[발명의 배경][Background of invention]

본 발명은 전자기적으로 작동가능한 이중 시이트 밸브(seat valve)에 관한 것이다. 이러한 밸브에 있어서, 압력매체 통로는 밸브 시이트판과 밸브 부재를 작동시키는 전기자의 태핏(tappet) 사이에 형성되어 있다. 이러한 구조는 언제나 양호하지는 않다(미국 특허 제 4 556 085 호).The present invention relates to an electromagnetically actuated double seat valve. In such valves, a pressure medium passage is formed between the valve seat plate and a tappet of the armature for actuating the valve member. This structure is not always good (US Pat. No. 4,556,085).

[발명의 장점]Advantages of the Invention

이에 반하여, 청구범위의 특징절에 기재된 본 발명에 따른 이중 시이트 밸브는 매우 간단한 구조로 구성되고, 비교적 적은 부품만이 요구되는 등의 장점을 갖는다. 예비 조립된 부품이 사출성형 몰드에 놓여진 다음 플래스틱이 상기 부품 주변에 사출되기 때문에, 생산비가 적어지게 된다.In contrast, the double seat valve according to the invention described in the characterizing section of the claims has the advantage of being of a very simple construction, requiring only relatively few parts and the like. Since the pre-assembled part is placed in the injection molding mold and the plastic is injected around the part, the production cost is reduced.

[도면][drawing]

본 발명의 양호한 실시예는 도면 및 하기 설명으로 보다 상세히 설명된다. 도면은 전자기적으로 작동가능한 이중 시이트 밸브의 길이 방향 단면도이다.Preferred embodiments of the invention are explained in more detail by the figures and the following description. The figure is a longitudinal cross section of an electromagnetically actuated double sheet valve.

[양호한 실시예의 설명]DESCRIPTION OF THE PREFERRED EMBODIMENTS

상기 전자기 밸브는 구형 밸브 부재(13)를 미끄럼 이동가능하게 안내하는 환형의 접시머리 모양(counter-sunk) 개구를 그 베이스(11)에 갖고 있는 시이트 스틸의 포트형 하우징 본체(10; a pot-shaped housing body)를 갖는다. 이는 2개의 밸브 시이트(14,15)와 협동한다. 하우징 본체(10)내에는 전자석의 랩핑 소자(16; wrapping element)가 놓여 있으며, 밸브 부재(13)는 전기자를 형성한다. 하우징 본체의 베이스에는, 개구(12)에 부가하여, 압력매체 흐름 통로로서 작용하는 양극성의 천공구(17)가 제공되어 있다. 하우징의 중앙부에는, 밸브 시이트(15)에서 끝나는 통로(20)를 가진 플래스틱 슬리브(19)가 제공된 원통형 대향 폴(18)이 위치되어 있다. 슬리브의 하나의 견부(20A)에는 밸브 부재(13)를 밸브 시이트(14)에 가압시키는 압력 스프링(21)이 고정되어 있다. 상술된 부품들 즉, 하우징 본체(10), 대향 폴(18) 및 전기 연결부는 예비 장착되어, 밸브 하우징이 플래스틱 사출성형에 의해 최종 형태로 수용되는 사출 몰드에 위치된다. 이러한 방법에 의해 제조가 매우 용이해진다.The electromagnetic valve is a pot-shaped housing body 10 of sheet steel having an annular counter-sunk opening in its base 11 which slidably guides the spherical valve member 13. a shaped housing body. It cooperates with two valve seats 14 and 15. In the housing body 10 a wrapping element 16 of the electromagnet is placed, and the valve member 13 forms an armature. In the base of the housing body, in addition to the opening 12, a bipolar drilling tool 17 acting as a pressure medium flow passage is provided. At the center of the housing is located a cylindrical opposing pawl 18 provided with a plastic sleeve 19 with a passage 20 ending in the valve seat 15. A pressure spring 21 that presses the valve member 13 to the valve seat 14 is fixed to one shoulder 20A of the sleeve. The above-mentioned parts, namely the housing body 10, the opposing poles 18 and the electrical connection, are pre-mounted so that the valve housing is placed in an injection mold which is received in its final form by plastic injection molding. In this way, manufacturing becomes very easy.

