Description

Floating ground for water {THE ANTIFREEZING WATERWORKS}

The present invention relates to an anti-freeze for water, and more particularly, to provide an improved anti-freeze to prevent freezing in winter by blocking supply of residual water into a water supply connected to the ground and connected to a water pipe buried underground.

In general, the floating water supply for water supply is connected to the water supply pipe buried underground and the water supply faucet located on the ground and the water supply pipe. It is to be drained to prevent the fear of freezing.

Looking at the configuration of the anti-freeze to which the prior art is applied to achieve the above object through Figure 6 as follows.

The floating field (1) to which the prior art is applied has a tubular floating field body (5) between the end of the water pipe (2) embedded in the ground and the lower end of the standing pipe (4) having a water supply (3) exposed to the ground. Connect.

Inside the floating body 5, a water passage 7 having a settling jaw 6 is formed, and the settling valve 7 of rubber material is seated on the settling 6 so as to maintain airtightness. .

The outer surface of the on-off valve (7) through the airtight material to prevent the floating body (5) and leakage phenomenon, the on-off valve (7) is connected to the handle (8) provided on the top of the riser pipe (4) It is fixed to the lower end of the opening and closing bar (9) to select the water flow and the number of steps by the rising or falling.

The dropping position upper riser tube 4 of the opening / closing valve 7 is formed by forming a drainage hole 10 for discharging the remaining constant in the riser tube 4 to the outside in a singular state.

In the prior art as described above, the water supply or the water supply is selected using a single valve, so there is no great difficulty in water supply, but there is a high possibility of freezing the granular pipe connected to the water supply because it cannot be completely watered in the water supply process. to be.

In other words, the on-off valve blocking the water flow hole formed in the floating body has excellent airtightness, but it is made of rubber material that is weak in abrasion resistance. Therefore, when the on-off valve is worn or damaged due to frequent use, the inlet pipe cannot be blocked. As a result, constant leakage occurs and the external air temperature decreases, which prevents freezing of the granular tube.

In addition, since the solenoid valve is made of only one and is made of rubber material that is vulnerable to freezing, it is difficult to block the water flow in the event of aging or damage of the on / off valve over time, thus achieving the fundamental purpose of preventing freezing of the winter standing pipe. It becomes difficult to do.

As such, the quality and lifespan of the floating valve is reduced due to the weak durability of the switching valve for water and water, and the replacement cycle is shortened due to the damage of the switching valve. Problems are occurring.

Therefore, the present invention is invented to solve the problems as described above is connected between the end of the water pipe buried in the ground and the bottom of the granular pipe having a water hydrant exposed to the ground to select the number of water supply and the number of water supply to the hydrant and in winter In a water-free anti-freeze system which drains a constant inside a granular tube to prevent freezing;

The anti-freeze is an upper and lower floating front body provided in a tubular shape by projecting a connector for connecting the riser pipe and the water pipe on the upper and lower sides, and the upper and lower sides of the annulus having a connection hole in the center in the inner center of the floating electric body A fitting formed with an inclined surface, a lower valve and an upper valve provided on the lower side and the upper side of the fitting, and the lower valve is singulated by water pressure, and the upper valve is opened and closed by an opening bar connected to a handle of an upper end of a standing pipe. By selecting the water flow and water flow, the lower valve can be switched to the water flow state by the upper valve during water flow, thereby achieving the purpose of improving the quality and durability of the anti-freeze while preventing leakage by increasing airtightness during water flow.

The present invention uses a material that has excellent corrosion and durability, such as stainless steel, copper, ceramic, while constituting a pair of shut-off valves constituting a floating power to prevent damage or abrasion even in long-term use to facilitate water and water It is an invention having various effects, such as improving the quality and durability of the anti-freeze while achieving the purpose of freezing, to increase external competitiveness.

Hereinafter, with reference to the accompanying drawings will be described a preferred configuration and operation of the present invention for achieving the above object.

The conventional water supply station 100 is connected between the end of the water pipe 101 buried in the ground and the lower end of the standing pipe 103 having the water supply 102 exposed to the ground to pass water and water to the water supply 102. In addition to selecting the winter in order to prevent the freeze by draining the water inside the standing tube (103).

In the present invention, it is characterized in that to achieve the object of freezing prevention by improving the durability and airtightness while improving the anti-freeze (100) to facilitate the water and water.

Floating field 100 to which the technique of the present invention is applied for this purpose, the tubular floating field body 106 which protrudes the connector 105 for connecting the granular pipe 103 and the water pipe 101 to the upper and lower sides thereof. It is provided, and in the inner center of the floating body 106 is formed a fitting port 110, the inclined surface 109 is formed on the upper and lower sides of the annulus 108 having a connecting hole 107 in the center of the shaft.

