い欠点もあつた。 Conventionally, laminated packing made of inelastic materials such as asbestos or lead foil has been used for pipe joints such as fire extinguishing pipes, combustion exhaust gas pipes, combustion ash transport pipes, and steam pipes, but the sealing performance deteriorates over time. As a result, it is necessary to frequently retighten and replace the packing, which not only takes time and effort for maintenance, but also increases the size.
It has the disadvantages of high unit price and high maintenance and management costs, and in addition, it has relatively low sealing performance and the pipe joint cannot cope with the expansion and contraction caused by the thermal expansion of the pipe body, making it prone to breakage.

The entire outer peripheral surface of the packing body 42 is covered with a heat-resistant coating such as a cloth 44 made of carbon fiber or glass fiber, thereby improving the heat resistance of the packing body 42 made of a rubber-like elastic body. It is. This fabric 44 may be coated with heat-resistant ceramic powder to further improve its heat resistance, or the entire outer peripheral surface of the packing body 42 may be coated with a heat-resistant ceramic layer mixed with carbon fiber or glass fiber. You can.

23が形成されている。 An annular fluid reservoir 23 communicating with a fluid passage 22 within the pipe joint is formed in the flesh portion 21 of the joint mantle 4 surrounding the interior recess 14 in which the rubber packing 11 is placed.

ある。 The illustrated fluid storage chamber 23 has an interior recess 14,
It has a shape that surrounds it from the outer circumferential side and both front and rear sides, and also communicates with the inner cavity 25 of the rubber packing 11 having a U-shaped cross section through a notch 24 provided in the meat part 21. Of course, the shape of the reservoir chamber 23 may be any shape as long as it surrounds the interior recess 14 and can eliminate the influence of heat on the rubber packing 11 as described later.

送水機能を保持しうるものである。 In the above-described embodiment, when fire extinguishing water, etc. is fed through the connected pipes connected by pipe joints, the fire extinguishing water, etc. flows through the fluid storage chamber 23 and the fluid passage 2.
The fluid flows into the fluid storage chamber 23 and the inner cavity 25 of the rubber packing 11 through the communication port 26 with the rubber packing 11 . Therefore, even if flame etc. are blown from the outside of the pipe and the pipe joint becomes extremely hot, the interior recess 14 portion in which the rubber packing 11 is installed and the rubber packing 11 are cooled with fire extinguishing water, etc. This prevents deterioration and maintains the water supply function for a long time without deteriorating the sealing performance.

火用水の送水が不能となることはない。 As described above, since it has a double seal structure, even if the rubber packing 11 is thermally deformed and the sealing performance is deteriorated, the sealing performance is maintained by the rubber heat-resistant packing 36. Water supply for fire extinguishing purposes will not become impossible.
勿論、燃焼排ガス、燃焼灰あるいは蒸気等の輸

保持しうるものである。 Of course, good sealing performance can be maintained for a long period of time even in pipelines for transporting combustion exhaust gas, combustion ash, steam, etc.

吸収、消去し、各部の破損を防止する。 When the above-mentioned joint outer mantle pipe 4 and joint inner mantle pipe 8 have a joint structure as a pipe joint, the inner circumferential surface 9 of the joint mantle pipe 4 between the rubber packing 11 and the rubber heat-resistant packing 36 is The gap portion 39 between the outer circumferential surface 10 of the joint inner sleeve 8 and the annular groove 35 for an oil reservoir in the rubber packing 11 are as follows:
It is a part that stores lubricating oil 40, 41, and is used to prevent sliding when the fitting position of the joint outer pipe 4 and the joint inner mantle pipe 8 shifts relative to each other due to expansion and contraction of the connected pipes. It reduces dynamic resistance, improves sealing performance, absorbs and eliminates expansion and contraction due to thermal expansion of connected pipes, and prevents damage to various parts.

性、熱変形を防止でき、十分なシール性を保有し
うる効果を奏する。 The pipe joint according to the present invention has the configuration described above, and even if it is exposed to high heat from the outside of the joint for a long time when used as a pipe joint, the interior recess in which the rubber packing is installed will remain intact. Since the pipe is surrounded by a fluid reservoir filled with the fluid flowing through the pipe and is constantly cooled, the rubber packing can be prevented from thermal denaturation and deformation, and has the effect of maintaining sufficient sealing performance.
またゴム質パツキングが押圧され弾性変形する

撥弾性により、ゴム質パツキングをその当接面に
強く弾接させ、強いシール効果を生ずる効果があ
る。 Further, when the rubber packing is pressed and elastically deformed, the internal spring also deforms, and its repulsive elasticity brings the rubber packing into strong elastic contact with the contact surface, producing a strong sealing effect.

を助長する効果を奏する。 In addition, even if the packing body is thermally denatured and loses its elasticity due to being exposed to high heat for a long period of time, the rebound resilience of the spring will not be lost, so the packing body has a good sealing effect due to the rebound resilience of the spring. There are also effects that can last. That is, it is possible to prevent the thermal deformation of the packing body from becoming permanent. At this time, when the inner cavity is filled with air, oil, or a heat-resistant liquid substance, the thermal expansion force of these filled substances causes the packing body to bulge outward in the radial direction. It has the effect of promoting the sealing effect.

ても実用上支障のない程度のシール性を耐熱パツ
キングが保持しうるものである。 In addition, a rubber packing covered with a heat-resistant coating is installed in a position closer to the open end of the joint mantle than the rubber packing, so the rubber packing is also protected by the heat-resistant rubber packing and temporarily Even if the sealing performance of the rubber packing deteriorates, the heat-resistant packing can maintain a level of sealing performance that does not cause any practical problems.
更にゴム質パツキングはシール性の経時変化が
少ないので、パツキングの交換等は長期間行なう
必要がなく、価格も安いので、保守、管理の経費
を低くしうる効果もある。 Furthermore, since rubber packing has little change in sealing properties over time, there is no need to replace the packing over a long period of time, and since the price is low, maintenance and management costs can be reduced.
更に、ゴム質耐熱パツキングは、耐熱被覆で全
外周面が包被されているので、前記ゴム質パツキ

である。 Furthermore, since the entire outer circumferential surface of the rubber heat-resistant packing is covered with a heat-resistant coating, it has all the characteristics of the rubber packing, has excellent heat resistance, improves the sealing effect, and extends the service life. It is valid.

の損傷を防止しうる効果もある。 In addition, the annular groove formed in the rubber packing and the gap between the inner circumferential surface of the joint outer tube and the outer circumferential surface of the joint inner tube are used as lubricating oil reservoirs, so lubrication occurs here. When oil accumulates, the relative axial displacement between the inner and outer sleeves of the joint occurs smoothly, absorbing and eliminating the axial expansion and contraction of the pipe body due to the influence of heat, and also has the effect of preventing damage to various parts. be.
