Description

A water heating equipment valve

Technical Field

The utility model relates to a valve for water heating equipment.

Background technique

The wall-mounted boiler can not only heat the heating water and transport the heating water to the radiator to achieve indoor heating, but also use the hot heating water to heat the domestic water. The tap water is directly heated to the actual required temperature through the heating water for use. The valve for the flow of domestic water and the valve for the flow of heating water are independent, which effectively avoids the mixing of heating water and domestic water and causes pollution of domestic water. However, in the actual use of the wall-mounted boiler, the wall-mounted boiler will have low water pressure, so it is necessary to replenish the wall-mounted boiler frequently. The traditional way of replenishing water is to process an opening on the valve for the flow of heating water, and then install and fix a water replenishment joint that can be opened and closed. The water replenishment joint also needs to be connected to the water source through a new pipe. The appearance of the new pipe will affect the overall pipeline distribution of the wall-mounted boiler, resulting in the complication of the pipeline distribution of the wall-mounted boiler, which is not conducive to maintenance and replacement. At the same time, domestic water exists independently. In addition to providing life use, it no longer has other functions. The single function makes it impossible to effectively and fully utilize the resources of domestic water.

An annular sealing gasket 20 is provided between the right side wall of the limiting plate 13 and the left side wall of the fixing seat 11, and the sealing gasket 20 is made of rubber; the outer wall of the sealing gasket 20 is in contact with the inner wall of the central valve body 1; the inner wall of the sealing gasket 20 is provided with an annular embedding groove 21, and the outer edge of the one-way plate 14 is embedded in the embedding groove 21, and the inner wall of the embedding groove 21 is in contact with the surface of the one-way plate 14.

The method of using the utility model is as follows:

The water connection 7 of the heating water valve body 6 can be used to connect the pipeline for the flow of heating water, and the domestic water connection 8 can be used to connect the pipeline for the flow of domestic water. When the valve ball is closed, the middle part of the central valve body 1 is equivalent to being directly isolated, so that the domestic water and the heating water cannot intersect through the central valve body 1, so that the domestic water is contaminated by the heating water.

When the domestic water connector 8 is connected to the pipeline, the domestic water will flow through the left end of the central valve body 1. At this time, a part of the domestic water will flow to the right under the action of water pressure, and then flow into the one-way hole 15 through the left end opening of the one-way hole 15. The water pressure of the domestic water is greater than the elasticity of the rubber valve plate 16 itself. As the domestic water continues to flow to the right, the domestic water will squeeze the rubber valve plate 16 to the right. The rubber valve plate 16 will be deformed and no longer fit tightly with the right side wall of the one-way plate 14. At this moment, the domestic water can continue to flow to the right to the water supply hole 12 through the gap between the right side wall of the one-way plate 14 and the left side wall of the rubber valve plate 16. If the valve ball 2 is in a closed state at this time, the domestic water will be stopped by the valve ball 2, so that it cannot continue to flow to the right.

If it is necessary to replenish the heating water during actual use, the valve ball 2 can be opened, and the hand wheel 4 can be turned at this time to make the hand wheel 4 drive the valve ball 2 to rotate through the valve stem 3, so that the opening and closing hole 5 in the center of the valve ball 2 is no longer blocked and sealed by the inner wall of the central valve body 1, so that the left space and the right space of the central valve body 1 can be connected through the opening and closing hole 5 in the center of the valve ball 2. At this time, the domestic water flowing to the valve ball through the water replenishment hole 12 is no longer blocked by the valve ball 2, but can flow into the right space of the central valve body 1 through the opening and closing hole 5 in the center of the valve ball 2, and finally flow into the pipeline connected to the water connection joint 7 through the heating water valve body, and finally mix with the heating water in the pipeline, so that the heating water is effectively replenished and the water replenishment is completed.

Although with the opening of the valve ball 2, the left space of the central valve body 1 is connected with the right space of the valve body 0, there is no need to worry about the heating water flowing to the left and causing domestic water to be contaminated. When the heating water flows to the left, the heating water will flow into the water supply hole 12 through the opening and closing hole 5. When the heating water flows out of the water supply hole 12, the heating water will directly impact the right side wall of the rubber valve plate 16, thereby pushing the rubber valve plate 16 to the right. When the rubber valve plate 16 is pushed to the right, the left side wall of the rubber valve plate 16 is further pressed against the right side wall of the one-way plate 14, thereby effectively shielding and sealing the right end of the one-way hole 15. When the one-way hole 15 is sealed, the heating water cannot continue to flow to the left and intersect with the domestic water, thereby avoiding the domestic water from being contaminated by the heating water.

