Description

Technical Field

[0001] The utility model relates to the technical field of sewage collection, and more specifically, to an anti-blocking high-level water float valve. Background Technique

[0002] The liquid level floating ball valve is mainly used in the sewage negative pressure collection system to control the switch of the negative pressure pipe connected to the collection bucket. At present, the liquid level floating ball valves on the market mainly rely on the pressure difference between the negative pressure in the negative pressure pipe and the normal pressure in the bucket to provide power.

[0003] A high-level water float check valve in the prior art (publication number: CN219911957U), which consists of a negative pressure pipeline, a limit filter pipe and a floating ball, changes the complex negative pressure valve that relies on the pressure difference to provide power into a high-level water float switch that relies on the buoyancy of water to control the switch compared with the traditional liquid level floating ball valve group, reducing the manufacturing cost and improving the reliability.

[0004] However, in the process of using the current high-level water float check valve, the following problems have also been found:

[0005] 1. The filter mesh holes on the valve body are easy to enter the waste paper discarded by users, especially the homework paper of students. After drying, it solidifies on the filter wire mesh and inside the valve body, seriously affecting the up and down movement of the floating ball in the valve body;

[0006] 2. Due to the large amount of grease in the kitchen wastewater, it is easy to form sludge adhesion on the inner wall of the valve body, which again affects the up and down movement of the floating ball.

[0007] In view of this, we propose an anti-blocking high-level water float valve. Content of the Utility Model

[0008] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide an anti-blocking high-level water float valve to solve the technical problem that the filter mesh holes on the current high-level water float check valve are easy to enter the waste paper discarded by users, dry and solidify on the filter wire mesh and inside the valve body, and cooperate with the sludge adhesion formed by grease on the inner wall of the valve body to affect the up and down movement of the floating ball.

[0009] To solve the above technical problems, the utility model provides the following technical solution: an anti-blocking high-level water float valve, including a filter valve body;

[0010] A diversion cavity is opened in the filter valve body, and a hollow floating ball is floatingly arranged in the diversion cavity. Two water inlets communicating with the diversion cavity are symmetrically opened at the low position of the hollow floating ball on the outer edge surface of the filter valve body, and a ventilation hole communicating with the diversion cavity is centrally opened at the high position of the hollow floating ball on the filter valve body;

[0011] The bottom end of the filter valve body is connected to a negative pressure pipe, and an arc-shaped inclined surface matching the arc surface of the hollow floating ball is provided at the bottom end of the filter valve body.

[0012] In the utility model, through the arrangement of the hollow floating ball in the filter valve body, when the water body in the barrel enters the diversion cavity through the two water inlets, the hollow floating ball moves upward under the influence of buoyancy, so that the sewage flows out through the negative pressure pipe. When the hollow floating ball moves upward, the air in the diversion cavity is discharged through the air exchange holes. When the floating ball moves downward, the air enters the diversion cavity through the air exchange holes. Since the diameter of the air exchange holes is small, the air intake volume is less than the discharge volume of the sewage in the diversion cavity, so the effect of slowing down the falling speed of the hollow floating ball can be achieved. When the water surface is lower than the two air exchange holes, the outside air will quickly enter the diversion cavity, making the water surface in the diversion cavity consistent with the outside water surface and accelerating the discharge speed of the sewage. Thus, together with the two enlarged air exchange holes, sundries such as paper sheets are sucked into the negative pressure pipe, improving the sewage discharge ratio while ensuring the discharge effect of the sundries, achieving the effect of preventing blockage, and thus avoiding the problem of hindering the up and down movement of the hollow floating ball.

[0013] Preferably, a gap is left between the hollow floating ball and the inner wall of the diversion cavity, and the sum of the two side gaps is greater than the radius of the hollow floating ball.

[0014] Preferably, the negative pressure pipe includes elbow A, one end of elbow A is connected to the bottom end of the filter valve body, and the other end of elbow A is fixedly connected to a C-shaped pipe.

