Description
Technical field
The present invention relates to a kind of erecting device, in particulars relate to one kind and is used for the online erecting device of upper-mounting type ball valve valve seat.
Background technology
As upper-mounting type ball valve is widely used in the new energy device such as LNG, long-distance transport pipes, due to its lumen valve chamber space
The reason such as small, compact-sized, existing mounting means need to increase technique screw hole on valve body to be realized, but because screw hole itself is tied
The influence of structure, online installation effectiveness lowly even causes valve leakage out of steam system situation to frequently occur, how short in maintenance cycle, does not influence
On the premise of valve overall performance, realize that its valve seat internals is mounted for the important difficulty that major valve manufacturer faces online
Topic.
The content of the invention
The purpose of the application is the defects of being directed to the prior art, there is provided a kind of online erecting device of upper-mounting type ball valve valve seat,
The device can be realized to valve seat internals steady erecting device online, so as to realize upper-mounting type ball valve on the premise of maintenance cycle is short
Online Fast Installation and then satisfaction maintenance etc. require.
The technical solution of the application is：A kind of online erecting device of upper-mounting type ball valve valve seat, including：Bearing, screw rod, branch
Stent, branch are set above frame, nut, guide rod, guide sleeve, pressing plate, holding screw, thread bush and plane bearing, wherein bearing
Frame is hollow ring-shaped work pieces, sets guide rod and screw rod, guide rod and screw rod to be arranged in parallel in the bracket, and guide rod and
Screw rod is set along the radial direction of stent hollow space, and wherein guide rod is fixed on stent by nut, is contacted in screw rod with stent
Plane bearing is set between face, the part body of screw rod stretches out stent, and the part for stretching out the screw rod of stent is outer-hexagonal structure,
Set in stent and run through guide rod and screw flight set, holding screw is set on thread bush, set and be oriented on thread bush top
On the guide bar, pressing plate is arranged on above guide rod the socket of set and pressing plate, wherein guide sleeve.
A kind of online erecting device of upper-mounting type ball valve valve seat as described above, wherein, pass through soket head cap screw above bearing
It is fixedly connected with stent.
The remarkable result of the application is：
1. clever structure, using quick
Since using combination unit structure, clever structure, overall weight is lighter, and personnel easy to repair carry.Pedestal at the same time
Connection mode is consistent with valve body middle chamber, Fast Installation when being used so as to fulfill the present apparatus.
2. service using life is permanent
Screw rod and baffle connecting portion use thread bush transition, cause after avoiding long-time use because of thread abrasion entirely
Device is scrapped, and as abrasion condition occurs in screw thread, device can be reused after only needing to change thread bush.Connect in baffle and guide rod
Socket part position uses guide sleeve transition, and avoiding baffle, casey destroys guide rod situation generation during the work time, so as to extend dress
Put service life.
3. reduce maintenance personal's working strength in installation process
Screw rod can produce axial power in rotation process and apply on screw rod and stent contact surface, so as to produce larger
Frictional force, for this reason, increasing plane bearing between screw rod end face and stent, avoids significantly frictional force generation, so as to reduce maintenance
Personnel pull screw rod rotation work intensity.

Embodiment
The application is described further below in conjunction with the accompanying drawings：
1 bottom connection mode of pedestal and valve body middle chamber connection mode as shown in Figure 1, Figure 2, Figure 3 shows is consistent, and top is adopted
With 11 both sides connecting bracket 3 of soket head cap screw, while by guide rod 5 and screw rod 2, (it is outer-hexagonal knot that screw rod 2, which protrudes 3 part of stent,
Structure, purpose spanner easy to use are pulled screw rod 2 and are rotated), baffle 7 be installed on the inner side of stent 3, between 3 contact surface of screw rod 5 and stent
Increase plane bearing 10, to ensure structural stability, fastened in guide rod both ends of the surface using nut 4, so as to ensure this dress
It is set to as a constitutionally stable rigid body, while also realizes and easily rotated when spanner pulls screw rod 2 in the inner side of stent 3.
Increase by 9 transition of thread bush for a long time between baffle 7 and screw rod 2 for guarantee present apparatus service life and use clamp screw
The fastening of nail 8, prevents 9 transfer of thread bush, while increases guide sleeve 6 in baffle 7 and between being oriented to dry 5, avoids baffle from being transported in level
The situation for occurring casey during dynamic occurs.
The use process of the application device approximately as：As shown in Figure 4, Figure 5, first valve seat 13 is pre-installed to upper-mounting type ball valve
After 12 endoporus of valve body, then after present apparatus unit combined isolator 3 is connected with upper-mounting type ball valve valve body 12, using positioning pin 16 and upper
Dress formula ball valve body 12 is positioned, and the fastening present apparatus and upper-mounting type ball valve valve body 12 is carried out using stud and nut, so as to protect
It is vertical with runner center to demonstrate,prove pressing plate 7, after installing, screw rod 2 is pulled counterclockwise with spanner 15, you can realize that pressing plate 7 is surely horizontal
It is mobile in terms of valve seat 13, so as to precisely smoothly promote valve seat 13 to install to precalculated position, then pulled clockwise with spanner 15
Dynamic screw rod 2, you can realize pressing plate 7 away from valve seat 13 to safe space, dismounting stud with after nut, you can take out the present apparatus, soon
Valve seat work is once installed in the completion of speed online.
