本考案は塗装ラインで用いられる水性塗料用レギュレータ、特に、ケーシング に、塗料収容室と、その塗料収容室に対し制御弁を介して連通または遮断される 流入口と、前記塗料収容室に連通する流出口とをそれぞれ設け、前記制御弁は前 記ケーシングに設けられた弁座と、前記塗料収容室内の塗料圧が設定値よりも高 いとき前記弁座に着座し、一方、低いとき前記弁座から離間する弁体とを有する 水性塗料用レギュレータの改良に関する。 The present invention relates to a water-based paint regulator used in a painting line, particularly to a casing, a paint storage chamber, an inlet for communicating with or shutting off from the paint storage chamber via a control valve, and the paint storage chamber. An outlet is provided for each of the control valves, and the control valve is seated on the valve seat provided on the casing, and when the paint pressure in the paint storage chamber is higher than a set value, the control valve is seated on the valve seat. The present invention relates to an improvement of a regulator for water-based paint having a valve body separated from a seat.
【０００２】[0002]
この種レギュレータにおいては、塗装ガン等の塗装機器への塗料供給圧を一定 に保つため、弁体が弁座に対し着座および離間を頻繁に繰返すため、弁体および 弁座の耐久性が低い場合には弁体および／または弁座が短時間のうちに破損して シール性が損われ、制御弁は調圧機能を失うことになる。この調圧機能は弁体お よび／または弁座への塗料かすの堆積によっても低下する。 In this type of regulator, when the supply pressure of the paint to the coating equipment such as the coating gun is kept constant, the valve body frequently sits on and separates from the valve seat, so the durability of the valve body and valve seat is low. The valve body and / or the valve seat will be damaged in a short time and the sealing performance will be impaired, and the control valve will lose the pressure regulating function. This pressure regulation function is also deteriorated by the accumulation of paint dregs on the valve body and / or valve seat.
【０００３】 そこで、前記不具合を解消し得るレギュレータとして、弁座を超硬合金、例え ばＧ３型超合金より構成し、また弁体をセラミックス、例えば部分安定化ジルコ ニア（ＰＳＺ）より構成したものが開発されている（実開平４−２７２７４号公 報参照）。Therefore, as a regulator capable of eliminating the above-mentioned inconvenience, a valve seat made of cemented carbide, for example, G3 type superalloy, and a valve body made of ceramics, for example, partially stabilized zirconia (PSZ) Has been developed (refer to the official report of No. 4-27274).
【０００４】[0004]
前記従来のレギュレータによれば、弁座および弁体の耐久性が高く、またそれ らに対する塗料かすの堆積もないため、調圧機能保持時間を飛躍的に延ばすこと ができるが、Ｇ３型超硬合金およびＰＳＺは特殊材料であることから非常に高価 である。そこで部品価格低減上、安価で、且つ前記のような特性を持つ材料より なる弁座および弁体を備えたレギュレータの開発が望まれていた。 According to the conventional regulator, the valve seat and the valve body have high durability and there is no buildup of paint debris on them, so that the time for holding the pressure regulating function can be dramatically extended. Alloys and PSZ are very expensive because they are special materials. Therefore, in order to reduce the cost of parts, it has been desired to develop an inexpensive regulator having a valve seat and a valve body made of a material having the above-mentioned characteristics.
【０００５】 本考案は、このような現状に鑑みて開発されたものであって、弁座の弁体着座 部および弁体を比較的安価な材料より構成し、しかも性能は従来の場合と同等で ある前記レギュレータを提供することを目的とする。The present invention was developed in view of such a situation as described above. The valve seat and the valve body of the valve seat are made of a relatively inexpensive material, and the performance is equivalent to that of the conventional case. It is an object of the present invention to provide the regulator.
【０００６】[0006]
本考案に係る水性塗料用レギュレータは、前記弁座の弁体着座部を、光散乱法 により測定された平均分子量Ｍｗが３００万≦Ｍｗ≦５００万である超高分子量 ポリエチレンより構成し、前記弁体をステンレス鋼より構成したことを特徴とす る。 In the regulator for water-based paint according to the present invention, the valve body seat portion of the valve seat is made of ultra-high molecular weight polyethylene having an average molecular weight Mw measured by a light scattering method of 3,000,000 ≦ Mw ≦ 5,000,000, The body is made of stainless steel.
