Abstract
The utility model relates to a liquid sealing valve, comprising a liquid tank. The liquid tank is provided with an air inlet pipe, an air outlet pipe, a liquid inlet valve and a liquid discharge valve. A plug and a floating box are arranged in the liquid tank. When liquid is discharged to the liquid tank from the liquid inlet valve, the floating box is floated for driving the plug to move up as increased liquid in the liquid tank, and the plug on the floating box is inserted into the air inlet pipe for plugging air. When air is plugged, the height of liquid level is higher than the height of a groove at the lower end part of the elbow of the air inlet pipe The height of liquid level is gradually regulated for changing the circulation area of the air inlet pipe in order to control the flow rate of gas and plugging, and the liquid sealing valve is particularly suitable for controlling and plugging gas with high flow rate and low pressure in a pipe having large pipe diameter.
Description
The utility model relate to a kind of to pipeline gas dam control device, especially can to pipeline gas dam control Liquid sealing valve.
Be the mechanical type valve at present to the pipeline gas control gear commonly used that dams, this valve leak is serious, dispose a liquid seal can behind the door again in order to prevent to leak the mechanical valve of being everlasting, existing liquid seal can water level is wayward, can only shutoff gas and can not control flow rate.
The purpose of this utility model is that a kind of Liquid sealing valve will be provided, and this Liquid sealing valve can dam to gas effectively, prevents to leak, and Liquid sealing valve can not only dam can also control flow rate, and simplified apparatus is saved substantial contribution.
The purpose of this utility model is achieved in that Liquid sealing valve has a flow container, suction tude, steam outlet pipe, feed liquor valve, drainage valve are housed on the flow container, the elbow part of suction tude is put into flow container, the elbow underpart of suction tude has groove equably along circumference, and vertically downward, fluting is in order to change circulation area, control flow rate reposefully gradually, in suction tude elbow both sides setting sleeve is housed, slide bar is moved up and down.A stopper and buoyancy tank in flow container, have been placed, the volume V of buoyancy tank should satisfy the following formula requirement, V＞PS/ ε wherein P is the pressure of suction tude inlet, S is the sectional area of suction tude, ε is the proportion of liquid, a stopper and slide bar on buoyancy tank, have been installed, when liquid (using tap water usually) is put into flow container from the feed liquor valve, increase along with pot liquid, buoyancy tank is floated, buoyancy tank is along slide bar and the fixing position of setting sleeve, the drive stopper moves up, stopper on the buoyancy tank inserts the underpart of suction tude elbow gradually, because the effect of groove, reduce the circulation area of suction tude gradually, thereby realize steadily control and of gas flow to the shutoff of gas, to the complete shutoff of gas the time, the liquid level height of flow container should surpass the position of being slotted in suction tude elbow underpart, fully groove is immersed in the liquid, can make the gas that part is leaked because the stopper shutoff is not tight like this, method by fluid-tight blocks its gas, and suction tude elbow underpart has groove, plays the purpose of part or all of shutoff gas when regulating liquid level height gradually.
The utility model is that existing mechanical valve and two devices of water sealed tank are simplified to a device, suction tude elbow underpart has groove equably along garden week, come the effect of control gaseous flow and shutoff by the circulation area of regulating liquid level Level Change suction tude gradually, be specially adapted to big caliber, big flow, the gas control and the shutoff of low pressure.
Below in conjunction with drawings and Examples the utility model is further specified: be structure sectional view of the present utility model among the figure:
1. flow containers, 2. suction tude, 3. stoppers among the figure, 4. buoyancy tank, 5. drainage valve, 6. feed liquor valve, 7. steam outlet pipe 8. setting sleeves 9. slide bars.
In the drawings, flow container 1 is a closed container, device suction tude 2 on flow container 1, steam outlet pipe 7, feed liquor valve 6, drainage valve 5, the elbow underpart of suction tude 2 has groove equably along garden week, vertically upward, can accurately insert in the suction tude 2, in the elbow both sides of suction tude 2 setting sleeve 8 is housed and cooperate with slide bar 9 for making stopper 3, determine the position that buoyancy tank 4 moves up and down, drainage valve 5 devices have been placed buoyancy tank 4 in the bottom of flow container 1 in the flow container 1, installed stopper 3 and slide bar 9 on buoyancy tank 4, in the time will making gas communication, as long as liquid is bled off from drainage valve 5, buoyancy tank 4 falls automatically, and stopper 3 breaks away from suction tude 2 and gets final product.When wanting shutoff gas, liquid is put into flow container 1 by feed liquor valve 6, the amount of liquid of putting into flow container is according to the requirement of gas flow is decided.In the time will carrying out complete shutoff to gas, the liquid of putting into flow container 1 floats buoyancy tank 4, and stopper 3 moves up, and blocks the pipeline opening of suction tude 2.Stopper 3 can block the gas more than 95%, the gas of small leakage by fluid-tight with the gas shutoff.
Claims (2)
1, a kind of to pipeline gas dam control fluid-tight close, it is characterized in that: flow container (1) is a closed container, go up device suction tude (2) at flow container (1), steam outlet pipe (7), feed liquor valve (6), drainage closes (5), at buoyancy tank (4) gone up device stopper (3) and slide bar (9), for making stopper (3) can insert suction tude (2) exactly, at the elbow both sides of suction tude (2) device setting sleeve (8).
2, Liquid sealing valve according to claim 1 is characterized in that: the elbow underpart in suction tude (2) has groove equably along circumference.
