Abstract
The utility model discloses a low-pressure frog style valve tray, comprising a floating valve and a tower plate. A front valve leg and a rear valve leg are arranged under a valve cover, lower spacing devices are respectively arranged under the front valve leg and the rear valve leg. Valve legs of the low-pressure frog style floating valve are arranged in holes of the tower plate, the two valve legs are movably engaged with each other. The utility model has the advantages of simple structure and easy manufacture. The resistance force of the low-pressure floating valve is small, and thereby the gradient of liquid level is small, the returned mixing phenomenon is reduced, and the heat-transferring and the mass-transferring efficiencies are raised.
Description
Technical field
The utility model relates to a kind of low pressure drop frog type float valve tray.
Background technology
Be provided with column plate and float valve in the destilling tower of petroleum refining industry, column plate generally is made as circle, and float valve is made as rectangle more.Under certain temperature and pressure, carry out gas, liquid separation.But the gradient of liquid level of used tower tray and float valve is bigger, and back-mixing is more serious, and mass-transfer efficiency is lower.
Summary of the invention
The purpose of this utility model provides a kind of low pressure drop frog type float valve tray, has improved the efficient of heat and mass.
The utility model is achieved in that a kind of low pressure drop frog type float valve tray, comprises float valve, column plate, it is characterized in that: be provided with forward and backward valve leg below the valve gap, be respectively equipped with lower retainer below the forward and backward valve leg, the valve leg of low pressure drop frog type float valve is loaded in the column plate hole, between the two for movingly.Be respectively equipped with prominent eaves before and after the valve gap.The valve leg is provided with through hole.Described tower tray is provided with downspout and downspout liquid receiving mouth, and the downspout lower end is provided with anti-back taper.
Advantage of the present utility model:
1. low pressure drop frog type float valve resistance is little, has reduced gradient of liquid level.
2. low pressure drop frog type float valve is formed by connecting by valve gap, valve leg and lower retainer, and is simple in structure, makes easily, and cost is low.
3. column plate is provided with downspout and downspout liquid receiving mouth and many low pressure drop frog type float valves, and the setting of staggering of the downspout of upper and lower adjacent two column plates and downspout liquid receiving mouth has improved mass-transfer efficiency.
Description of drawings
Fig. 1 is a low pressure drop frog type float valve schematic perspective view;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is a low pressure drop frog type float valve tray schematic diagram.
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Low pressure drop frog type float valve tray (Fig. 3) comprises column plate 9, downspout liquid receiving mouth 10, low pressure drop frog type float valve 11, downspout 12 and anti-back taper 13.Downspout liquid receiving mouth and downspout are connected as a single entity and are loaded in the column plate, stagger mutually in the downspout position on upper and lower adjacent two column plates.The downspout lower end back taper of setting up defences.Column plate is provided with several column plate holes, and a low pressure drop frog type float valve respectively is housed in the column plate hole, and low pressure drop frog type float valve valve leg and column plate hole are for movingly.Low pressure drop frog type float valve comprise valve gap 4, preceding valve leg 8, back valve leg 2, lower retainer 3,7,, (Fig. 1, Fig. 2), the two ends of valve gap are respectively equipped with prominent eaves 1,5, and the lower end of forward and backward valve leg 8,2 is respectively equipped with lower retainer 7,3, and forward and backward valve leg is provided with through hole 6.The extreme lower position of valve gap is by prominent eaves 1,5 controls, and the open maximum height of valve gap is limited by lower retainer 3,7.The length-width ratio of the valve gap of present embodiment is L: B=2: 1, and the deployed height H=B of valve gap.
Claims (4)
1. a low pressure drop frog type float valve tray comprises float valve, and column plate is characterized in that: be provided with forward and backward valve leg below the valve gap, be respectively equipped with lower retainer below the forward and backward valve leg, the valve leg of low pressure drop frog type float valve is loaded in the column plate hole, between the two for movingly.
2. low step-down frog type float valve tray as claimed in claim 1 is characterized in that: be respectively equipped with prominent eaves before and after the valve gap.
