic valve structure further comprises a water inlet channel communicating with the water inlet. The movable iron core is driven to seal or open a water passing hole under the attraction effect of the battery cell so that the water inlet channel can be sealed or opened. A pressure reduction valve unit is further arranged in the valve body and located at the connection position of the water inlet channel and the water outlet so that the water pressure change value of the water outlet can be kept within a certain range. The pipeline water dispenser comprises a water entrance. The integrated electromagnetic valve structure is connected to the water entrance. Use of matched materials is reduced, water leakage points of complete machines are reduced, the water leakage possibility is lowered, and the assembly efficiency is improved.

The invention discloses a waterway IC (Integrated Chip) comprising a body, a water inlet, a pure water outlet, a concentrated water outlet and fifteen blind holes. The water inlet, the pure water outlet and the concentrated water outlet are arranged leftwards from the right end surface of the body, the right rear part of the body, which is perpendicular to the upper surface of the body, is provided with the fifteen blind holes, wherein the first blind hole is communicated with the water inlet through a waterway, the second blind hole and the third blind hole, the fourth blind hole and the fifth blind hole as well as the sixth blind hole and the seventh blind hole are respectively communicated through corresponding waterways, the eighth blind hole, the tenth blind hole and the eleven blindhole are communicated through a waterway, the twelve blind hole is communicated with the pure water outlet through a waterway, the ninth blind hole is communicated with the thirteenth blind hole through a waterway, and the fourteenth blind hole and the fifteenth blind hole are respectively communicated with the concentrated water outlet through corresponding waterways. The invention has smart conception and simple structure and can rapidly integrate and connect elements and filter columns on a water purification machine together just like conveniently and rapidly insert elements on a circuit board so as to provide extreme convenience for replacing the elements and the filter columns.

The invention provides a fiber enhanced type wet paving / pre-paving waterproof coil material and a special construction method of the fiber enhanced type wet paving / pre-paving waterproof coil material for water prevention of an underground engineering bottom plate. The waterproof coil material comprises a fiber enhancing layer, an upper adhesive layer, a tread layer, a lower adhesive layer and an isolating membrane. The construction method comprises the following steps: (1) constructing a concrete cushion layer of the underground engineering bottom plate; (2) wetly paving a fiber enhanced type wet paving / pre-paving waterproof coil material; and (3) bundling bottom plate structure steel bars on the fiber enhancing layer and pouring bottom plate structure concrete. According to the fiber enhanced type wet paving / pre-paving waterproof coil material and the construction method, wet paving and pre-paving construction manners in a waterproof coil material construction process are combined together; a waterproof structure is simple, and waterproof and safe dual guarantees are realized; and the probability of water leakage is effectively reduced.