The lower valve 111 and the upper valve 112 are connected to the lower side and the upper side through the lower valve 111 and the upper valve 112 by water pressure, and the upper valve 112 is the riser pipe 103. While the water supply and the water is selected by the opening and closing bar (R) connected to the handle (H) of the upper end, the lower valve 111 is also switched to the water supply state by the upper valve 112 at the time of water supply.

The lower and upper valves 111 and 112 include lower and upper valve bodies 115 and 116 of annular bodies having inclined surfaces and rounds 113 and 114 so as to engage with the inclined surfaces 109 of the fitting holes 110 to maintain airtightness. The lower and upper valve bodies 115 and 116 radially form a plurality of water passages 117 and 118 for water passage.

The upper outer surface of the upper valve 112 is formed in a multi-layered airtight groove 119 through the airtight member 120, such as O-ring to maintain the airtight with the floating body 106 to prevent leakage, the upper valve The inner surface of the 112 is connected to the opening and closing bar (R) to combine the operating rod 121 for moving the upper valve 112 up and down to select the number of water and the number of stages.

The lower end of the operation rod 121 is coupled to the operation groove 123 formed on the upper surface of the lower valve 111 by protruding the interlocking pins 122 is pressed down by the interlocking pins 122 to open the water flow. Make it open.

The actuating rod 121 positioned in the upper valve 112 forms a screw cap 125 having a screw formed in a direction opposite to the rotation direction of the opening / closing bar R so that the opening and closing bar R is rotated forward. 125 is the reverse rotation, the opening and closing bar (R) is configured to be elevated while the screw cap 125 is reverse rotation while the reverse rotation.

Looking at the operating state of the water supply for power 100 is applied as described above as follows.

When the initial state is viewed in the singular state, the lower valve 111 is in a free state without being restrained by the interlocking pin 122 protruding from the lower end of the operating rod 121 coupled with the upper valve 112. 111 is raised by the water pressure, and the inclined surface 113 of the lower valve body 115 and the inclined surface 109 formed in the fitting hole 110 of the floating body 106 are intimately connected, so that the constant is constant. Moving upward through the connection hole 107 is blocked.

In this state, the round 114 of the upper valve 112 also makes a close contact with the inclined surface 109 of the fitting hole 110 to prevent the constant from rising through the connection hole 107, thus preventing double blocking. Will be

The upper valve 112 can be in close contact with the fitting port 110 is the handle (H) provided in the upper part of the riser tube 103 in a reverse direction (locking direction) is connected to the opening and closing bar (R) To rotate the operating rod 121 of the upper valve 112.

Then, the actuating rod 121 forms a half-screw on the actuating rod 121 while rotating in reverse, thereby moving the combined screw cap 125 and the upper valve body 116 in the forward direction (downward direction), so that the upper valve body ( 116 is lowered so that the round 114 of the upper valve 112 and the inclined surface of the fitting port 110 is connected.

In addition, since the interlocking pins 122 protruding from the lower end of the actuating rod 121 are raised while the actuating rod 121 rotates in the reverse direction, the force held by the lower valve 111 disappears, so that the lower valve 111 is naturally Ascending by hydraulic pressure, the inclined surface 109 and the inclined surface 113 of the fitting sphere 110 are connected to perform the singular.

In addition, as the upper valve 112 descends, the airtight member 120 positioned at the top of the outer surface of the upper valve 112 moves to a position lower than the discharge hole 130 formed in the floating body 106. The remaining water inside the inside is discharged to the ground through the discharge hole 130 to prevent freezing even if the outside air temperature is low.

In this state, if you want to switch to the water-permeable state, by rotating the handle (H) in the forward direction, the screw cap 125 coupled to the descending operating rod 121 is rotated while rotating the upper valve 112 in the reverse direction Moving upwards of the coin body 106 is spaced apart from the fitting sphere 110, the interlocking pin 122 protruding from the lower end of the actuating rod 121 is the operating groove formed on the upper surface of the lower valve 111 ( It is inserted into the 123 to push the lower valve 111 down.

Therefore, since the lower valve 111 is also spaced apart from the fitting hole 110, the constant is interposed between the gap between the lower valve 1110 and the floating body body 106 and the through hole 117 formed in the lower valve 111. It is conveyed upward through the connection hole 107 of the 110.

Since the constant conveyed to the upper side is blocked by the anti-floating body 106 by the airtight member 120, and then moved in the direction of the operating rod 121 through the through hole 118 radially formed on the upper valve 112. Since it is supplied to the granular pipe 103, it is possible to discharge the constant through the water supply 102.

In the present invention, the lower and upper valves 111 and 112 provided at the top and the bottom when water are kept close to close the supply of water by maintaining airtightness, and when passing the water, the lower and upper valves 111 and 112 are spaced apart from each other. It is an invention having various advantages such that opening and closing operations are performed by a pair of valves, thereby providing airtightness and improving water quality and durability while providing water and ease of water flow.