From the above, it can be known that the utility model can open the valve ball 2 by the hand wheel to directly introduce domestic water into the heating water. When the water pressure of the wall-mounted boiler is insufficient, the heating water can be directly replenished with domestic water, so that the domestic water can be used not only for normal life needs, but also for replenishing water, so that the resources of domestic water can be effectively and fully utilized, and the heating water valve body does not need to be provided with a special joint for connecting the water replenishment pipeline, which effectively reduces the number of pipelines and avoids the situation of numerous pipelines. At the same time, when domestic water is used to replenish heating water, the rubber valve sheet can be used to limit the flow direction of heating water to avoid the situation where heating water flows into domestic water and causes domestic water to be contaminated.

A limiting hole 17 is provided at the center of the one-way plate 14, and a plurality of one-way holes 15 evenly distributed on the circumference enclose the limiting hole 17. A limiting column 18 matching the limiting hole 17 is provided at the center of the left side wall of the rubber valve sheet 16, and a limiting head 19 that fits the left side wall of the one-way plate 14 is provided at the left end of the limiting column 18. This fixing method facilitates the disassembly and assembly between the rubber valve sheet 16 and the one-way plate 14, and is beneficial to the replacement of the rubber valve sheet 16. When the limiting head 19, the limiting column 18 and the rubber valve sheet 16 are integrally formed and are all made of rubber material, and the diameter of the limiting head 19 gradually decreases from right to left, the limiting head 19 can be easily squeezed from right to left into the limiting hole 17, and squeezed out from the left end of the limiting hole 17, thereby quickly completing the installation of the rubber valve sheet 16.

An annular sealing gasket 20 is provided between the right side wall of the limiting plate 13 and the left side wall of the fixing seat 11. The sealing gasket 20 is made of rubber. The outer wall of the sealing gasket 20 fits with the inner wall of the center valve body 1. The inner wall of the sealing gasket 20 is provided with an annular embedding groove 21. The outer edge of the one-way plate 14 is embedded in the embedding groove 21. The inner wall of the embedding groove 21 fits with the surface of the one-way plate 14. The presence of the sealing gasket 20 can effectively improve the sealing between the outer peripheral surface of the one-way plate 14 and the inner wall of the center valve body 1, ensuring that the water flow can only flow through the one-way hole 15, thereby preventing the heating water from leaking through the gap between the outer peripheral surface of the one-way plate 14 and the inner wall of the center valve body 1 to the left end space of the center valve body 1 and intersecting with the domestic water.

The limiting plate 13 and the fixing seat 11 are both screwed into the central valve body 1 through threads. This fixing method of the limiting plate 13 and the fixing seat 11 facilitates the disassembly and assembly of the limiting plate 13 and the fixing seat 11.

The inner wall of the water inlet hole 22 is a regular hexagon, and a regular hexagonal groove 23 is provided at the left end of the water replenishment hole 12. The limit plate 13 can be easily rotated by simply inserting an inner hexagonal wrench matching the water inlet hole 22 into the water inlet hole 22. The limit plate 13 can be easily rotated by simply inserting an inner hexagonal wrench matching the regular hexagonal groove 23 into the regular hexagonal groove 23, which facilitates the replacement of the limit plate 13 and the fixing seat 11 to the greatest extent.

A left sealing step 24 in the shape of an annular ring is provided at the right end of the water supply hole 12, and a left sealing ring 25 is provided on the left sealing step 24 and is located outside the left end of the valve ball 2. A right sealing step 26 is provided in the central valve body 1 and is located on the right side of the valve ball 2. The right sealing step 26 is annular, and a right sealing ring 27 is provided on the right sealing step 26 and is located outside the right end of the valve ball 2. The existence of the left sealing ring 25 and the right sealing ring 27 can effectively ensure the sealing of the valve ball 2 when opening and closing, and has a water leakage prevention effect.

A limiting rib 28 that fits with the left end face of the center valve body 1 extends outward from the outer edge of the plug 10. The fit between the limiting rib 28 and the left end face of the center valve body 1 can form a seal. On the basis of the threaded seal between the plug 10 and the threaded hole 9, the sealing performance of the plug 10 is further improved to avoid water leakage. A rotating hole 29 is provided in the center of the left end face of the plug 10. The rotating hole 29 is a regular hexagon. The plug 10 can be easily rotated by simply inserting an inner hexagon wrench matching the rotating hole 29 into the rotating hole 29, which facilitates the disassembly and assembly of the plug 10.

An annular step 30 is provided on the inner wall of the left end of the threaded hole 9, and an annular groove 31 is provided on the left end of the plug 10 and is opposite to the annular step 30. An O-ring 32 matching the annular groove 31 is provided in the annular groove 31. The outer edge of the O-ring 32 protrudes outward from the annular groove 31 and fits with the inner wall of the annular step 30. The presence of the O-ring 32 can further improve the sealing effect of the plug 10.
