Description

本発明は、例えば燃料電池発電装置の配管系に用いられる電磁弁に関するものである。   The present invention relates to an electromagnetic valve used in a piping system of a fuel cell power generator, for example.

近年、地球温暖化等の環境問題への対策として、商用電源から一般家庭等に供給される電気エネルギーの省電力化を図るため、燃料電池発電装置（例えば、特許文献１参照。）を用いた自家発電システムの開発が進められている。しかしながら、燃料電池発電装置では、燃料電池のスタックに多くの配管が接続されているため、組立作業及びメンテナンス作業が煩雑になるという問題がある。また、これらの配管は金属やゴム等からなるシール部材を介して継手により接続されているが、接続箇所が多いため流体の漏洩が生じやすく、長期的な使用での信頼性に劣るという問題もある。特に、燃料電池発電装置の配管には電磁弁が多く設けられるため、電磁弁に接続する配管も配管複雑化の要因の一つとなっている。   In recent years, as a countermeasure against environmental problems such as global warming, a fuel cell power generator (see, for example, Patent Document 1) has been used in order to save power of electric energy supplied from a commercial power source to a general household. In-house power generation systems are being developed. However, the fuel cell power generation apparatus has a problem that the assembly work and the maintenance work become complicated because many pipes are connected to the stack of fuel cells. In addition, these pipes are connected by joints through seal members made of metal, rubber, etc., but there are also problems that fluid leakage tends to occur due to the large number of connection points, resulting in poor reliability in long-term use. is there. In particular, since many solenoid valves are provided in the piping of the fuel cell power generation apparatus, piping connected to the solenoid valves is one of the causes of complicated piping.

そこで、電磁弁に接続される配管が一体に設けられたマニホールドに電磁弁を搭載することにより、配管接続箇所を少なくするとともに、組立工数や取付工数を低減して低コスト化を図るようにしている。
特開平６−２３１７９１号公報 特開２００１−２８９３５０号公報 Therefore, by mounting the solenoid valve on the manifold that is integrally provided with the pipe connected to the solenoid valve, the number of pipe connection points is reduced, and the assembly man-hours and installation man-hours are reduced to reduce costs. Yes.

ところで、前記マニホールドは金属製のブロックによって形成することも可能であるが、金属製のブロックでは流路が複雑になると容易に成形することができず、しかも金属製のブロックは高価であるため、低コストに製造することができない。そこで、樹脂材料を用いれば、複雑な流路を有する形状であっても容易に成形することができるが、樹脂材料は金属に比べて強度が低いため、電磁弁の弁座においては、弁体が繰り返し当接することにより破損を生じやすく、耐久性を低下させるという問題点があった。   By the way, the manifold can be formed by a metal block, but the metal block cannot be easily formed when the flow path becomes complicated, and the metal block is expensive. It cannot be manufactured at low cost. Therefore, if a resin material is used, it can be easily molded even if it has a shape having a complicated flow path. However, since the resin material has a lower strength than metal, a valve body is used in a valve seat of an electromagnetic valve. However, there is a problem that damage is easily caused by repeatedly contacting with each other and durability is lowered.

本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、マニホールドを低コストに製造することができるとともに、耐久性を低下させることのない電磁弁を提供することにある。   The present invention has been made in view of the above problems, and an object of the present invention is to provide an electromagnetic valve that can manufacture a manifold at a low cost and does not reduce durability. .

本発明は前記目的を達成するために、流体の流路を開閉する弁体が設けられた電磁弁本体と、流体の流路が一体に設けられ、所定の面に電磁弁本体が取付けられるマニホールドとを備え、マニホールドには電磁弁本体の弁体が当接する弁座を設けた電磁弁において、前記マニホールドを樹脂材料によって形成するとともに、弁座をマニホールドよりも硬質な材料よって形成している。   In order to achieve the above object, the present invention provides a solenoid valve body provided with a valve body for opening and closing a fluid flow path, and a manifold in which the fluid flow path is integrally provided and the solenoid valve body is attached to a predetermined surface. And the manifold is formed of a resin material and the valve seat is formed of a material harder than the manifold.

これにより、マニホールドが樹脂材料によって形成されることから、マニホールドを安価な材料によって容易に成形することができる。また、マニホールドに設けられる弁座がマニホールドよりも硬質な材料よって形成されることから、弁体が繰り返し当接しても弁座が容易に破損することがない。   Thereby, since the manifold is formed of a resin material, the manifold can be easily formed of an inexpensive material. Further, since the valve seat provided in the manifold is formed of a material harder than the manifold, the valve seat is not easily damaged even if the valve body repeatedly contacts.

