Abstract

The utility model relates to a water-supply valve for a water tank, which belongs to the water-supply valve of a water using and storing device of tall buildings. The utility model comprises the water tank, valve bodies and floats, wherein, the float A is connected with an upper water sealing valve arranged in the valve body A, and the valve body A is arranged in the water tank. The valve body B provided with the float B and a lower water sealing valve is connected with the valve body A, connects a tee and the valve body A together through a joint and then is connected with a water pipe. A check valve is arranged before a first switch behind a water meter, and the valve body A is provided with an upper water hole and a lower water hole. The utility model can solves the defects that water level is not easy to be controlled, the installation is inconvenient, the use is single, etc., which are existed in the existing water storing devices, can be automatically opened and closed and is suitable for being used in households of tall buildings.

Description

Water-supply valve for water tank

Water-supply valve for water tank belongs to the water supply valve in the high-rise building water water storage device.

China belongs to lack of water country, the northern area of China especially, in summer because the hydraulic pressure deficiency, water supply cuts in and out, the inconvenience of bringing live and work for the people that live in the highrise building, therefore some local Timing water supply of carrying out has just had water storage device---water tank.Now the water-storing tank on the market is made up of water tank, cursory and two water pipes of water-in and water-out mostly, this water tank is with cursory control water inlet water level, add two water pipes of water-in and water-out, complexity is installed, cost is higher, and can only be at the place water that water tank is installed, other room is water simultaneously, makes troubles to the user, also has cursory perishable, usually cause a large amount of current to lose, make the water resource serious waste.

The purpose of this utility model provides that a kind of water level is easy to control, simple installation, cost are low, a ground is installed many places and can be used at any time, and can open, close the Water-supply valve for water tank of avoiding current to lose automatically.

The purpose of this utility model is achieved in that

Water-supply valve for water tank, comprise water tank, valve body and cursory, wherein water floats A and is contained in the interior upper gas sealing valve of valve A and connects, valve A is contained in the water tank, the valve B that water floats B and following seal water valve is housed is connected on the valve A, threeway and valve A are connected together, link to each other with water pipe then by joint, flap valve is contained in behind the water meter before first switch, and last water hole and drainage hole are arranged on the valve A.

Because the utility model has adopted upper and lower water with same water pipe, installation work is easy greatly, realized ground installation water tank, many places make things convenient for water, adopt upper and lower seal water valve, control water level is reliable, open and close automatically, avoids current to lose, and cost reduces, and is suitable for general highrise building family and installs and uses.

Provide an embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Water-supply valve for water tank, comprise water tank, valve body and cursory, wherein water floats A1 and is contained in valve A 2 interior upper gas sealing valves 3 and connects, valve A 2 usefulness nuts add sealing mat and are contained in the water tank 12, the valve B 6 usefulness screw threads that water floats B7 and following seal water valve 5 are housed to be screwed on the valve A 2, by joint threeway and valve A 2 are connected together, link to each other with water pipe then, flap valve 10 is installed in behind the water meter before first switch by screwed joint.

When water pipe supplies water, in the water tank 12 when anhydrous, pressure is zero, at this moment each seal water valve is in shown position under action of gravity, at this moment water enters each seal water valve slit and last water hole 13 and drainage hole 14 by valve A 2 enter water tank 12 from water inlet, and promote water and float A1 and move up, after water tank 12 was full of water, water floated A1 and drives upper gas sealing valve 3 water gap is closed, pressure raises thereupon, water is floated promote to move upward under jacking seal water valve 5 and its slit shut of B7, thereby finished last water, the overall process of closing, when water inlet pipe is anhydrous, flap valve 10 moves down under the pressure of water tank water, and water inlet is oppositely shut, and has avoided the water in the water tank 12 to return.During water, no matter whether cut off the water, as long as open the taps of using in any one room, normal water just, if water inlet pipe has water, pressure is greater than the pressure of water in the water tank 12, flap valve 10 will be opened, and the water of water inlet pipe will flow into the place of water, and water tank water is motionless; Anhydrous as water inlet pipe, then water floats B7 and following seal water valve 5 and opens automatically, and the water in the water tank will flow into the place of water.

Claims

1. refrigerator water supply valve, comprise water tank, valve body and cursory, it is characterized in that: water floats A and is contained in the interior upper gas sealing valve of valve A and connects, valve A is contained in the water tank, the valve B that water floats B and following seal water valve is housed is connected on the valve A, threeway and valve A are connected together, link to each other with water pipe then by joint, flap valve is contained in behind the water meter before first switch, and last water hole and drainage hole are arranged on the valve A.
