Abstract

The present invention relates to an automatic pressure valve for water supply in a water storage tank. More particularly, the present invention relates to an automatic pressure valve for water supply in a water storage tank that is designed to increase the water supply by using the water supply pressure added to a water supply line of another storage tank when desalination of some water tanks is completed in the process of desalination of water supplied from water pipes in a water tank such as a multi-reservoir installed with multiple water tanks.

Description

저수조의 급수량 자동 가압밸브{the water supply automatic pressure valve of the water tank}The water supply automatic pressure valve of the water tank

본 발명은 저수조의 급수량 자동 가압밸브에 관한 것으로, 더욱 상세하게는 다수의 저수조가 설치된 공동주택 등의 저수조에 상수관으로부터 공급받은 용수를 담수하는 과정에서 일부 저수조의 담수 완료시 다른 저수조의 급수라인으로 부가되는 급수압력을 이용하여 급수량을 증가시킬 수 있도록 한 저수조의 급수량 자동 가압밸브에 관한 것이다. The present invention relates to an automatic pressurization valve for water supply of a water tank, and more particularly, in the process of desalination of water supplied from a water pipe in a water tank such as an apartment house in which a plurality of water tanks are installed, a water supply line of another water tank when desalination of some water tanks is completed It relates to an automatic water supply pressure valve of a water storage tank that can increase the water supply by using the added water pressure.

일반적으로 세대수가 많은 아파트와 같은 공동주택에는 세대수가 많고 고층으로 매우 높기 때문에 상수도의 용수를 각 세대로 직접 연결하여 공급하기에는 수압과 수량이 부족하여 급수에 문제가 있으므로 통상 공동주택의 급수 시스템은 저수조에 계획된 급수량의 용수를 저장하여 각 세대로 공급하는 방식을 사용하고 있다. In general, apartment houses with a large number of households, such as apartments, have many households and are very high, so there is a problem with water supply due to insufficient water pressure and quantity to directly connect and supply water from the tap water to each household. A method of storing the planned amount of water in the house and supplying it to each household is used.

저수조는 세대수가 많은 공동주택의 경우 한 개 이상 다수개의 저수조를 옥상 및 지하 등에 설치하여 상수도 급수배관을 통해 공급되는 용수를 분기관을 통해 저수조에 담수하게 되는 데, 보통 분기관은 상수도 급수배관보다 작은 직경으로 이루어지고 급수배관으로부터 공급되는 용수는 분기관을 통해 다수개의 저수조에 일정하게 분할 급수되어 저장된다. As for the water tank, in the case of an apartment house with a large number of households, one or more water tanks are installed on the roof and underground to freshen the water supplied through the water supply pipe to the water tank through the branch pipe. It is made of a small diameter and the water supplied from the water supply pipe is uniformly divided and stored in a plurality of water storage tanks through a branch pipe.

따라서, 용수를 담수한 저수조는 각 세대별로 용수를 공급하게 되는 데 용수가 세대별 사용으로 일정 수위로 낮아지면 센서의 감지에 의해 급수배관으로부터 용수가 공급되어 다시 담수 되는 과정을 반복하게 된다. Therefore, the water storage tank that contains fresh water supplies water to each household, and when the water is lowered to a certain level due to the use of each household, the water is supplied from the water supply pipe by the sensor's detection and the process of being fresh again is repeated.

그런데 각 저수조의 담수량은 세대별 사용량의 차이에 따라 만수위까지의 급수량과 급수시간의 차이가 발생하여 어떤 저수조는 일찍 만수위가 되는 반면에 다른 저수조는 보다 늦게 만수위가 된다. However, as for the amount of fresh water in each storage tank, there is a difference in the amount of water supplied to the full water level and the water supply time according to the difference in usage by household.

그러나 급수배관으로부터 공급되는 용수의 급수압력은 각 저수조에 일정하게 작용하므로 일부 저수조가 만수위가 되어 급수가 차단되어도 다른 저수조에 미치는 급수압력은 일부 높아지지만, 급수량은 계획된 유량으로 동일하게 공급되므로 급수시간이 오래 걸리는 문제가 있다. However, since the water supply pressure of the water supplied from the water supply pipe is uniformly applied to each water tank, even if some water tanks reach the full water level and the water supply is blocked, the water pressure applied to other water tanks increases, but the water supply is supplied at the same flow rate, so the water supply time I have a problem with this taking a long time.

