Description

Technical Field

[0001] The utility model belongs to the technical field of control valves, and particularly relates to a salt path closing assembly. Background Art

[0002] A water softener is a device that removes calcium and magnesium ions in water through ion exchange resin to reduce water hardness. The water softener has a softening effect on water quality, can remove calcium and magnesium ions in water, make the water quality softer, and has a good improvement effect on daily life water such as washing, bathing, and shampooing. At the same time, the water softener can also be used in industrial fields, such as equipment that requires soft water like boilers and air conditioners. The water softener is an efficient and environmentally friendly device that can improve the quality of domestic water and is also one of the indispensable devices in the industrial field.

[0003] The purified water of the water softener is that hard water enters the resin tank through the control valve, and the water treated by the exchanger flows through the bottom separator, up through the lifting pipe, and then out through the control valve. The backwashing of the water softener is that hard water enters the control valve, flows from top to bottom through the central lifting pipe to the bottom flow divider, backwashes the exchanger from bottom to top, and then is discharged through the sewage outlet of the control valve. The regeneration of the water softener is that after hard water enters the control valve, it enters the injector from above, then sucks the reducing agent in the salt tank through the jet process, and the water flow with the reducing agent flows downward through the exchanger layer into the flow divider and the lifting pipe, and then is discharged through the drain outlet of the control valve.

[0004] The core component of the water softener is the control valve. The functions of the control valve include realizing the switching of different water paths such as purified water, backwashing, salt absorption regeneration, normal washing, and water injection.

[0005] Therefore, there is an urgent need for a salt path switching assembly that matches the control valve. Content of the Utility Model

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 is a schematic structural diagram of the salt path switching component of the present utility model;

[0017] Figure 2 is an exploded view of the salt path switching component of the present utility model. DETAILED DESCRIPTION OF THE INVENTION

[0018] The technical solutions of the present utility model will be further described in detail below with reference to the drawings.

[0019] Such as Figure 1 and Figure 2As shown, the salt path switching component of the utility model is matched with the salt path channel of the water softener control valve, so that it is closed in the normal state, and the salt path channel is closed; when salt absorption or water replenishment is required, the component is made to open the salt path channel in the corresponding control valve. The salt path switching component includes a fixed rod 2, and one end of the fixed rod 2 (which can be understood as the front end) is connected to a soft seat 3, which forms an internal sealing connection with the front end of the fixed rod 2. The other end of the fixed rod 2 (which can be understood as the tail end) is connected to a drive motor 9, so that the motor 9 drives the fixed rod 2 to move forward and backward.

[0020] The end of the fixed rod 2 near the soft seat 3 is sleeved with a bracket 1, which is a hollow bracket 1, and the side wall of the bracket 1 is provided with a plurality of salt passages connected to the inside thereof. There is also a gap of the salt passage between the fixed rod 2 and the bracket 1, so that when salt absorption or water replenishment is required, it can enter from the side wall of the bracket 1, circulate through the inside thereof, and then flow out from the end of the bracket 1 near the soft seat 3, and then the salt passage on the corresponding control valve is opened. The opening and closing of the salt passages of the bracket 1 and the fixed rod 2 are realized by the soft seat 3. Specifically, the soft seat 3 is arranged between the front end of the fixed rod 2 and the front end of the bracket 1, and the soft seat 3 is sleeved on the fixed rod 2. It is a hemispherical structure with a through hole, and the long diameter end is fixedly connected to the fixed rod 2 to realize the internal sealing connection, and the end of the fixed rod 2 is extended with a side edge that forms an internal sealing connection with the soft seat 3. The short diameter end of the soft seat 3 is movably connected to the front end of the bracket 1 to realize the compression seal between the soft seat 3 and the bracket 1.

[0021] The rear end of the bracket 1 is connected with a top cover 4. Similarly, the top cover 4 is sleeved on the fixed rod 2. The top cover 4 is connected with an elastic element 5, preferably a spring, and the other end of the spring is limited by a retaining spring sleeved on the fixed rod 2. A support sheet 8 is also provided between the top cover 4 and the retaining spring 6, which is equivalent to limiting the forward and backward movement of the fixed rod 2. That is, the fixed rod 2 of the salt road closing assembly of the utility model can slide forward and backward in the bracket 1 and the top cover 4, and the fixed rod 2 and the soft seat 3 are fixedly connected as a whole. When the motor 9 drives the fixed rod 2 to move forward, the soft seat 3 and the fixed rod 2 will be separated from the bracket 1, and then there is a flow channel between the soft seat 3 and the bracket 1, so as to realize the open state of the salt road channel for salt absorption or water replenishment; when the motor 9 drives the fixed rod 2 to move backward, that is, the fixed rod 2 contracts, and a compression seal connection is formed between the soft seat 3 and the bracket 1, so as to realize the closed state of the salt road channel.

[0022] In addition to the above, in order to further improve the sealing performance between the salt road closing assembly and the salt road channel of the control valve and the sealing performance between various components, a sealing ring 7 is also provided between the bracket 1 and the top cover 4.