【０００７】[0007]
前記平均分子量Ｍｗを有する超高分子量ポリエチレンは、その巨大分子量に起 因して、優れた物理的強度および化学的安定性を備え、特に耐摩耗性、自己潤滑 性、耐衝撃性、耐薬品性、撥水性に優れ、また塗料かすに対して非付着能を発揮 し、その上切削加工も容易である。 The ultra-high-molecular-weight polyethylene having the above-mentioned average molecular weight Mw has excellent physical strength and chemical stability due to its macromolecular weight, and particularly has excellent wear resistance, self-lubrication, impact resistance, and chemical resistance. It has excellent water repellency, exhibits non-adhesiveness to paint residue, and is easy to cut.
【０００８】 このような特性を有する超高分子量ポリエチレンより弁座の弁体着座部を構成 し、これとステンレス鋼より構成された弁体とを組合せると、それらは優れた耐 久性を発揮すると共にそれらに対する塗料かすの堆積が回避され、これによりレ ギュレータは長期に亘って調圧機能を持続する。When the valve body seating portion of the valve seat is made of ultra-high molecular weight polyethylene having such characteristics, and when this is combined with the valve body made of stainless steel, they exhibit excellent durability. In addition, the buildup of paint dregs on them is avoided, which allows the regulator to maintain its pressure regulating function for a long time.
【０００９】 ただし、平均分子量ＭｗがＭｗ＜３００万では超高分子量ポリエチレンの物理 的強度および化学的安定性が低下し、一方、Ｍｗ＞５００万では超高分子量ポリ エチレンの耐衝撃性が低下する。However, when the average molecular weight Mw is Mw <3,000,000, the physical strength and chemical stability of the ultrahigh molecular weight polyethylene are lowered, while when Mw> 5,000,000, the impact resistance of the ultrahigh molecular weight polyethylene is lowered. .
【００１０】 超高分子量ポリエチレンとしては、前記特性上、平均分子量Ｍｗが３５０万≦ Ｍｗ≦４５０万であるものが好適である。As the ultra high molecular weight polyethylene, those having an average molecular weight Mw of 3.5 million ≦ Mw ≦ 4.5 million are preferable in view of the above characteristics.

Always abuts 16.
【００１５】 キャップ８に、作動ロッド１８と同軸上に位置するように、調圧つまみ２０が 螺合され、その先端部はばね収容室８内に位置する。ばね収容室８内において、 調圧つまみ２０の先端部が当接するリテーナ２１とダイヤフラム６に取付けられ たリテーナ２２との間に調圧ばね２３が縮設されている。２４はハウジング本体 ４に螺着された圧力計である。A pressure adjusting knob 20 is screwed into the cap 8 so as to be positioned coaxially with the actuating rod 18, and the tip end portion thereof is positioned in the spring accommodating chamber 8. In the spring accommodating chamber 8, a pressure adjusting spring 23 is contracted between a retainer 21 with which the tip of the pressure adjusting knob 20 abuts and a retainer 22 attached to the diaphragm 6. Reference numeral 24 is a pressure gauge screwed to the housing body 4.
【００１６】 図２に明示するように、弁座１５は弁座本体２５と、それと一体化された中空 筒２６とより構成される。弁座本体２５はボルト状に形成されており、流入口９ 内に位置する六角頭部２７と、その六角頭部２７に突設されて環状壁１４に螺着 されたねじ軸部２８とよりなる。また弁座本体２５は軸方向に延びる貫通孔２９ を有し、その貫通孔２９は塗料収容室７側の小径部３０と弁体１６側の大径部３ １とよりなる。その大径部３１に中空筒２６が圧入され、中空筒２６の孔部３２ と小径部３０とにより弁孔１９が形成される。したがって、中空筒２６の流入口 ９側の端部が弁体着座部３３として機能する。As clearly shown in FIG. 2, the valve seat 15 is composed of a valve seat body 25 and a hollow cylinder 26 integrated with the valve seat body 25.

