종래의 온수개폐밸브는, 이들 도면에 도시된 바와 같이, 일 측이 개구되도록 형성된 밸브몸체(110)와, 밸브몸체(110)의 개구를 통해 밸브몸체(110)의 내부에 설치되는 밸브체(140)를 구비한 카트리지(130)와, 밸브체(140)의 이동을 조작하기 위한 개폐조작부(150)를 갖고 있다.Conventional hot water opening and closing valve, as shown in these figures, the valve body 110 is formed so that one side is opened, and the valve body which is installed inside the valve body 110 through the opening of the valve body 110 ( A cartridge 130 having a 140 and an opening and closing operation unit 150 for manipulating the movement of the valve body 140 are provided.

밸브몸체(110)는 직선상의 유로관부(111)와, 유로관부(111)로부터 분기 형성된 이동안내관부(115)를 갖고 있다.The valve body 110 has a straight flow path tube part 111 and a movement guide tube part branched from the flow path tube part 111.

유로관부(111)는 내부에 입수측과 출수측으로 구획하는 밸브시트(111b)가 형성되어 있다.The flow path pipe part 111 is formed with a valve seat 111b partitioned into an inlet side and an outlet side.

이동안내관부(115)는 유로관부(111)에 대하여 경사를 이루도록 형성되어 있고, 종단영역 내주면에는 암나사부가 형성되어 있다.The movement guide tube part 115 is formed to be inclined with respect to the flow path tube part 111, and the female screw part is formed in the inner peripheral surface of the terminal area.

카트리지(130)는 밸브체(140)에 더하여 이동안내관부(115)에 그 외표면이 밀착되도록 장착되는 개폐안내관(135)과, 개폐안내관(135)에 장착되는 비감응스프링(134)과, 개폐안내관(135)의 전방에서 밸브체(140)에 장착되는 감응스프링(131)과, 개폐안내관(111)의 외표면 중앙영역에 장착되는 밀폐링(181)을 갖고 있다.The cartridge 130 is in addition to the valve body 140, the opening and closing guide tube 135 is mounted so that the outer surface is in close contact with the movement guide tube section 115, and the non-sensitive spring 134 mounted to the opening and closing guide tube 135 And a sensitive spring 131 mounted to the valve body 140 in front of the opening / closing guide tube 135 and a sealing ring 181 mounted to an outer surface central region of the opening / closing guide tube 111.

개폐안내관(135)은 전면 둘레연부에 지지턱(135a)이 내측을 향해 형성되고, 후단영역 내주면에 암나사부가 형성되어 있다.The opening and closing guide tube 135 has a supporting jaw 135a formed at an inner circumferential edge of the opening and closing guide tube 135, and a female screw portion is formed at an inner circumferential surface of the rear end region.

이러한 구성을 갖는 개폐안내관(135)은 지지턱(135a)이 밸브시트(111b)를 향하도록 이동안내관부(115)의 내부에 설치되어 있다.The opening and closing guide tube 135 having such a configuration is installed inside the movement guide tube section 115 so that the support jaw 135a faces the valve seat 111b.

밸브체(140)는 밸브시트(111b)에 형상 맞춤되도록 형성된 밸브체헤드부(141)와, 밸브체헤드부(141)로부터 연장 형성된 봉상의 밸브체다리부(142)와, 밸브체다리부(142)의 자유단에 나사결합된 지지판(143)을 갖고 있다.The valve body 140 includes a valve body head portion 141 formed to conform to the valve seat 111b, a rod-shaped valve body portion 142 extending from the valve body head 141, and a valve body portion. It has a support plate 143 screwed to the free end of 142.

밸브체헤드부(141)는 곡면영역이 밸브시트(111b)를 향하도록 반구형으로 형성되어 있다.The valve body head portion 141 is formed in a hemispherical shape such that the curved region faces the valve seat 111b.

이러한 구성을 갖는 밸브체(140)는 밸브체헤드부(141)가 밸브시트(111b)를 향하고 밸브체다리부(142)가 개폐안내관(135)의 전면개구를 관통하도록 이동안내관부(115)에 장착되어 있다.In the valve body 140 having such a configuration, the movement guide pipe part 115 may allow the valve body head 141 to face the valve seat 111b and the valve body part 142 to penetrate the front opening of the opening and closing guide pipe 135. )

비감응스프링(134)은 지지판(143)과 지지턱(135a)사이에 개재하도록 개폐안내관(135)의 내부에 장착된다.The non-sensitive spring 134 is mounted inside the opening and closing guide tube 135 so as to be interposed between the supporting plate 143 and the supporting jaw 135a.