[0015] Preferably, the C-shaped pipe is connected to elbow B at the end far from elbow A, and a pressure relief micro-hole is centrally opened at the top of one side of the C-shaped pipe.

[0016] Preferably, a valve is fixedly installed on the outer edge surface of elbow B, and a flange is fixedly installed at the end of elbow B far from the C-shaped pipe.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. In the utility model, through the setting of the hollow floating ball in the filter valve body, when the water in the barrel enters the diversion cavity through the two water inlets, the hollow floating ball moves upward under the influence of buoyancy, so that the sewage flows out through the negative pressure pipe. When the hollow floating ball moves upward, the air in the diversion cavity is discharged through the air exchange holes. When the floating ball moves downward, the air enters the diversion cavity through the air exchange holes. Since the diameter of the air exchange holes is small, the air intake volume is less than the sewage discharge volume in the diversion cavity, so the falling speed of the hollow floating ball can be slowed down. When the water surface is lower than the two air exchange holes, the outside air will quickly enter the diversion cavity, making the water surface in the diversion cavity consistent with the outside water surface, accelerating the sewage discharge speed, and thus cooperating with the two enlarged air exchange holes to suck sundries such as paper into the negative pressure pipe, improving the sewage discharge ratio while ensuring the discharge effect of sundries, achieving the anti-blocking effect, and avoiding the problem of hindering the up and down movement of the hollow floating ball.

[0019] 2. In the utility model, by expanding the gap between the hollow floating ball and the inner wall of the filter valve body, when the hollow floating ball moves up and down under the influence of buoyancy, the influence of oil pollution on the hollow floating ball is reduced, and the smoothness of the movement of the hollow floating ball is improved.

[0020] 3. In the utility model, the hollow floating ball also falls on the bottom of the filter valve body to seal the negative pressure pipe. After the sealing is completed, to avoid the problem that the negative pressure in the negative pressure pipe adsorbs the hollow floating ball after the water is discharged, the small air intake holes opened on the C-shaped pipe can provide a small air intake volume. Thus, after the sewage discharge is completed, the air pressure difference between the negative pressure pipe and the outside is gradually balanced, and the release of the hollow floating ball is completed, so that it can move upward again under the influence of buoyancy.

[0026] As Figure 1 shown, a high-position water floating valve with anti-blocking function involved in the utility model includes a filter valve body 1;

[0027] As Figure 1 、 Figure 2, Figure 3 As shown, in the embodiment of the present utility model, to avoid the problem of hindering the up and down movement of the hollow float ball 2, a diversion cavity is provided in the filter valve body 1, and the hollow float ball 2 is floatingly arranged in the diversion cavity. Two water inlets 101 communicating with the diversion cavity are symmetrically arranged at the lower position of the hollow float ball 2 on the outer edge surface of the filter valve body 1, and a ventilation hole 102 communicating with the diversion cavity is centrally arranged at the upper position of the hollow float ball 2 on the filter valve body 1. The bottom end of the filter valve body 1 is connected to a negative pressure pipe, and an arc-shaped inclined surface matching the arc surface of the hollow float ball 2 is provided at the bottom end of the filter valve body 1. Through the setting of the hollow float ball 2 in the filter valve body 1, when the water in the bucket enters the diversion cavity through the two water inlets 101, the hollow float ball 2 moves upward under the influence of buoyancy, so that the sewage flows out through the negative pressure pipe. When the hollow float ball 2 moves upward, the air in the diversion cavity is discharged through the ventilation hole 102, and when the float ball moves downward, the air enters the diversion cavity through the ventilation hole 102. Since the diameter of the ventilation hole 102 is small, its air intake volume is less than the discharge volume of the sewage in the diversion cavity, so the falling speed of the hollow float ball 2 can be slowed down. When the water surface is lower than the two ventilation holes 102, the outside air will quickly enter the diversion cavity, making the water surface in the diversion cavity consistent with the outside water surface, accelerating the sewage discharge speed, and thus sucking sundries such as paper into the negative pressure pipe in cooperation with the two enlarged ventilation holes 102, improving the sewage discharge ratio while ensuring the effect of discharging sundries, achieving an anti-blocking effect, and thus avoiding the problem of hindering the up and down movement of the hollow float ball 2.

