Description
Technical Field
The utility model relates to a sealed face grinding tool of self sealss valve wedge.
Background
At present, the high-pressure self-sealing valves all adopt a metal wedge-shaped sealing ring sealing structure, and the sealing rings are inverted triangular structures, so that the sealing rings are small in size and easy to deform, scratch damage and oxide skin are easily generated after operation, the sealing effect of the sealing rings is seriously influenced, two sealing surfaces of a valve core and a valve body which are matched with the sealing rings are restricted by an oblique angle and a position, the grinding and repairing requirements are high in precision, and the workload is large.
The grinding of the high-pressure self-sealing valve can not utilize a grinding electric machine to carry out grinding treatment at present, manual grinding and repairing are adopted, the technical standard is difficult to meet the requirements, the matching surfaces of the valve body and the valve core are generally manually ground by using oilstones and grinding wheel abrasive cloth, the smoothness, more mainly the roundness, of the valve body and the valve core can not be ensured, the wedge-shaped sealing ring is basically replaced, and the capital waste is caused. The red powder stamping inspection effect of the sealing surface is poor after the maintenance, the sealing line is not connected, and the hidden danger of steam leakage is easy to occur.
Disclosure of Invention
The utility model aims at providing a sealed face grinding tool of self sealss valve wedge.
The above purpose is realized by the following technical scheme:
a self-sealing valve wedge seal face grinding tool comprising: built-in mould, wedge sealing washer and valve body, the top and the adjustable rod of built-in mould be connected perpendicularly, the top and the operating handle of adjustable rod be connected perpendicularly, the adjustable rod with built-in mould between be connected with the skeleton and support, the face of adjustable rod on be connected with adjusting screw, built-in mould circumference seted up eight screw holes, and there is the lock solid screw at the downthehole screw in, the wedge sealing washer with the cell body of built-in mould between the cooperation.
The grinding tool for the wedge-shaped sealing surface of the self-sealing valve is characterized in that the inner grinding surface on the wedge-shaped sealing ring is matched with the outer wedge surface of the valve core of the valve body.
The utility model has the advantages that:
1. the utility model discloses a two sets of moulds cooperation are used, and when a plurality of valves were overhauld, one can realize that one grinds outer scarf, and wedge face in one grinds, alternate use raises the efficiency.
2. The utility model discloses can adjust or the less mould of suit along with valve internal diameter and abrasive surface degree of depth, adjust at any time, many places are general.
3. The utility model discloses when grinding, can carry out the adjustment correction that the wedge sealing washer gourd ladle warp partially, avoid changing the waste of new spare parts, continue to use the wedge circle, the matching degree is also higher. If the sand hole appears, when the mar is great, can carry out argon arc repair welding back, when polishing to slightly high 0.20mm about, use this frock mould to continue to grind, the impression inspection can guarantee whole week continuous seal line. Convenient adjustment, higher precision, good operability, safety and high efficiency.
4. The utility model discloses a combination kit tool designs and uses the back, can satisfy the self sealss maintenance grinding needs that the high pressure valve was installed to the production site, and application scope is wide, avoids manual hard-control volume of polishing and sealed face angle to receive the volume of polishing uneven and cause the disappearance to warp, can't reach whole laminating, guarantees sealed problem. After the clamping fixture is adjusted, the deformation of the wedge-shaped ring is within 0.05mm, so that the wedge-shaped ring and the corresponding matching surface are completely kept at an accurate fitting position, and the success rate is high. The problems of time and labor consumption and low efficiency in maintenance and poor safety are solved. Each machine can save 30 ten thousand yuan of outsourcing or returning funds.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
FIG. 2 is a schematic view of the built-in tire of FIG. 1 with an externally mountable wedge ring.
In the figure: 1. the inner-mounted type clamping fixture comprises an inner-mounted type clamping fixture, 2, a wedge-shaped sealing ring, 3, a valve body, 4, an adjustable rod, 5, an operating handle, 6, a framework support, 7, an adjusting screw, 8, a locking screw, 9, an inner grinding surface, 10 and a valve core outer wedge surface.
The specific implementation mode is as follows:
example 1:
a self-sealing valve wedge seal face grinding tool comprising: built-in mould 1, wedge sealing washer 2 and valve body 3, the top and the adjustable rod 4 of built-in mould be connected perpendicularly, the top and the 5 perpendicular connections of operating handle of adjustable rod, the adjustable rod with built-in mould between be connected with skeleton brace 6, the face of adjustable rod on be connected with adjusting screw 7, built-in mould circumference seted up eight screw holes, and the screw in has lock solid screw 8 in the screw hole, the wedge sealing washer with the cell body of built-in mould between the cooperation.
Example 2:
according to the grinding tool for the wedge-shaped sealing surface of the self-sealing valve in the embodiment 1, the inner grinding surface 9 on the wedge-shaped sealing ring is matched with the outer wedge surface 10 of the valve core of the valve body.
Example 3:
(1) because the valve seal structure part is inside the valve door body, it is great to be less than the valve gap faying face, large capacity high pressure valve can be less than about the door closure 500mm at the biggest in the valve, the space is narrow and small, and be interior dip angle structure, it is great to measure the maintenance grinding work degree of difficulty, at first, design one set can cooperate inside and outside micrometer to measure the mould of adjustment and wedge sealing washer cooperation suit, can carry out ladle inclined to one side and circularity adjustment through the adjusting screw, after fixed chucking, the combination structure degree of depth, design the adjustable operating handle that controls of installation, the cooperation cleaner, the grinding cream carries out the grinding work of two inboard sealed faces. As follows (fig. 1). Shown in
(2) According to the structural style of the first design, only the mould disc is changed, so that the mould can be externally provided with a wedge-shaped ring, the locking screw is adjusted to be arranged on the inner side, and the outer wedge surface of the wedge-shaped ring and the sealing matching surface in the valve body can be ground after assembly and adjustment. Also, the polishing work is performed by the use of a polishing paste or the like depending on the check adjustment. As shown in the following figure (fig. 2).
Claims (2)
1. A self-sealing valve wedge seal face grinding tool comprising: built-in mould, wedge sealing washer and valve body, characterized by: the top and the adjustable rod of built-in mould be connected perpendicularly, the top and the operating handle of adjustable rod be connected perpendicularly, the adjustable rod with built-in mould between be connected with the skeleton and support, the face of adjustable rod on be connected with adjusting screw, built-in mould circumference seted up eight screw holes, and the screw in has the lock solid screw in the screw hole, wedge sealing washer with the cell body of built-in mould between the cooperation.
2. The tool for grinding a wedge-shaped sealing surface of a self-sealing valve as claimed in claim 1, wherein: the inner grinding surface on the wedge-shaped sealing ring is matched with the outer wedge surface of the valve core of the valve body.
