しての耐久性の向上を図るものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field and Outline of the Invention] The present invention relates to a gas cock, and it is difficult for the grease intervening in the sliding portion between the gas cock body and the plug body to cause grease breakage. In this way, it is possible to prevent galling between the gas cock body and the plug body and to improve the durability of the gas cock.

外周面を栓体収容室(10)の内周面に圧接させ、これら
相互間のシール性を確保している。[Prior Art and its Problems and Technical Problems] Generally, as shown in FIG. 3, a gas cock has an inverted cone that is rotated by an operation shaft in a plug housing chamber (10) of a gas cock body (1). A trapezoidal plug body (2) is housed in a paired state around it, and the outer peripheral surface of the plug body (2) is formed by urging the plug body (2) toward the reduced diameter side with a spring or the like. Is pressed against the inner peripheral surface of the plug accommodating chamber (10) to ensure the sealing property between them.
従って、ガスコックの開閉は、栓体収容室(10)の内
周面とこれと圧接状態にある栓体(2)の外周面とを摺

回数の増加に伴なって摺動面が損傷し、遂には、所謂ガ
ジリ付き現象が発生する。即ち、栓体(2)が回動不能
となり、ガスコックとしての開閉操作ができなくなる。Therefore, the opening and closing of the gas cock is performed in such a manner that the inner peripheral surface of the stopper housing chamber (10) and the outer peripheral surface of the stopper body (2) in pressure contact therewith are slid, and as a result, the number of times the gas cock is operated. As a result, the sliding surface is damaged, and finally a phenomenon called gazing occurs. That is, the stopper (2) becomes unrotatable, and the gas cock cannot be opened / closed.
そこで、上記問題を解決する為に、一般には、栓体収
容室(10)と栓体(2)との摺動面にグリス膜を形成さ
せ、前記摺動面の摩擦力を減少させている。Therefore, in order to solve the above problem, generally, a grease film is formed on the sliding surface between the plug housing chamber (10) and the plug (2) to reduce the frictional force of the sliding surface. .
ところが、従来のものでは、上記対策を講じても、あ
まり、ガスコックの耐久性の向上が図れないと言う問題
がある。However, the conventional one has a problem that the durability of the gas cock cannot be improved so much even if the above measures are taken.
これは、栓体(2)の外周面と栓体収容室(10)の内
周面との間に形成されたグリス膜が、栓体(2)の回動
操作に伴なって、薄くなったり、不均一になり易いこと
がその原因となっている。This is because the grease film formed between the outer peripheral surface of the plug body (2) and the inner peripheral surface of the plug body housing chamber (10) becomes thinner as the plug body (2) is rotated. The cause is that it tends to be uneven.

は、ガスコックが十分な耐久性を有しないのである。In more detail about the above-mentioned cause, in the above-mentioned conventional one, the sliding surfaces of the plug body (2) and the plug body housing chamber (10) for housing the same are smooth surfaces in order to reduce the sliding resistance between them. Is formed in. Therefore, the grease applied to these smooth surfaces is difficult to be stably held on the smooth surfaces, and by repeating the rotating operation of the plug body (2), the grease is removed from the plug body (2) and the plug body accommodating chamber. The amount of grease that gradually protrudes from the sliding surface of (10) and intervenes on the sliding surface is reduced. Then, if the gas cock is further used in this state, the reduced grease further decreases and finally the grease becomes insufficient, and the frictional force generated when the gas cock body (1) and the plug body (2) slide is increased. As a result, galling easily occurs between them. From this, in the above-mentioned conventional one, the gas cock does not have sufficient durability.

Improvement of durability in "a method for manufacturing a gas cock in which a stopper body (2) rotated by an operation shaft is housed in a paired state in a stopper housing chamber (10) of a gas cock body (1)" To prevent this, the sliding surfaces of the gas cock body (1) and the plug body (2) are made less likely to run out of grease, and even if a state close to running out of grease should occur, It is an object of the present invention to make it possible to more surely enable rotation.
[技術的手段] 上記技術的課題を解決する為に講じた本発明の技術的
手段は、『ガスコック本体(1)及び栓体(2)を共に