감응스프링(131)은 일방향성 형상기억합금재질로 제작된다. 이에 따라 감응스프링(131)은 특정의 형상회복온도이하에서 제작시 외력에 의해 변형되어도 특정의 형상회복온도이상이 되면 기억된 형상으로 복원하게 된다. 여기서 감응스프링(131)은 차단시키고자하는 온수의 상한온도를 고려하여 형상회복온도를 결정한다. 예를 들면 차단시키고자 하는 온수의 상한온도가 섭씨 50도인 경우 섭씨 50도의 형상회복온도를 갖도록 성분비를 조절하여 감응스프링(131)을 제작할 수 있다.The sensitive spring 131 is made of a unidirectional shape memory alloy material. Accordingly, the sensitized spring 131 is restored to the stored shape if the specific shape recovery temperature is higher than the specific shape recovery temperature even if it is deformed by an external force at the time of manufacturing below the specific shape recovery temperature. Here, the sensitive spring 131 determines the shape recovery temperature in consideration of the upper limit temperature of the hot water to be blocked. For example, when the upper limit temperature of the hot water to be blocked is 50 degrees Celsius, the sensitive spring 131 may be manufactured by adjusting the component ratio to have a shape recovery temperature of 50 degrees Celsius.

그리고 감응스프링(131)은 마르텐사이트상에서의 탄성계수가 비감응스프링(134)의 탄성계수보다 큰 값을 갖도록 형성되어 있다. 이에 따라 감응스프링(131)은 형상회복온도이상에서 비감응스프링(134)의 탄성력을 극복하고 기억된 형상으로 복원즉, 신장할 수 있게 된다.The sensitive spring 131 is formed such that the elastic modulus on the martensite has a value larger than that of the non-sensitized spring 134. Accordingly, the sensitive spring 131 overcomes the elastic force of the non-sensitive spring 134 at a shape recovery temperature or higher, and restores it to a stored shape, that is, extends.

밀폐링(181)은 이동안내관부(115)의 내벽면에 형성된 고리상의 홈에 장착되어 있다.The sealing ring 181 is mounted in a ring-shaped groove formed on the inner wall surface of the movement guide tube 115.

개폐조작부(150)는 이동안내관부(115)에 장착되는 가압블럭(151)과, 가압블럭(151)의 블럭다리부(151c)에 결합된 대략 디귿자 형상 단면의 핸들(152)을 갖고 있다.The opening / closing operation unit 150 has a pressure block 151 mounted on the movement guide tube unit 115 and a handle 152 having a substantially dichroic cross section coupled to the block leg portion 151c of the pressure block 151.

가압블럭(151)은 블럭어깨부(151b)와, 블럭어깨부(151b)보다 작은 직경을 갖도록 블럭어깨부(151b)의 전면으로부터 연장 형성된 블럭헤드부(151a)와, 블럭어깨부(151b)의 후면으로부터 블럭헤드부(151a)와 반대방향으로 연장 형성된 블럭다리부(151c)를 갖고 있다.The pressure block 151 includes a block shoulder portion 151b, a block head portion 151a extending from the front surface of the block shoulder portion 151b to have a diameter smaller than that of the block shoulder portion 151b, and a block shoulder portion 151b. And a block leg portion 151c extending in a direction opposite to the block head portion 151a.

블럭어깨부(151b)는 외주면에 후방수나사부가 형성되어 있다.The block shoulder portion 151b has a rear male screw portion formed on an outer circumferential surface thereof.

블럭헤드부(151a)는 외주면에 개폐안내관(135)의 암나사부와 상호 작용하는 전방수나사부가 형성되어 있다.The block head portion 151a has a front male thread portion formed on the outer circumference thereof to interact with the female thread portion of the opening and closing guide tube 135.

이러한 구성을 갖는 가압블럭(151)은 후방수나사부가 이동안내관부(115)의 암나사부에 맞물리리고 전방수나사부가 개폐안내관(135)의 암나사부에 맞물리도록 이동안내관부(115)에 장착되어 있다.The pressure block 151 having such a configuration is mounted to the movement guide tube section 115 so that the rear male thread portion engages the female thread portion of the movement guide tube section 115 and the front male thread portion engages the female thread portion of the opening and closing guide tube 135. have.

