The operation principle of the water supply device 10 for realizing chemical blending by the pressure reducing valve will be described below:
the water flow in the main water supply pipe 20 is reduced by the pressure reducing valve 50 to reach each branch pipe 30, and when the water is needed, the valve of the water outlet tap 40 in each branch pipe 30 is opened, so that the water flow can come out from the water outlet tap 40;
during the process of the water flow passing through the main water supply pipeline 20, the pressure reducing valve 50 works concomitantly, on one hand, the pressure reduction of the water flow can be realized, and on the other hand, corresponding chemical agents can be blended in the water flow;
it should be noted that the chemical agent storage tank 800 contains corresponding chemical agents, such as disinfectant, cleaning solution, etc.; the open end of the chemical agent storage tank 800 is inserted into the first through hole 210, and at this time, the chemical agent in the chemical agent storage tank 800 does not overflow due to being blocked by the opening plug 910, and the chemical agent can enter the water outlet pipe 400 through the first through hole 210 and the second through hole 420 only by opening the opening plug 910;
specifically, water flow at one end of the main water supply pipeline 20 enters the water body pressure reduction cavity 102 formed by the valve body 100 and the cover body 200 through the water inlet pipe 300, the water flow in the water body pressure reduction cavity 102 impacts the membrane 500 in the cavity, the impacted membrane 500 is separated from the end surface of the water body pressure reduction cylinder 410, so that an opening is formed between the membrane 500 and the water body pressure reduction cylinder 410, the water flow in the cavity enters the cylinder of the water body pressure reduction cylinder 410 through the opening, and then the cylinder of the water body pressure reduction cylinder 410 reaches the other end of the main water supply pipeline 20 through the water outlet pipe 400, so that the water flow in the main water supply pipeline 20 is reduced in pressure;
when the pressure reducing valve 50 reduces the pressure of the water in the main water supply pipeline 20, the diaphragm 500 is deformed due to the impact of water flow, the deformed diaphragm 500 drives the lever 920 to rotate, and the rotating lever 920 further drives the opening and closing plug 910 connected with the lever to move, so that the opening and closing plug 910 originally plugged at the opening end of the chemical agent storage tank 800 is opened, and thus, the chemical agent in the chemical agent storage tank 800 enters the water outlet pipe 400 through the first through hole 210 and the second through hole 420; therefore, the chemical agent in the chemical agent storage tank 800 enters each branch pipeline 30 along with the water flow and then comes out from the water outlet faucet 40, so that the automatic blending of the chemical agent is realized;
when the main water supply pipeline 20 stops supplying water to each branch pipeline 30, that is, the water flow in the main water supply pipeline 20 stops flowing, so that the diaphragm 500 is reset under the elastic restoring force of the pressure regulating elastic member 700, and then the diaphragm 500 is pressed against the end surface of the water body pressure reducing cylinder 410 again, the port of the water body pressure reducing cylinder 410 is closed, and the water flow cannot enter the water body pressure reducing cylinder 410 again; after the diaphragm 500 is reset, the diaphragm 500 drives the lever 920 to rotate reversely, the lever 920 in the reverse rotation drives the opening and closing plug 910 connected with the lever 920 to move reversely, then the opening and closing plug 910 seals the opening end of the chemical agent storage tank 800 again, and at this time, the chemical agent in the chemical agent storage tank 800 cannot overflow;
it should be further noted that, by screwing the adjusting screw 600, the pressing force of the pressure-adjusting elastic member 700 on the diaphragm 500 can be adjusted, so that the diaphragm 500 can be elastically deformed only by a certain water flow impact force.
Further, the hole wall of the first passage hole 210 is formed with an internal thread 211 (as shown in fig. 5), and the open end of the chemical storage tank 800 is formed with an external thread 810 (as shown in fig. 6), so that the chemical storage tank 800 can be more stably fixed to the first passage hole 210 by screwing the external thread 810 and the internal thread 211. Furthermore, the chemical agent storage tank 800 is provided with air holes (not shown), and the chemical agent in the chemical agent storage tank 800 can be discharged more smoothly through the air holes.
Further, a return spring 212 (as shown in fig. 6) is disposed in the first through hole 210, one end of the return spring 212 abuts against the hole wall of the first through hole 210, and the other end abuts against the opening/closing plug 910. Thus, the restoring spring 212 can make the opening block 910 tightly close the opening end of the chemical storage tank 800, and prevent the chemical in the chemical storage tank 800 from overflowing if necessary, and the opening block 910 will be separated from the opening end of the chemical storage tank 800 only by applying a force to the opening block 910 by the lever 920.
According to the water supply device 10 for realizing chemical agent blending by using the pressure reducing valve, the structure of the pressure reducing valve 50 is particularly optimized by arranging the main water supply pipeline 20 and the plurality of branch pipelines 30 communicated with the main water supply pipeline 20, and the chemical agent is automatically filled into a water body by using the opening and closing functions of the pressure reducing valve without manually adding the chemical agent additionally.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