Further, the valve seat main body 25 has a through hole 29 extending in the axial direction, and the through hole 29 is composed of a small diameter portion 30 on the paint containing chamber 7 side and a large diameter portion 31 on the valve body 16 side. The hollow cylinder 26 is press-fitted into the large diameter portion 31, and the valve hole 19 is formed by the hole 32 and the small diameter portion 30 of the hollow cylinder 26. Therefore, the end portion of the hollow cylinder 26 on the inflow port 9 side functions as the valve body seating portion 33.
【００１７】 弁座本体２５はステンレス鋼、本実施例ではＪＩＳ ＳＵＳ３１６より構成さ れる。また弁体１６もステンレス鋼より構成され、その鋼種としては、ステンレ ス鋼において最も硬さの高いＪＩＳ ＳＵＳ４４０Ｃが選択される。The valve seat body 25 is made of stainless steel, JIS SUS316 in this embodiment.

【００１８】 中空筒２６は、超高分子量ポリエチレンより構成され、その平均分子量Ｍｗは 、光散乱法による測定値において３００万≦Ｍｗ≦５００万である。The hollow cylinder 26 is made of ultra high molecular weight polyethylene, and its average molecular weight Mw is 3,000,000 ≦ Mw ≦ 5,000,000 as measured by a light scattering method.
【００１９】 このような平均分子量Ｍｗを有する超高分子量ポリエチレンは、その巨大分子 量に起因して、優れた物理的強度および化学的安定性を備え、特に耐摩耗性、自 己潤滑性、耐衝撃性、耐薬品性、撥水性に優れ、また塗料かすに対して非付着能 を発揮し、その上切削加工も容易である。The ultra-high-molecular-weight polyethylene having such an average molecular weight Mw has excellent physical strength and chemical stability due to its macromolecular weight, and particularly wear resistance, self-lubricity, and resistance to abrasion.

【００２０】 本実施例においては、超高分子量ポリエチレンとして、市販の平均分子量Ｍｗ がＭｗ＝４００万であるＳａｎｉｎ ニューライト（作新工業社製、商品名）が 用いられた。In this example, as the ultra-high molecular weight polyethylene, Sanin Newlite (trade name, manufactured by Sakushin Kogyo Co., Ltd.) having a commercially available average molecular weight Mw of Mw = 4,000,000 was used.
【００２１】 次に、レギュレータ１の作動について説明する。Next, the operation of the regulator 1 will be described.
【００２２】 塗装機器への塗料供給圧、したがって塗料収容室７内の塗料圧の設定に当って は、調圧つまみ２０を回してその先端側をばね収容室８内に所定量進入させ、調 圧ばね２３の弾発力によってダイヤフラム６を塗料収容室７側へ撓ませる。これ により作動ロッド１８が前進して弁体１６を押すので、弁体１６が弁座１５の弁 体着座部３３から離間して弁孔１９が開放される。In setting the paint supply pressure to the coating equipment, and hence the paint pressure in the paint accommodating chamber 7, the pressure adjusting knob 20 is rotated to move the tip end side thereof into the spring accommodating chamber 8 by a predetermined amount to adjust the pressure. The elastic force of the pressure spring 23 causes the diaphragm 6 to bend toward the paint storage chamber 7 side. As a result, the operating rod 18 advances and pushes the valve body 16, so that the valve body 16 is separated from the valve body seating portion 33 of the valve seat 15 and the valve hole 19 is opened.
