Description

Technical Field

[0001] The present invention belongs to the technical field of valves, and in particular relates to a deepwater valve device. Background Art

[0002] When two adjacent pools are in use, they are sometimes connected and sometimes used independently. This requires installing valves near the bottom of the pool. If common valves that use rotary motion to open and close are used, operation is very difficult when the pool is deep.

[0003] At the same time, in water treatment processes using mobile sand filters and mobile activated carbon adsorption tanks, the filter media at the bottom of the tank needs to be transported to the top of the tank for cleaning by airlift. The current practice is to equip each tank with a separate pneumatic conveying pipeline. However, this installation method requires a large number of pipes and valves, resulting in a large equipment investment. Moreover, each tank is only cleaned for 1-2 hours per day, which means that the pipeline is idle most of the time, with extremely low utilization rate. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems and provide a deep water valve device which is easy to operate and can complete opening and closing actions in the vertical direction.

[0005] To this end, the technical solution of the present invention is: a deepwater valve device, characterized in that: it includes a deepwater valve and a top pipe, the deepwater valve includes an upper valve chamber, a mounting plate and a lower valve chamber, a conical guide tube is installed at the upper end of the upper valve chamber, and the lower end of the lower valve chamber is the inlet end; the mounting plate is placed between the upper and lower valve chambers, and a piston cylinder is fixed on the mounting plate, a piston that can move relative to the piston cylinder is provided in the piston cylinder, a sealing block is provided at the top of the piston, the sealing block is sealed with the pipe mouth of the guide tube, and a spring is provided between the piston and the piston cylinder; a feed port is provided on the side of the lower end of the top pipe, the top pipe is inserted into the upper valve chamber from the guide tube, and presses down the piston, and the inlet end of the lower valve chamber is connected to the feed port of the top pipe.

[0006] Preferably, the spring is in a compressed state, and the sealing block at the top of the piston is in sealing cooperation with the pipe opening of the guide tube.

[0007] Preferably, the mounting plate is a hollow structure on all sides, with a piston cylinder installed in the middle.

[0008] Preferably, a sealing tube is provided above the guide tube, a conical guide block is provided above the feed port of the top tube, and a sealing ring is provided on the guide block. When the top tube is inserted into the upper valve cavity from the guide tube, the sealing ring on the guide block fits tightly with the sealing tube.

[0009] When the valve is closed, the spring is in a compressed state. The elastic force given by the spring causes the sealing block at the top of the piston to be tightly pressed against the orifice of the guide tube, so that the entire valve is in a closed state.

[0010] The valve is opened, and the push pipe is inserted into the upper valve cavity from the sealing pipe and the guide pipe. The push pipe presses down the piston, so that the sealing block at the top of the piston is separated from the pipe mouth of the guide pipe, thereby connecting the inlet end of the lower valve cavity with the push pipe.

[0011] Deepwater valves are used in conjunction with jacking pipes. Depending on different usage scenarios, each valve body can be equipped with a jacking pipe, or multiple valve bodies only need to be equipped with one jacking pipe, that is, the jacking pipes are shared, thereby reducing costs.

[0012] The opening and closing actions of the deep-water valve described in the present invention are all completed in the vertical direction, and the operation is simple; it can be used in water treatment processes of mobile sand filters and mobile activated carbon adsorption tanks. Each water tank is equipped with a deep-water valve, and the pneumatic conveying pipeline connected to the deep-water valve is set to be shared. The lifting mechanism and the mobile platform are used to reciprocate between multiple tanks, which can greatly reduce pipeline configuration and reduce pipeline idle time.

DETAILED DESCRIPTION

[0021] See the accompanying drawings. The deepwater valve 20 described in this embodiment is divided into two parts, the upper half of the valve consisting of a sealing tube 1, a guide tube 2, and an upper valve chamber 3. The upper end of the upper valve chamber 3 has an opening, fixedly mounted at the opening with a tapered guide tube 2, and a sealing tube 1 disposed above the guide tube 2. The lower half consists of a mounting plate 4, a lower valve chamber 5, a reducing tube 6, and a feed inlet flange 7. The reducing tube 6 is mounted at the lower end of the lower valve chamber 5, and the feed inlet flange 7 is mounted at the bottom of the reducing tube.

[0022] The mounting plate 4 is placed between the upper and lower valve chambers. The mounting plate 4 is surrounded by a hollow structure 41, and a piston cylinder 8 is installed in the middle. The piston cylinder 8 is a hollow cylindrical structure, and a piston 9 that can move relative to the piston cylinder is provided inside. A sealing block 10 is provided on the top of the piston 9; a spring 11 is provided between the piston 9 and the piston cylinder 8, and the spring 11 is in a compressed state. The sealing block 10 on the top of the piston is sealed with the pipe mouth of the guide tube 2.

[0023] The first jacking pipe 12 is provided with an inlet 121 and an outlet 122 on its side, connecting the two pools from the bottom. To use the first jacking pipe, insert the inlet end of the first jacking pipe through the guide tube into the upper valve cavity and press down on the piston to open the deep-water valve. Water enters through the feed flange, passes through the lower valve cavity, the hollow structure around the mounting plate, and the upper valve cavity, flows into the first jacking pipe's inlet hole, and then flows upward out of the outlet hole.

[0024] like Figure 8 As shown, the deep water valve 20 can be used in the water treatment process of the mobile sand filter and the mobile activated carbon adsorption tank. Each water tank 19 is equipped with a deep water valve 20, and the pneumatic conveying pipeline 18 connected to the deep water valve is set to be shared, and the lifting mechanism and the mobile platform are used to reciprocate between multiple tanks.

[0025] The second top pipe 13 is used to transport water or a mixture of solids and water to the outside of the pool. A feed port 14 is provided on the side of the lower end of the second top pipe, and a conical guide block 15 is provided above the feed port, and a sealing ring 16 is provided on the guide block; a check air inlet valve 17 and a pneumatic conveying pipeline 18 are installed above the second top pipe 13.

[0026] When the second jacking pipe 13 is in use, it moves downward in the center of the system under the action of the guide block 15 on the second jacking pipe. The sealing ring 16 installed on the guide block enters the sealing pipe 1 of the deepwater valve, completing the sealed connection between the deepwater valve, the second jacking pipe, and the pneumatic conveying pipe. The second jacking pipe 13 continues to move downward, reaching the top of the piston 9 and continuing to press down, connecting the upper and lower parts of the valve. When the air inlet of the pneumatic conveying pipeline 18 is opened, the water in the second jacking pipe 13 is transported away, causing the liquid level in the second jacking pipe to be much lower than the liquid level in the water tank 19. Due to the liquid level difference, the water and materials in the pool flow into the second jacking pipe through the deepwater valve and are then pneumatically conveyed to the top of the pool.

[0027] When closing the valve, the second top pipe 13 is lifted upward, and the piston 9 moves upward under the action of the spring 11, pressing the sealing block 10 on the top of the piston against the pipe mouth of the guide pipe 2, thus completing the closing of the valve.
