Description

Universal tool for assembling valve seat

Technical Field

The utility model relates to an instrument, concretely relates to general assembly valve seat instrument.

Background

The development of the oil industry is different day by day, the demand of each large oil field at home and abroad on valves is very large, the demand of land oil fields is generally a single valve, an offshore platform is restrained by economy and space, the demand of a combination valve is large, the combination valve not only saves materials but also saves valuable space, the single valve is uniform in outer diameter Ø and length L according to the industrial standard and is shown in figure 1, when the single valve is assembled, a group of assembling tools with equal length are respectively arranged on the left side and the right side, as shown in figure 2, bosses on the tools on the two sides are clamped in an inner groove of the valve seat when the single valve is used, the valve seats on the two sides are respectively pulled to move backwards by rotating locking nuts on the tools, so that the distance between the two valve seats is increased, the valve plate can be smoothly assembled, and the tools need to be used in a set.

For the combination valve, as shown in fig. 3, it is formed by combining three single valves, and the positions of the valve seats are one, two and three as shown in the figure. For the valve seat assembly of these three places, three sets of tools with different lengths are needed, as shown in fig. 4, for the valve seats one and three, the assembling tools must be one long and one short, and have large differences, and the three sets of sizes are different, which causes inconvenience in processing, confusion in assembly and use, and great inconvenience in carrying and use if field maintenance operation is needed.

Disclosure of Invention

The utility model aims to provide a: the universal valve seat assembling tool is suitable for assembling the combined valves with the same drift diameter and the variable lengths.

The technical solution of the utility model is that: the general valve seat assembling tool comprises a left side baffle, a right side baffle and a long screw rod, wherein the left side baffle and the right side baffle which are parallel to each other are fixed by two bolts, and one end of the long screw rod is installed in the center of the right side baffle in a threaded mode.

Furthermore, the other end of the long screw is provided with a handle.

Furthermore, the thickness of vulcanized rubber on the surfaces of the left baffle and the right baffle is 2 mm.

Furthermore, the length of the long screw is determined according to the length of the valve and the combined valve.

The utility model has the advantages that:

1. the surface vulcanized rubber thickness of left side baffle, right side baffle is 2mm, laminates with both sides disk seat respectively, and rubber and disk seat surface contact separate its surface and metal effectively, play fine guard action.

2. The long screw rod with the handle is connected with the right baffle through threads, the handle is easily adjusted in distance at the back of the rotating screw rod, and when the distance is increased, the baffles on the two sides push the valve seat to be attached to the valve body.

3. Because the valve seat holes at the two ends of the combined valve are close to the end face, and the middle valve seat hole is far away from the end face, the length of the long screw rod only needs to meet the requirement of assembling the middle valve seat.

4. The tool is simple in structure, convenient to operate, free of maintenance and capable of being operated by only one person, is suitable for valves of the same specification (drift diameter) and different lengths, and is particularly suitable for assembling of combination valves.

Detailed Description

The technical scheme of the utility model is further explained in the following by combining the attached drawings.

As shown in fig. 5, the universal valve seat assembling tool comprises a left baffle plate 1, a right baffle plate 3 and a long screw rod 4, wherein the parallel left baffle plate 1 and the parallel right baffle plate 3 are fixed by two bolts 2, and one end of the long screw rod 4 is installed at the center of the right baffle plate 3 in a threaded manner.

Further, the other end of the long screw 4 is provided with a handle 5.

Furthermore, the thickness of the vulcanized rubber on the surfaces of the left baffle plate 1 and the right baffle plate 3 is 2 mm.

Further, the length of the long screw 4 is determined according to the length of the valve and the combination valve.

As shown in fig. 6, the valve seat assembly process is as follows:

1. according to the requirements of the figure, the cleaned valve seat is placed into the valve seat hole at the middle position, and the valve seat is ensured not to fall off in the valve cavity;

2. the valve body hole at the right end of the combined valve is stretched, when a tool is observed to stretch into the middle valve seat hole, the combined valve stops, the combined valve is slowly moved to enable the baffle plate with vulcanized rubber at the left side (one side of the rubber faces outwards) to be attached to the valve seat hole at the left side, and the transmission on a powerful tool is sensed; then slowly and clockwise rotating a handle at the top of the screw, and increasing the distance between the two baffles through the screw and the thread action on the right baffle, namely, the two valve seats are expanded;

3. when the two valve seats are expanded to a certain distance which is larger than the thickness of the valve plate, the valve plate is inserted at the moment, and the insertion depth of the valve plate reaches 1/3 of the diameter of the valve seats, the assembling tool is rotated anticlockwise, so that the baffles on the two sides of the tool are separated from contact with the baffles;

4. carefully moving the tool to the center of a channel hole of the combination valve, taking care not to collide with a valve seat, slowly drawing the tool to the right until the tool is completely separated from the combination valve;

and rotating the withdrawn tool through the screw rod to screw the baffle plates on the two sides together and removing impurities on the surfaces of the tool and the rubber for next reuse.

Claims

1. General assembly disk seat instrument, it includes left side baffle (1), right side baffle (3) and long screw (4), characterized by: the parallel left baffle (1) and the right baffle (3) are fixed by two bolts (2), and one end of a long screw (4) is installed at the center of the right baffle (3) in a threaded manner; the other end of the long screw rod (4) is provided with a handle (5); the vulcanized rubber on the outer surfaces of the left baffle (1) and the right baffle (3) has the thickness of 2 mm; the length of the long screw (4) is determined according to the length of the valve and the combined valve.
