Description
Technical field
The utility model belongs to chemical technology field, specifically, relates to a kind of floating top cover connection for bbreather pipe.
Background technology
The floating roof of floating roof tank is a floating top cover swimming on storage liquid surface, floating top cover fluctuates along with the input and output of liquid storage, an annular space is had between floating roof and tank skin, this annular space has a sealing arrangement, make pot liquid when top cover fluctuates and atmospheric isolation, thus greatly reduce the boil-off loss of liquid storage in storage process.When adopting floater to store oil product, comparable fixed tank reduces oil product loss about 80%.
But when floating top cover runs to tank body lower part, the space that floating top cover and tank body are formed easily forms superpressure or vacuum, thus damages floating top cover.
Utility model content
The utility model overcomes shortcoming of the prior art, provides a kind of floating top cover connection for bbreather pipe, and the space preventing floating top cover and tank body from being formed easily forms superpressure or vacuum, damage floating top cover, and prevent rainwater from entering in tank body, make floating top cover safe operation, ensure to produce.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of floating top cover connection for bbreather pipe, comprise valve body, described valve body is arranged at described floating top cover, described valve body upper end is provided with valve gap, described valve gap is round platform or terrace with edge, the top surface area of described valve gap is greater than its base area, the base area of described valve gap is greater than the upper surface area of described valve body, the edge of described valve gap is to downward-extension weather shield, described valve gap is fixed with vertical valve rod, described valve rod extends downwardly through described floating top cover place plane, the length of described valve rod below described floating top cover is less than the length of described weather shield, described valve body is equipped with pulley in described valve rod both sides.
Further, described valve body is provided with baffle plate below described pulley.
Further, the junction of described valve body and described floating top cover is socketed with stiffening ring.
Further, the lower surface of described valve gap is provided with seal ring.
Compared with prior art, the beneficial effects of the utility model are:
A kind of floating top cover connection for bbreather pipe described in the utility model, effectively prevents from forming superpressure or vacuum between tank body and floating top cover, and damage floating top cover, and effectively prevent valve gap top ponding, when valve gap is opened, rainwater also can not enter in tank body from its side.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, is used from explanation the utility model with embodiment one of the present utility model, does not form restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of a kind of floating top cover connection for bbreather pipe described in the utility model.
In figure, 1---valve body; 2---floating top cover;
3---valve gap; 4---seal ring;
5---weather shield; 6---valve rod;
7---pulley; 8---baffle plate;
9---stiffening ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of floating top cover connection for bbreather pipe described in the utility model, comprise valve body 1, valve body 1 is arranged at floating top cover 2, lower end and the floating top cover 2 of valve body 1 are welded, valve body 1 upper end is provided with valve gap 3, the lower surface of valve gap 3 is provided with seal ring 4, sealing is better, valve gap 3 is round platform or terrace with edge, the top surface area of valve gap 3 is greater than its base area, the base area of valve gap 3 is greater than the upper surface area of valve body 1, this design prevents at valve gap 3 upper surface ponding, the edge of valve gap 3 is to downward-extension weather shield 5, valve gap 3 is fixed with vertical valve rod 6, valve rod 6 extends downwardly through floating top cover 2 place plane, the length of valve rod 6 below floating top cover 2 is less than the length of weather shield 5, when valve rod 6 is by valve gap 3 jack-up, weather shield 5 covers valve gap 3 both sides, prevent rainwater from entering from the side.
Simultaneously, valve body 1 is equipped with pulley 7 in valve rod 6 both sides, guide valve rod 6 and valve gap 3 vertical motion, when preventing valve gap 3 by valve rod 6 jack-up, run-off the straight, rainwater or foreign material enter in tank body, and valve body 1 is provided with baffle plate 8 below pulley 7, prevent the oil product in tank body from splashing on pulley 7, affect pulley 7 and work.
The junction of valve body 1 and floating top cover 2 is socketed with stiffening ring 9, prevents the position of weld ponding of valve body 1 and floating top cover 2, causes corrosion.
Working process of the present utility model is:
When floating top cover 2 rises, valve gap 3 falls automatically, seals with valve body 1 seal ring 4, when floating top cover 2 runs to tank base, valve rod 6 first contacts with tank base, is automatically backed down by valve gap 3, therefore effectively avoids producing superpressure or vacuum between floating top cover 2 and tank body.
Last it is noted that these are only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; but it is all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
