Batch arrangements of butterfly valves

도면은 본 고안의 실시예를 나타낸 것이며The drawing shows an embodiment of the present invention

제1도는 시이트링 단면도.1 is a cross-sectional view of the seat ring.

제2도는 변접부의 종단면도.2 is a longitudinal sectional view of the contact portion.

근래에 와서 나비형밸브(butterfly valve)의 사용범위가 크게 확장되고, 하물유(荷物油)의 종류도 매우 다양해졌고 적용온도도 종전의 70℃ 를 넘어 통상 100℃에서 사용하게 되었고, 유속(流速)도 증가하여 종전의 합성고무 시이트를 끼우는 것만으로는 온도 및 기름의 종류에 따라서는 팽장해서 새어나오는 등 사고의 원인이 되고 있는 실정이다.In recent years, the use range of butterfly valves has been greatly expanded, the types of cargo oil have become very diverse, and the application temperature has been used at 100 ℃, in general, above 70 ℃. ), And the conventional rubber sheet is only inserted to cause an accident, such as expansion and leakage depending on the temperature and the type of oil.

본 고안은 이와 같은 결점을 완전히 제거하려는 것으로써, 볼록형(凸形) 철심(鐵芯)에다 파형(波形)합성고무를 단단히 열융착해서 일체로 만들고, 양쪽에는 반경이 작은 O형 돌출부를 만들고, 밸브에다 철편을 덧대서 무리하게 조여 부치지 않고서도 완전히 밀봉할 수가 있으며 대량 생산에도 적합한 변폭용(變幅用)시이트를 제공하려는 것이다.The present invention intends to completely eliminate such defects, by consolidating the convex iron core and the corrugated rubber firmly by heat fusion, and making the O-shaped protrusions with small radius on both sides. The purpose of this article is to provide a transformer sheet that can be completely sealed without forcibly tightening by attaching iron pieces to the valve and suitable for mass production.

본 고안의 실시상태를 도면의 실시예에 따라 설명하면, 밸브하우징시이트(1)의 환상내접면을 밸브본체(2)와, 이것에 고정 설치된 밸브봉(變棒)(3)의 중심으로 부터 반경 궤적의 접선방향의 테이퍼 시이트 면(4)으로 형성하고, 표면에는 두꺼운 경질 크롬도금을 하여 내구성을 갖도록 하고, 밸브본체(2)는 밸브봉(3)과 테이퍼핀을 사이에 두고 고착되고, 밸브봉(3)의 회전으로 밸브 하우징시이트(1)에 변접(變接) 개폐되는 것이며, 밸브본체(2)의 외주에는 조이는데 사용되는 환상의 지지판(5)의 홈공(溝孔)(6)과 마주보는 홈공(6')을 층이지게 만든 요함부(7)를 만들고 이것에 단면이 십자모양으로된 철심(8)의 상면에 밸브하우징시이트(1)면에, 중간에 위로 벌어진 八자모양의 빈곳(空所)(9)에 의하여, 크고 작은 단면이 반원형인, 파상(波狀) 팽출부(10)(11)가 있는 합성고무환(12)을 열융착가류(加硫)해서 밀착시키고, 다시 그 양측면에 단면이 반원형인 팽출부(13)(14)를 배설한 시이트링(15)을 감장하고, 환상의 지지판(5)의 홈공(6)을 거쳐서 합착 내장하고, 환상의 지지판(5)에 배설한 스프링와셔(6)와 조이는 볼트(17)로 조여부쳐서 된것이다.Referring to the embodiment of the present invention according to the embodiment of the drawings, the annular inner surface of the valve housing sheet 1 from the center of the valve body 2 and the valve rod (3) fixed to it The tapered sheet surface 4 in the tangential direction of the radial trajectory is formed, and the surface is coated with thick hard chromium plating for durability, and the valve body 2 is fixed with the valve rod 3 and the tapered pin interposed therebetween. The grooves of the annular support plate 5 used to tighten the valve housing sheet 1 by opening and closing the valve housing sheet 1 by rotation of the valve rod 3. 8) is formed in the recess (7) to form a groove (6 ') layered facing the hole (6') and on the valve housing sheet (1) surface on the upper surface of the cross-shaped iron core (8) Sum with wave-like bulges 10 and 11, in which the large and small cross-sections are semicircular, by means of magnetic voids 9; The rubber ring 12 is brought into close contact with each other by heat fusion vulcanization, and the sheet ring 15 having the semicircular swelling portions 13 and 14 having a semicircular cross section is mounted on both sides thereof, and the annular support plate 5 The spring washer 6 and the fastener which are built-in via the groove hole 6 of () and installed in the annular support plate 5 are tightened with the bolt 17.

본 고안은 상술한 실시예와 같이 형성되어 있으므로 테이퍼 상밸브 하우징 시이트(1)면에 십자상철심(8)에 열융착하여 고정 설치된 변접용 사이트링(15)의 크고 작은 파상 팽출부(10)(11)는, 중간의 위로 향한 八자상의 빈곳(9)에 의해서, 그 변형된것을 흡인(吸引)할 수가 있어서, 완전히 밸브 하우징시이트(1)면에 밀착 변접하는 동시에 안으로부터의 압력에 대해서 대형팽출부(10)가 누설된 경우에도 빈곳(9)에 머물어서 그 변형을 복원시키는 힘이 되고 소형팽출부(11)는 시이트(1)면으로 가입되어서 밀착하게 되어 완전 밀봉하는데 도움이 되고, 또한 외부로 부터의 압력에 대해서도 똑같이 밀봉효과를 발휘하는 효과적인 나비형밸브의 변접장치를 제공하는 것이다.Since the present invention is formed as in the above-described embodiment, the large and small wave-shaped swelling portions 10 of the contacting side ring 15 installed by heat-sealing and fixed to the cross-shaped iron core 8 on the tapered upper valve housing sheet 1 surface are fixed. (11) is capable of sucking the deformed portion by the intermediate upward vacant space (9), so as to be completely in close contact with the valve housing sheet (1) surface and against pressure from the inside. Even when the large swelled portion 10 is leaked, it is a force for restoring the deformation by staying in the vacant place 9, and the small swelled portion 11 is joined to the sheet 1 surface to be in close contact, which helps to seal it completely. In addition, the present invention provides an effective butterfly valve contacting device that exhibits the same sealing effect against external pressure.
