Description

농업용 밸브{VALVE FOR AGRICULTURE}Agricultural Valves {VALVE FOR AGRICULTURE}

본 발명은 농업용 밸브에 관한 것으로서, 보다 상세하게는 밸브스템과 밸브본체 사이, 밸브볼의 관통구멍의 가장자리를 용이하게 밀봉할 수 있도록 하는 농업용 밸브에 관한 것이다.The present invention relates to an agricultural valve, and more particularly, to an agricultural valve that can easily seal the edge of the through hole of the valve ball between the valve stem and the valve body.

다수의 비닐하우스나 넓은 면적을 차지하는 밭은 통상적으로 물을 공급하는 파이프라인이 설치되어 있기 때문에, 물을 공급하는 파이프라인이 설치되며, 상기 파이프라인을 효율적으로 배치하거나 파이프라인 내의 물의 흐름을 제어하기 위하여 다수의 밸브가 설치된다.Many plastic houses or large-area fields usually have a pipeline for supplying water, so that a pipeline for supplying water is installed, and the pipeline can be efficiently arranged or to control the flow of water in the pipeline. A plurality of valves are installed for this purpose.

그래서 종래의 밸브(100)는 도 4에 도시한 바와 같이, 물의 흐름을 단속하는 밸브볼(101)이 밸브본체(102)의 내부 중앙부에 회전 가능하게 설치되고, 상기 밸브볼(101)을 회전하는 밸브스템(103)이 상기 밸브본체(102)의 상부 중앙에 돌출 형성된 스템설치부(102a)에 삽입되어 밸브스템(103)의 하단부가 상기 밸브(101)의 상부에 형성된 삽입홈(101a)에 삽입되며, 상기 밸브스템(103)의 이탈을 방지하는 스템고정너트(104)이 상기 밸브본체(102)의 스템설치부(102a)에 체결되고, 상기 밸브스템(103)의 상단부에 레버(105)가 결합되는 구조로 이루어진다.Thus, in the conventional valve 100, as shown in FIG. 4, the valve ball 101 for controlling the flow of water is rotatably installed at the inner central portion of the valve body 102, and the valve ball 101 is rotated. The valve stem 103 is inserted into the stem installation portion 102a protruding from the upper center of the valve body 102 so that the lower end of the valve stem 103 is formed in the upper portion of the valve 101. Is inserted into the stem fixing nut 104 to prevent the departure of the valve stem 103 is fastened to the stem mounting portion (102a) of the valve body 102, the upper end of the valve stem 103 lever ( 105) is a structure that is combined.

그리고 종래에는 상기 밸브볼(101)의 관통구멍(101a) 가장자리에 밀봉하는 실링(106)을 선단에 설치한 실링설치부재(107)이 상기 밸브본체(102)의 양단부에 각각 체결되며, 파이프(미도시)를 밸브(100)에 고정하는 파이프연결부재(108)가 실링설치부재(107)에 각각 체결되는 것을 포함한다.In the related art, a sealing installation member 107 having a seal 106 installed at a distal end of a sealing hole at an edge of the through hole 101a of the valve ball 101 is fastened to both ends of the valve body 102, respectively, and a pipe ( It includes a pipe connecting member 108 for fixing the valve 100 to the sealing installation member 107, respectively.

물론 상기 밸브스템(103)의 둘레면과 밸브본체(102)의 스템설치부(102a) 사이에는 실링(109)이 설치되어 상기 스템고정너트(104)의 누름에 의하여 밸브본체(102) 내의 물이 외부로 유출되지 않게 된다.Of course, a sealing 109 is installed between the circumferential surface of the valve stem 103 and the stem installation portion 102a of the valve body 102, so that the water in the valve body 102 is pushed by the stem fixing nut 104. This will not leak outside.

이와 같이 이루어지는 농업용 밸브(100)는 레버(105)를 회전하게 되면 밸브스템(103)이 회전됨과 동시에 밸브볼(101)이 회전되어 밸브본체(102)를 개폐하게 된다.Agricultural valve 100 made in this way is to rotate the lever 105, the valve stem 103 is rotated at the same time the valve ball 101 is rotated to open and close the valve body 102.

