본 고안은 펌프의 보충액 주입컵에 관한 것으로, 특히 펌프하우징의 보충액주입로에 직접 나사맞춤으로 체결되는 주입컵 몸체에 보충액의 유입을 개폐하는 개폐밸브를 일연체로 구비하고, 내부에 보충액고임부를 형성하여, 제품자체의 구성이 간단하고 펌프와의 조립이 용이하게 되도록한 펌프의 보충액 주입컵에 관한 것이다.The present invention relates to a replenishment liquid injection cup of a pump, and in particular, an injection cup body which is fastened by screwing directly into a replenishment liquid injection passage of a pump housing is provided with an opening / closing valve for opening and closing the inflow of replenishing liquid as a single body, Forming, and relates to a replenishment liquid injection cup of the pump so that the configuration of the product itself is simple and easy assembly with the pump.

일반적인 양수기와 같은 급수용펌프와 유류 또는 황산등을 사용하는 공업용 펌프등 각종 펌프는 최초 구동시에 외부로 부터 보충액을 주입한 후 구동하고 있는 바, 종래의 펌프는 펌프의 하우징 일측부에 형성된 보충액유입관에 별도의 개폐밸브를 개재하고 깔대기형 보충액 주입컵을 연결하여 보충액 주입컵으로 보충액을 주입하는 구조로 되어 있다.Various pumps such as water pumps such as general water pumps and industrial pumps using oil or sulfuric acid are driven after injecting supplemental liquid from the outside during initial operation. The conventional pump is supplemented with liquid inlet formed at one side of the housing of the pump. A separate opening and closing valve is connected to the pipe to connect the funnel-type supplement liquid infusion cup to inject the supplement liquid into the supplement liquid infusion cup.

이러한 종래의 보충액 주입용 주입컵은 보충액을 주입하고자 하는 경우에 개폐밸브를 개방하고, 주입후에는 펌프가동에 따르는 펌프의 내압 상승에 의하여 보충액이 외부로 비산하게 되므로 개폐밸브를 다시 폐쇄하여야 한다.Such a conventional injection cup for replenishment liquid injection opens and closes the valve when the replenishment liquid is to be injected, and after the injection, the replenishment liquid is scattered to the outside due to the increase in the internal pressure of the pump according to the pump operation.

상기와 같이 종래에는 별도의 개폐밸브를 필요로 하므로 원가상승의 요인이 되고 가동할때마다 개폐밸브를 조작하여야 하므로 사용이 번거로울뿐아니라, 펌프하우징에 개폐밸브와 보충액 주입컵을 니플을 사용하여 연결하므로 조립이 번거로운 결함 등이 있었다.As described above, since a separate on-off valve is required, it is a factor of cost increase and the on-off valve must be operated every time it is operated, and it is cumbersome to use, and the on-off valve and the replenishment liquid injection cup are connected to the pump housing by using a nipple. Therefore, there were troublesome defects such as assembly.