전술한 구성을 갖는 종래 온수개폐밸브의 동작을 도13, 도16 및 도17을 참조하여 설명하면 다음과 같다. 설명의 편의를 위해 밸브시트(111b)는 개방되어 있는 것으로 가정한다. 이와 같이 밸브시트(111b)가 개방된 상태에서 비감응스프링(134)과 감응스프링(131)은 제작시의 형상 그대로를 유지하고 있다. 그리고 유로관부(111)의 상단(출수측)이 온수가열원(보일러 등)에 연결되어 있는 것(환수 유로상에 온수개폐밸브가 설치됨)으로 가정한다.Referring to Figures 13, 16 and 17 the operation of the conventional hot water opening and closing valve having the above-described configuration as follows. For convenience of explanation, it is assumed that the valve seat 111b is open. In this way, the non-sensitized spring 134 and the sensitized spring 131 maintain the shape at the time of manufacture in the state in which the valve seat 111b was opened. And it is assumed that the upper end (outflow side) of the flow path pipe part 111 is connected to the hot water heating source (boiler, etc.) (the hot water opening and closing valve is installed on the return flow path).

먼저 핸들(152)이 하강하도록 회전조작하면, 가압블럭(151)은 밸브시트(111b)에 접근하는 방향으로 이동한다.First, when the handle 152 is rotated to descend, the pressure block 151 moves in the direction approaching the valve seat 111b.

가압블럭(151)이 밸브시트(111b)에 접근하는 방향으로 이동함에 따라 밸브체(140)는 밸브시트(111b)에 접근하고 밸브시트(111b)는 폐쇄된다(도16 참조).As the pressure block 151 moves in the direction approaching the valve seat 111b, the valve body 140 approaches the valve seat 111b and the valve seat 111b is closed (see Fig. 16).

다음에 핸들(152)이 상승하도록 회전조작하면, 가압블럭(151)은 밸브시트(111b)로부터 멀어지는 방향으로 이동한다.Next, when the handle 152 is rotated so as to ascend, the pressing block 151 moves in a direction away from the valve seat 111b.

가압블럭(151)이 밸브시트(111b)로부터 멀어지는 방향으로 이동함에 따라 밸브체(140)는 밸브시트(111b)로부터 멀어지고 밸브시트(111b)는 개방된다(도13 참조).As the pressure block 151 moves away from the valve seat 111b, the valve body 140 moves away from the valve seat 111b and the valve seat 111b opens (see Fig. 13).

밸브시트(111b)가 개방되면 온수는 입수측으로부터 유입되어 밸브시트(111b)를 통과한 후, 출수측으로 유출된다.When the valve seat 111b is opened, hot water flows in from the inlet side and passes through the valve seat 111b, and then flows out of the outlet side.

밸브시트(111b)가 개방된 상태에서 내부유로를 통해 흐르는 온수로부터 감응스프링(131)에 열이 전달된다.Heat is transferred from the hot water flowing through the internal flow passage to the sensitive spring 131 in a state where the valve seat 111b is opened.

내부유로를 통해 흐르는 온수의 온도가 형상회복온도까지 상승하면, 감응스프링(131)은 신장(기억된 형상임)된다.When the temperature of the hot water flowing through the internal passage rises to the shape recovery temperature, the sensitive spring 131 is elongated (memorized shape).

감응스프링(131)이 신장함에 따라 밸브체(140)는 밸브시트(111b)를 향해 하강하고 밸브시트(111b)는 폐쇄된다(도17 참조). 밸브체(140)가 하강하는 동안 비감응스프링(134)은 수축된다.As the sensitive spring 131 extends, the valve body 140 descends toward the valve seat 111b and the valve seat 111b is closed (see Fig. 17). The non-sensitive spring 134 is contracted while the valve body 140 is lowered.

밸브시트(111b)가 폐쇄되면 제어부(도시되지 않음)는 온수가열원(도시되지 않음)과 순환펌프(도시되지 않음)의 동작이 일시적으로 중지되도록 제어한다. 온수가열원(도시되지 않음)과 순환펌프(도시되지 않음)의 동작이 중지되면 내부유로 내의 온수의 온도는 하강한다.When the valve seat 111b is closed, the controller (not shown) controls the operation of the hot water heating source (not shown) and the circulation pump (not shown) to be temporarily stopped. When the operation of the hot water heating source (not shown) and the circulation pump (not shown) are stopped, the temperature of the hot water in the inner flow passage decreases.

내부유로 내의 온수의 온도가 하강함에 따라, 감응스프링(131)은 원래의 형상으로 복귀한다.As the temperature of the warm water in the inner flow passage decreases, the sensitive spring 131 returns to its original shape.

