Description

동력 분무기의 밸브 장착구조Valve mounting structure of power sprayer

본 고안은 동력 분무기에 관한 것으로, 더 상세하게는 밸브의 장착구조를 개선하여 실린더블록이 압력에 의해 파손되는 것을 방지할 수 있도록 한 동력 분무기의 밸브 장착구조에 관한 것이다.The present invention relates to a power sprayer, and more particularly to a valve mounting structure of the power sprayer to improve the mounting structure of the valve to prevent the cylinder block from being damaged by pressure.

일반적으로 동력 분무기는 경운기 동력에 의해 작동되는 것으로, 이러한 분무기(1)의 흡입구측에는 도 1과 도 2에 도시되는 바와 같이 그 내부에 다수개의 피스톤이 왕복운동하도록 설치된 실린더블록(2)과, 상기 실린더블록(2)에 기밀하게 체결되는 흡입관(3)과, 상기 실린더블록(2)과 흡입관(3) 사이에 설치되어 피스톤의 왕복행정에 따라서 개폐되는 밸브(4)가 설치된다.In general, the power sprayer is operated by the tiller power, the inlet side of the sprayer 1, as shown in Figs. 1 and 2 cylinder block (2) installed to reciprocate therein, and A suction pipe 3 which is tightly fastened to the cylinder block 2 and a valve 4 which is installed between the cylinder block 2 and the suction pipe 3 and opened and closed according to the reciprocating stroke of the piston are installed.

종래의 밸브 장착구조는 도 2에 도시되는 바와 같이, 상기 밸브(4)에 끼워져 고정된 밸브패킹(4a)이 흡입관(3)의 흡입구(3a)에 압입된 상태에서 밸브(4)가 실린더블록(2)의 유입구(2a)에 내장되는 구조로 장착된다. 이때 상기 흡입관(3)의 흡입구(3a)에는 밸브패킹(4a)이 기밀하게 끼워지는 패킹삽입부(3b)가 형성되고, 상기 실린더블록(2)의 유입구(2a)에는 흡입관(3)의 패킹삽입부(3b)로 끼워지면서 밸브패킹(4a)에 기밀하게 밀착되는 환돌기(2b)가 형성된다.In the conventional valve mounting structure, as shown in FIG. 2, the valve block 4a is inserted into the valve 4, and the valve block 4a is pressurized into the inlet port 3a of the suction pipe 3. It is mounted in a structure built in the inlet port 2a of (2). In this case, a packing inserting portion 3b is formed in the inlet 3a of the suction pipe 3 to seal the valve packing 4a in an airtight manner, and the packing of the suction pipe 3 is provided at the inlet 2a of the cylinder block 2. An annular projection 2b is formed to be hermetically adhered to the valve packing 4a while being fitted into the insertion portion 3b.

그러나, 이러한 종래의 밸브 장착구조는 그 구조상 밸브(4)가 내장되는 실린더블록(2)의 유입구(2a) 길이가 짧아 피스톤의 왕복행정시 발생하는 압력을 이 유입구(2a)가 견디지 못하므로, 특히 유입구(2a)의 환돌기(2b)부위가 쉽게 깨지는 문제점이 있었다.However, such a conventional valve mounting structure has a short length of the inlet port 2a of the cylinder block 2 in which the valve 4 is built, so that the inlet port 2a cannot withstand the pressure generated during the reciprocating stroke of the piston. In particular, there was a problem that the portion of the inlet (2a) of the annular projection (2b) is easily broken.

본 고안의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해 안출한 것으로, 실린더블록과 흡입관 사이에 내장되는 밸브의 장착구조를 개선하여 실린더블록의 유입구부위가 압력에 의해 파손되는 것을 방지할 수 있도록 한 동력 분무기의 밸브 장착구조를 제공하는 데 있다.An object of the present invention is to solve the conventional drawbacks as described above, by improving the mounting structure of the valve built between the cylinder block and the suction pipe can prevent the inlet portion of the cylinder block is damaged by pressure. To provide a valve mounting structure for a power sprayer.