【００２３】 塗料供給源よりジョイント金具１２の塗料通路１３を経て流入口９に供給され た水性塗料は、弁孔１９から塗料収容室７に導入され、次いで流出口１０から塗 装機器に向けて供給される。塗料収容室７内の塗料圧が設定値、即ち調圧ばね２ ３のセット荷重よりも低いときには前記のように弁体１６が弁座１５の弁体着座 部３３から離間して弁孔１９が開放状態に保持されるので、流入口９から流出口 １０への水性塗料の供給が続行される。The water-based paint supplied from the paint supply source to the inflow port 9 through the paint passage 13 of the joint fitting 12 is introduced into the paint storage chamber 7 through the valve hole 19, and then from the outflow port 10 toward the coating device. Supplied. When the paint pressure in the paint accommodating chamber 7 is lower than the set value, that is, the set load of the pressure regulating spring 23, the valve body 16 is separated from the valve body seating portion 33 of the valve seat 15 as described above, and the valve hole 19 is formed. Since the open state is maintained, the supply of the aqueous coating material from the inflow port 9 to the outflow port 10 is continued.
【００２４】 塗料収容室７内の塗料圧が高くなり、それが調圧ばね２３のセット荷重を超え ると、ダイヤフラム６がばね収容室８側へ撓むので作動ロッド１８が後退し、こ れに伴い弁ばね１７の弾発力で弁体１６が弁座１５の弁体着座部３３に着座して 弁孔１９を閉鎖する。When the paint pressure in the paint accommodating chamber 7 becomes higher and exceeds the set load of the pressure regulating spring 23, the diaphragm 6 bends toward the spring accommodating chamber 8 side, and the operating rod 18 retracts. Accordingly, the valve element 16 is seated on the valve element seating portion 33 of the valve seat 15 by the elastic force of the valve spring 17 to close the valve hole 19.
【００２５】 塗装機器による水性塗料の消費により塗料収容室７内の塗料圧が調圧ばね２３ のセット荷重よりも低くなると、ダイヤフラム６が塗料収容室７側へ撓むので弁 体１６が弁座１５の弁体着座部３３から離間して弁孔１９が再び開放される。When the paint pressure in the paint accommodating chamber 7 becomes lower than the set load of the pressure adjusting spring 23 due to the consumption of the water-based paint by the painting equipment, the diaphragm 6 bends toward the paint accommodating chamber 7 side, so that the valve body 16 is seated. The valve hole 19 is opened again while being separated from the valve body seating portion 33 of 15.
【００２６】 このように弁体１６が弁座１５の弁体着座部３３に対して着座および離間を頻 繁に繰返すことにより、塗装機器への塗料供給圧が一定に保持される。As described above, the valve body 16 frequently repeats seating and separation with respect to the valve body seating portion 33 of the valve seat 15, whereby the paint supply pressure to the coating equipment is kept constant.
【００２７】 水性塗料として、アクリルエマルジョン系水性塗料を用い、また流入口９にお ける塗料流入圧を８〜１０kg／cm2 に設定し、さらに塗料収容室７における設定 塗料圧を３〜６kg／cm2 に規定し、さらにまた弁座１５の弁体着座部３３および 弁体１６の材質を変えて、前記同様にレギュレータ１を作動させ、弁体着座部３ ３および弁体１６における塗料かすの堆積状況および調圧機能保持時間を調べた ところ、表１の結果を得た。As the water-based paint, an acrylic emulsion-based water-based paint is used, the paint inflow pressure at the inflow port 9 is set to 8 to 10 kg / cm 2 , and the paint pressure set in the paint storage chamber 7 is set to 3 to 6 kg / defined cm 2, furthermore changing the material of the valve body seat 33 and the valve body 16 of the valve seat 15, in the same manner as described above to operate the regulator 1, the paint sludge in the valve body seat 3 3 and the valve body 16 The results of Table 1 were obtained when the deposition status and the pressure control function holding time were examined.

Since they are combined, they exhibit excellent durability and avoid the accumulation of paint residue on them, which allows the regulator 1 to maintain the pressure regulating function for a long period of time, and its performance is equivalent to the conventional example. . Moreover, the embodiment is less expensive than the conventional example due to the material of the valve seat portion 33 and the valve body 16. Comparative Example 1 was carried out because the average molecular weight Mw of ultrahigh molecular weight polyethylene was Mw <3,000,000, while Comparative Example 2 was performed because the average molecular weight Mw of ultrahigh molecular weight polyethylene was Mw> 5,000,000. The performance is significantly reduced as compared with the example and the conventional example.
