Description

Technical Field

[0001] The present invention relates to the technical field of valves, in particular to an anti-drip valve. Background Art

[0002] Sewage treatment is an important part of the environmental protection field. With the rapid development of the domestic economy and the improvement of residents' living standards, the annual discharge of industrial and domestic sewage is also increasing. The production capacity of my country's sewage treatment market is expanding rapidly, and the daily sewage treatment capacity is showing an increasing trend year by year. The total amount of sewage drainage pipes is also increasing. The valves on the corresponding pipes are used as control components in the sewage transportation system.

[0003] The current valve has certain deficiencies when in use:

[0004] 1. When using existing valves, the valve stem is usually used to seal the aperture to control the flow and closing of water. The general valve only has one sealing measure, which will lead to aging of the blockage over the years, and the seal is not tight enough, resulting in leakage.

[0005] 2. At the same time, when rotating the valve stem, it is sometimes difficult to rotate during use. It requires a lot of force. Uneven force will produce a horizontal thrust on the valve stem. Over time, it will cause the valve stem to deviate and a gap will appear between it and the valve body. At the same time, the thread is immersed in water for a long time, and a large amount of impurities will accumulate inside the thread, increasing the difficulty of rotation.

[0006] 3. When the valve leaks, it cannot effectively block the water flow, and it is generally difficult for people to find it, causing the water to drip continuously. This not only easily leads to a waste of water resources, but also fails to remind people in time when it leaks. Summary of the Invention

[0007] The purpose of the present invention is to provide a drip-proof valve to solve the problem proposed in the above background technology that the existing valve sealing measures are simple and prone to leakage; at the same time, when the valve stem is rotated, it is easy to cause the valve stem to tilt, and a gap will appear between the valve body; and it is difficult to detect the valve leakage in time, resulting in the waste of water resources.

A sealing plug is provided at the bottom of the first spring. A fixing hole is provided on one side of the two groups of sealing plugs close to each other. The fixing rod is adapted to the fixing hole. A sealing ring is provided on the top of the baffle.

[0010] Preferably, the alarm assembly includes a collecting bin, a contact, a drain hole, a first connecting rod, a drain pipe, a collecting hole and a limiting ring. The collecting bin is located at the edge of the middle position of the bottom inside the valve body, collecting holes are provided on both sides of the top of the collecting bin, contacts are provided on both sides of the top inside the collecting bin, a limiting ring is provided at the edge of the top of the collecting bin, a drain pipe is slidingly provided at the bottom of the collecting bin, a first connecting rod is provided at the bottom of the two groups of drain pipes, and drain holes are provided on the tops of both sides of the drain pipes.

[0019] 1. The present invention can simultaneously block the hole of the partition by the baffle when the second threaded rod is rotated to drive the plug to seal the partition. The sealing ring and the sealing groove are firmly sealed, so that an additional sealing measure is added when the valve is used. The sealing effect is better when the valve is used. The two sealing measures can be carried out at the same time without increasing the additional sealing time, which is more convenient.

[0020] 2. The present invention utilizes a limiting sleeve wrapped around the outside of the second threaded rod to effectively limit the second threaded rod, so that the second threaded rod always moves up and down in the vertical direction. The setting can ensure that the second threaded rod will not be affected by the main force when moving, and will not cause wear to the thread. The two sets of picking pins are stuck inside the thread groove to remove impurities inside the groove and prevent impurities from generating resistance to the movement of the second threaded rod.

[0021] 3. The present invention can collect the dripping water droplets through the collection bin when the valve is sealed, so that the water flow is gathered inside the collection bin. When the water level is at the contact point, the two sets of contacts will be energized to form a circuit, and the external alarm will be opened in time to remind employees that the valve is leaking.

[0033] As a preferred solution of this embodiment: the valve stem 6 and the telescopic rod 201 are rectangular when viewed from above, and the valve stem 6 and the telescopic rod 201 are respectively adapted to the second threaded rod 8 and the first threaded rod 202, so that the valve stem 6 and the telescopic rod 201 can drive the second threaded rod 8 and the first threaded rod 202 to rotate.

[0034] As a preferred solution of this embodiment: a rubber plug is provided on the top of the drain pipe 305 to prevent water from flowing out of the drain pipe 305 .

