And simultaneously, when the pressure difference at two sides is smaller than a set value, the valve is automatically closed to ensure medium partition at two sides.

Description

Automatic partition device of two-way seal

Technical Field

The utility model belongs to the technical field of valves, and particularly relates to a bidirectional sealing automatic partition device.

Background

The desulfurization ash discharged by the boiler dust remover at regular intervals is stored to a certain amount by an ash bin, and then is sucked out by a suction and discharge vehicle through an ash conveying pipeline by connecting an ash conveying pipeline at the bottom of the ash bin by personnel for transportation. Meanwhile, air flows into the ash bin from a breathing port at the top of the ash bin, so that no pressure difference exists between the ash bin and the outside to prevent the ash bin from deforming. When the pressure air assisted blowing is started, the breathing port discharges air outwards to ensure that the ash bin is pressureless and prevent the ash bin from deforming. Meanwhile, the desulfurization ash has the characteristic of moisture absorption, the ash in the desulfurization ash tank is easy to harden due to moisture absorption in the ash bin storage process, and the ash is not smooth to put, so that the desulfurization ash is very important to isolate with air in storage, and the air cannot be isolated by installing a conventional valve due to the fact that the suction port is large, the method adopted at present is to use a blind plate for air isolation, and the blind plate is detached for suction and discharge during suction and discharge of the desulfurization ash, so that the operation is complicated.

The patent of application number 201821782309.0 discloses a two-way block valve, and the valve of this patent can safe and reliable cuts off pipeline through setting up the case that has two valve plates, cuts off the circulation medium tightly, utilizes the cavity between two valve plates to fill inert gas or the isolated circulation medium of liquid, makes the staff can be safe and secure to pipe network and equipment overhauls transformation, guarantees people's life safety. The utility model has high safety, good environmental protection and reliable operation. This patent suffers from the following disadvantages: when the valve is cut off, inert gas or liquid needs to be filled, the valve is suitable for a working scene with large cut-off pressure, automatic opening cannot be realized, and the valve can be opened after the filled inert gas or liquid needs to be released.

Disclosure of Invention

The utility model aims to provide a bidirectional sealing automatic partition device which can automatically open a valve when desulfurization ash is sucked and discharged and automatically close the valve after the suction and the discharge are finished so as to solve the problems in the prior art.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a two-way sealed automatic partition device, includes the valve body, and the welding of valve body both ends has the holder, and the holder at valve body both ends passes through the guide bar to be connected, and the guide bar cross-under has the valve plate, and the valve plate both sides are equipped with the spring and cup joint on the guide bar, are equipped with the sealing block in the valve body.

Further, the valve plate has the same diameter as the inner diameter of the sealing block.

Further, both ends of the spring are respectively propped against the retainer and the valve plate, and the spring is in a compressed state after being installed.

Further, a through hole is formed in the center of the valve plate, and the guide rod is connected with the valve plate in a penetrating mode through the through hole.

Further, a plurality of breathing holes are arranged on the retainer.

The utility model has the following beneficial effects:

1. when the desulfurization ash is sucked and discharged, the pressure on one side of the ash bin is large, and the valve plate is ejected out of the sealing block, so that the valve is automatically opened to suck and discharge, a blind plate is not required to be detached, the suction and discharge efficiency is improved, and the labor investment is saved.

2. After the desulfurization ash is sucked and discharged, the pressure on two sides of the valve plate tends to be balanced, and the valve plate returns to the sealing block, so that the valve is automatically closed, a blind plate is not required to be installed manually, the input of manpower is further saved, and the workload is reduced.

3. The utility model can be applied to unidirectional cut-off automatic switching, also can be applied to bidirectional cut-off, and can automatically suck/exhaust when the pressure at two sides exceeds the set upper limit of the container so as to ensure that the container is not over-pressurized, thereby realizing bidirectional automatic transportation of materials/media. And simultaneously, when the pressure difference at two sides is smaller than a set value, the valve is automatically closed to ensure medium partition at two sides.

Detailed Description

The utility model will now be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-3, the bidirectional sealing automatic partition device comprises a valve body 1, wherein retainers 2 are welded at two ends of the valve body 1, the retainers 2 at two ends of the valve body 1 are connected through guide rods 3, the guide rods 3 are connected with valve plates 4 in a penetrating manner, springs 5 are arranged at two sides of the valve plates 4 and are sleeved on the guide rods 3, and sealing blocks 6 are arranged in the valve body 1. The valve plate 4 has the same diameter as the inner diameter of the seal block 6. Both ends of the spring 5 are respectively propped against the retainer 2 and the valve plate 4, and the spring 5 is in a compressed state after being installed.