또한 보충액 주입컵에 개폐밸브가 자체적으로 구비하도록 보충액 주입컵을 2부분으로 분할하여 두 분할체를 나사식으로 조립하도록 한 합성수지제 보충액 주입컵이 알려지고 있는 바, 이러한 보충액 주입컵은 컵형상의 상부몸체와 깔대기 형상의 하부몸체로 분리형성되고, 하부몸체의 내주면에 상부몸체의 외주면을 나사맞춤으로 결합하도록 되어 잇으며, 상부몸체의 저면에는 다수개의 보충액 유통공이 형성됨과 아울러 저면의 하측 중앙부에는 깔대기형 하부몸체의 배출구를 폐쇄하게 되는 폐쇄돌기가 형성되고 그 하부몸체의 배출구 내주면에는 연결용 니플을 체결하기 위한 나사부가 형성된 구조로서, 사출성형하기가 매우 복잡할 뿐아니라 하부몸체는 사출성형한 후 나사부를 별도의 공정으로 가공하여야 하므로 생산성이 저하되는 결함이 있었고, 공업용 펌프로 예를들어 황산이나 유류등을 펌핑하는 경우에는 보충액 공급후 작동시에 상부몸체를 손으로 잡고 돌려 하부몸체와 긴밀히 조임으로써 폐쇄하게 되는 바, 이때 보충액이 손에 묻게되어 사용이 번거롭게 되는 것이었으며, 연결부에 별도의 철재니플을 사용하여 내산성이 약하고 쉽게 부식되는 결함등이 있었다.In addition, it is known that a synthetic resin supplement liquid infusion cup is formed by dividing the supplement liquid infusion cup into two parts so that the opening and closing valve is provided in the supplement liquid injection cup by itself, and this supplement liquid infusion cup has a cup shape. The upper body and the funnel-shaped lower body is formed separately, and the outer peripheral surface of the upper body is coupled to the inner circumferential surface of the lower body by screwing, the bottom surface of the upper body is formed with a plurality of replenishment fluid distribution holes and at the lower center of the lower surface A closing protrusion is formed to close the outlet of the funnel-type lower body, and a screw part is formed on the inner circumferential surface of the lower body of the lower body to form a connection nipple. The injection molding is not only complicated, but also the lower body is injection molded. After the thread is processed in a separate process, there is a defect that the productivity is reduced. In the case of pumping sulfuric acid or oil with industrial pumps, for example, when the supplementary fluid is supplied, the upper body is held tightly by hand and then tightened tightly with the lower body to operate the supplementary liquid. It was cumbersome, and there was a defect that the acid resistance was weak and easily corroded by using a separate steel nipple on the connection part.

본 고안은 상기한 바와같은 종래의 결함을 해소하기 위하여 안출한 것으로 깔대기형 주입컵 몸체를 그 하단부에 형성된 체결관으로 펌프하우징의 보충액주입로 상단부에 나사맞춤으로 직접 체결하고 주입컵 몸체의 내측에는 환상 돌출턱을 형성하여 그 주위에 보충액고임부를 형성하며, 그 상측부에는 보충액의 유입을 개방 또는 차단하는 가동개폐구를 재치시키고, 유통공을 가지는 지지구를 네크부 상측에 위치하도록 주입컵 몸체의 내측에 체결하며, 보충액의 유입을 개폐하는 개폐밸브를 일체로 구비함으로써 별도로 구비할 필요가 없고, 펌프에 간단용이하게 조립 및 분해할 수 있게 될뿐아니라, 펌프가동시에 가동개폐구가 펌프의 내압에 의하여 자동으로 폐쇄되고, 펌프가동중단시에는 보충액고임부에 고인 보충액에 의하여 외부공기의 유입이 차단되어 펌핑액체가 고갈되지 않게되는 펌프의 보충액 주입컵을 제공하기 위한 것인 바, 이러한 본 고안을 첨부도면 제1도 내지 제3도에 의하여 상세히 설명하면 다음과 같다.The present invention is designed to solve the conventional defects as described above, the funnel-type injection cup body is fastened directly to the upper end by screwing the upper portion of the pump housing with a replenishment injection of the pump housing with a fastening tube formed at the lower end thereof. An annular projection jaw is formed to form a replenishment liquid pool around it, and on the upper portion thereof, a movable opening and closing opening or blocking of inflow of the replenishing liquid is mounted, and an injection cup body having a support hole having a distribution hole is located above the neck portion. It does not need to be provided separately by integrally equipped with an on-off valve to open and close the inflow of the replenishment liquid, it can be easily assembled and disassembled in the pump, and the opening and closing opening of the pump when the pump is running Is automatically closed by the pump and when the pump is stopped, the inflow of external air Is cut off will be described in detail by the will of the bar, this subject innovation to provide a replenishing liquid injection cup of the pump is not pumping liquid from being exhausted to the accompanying drawings, FIG. 1 to FIG. 3 as follows.

