In the installation process of valve plate, since valve plate can not be smoothly mounted among two valve seats by clearance issues, such as
Shown in Fig. 1 to Fig. 4, set in the valve chamber 11 of valve body 1 there are two valve seat, each valve seat include preceding valve seat 4 and be arranged at it is described before
Rear valve base 5 on valve seat 4, rear valve base 5 are equipped with rectangular seal 6, and rectangular seal 6 is arranged at the rectangular seal of rear valve base 5
In ring recess, due to rectangular seal 6 width be more than rectangular seal slot depth, so as to rectangular seal 6 can generate it is certain
Interference volume a, as shown in Figure 2 so that the valve seat in valve chamber 11 is reduced in valve chamber 11 to off-centring between two preceding valve seats 4
Distance so that before what valve plate 2 can not be successfully be installed among valve seat 4；It is and oblique equipped with 15 degree of guiding in the end of valve plate 2
Angle, as shown in figure 4, when the lower end of valve plate 2 once be inserted into two preceding valve seats 2 it is intermediate when, at this time with the square at 5 back side of rear valve base
Shape sealing ring 6 is used as fulcrum, and the upper end of valve seat can be caused to deviate outward so that and the space between two valve seats is wide at the top and narrow at the bottom,
As shown in figure 3, this is very unfavorable to the installation of valve plate 2, therefore, it is necessary to design a kind of brand-new valve plate centralizing tool convenient for valve
The installation of plate 2.
Therefore, it is necessary to a kind of new technical solution is provided to overcome drawbacks described above.
Utility model content
The purpose of this utility model is to provide a kind of Novel valve seat centralizing tools that can effectively solve above-mentioned technical problem.
To reach the purpose of the utility model, adopt the following technical scheme that：
A kind of Novel valve seat centralizing tool, the Novel valve seat centralizing tool include screw rod and are arranged on the screw rod
Drag hook, the screw rod include positioned at its one end first end and the second end positioned at its other end, the first end and
The external screw thread direction of rotation of the second end is on the contrary, the drag hook sets there are two and is respectively arranged at first end and the second end
On, the drag hook is threadedly coupled respectively with first end and the second end, and the drag hook is equipped with support portion, and the support portion is set
In two drag hooks one end close to each other.
The first end and the second end are integrally formed.
The support portion is integrally formed with the drag hook.
Compared with prior art, the utility model has the advantages that：The utility model Novel valve seat centralizing tool
Smoothly valve plate can be installed among valve seat so that two valve seats keep relatively parallel, will not be right convenient for the installation of valve plate
Valve seat and valve plate cause to scratch, convenient for ensureing sealing effect.Can be tilted simultaneously to avoid valve seat causes rectangular seal to come off, squeeze
Break, ensure the sealing effect of rectangular seal.And at the same time ensureing valve plate once mounting in place, installation effectiveness is high, and ties up
Shield and maintenance are simple, safe and reliable.

Specific embodiment
Clearly complete explanation is made to the utility model Novel valve seat centralizing tool below in conjunction with attached drawing 1-6.
As shown in figures 1 to 6, the utility model Novel valve seat centralizing tool is mainly used for the valve seat installation of valve body 1, such as Fig. 1 and
Shown in Fig. 2, valve body 1 therein includes valve chamber 11, the through hole 12 at left and right sides of valve chamber 11, the valve plate being arranged on valve body 1
2nd, valve seat, the support plate 3 being arranged on valve seat and the rectangular seal being arranged on valve seat of the left and right sides in valve chamber 11 are contained in
Circle 6, the valve seat include preceding valve seat 4 and rear valve base 5, and the rear valve base 5 is equipped with rectangular seal slot, the rectangular seal 6
It is contained in rectangular seal slot, the width of the rectangular seal 6 is more than the depth of rectangular seal slot so that rectangular seal 6
On there are certain interference volumes, the rectangular seal 6 to act against on the side of valve chamber 11, the valve plate 2 is between valve seat,
The side of the valve plate 2 is acted against on valve seat, and the valve seat is fixedly connected with support plate 3.
As shown in Figures 5 and 6, the utility model Novel valve seat centralizing tool includes screw rod 7 and is arranged on screw rod 7
Drag hook 8.The screw rod 7 includes the first end positioned at its left end and the second end positioned at its right end, the first end
And the second end is integrally formed, the first end is equipped with dextrorotation external screw thread, and the second end is equipped with sinistral external thread,
I.e. described first end is opposite with the external screw thread direction of rotation of the second end.The drag hook 8 sets there are two and sets respectively
Dextrorotation internal thread is equipped in the drag hook 8 on the first end and the second end, being arranged at first end, is arranged at second end
Drag hook 8 in portion is equipped with levogyrate inner thread, and the drag hook 8 is threadedly coupled with screw rod 7, and when screw rod 7 rotates, two drag hooks 8 can
