Description

{High and low pressure combined withdrawal coke}

The present invention relates to a high and low pressure combined water outlet cock that can be selectively used not only as a general low pressure type water outlet but also as a high pressure type water outlet cock. It relates to a high- and low-pressure water outlet cock that can be conveniently applied to both high-pressure and low-pressure applications by binding it to an appropriate pressure type to the drain faucet of a low-pressure water purifier.

Most of the conventional water outlet cocks were divided, but in the case of a high pressure faucet, which is a normal ball valve type that uses tap water with high water pressure, a metallic ball valve type outlet cock was used because of problems such as water leakage, and the water pressure was relatively low. In the case of the drain faucet of a low-pressure water purifier, it is common to use a water outlet cock with a built-in simple check valve.

Moreover, in recent years, as the water pressure of direct water purifiers is gradually increasing, the need for a high-pressure water outlet has been gradually emphasized. Until now, there is no outlet cock that can be used in both high and low pressures, and can also be used for high-temperature hot water. it can be said

Meanwhile, looking at the prior art related to the water outlet cock, which is a drain line of a water purifier or faucet, as described above, Korean Patent Publication No. 10-2015-0077976 (safety valve for hot water) or domestic utility model registration No. 20-0303626 (cold/hot water purifier) Drain cock), etc. have disclosed a technology capable of using a button-type valve and a lever-type valve at the same time while simplifying the structure of the cock valve or increasing the efficiency of lever operation.

In addition, through Korean Patent Publication No. 10-2012-0111880 (water outlet cock capable of switching multiple flow paths) or Korean Patent Publication No. 10-2013-0030586 (a valve device for simultaneous operation of inlet and outlet water of a water purifier), water pressure and A technology capable of simultaneously changing a plurality of flow paths and controlling the flow rate has been introduced regardless of the relationship. However, the technology of the high- and low-pressure water outlet cock, which can be used by selectively applying it to both the high-pressure faucet and the low-pressure water purifier drain faucet, has not been introduced.

Accordingly, the present invention intends to provide a high- and low-pressure water outlet cock that can be conveniently selected or mixed together as needed in response to high-pressure and low-pressure applications. That is, by binding the constituent means of the present invention as it is to the end of the low pressure water purifier drain pipe or the high pressure water pipe end, where the drain faucet (outlet water cock) is normally installed, it is conveniently used without being limited to low pressure and high pressure, or some of the overall constituent means Its purpose is to provide a new high-low pressure combined water outlet cock that can be structurally more reliably operated with the leak-blocking ability for the fluid by simply separating and removing the constituent means and binding it.

Hereinafter, it will be described in detail with reference to the drawings of the attached preferred embodiments of the principle of operation of the high and low pressure combined water outlet cock of the present invention.

Basically, the high and low pressure combined water outlet cock of the present invention can be naturally applied and used as a first water outlet cock for low pressure, and if necessary, a part of the constituent means without a separate high pressure outlet cock is attached to the housing body 10 to which the external pipe is bound. By inserting the pipe connection cap 11 inside, it is configured to be used simply and conveniently as a high-pressure outlet cock without any problem.

That is, as a configuration that can be used as a basic low-pressure water outlet cock, a general adjustment knob 50 for operating the opening (opening) and sealing (closing) of the cock as a lower external component is installed on the outer side of the housing body 10 ), the upper side is opened, and the pipe connection cap 11 connected to the end of the normal drain pipe or water pipe protrudes to the side, and the cock outlet 12 through which the fluid is discharged through the internal flow path protrudes from the bottom, the pipe The inner side of the connection cap 11 is screwed so that it can be screwed to the external pipe, and the cock outlet 12 is naturally narrowed toward the bottom of the housing body 10 .

And the vertical transfer actuator 20 positioned in the vertical direction inside the housing body 10 and operated in the longitudinal direction gradually expands the diameter for each section from the top to the bottom like a tower shape, and is sequentially sealed with the fastening protrusion 22 . The protrusion 23, the opening jaw part 24, and the sealing end 25 are respectively formed, and in particular, the sealing protrusion 23 is a horizontal transfer piece 35 of the horizontal transfer actuator 30 in the longitudinal direction when used for high pressure. It is configured to be in close contact with the high-pressure water outlet cock so that the high-pressure fluid does not flow into the space of the housing body 10 through the horizontal transfer actuator 30 at normal times.

And the vertical operation support 44 is configured so that the vertical transfer actuator 20 can be operated while being stably positioned in the inner space of the housing body 10, the vertical operation support 44 is the vertical transfer actuator ( 20), the upper fastening protrusion 22 passes through the center and is installed on the upper inner side of the housing body 10 so that it can be stably transported and the protrusion passing hole 43 penetrates to the center.

And the open upper side of the housing body 10 is closed with a separate upper body cap 40, the upper body cap 40 is located in the center so that the fastening protrusion 22 on the upper side of the vertical transfer actuator 20 passes. The protrusion through hole 41 is penetrated.

And the fastening protrusion 22 of the vertical transfer actuator 20 passing through the protrusion through hole 41 in the center of the upper body cap 40 is hinged so that the adjustment handle 50 is rotatably, the vertical transfer operation The upper end of the fastening protrusion 22 of the sieve 20 and the lower end of the adjustment handle 50 are each preferably penetrated with pin fastening holes 21 and 51 to be bound with a separate fixing pin 52 .

