Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

In the following description, the same reference numerals will be used to refer to the same elements even though the same reference numerals are used to refer to the same elements.

1 to 5 show one embodiment of a filter assembly 1 (hereinafter referred to as a “filter assembly”) with an external valve lifting auto shutoff valve according to a preferred embodiment of the present invention.

As shown, the filter assembly 1 of the present invention includes a connector 100 connected to a pipe and fixedly installed, and a filter summ 200 detachably coupled to a lower portion of the connector 100.

The connector 100 is provided with an inlet 111 and an outlet 112 connected to the fluid supply pipe and the fluid discharge pipe, respectively, and an inlet passage 113 communicating with the inlet 111 and the outlet 112 at the lower side, respectively. And a coupler 120 having an outlet passage 114.

The inflow path 113 and the outflow path 114 are partitioned by a hollow guide tube 150 extending downward in a predetermined length in the inner central portion of the connector 100, as shown in Figs. The guide tube 150 extends vertically downward from the inlet 111 provided at one side of the connector 100 to guide the fluid introduced from the inlet 111 to be moved into the filter summ 200. It will play a role.

That is, the inner space of the coupler 120 is divided into two spaces by the guide tube 150, and the inside of the guide tube 150 is connected to the inlet 111. The outside of the guide tube 150 plays a role of the outlet passage 114 communicating with the outlet 112.

The guide tube 150 may be integrally formed as shown in the inside of the connector 100, but may be provided as a separate pipe member and assembled in the connector 100.

On the other hand, a valve for opening and closing the inflow passage 113 and the outflow passage 114 is installed inside the coupler 120.

In the filter assembly 1 according to the present invention, the valve may be provided to open and close only one of the inflow passage 113 and the outflow passage 114, similarly to a valve which is commonly used. For example, the inlet passage 113 and the outlet passage 114 are configured to simultaneously open and close the valve structure.

That is, the valve is inserted into the outer circumferential surface of the guide tube 150 made of a hollow formed through the fixing valve 130 and the central portion is fixed to the center of the connector 100, in detail installed in the center of the guide tube 150. It consists of an external valve 140 is installed.

The outer valve 140 is coupled to allow the sliding movement along the outer circumferential surface of the guide tube 150 is connected to each other in conjunction with the valve head 134 of the fixed valve 130 in accordance with the sliding movement the inflow path 113 And the outlet passage 114 is operated to open and close at the same time.

The fixed valve 130 is fixed so that one end is fixed to the inner central portion of the guide tube 150 and the other end is exposed to the outside of the open end (lower end) of the guide tube 150. That is, the support 132 having a predetermined length is fixedly installed such that one end is fixed to the upper side of the connector 100 and the other end provided with the valve head 134 is exposed to the lower end of the guide tube 150.

At this time, the valve head 134 is fastened to the support 132 so that a communication path 116 through which the fluid can move is disposed at a predetermined interval from the lower end of the guide tube 150. As a result, the outer valve 140 moves up and down along the guide tube 150 to block or open the communication path 116 to open and close the inflow path 113 connected to the communication path 116. .

More specifically, the upper end of the small diameter portion 232 and the lower end of the outer valve 140 are in close contact to prevent the inflow passage 113 and the outflow passage 114 from communicating with each other.

In addition, the valve head 134 is provided with a restraining portion 135 which is formed to be cut in a predetermined depth from the upper surface to the lower portion along the rim so as to limit the downward movement of the outer valve 140. ) Is separated from the guide tube 150 to prevent the separation. The restraining part 135 is formed at a position opposite to the end of the valve seat 122 of the coupler 120 so that the downward movement of the outer valve 140 when the filter summ 200 is separated is the restraining part 135. The outer peripheral surface of the outer valve 140 is limited by) to always keep in contact with the end of the valve seat 122 so that the outflow passage 114 can be stably blocked.

On the other hand, the outer side of the outer valve 140, the elastic member 142 is inserted and disposed so that the outer valve 140 is always received a force to move downward. That is, if no external force is applied to the external valve 140, the external valve 140 is moved downward to maintain the shut-off state at all times.

Accordingly, the connector 100 receives upward force by the head portion 230 of the filter summ 200 through the coupling with the filter summ 200, so that the outer valve 140 follows the guide tube 150. When moved upward, the close contact between the outer circumferential surface of the outer valve 140 and the end of the valve seat 122 is released to open the outlet passage 114 and at the same time, the communication path that is closed by the inner circumferential surface of the outer valve 140. As the 116 is opened, the inflow passage 113 is also opened, so that the inflow passage 113 and the outflow passage 114 are opened at the same time to achieve an open state of fluid flow in and out.

On the contrary, when the filter summ 200 is separated from the coupler 120, the external valve 140 is forced downward by the elastic member 142 so that the external valve 140 guides the guide tube 150. When moved downward and the downward movement of the outer valve 140 is limited by the restraining part 135, a part of the outer circumferential surface of the outer valve 140 is in close contact with the end of the valve seat 122 to open the outflow path 114. At the same time, the communication path 116 is sealed by the inner circumferential surface of the outer valve 140 so that the inflow path 113 also blocks the movement of the fluid so that the outflow path 114 and the inflow path 113 are simultaneously blocked. A blocking state is achieved.

On the other hand, a thread 124 is formed on the outer circumferential surface of the coupler 120 so that the filter summ 200 can be detachably coupled. Such a thread 124 is formed to correspond to the screw thread 124 formed at the end of the head portion 230-more specifically, the fastening portion 235 of the filter summ 200 to be described later, the filter sump through a simple screw coupling 200 to be fastened to the connector 100.

At this time, the coupler 120 is the inner diameter of the head portion 230 of the filter sump 200-more specifically, the diameter is approximately the same or smaller than the inner diameter of the large diameter portion 231 is provided with the coupler 120 ) Is inserted into the head 230 in a predetermined depth to be fastened.