본 발명의 목적은 종래의 문제점을 해결하기 위한 데 있는 것으로 급수배관으로부터 분기관을 통해 연결되는 다수개의 저수조에 용수를 담수하는 과정에서 일부 저수조가 만수위가 되어 담수 완료되는 경우 다른 저수조의 급수라인으로 부가되는 급수압력을 이용하여 보다 많은 양의 급수량을 다른 저수조로 공급할 수 있도록 한 저수조의 급수량 자동 가압밸브를 제공하는 데 있다. An object of the present invention is to solve the problems of the prior art. In the process of desalination of water into a plurality of water storage tanks connected from a water supply pipe through a branch pipe, when some of the water tanks reach the full water level and the desalination is completed, the water supply line of another water tank An object of the present invention is to provide an automatic water supply pressure valve of a water storage tank that can supply a larger amount of water supply to another water storage tank by using the added water supply pressure.

본 발명의 저수조의 급수량 자동 가압밸브는 도 3에 도시된 바와 같이, 급수배관(50)으로부터 각 저수조(W)로 분기되는 분기관(51)에 각각 설치되어 급수압력에 따라 유량을 증가시키는 것으로, 도 1 내지 도 2에 도시된 바와 같이, 양측에 계획된 유량보다 큰 직경의 유입구(1)와 유출구(2)를 형성한 밸브하우징(10)과, 상기 유입구(1)와 유출구(2)의 사이에 형성된 제1유로(L1)와, 상기 제1유로(L1)와 격벽(3)을 사이에 두고 이중의 유로를 형성하는 제2유로(L2)와, 상기 격벽(3)에 관통되어 제1유로(L1)와 제2유로(L2)를 연통하는 밸브공(4)과, 상기 밸브공(4)에 설치된 밸브시트(5)와, 상기 밸브공(4)을 급수압력의 증가시 개폐자재하는 디스크(6)와, 상기 디스크(6)의 스템(6')과 벨브하우징의 삽입관(11)에 끼워져 디스크(6)를 하향 탄지하는 스프링(12)과, 제1유로(L1)의 사이에 설치되어 유량을 감소시키는 다수개의 통수공(13)을 가진 유량제어플레이트(14)와, 디스크(6)의 일측에 수직으로 관통되어 제2유로(L2)에 공기가 충진되는 것을 방지하는 적은 직경의 수로(15)를 포함하여 이루어진다. As shown in FIG. 3, the water supply automatic pressure valve of the water storage tank of the present invention is installed in the branch pipe 51 branching from the water supply pipe 50 to each water storage tank W, respectively, to increase the flow rate according to the water supply pressure. , as shown in FIGS. 1 to 2, a valve housing 10 having an inlet 1 and an outlet 2 having a larger diameter than the planned flow rate on both sides, and the inlet 1 and the outlet 2 A first flow path L1 formed therebetween, a second flow path L2 that forms a double flow path with the first flow path L1 and the partition wall 3 interposed therebetween, and a second flow passage passing through the partition wall 3 The valve hole 4 communicating with the first flow passage L1 and the second flow passage L2, the valve seat 5 installed in the valve hole 4, and the valve hole 4 are opened and closed when the water supply pressure increases A free disk 6, a spring 12 inserted into the stem 6' of the disk 6 and the insertion tube 11 of the valve housing to push the disk 6 downward, and a first flow path (L1) It is installed between the flow control plate 14 having a plurality of water-through holes 13 to reduce the flow rate, and the disk 6 is vertically penetrated to one side to prevent the second flow path L2 from being filled with air. and comprises a small diameter channel 15 .

상기 제1유로(L1)와 제2유로(L2)를 연통시키는 밸브공(4)을 개폐자재하는 디스크(6)는 스프링(12)의 하향 탄발력에 의해 하강되어 평상시 밸브공(4)을 차단하고, 유입구(1)로 유입되는 급수압력이 계획된 급수압력보다 높아질 때 디스크(6)가 스프링(12)을 압축시키면서 밸브공(4)을 개방하여 용수가 제1유로(L1)와 제2유로(L2)를 통해 동시에 유입되게 하고 유입된 용수는 합쳐져 유출공으로 유출되고 저수조(W)에 담수되도록 구성되어 있다. The disc 6 that freely opens and closes the valve hole 4 connecting the first flow passage L1 and the second flow passage L2 is lowered by the downward elastic force of the spring 12 to close the valve hole 4 in normal times. When the water supply pressure flowing into the inlet 1 becomes higher than the planned water supply pressure, the disk 6 compresses the spring 12 and opens the valve hole 4 to allow water to flow through the first flow path L1 and the second It is made to flow simultaneously through the flow path (L2), and the inflow water is combined and discharged to the outlet hole, and is configured to be fresh water in the water storage tank (W).