이 때 상기 밸브볼(101)이 개방되었을 경우 즉 밸브(100)를 통하여 물이 흐를 경우, 밸브(100)의 내부로 흐르는 물은 상기 밸브볼(101)의 관통구멍(101a)의 가장자리에 위치한 실링(106)에 의해 밀봉된다.In this case, when the valve ball 101 is opened, that is, when water flows through the valve 100, the water flowing into the valve 100 is located at the edge of the through hole 101a of the valve ball 101. Sealed by a sealing 106.

또한 상기 밸브볼(101)이 회전하는 도중에 밸브볼(101)의 둘레면에 위치하는 물은 상기 밸브스템(103)의 둘레면과 밸브본체(102)의 스템설치부(102a) 사이에 위치한 실링(109)에 의해 밀봉된다.In addition, the water located on the circumferential surface of the valve ball 101 while the valve ball 101 is rotated is a sealing located between the circumferential surface of the valve stem 103 and the stem installation portion 102a of the valve body 102. Sealed by 109.

그러나 종래의 농업용 밸브는 밸브볼의 관통구멍의 가장자리에 밀착되는 실링이 실링설치부재와 밸브본체의 체결력에 의하여 밀착되기 때문에, 탄력적 유격의 발생이 전혀 발생되지 않아 밸브볼과 실링의 밀착력을 조정하기 힘들고, 이에 너무 밀착될 때에 밸브볼의 회전을 원활하게 할 수 없음과 더불어 느슨하게 밀착할 때에 실링의 밀봉력이 저하된다는 단점이 있다.However, in the conventional agricultural valve, since the sealing that is in close contact with the edge of the through-hole of the valve ball is in close contact with the clamping force of the sealing installation member and the valve body, no elastic play is generated at all, and thus the adhesion between the valve ball and the sealing is adjusted. It is difficult, and when too close to this can not smoothly rotate the valve ball has a disadvantage in that the sealing force of the sealing is lowered when the close contact.

또한 종래에는 스템고정너트의 체결력에 의하여 밸브스템에 설치된 실링이 누수를 방지하기 때문에, 레버의 반복적인 작동으로 스템고정너트의 체결력이 저하되어 밸브스템 부위의 누수가 발생하기 쉽다는 단점이 있다.In addition, in the related art, since the seal installed on the valve stem is prevented from leaking due to the clamping force of the stem fixing nut, the clamping force of the stem fixing nut is lowered due to the repeated operation of the lever, so that leakage of the valve stem portion is likely to occur.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 밸브스템을 밸브본체의 내부에서 외부로 돌출되도록 설치하여 밸브스템과 밸브본체 사이를 용이하게 밀봉하고, 밸브볼의 관통구멍의 가장자리를 밀봉하는 실링을 탄력적으로 밸브볼에 밀착되도록 하여 밸브볼이 원활하게 작동될 수 있는 농업용 밸브를 제공하는 데 있다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to install the valve stem to protrude from the inside of the valve body to the outside to easily seal between the valve stem and the valve body, the valve The sealing to seal the edge of the through hole of the ball to be in close contact with the valve ball to provide an agricultural valve that can operate the valve ball smoothly.