The surface of the is finished and cut by Superoll processing, and the stopper body (2) is housed in a paired state around the stopper body accommodating chamber (10) of the gas cock body (1) with a sealing grease interposed. That's it.
[作用] 上記技術的手段は次のように作用する。[Operation] The above technical means operates as follows.
ガスコック本体(1)及び栓体(2)は共に鉄製で栓

栓体(2)の表面に保持されるグリス量が多くなるので
ある。Both the gas cock body (1) and the plug body (2) are made of iron, and a metal sprayed layer (K) is formed on the outer surface of the plug body (2).
However, since the metal sprayed layer (K) is essentially porous, when grease is applied to the porous surface, it penetrates into the metal sprayed layer (K). That is,
The amount of grease retained on the surface of the stopper (2) increases.
従って、ガスコックの開閉、即ち、栓体(2)の回動
操作に伴なって、グリスが栓体収容室(10)と栓体
(2)との間から流出しても、上記多孔質の金属溶射層
(K)にグリスが浸透保持せしめられているから、これ
ら両者の摺動面がグリス不足を起こし難くなる。Therefore, even if the grease flows out from between the plug body accommodating chamber (10) and the plug body (2) as the gas cock is opened and closed, that is, the plug body (2) is rotated, Since grease is permeated and held in the metal sprayed layer (K), it becomes difficult for the sliding surfaces of both of them to cause insufficient grease.

(K)(K)相互が摺動する場合に比べて摺動抵抗が少
なくなる。The thermal spray material used for metal spraying is a relatively soft material containing copper such as bronze as a main component. Due to some abnormality between the surface of the stopper housing portion (10) of the iron cock body (1) and the metal sprayed layer (K) of the stopper (2), the state becomes almost like running out of grease, and the two are Even if they are in direct contact with each other, the iron surface of the plug housing (10) having high hardness and the metal sprayed layer (K) that is softer than this slide against each other. The sliding resistance is reduced as compared with the case where the layers (K) and (K) slide with each other.

る。Since the surface of the metal sprayed layer (K) is finally cut and then finished by Superoll processing, the tops of the fine projections formed by metal spraying are the surfaces plastically deformed into fine curved surfaces by the roll of the Superoll processing tool. Become. The discontinuous surface of this plastically deformed surface becomes a paired surface around the gas cock body and the plug body (2). Accordingly, since the fine convex portions having sharpened peripheral pair surfaces do not form a continuous surface state, the sliding resistance also decreases in this respect.
[効果] 本発明は上記構成であるから次の特有の効果を有す
る。[Effects] The present invention having the above-described configuration has the following unique effects.
栓体収容室(10)と栓体(2)の摺動面がグリス不足

(2)が直接接触してその摺動面が損傷を受け難くな
る。従って、上記技術的手段を採用した本発明のガスコ
ックの場合、該コックの耐久性の向上が図れる。Since the sliding surfaces of the stopper housing chamber (10) and the stopper body (2) are unlikely to cause insufficient grease, the sliding surface is damaged by direct contact between the stopper body housing chamber (10) and the stopper body (2). It becomes difficult to receive. Therefore, in the case of the gas cock of the present invention which adopts the above technical means, the durability of the cock can be improved.
グリス切れに近いようなグリス不足が生じたとして

(K)との摺動抵抗が、鉄製摺動面相互及び金属溶射層
(K)(K)相互が摺動する場合に比べて摺動抵抗が少
なくなるから、前記異常時においても栓体(2)が回動
不能となりにくい。Even if a grease shortage, which is close to running out of grease, occurs, the sliding resistance between the surface of the plug housing (10) and the metal sprayed layer (K) on the surface of the plug is such that the sliding surfaces made of iron and the metal sprayed layer. (K) Since the sliding resistance is smaller than that when (K) slides against each other, the plug body (2) is less likely to be unable to rotate even in the case of the above abnormality.