감응스프링(131)이 원래의 형상으로 복귀하면 비감응스프링(134)의 탄성력에 의해 밸브체(140)는 밸브시트(111b)로부터 상승하고, 밸브시트(111b)는 다시 개방된다.When the sensitive spring 131 returns to its original shape, the valve body 140 is raised from the valve seat 111b by the elastic force of the non-sensitive spring 134, and the valve seat 111b is opened again.

밸브시트(111b)가 개방되면, 제어부(도시되지 않음)는 온수가열원(도시되지 않음)과 순환펌프(도시되지 않음)의 동작을 재개시킨다.When the valve seat 111b is opened, the controller (not shown) resumes the operation of the hot water heating source (not shown) and the circulation pump (not shown).

온수가열원(도시되지 않음)과 순환펌프(도시되지 않음)의 동작이 재개되면, 온수는 입수측으로부터 유입되어 밸브시트(111b)를 통과한 후 출수측을 통해 다시 유출된다.When the operation of the hot water heating source (not shown) and the circulation pump (not shown) are resumed, the hot water flows in from the inlet side, passes through the valve seat 111b, and then flows out again through the outlet side.

전술한 구성을 갖는 종래의 온수개폐밸브는 2005년 특허출원 제5489호(발명의 명칭 : 온수개폐밸브용 카트리지)에 개시되어 있다.A conventional hot water open / close valve having the above-described configuration is disclosed in 2005 Patent Application No. 5489 (Inventive Name: Cartridge for Hot Water Open / Close Valve).

그런데 종래의 온수개폐밸브에 따르면, 밸브체헤드부(141)가 감응스프링(131)의 전방에 배치되어 있기 때문에 밸브체헤드부(141)에 의해 밸브시트(111b)가 폐쇄된 상태에서 밸브체헤드부(141)에 의해 입수측(유로관부의 하단)과 감응스프링(131)이 차단된다. 이에 따라 밸브체헤드부(141)에 의해 밸브시트(111b)가 폐쇄된 상태에서 감응스프링(131)의 감응동작이 늦어진다(입수측온수 온도가 내려갈 때 밸브시트가 개방되는 속도가 늦어짐)는 문제점이 있었다.By the way, according to the conventional hot water opening and closing valve, since the valve body head 141 is disposed in front of the sensitive spring 131, the valve body in the state in which the valve seat 111b is closed by the valve body head 141 The inlet side (lower end of the flow pipe section) and the sensitive spring 131 are blocked by the head portion 141. Accordingly, in response to the valve seat 111b being closed by the valve body head 141, the sensitive operation of the sensitive spring 131 is slowed down (the speed at which the valve seat opens when the inlet-side water temperature decreases) becomes slow. There was this.

그리고 밸브체헤드부(141)가 감응스프링(131)의 전방에 배치되어 있기 때문에 밸브시트(111b)가 개방된 상태에서 감응스프링(131)의 감응영역이 작아진다. 이에 따라 밸브시트(111b)가 개방된 상태에서 감응스프링(131)의 감응동작이 늦어진다(입수측온수 온도가 올라갈 때 밸브시트가 폐쇄되는 속도가 늦어짐)는 문제점이 있었다.And since the valve body head part 141 is arrange | positioned in front of the sensitive spring 131, the sensitive area of the sensitive spring 131 becomes small in the state which valve seat 111b is open. Accordingly, there is a problem in that the action of the sensitive spring 131 becomes slow in the state in which the valve seat 111b is opened (the speed at which the valve seat is closed when the inlet-side hot water temperature rises) becomes slow.

전술한 구성을 갖는 본 발명의 실시예에 따른 온수개폐밸브의 동작을 도2 및 도10 내지 도12를 참조하여 설명하면 다음과 같다. 설명의 편의를 위해 밸브시트(11b)는 개방되어 있는 것으로 가정한다. 이와 같이 밸브시트(11b)가 개방된 상태에서 비감응스프링(34)과 감응스프링(31)은 제작시의 형상 그대로를 유지하고 있다. 그리고 입수관부(15)가 온수가열원(보일러 등)에 연결되어 있는 것(환수 유로상에 온수개폐밸브가 설치됨)으로 가정한다. Referring to Figures 2 and 10 to 12 the operation of the hot water opening and closing valve according to an embodiment of the present invention having the above-described configuration as follows. For convenience of explanation, it is assumed that the valve seat 11b is open. In this way, the non-sensitized spring 34 and the sensitive spring 31 maintain the shape at the time of manufacture in the state in which the valve seat 11b was opened. And it is assumed that the water inlet pipe 15 is connected to a hot water heating source (boiler, etc.) (the hot water opening and closing valve is installed on the return flow path).