상기 목적을 달성하기 위해 본 고안은 밸브가 내장되는 실린더블록의 유입구 길이를 연장하고, 이 연장된 유입구에 밸브패킹이 끼워지는 패킹삽입부를 형성하여, 상기 연장된 유입구가 피스톤 압력에 충분히 견딜 수 있도록 한 것이다.In order to achieve the above object, the present invention extends the length of the inlet of the cylinder block in which the valve is built, and forms a packing insert into which the valve packing is fitted, so that the extended inlet can withstand the piston pressure. It is.

이하 첨부된 도면에 따라서 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail according to the accompanying drawings.

본 고안 동력 분무기의 밸브 장착구조는 도 3에 도시되는 바와 같이, 실린더블록(20)의 유입구(21)와 흡입관(30)의 흡입구(31) 사이에 밸브(40)가 장착되는 분무기에 있어서, 상기 유입구(21)를 연장하여 그 내경에 밸브(40)를 내장하되, 유입구(21)에 밸브패킹(41)이 기밀하게 끼워지는 패킹삽입부(22)를 형성하고, 상기 흡입관(30)의 흡입구(31)에는 패킹삽입부(22)로 끼워지면서 밸브패킹(41)에 기밀하게 밀착되는 환돌기(32)를 형성하여 구성된 것을 그 기술적 구성상의 특징으로 한다.The valve mounting structure of the power sprayer of the present invention is, as shown in Figure 3, in the sprayer in which the valve 40 is mounted between the inlet port 21 of the cylinder block 20 and the suction port 31 of the suction pipe 30, The inlet 21 is extended to embed the valve 40 in the inner diameter thereof, and a packing inserting portion 22 is formed in the inlet 21 in which the valve packing 41 is hermetically inserted. The inlet 31 is formed by forming a ring projection 32 which is tightly fitted to the valve packing 41 while being inserted into the packing inserting portion 22 is characterized by its technical configuration.

여기서, 상기 실린더블록(20)의 유입구(21)는 그 길이가 일체로 연장되므로 인해 연장부가 형성된다.Here, the inlet 21 of the cylinder block 20 is formed because of its extension is integrally extended.

상기 실린더블록(20)과 흡입관(30)은 다수개의 볼트체결로 기밀하게 결합된다.The cylinder block 20 and the suction pipe 30 are hermetically coupled with a plurality of bolted fastenings.

이와 같이 구성된 본 고안은 밸브(40)가 실린더블록(20)의 유입구(21)내에 내장된 상태에서 밸브패킹(41)이 유입구(21)의 패킹삽입부(22)에 끼워져 압입되는 구조로 장착되고, 이때 실린더블록(20)의 유입구(21)는 연장부를 통해 그 길이가 연장되므로 피스톤의 왕복행정시 발생하는 압력을 유입구(21)가 충분히 견딜수 있다.The present invention configured as described above is mounted in a structure in which the valve packing 41 is fitted into the packing inserting portion 22 of the inlet 21 in a state in which the valve 40 is embedded in the inlet 21 of the cylinder block 20. At this time, since the inlet 21 of the cylinder block 20 extends through its extension, the inlet 21 can withstand the pressure generated during the reciprocating stroke of the piston.

따라서, 이러한 본 고안은 밸브(40)와 밸브패킹(41)이 실린더블록(20)에 형성된 유입구(21)와 패킹삽입부(22)에 장착되고, 밸브(40)가 내장된 상기 유입구(21)의 길이가 길기 때문에 압력에 충분히 견딜 수 있기 때문에, 특히 종래와 같이 실린더블록(20)의 유입구(21)부위가 피스톤 압력에 의해 깨지는 문제점을 근본적으로 해소할 수 있는 장점이 있다.Thus, the present invention is the valve 40 and the valve packing 41 is mounted to the inlet 21 and the packing inserting portion 22 formed in the cylinder block 20, the valve 40 is built in the inlet 21 Because of the long length of)) can withstand the pressure sufficiently, there is an advantage that can fundamentally solve the problem that the inlet portion 21 of the cylinder block 20 is broken by the piston pressure as in the prior art.

이상에서 살펴본 바와 같이 본 고안 동력 분무기의 밸브 장착구조는 실린더블록의 유입구 길이가 연장되므로 이 유입구부위가 피스톤 압력에 의해 파손되는 것을 미연에 방지할 수 있는 매우 유용한 고안이다.As described above, the valve mounting structure of the present invention power sprayer is a very useful design that can prevent the inlet portion from being damaged by the piston pressure because the inlet length of the cylinder block is extended.
