Abstract
The utility model discloses a be applied to gland of gate valve, including gland body and gland head, the gland body is equipped with the step hole that supplies the valve rod to pass in vertical direction, the aperture of this step hole lower part is less than the aperture on upper portion, placed the sealing washer in proper order and fixed a position the packing ring by supreme down on the step face in step hole, this sealing washer and the internal diameter of location packing ring and the external diameter looks adaptation of valve rod, the gland head is equipped with with step hole intercommunication in vertical direction and supplies the through -hole that the valve rod passed, threaded connection is passed through with the upper portion in step hole in the lower part of gland head. Having placed sealing washer and location packing ring on the step face in step hole, should having fixed a position the packing ring and make the valve rod can not take place the skew in vertical orientation, screwed when being connected when the lower part of gland head and the upper portion in step hole, the gland head will fix a position the packing ring and the sealing washer compresses tightly, this moment sealing washer and fix a position the inside wall of packing ring and the lateral wall in close contact with of valve rod to realize the sealed and location between valve rod and the step hole.
Description
Technical field
The utility model relates to valve field, refers to a kind of gland being applied to gate valve specifically.
Background technique
In various types of valve, gate valve is most widely used one, and it mainly plays the effect cutting off medium on pipeline, can be used for the environment of High Temperature High Pressure, various liquid mediums.The gland that existing gate valve comprises valve body and is connected with valve body, gland is provided with the through hole passed for valve rod, usually, needs sealing, prevent the leakage of liquid between through hole and valve rod.At present, the sealing between through hole and valve rod offers seal groove by the outer side wall at valve rod, is placed with the seal ring suitable with it, reaches sealing effect with this in sealing groove.But comparatively difficult when above-mentioned sealing means makes seal ring change, gate valve is inconvenient when keeping in repair.
Model utility content
The utility model provides a kind of gland applying gate valve, and its main purpose is that the seal ring overcoming existing gate valve gland is comparatively difficult when changing, the problem of gate valve inconvenience when keeping in repair.
In order to solve above-mentioned technical problem, the utility model adopts following technological scheme:
A kind of gland being applied to gate valve, comprise gland body and crownewr head, described gland body in the vertical direction is provided with the step hole passed for valve rod, the aperture of this step hole bottom is less than the aperture on top, the step surface of described step hole is placed with seal ring and space washer from the bottom to top successively, the internal diameter of sealing circle and space washer and the external diameter of valve rod suitable, described crownewr head in the vertical direction is provided with and is communicated with and the through hole passed for valve rod with step hole, and the bottom of described crownewr head and the top of step hole are threaded connection.
Further, described seal ring and space washer are provided with many groups.
Further, described seal ring and space washer are provided with two groups.
Further, described space washer is tetrafluoro packing ring.
Further, described gland body is provided with two symmetrically arranged attachment holes.
From above-mentioned to description of the present utility model, compared to the prior art, the utility model tool has the following advantages: the utility model is reasonable in design, structure is simple, the step surface of described step hole is placed with seal ring and space washer, this space washer makes valve rod in the vertical direction to offset, while the bottom of crownewr head and the top of step hole screw and are connected, space washer and seal ring compress by crownewr head, the now madial wall of seal ring and space washer and the outer side wall close contact of valve rod, thus realize valve rod and and step hole between sealing and location.When seal ring changed by needs, crownewr head is rotated and unclamps, gland body is separated with valve rod, seal ring can be taken out in step hole, change fast.Adopt the utility model not only without the need to carrying out the processing of seal groove to valve rod, and seal ring is changed easily, gate valve is convenient when keeping in repair.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic that the utility model is connected with valve rod.
Fig. 2 is cross-sectional schematic of the present utility model.
Fig. 3 is the cross-sectional schematic of the utility model gland body.
Embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3.Be applied to a gland for gate valve, comprise gland body 1 and crownewr head 2, described gland body 1 in the vertical direction is provided with the step hole 4 passed for valve rod 3, and the aperture of this step hole 4 bottom is less than the aperture on top.The step surface 41 of described step hole 4 is placed with seal ring 5 and space washer 6 from the bottom to top successively, the internal diameter of sealing circle 5 and space washer 6 and the external diameter of valve rod 3 suitable, described crownewr head 2 in the vertical direction is provided with and is communicated with and the through hole 7 passed for valve rod 3 with step hole 4, and the bottom of described crownewr head 2 and the top of step hole 4 are threaded connection.
See figures.1.and.2.Described seal ring 5 and space washer 6 are provided with two groups, and these two groups superpose from the bottom to top, adopt many group seal rings 5 and space washer 6 can increase sealing effect further and keep the perpendicularity of valve rod 3.Described space washer 6 is tetrafluoro packing ring, and tetrafluoro packing ring has the advantages such as corrosion resistance is strong, aging quality resistance is good.Described gland body 1 is provided with two symmetrically arranged attachment holes 11, and this two attachment hole 11 coordinates with bolt locks this gland with on valve body.
With reference to Fig. 1 and Fig. 3.Use principle of the present utility model is as follows: the step surface 41 of described step hole 4 is placed with seal ring 5 and space washer 6, and this space washer 6 makes valve rod 3 in the vertical direction to offset.While bottom and the top of step hole 4 of crownewr head 2 screw and are connected, space washer 6 and seal ring 5 compress by crownewr head 2, the now madial wall of seal ring 5 and space washer 6 and the outer side wall close contact of valve rod 3, thus realize valve rod 3 and and step hole 4 between sealing and location.When seal ring 5 changed by needs, crownewr head 2 is rotated and unclamps, gland body 1 is separated with valve rod 3, seal ring can be taken out in step hole, change fast.
Above are only embodiment of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