In particular, the vertical transfer actuator 20 applied in the present invention is opened when used by the adjustment handle 50, and the adjustment handle 50 and the vertical transfer actuator 20 are normally returned to their original positions so that the return operation can be performed. It is important that the return spring 42 is installed outside the fastening protrusion 22 of the vertical transfer actuator 20 .

On the other hand, so that the high and low pressure combined water outlet cock of the present invention can be used as a high pressure water outlet cock if necessary, there is additionally a minute inside the pipe connection cap 11 of the housing body 10 in the horizontal (length) direction. The horizontal transfer actuator 30 through which the flow path is penetrated is configured.

That is, the horizontal transfer actuator 30 is horizontally penetrated by a number of fine water inlet holes 31 so that one end positioned toward a conventional drain pipe or water pipe is enlarged and sealed so that a high-pressure fluid can be introduced into the penetrated interior. The transfer port 37 is configured.

And the other end of the horizontal transfer port 37 is screwed to each other while being screwed with each other so that the fluid introduced into the horizontal transfer port 37 through the water inlet hole 31 passes through the entire inside, so that the vertical transfer actuator A horizontal transfer piece (35) that is installed in close contact with the sealing protrusion (23) of (20) is configured.

And a horizontal operation support larger than the outer diameter of the horizontal transfer port 37 so that the horizontal transfer piece 35 and the integrally structured horizontal transfer port 37 can be stably transferred inside the pipe connection cap 1 ( 33) is constituted, the horizontal operation support 33 has a longitudinal direction through which the horizontal transfer port 37 is fastened to the center, and a return spring 34 is installed on the outside thereof in the longitudinal direction.

That is, the return spring 34 is a return spring 42 installed on the fastening protrusion 22 of the vertical transfer actuator 20 described above, and the durability of the housing body 10 when used by the adjustment handle 50 . When the space is opened, the closing protrusion 23 of the vertical transfer actuator 20 is in close contact as opposed to the return spring 42 being contracted while the vertical transfer actuator 20 is transferred upward. The return spring 34 of the horizontal transfer actuator 30, which has been positioned, is spaced apart from the closing protrusion 23 of the vertical transfer actuator 20 and moves to the lower opening jaw part 24, and naturally expands. is performed

On the contrary, when the normal adjustment knob 50 expands to the original position according to the restoring force of the return spring 42 of the vertical transfer actuator 20, naturally, the housing body 10 together with the original position return operation of the adjustment knob 50 Of course, the vertical transfer actuator 20 is also moved downward along with the expansion operation of the return spring 42 to return to its original position, and at the same time, it is positioned over the opening jaw part 24 of the vertical transfer actuator 20. As the horizontal transfer piece 35 of the horizontal transfer actuator 30 moves downward of the vertical transfer actuator 20 naturally, it moves toward the closing protrusion 23 of the vertical transfer actuator 20. Conversely, the return spring 33 of the transfer actuator 30 can also exhibit the principle of in-situ expansion operation, and of course, the discharge operation of the fluid through the internal flow path of the horizontal transfer actuator 20 can be stopped. .

In addition, the housing body 10 applied to the high and low pressure combined water outlet cock of the present invention has a contact surface as shown in the drawing to prevent leakage of the vertical transfer actuator 20 in the longitudinal direction and the horizontal transfer actuator 30 in the lateral direction. The constitutive relationship is formed by the principle that the sealing O-rings 32, 36, and 45 that are respectively fastened to the parts are properly installed and coupled. In particular, the bottom of the sealing end 25 of the vertical transfer actuator 20 is Naturally, the finish is inclined to correspond to the diameter of the cock outlet 12 .

The present invention of such a principle is for high pressure, the vertical transfer actuator 20 and the horizontal transfer actuator 30, which are configured to operate in opposite directions, are normally used when the vertical transfer actuator ( As 20) moves downward, the horizontal transfer actuator 30 is further moved toward the vertical transfer actuator 20 so that the closing protrusion 23 of the vertical transfer actuator 20 is securely positioned in close contact with the fluid flow. Provides a structure that blocks the path.

At this time, the bottom bottom surface of the vertical transfer actuator 20 is securely attached to the inside of the upper end of the cock outlet 12 of the housing body 10 to prevent water leakage, and at the same time, the horizontal transfer actuator 30 returns While moving toward the vertical transfer actuator 20 by the expansion force of the spring 34 , the water inlet hole 31 of the outer horizontal transfer port 37 of the horizontal transfer actuator 30 is naturally closed while the horizontal transfer The fluid flow (leakage) of the internal flow path of the actuator 30 is blocked. And when water is drawn out, the vertical transfer actuator 20 moves upward, and the horizontal transfer actuator 30 moves in the opposite direction (counterclockwise) of the vertical transfer actuator 20 so that the fluid flows along the fluid passage. The operating principle of water being discharged through the cock water outlet 12 is driven.

On the other hand, in the case of low pressure, only the vertical transfer actuator 20 inside the housing body 10 is simply configured without the configuration of the horizontal transfer actuator 30 in which the pipe connection cap 11 of the housing body 10 is located. When it is in a flat stop, the vertical transfer actuator 20 moves downward so that the lower sealed end 25 of the vertical transfer actuator 20 is inside the upper end of the cock outlet 12 of the housing body 10. It is closely adhered to prevent water leakage, and when water is used out, the vertical transfer actuator 20 moves upward due to the rotation operation of the adjustment handle 50 so that the inside of the housing body 10 becomes a fluid flow space, and the fluid The working principle of the outflow operation through the cock outlet 12 can be naturally exhibited.
