Abstract
The utility model relates to a fast installed float valve for a tower device. The utility model is composed of a valve surface and a valve seat, wherein, the valve seat comprises a supporting leg and elastic inverse hooks, the supporting leg forms a sheet shape, and the elastic inverse hooks are directly punched on the supporting leg; the elastic inverse hooks are positioned on the center part of the supporting leg, on both sides of the supporting leg, or on one side of the supporting leg. When the float valve is installed, when the elastic inverse hooks pass through a valve hole, the elastic inverse hooks which are stressed are shrunk; after the elastic inverse hooks pass through the valve hole, the elastic inverse hooks are opened again because of elasticity, and the float valve is clamped in the valve hole. The utility model has the advantages of fast installation, no easy disengagement, reliable operation, and guaranteed production quality.
Description
The utility model relates to a kind of tower fast-assembling float valve, and it is the critical piece on widely used destilling tower, absorption tower in oil refining, the chemical industry, belongs to the gas-liquid contact mass transfer technical field in oil refining, the chemical industry equipment.
Used float valve in the domestic and international widely used valve plate generally all is made up of valve face and valve seat, and its structure as depicted in figs. 1 and 2.Float valve be shaped as rectangle, circle or other shape, the valve seat under the valve face 1 comprises leg 2 and fin 3.During installation, earlier leg is positioned in the valve opening, again fin 3 is reversed 90 °.Owing in the tower, thousands of float valves are housed, so the installation of float valve is time-consuming, influences project progress.In addition, if in installing carelessness is arranged slightly, fin reverses not in place, will cause float valve loosening, rotates even comes off, and not only influences the normal running of column plate, and influences product quality.
The purpose of this utility model is a kind of tower of design fast-assembling float valve, improves the structure of float valve in the prior art, on the leg of float valve resilient barb is set, so that the float valve installation is fast, and difficult drop-off.
The tower fast-assembling float valve of the utility model design is made up of valve face and valve seat.Wherein valve seat comprises leg and resilient barb, and leg is a sheet, and resilient barb directly is stamped to form on leg.Resilient barb is in centre, both sides or a side of leg.When elastic hook was in the both sides of leg, the leg middle part had bar hole.
The tower fast-assembling float valve of the utility model design, the stressed contraction the time of resilient barb on the valve seat by valve opening, by opening owing to elasticity behind the valve opening, thereby float valve is stuck in the valve opening, this has just accelerated the installation rate of float valve widely, as long as valve seat is aimed at valve opening firmly to be pressed and can install, and the float valve difficult drop-off, the column plate normal running guaranteed.
Description of drawings:
Fig. 1 and Fig. 2 are the structural representations of float valve in the prior art.
Fig. 3 is the float valve structural representation of the utility model design.
Fig. 4 is two kinds of versions in addition of the present utility model.
Below in conjunction with accompanying drawing, describe content of the present utility model in detail.Fig. 1 and Fig. 2 are widely used rectangular valve and circular float valves in the prior art, among the figure, and the 1st, valve face, the 2nd, leg, the 3rd, fin.Fig. 3 is the fast-assembling float valve of the utility model design.On the base of valve face 1, leg 4 is housed, the both sides of leg 4 stamp out two resilient barb 5.During float valve is installed, barb 5 is subjected to force compresses by ports valve the time, by opening again owing to elasticity again behind the valve opening, thereby whole float valve is stuck in the valve opening, the another kind of version of valve seat among among Fig. 36 and 7, barb 6 is in the both sides of leg 7, has slot in the centre of leg 7, and this hole effect is to lead.Figure 4 shows that two kinds of versions in addition of valve seat, among Fig. 4, resilient barb 9 is in the centre of leg 8, and an end and the leg of barb link.Resilient barb 11 is in a side of leg 10, can be in the right side, as shown in the figure, also can be in the left side.
Claims (2)
1, a kind of tower fast-assembling float valve is made up of valve face and valve seat, it is characterized in that valve seat wherein comprises leg and resilient barb, and leg is a sheet, and resilient barb is stamped to form on leg, and resilient barb is in centre, both sides or a side of leg.
2, fast-assembling float valve as claimed in claim 1 is characterized in that when elastic hook is in the both sides of leg, and the leg middle part has bar hole.