本発明によれば、マニホールドを安価な材料によって容易に成形することができるので、製造コストの低減を図ることができる。この場合、弁体が繰り返し当接しても弁座が容易に破損することがないので、耐久性の向上を図ることができる。   According to the present invention, the manifold can be easily formed from an inexpensive material, so that the manufacturing cost can be reduced. In this case, even if the valve body repeatedly contacts, the valve seat is not easily damaged, so that durability can be improved.

図１及び図２は本発明の一実施形態を示すもので、図１は電磁弁の正面断面図、図２はその正面分解断面図である。   1 and 2 show an embodiment of the present invention. FIG. 1 is a front sectional view of a solenoid valve, and FIG. 2 is a front exploded sectional view thereof.

この電磁弁は、電磁弁本体１０と、電磁弁本体１０が取付けられるマニホールド２０とからなり、例えば燃料電池発電装置の配管に設けられるものである。   This electromagnetic valve includes an electromagnetic valve main body 10 and a manifold 20 to which the electromagnetic valve main body 10 is attached. For example, the electromagnetic valve is provided in a pipe of a fuel cell power generator.

電磁弁本体１０は上下方向に移動自在なプランジャ１１を備え、プランジャ１１はスプリング１２によって下方に付勢されるとともに、電磁コイル１３によって上方のコア１４に吸着されるようになっている。プランジャ１１の下端には弁体１５が設けられ、弁体１５はマニホールド２０に設けられる弁座に当接するようになっている。   The solenoid valve body 10 includes a plunger 11 that is movable in the vertical direction. The plunger 11 is biased downward by a spring 12 and is attracted to an upper core 14 by an electromagnetic coil 13. A valve body 15 is provided at the lower end of the plunger 11, and the valve body 15 comes into contact with a valve seat provided in the manifold 20.

マニホールド２０は、上面を開口した流体流通室２１と、一端側を流体流通室２１の底面側に連通する二つの流路２２と、各流路２２の他端側にそれぞれ設けられた配管接続部２２ａとを一体に有し、射出成形等によって樹脂材料から成形されている。流体流通室２１内の底面側には弁体１５が当接する弁座２３が設けられ、弁座２３は一方の流路２２の一端側に設けられている。弁座２３は、例えばステンレス鋼、銅合金等の金属製の円筒状部材からなり、その上端面は径方向外側に向かって下り傾斜をなすようにテーパ状に形成されている。弁座２３は流体流通室２１に設けられた凹部２１ａに嵌合することによって取付けられており、凹部２１ａの内周面と弁座２３の外周面との間にはゴム製のＯリングからなるシール部材２４が設けられている。また、マニホールド２０の上面にはゴム製のＯリングからなるシール部材２５が設けられ、シール部材２５は流体流通室２１の開口部の周囲に配置されている。   The manifold 20 includes a fluid flow chamber 21 having an open top surface, two flow paths 22 having one end side communicating with the bottom surface side of the fluid flow chamber 21, and pipe connection portions provided on the other end side of each flow path 22, respectively. 22a and is molded from a resin material by injection molding or the like. A valve seat 23 with which the valve body 15 abuts is provided on the bottom surface side in the fluid circulation chamber 21, and the valve seat 23 is provided on one end side of one flow path 22. The valve seat 23 is made of a cylindrical member made of metal such as stainless steel or copper alloy, and the upper end surface thereof is formed in a tapered shape so as to be inclined downward toward the radially outer side. The valve seat 23 is attached by being fitted into a recess 21 a provided in the fluid circulation chamber 21, and is composed of a rubber O-ring between the inner peripheral surface of the recess 21 a and the outer peripheral surface of the valve seat 23. A seal member 24 is provided. A seal member 25 made of a rubber O-ring is provided on the upper surface of the manifold 20, and the seal member 25 is disposed around the opening of the fluid circulation chamber 21.