(1) When the funnel-type supplement liquid infusion cup is coupled to one side, the funnel injection cup body 2 is formed in the lower end thereof with a fastening tube 2a formed at the upper end of the supplement liquid injection passage 1a of the pump housing 1. Directly by screwing in, the annular projection projection (2f) is formed integrally in communication with the coupling tube (2a) on the bottom of the neck portion (2c) of the injection cup body (2), and the mixed projection projection (2f) The replenishment liquid pool portion 5 is formed between the circumferential wall of the neck portion 2c, and the support pin 3c is formed on the upper surface plate 3a, and the movable opening / closing hole 3 in which several distribution grooves 3b are formed on the circumferential wall is formed. The support ring 4b into which the support piece 3c is inserted is mounted on the annular protrusion 2f, and is formed in the center of the upper surface plate. And around it, it is the structure which fixed the support tool 4 in which the flow opening 4c which is opened and closed by the said movable opening and closing opening 3 is located in the upper part of the neck part 2c inside the infusion cup body 2, and is. .

또한, 상기 지지구(4)의 주벽 외주면과 주입컵 몸체(1)의 네크부(2c) 내주면에는 나사맞춤하기 위하여 나사부(4e) (2d)를 각각 형성하고, 지지구(4)의 상면판(4a)에는 체결을 위한 공구삽입홈(4f)을 형성하며, 주입컵 몸체(2)의 네크부(2c) 상측부에는 지지구(4)의 상면판(4a) 주연부가 걸리는 단턱(2e)을 형성하는 한편, 상기 가동개폐구(3)의 상면판(3a)주연부와 지지구(4)의 상면판(4a)하면에는 서로 대응하는 테이퍼면(3d) (4d)을 형성한 구성으로 되어 있다.In addition, threaded portions 4e and 2d are formed on the outer circumferential surface of the support 4 and the inner circumferential surface of the neck portion 2c of the injection cup body 1, respectively, and the upper plate of the support 4 is formed. A tool insertion groove 4f for fastening is formed at 4a, and a stepped portion 2e at which the periphery of the upper plate 4a of the support 4 is caught on the upper portion of the neck portion 2c of the injection cup body 2. On the other hand, the tapered surfaces 3d and 4d corresponding to each other are formed on the periphery of the upper plate 3a of the movable opening and closing opening 3 and the lower surface of the upper plate 4a of the support 4. .

이와같이된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above is as follows.

본 고안이 설치된 펌프를 가동하고자 하는 경우에는 가동개폐구(3)가 제2도에 가상선으로 도시한 바와같이 하향 위치에 있는 상태에서 주입컵 몸체(2)에 보충액을 주입하게 되며, 이와같이 주입된 보충액은 지지구(4)의 유통공(4c)을 통하여 유입되고 가동개폐구(3)의 유통홈(3b)을 통과한 후 환상돌출턱(2f)을 넘어 펌프하우징(1) 보충액주입로(1a)에도 유입하여 결국 펌프내에 유입된다.In the case where the present invention is intended to operate the pump, the refill solution is injected into the injection cup body 2 while the movable opening and closing opening 3 is in a downward position as shown by a virtual line in FIG. The replenishment liquid flows in through the distribution hole 4c of the support 4, passes through the distribution groove 3b of the movable opening and closing opening 3b, and then goes over the annular projection jaw 2f and the replenishment liquid injection passage 1a. ) And eventually into the pump.

이와같이 하여 펌프내에 보충액이 유입되면 펌프를 가동하고, 펌프를 가동하면 펌프의 내부압려이 상승함에 따라 가동개폐구(3)가 제2도에 실선으로 도시한 바와같이 상승하여 그 가동개폐구(3)의 상면판(3a)이 지지구(4)의 유통공(4c)을 폐쇄하게 되고, 이때 가동개폐구(3)는 테이퍼면(3d) (4d)에 의하여 정확한 위치에서 유통공(4c)을 폐쇄하게 된다.In this way, when replenishing liquid flows into the pump, the pump is operated. When the pump is operated, as the internal pressure of the pump rises, the movable opening and closing opening 3 rises as shown by the solid line in FIG. The upper surface plate 3a closes the distribution hole 4c of the support 4, and at this time, the movable opening / closing opening 3 closes the distribution hole 4c at the correct position by the tapered surfaces 3d and 4d. do.

