Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of exhaust valves, and in particular to exhaust valves. Background Technology
[0002] Most air vent valves currently on the market are quantitative air vent valves, which can only vent air and not drain it. Some pipes, such as heating pipes, require a large volume of air to be vented, making these valves inconvenient to use. Some products also require drainage, such as those on electric boilers. Therefore, it is essential to design an air vent valve that can both vent and drain air, with an adjustable vent volume. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides an exhaust valve.
[0004] This utility model discloses an exhaust valve comprising a lower valve body, a bracket, a positioning pin, an upper valve body, and a valve core. The lower valve body has an inlet at its bottom end, and a bracket is located inside the lower valve body at its bottom. The positioning pin is mounted on the bracket. The valve core is installed inside the upper valve body, with its output end extending to the outside of the upper valve body. The upper valve body cover is mounted on the top of the lower valve body. The valve also includes an exhaust assembly. The upper valve body has an exhaust assembly at its input end, and a float assembly is mounted on the positioning pin. The float assembly and the exhaust assembly are detachably connected. In use, water enters the lower and upper valve bodies through the inlet. The exhaust assembly keeps the input end of the upper valve body sealed. When water and air enter the lower and upper valve bodies, the air pressure causes the float assembly to descend, thereby releasing the seal on the valve core input end and allowing air to escape through the valve core. When water re-enters the lower and upper valve bodies, the exhaust assembly re-seals the valve core input end, improving convenience.
[0005] Preferably, the valve comprises a spring, a copper rod, a round cap, and a sealing gasket. The first end of the spring is fitted onto the outside of the output end of the upper valve body, and the second end of the spring is fitted onto the first end of the copper rod. The second end of the copper rod is provided with a round cap, and the first end of the copper rod has a sealing gasket installed on its inner side. The sealing gasket seals the input end of the valve core. When water enters the lower and upper valve bodies, the float assembly floats, thereby keeping the spring in a horizontal state, thus sealing the round cap on the copper rod against the input end of the valve core. When air enters the lower and upper valve bodies, the float assembly descends, causing the copper rod to tilt, further releasing the sealing gasket from the inside of the valve core, allowing air to escape through the valve core. When water re-enters the lower and upper valve bodies, the float assembly floats up, the spring returns to a horizontal state, thus resealing the input end of the valve core with the sealing gasket.
[0006] Preferably, the float assembly includes a float body, a through hole, an outer edge, and a convex opening. The float body has through holes at the top and bottom, an outer edge at the top, and a convex opening on the outer edge. The float body is placed inside the lower valve body, a positioning pin passes through the through hole, a round cap passes through the convex opening, and a copper rod enters the top of the convex opening. The positioning pin causes the float body to float up and down inside the lower and upper valve bodies, improving stability. The weight of the float body itself pulls the copper rod, thereby achieving rapid inflation and deflation.
[0007] Preferably, it also includes an internal thread cap, a vent hole, and a chamfered portion. The internal thread cap is provided with a vent hole, and the valve core output end is provided with an external thread portion. The internal thread cap is threadedly connected to the external thread portion. When the internal thread cap rotates, so that the vent hole is away from the valve core, the air discharged from the valve core is discharged through the vent hole, thereby improving flexibility.
[0008] Preferably, it also includes a chamfered portion, wherein the valve core output end is provided with a chamfered portion; the internal thread cap is quickly fitted onto the valve core output end with the cooperation of the chamfered portion and is threadedly connected to the external threaded portion.
[0009] Preferably, it also includes an annular groove, and the valve core output end is provided with an annular groove; after a period of use, the spring and sealing gasket will age, and water will be released along with the venting. The internal thread cap will seal the valve core, and the water pipe will be fitted onto the valve core output end. The wire will be used to bind the water pipe with the cooperation of the annular groove, so that the gas and some water can be discharged together.
[0010] Preferably, it also includes anti-slip protrusions, and multiple sets of anti-slip protrusions are provided on the outer side wall of the internal thread cap; the operator can rotate the internal thread cap by using the anti-slip protrusions to reduce the occurrence of slipping.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, water enters the lower valve body and the upper valve body through the inlet. The exhaust assembly keeps the upper valve body input end sealed. When water and air enter the lower valve body and the upper valve body, the air pressure will cause the float assembly to drop, thereby releasing the seal of the exhaust assembly on the valve core input end, allowing the air to be discharged through the valve core. When water re-enters the lower valve body and the upper valve body, the exhaust assembly re-seals the valve core input end, improving convenience. Attached Figure Description

When air enters the lower valve body 1 and the upper valve body 4, the float body 10 descends, causing the copper rod 7 to tilt, further releasing the seal of the sealing gasket 9 on the inside of the valve core 5, allowing air to be discharged through the valve core 5. When water re-enters the lower valve body 1 and the upper valve body 4, the float body 10 floats up, and the top of the float body 10 contacts the top of the inside of the upper valve body 4. The spring 6 returns to a horizontal state, thereby resealing the sealing gasket 9 on the input end of the valve core 5.
[0024] Example 2
[0025] like Figures 1 to 5 As shown, the exhaust valve of this utility model includes a lower valve body 1, a bracket 2, a positioning pin 3, an upper valve body 4, and a valve core 5.

[0026] like Figure 5 As shown, it includes a spring 6, a copper rod 7, a round cap 8, and a sealing gasket 9. The first end of the spring 6 is fitted on the outside of the output end of the upper valve body 4, and the second end of the spring 6 is fitted on the first end of the copper rod 7.

When air enters the lower valve body 1 and the upper valve body 4, the float body 10 descends, causing the copper rod 7 to tilt, further releasing the seal of the sealing gasket 9 on the inside of the valve core 5, allowing air to be discharged through the valve core 5. When water re-enters the lower valve body 1 and the upper valve body 4, the float body 10 floats up. The top of 10 contacts the inner top of the upper valve body 4, and the spring 6 returns to a horizontal state, thereby resealing the sealing gasket 9 against the input end of the valve core 5. The internal thread cap 14 is threadedly connected to the external thread. When the internal thread cap 14 rotates, the vent hole 15 moves away from the valve core 5, and the gas discharged from the valve core 5 is discharged through the vent hole 15.