먼저 핸들(52)이 밸브시트(11b)에 접근하도록 회전조작하면, 가압블럭(51)은 밸브시트(11b)에 접근하는 방향으로 이동한다.First, when the handle 52 rotates to approach the valve seat 11b, the pressure block 51 moves in the direction approaching the valve seat 11b.

가압블럭(51)이 밸브시트(11b)에 접근하는 방향으로 이동함에 따라 밸브체(40)는 밸브시트(11b)에 접근하여 폐쇄위치에 도달하고 밸브시트(11b)는 폐쇄된다(도10 참조). 가압블럭(51)이 밸브시트(11b)에 접근하는 동안 조작복귀스프링(54)에는 탄성력이 축적된다.As the pressure block 51 moves in the direction approaching the valve seat 11b, the valve body 40 approaches the valve seat 11b to reach the closed position and the valve seat 11b is closed (see Fig. 10). ). An elastic force is accumulated in the operation return spring 54 while the pressure block 51 approaches the valve seat 11b.

다음에 핸들(52)이 밸브시트(11b)로부터 멀어지도록 회전조작하면, 조작복귀스프링(54)에 축적된 탄성력에 의해 가압블럭(51), 밸브체지지관(32) 및 밸브체(40)는 밸브시트(11b)로부터 멀어지는 방향으로 이동한다. 여기서 밸브체(40)의 이동은 비감응스프링(34)과 밸브체작동축(33)의 도움을 받아 이루어진다.Next, when the handle 52 is rotated away from the valve seat 11b, the pressure block 51, the valve body support tube 32, and the valve body 40 are driven by the elastic force accumulated in the operation return spring 54. It moves in the direction away from the valve seat 11b. Here, the movement of the valve body 40 is made with the help of the non-sensitive spring 34 and the valve body operating shaft 33.

가압블럭(51)이 밸브시트(11b)로부터 멀어지는 방향으로 이동함에 따라 밸브체(40)는 밸브시트(11b)로부터 멀어져 개방위치에 도달하고 밸브시트(11b)는 개방된다(도2 참조).As the pressure block 51 moves in a direction away from the valve seat 11b, the valve body 40 moves away from the valve seat 11b to reach an open position and the valve seat 11b is opened (see Fig. 2).

밸브시트(11b)가 개방되면 온수는 입수관부(15)로부터 유입되어 밸브시트(11b)를 통과한 후, 입수관부(15)를 통해 유출된다.When the valve seat 11b is opened, hot water flows in from the inlet pipe part 15 and passes through the valve seat 11b, and then flows out through the inlet pipe part 15.

밸브시트(11b)가 개방된 상태에서 내부유로를 통해 흐르는 온수로부터 감응스프링(31)에 열이 전달된다.Heat is transferred from the hot water flowing through the internal flow passage to the sensitive spring 31 in the state where the valve seat 11b is opened.

내부유로를 통해 흐르는 온수의 온도가 형상회복온도까지 상승하면, 감응스프링(31)은 신장(기억된 형상임)된다.When the temperature of the hot water flowing through the internal flow path rises to the shape recovery temperature, the sensitive spring 31 is elongated (memorized shape).

감응스프링(31)이 신장함에 따라 밸브체(40)는 밸브시트(11b)를 향해 전진하여 폐쇄위치에 도달하고 밸브시트(11b)는 폐쇄된다(도11 참조). 밸브체(40)가 전진하는 동안 비감응스프링(34)은 수축된다.As the sensitive spring 31 extends, the valve body 40 advances toward the valve seat 11b to reach the closed position, and the valve seat 11b is closed (see Fig. 11). The non-sensitive spring 34 is retracted while the valve body 40 is advanced.

밸브시트(11b)가 폐쇄되면 제어부(도시되지 않음)는 온수가열원(도시되지 않음)과 순환펌프(도시되지 않음)의 동작이 일시적으로 중지되도록 제어한다. 온수가열원(도시되지 않음)과 순환펌프(도시되지 않음)의 동작이 중지되면 내부유로 내의 온수의 온도는 하강한다.When the valve seat 11b is closed, the controller (not shown) controls the operation of the hot water heating source (not shown) and the circulation pump (not shown) to be temporarily stopped. When the operation of the hot water heating source (not shown) and the circulation pump (not shown) are stopped, the temperature of the hot water in the inner flow passage decreases.