이를 실현하기 위하여, 본 발명은 파이프와 호스, 파이프와 파이프, 호스와 호스를 연결하여 흐르는 물을 단속하는 농업용 밸브에 있어서, 밸브본체의 상부에 스템삽입부를 형성함과 더불어 내부에 실링설치부를 형성하여 상기 밸브본체의 실링설치부에 제1밸브볼실링이 배치되고, 하단부에 볼설치돌부를 형성함과 더불어 이탈방지턱을 형성하는 밸브스템이 중앙부 둘레면에 스템실링을 배치한 뒤, 상기 밸브본체의 내부에서 외부로 스템삽입부에 설치되고, 상기 밸브스템의 볼설치돌부에 대응하는 삽입슬롯을 보유하여 밸브본체의 내부에 흐르는 물을 단속하는 밸브볼이 상기 밸브본체의 내부에 위치되어 상기 밸브스템과 연결되며, 상기 밸브볼에 형성된 관통구멍의 한쪽 가장자리를 밀봉하는 밀봉수단이 상기 밸브본체의 한쪽 개구부분에 삽입되고, 내부에 밀봉수단과 밀착되는 밀착면을 보유한 연결구가 상기 밀봉수단을 밸브볼 쪽으로 밀면서 상기 밸브본체의 한쪽 단부에 체결되며, 밸브스템을 회전하는 레버가 상기 밸브스템의 상단부에 결합되는 것으로 이루어지는 농업용 밸브를 제공한다.In order to realize this, the present invention in the agricultural valve for controlling the water flowing by connecting the pipe and hose, pipe and pipe, hose and hose, forming a stem insert portion in the upper portion of the valve body, and forming a sealing installation portion therein The first valve ball sealing is disposed in the sealing installation portion of the valve body, and the valve stem forming the separation prevention jaw is formed at the lower end, and the stem stem is disposed on the circumferential surface of the valve body.

여기서 상기 밸브본체(11)에는 스템삽입부(11a)가 상부에 형성됨과 더불어 실링설치부(11b)가 내부에 형성되며, 상기 밸브본체(11)의 실링설치부(11b)에 제1밸브볼실링(16)이 배치된다.The valve body 11 has a stem insertion portion 11a formed thereon and a sealing installation portion 11b formed therein, and a first valve ball in the sealing installation portion 11b of the valve body 11. The seal 16 is arranged.

상기 밸브스템(12)에는 볼설치돌부(12a)가 하단부에 형성됨과 더불어 이탈방지턱(12b)이 형성되고, 중앙부 둘레면에 스템실링(17)을 배치하게 되는 바, 상기 밸브스템(12)을 상기 밸브본체(11)의 내부에서 외부로 스템삽입부(11a)에 설치하게 된다.The valve stem 12 has a ball installation protrusion 12a formed at a lower end thereof, and a separation preventing jaw 12b is formed, and the stem sealing 17 is disposed at the center circumferential surface of the valve stem 12. It is installed in the stem insert portion (11a) from the inside of the valve body (11) to the outside.

상기 밸브볼(13)에는 도 2와 도 3에 도시한 바와 같이, 상기 밸브스템(12)의 볼설치돌부(12a)에 대응하는 삽입슬롯(13a)이 형성됨과 더불어 상기 밸브본체(11)의 내부의 물을 관통시키는 관통구멍(13b)이 형성되며, 상기 밸브볼(13)을 상기 밸브본체(11)의 내부에 위치시켜 상기 밸브스템(12)과 연결하게 된다.As shown in FIG. 2 and FIG. 3, the valve ball 13 has an insertion slot 13a corresponding to the ball mounting protrusion 12a of the valve stem 12 and the valve body 11 of the valve body 11. A through hole 13b penetrating the water therein is formed, and the valve ball 13 is positioned inside the valve body 11 to connect with the valve stem 12.

이 때 상기 밸브스템(12)과 밸브볼(13)의 연결 상태를 용이하게 유지하기 위하여, 상기 밸브스템(12)의 볼설치돌부(12a)와 상기 밸브볼(13)의 삽입슬롯(13a)의 단면을 사다리꼴 형상으로 형성함이 바람직하다.At this time, in order to easily maintain the connection state between the valve stem 12 and the valve ball 13, the insertion slot (13a) of the ball mounting protrusion (12a) and the valve ball 13 of the valve stem 12 It is preferable to form the cross section of the trapezoidal shape.