원통형 연장부(23)는 밸브 하우징의 하부에 형성되어 있고, 그 연장부에는 플래스틱으로 이루어진 연결부(24)가 삽입되어, 밸브 하우징에 초음파 용접되어 있다. 물론, 압력 스프링(21) 및 밸브 부재(13)는 이전에 삽입된다. 플래스틱의 밸브 부재(13)의 설계로 인해, 잉여의 공기 갭이 자동적으로 형성된다.The cylindrical extension part 23 is formed in the lower part of the valve housing, The connection part 24 which consists of plastics is inserted in the extension part, and is ultrasonically welded to the valve housing. Of course, the pressure spring 21 and the valve member 13 are previously inserted. Due to the design of the valve member 13 of the plastic, an excess air gap is automatically formed.

연결부(24)에는, 블라인드 드릴 구멍(25; blind drill hole)이 제공되어 있고, 그 상부 모서리는 밸브 사이트(14)를 형성하며, 횡방향 블라인드 드릴 구멍(26)이 그 아래로 이어져 있고, 압력 매개원이 연결되어 있다. 두 개의 연속 블라인드 드릴 구멍(27,28)은 상기 구멍에 평행하게 연결부(24)에 위치되고, 상기 드릴 구멍은 컨슘머(consumer)와 연결되어 있다. 신속한 스위칭(switching)을 위해서, 상기 밸브 부재(13)는 밸브 시이트(14,15)사이에서 이동하도록 비교적 작은 간격을 갖는다. 플래스틱으로 구성되었기 때문에, 양호한 감쇠성 및 소음 감소를 얻게 된다. 대향 폴(18)의 통로(20)는 압력 매체 컨테이너에 연결되어 있다.The connection portion 24 is provided with a blind drill hole 25, the upper edge of which forms a valve site 14, with a transverse blind drill hole 26 running down therein, pressure The mediator is connected. Two continuous blind drill holes 27, 28 are located in the connection part 24 parallel to the holes, which are connected to a consumer. For fast switching, the valve member 13 has a relatively small gap to move between the valve seats 14 and 15. Since it is made of plastic, good damping and noise reduction are obtained. The passage 20 of the opposing pawl 18 is connected to the pressure medium container.

랩핑 소자(16)의 비여자(non-excited) 상태에서, 밸브 부재(13)는 압력 스프링(21)의 스프링력으로 인해 밸브 시이트(14)상에 놓여 있게 된다. 압력 매체는 컨슘머로부터 연결부(24)의 드릴 구멍(26,27)과 하우징 본체(10)의 천공구(17)를 거쳐 개방 밸브 시이트(15)로 통과될 수 있고, 통로(20)를 지나 컨테이너로 흐른다. 랩핑 소자(16)가 여자될 경우, 펌프에 의해 상기 드릴 구멍(26)을 거쳐 드릴 구멍(25)으로 전달된 압력매체가 직접 블라인드 드릴 구멍(26,27)안으로 통과되고 이들로부터 컨슘머로 전달될 수 있도록, 상기 밸브 부재는 밸브 시이트(15)상에 위치된다. 밸브 부재(13)의 밸브 이동이 매우 작기 때문에 신속한 연속적인 스위칭 작동이 가능해진다.In the non-excited state of the wrapping element 16, the valve member 13 is placed on the valve seat 14 due to the spring force of the pressure spring 21. The pressure medium can pass from the calculator to the open valve seat 15 via the drill holes 26, 27 of the connection 24 and the drilling tool 17 of the housing body 10, passing through the passage 20. Flow into the container. When the lapping element 16 is excited, the pressure medium delivered by the pump to the drill hole 25 via the drill hole 26 is passed directly into the blind drill holes 26 and 27 and from there to be delivered to the comsumer. So that the valve member is located on the valve seat 15. Since the valve movement of the valve member 13 is very small, a rapid continuous switching operation is possible.