[0035] As a preferred solution of this embodiment, the top and bottom portions of the fixing rod 14 and the extrusion block 15 close to each other are both inclined, so that the fixing rod 14 and the extrusion block 15 can move horizontally.

[0036] As a preferred solution of this embodiment: through holes are provided on both sides of the interior of the baffle 203 , and the top of the limiting rod 11 is adapted to the through holes, so that the baffle 203 can move vertically upward.

[0037] As a preferred solution of this embodiment, the picking needle 17 is tapered close to the second threaded rod 8 and extends into the thread groove on the second threaded rod 8, so as to facilitate the removal of impurities inside the thread groove.

[0038] As a preferred solution of this embodiment: the inner side of the limiting ring 307 is inclined, and the collecting hole 306 is located inside the limiting ring 307, which is convenient for collecting water droplets.

[0039] As a preferred solution of this embodiment: flanges are provided on both sides of the valve body 1 to facilitate installation of the valve body 1.

[0040] Example 1, as Figure 1-3 As shown, when the valve body 1 is used, the rotating valve stem 6 drives the second threaded rod 8 under the action of the threaded hole 7, so that the second threaded rod 8 drives the plug 9 to move downward, and the first sealing is performed on the partition 4. At the same time, when the plug 9 rotates, the telescopic rod 201 drives the first threaded rod 202 to rotate. The first threaded rod 202 moves the baffle 203 upward through the action of the thread, so that the baffle 203 drives the sealing ring 206 to move toward the inside of the sealing groove 10, so that the baffle 203 tightly seals the bottom of the partition 4, completing the second sealing, and improving the sealing effect of the valve;

[0041] At the same time, as the baffle 203 moves upward, the baffle 203 slides on the outside of the two sets of limit rods 11, and the baffle 203 contacts the extrusion block 15. Since the bottom of the extrusion block 15 is inclined, it pushes the extrusion block 15 toward the inside of the limit rod 11. The extrusion block 15 drives the fixing rod 14 to move out from the inside of the fixing hole 205 through the second connecting rod 13. At this time, the fixing hole 205 falls off from the inside of the collecting hole 306 under the pulling force of the first spring 207, and the collecting bin 301 is opened to facilitate the collection of water droplets.

[0042] Example 2, as Figure 4-5 As shown, when the valve leaks, water droplets drip along the baffle 203 onto the limiting ring 307. Under the action of the limiting ring 307, the water drops flow into the interior of the collecting bin 301 through the collecting hole 306. The water flow inside the collecting bin 301 gathers more and more, and gradually the water flow contacts the two sets of contacts 302, so that the two sets of contacts 302 form a loop, thereby issuing an alarm in time to remind employees that there is a water leak.

[0043] Working principle: First, when the valve body 1 is used, the rotating valve stem 6 drives the second threaded rod 8 to move downward under the action of the threaded hole 7, so that the second threaded rod 8 drives the plug 9 to move downward, and performs the first sealing on the partition 4. At the same time, when the plug 9 rotates, the telescopic rod 201 drives the first threaded rod 202 to rotate. The first threaded rod 202 moves the baffle 203 upward through the action of the thread, so that the baffle 203 drives the sealing ring 206 to move toward the inside of the sealing groove 10, so that the baffle 203 tightly seals the bottom of the partition 4, completing the second sealing and improving the sealing effect of the valve;

[0044] At the same time, as the baffle 203 moves upward, the baffle 203 slides outside the two sets of limit rods 11, and the baffle 203 contacts the extrusion block 15, pushing the extrusion block 15 toward the inside of the limit rod 11. The extrusion block 15 drives the fixing rod 14 to move out of the fixing hole 205 through the second connecting rod 13. At this time, the fixing hole 205 falls off from the inside of the collection hole 306 under the pulling force of the first spring 207, opening the collection bin 301 to facilitate the collection of water droplets.

[0045] When the valve leaks, water droplets drip along the baffle 203 onto the limiting ring 307. Under the action of the limiting ring 307, the water drops flow into the interior of the collecting bin 301 through the collecting hole 306. The water flow inside the collecting bin 301 gathers more and more, and gradually the water flow contacts the two sets of contacts 302, so that the two sets of contacts 302 form a loop, thereby issuing an alarm in time to remind employees that there is a water leak.

[0046] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
