Description

But automatically regulated's tee bend device

Technical Field

The utility model belongs to there is the liquid circulation system control field of gaseous production, especially relates to a tee bend device according to liquid air entrainment volume automatically regulated for the electrolyte circulation control system of aluminium silver oxide battery.

Background

The aluminum silver oxide battery can generate hydrogen in the working process, and the hydrogen needs to be separated and discharged through an electrolyte circulating system. However, the gas production rate of the battery is affected by temperature, electrolyte concentration and the like, and the gas-liquid separation effect is affected by the motion state (such as floating, submergence, turning and the like), so that under extremely severe environmental conditions, the phenomenon that gas cannot be separated completely in time and enters a centrifugal pump along with return water to cause pump cavitation can occur, and the whole electrolyte circulation system is broken down.

In order to solve the problem of backwater air-entrainment pump-in phenomenon under the condition of small probability, a method for increasing the exhaust capacity of an electrolyte circulating system is generally adopted, but the volume and the weight of each system part are increased, and the liquid discharge carried by the exhaust is increased; the other method is to control the opening and closing of the three-way device by a controller by detecting the condition of backwater and air entrainment, and the method is complex and needs to be provided with an additional controller and a detector.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming these shortcomings, provide a three-way device according to liquid presss from both sides tolerance automatically regulated.

In order to achieve the above object, the utility model provides a technical scheme that its technical problem adopted is: the utility model provides a but three-way device of automatically regulated, includes protects a section of thick bamboo and sets up valve body and case in protecting a section of thick bamboo, the valve body on be provided with horizontal water inlet and delivery port respectively, be provided with the sealing washer between the case outside and protecting a section of thick bamboo, the bottom of protecting a section of thick bamboo is provided with the return water mouth with water inlet and delivery port intercommunication, the top blind end of protecting a section of thick bamboo is provided with permanent magnet one, permanent magnet below has set gradually fixes the permanent magnet on the case top and overlaps the permanent magnet three of establishing on the case, permanent magnet one and permanent magnet two between be the repulsion, permanent magnet two and permanent magnet three between.

The surface roughness Ra of the contact surfaces of the valve core and the valve body of the three-way device capable of being automatically adjusted is not more than 1.6 mu m.

The utility model has the advantages that: the utility model discloses after utilizing liquid to smuggle gas secretly, its thrust to the case production changes, has designed the magnetic force with its equilibrium for this tee bend device can carry out automatically regulated according to return water air entrainment volume. Under the non-working state, the water inlet is opened, and the water return port is closed; under the normal working state, the backwater reaches the backwater port and generates certain pressure to push the valve core to overcome the suction force between the permanent magnet II and the permanent magnet III, so that the backwater port is opened and the water inlet is closed; when the backwater is carried with gas, the thrust generated by the backwater to the valve core is reduced, the valve core moves downwards and reaches new balance with the magnetic force applied to the permanent magnet II, at the moment, the opening degree of the backwater port is reduced, and the opening degree of the water inlet is correspondingly increased. The utility model discloses a water inlet and return water mouth aperture size and how much relevant of return water air entrainment volume. The utility model discloses simple structure is compact, and the action is reliable, changes the instant response to return water air entrainment volume.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Fig. 1, 2 and 3 are schematic structural diagrams in different working states. The position of the valve core 7 determines the distribution ratio of the inlet water and the return water.

The utility model discloses a but automatically regulated's tee bend device, including protecting a section of thick bamboo 2 and setting valve body 5 and case 7 protecting in a section of thick bamboo 2, valve body 5 on be provided with horizontal water inlet and delivery port respectively, case 7 with protect and be provided with sealing washer 6 between a section of thick bamboo 2, the bottom of protecting a section of thick bamboo 2 is provided with the return water mouth with water inlet and delivery port intercommunication, the top blind end that protects a section of thick bamboo 2 is provided with permanent magnet one 1, permanent magnet one 1 below has set gradually and has fixed permanent magnet two 3 on 7 tops of case and cover establish permanent magnet three 4 on case 7, permanent magnet one 1 and permanent magnet two 3 between be the repulsion, permanent magnet two 3 and permanent magnet three 4 between be suction.

Wherein the surface roughness Ra of each contact surface of the valve core 7 and the valve body 5 is not more than 1.6 μm.

Two 3 and case 7 of permanent magnet link to each other and constitute the utility model discloses a movable assembly, and the magnetic force that two 3 of permanent magnets received reaches dynamic balance with the thrust that the return water produced, realizes carrying out the function of automatically regulated water inlet and return water mouth aperture according to return water air entrainment volume.

Fig. 5 is a typical application scenario of the present invention. The working process of the present invention is further described below with reference to fig. 5:

in the initial stage of work, the water inlet is opened, the water return port is closed, and liquid enters the electrolyte circulating system. Along with annotating the increase of liquid volume, the system internal pressure risees, and until being greater than the magnetic force that two 3 of permanent magnets received, case 7 moves up, and return water mouth flow accounts for the overwhelming majority of whole flow, and water inlet liquid only flows through the gap between case 7 and the valve body 5, this moment the utility model discloses a flow distribution relation is the distribution proportion when horizontal axis is zero in seeing fig. 4.

When the gas production rate of the circulating system is large or the gas is not completely separated, and part of gas is clamped in the water return port, the thrust generated by the liquid in the water return port on the valve core 7 can be reduced, the valve core 7 can move downwards (as shown in a schematic diagram in fig. 3) in order to achieve a state of equilibrium with the magnetic force exerted on the permanent magnet II 3, the water return flow is reduced at the moment, the pressure in the circulating system is increased, the gas-liquid separation efficiency is improved, and the position of the valve core 7 is restored to the position shown in fig. 2 until.

When the air volume of the circulating system is too large, so that the air content in the return water exceeds a certain value, the valve core 7 can be restored to the initial state (figure 1), the pressure in the circulating system is suddenly increased, and the exhausted air volume can reach more than thousands of times of a rated value, so that the air is forcibly exhausted, and the circulating system is restored to be normal.

The utility model discloses an actuating mechanism is the subassembly that case 7 and two 3 permanent magnet constitutions, should reduce its motion resistance as far as possible. Therefore, the maximum compression amount of the sealing valve 6 should not exceed 10%, and the surface roughness Ra of each contact surface of the valve element 7 and the valve body 5 should not be more than 1.6 μm.
