Abstract

PURPOSE: An injector is provided to use not only at a low water pressure with strong suction power but also for a pipe flowing little water. CONSTITUTION: An injector has a rectangular sill on the rear part of a narrow portion. An intake hole is formed in the back of the sill. Thereby, suction is performed. The injector is used at the low water pressure under 0.5kgf/cm¬2 as a compact injector. The injector is used in a place to need the strong suction power and having various water pressure. The suction of the injector is maintained in a situation that the suction of an existing injector is impossible.

Description

낮은 수압에서도 흡인력이 강한 인젝터.Strong injector even at low water pressure.

도 1과 같이 관을 좁혔다가 다시 넓히게 될 때에 좁아지는 부분에서는 흐름이 방해를 받아 압력이 높아지고 그 압력으로 인해 좁아진 부분에서는 유속이 빨라지며 다시 넓어 지므로 그 유속에 방해가 없어 압력이 걸리지 않으므로 좁아진 부분중 뒷 부분은 압력이 매우 낮아지게 된다. 도 2와 같이 ↓표의 위치에 흡입구를 두면 관 밖의 기체 또는 액체를 흡입하게 되는데 이렇게 만든 도구를 통상 인젝터 또는 벤츄리 인젝터 라고 한다.When the tube is narrowed and then widened again as shown in FIG. 1, the narrowed portion is interrupted by the flow, and the pressure is increased. At the back, the pressure is very low. As shown in Figure 2 when the suction port is placed in the position of the ↓ table to inhale the gas or liquid outside the tube. The tool made in this way is called an injector or venturi injector.

낮은 수압에서 기존 인젝터는 흡인력을 상실하게 되는데 본 발명은 낮은 수압에서도 강한 흡인력으로 흡입할 수 있게 한 것이다. 인젝터의 압력의 차이만 가지고 흡입이 이루어지지 않는 상황에서 다음과 같은 과학적 원리를 추가 적용하여 흡인력이 강한 새로운 인젝터를 만들 수 있게 한 것이다. 물이 관을 따라 일정한 속도와 압력으로 흐를 때 그 흐르는 물의 유속의 관성을 방해할 때 생기는 효과를 적용하여 흡인력을 극대화 시킨 것이 본 발명의 특징이다. 도 2와 같이 좁아지는 부분에 도 2의 3과 같은 직각에 가까운 작은 턱을 만들어 유속의 관성을 방해 하면 턱에 부딪히는 물이 관의 중심쪽으로 튀어 밀리며 외부쪽의 물의 흐름을 방해하게 된다. 이 관계로 턱의 바로 뒤에 근접한 부분의 압력이 매우 낮아지게 되는데 이곳에 흡입구를 두면 흡입력이 매우 강하게 되고 낮은 수압에서도 흡입이 이루어진다.At low water pressure, the existing injector loses the suction force, and the present invention makes it possible to suck with a strong suction force even at low water pressure. In the situation where suction is not made only by the difference of the pressure of the injector, the following scientific principle can be additionally applied to make a new injector with strong suction force. It is a feature of the present invention to maximize the attraction force by applying the effect that occurs when water flows at a constant speed and pressure along the pipe and interferes with the inertia of the flow rate of the flowing water. If a small jaw close to the right angle as shown in 3 of FIG. 2 is made in the narrowed portion as shown in FIG. Because of this, the pressure in the immediate area behind the chin becomes very low. If the suction port is placed here, the suction power becomes very strong and suction is performed even at low water pressure.

도 1은 기존 인젝터의 단면도.1 is a cross-sectional view of an existing injector.

도 2는 본 발명 인젝터의 단면도.2 is a cross-sectional view of the injector of the present invention.

본 발명의 인젝터는 도 2와 같은 구조로서 관이 좁아지는 부분 후단에 그림 2의 3과 같이 직각에 가까운 턱을 만들고 그 턱 바로 뒷부분에 흡입구를 두어 흡입이 이루어 지게 한 것이다.The injector of the present invention has a structure as shown in FIG. 2 to make a jaw close to a right angle as shown in FIG.

이 인젝터는 0.5kgf/㎠이하의 낮은 수압에서도 사용할 수 있다. 매우 소형의 소요량 인젝터로도 사용이 용이 하다. 강한 흡인력을 얻을 수 있어 강한 흡인력이 필요한 곳에 용이하게 사용할 수 있다. 수압이 변하는 곳에서도 안전하게 사용할 수 있다. 인젝터 뒷부분에서 어느 정도의 압력이 걸려 기존 인젝터 에서는 흡입이 이루어 지지 않을 상황에서도 흡입이 지속되어 이런 경우에도 이용할 수 있다.The injector can be used at low water pressures below 0.5 kgf / cm 2. Easy to use even with very small requirement injectors. A strong suction force can be obtained and can be easily used where a strong suction force is required. It can be used safely even where the pressure changes. Some pressure is applied at the back of the injector, so that the suction continues even in the case where the suction is not performed in the conventional injector and can be used even in this case.