한편 상기 밀봉수단은 상기 밸브볼(13)에 형성된 관통구멍(13b)의 한쪽 가장자리를 밀봉할 수 있도록 상기 밸브본체(11)의 한쪽 개구부분에 삽입되며, 상기 연결구(14)는 내부에 밀봉수단과 밀착되는 밀착면(14a)을 보유하여 상기 밀봉수단을 밸브볼(13) 쪽으로 밀면서 상기 밸브본체(11)의 한쪽 단부에 체결된다.The sealing means is inserted into one opening of the valve body 11 so as to seal one edge of the through hole 13b formed in the valve ball 13, and the connector 14 is sealed therein. The contact surface 14a is in close contact with and is pushed to one end of the valve body 11 while pushing the sealing means toward the valve ball 13.

더우기 본 발명의 밀봉수단은 한쪽 면의 내측과 외측에 실링설치부(21a,21b)를 각각 형성함과 더불어 다른쪽 면에 실링설치부(21c)를 형성하여 상기 밸브본체(11)에 삽입되는 실링설치구(21), 상기 실링설치구(21)의 한쪽 면의 내측에 형성된 실링설치부(21a)에 배치되어 상기 제1밸브볼실링(16)과 함께 상기 밸브볼(13)의 관통구멍(13b) 가장자리를 밀봉하는 제2밸브볼실링(22), 상기 실링설치구(21)의 한쪽 면의 외측에 형성된 실링설치부(21b)에 배치되어 실링설치구(21)와 밸브본체(11) 사이를 밀봉하는 제1실링(23), 상기 실링설치구(21)의 다른쪽 면에 형성된 실링설치부(21c)에 배치되어 상기 연결구(14)의 밀착면(14a)에 밀착되는 제2실링(24)으로 이루어진다.In addition, the sealing means of the present invention is formed into the sealing body (21a, 21b) on the inside and the outside of one side, respectively, and to form the sealing installation portion (21c) on the other side is inserted into the valve body (11) The through hole of the valve ball 13 together with the first valve ball seal 16 is disposed in the seal mounting portion 21 and the seal mounting portion 21a formed on the inner side of one surface of the seal mounting hole 21. 13b is disposed in the second valve ball sealing 22 sealing the edge and the sealing installation portion 21b formed on the outer side of one surface of the sealing installation portion 21 to seal the installation portion 21 and the valve body 11. ) A second sealing 23 for sealing between the second, the second sealing member 21c formed on the other surface of the sealing fitting 21 is in close contact with the contact surface 14a of the connector 14 It consists of a seal 24.

물론 본 발명에 의한 농업용 밸브는 종래와 마찬가지로 파이프 또는 호스를 밸브(1)에 고정하는 파이프연결부재(25)를 상기 밸브본체(11)의 한쪽 단부에 체결된 연결구(14)와 상기 밸브본체(11)의 다른쪽 단부에 각각 체결하게 된다.Of course, the agricultural valve according to the present invention is a connector 14 and the valve main body (14) fastened to one end of the valve body 11, the pipe connecting member 25 for fixing the pipe or hose to the valve 1 as in the prior art ( 11) to the other end of each.

또한 상기 파이프연결부재(25)가 체결되는 상기 연결부(14)의 일측이 수나사를 형성하게 되나, 이 수나사를 암나사로 형성할 수 있음은 자명하다.In addition, one side of the connecting portion 14 to which the pipe connecting member 25 is fastened to form a male screw, but it is obvious that the male screw may be formed as a female screw.

이와 같이 이루어지는 농업용 밸브(1)는 레버(15)를 회전하게 되면 밸브스템(12)이 회전됨과 동시에 밸브볼(13)이 회전되어 밸브본체(11)를 개폐하게 된다.When the agricultural valve 1 is formed in this way, when the lever 15 is rotated, the valve stem 12 is rotated and the valve ball 13 is rotated to open and close the valve body 11.

이 때 상기 밸브볼(13)이 개방되었을 경우 즉 밸브(1)를 통하여 물이 흐를 경우, 밸브(1)의 내부로 흐르는 물이 상기 밸브볼(3)의 관통구멍(13b)의 가장자리에 각각 위치한 실링(16,22)에 의해 밀봉된다.At this time, when the valve ball 13 is opened, that is, when water flows through the valve 1, water flowing into the valve 1 is formed at the edge of the through hole 13b of the valve ball 3, respectively. It is sealed by located seals 16 and 22.