내부유로내의 온수의 온도가 하강함에 따라, 감응스프링(31)은 원래의 형상으로 복귀한다.As the temperature of the warm water in the inner flow passage decreases, the sensitive spring 31 returns to its original shape.

감응스프링(31)이 원래의 형상으로 복귀하면 비감응스프링(34)의 탄성력에 의해 밸브체(40)는 밸브시트(11b)로부터 멀어지고, 밸브시트(11b)는 다시 개방된다.When the sensitive spring 31 returns to its original shape, the valve body 40 is separated from the valve seat 11b by the elastic force of the non-sensitive spring 34, and the valve seat 11b is opened again.

밸브시트(11b)가 개방되면, 제어부(도시되지 않음)는 온수가열원(도시되지 않음)과 순환펌프(도시되지 않음)의 동작을 재개시킨다.When the valve seat 11b is opened, the control unit (not shown) resumes operation of the hot water heating source (not shown) and the circulation pump (not shown).

온수가열원(도시되지 않음)과 순환펌프(도시되지 않음)의 동작이 재개되면, 온수는 입수관부(15)로부터 유입되어 밸브시트(11b)를 통과한 후 출수관부(16)를 통해 다시 유출된다.When the operation of the hot water heating source (not shown) and the circulation pump (not shown) are resumed, the hot water flows in from the inlet pipe part 15 and passes through the valve seat 11b, and then again flows out through the outlet pipe part 16. do.

한편 밸브시트(11b)의 개방도는 핸들(52)을 회전조작하여 선택할 수 있다(도12 참조).On the other hand, the opening degree of the valve seat 11b can be selected by rotating the handle 52 (see Fig. 12).

전술한 실시예에서는 개폐조작부로서 핸들(60)을 채용하고 있으나, 정역회전할 수 있는 모터 등을 개폐조작부로서 채용하여 본 발명을 적용할 수 있다.In the above-described embodiment, the handle 60 is employed as the opening and closing operation unit, but the present invention can be applied by employing a motor capable of forward and reverse rotation as the opening and closing operation unit.

상술한 바와 같이 본 발명의 실시예에 따르면, 감응스프링(31)이 밸브체(40)의 내부에 장착되고 밸브체(40)의 측면이 밸브시트에 접촉하고 분리되는 동작에 따라 밸브시트가 개폐되도록 함으로써, 밸브시트(11b)가 폐쇄된 상태에서 감응스프링(31)이 입수관부(15) 내의 온수에 충분히 감응할 수 있게 된다. 이에 따라 밸브시트(11b)가 폐쇄된 상태에서 감응스프링(31)의 감응동작이 개선된다.According to the embodiment of the present invention as described above, the valve seat is opened and closed in accordance with the action that the sensitive spring 31 is mounted inside the valve body 40 and the side of the valve body 40 is in contact with and separated from the valve seat. By doing so, in response to the valve seat 11b being closed, the sensitive spring 31 can be sufficiently sensitive to hot water in the water inlet pipe 15. This improves the sensitive operation of the sensitive spring 31 in the state where the valve seat 11b is closed.

그리고 감응스프링(31)이 밸브체(40)의 내부에 장착되고 밸브체(40)의 측면이 밸브시트에 접촉하고 분리되는 동작에 따라 밸브시트가 개폐되도록 함으로써, 밸브시트(11b)가 개방된 상태에서 감응스프링(31)이 입수관부(15) 내의 온수와 출수관부(16) 내의 온수에 감응할 수 있게 된다. 이에 따라 밸브시트(11b)가 개방된 상태에서 감응스프링(31)의 감응동작이 개선된다.In addition, the valve seat 11b is opened by allowing the valve seat 11 to be opened and closed in response to the operation of the inductive spring 31 mounted inside the valve body 40 and the side surface of the valve body 40 contacting and detaching the valve seat. In the state, the sensitive spring 31 can be sensitive to hot water in the inlet pipe unit 15 and hot water in the outlet pipe unit 16. This improves the sensitive operation of the sensitive spring 31 in the state where the valve seat 11b is opened.

또한 감응스프링(31)이 입수관부(15)와 출수관부(16)에 대하여 수직으로 배치되어 있기 때문에 밸브몸체(10)의 길이구간이 감소된다.In addition, since the sensitive spring 31 is disposed perpendicularly to the water inlet pipe 15 and the water outlet pipe 16, the length section of the valve body 10 is reduced.
