The utility model discloses a check valve passes through two screw fixation on the water route board, and plays sealed effect by two O type sealing washers for check valve and water route board only have 2 tie points, thereby have reduced the risk of leaking.
Description
Technical Field
The utility model relates to a water purification unit technical field, in particular to a check valve for on water route board.
Background
Most of existing water purifiers are all-in-one machines, and the existing water purifiers comprise a water circuit board with a preset pipeline, and a plurality of filtering components, one-way valves and other parts are installed on the water circuit board. And conventional check valve installs and need be connected through two PE union couplings on the water route board, and the check valve both ends respectively need fixed part through a PE union coupling to the water route board, and not only the connection of check valve and PE pipe needs extra fixed part, and the PE pipe needs fixed part with being connected of water route board equally for the assembly of check valve is complicated, and need bend when PE pipe installs, influences the life of pipeline, increases the cost of maintenance of purifier. Meanwhile, 2 connecting points are arranged at two ends of the check valve and on the water circuit board, which means that 4 water leakage points exist, and the hidden water leakage danger is large after the water circuit board is used for a long time.
Disclosure of Invention
The utility model aims at providing a simple structure reduces the check valve on the water route board of being exclusively used in of hidden danger of leaking.
Therefore, the technical scheme of the utility model is that: a check valve for waterway plate is characterized in that: the valve seat is internally provided with a passage for communicating the water inlet with the water outlet, and the whole passage is in an inverted U shape; a vertically arranged valve cavity is arranged in the water inlet, a pressing sheet, a spring and a valve block are arranged in the valve cavity, the pressing sheet is arranged at the bottom of the valve cavity, one end of the spring abuts against the pressing sheet, the other end of the spring abuts against the valve block, the spring is in a compressed state, and the valve block is blocked at the water inlet; and O-shaped sealing rings are arranged at the water inlet and the water outlet.
The water route board is equipped with two spliced poles in the position that needs the installation check valve, and the spliced pole side still has 2 erection columns, is equipped with the internal thread in the erection column, and the check valve is installed on the water route board, and the mounting hole of disk seat both sides is relative with the erection column position, through screw fixed mounting, and two spliced poles insert the water inlet of disk seat, delivery port respectively to seal through O type sealing washer, realize the seal installation of check valve.
The check valve is characterized in that fluid can only flow along the water inlet, but the medium at the water outlet can not flow back, when the water pressure of the water inlet is greater than the pressure of the spring, water flow pushes the valve block to move upwards, a gap is formed between the valve block and the water inlet, and therefore water flow flows to the water outlet through the internal passage of the valve seat. And if the water outlet is reversely filled with water, the pressure of the water flow and the pressure of the spring on the valve block are upward forces in the same direction, so that the valve block is more tightly blocked at the water inlet, the counter flow is effectively prevented, and the function of one-way water inlet is realized.
The utility model discloses reserve the space of installation check valve on the water route board, the spliced pole of mounted position, erection column all with water route board integrated into one piece, during the assembly, the direct mount check valve can. The check valve is fixed on the water way plate through two screws, and two O-shaped sealing rings play a role in sealing, so that only 2 connecting points are arranged between the check valve and the water way plate, and the risk of water leakage is reduced.
Drawings
The following detailed description is made with reference to the accompanying drawings and embodiments of the present invention
FIG. 1 is an exploded view of the components of the present invention;
fig. 2 is a sectional view of the internal structure of the present invention.
Labeled as: the device comprises a check valve 1, a mounting hole 11, a water inlet 12, a water outlet 13, a pressing sheet 14, a spring 15, a rubber plug 16, a valve block 17, an O-shaped sealing ring 18, a waterway plate 2, a connecting column 21, a mounting column 22 and a screw 3.
Detailed Description
See the drawings. The check valve 1 comprises a valve seat, wherein mounting holes 11 are formed in two sides of the valve seat, a water inlet 12 and a water outlet 13 with downward openings are formed in the valve seat, a passage for communicating the water inlet and the water outlet is formed in the valve seat, and the whole passage is in an inverted U shape; a vertically arranged valve cavity is arranged in the water inlet, a pressing sheet 14, a spring 15, a rubber plug 16 and a valve block 17 are arranged in the valve cavity, the pressing sheet 14 is arranged at the bottom of the valve cavity, one end of the spring 15 abuts against the pressing sheet 14, the other end of the spring 15 is sleeved on a spring mounting column of the rubber plug 16, the rubber plug abuts against the valve block 17, the spring is in a compressed state, and a downward force is applied to the rubber plug and the valve block, so that the valve block is blocked at the water inlet; when the water pressure at the water inlet is higher than the pressure of the spring 16, the water flow pushes the valve block 17 to move upwards, and a gap is formed between the valve block 17 and the water inlet 12, so that the water flow flows to the water outlet 13 through the internal passage of the valve seat. And O-shaped sealing rings 18 are also arranged at the water inlet 12 and the water outlet 13.
The position that the check valve 1 was installed in needs to water route board 2 is equipped with two spliced poles 21, spliced pole 21 side still has 2 erection columns 22, be equipped with the internal thread in the erection column, check valve 1 is installed on water route board 2, the mounting hole 11 and the erection column 22 position of disk seat both sides are relative, through 3 fixed mounting of screw, two spliced poles 21 insert the water inlet 12 of disk seat respectively, delivery port 13, and seal through O type sealing washer 18, realize the seal installation of check valve.
