Description
Technical Field
The utility model relates to an industry water supply and drainage system, especially a valve that can close by oneself.
Background
Among the industry water supply and drainage system, the valve is a common key equipment that cuts off energy medium and carry, and the valve in some water supply and drainage pipes needs manual work or other auxiliary device to realize the switch, needs people's manual switch of opening during the feedwater, if forget and close the valve, more can cause the waste of water resource during the feedwater, and the valve forgets to close, and the pipeline is not sealed, and harmful gas leaks easily and causes danger.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that needs to solve provides a valve that can close by oneself, can realize the automatic switching of valve according to whether there is water in the pipeline.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
the utility model provides a valve that can close by oneself, includes the valve body, the valve body top is provided with inlet tube, the below is provided with one end and stretches into the inside drain pipe of valve body, the fixed valve gap that is provided with in valve body top, the intermediate position of valve gap is provided with the bellied cavity that makes progress, the inside float that is provided with of valve body, the top of float is provided with and is provided with the sealed raft board that can insert the drain pipe with cavity interference fit's guide bar, below, sealed raft board sets up to the big, the little circular cone platform structure of lower extreme in upper end, guide bar and sealed raft board are on same center axis and when float up-and-down motion guide bar and sealed raft board do not deviate from cavity.
The utility model discloses technical scheme's further improvement lies in: and a sealing plug matched with the sealing raft plate when the floater falls down completely is arranged at the port of the drain pipe in the valve body.
The utility model discloses technical scheme's further improvement lies in: the valve body is connected with the valve cover through a bolt.
The utility model discloses technical scheme's further improvement lies in: the floater is in a cylindrical cavity structure.
Due to the adoption of the technical scheme, the utility model discloses the technological progress who gains is:
the utility model arranges the float in the valve body, when the water medium in the water supply and drainage system flows into the valve body through the water inlet pipe, the water level in the valve body gradually rises to cause the float to float upwards under the action of buoyancy, the sealing raft floats upwards along with the float, a gap is generated between the sealing raft and the sealing plug, and the water in the valve body flows out from the drain pipe through the gap; when water supply and drainage system cut off, the decline float along with the water level in the valve body can fall by oneself, realizes automatic drainage and closes, the utility model discloses a valve can self-closing, the pipe seal, thereby harmful gas is difficult to leak and avoids causing danger, the utility model discloses need not manual operation, simple structure is stable durable.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
wherein, 1, valve cover; 2. a valve body; 3. a float; 4. a sealing plug; 5. a drain pipe; 6. and (4) a water inlet pipe.
Detailed Description
The present invention will be described in further detail with reference to the following examples:
as shown in fig. 1, a valve that can close by oneself, including valve body 2, 2 tops of valve body are provided with inlet tube 6, the below is provided with drain pipe 5, 2 tops of valve body are provided with valve gap 1 through the bolt fastening, the intermediate position of valve gap 1 is provided with the bellied cavity that makes progress, the inside float 3 that is provided with cylinder cavity structure of valve body 2, the top of float 3 is provided with the sealing raft that can insert in the sealing plug 4 that 5 ports of drain pipe set up with cavity interference fit's guide bar, below, the sealing raft sets up to the big, little circular cone platform structure of lower extreme in upper end, when float 3 falls completely, sealing plug 4 and sealing raft complete cooperation, guide bar and sealing raft do not deviate from cavity and drain pipe 5 on same central axis and float 3 up-and-down motion time.
When the water medium in the water supply and drainage system flows into the valve body 2 through the water inlet pipe, the floater 3 floats upwards under the action of buoyancy along with the gradual rise of the water level in the valve body 2, the sealing raft floats upwards along with the floater 3, a gap is formed between the sealing raft and the sealing plug 4, and the water in the valve body 2 flows out of the water discharge pipe 5 through the gap; when the water supply and drainage system stops water supply, the water level in the valve body 2 is lowered, the sealing valve plate arranged at the lower part of the floater 3 and the guide rod arranged at the upper part of the floater 3 realize the consistency of the up-and-down action of the floater 3, when the water level is lowered to a certain position, the sealing valve plate is accurately inserted into the sealing plug 4 to realize the closing of the valve, the valve does not need manual operation, and the valve is simple in structure, stable and durable.
Claims (4)
