Description

Technical Field

[0001] This utility model relates to the field of exhaust valve technology, and in particular to a staged pressure boosting exhaust valve. Background Technology

[0002] Air venting valves are used for venting pipes in independent heating systems, centralized heating systems, heating boilers, central air conditioning, floor heating, and solar heating systems. Because water usually contains a certain amount of dissolved air, and the solubility of air decreases as the temperature rises, gas gradually separates from the water during the water circulation process and gradually gathers together to form large bubbles or even air columns. Because of the replenishment of water, gas is often generated. When the pressure in the pressure chamber is less than the pressure in the exhaust chamber, the valve opens to release the gas. Pressure boosting air venting valves usually have the characteristics of rapid opening and closing.

[0003] Currently, existing exhaust valves have certain limitations in pressure control. In actual use, it is difficult to easily adjust different levels of pressure, it is difficult to guarantee the effect of graded pressurization, and the flexibility is poor, making it difficult to meet the specific needs of the system.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: This example is used to solve the problem that existing exhaust valves are difficult to adjust pressure at different levels in actual use, are difficult to guarantee the effect of graded pressurization, have poor flexibility, and are difficult to meet the specific needs of the system.

[0025] Please see Figure 1 - Figure 5 As shown, this embodiment is a staged pressurization exhaust valve, including a valve body shell 1, a sealing seat 3 fixedly installed on the upper surface of the valve body shell 1, a discharge cylinder 12 that is penetrated and fixedly connected to the upper surface of the sealing seat 3, a flange joint 2 provided at the bottom end of the valve body shell 1, a movable rod 9 movably installed inside the sealing seat 3, a float ball 10 fixedly installed at the end of the movable rod 9, a push rod 11 that cooperates with the float ball 10 provided inside the valve body shell 1, and an adjustment mechanism provided inside the valve body shell 1;

[0026] The regulating mechanism includes a vertically sliding movable seat 7 located inside the valve body housing 1. A movable connector 8, which is movably connected to a movable rod 9, is fixedly connected to the lower surface of the movable seat 7. An installation sleeve 4 is fixedly connected to the sealing seat 3. A screw 18 is rotatably connected through and limited by the installation sleeve 4. The screw 18 passes through the movable seat 7 and is screwed to the movable seat 7. Two symmetrically arranged limiting rods 19 are fixedly connected to the lower surface of the sealing seat 3. The two symmetrically arranged limiting rods 19 pass through the movable seat 7 and are vertically limited and slidably connected to the movable seat 7.

[0027] When the screw 18 is rotated, it pushes the movable seat 7 to move vertically. The vertical movement of the movable seat 7 causes the movable seat 7, the movable rod 9, and the float 10 to move vertically downward as a whole, thereby enabling graded adjustment. When the liquid pushes the float 10 to make the movable rod 9 contact the push rod 11, more liquid is needed. Through the screw-connection design between the screw 18 and the movable seat 7 in the adjustment mechanism, the overall position of the float 10 and the movable rod 9 can be precisely adjusted, allowing the exhaust valve to achieve different levels of pressure adjustment according to system requirements. When more liquid is needed to push the float 10 to trigger the exhaust, simply rotating the screw 18 can achieve the effect of graded pressurization.

[0028] The push rod 11 passes through the discharge cylinder 12 and is vertically slidably connected to the discharge cylinder 12. A sealing plate 13 is fixedly connected to the outer wall of the push rod 11 inside the discharge cylinder 12. There is a gap between the sealing plate 13 and the inner wall of the discharge cylinder 12 for gas discharge. A partition plate 15 is fixedly connected to the inner wall of the discharge cylinder 12. A spring 14 is sleeved on the outer wall of the push rod 11 and abuts against the partition plate 15 and the sealing plate 13. Exhaust ports are opened on the lower surface of the discharge cylinder 12 and the surface of the partition plate 15.

[0029] When the flange joint 2 is connected to the liquid pipeline, the liquid moves into the valve body shell 1. Under the buoyancy of the liquid, the float 10 drives the movable rod 9 to move. The movable rod 9 contacts the bottom end of the push rod 11, thereby pushing the push rod 11 to move vertically upward. At this time, the sealing plate 13 overcomes the elastic force of the spring 14 and separates from the exhaust port at the bottom of the discharge cylinder 12, allowing the gas in the valve body shell 1 to be discharged through the exhaust port on the partition plate 15.

[0030] A limiting block 20 is fixedly connected to the inner wall of the valve body shell 1. A sliding block 21 is fixedly connected to the side of the movable seat 7 near the limiting block 20. A sliding groove is opened on the surface of the limiting block 20 to slide vertically with the sliding block 21. By limiting the sliding block 21 through the limiting block 20, the vertical direction of the movable seat 7 can be further limited, ensuring that the movable seat 7 moves stably in the vertical direction.

[0031] The upper surface of the mounting sleeve 4 is fixedly connected to the sealing cover 5. A cavity is provided between the mounting sleeve 4 and the sealing cover 5. The end of the screw 18 located inside the mounting sleeve 4 and the sealing cover 5 is provided with a keyway. By inserting a corresponding tool into the keyway, the screw 18 can be rotated to adjust the position of the moving seat 7 in the vertical direction.

[0032] Two connecting posts 16 located on both sides of the discharge cylinder 12 are fixedly connected to the upper surface of the sealing seat 3. A baffle 17 is fixedly connected to the upper surface of the two connecting posts 16. The baffle 17 is used to block the top of the connecting posts 16 to prevent foreign objects from falling into the discharge cylinder 12 and causing blockage.

[0033] Example 2: This example is used to solve the problem of how to reduce the damage caused by impurities and solid particles in liquid to the components inside the exhaust valve.

[0034] Please see Figure 1 - Figure 5 As shown in the figure, in a staged pressure boosting exhaust valve of this embodiment, a filter cylinder 6 is embedded in the bottom opening of the flange joint 2. The surface of the filter cylinder 6 is provided with uniformly distributed filter holes. By setting the filter cylinder 6, impurities and solid particles in the water can be removed, reducing the impact of impurities and solid particles on the exhaust valve.

[0035] Combining Embodiments 1 and 2, by setting an adjustment mechanism, rotating the corresponding screw 18 can precisely adjust the overall position of the float 10 and the movable rod 9, enabling the exhaust valve to achieve different levels of pressure adjustment according to system requirements, thus providing high flexibility. When more liquid is needed to push the float 10 to trigger exhaust, simply rotating the screw 18 can achieve a graded pressurization effect. The opening pressure of the exhaust valve can be precisely controlled by adjusting the position of the movable seat 7, thereby meeting the specific needs of the system. The surface of the filter cylinder 6 is provided with uniformly distributed filter holes. By setting the filter cylinder 6, impurities and solid particles in the liquid can be removed, ensuring that the liquid entering the exhaust valve is relatively pure and reducing the risk of impurities and solid particles causing wear or blockage to the internal components of the exhaust valve.