여기서 상기 실링(16,22)과 밸브볼(3) 사이의 밀착력은 연결구(14)의 밀착면(14a)이 제2실링(24)을 누르는 힘에 의하여 좌우되므로 제2실링(24)의 탄력으로 인하여 매우 적적하게 발생된다.In this case, the adhesion between the seals 16 and 22 and the valve ball 3 depends on the force of the pressing surface 14a of the connector 14 to press the second seal 24 so that the elasticity of the second seal 24 may be reduced. Very appropriately.

따라서 상기 실링(16,22)과 밸브볼(3) 사이의 적당한 밀착력으로 인하여, 밸브볼(3)이 원활하게 회전된다.Thus, due to the proper adhesion between the seals 16 and 22 and the valve ball 3, the valve ball 3 rotates smoothly.

한편 상기 밸브볼(13)이 회전하는 도중에 밸브볼(13)의 둘레면에 위치하는 물은 상기 밸브스템(12)의 둘레면과 밸브본체(11)의 스템설치부(11a) 사이에 위치한 스템실링(17)에 의해 밀봉된다.Meanwhile, the water located on the circumferential surface of the valve ball 13 while the valve ball 13 is rotating is a stem located between the circumferential surface of the valve stem 12 and the stem installation portion 11a of the valve body 11. It is sealed by the seal 17.

물론 상기 밸브스템(12)과 밸브볼(13)의 연결 부분의 단면, 밸브스템(12)의 이탈방지턱(12b)에 의하여 밸브스템(12)이 밸브본체(11)의 외부로 이탈되지 않게 되며, 밸브(1) 내부의 물의 압력이 밸브스템(12)의 이탈방지턱(12b)과 밸브본체(11)의 내부면 사이의 틈에 의하여 저감된 상태에서 스템실링(17)에 도달하게 되므로 밸브스템(12) 부분이 용이하게 밀봉되는 것이다.Of course, the valve stem 12 is prevented from escaping to the outside of the valve body 11 by the end surface of the connection portion of the valve stem 12 and the valve ball 13 and the release prevention jaw 12b of the valve stem 12. Since the pressure of the water in the valve 1 reaches the stem sealing 17 in a state of being reduced by the gap between the release preventing projection 12b of the valve stem 12 and the inner surface of the valve body 11, the valve stem 17 (12) The part is easily sealed.

이렇게 본 발명의 밸브(1)는 밸브볼(13)이 원활하게 회전될 수 있음과 아울러 각각의 누수 부분이 용이하게 밀봉된 것이다.Thus, the valve 1 of the present invention is that the valve ball 13 can be rotated smoothly, and each leakage portion is easily sealed.

이상 설명한 바와 같이, 본 발명에 의한 농업용 밸브는 밸브스템을 밸브본체의 내부에서 외부로 돌출되도록 설치하여 밸브스템의 느슨함이 발생되지 않기 때문에 밸브스템과 밸브본체 사이를 용이하게 밀봉함과 더불어 밸브스템의 작동을 원활하게 하고, 연결구의 밀착면이 밀봉수단의 제2실링을 밀어서 제1,2밸브볼실링이 밸브볼의 관통구멍의 가장자리를 탄력적으로 밀봉하기 때문에 밸브볼과 제1,2밸브볼실링 사이의 밀착력과 밀봉능력을 조정할 수 있어 밀봉 능력을 유지하면서도 밸브볼의 작동을 원활하게 할 수 있다는 이점이 있다.As described above, the agricultural valve according to the present invention installs the valve stem so as to protrude from the inside of the valve body to the outside, so that the valve stem is not loosely formed, and the valve stem is easily sealed between the valve body and the valve body. The valve ball and the first and second valves are smoothly operated and the contact surface of the connector pushes the second seal of the sealing means so that the first and second valve ball seals elastically seal the edge of the through hole of the valve ball. Adhesion between the ball sealing and the sealing ability can be adjusted to have the advantage of smooth operation of the valve ball while maintaining the sealing ability.