[0028] As Figure 1 , Figure 2 As shown, in the embodiment of the present utility model, to improve the smoothness of the movement of the hollow float ball 2, a gap is left between the hollow float ball 2 and the inner wall of the diversion cavity, and the sum of the two side gaps is greater than the radius of the hollow float ball 2. By expanding the gap between the hollow float ball 2 and the inner wall of the filter valve body 1, when the hollow float ball 2 moves up and down under the influence of buoyancy, the influence of oil stains on the hollow float ball 2 is reduced, and the smoothness of the movement of the hollow float ball 2 is improved.

[0029] As Figure 1 , Figure 2 , Figure 3As shown, in the embodiment of the present utility model, to facilitate the upward movement of the hollow floating ball 2 again under the influence of buoyancy, the negative pressure pipe includes an elbow pipe A3. One end of the elbow pipe A3 is connected to the bottom end of the filter valve body 1, and the other end of the elbow pipe A3 is fixedly connected to a C-shaped pipe 4. One end of the C-shaped pipe 4 away from the elbow pipe A3 is connected to an elbow pipe B5. A pressure relief micropore 401 is centrally opened at the top of one side of the C-shaped pipe 4. A valve 6 is fixedly installed on the outer edge surface of the elbow pipe B5, and a flange 7 is fixedly installed at the end of the elbow pipe B5 away from the C-shaped pipe 4. The hollow floating ball 2 falls on the inner bottom of the filter valve body 1 to seal the negative pressure pipe. After sealing, to avoid the problem that the negative pressure in the negative pressure pipe adsorbs the hollow floating ball 2 after the water body is discharged, the pressure relief micropore 401 opened on the C-shaped pipe 4 can provide a small amount of air intake. Thus, after the sewage discharge is completed, the air pressure difference between the negative pressure pipe and the outside is gradually balanced, and the release of the hollow floating ball 2 is completed, so as to facilitate the upward movement again under the influence of buoyancy.

[0030] Working principle: This embodiment provides an anti-blocking high-level water float valve. When in use, a negative pressure device is arranged at one end of the elbow pipe B5, and the valve 6 is opened. The negative pressure device cooperates with the elbow pipe A3, the C-shaped pipe 4, and the elbow pipe B5 to extract the sewage in the barrel. The sewage enters the filter valve body 1 through the two water inlets 101 and is discharged through the elbow pipe A3, the C-shaped pipe 4, and the elbow pipe B5. When discharging the sewage, the hollow floating ball 2 in the filter valve body 1 is affected by the low air intake volume of the air exchange hole 102, resulting in the water level in the filter valve body 1 being higher than the water level in the barrel, increasing the proportion of sewage discharged. When the water level in the barrel reaches the two water inlets 101, a large amount of air enters the filter valve body 1, making the water level in the filter valve body 1 consistent with the water level in the barrel, increasing the sewage discharge speed. Paper scraps and other sundries are sucked into the negative pressure pipe and discharged, so that the hollow floating ball 2 falls into the arc-shaped inclined plane at the inner bottom of the filter valve body 1 to complete the sealing of the filter valve body 1. After sealing, air slowly enters the C-shaped pipe 4 through the pressure relief micropore 401 to gradually balance the pressure difference between the negative pressure pipe and the outside, reducing the suction force of the negative pressure pipe on the hollow floating ball 2, so as to facilitate the upward movement of the hollow floating ball 2 again under the influence of the buoyancy of the sewage entering the filter valve body 1, which is convenient to use.

[0031] The embodiments disclosed in the present utility model are preferred embodiments, but are not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present utility model according to the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