向上したものとなる。Further, when the surface of the plug body (2) is viewed in detail, the surface of the metal sprayed layer (K) has a fine curved surface in which the tops of the sharp projections are plastically deformed. Since the entire body surface is in such a surface state, the above effect is further improved.
[実施例] 以下、本発明の実施例を第1図及び第2図に基づいて
説明する。[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
この実施例のものは、第1図に示すように、既述従来
例のガスコックとほぼ同様の構成であるが、ガスコック
本体(1)及び栓体(2)をともに鋳鉄で構成し、前記
栓体(2)の外周壁にのみ金属溶射層(K)を形成させ
たものである。As shown in FIG. 1, this embodiment has substantially the same structure as the gas cock of the above-mentioned conventional example, but the gas cock body (1) and the plug body (2) are both made of cast iron, The metal sprayed layer (K) is formed only on the outer peripheral wall of the body (2).
このものは、溶射材料としての青銅(10%Al,90%C

(2)の表面の微細構造は、第2図に示すようになる。This material is bronze (10% Al, 90% C) as a thermal spray material.
u) is sprayed onto the outer peripheral wall of the plug body (2) so that the thickness of the sprayed coating is about 0.6 mm, and then the sprayed coating is about 0.2 m thick.
After cutting / polishing to about m, the polished surface is superolled (the surface of the metal is crushed by a roller for smooth precision finishing) to form a predetermined metal spray layer (K). There is. Then, the fine structure of the surface of the metal sprayed plug (2) is as shown in FIG.

金属溶射で形成された小さな多数の空洞(12)(12)が
形成されることとなる。そして、栓体(2)の外周面に
形成された上記金属溶射層(K)にグリス(13)を塗布

(K)の表面に残存・露出する余剰グリス(14)以外に
も、金属溶射層(K)の内部に浸透した浸透グリス(1
5)が存在するから、前記余剰グリス(14)が栓体
(2)と栓体収容室(10)間から流出しても浸透グリス
(15)によってガスコック本体(1)と栓体(2)との
摩擦力は極端に増加しないものとなる。That is, the metal sprayed layer (K) is formed on the outer peripheral surface of the plug body (2), and a large number of small cavities (12) formed by metal spraying are formed in the metal sprayed layer (K). (12) will be formed. Then, when grease (13) is applied to the metal sprayed layer (K) formed on the outer peripheral surface of the plug body (2), the grease forms a cavity (1) in the metal sprayed layer (K).
2) While penetrating into the portion (12) and being retained in the portion, other surplus grease (14) remains on the surface. That is, on the surface of the plug body (2), in addition to the surplus grease (14) remaining / exposed on the surface of the metal sprayed layer (K), the permeated grease (1) that has penetrated into the metal sprayed layer (K).
Due to the presence of 5), even if the excess grease (14) flows out between the plug body (2) and the plug body storage chamber (10), the permeation grease (15) allows the gas cock body (1) and the plug body (2). The frictional force between and will not increase extremely.
従って、栓体(2)を繰返えして回動させてもグリス
不足を起こす心配は少なくなる。Therefore, even if the stopper (2) is repeatedly rotated, the risk of running out of grease is reduced.
次に、上記栓体(2)を具備する五個のガスコックに
ついて行なった耐久試験結果を第1表に示す。Next, Table 1 shows the results of the durability test conducted on the five gas cocks having the plug (2).
上記耐久試験は、ガスコックの開閉を一分間に十回の
割合で繰返えして行ない、所定の回数回動させた後にお
ける栓体(2)の回動必要トルクを測定したものであ
る。In the above durability test, the opening and closing of the gas cock was repeated at a rate of 10 times per minute, and the rotation required torque of the plug body (2) was measured after rotating the gas cock a predetermined number of times.
上記第1表からも解るように、操作回数の増加に伴な
って、所要トルクは全ての試料について増加しているも
のの、最も悪い結果のものでも、操作回数が10000回の
時点で、試験開始直後の所要トルクの2倍程度であっ
た。 As can be seen from Table 1 above, the required torque increased for all samples as the number of operations increased, but even with the worst result, the test started at the time of 10,000 operations. It was about twice the required torque immediately after.
尚、金属溶射層(K)を形成したもの(以下、溶射品