여기서 스프링(12)의 탄지력은 유입공을 통해 유입되는 용수의 계획된 급수압력보다 약간 크게 형성되어 평상시 제1유로(L1)를 통해 용수가 흐를 때에는 밸브공(4)을 차단하고, 계획된 용수압력보다 큰 급수압력이 작용할 때에만 개방되어 진다Here, the elastic force of the spring 12 is formed slightly larger than the planned water supply pressure of the water flowing in through the inlet hole, so that when water normally flows through the first flow path L1, the valve hole 4 is blocked, and the planned water pressure Opens only when greater water pressure is applied

또한, 본 발명의 유입구(1)와 유출구(2)는 계획된 급수량이 통과할 수 있는 직경보다 2배 정도 크게 형성되어 제1유로(L1)와 제2유로(L2)로 합쳐져 유출되는 급수용량을 수용할 수 있도록 구성되어 있다. In addition, the inlet (1) and outlet (2) of the present invention are formed to be about twice as large as the diameter through which the planned water supply can pass, so that the water supply capacity flowing out is combined into the first flow path (L1) and the second flow path (L2). It is designed to accommodate.

그러나 유입구(1)로 유입된 용수의 급수압력이 증가되지 않은 평상시에는 다수개의 저수조(W)에 일정하게 물을 담수할 수 있도록 계획된 유량이 배출될 수 있도록 제1유로(L1)의 중간에 다수개의 통수공(13)이 관통된 유량제어플레이트(14)가 설치되어 유입구(1)로 유입된 용수가 유량제어플레이트(14)에 부딪히면서 통수공(13)을 통해 유출되는 과정에서 유량이 감소되도록 되어 있다. However, in normal times when the water supply pressure of the water introduced into the inlet 1 is not increased, a plurality of water flows in the middle of the first flow path L1 can be discharged so that the planned flow rate can be constantly stored in the plurality of water storage tanks W. The flow rate control plate 14 through which the water holes 13 are penetrated is installed so that the water flowing into the inlet 1 collides with the flow control plate 14 so that the flow rate is reduced in the process of flowing out through the water holes 13 has been

이는 본 발명의 유입구(1)와 유출구(2)가 계획 유량보다 2배 이상 크게 형성되어 있으므로 다수개의 저수조(W)에 고르게 분배되어 담수되지 않고 일부 저수조(W)에 많이 담수됨에 따라 용수가 계획된 유량의 압력으로 균등한 공급이 되지 않는 것을 방지하기 위함이다. This is because the inlet (1) and outlet (2) of the present invention are formed to be twice as large as the planned flow rate, so the water is not evenly distributed to a plurality of storage tanks (W) and is not freshly received. This is to prevent an even supply by the pressure of the flow rate.

또한, 디스크(6)에 수직으로 관통된 수로(15)는 제1유로(L1)에서 흐르는 물이 수로(15)를 통해 제2유로(L2)로 소량의 양이 지속적으로 배출되도록 함으로써 제2유로(L2)에 공기가 차이는 것을 방지하여 디스크(6)의 원활한 작동을 가능하게 한다.In addition, the water channel 15 penetrating vertically through the disk 6 allows the water flowing from the first flow channel L1 to continuously discharge a small amount to the second flow channel L2 through the water channel 15, so that the second It prevents the air from forming in the flow path L2 to enable smooth operation of the disk 6 .

즉, 제2유로(L2)가 디스크(6)에 의해 하강되어 밸브공(4)을 차단한 상태에서는 제2유로(L2)에 공기가 차게 되어 디스크(6)가 상승되지 않게 되므로 수로(15)를 통해 상시 소량의 물이 통하도록 함으로써 디스크(6)의 상승을 원활하게 할 수 있다. That is, in the state where the second flow path L2 is lowered by the disk 6 and the valve hole 4 is blocked, the second flow passage L2 is filled with air and the disk 6 does not rise, so the water passage 15 ) to allow a small amount of water to pass through at all times, so that the disk 6 can be raised smoothly.

이와 같이 본 발명은 전기한 바와 같이 각 급수배관(50)과 저수조(W)의 연결배관에 각각 설치되어 저수조(W)에 유입되는 유량을 필요시에 증가시키는 것으로 도 3에 도시된 종래의 구조에 따르면 3개의 저수조(W)에 물을 담수하는 과정에서 3개의 저수조(W)에 동시에 물을 담수하는 경우에는 일정한 급수압력이 작용하여 물이 담수 되지만, 어느 한쪽의 저수조(W)가 만수위가 되면 3개로 분리 공급되는 물의 급수압력이 2개에만 작용하여 급수압력만 일부 높아지게 될 뿐 급수량은 동일하여 높아지는 급수압력을 다른 저수조(W)로 부가시켜 급수량을 증가시킬 수 없는 문제가 있다. As described above, the present invention is installed in the connection pipe of each water supply pipe 50 and the water storage tank W to increase the flow rate flowing into the water storage tank W when necessary, as described above. The conventional structure shown in FIG. According to [1], in the case of adding water to three water tanks (W) at the same time in the process of freshening water into three water tanks (W), a constant water supply pressure is applied to fresh water. When the water supply pressure of the water separately supplied into three parts acts only on two parts, only the supply water pressure is partially increased, but the water supply quantity is the same.

