Description

High pressure feed water heater entry union valve start tool

The technical field is as follows:

the utility model belongs to the technical field of extracting tool equipment, concretely relates to high pressure feed water heater entry allies oneself with and holds valve starting tool.

Background art:

the inlet connection valve of the high-pressure heater has the function that when the high-pressure heater leaks or the water level rises to a dangerous value, the high-pressure heater is protected to act, the electromagnetic valve is opened, pressure water from the condensate pump flows to the upper part of the piston of the inlet connection valve through the electromagnetic valve, the acting force of a spring at the lower part of the piston is overcome, the inlet connection valve is forcibly closed, and water inlet of the tube bundle of the high-pressure heater is stopped. After the high-pressure heater tube bundle stops feeding water, the pressure of the water fed by the tube bundle is released, the check valve at the outlet of the heater automatically falls down, the fed water directly flows to the boiler through the bypass, and meanwhile, the check valve is tightly pressed by the fed water, and the connection between the fed water and the heater tube bundle is cut off at the outlet side. The water supply bypass is automatically protected until the end. The problem of difficult opening of the valve rod due to jamming often occurs in the operation; the design of a water supply pipeline for starting a joint valve at the inlet of a high-pressure heater is small, and the phenomenon that a valve rod is difficult to open frequently occurs in the using process; the smoothness of the valve rod of the inlet connecting valve of the high-pressure heater is not enough, and finally the valve rod is difficult to lift. Therefore, it is necessary to design a special starting tool for the inlet connecting valve of the high-pressure heater, which is safe, reliable and convenient to use.

The utility model has the following contents:

the utility model aims at providing a safe, reliable and convenient to use special starting tool for a high-pressure heater inlet joint valve, which is processed by a 10mm steel plate, has extremely strong shock resistance and can ensure that the tool can not deform under any abnormal condition; the M24 bolt is used as the fulcrum of the adjusting lever, so that the bearing capacity is high, and the valve rod of the valve can not be damaged at various heights; the design of the inclined U-shaped socket enables the valve rod to be easily operated when the valve rod is at the lowest point. Simple operation, safety, reliability, simple structure, low cost, economy, applicability and easy popularization and use on a large scale.

The utility model adopts the technical proposal that: a starting tool for an inlet union valve of a high-pressure heater comprises a square starting head, a pipe handle and a supporting bolt; one end of the square opening head is provided with a U-shaped socket, the other end of the square opening head is welded with the pipe handle, and the square opening head is provided with a mounting hole; the supporting bolt is arranged on the mounting hole through two adjusting nuts positioned above and below the square opening head; the U-shaped socket and the mounting hole are positioned on the central line of the square opening head; the bottom end of the square opening head is provided with an inclined plane; the end part of the U-shaped socket is semicircular.

Furthermore, the thickness of the square opening head is 10mm, the length is 150mm, the width is 80mm, and the square opening head is made of a steel plate; the width of the U-shaped socket is 40mm, and the length of the U-shaped socket is 70 mm; the pipe handle is a steel pipe with the diameter of 25 mm.

Further, the diameter of the mounting hole is 26mm, and the support bolt penetrating through the mounting hole is an M24 bolt.

The utility model has the advantages that: the special starting tool for the inlet connecting valve of the high-pressure heater is safe, reliable and convenient to use, is processed by a 10mm steel plate, has extremely strong shock resistance, and can ensure that the special starting tool cannot deform under any abnormal condition; the M24 bolt is used as the fulcrum of the adjusting lever, so that the bearing capacity is high, and the valve rod of the valve can not be damaged at various heights; the design of the inclined U-shaped socket enables the valve rod to be easily operated when the valve rod is at the lowest point. Simple operation, safety, reliability, simple structure, low cost, economy, applicability and easy popularization and use on a large scale.

Description of the drawings:

FIG. 1 is a schematic top view of the first embodiment;

fig. 2 is a bottom view of fig. 1.

The specific implementation mode is as follows:

example one

Referring to fig. 1 and 2, a high pressure heater inlet union valve starting tool comprises a square starting head 1, a pipe handle 5 and a supporting bolt 4; one end of the square opening head 1 is provided with a U-shaped socket 2, the other end of the square opening head is welded with the pipe handle 5, and the square opening head 1 is provided with a mounting hole 8; the supporting bolt 4 is arranged on the mounting hole 8 through two adjusting nuts 6 positioned above and below the square opening head 1; the U-shaped socket 2 and the mounting hole 8 are positioned on the central line of the square opening head; the bottom end of the square opening head 1 is provided with an inclined plane 7; the end part of the U-shaped socket 2 is semicircular 3; the square opening head 1 is 10mm in thickness, 150mm in length and 80mm in width and is made of a steel plate; the width of the U-shaped socket 2 is 40mm, and the length of the U-shaped socket is 70 mm; the pipe handle 5 is a steel pipe with the diameter of 25 mm; the diameter of the mounting hole 8 is 26mm, and the support bolt 4 penetrating through the mounting hole 8 is an M24 bolt.

The starting tool is contacted with the valve rod through the U-shaped socket, the height of the fulcrum is adjusted by screwing the upper nut and the lower nut which are in threaded connection with the supporting bolt, and the valve rod of the inlet joint valve of the high-pressure heater is lifted by the aid of the pipe handle after the fulcrum is adjusted. The rapid opening of the inlet joint valve of the high-pressure heater can be realized through the tool, and the accident that the opening of the valve is too slow to cause instant water cut-off of the boiler is prevented. A nut for adjusting the height of the fulcrum is arranged on the tool; the fork-shaped design is adopted, so that the valve rod is not in rigid contact with the valve rod, and the valve rod is prevented from being damaged; the oblique iron type U-shaped socket can well probe into the valve rod.
