Abstract
The utility model relates to an opening type stuffing structure of a flat gate valve. The opening type stuffing structure of the flat gate valve comprises a valve deck, a valve rod and a support. A stuffing box is fixed to the valve deck through the support. The valve rod is installed in the stuffing box. Flexible graphite is arranged between the stuffing box and the valve rod and pressed into the stuffing box through a stuffing box gland. A bolt connected with the support is further arranged on the stuffing box gland. A sealing base is arranged on the valve deck. According to the opening type stuffing structure of the flat gate valve, the flexible graphite is arranged between the stuffing box and the valve rod, so that the sealing performance between the valve rod and the stuffing box is guaranteed; when a medium is leaked from the portion of the stuffing box gland, the stuffing box gland can be pressed through the method that the bolt on the stuffing box gland is screwed tightly, and the stuffing sealing purpose is achieved; when the valve rod is moved and abrasion leakage of stuffing is generated, the operation is repeated so that the valve rod can be sealed.
Description
Technical field
The utility model relates to a kind of plate valve open type filling-material structure, belongs to plate valve technical field.
Background technique
Plate valve is widely used in oil, chemical industry, long-distance transport pipes, oil jetty and irrigated area, and plate valve has good seal performance, long service life.The advantages such as unlatching moment of torsion is little, and structure length is short, still, there is sometimes dielectric leakage in valve stem seal place in plate valve in long-term use, and this leakage is processed very difficult now, affect valve and normally move.
Model utility content
The utility model object is the plate valve open type filling-material structure that a kind of good sealing effect is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of plate valve open type filling-material structure, comprise valve gap, valve rod, support, and on described valve gap, by support, be fixed with stuffing box; Described valve rod is arranged in stuffing box; Between described stuffing box and valve rod, be provided with Expanded graphite; Described Expanded graphite is pressed in stuffing box by Gland; On described Gland, be also provided with the bolt being connected with support; Described valve gap is provided with sealing seat.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of plate valve open type filling-material structure of the utility model scheme, by Expanded graphite being set between stuffing box and valve rod, guarantee the sealing between valve rod and stuffing box, when having medium to leak from Gland, can compress Gland by the bolt of tightening on Gland, reach packing seal, work as stem movement, when filler has wear and leakage, repeat aforesaid operations and can realize valve stem seal.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the schematic diagram of a kind of plate valve open type filling-material structure of the present utility model;
Wherein: 1, valve gap; 2, valve rod; 3, support; 4, stuffing box; 5, Expanded graphite; 6, Gland; 7, bolt; 8, sealing seat.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is a kind of plate valve open type filling-material structure described in the utility model, comprises valve gap 1, valve rod 2, support 3, on described valve gap 1, by support 3, is fixed with stuffing box 4; Described valve rod 2 is arranged in stuffing box 4; Between described stuffing box 4 and valve rod 2, be provided with Expanded graphite 5, guarantee the sealing between valve rod 2 and stuffing box 4; Described Expanded graphite 5 is pressed in stuffing box 4 by Gland 6; On described Gland 6, be also provided with the bolt 7 being connected with support 3, when having medium to leak from Gland 6, can compress Gland 6 by the bolt 7 of tightening on Gland 6, reach packing seal; When valve rod 2 motions, when filler has wear and leakage, repeat aforesaid operations and can realize valve rod 2 sealings; Described valve gap 1 is provided with sealing seat 8, there is sealing function, when valve is in operation discovery packing leaking, the flashboard of valve is reached after fully open position, with manually continuing out valve, until valve rod 2 contacts and can realize the sealing of valve rod 2 stuffing boxes 4 with the sealing seat 8 of valve gap 1.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
