Description
Technical field
The utility model relates to a kind of high pressure and faces the hydrogen gate valve.
Background technique
The medium scope that high pressure faces the hydrogen gate valve is that hydrogen sulfide etc. has high pressure, corrosive fluid, and high pressure of the present utility model faces the hydrogen gate valve and belongs to a kind of of gate valve.Gate valve is one of valve that blocks fluid flow, and the open-shut device of gate valve is a flashboard.Flashboard has two sealing surfaces, and the most frequently used gate valve is to form wedge shape by two sealing surfaces.The moving direction and the flow direction of flashboard are perpendicular, and gate valve can only be made standard-sized sheet and complete shut-down, can not do to regulate and throttling.When gate valve was in opening state, the passage of fluid was unimpeded fully; When gate valve was in closed state, the passage of fluid was cut off.Sealing is an important parameter of gate valve quality height.As shown in Figure 1, in the prior art, the valve gap 2 that high pressure faces the hydrogen gate valve is to be fixed on the valve body 1 by a valve gap fixed plate 10, and its structure is comparatively complicated; In addition, owing to be subjected to the prior art mesohigh to face the influence of the gear-box 71 and the support 61 between the cover plate 6 of hydrogen gate valve valve, the space of valve gap 2 tops is less, causes maintenance inconvenient; Valve gap 2 is bigger with the matching gap of the transitional cavity 11 of valve body 1 in the prior art, so sealing effect is undesirable.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, more convenient, better high pressure of sealing effect of maintenance and faces the hydrogen gate valve.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of high pressure faces the hydrogen gate valve, form by valve body, valve gap, seat ring, restrictor bar, flashboard, cover plate, gear drive and handwheel, wherein, one end of valve gap is installed in the transitional cavity of valve body, and cover plate is connected with transitional cavity, and seat ring is installed in the valve body, flashboard is installed in the restrictor bar lower end, and the restrictor bar upper end is connected with handwheel by the gear mechanism of gear drive.It is characterized in that: on described cover plate column is installed, the upper end of column is connected with gear-box.
Described column and cover plate be for being threaded, and the quantity of column is 6～8, and evenly distribute ringwise with respect to the center of cover plate.
Described cover plate and valve gap interconnect with screw bolt and nut.
The matching gap of described valve gap and transitional cavity is 0.04～0.06 millimeter.
The internal diameter of the fluid passage of described valve body 〉=150 millimeter.
The invention has the beneficial effects as follows: owing to directly valve gap is fixed on the cover plate with screw bolt and nut, reduced the use of fixed plate, therefore the structure that makes this high pressure face the hydrogen gate valve is simplified; Reduced the matching gap between valve gap and the transitional cavity, the sealing that makes this high pressure face the hydrogen gate valve is improved; On the cover board be provided with column, and it is connected with gear-box, thereby make the operating space of cover plate top increase, thus convenient maintenance.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is explained in detail:
The utility model is that a kind of high pressure faces the hydrogen gate valve, its structure erection drawing as shown in Figure 2, it is made up of valve body 1, valve gap 2, seat ring 3, restrictor bar 4, flashboard 5, cover plate 6, gear drive 7 and handwheel 8, wherein, valve body 1 side is provided with transitional cavity 11, inside is processed with fluid passage 12, the internal diameter of this fluid passage 〉=150 millimeter.The lower end of valve gap 2 is installed in the transitional cavity 11 of valve body 1, and the matching gap of the lower end of valve gap 2 and transitional cavity 11 is 0.04～0.06 millimeter.Cover plate 6 is connected with transitional cavity 11 usefulness screw bolt and nut.Two seat rings 3 are installed in the fluid passage 12 of valve body 1, and they are the wedge shape symmetrical distribution with respect to the center of transitional cavity 11.Flashboard 5 is installed in restrictor bar 4 lower ends, and restrictor bar 4 upper ends are connected with handwheel 8 by the gear mechanism of gear drive 7.By the six roots of sensation column 9 that has been threaded, they evenly distribute ringwise with respect to the center of cover plate 6 on cover plate 6, and the upper end of column 9 is connected with gear-box 71 usefulness screw bolt and nut.Cover plate 6 interconnects with valve gap 2 usefulness screw bolt and nut, its role is to valve gap 2 and valve body 1 are fixed.The course of action that this high pressure faces the hydrogen valve is, by rotating handwheel 8, drives restrictor bars 4 via gear drive 7, and then flashboard 5 is agreed with seat ring 3 and separates, thereby realizes that this high pressure faces closing and opening of hydrogen gate valve.
