본 고안은 주로 진공펌프와 인입파이프 사이에 설치하여 사용하는 체크밸브에 관한 것으로, 특히 밸브 케이싱을 상하 밸브 케이싱으로 구분 형성하고 이 상하 케이싱의 사이에 밸브 시이트 및 밸브판을 설치하므로써 제작 조립이 간편하도록 한 것이다.The present invention mainly relates to a check valve installed between a vacuum pump and an inlet pipe. Particularly, the valve casing is divided into upper and lower valve casings, and a valve sheet and a valve plate are installed between the upper and lower casings, thereby simplifying fabrication and assembly. I did it.

종래의 체크밸브를 보면 대부분 밸브 케이싱을 단일체로 구성하고 밸브시이트는 되도록이면 밸브케이싱과 일체로 구성하려는 관념때문에 오히려 금형제작이 까다롭게 되고 정밀도가 떨어지며 조립이 용이하지 않았던 결점이 있었다.In the conventional check valve, most of the valve casing is composed of a single body, and the valve seat has a drawback that the mold making is difficult, the precision is low, and the assembly is not easy due to the idea of constructing the valve casing integrally with the valve casing.

본 고안은 종래의 이러한 결점을 감안하여 밸브케이싱을 상하로 대칭되게 분리구성하고 이들 상하 케이싱 사이에 밸브시이트판을 끼워 설치하며 밸브시이트판의 중앙에는 밸브판을 스프링으로 탄압 설치하는 간단한 구조로 구성하여, 제작 및 조립작업이 간편하고 정밀도가 높으며 동작이 확실한 체크밸브를 제공하기 위한 목적으로 안출한 것이다.The present invention is constructed in a simple structure in which the valve casing is symmetrically separated from the upper and lower casings, and the valve seat plate is inserted between the upper and lower casings, and the valve plate is pressed down by the spring in the center of the valve seat plate. In order to provide a check valve that is easy to manufacture and assemble and has high precision and reliable operation.

이하 도면에 따라 그 구성을 상세히 설명한다.Hereinafter, the configuration will be described in detail with reference to the accompanying drawings.

1과 1'는 서로 동일형상으로 대칭되게 조립되는 상.하 밸브케이싱으로, 상하주연에 플랜지(2) (2')와 돌출편(3) (3')을 형성하고 서로 접하는 대접부에 패킹(5) (5')이 각기 설치된 받침턱(4) (4')을 형성하며 각 중공부(6) (6')의 상. 하부에 유입공(7)과 유출공(7')을 형성한다.1 and 1 'are upper and lower valve casings which are assembled symmetrically in the same shape, forming flanges (2) (2') and protrusions (3) (3 ') on the upper and lower periphery and packing them in contact with each other. (5) The image of each hollow part 6, 6 'which (5') forms the supporting jaw 4, 4 'which is installed, respectively. The inlet hole 7 and the outlet hole 7 'is formed in the lower portion.

8은 밸브시이트판으로 외주연에 플랜지(9)가 형성되고 중앙에 축공(10)과 유통공(11)이 뚫려 있으며 하부에는 요입부(12)로 이루어지는 밸브시이트(13)를 형성한다.8 is a valve sheet plate, the flange 9 is formed on the outer periphery, the shaft hole 10 and the distribution hole 11 is drilled in the center and the lower portion forms a valve sheet 13 consisting of the recessed portion (12).

14는 반구형의 고무재 밸브판으로 내부에 보강심재(15)를 내입하고 정상에는 나사공(16)을 형성하여, 이에 상단에 걸림턱(18)을 형성하고 하단에 나사부(19)를 형성한 밸브봉(17)을 스프링(20)이 끼워진 상태에서 결합한다.14 is a hemispherical rubber valve plate with a reinforcing core material 15 inserted therein, and a screw hole 16 is formed at the top thereof, thereby forming a locking jaw 18 at the top and a threaded portion 19 at the bottom. The valve rod 17 is coupled to the spring 20 in the fitted state.

미설명부호 21은 볼트, 22는 너트, 23은 워셔이다.Reference numeral 21 is a bolt, 22 is a nut, 23 is a washer.

이와같이 구성된 본 고안은 밸브시이트판(8)의 중앙 축공(10)에 스프링(20)과 워셔(23)를 끼운 밸브봉(17)을 관통시켜 그 관통된 하단에 밸브판(14)을 나사결합한 다음 밸브판(14)이 결합된 밸브시이트판(8)을 하부 밸브케이싱(1')의 받침턱(4')상부에 얹어놓고 그 위에 상부 밸브케이싱(1)을 얹어 서로 대면하는 상하케이싱의 돌출턱(3) (3')끼리 볼트(21)와 너트(22)로 체결하여서 조립하는 것으로 그작용, 효과는 다음과 같다.The present invention constituted as described above allows the valve shaft 14 through which the spring 20 and the washer 23 are fitted to the central shaft hole 10 of the valve seat plate 8 to screw the valve plate 14 at the lower end thereof. Next, the valve sheet plate 8 to which the valve plate 14 is coupled is placed on the upper side of the base 4 'of the lower valve casing 1', and the upper valve casing 1 is placed thereon to face each other. The protrusions 3 and 3 'are assembled by fastening the bolts 21 and the nuts 22 to each other so that their effects and effects are as follows.

즉, 본 고안이 설치된 진공펌프등이 동작하여 공기를 흡입하면 공기등의 유체가 유입공(7)으로 들어와 제2도와 같이 밸브시이트판(8)의 유통공(11)을 통과하는데 이때 밸브판(14)은 유체의 압력에 의해 밀려나므로 일방향 통과는 자유로우나 진공펌프의 동작이 중지될 경우에는 스프링(20)의 탄발력에 의해 제3도와 같이 밸브판(14)이 밸브시이트(8)를 막아 밀폐시켜 주어 유체의 역류를 방지하는 것이다.That is, when the vacuum pump or the like installed with the present invention operates to suck in air, fluid such as air enters the inflow hole 7 and passes through the distribution hole 11 of the valve seat plate 8 as shown in FIG. 14 is pushed by the pressure of the fluid, so one-way passage is free, but when the operation of the vacuum pump is stopped, the valve plate 14 moves the valve seat 8 as shown in FIG. 3 by the elastic force of the spring 20. It prevents backflow of fluid by blocking and sealing.

이러한 본 고안은 상, 하밸브케이싱(1) (1')들 동일형상으로 구성하였기 때문에 금형제작에 있어 하나의 금형만 제작하면 되므로 제작비를 절감할 수 있고 상하 밸브케이싱(1) (1')의 대접부에 밸브시이트판(8)을 끼워 설치하므로 밸브의 조립작업이 용이하며 밸브시이트판(8)의 밸브케이싱과 별도로 구성되어 있으므로 밸브시이트의 정밀가공이 가능하여 밸브판(14)과의 사이에 밀폐효과가 완벽하며, 보강심재(15)에 의해 밸브판(14)의 변형이 방지되고 수명도 향상되는 것등의 특징을 지닌 것이다.Since the present invention consists of the upper and lower valve casings (1) and (1 ') in the same shape, only one mold needs to be manufactured in the mold manufacturing, and thus the manufacturing cost can be reduced, and the upper and lower valve casings (1) and (1') The valve seat plate 8 is fitted to the welded portion of the valve to facilitate the assembly of the valve, and since it is configured separately from the valve casing of the valve seat plate 8, the valve sheet can be precisely processed so that the valve sheet 14 can be The sealing effect is perfect, and the deformation of the valve plate 14 is prevented by the reinforcing core material 15, and the service life is also improved.