이와같이 가동개폐구(3)가 지지구(4)의 유통공(4c)을 폐쇄하게 되면 펌프의 작동에 따른 내부압력상승에 의하여 펌핑액체가 외부로 비산됨이 방지된다.In this way, when the movable opening and closing opening 3 closes the distribution hole 4c of the support 4, the pumping liquid is prevented from scattering to the outside due to the internal pressure increase due to the operation of the pump.

한편, 배출측 밸브를 잠그고 펌프의 가동을 중단하는 경우에는 펌프의 내부압력이 떨어지면서 가동개폐구(4)가 하향으로 이동하고, 보충액고임부(5)에 환상돌출턱(2f)이 높이 만큼 보충액이 고여있게 되므로 외부공기의 유입을 차단하여 펌프내부의 펌핑액체가 역류하여 유입구측으로 빠지지 않게 되며, 이에따라 재가동하는 경우에 보충액을 다시 보충하지 않고서도 펌핑을 재개할 수 있다.On the other hand, in the case of closing the discharge valve and stopping the pump operation, as the internal pressure of the pump decreases, the movable opening / closing port 4 moves downward, and the replenishing liquid as high as the annular projection jaw 2f in the replenishing liquid pool 5 is raised. This entrapment prevents the inflow of external air so that the pumped liquid inside the pump flows backwards and does not fall into the inlet. Accordingly, when restarting, pumping can be resumed without refilling the replenishment liquid.

이상에서 설명한 바와같은 본 고안의 보충수 주입컵은 별도의 개폐밸브를 사용할 필요가 없으므로 구성이 간단화되고 주입컵 몸체의 하단부에 형성한 체결관의 외주면에 나사부를 형성한 구조이므로 사출성형시 나사부를 일체로 용이하게 성형할 수 있어 나사부 형성을 위한 별도의 후가공이 필요없으며, 주입컵 몸체의 체결관을 펌프하우징에 직접 연결하는 구조이므로 연결시 별도의 금속제 니플을 사용할 필요가 없다.As described above, the supplementary water infusion cup of the present invention does not need to use a separate on / off valve, so the configuration is simplified, and the screw portion is formed on the outer circumferential surface of the fastening tube formed at the lower end of the infusion cup body. Since it can be easily molded integrally, there is no need for a separate post-processing for forming a screw part, and the structure of connecting the fastening tube of the injection cup body directly to the pump housing does not require a separate metal nipple to be connected.

따라서 상기한 바와같은 본 고안의 보충액 주입컵은 별도의 개폐밸브와 금속제 니플의 사용을 배제하여 제품의 원가를 절감하고 황산등의 산 사용에 따른 부식 우려를 배제하며, 조립작업이 간단용이하게 되는 등의 이점이 있다.Therefore, the supplement liquid injection cup of the present invention as described above to reduce the cost of the product by eliminating the use of a separate opening and closing valve and metal nipple, to eliminate the concern of corrosion due to the use of acid, such as sulfuric acid, easy to assemble And the like.

특히, 본 고안의 보충액 주입컵은 보충액을 주입한 후 별도의 개폐밸브를 조작할 필요없이 펌프의 가동에 따르는 내압에 의하여 가동개폐판이 자동으로 보충액 주입컵을 폐쇄하므로 사용이 매우 간편하고 손에 기름, 산등이 보충액이 묻지 않게되는 이점이 있으며, 펌프가동중단시에는 보충액고임부에 보충액이 고여있어 공기의 유입을 차단하여 펌핑액체가 역류하여 고갈되는 현상을 방지하므로 역류차단을 위한 별도의 조작이 불필요한 이점등이 있다.In particular, the supplement liquid injection cup of the present invention is very easy to use and the oil in the hand because the operation opening and closing plate automatically closes the supplement liquid injection cup by the internal pressure according to the operation of the pump, without the need to operate a separate opening and closing valve after injecting the supplement liquid It has the advantage that supplementary liquid does not get on the back of the mountain, and when the pump is stopped, the supplementary liquid is accumulated in the supplementary liquid pool, which blocks the inflow of air and prevents the pumping liquid from being exhausted and exhausted. There are unnecessary benefits.
