Description
Technical field
The utility model is a kind of seal spool device of pipeline dimension repairing exclusive clamps plate valve.Relate to the pipe-line system technical field.
Background technique
Pipeline dimension repairing exclusive clamps plate valve is a kind of special valve that is used for pipeline dimension repairing operation, is extensive use of when carrying out press and open holes, shutoff operation on long distance pipeline and industrial pipeline.
Because this sandwich valve often is with to press and is used in the various media environments, wherein the sealing of spool and last lower valve plate relies on the seal arrangement between spool and the last lower valve plate fully.Because it is frequent at work progress middle clamp plate threshold switch number of times, and pressure, temperature and the medium physicochemical properties of pipeline internal medium also have nothing in common with each other when using at every turn, in pipeline dimension repairing process, guarantee that again sandwich valve does not have leakage, so when daily plant maintenance, just need often change to the seal ring of sandwich valve.But the seal arrangement of original sandwich valve design is on spool, changing sealing must disintegrate to sandwich valve, and because restrictive conditions such as sandwich valve assembly precision requirements, cause change the sealing time long, difficulty is big, technical merit to the attendant of sandwich valve is had relatively high expectations, and also can't satisfy the job site and seal the replacing requirement temporarily.
The model utility content
The purpose of this utility model is a kind of convenient replacing that seals of design, shortens the time of replacing sealing, satisfies the seal spool device that the pipeline dimension of temporarily changing the Sealing demand in the job site is rushed to repair the exclusive clamps plate valve.
The utility model has carried out new design at the deficiency of existing sandwich valve seal arrangement, its structure such as Fig. 1-and shown in Figure 4.Existing sandwich valve comprises valve plate 1, middle valve plate 2, spool 3 and lower valve plate 4, be middle valve plate 2 middle cover upper valve cores 3 after, by last valve plate 1 and lower valve plate 4 from upper and lower two sides with valve plate 2 and spool 3 clamp fixing; The utility model is on this basis, increases sealing inner clip plate 5, sealing outer plate 6, pressing plate sunk screw 7 and O type circle 8; The hole of being passed on sealing inner clip plate 5, the sealing outer plate 6 by pressing plate sunk screw 7 will seal inner clip plate 5 and seal the inboard that outer plate 6 is fixed on valve plate 1, sealing inner clip plate 5, sealing outer plate 6 are clipped between valve plate 1 and the spool 3, in the middle of sealing inner clip plate 5 and sealing outer plate 6, O type circle 8 are installed.
Formed the seal groove of dovetail groove shape after described sealing inner clip plate 5 and sealing outer plate 6 are assembled on valve plate 1 and the lower valve plate 4, O type circle 8 is installed in the dovetail groove.
Wherein:
The shape of sealing inner clip plate 5 as shown in Figure 5 and Figure 6, it be circular, the following outer of annulus is stretched out one and is gone up straight angle under the circular arc, and is equipped with a plurality of holes on encircling;
The shape of sealing outer plate 6 as shown in Figure 7 and Figure 8, it be circular, the annular distance lower edge is inwardly stretched out one and is gone up straight angle under the circular arc, and is equipped with a plurality of holes on encircling.
Sealing inner clip plate 5, sealing outer plate 6 are nested and are fixed on the interior rear flank of valve plate 1, and sealing inner clip plate 5 outwardly directed angles just in time form circular-arcly with sealing angle that outer plate 6 inwardly stretches out, match with the profile of O type circle 8.
The utility model after regaining spool 3, by removing sealing inner clip plate 5, takes off O type circle 8 in use, can change.
The utility model is by adjusting the position of seal arrangement, and sealing configuration improved, reduced the difficulty of plant maintenance, made things convenient for the replacing of sealing, shorten the time requirement of changing sealing greatly, also satisfied the demand that Sealing is changed in the job site temporarily.

Embodiment:
Embodiment: the utility model will be further described in conjunction with example, but example is not to restriction of the present utility model.
This example is the seal spool device that is used for Φ 1016mm sandwich valve, its structure as shown in Figure 1-Figure 3, be to comprise on the basis of valve plate 1, middle valve plate 2, spool 3 and lower valve plate 4, increase sealing inner clip plate 5, sealing outer plate 6, pressing plate sunk screw 7 and O type circle 8 at original sandwich valve; Seal inner clip plate 5, seal the inboard that outer plate 6 is fixed on valve plate 1 by 7 of pressing plate sunk screws, sealing inner clip plate 5, sealing outer plate 6 are clipped between valve plate 1 and the spool 3, in the middle of sealing inner clip plate 5 and sealing outer plate 6, O type circles 8 are installed.
Formed the seal groove of dovetail groove shape after described sealing inner clip plate 5 and sealing outer plate 6 are assembled on valve plate 1 and the lower valve plate 4, O type circle 8 is installed in the dovetail groove.
Wherein:
The shape of sealing inner clip plate 5 as shown in Figure 5 and Figure 6, it be circular, the following outer of annulus is stretched out one and is gone up straight angle under the circular arc, and is equipped with a plurality of holes on encircling; External diameter 1062mm, internal diameter 1015mm, thick 7.5mm;
The shape of sealing outer plate 6 as shown in Figure 7 and Figure 8, it be circular, the annular distance lower edge is inwardly stretched out one and is gone up straight angle under the circular arc, and is equipped with a plurality of holes on encircling; The external diameter 1109mm of sealing outer plate 6, internal diameter 1062mm, thick 7.5mm;
Pressing plate sunk screw 7 is the sunk screw of M5X16mm.
When valve was in closed condition, the sealing of valve was sealed by the sealing device.When valve was in full open mode, when spool 3 was regained fully, spool 3 edges had passed through sealing inner clip plate 5 and O type circle 8, and can change O type circle 8 this moment by removing sealing inner clip plate 5.
This example is by field experiment, and this seal arrangement can guarantee that valve bears 10MPa pressure.The time that the skilled worker changes seal ring also can be controlled at about 15-20 minute, greatly reduces labor intensity, owing to do not need sandwich valve is disintegrated, does not have special site requirements, has also satisfied the requirement of field construction field maintenance.