以上の構成においては、マニホールド２０の上面に図示しないボルトによって電磁弁本体１０が取付けられ、流体流通室２１の上面開口部が電磁弁本体１０の底面によって閉塞されるとともに、電磁弁本体１０の底面とマニホールド２０の上面との間がシール部材２５によって密閉される。その際、プランジャ１１の下端側が流体流通室２１内に位置し、プランジャ１１の弁体１５が流体流通室２１内の弁座２３に当接する。   In the above configuration, the solenoid valve main body 10 is attached to the upper surface of the manifold 20 with a bolt (not shown), the upper surface opening of the fluid circulation chamber 21 is blocked by the bottom surface of the solenoid valve main body 10, and the bottom surface of the solenoid valve main body 10. And the upper surface of the manifold 20 are sealed by a seal member 25. At that time, the lower end side of the plunger 11 is located in the fluid circulation chamber 21, and the valve body 15 of the plunger 11 contacts the valve seat 23 in the fluid circulation chamber 21.

前記電磁弁においては、電磁コイル１３に通電してプランジャ１１をコア１４に吸着すると、弁体１５が弁座２３から上方に移動して一方の流路２２が開放され、一方の流路２２と他方の流路２２とが流体流通室２１を介して連通し、各流路２２を流体が流通する。また、電磁コイル１３の通電を解除すると、スプリング１２によって弁体１５が弁座２３に当接し、一方の流路２２が閉鎖されて各流路２２間の流体の流通が遮断される。   In the electromagnetic valve, when the electromagnetic coil 13 is energized and the plunger 11 is attracted to the core 14, the valve body 15 moves upward from the valve seat 23 to open one flow path 22, The other channel 22 communicates with each other through the fluid circulation chamber 21, and the fluid flows through each channel 22. When the energization of the electromagnetic coil 13 is released, the valve body 15 is brought into contact with the valve seat 23 by the spring 12, the one flow path 22 is closed, and the fluid flow between the flow paths 22 is blocked.

本実施形態によれば、一対の流路２２を一体に有するマニホールド２０を樹脂材料によって形成したので、マニホールド２０を安価な材料によって容易に成形することができ、製造コストの低減を図ることができる。この場合、マニホールド２０側に設けられる弁座２３を金属製の部材によって形成したので、弁体１５が繰り返し当接しても弁座２３が容易に破損することがなく、耐久性の向上を図ることができる。   According to the present embodiment, since the manifold 20 integrally including the pair of flow paths 22 is formed of the resin material, the manifold 20 can be easily formed of an inexpensive material, and the manufacturing cost can be reduced. . In this case, since the valve seat 23 provided on the manifold 20 side is formed of a metal member, the valve seat 23 is not easily damaged even when the valve body 15 repeatedly contacts, and durability is improved. Can do.

また、弁座２３を筒状の部材によって形成し、マニホールド２０に設けた凹部２１ａに嵌合するようにしたので、弁座２３をマニホールド２０に確実に取付けることができる。この場合、弁座２３と凹部２１ａとの間にシール部材２４を設けたので、弁座２３とマニホールド２０との間を確実に密閉することができ、流体の漏洩防止に効果的である。   Further, since the valve seat 23 is formed of a cylindrical member and is fitted into the recess 21 a provided in the manifold 20, the valve seat 23 can be securely attached to the manifold 20. In this case, since the sealing member 24 is provided between the valve seat 23 and the recess 21a, the valve seat 23 and the manifold 20 can be reliably sealed, which is effective in preventing fluid leakage.

尚、前記実施形態では、弁座２３を金属製の部材によって形成したものを示したが、マニホールド２０の樹脂材料よりも硬質な部材であれば、例えばフェノール、ポリエステル等の熱硬化性樹脂や、ＰＰＳ（ポリフェニレンサルファイド）、ＰＩ（ポリイミド）、ＰＥＥＫ（ポリエーテルエーテルケトン）、ＰＥＳ（ポリエーテルサルホン）等の熱可塑性樹脂、或いはカーボン繊維、タルク、カーボン粉等で強化された樹脂を用いることも可能である。   In the above embodiment, the valve seat 23 is formed of a metal member. However, if the member is harder than the resin material of the manifold 20, for example, a thermosetting resin such as phenol or polyester, It is also possible to use a thermoplastic resin such as PPS (polyphenylene sulfide), PI (polyimide), PEEK (polyether ether ketone), PES (polyether sulfone), or a resin reinforced with carbon fiber, talc, carbon powder or the like. Is possible.

また、前記実施形態では、弁座２３と凹部２１ａとの間をシール部材２４で密閉したものを示したが、溶着等によって一体化して密閉するようにしてもよい。   Moreover, in the said embodiment, although what sealed between the valve seat 23 and the recessed part 21a with the sealing member 24 was shown, you may make it integrate and seal by welding etc. FIG.
