Abstract
The utility model relates to a kind of packing of gate valve structure, comprises valve gap, valve rod, support; Described support and valve gap are bolted to connection; Described valve gap is installed with stuffing box by support; Described valve rod is arranged in stuffing box; Expanded graphite is provided with between described stuffing box and valve rod; Described Expanded graphite is pressed in stuffing box by Gland; Described Gland is provided with the screw rod be connected with support; Also spring is provided with between described stuffing box and Gland; Described spring one end holds out against bottom Gland, and the other end holds out against on the seal ring of stuffing box upper end; Described valve rod stretches out Gland end and is also provided with clamp ring; The utility model scheme can make directly not contact between Gland with stuffing box, avoids damaging, and also can well play gland sealed effect, work as stem movement, when filler has a wear and leakage, repeats aforesaid operations and can realize valve stem seal.
Description
Technical field
The utility model relates to a kind of packing of gate valve structure, belongs to plate valve technical field.
Background technique
Plate valve widely uses 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, but there is dielectric leakage sometimes in plate valve valve stem seal place in Long-Time Service, and this leakage is very difficult in process now, affects valve and normally runs.
Model utility content
The utility model object is the packing of gate valve structure providing a kind of good sealing effect 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 packing of gate valve structure, comprises valve gap, valve rod, support; Described support and valve gap are bolted to connection; Described valve gap is installed with stuffing box by support; Described valve rod is arranged in stuffing box; Expanded graphite is provided with between described stuffing box and valve rod; Described Expanded graphite is pressed in stuffing box by Gland; Described Gland is provided with the screw rod be connected with support; Also spring is provided with between described stuffing box and Gland; Described spring one end holds out against bottom Gland, and the other end holds out against on the seal ring of stuffing box upper end; Described valve rod stretches out Gland end and is also provided with clamp ring.
Preferably, also sealing seat is provided with valve rod joint bottom described valve gap.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of packing of gate valve structure of the utility model scheme, by arranging Expanded graphite between stuffing box and valve rod, ensure the sealing between valve rod and stuffing box, also spring is provided with between stuffing box and Gland, spring one end holds out against bottom Gland, the other end holds out against on the seal ring of stuffing box upper end, like this when there being medium to leak from Gland, Gland can be compressed by the screw rod tightened on Gland, spring plays a buffer function, can make directly not contact between Gland with stuffing box, avoid damaging, also gland sealed effect can well be played, work as stem movement, when filler has a 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 packing of gate valve structure of the present utility model;
Wherein: 1, valve gap; 2, valve rod; 3, support; 4, bolt; 5, stuffing box; 6, Expanded graphite; 7, Gland; 8, screw rod; 9, spring; 10, seal ring; 11, clamp ring; 12, 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 packing of gate valve structure described in the utility model, comprises valve gap 1, valve rod 2, support 3; Described support 3 is fixedly connected with by bolt 4 with valve gap 1; Described valve gap 1 is installed with stuffing box 5 by support 3; Described valve rod 2 is arranged in stuffing box 5; Expanded graphite 6 is provided with between described stuffing box 5 and valve rod 2; Described Expanded graphite 6 is pressed in stuffing box 5 by Gland 7; Described Gland 7 is provided with the screw rod 8 be connected with support 3; Spring 9 is also provided with between described stuffing box 5 and Gland 7; Described spring 9 one end holds out against bottom Gland 7, and the other end holds out against on the seal ring 10 of stuffing box 5 upper end; Described valve rod 2 stretches out Gland 7 end and is also provided with clamp ring 11; Sealing seat 12 is also provided with valve rod 2 joint bottom described valve gap 1.
A kind of packing of gate valve structure of the utility model scheme, by arranging Expanded graphite 6 between stuffing box 5 and valve rod 2, ensure the sealing between valve rod 2 and stuffing box 5, spring 9 is also provided with between stuffing box 5 and Gland 7, spring 9 one end holds out against bottom Gland 7, the other end holds out against on the seal ring 10 of stuffing box 5 upper end, like this when there being medium to leak from Gland 7, Gland 7 can be compressed by the screw rod 8 tightened on Gland 7, spring 9 plays a buffer function, can make directly not contact between Gland 7 with stuffing box 5, avoid damaging, also gland sealed effect can well be played, when valve rod 2 moves, when filler has a wear and leakage, repeat aforesaid operations and can realize valve stem seal.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