그러나 본 발명은 유입구(1)와 유출구(2)의 직경을 계획유량보다 크게 형성하고 밸브하우징(10)의 내부에 기존의 제1유로(L1)와 또 다른 제2유로(L2)를 이중으로 형성하여 평상시에는 계획된 유량만큼 용수가 제1유로(L1)를 통해 유출되고, 저수조(W)의 물 담수량에 따라 급수압력이 일부 높이질 때 부가된 높은 급수압력에 의해 밸브공(4)을 차단하고 있는 디스크(6)를 상승시켜 밸브공(4)을 개방시킴으로써 제2유로(L2)로도 용수가 유입되어 제1유로(L1)로 유입된 용수와 합쳐진 후 유출구(2)로 유출되므로 유량이 대폭 증가되어 급수량이 많아지고 급수시간도 단축되는 효과를 제공하게 된다. However, in the present invention, the diameter of the inlet (1) and the outlet (2) is formed to be larger than the planned flow rate, and the existing first flow path (L1) and another second flow path (L2) are doubled inside the valve housing (10). In normal times, water flows out through the first flow path (L1) as much as the planned flow rate, and the valve hole (4) is blocked by the high water supply pressure added when the water supply pressure is partially increased according to the amount of water in the water storage tank (W). By raising the disc 6 and opening the valve hole 4, water flows into the second flow path L2, is combined with the water flowed into the first flow path L1, and flows out to the outlet 2, so that the flow rate is increased. It greatly increases the amount of water supplied and provides the effect of shortening the water supply time.

밸브공(4)을 개방한 디스크(6)는 유입공을 통해 유입되는 급수압력이 원래대로 낮아지게 되면 스프링(12)의 탄발복귀력에 의해 하강되어 밸브공(4)을 차단하게 되고 이같이 디스크(6)가 차단된 상태에서는 수로(15)를 통해 소량의 물이 제2유로(L2)로 지속적으로 유입되므로 제2유로(L2)에 공기가 충진되는 것을 방지하여 디스크(6)의 상승을 방해하지 않게 된다. The disc 6 with the valve hole 4 opened is lowered by the resilient return force of the spring 12 when the water supply pressure flowing in through the inlet hole is lowered to its original state to block the valve hole 4, and as such, the disk In the state in which (6) is blocked, a small amount of water continuously flows into the second passage (L2) through the water passage (15), so the second passage (L2) is prevented from being filled with air to prevent the disk (6) from rising. will not interfere.

또한, 급수압력이 부가되지 않은 평상시의 흐름에서는 제1유로(L1)로 흐르는 유량이 계획유량보다 많으므로 다수개의 저수조(W)에 균등하게 공급할 수 없으나, 이는 제1유로(L1)에 설치된 유량제어플레이트(14)에 의해 유출량이 감량되어 유출됨에 따라 저수조(W)에 균등한 공급을 할 수 있다. In addition, in the normal flow to which no water supply pressure is applied, the flow rate flowing into the first flow path L1 is greater than the planned flow rate, so it is not possible to evenly supply the plurality of water storage tanks W, but this is the flow rate installed in the first flow path L1. As the amount of outflow is reduced by the control plate 14 and flows out, it is possible to uniformly supply the water storage tank (W).

즉, 상기 유량제어플레이트(14)에는 다수개의 통수공(13)이 관통되어 있으므로 유입구(1)로 유입된 용수는 유량제어밸브에 부딪히게 되면서 통수공(13)을 통해 일부만 통과하게 되므로 유입된 전체량을 유출시키지 않고 적당한 양만을 유출시킬 수 있는 것이다. That is, since a plurality of water holes 13 are penetrated in the flow control plate 14, the water flowing into the inlet 1 collides with the flow control valve and only partially passes through the water holes 13. It is possible to drain only an appropriate amount without spilling the entire amount.

이와 같이 본 발명은 다수개의 저수조(W) 중에서 일부가 만수위가 되면 이에 작용하는 압력을 다른 저수조(W)의 급수압력에 부가시켜 급수량을 대폭 증가시키게 되므로 급수량이 많고 급수시간도 단축시킬 수 있으며 이로 인해 전기에너지의 절감과 효율을 높일 수 잇는 효과가 크다. As described above, in the present invention, when some of the plurality of water storage tanks (W) reach the full water level, the pressure applied thereto is added to the water supply pressure of the other water storage tanks (W) to greatly increase the water supply amount, so the water supply amount is large and the water supply time can be shortened. Therefore, the effect of saving electric energy and increasing efficiency is great.