コック本体(1)と栓体(2)相互のカジリ付きの対策
として有効であることがわかる。It should be noted that it is not the one having the metal sprayed layer (K) formed (hereinafter, referred to as a sprayed product), but a normal gas cock (hereinafter, referred to as a gas cock body (1) and a plug body (2) made of different metals. In the case of (the conventional product), the torque required to rotate the stopper is about 10 kgcm in the initial state and 20 in 2000 times.
It becomes about 50 kgcm at -25 kgcm, 5000 times, which is much larger than the required torque when the gas cock of the embodiment of the present invention is opened and closed the same number of times. That is, from Table 1, in the case of the above-mentioned embodiment in which the metal sprayed layer (K) was formed, the gas cock body (1) and the plug body (2) were It can be seen that it is effective as a measure against galling.
次に、上記実施例のガスコックは、既述したように、
ガスコック本体(1)と栓体(2)とを同種金属で構成

設置されても、第2表に示すように、栓体(2)、の円
滑な開閉操作が約束される。Next, the gas cock of the above embodiment, as described above,
Since the gas cock body (1) and the plug body (2) are made of the same metal, the plug body (2) and the gas cock body (1) have the same expansion even when the gas cock is installed in a relatively high temperature place. As a result, the plug body (2) is promised to be smoothly opened and closed even if the plug body (2) is installed in a place where the temperature condition is bad, as shown in Table 2.

2表に示す。The heat resistance test shown in Table 2 was performed by holding the gas cock at 60 ° C. for 2 hours and then at 10 ° C. for 2 hours, repeating one cycle 10 times. The plug (2) before the test
It is a comparison of the torque required for the rotation of and the required torque for opening and closing after the test. The samples to be compared are the above-mentioned thermal spray product and the conventional product. The test results are shown in Table 2.
第2表から溶射品のものにおける上記所要トルクは、
試験前と試験後とを比較すると1.5〜2倍程度であるの
に対し、従来品のものでは2〜2.5倍程度であること、
又、始動時では約50倍程度であることがわかる。 From Table 2, the above required torque for sprayed products is
Comparison between before and after the test is about 1.5 to 2 times, whereas that of the conventional product is about 2 to 2.5 times,
Also, it can be seen that it is about 50 times at the start.
即ち、従来品は熱膨張率の違いから熱の影響をうけて
所要トルクが大きくなり、他方、ガスコック本体(1)
と栓体(2)とを同種金属で構成させた溶射品は、溶射
層を別金属によって形成させているにもかかわらず、熱
の影響を受けないことがわかる。That is, in the conventional product, the required torque increases due to the influence of heat due to the difference in the coefficient of thermal expansion, while the gas cock body (1)
It can be seen that the thermal sprayed product in which the plug and the plug (2) are made of the same metal is not affected by heat even though the sprayed layer is made of another metal.
又、第2表から、試験前における栓体(2)の回動に
必要なトルクは、溶射品のものは従来品のもと比較する
と、半分程度であることが判明した。Further, from Table 2, it was found that the torque required to rotate the plug (2) before the test was about half of that of the sprayed product compared with the conventional product.
上記した二つの試験から、ガスコック本体(1)と栓
体(2)とを同種の金属で構成し、これら相互間に青銅
の金属溶射層(K)を形成した場合には、既述した主要
効果に加えて、雰囲気温度が高くなる環境下においても
カジリ付きが発生しにくいものとなる。From the above two tests, when the gas cock body (1) and the plug body (2) were made of the same kind of metal and the metal sprayed layer (K) of bronze was formed between them, In addition to the effect, galling is less likely to occur even in an environment where the ambient temperature is high.
又、他の方法による摺動面の表面処理(メッキ,拡散
処理)等に比べて膜厚を厚く(従来の摺動面の表面処理
層:数μm〜数十μm,容赦による金属処理層:数百μ
m)することが容易であり、この為、グリスの浸透保持
量を多くすることができる。In addition, the film thickness is thicker than the surface treatment (plating, diffusion treatment) of the sliding surface by other methods (conventional surface treatment layer of sliding surface: several μm to several tens of μm, metal treatment layer due to pardon: Hundreds of μ
m) is easy, and therefore the amount of grease permeated and retained can be increased.
更に、他の方法に比べ処理時間を短縮することができ
る。Furthermore, the processing time can be shortened compared to other methods.
尚、この実施例のものは、栓体(2)の外周面側に金

Further, although the gas cock body (1) and the plug body (2) are made of the same kind of metal, the gas cock body (1) and the plug body (2) are used in an environment where the temperature does not rise.
And may be made of different metals.
