Abstract
A draining water valve is prepared as setting valve body to be cavity structure with water inlet and water outlet at two ends of cavity body, setting float spool at internal of cavity structure and coordinating external surface of said spool to water outlet on cavity body in order to seal water outlet on cavity body when float spool is contacted with said water outlet.
Description
One, technical field: the present invention relates to a kind of drainage valve, especially a kind of structure of turning back on undirected is not allowed susceptible to plugging drainage valve, and it is used for below the pond in house or the ground leak.
Two, background technology: pass through in the sewer pipe inlet chamber in order to prevent pernicious gas and insects such as cockroach, mouse in the outdoor blowdown pipe network, people usually install launching gears such as re-current inlet, floor drain and manual water plug near the indoor following mouth of a river, in pernicious gas and insect inlet chamber in the prevention blowdown pipe network.But all there are some defectives in these launching gears, re-current inlet and floor drain as present use, its principle is upwards to turn back after the structure in the use device flows down water within it again and then flow down, meeting keeps some water in is installing the intact back of current down like this, utilizes these waters to cut off the passage of indoor and outdoor blowdown pipe network.Shortcoming is: just lost effect after 1. these waters are evaporated.2. its principle and structural reason cause current not smooth, stop up easily, and usually the phenomenon of metalling run out of Fa Shenging is exactly an illustration.Also have the manual water plug, majority is installed in the delivery port place in pond, and manual operation will descend the mouth of a river to open, and blocks up.Shortcoming is that operation is frequent, uses very inconvenient.
Three, summary of the invention:
1, goal of the invention: the invention provides a kind of drainage valve, its objective is that solving the existing drainage valve that has re-current inlet makes current not smooth, and the operation of manual water plug is frequent, the problem that aspects such as use inconvenience exist.
2, technical scheme: the present invention is achieved through the following technical solutions:
A kind of drainage valve is characterized in that: this valve comprises:
Valve body is cavity body structure, and the two ends of cavity are respectively equipped with water inlet and delivery port, water inlet and delivery port and middle chamber internal communication;
Floating plug is located in the middle chamber of valve body, and the delivery port in the external surface of floating plug and the valve body cavity adapts, the delivery port when both contact in the floating plug closed valve cavity.
The proportion of floating plug is in 0.1～0.8 scope.
The proportion of floating plug is preferably in 0.2～0.5 scope.
Valve body is formed by fixedly connecting by upper valve body and following valve body, and the upper valve body upper end is provided with water inlet, and following valve body lower end is provided with delivery port, and water inlet is connected the valve body inside cavity connection that the back forms with delivery port with upper and lower valve body.
Floating plug is spheroid, hollow ball, oval-shaped ball or oval hollow ball.
Floating plug is connected with the valve plug of delivery port in the closed valve cavity below by connecting rod, is provided with backstay below the valve plug; The delivery port place is provided with alignment pin in the valve body cavity, and backstay is movably arranged in the alignment pin.
Valve body is made of upper and lower valve body, and upper valve body is the loam cake that has the inlet opening, and it covers on the upper end open of lower valve body cavity body, is provided with backstay below the floating plug.
3, advantage and effect: by the enforcement of technical solution of the present invention, can solve well existing when having re-current inlet drainage valve make current not smooth, and the operation of manual water plug is frequent, the problem of using aspect such as inconvenience to exist.The present invention has utilized the principle of buoyancy and gravity to realize the automatic opening and closing of drainage valve, compares with the manual water plug to have made things convenient for use.Do not have down current following times when drainage valve is long-time, floating plug fall can close chamber in the passage of outdoor blowdown pipe network, it is long-time when anhydrous to be better than present floor drain, re-current inlet, just ineffective after the water of preservation is evaporated.Also have valve inner of the present invention and spool all can adopt fluid design, the structure of turning back on undirected on the structure is so be not easy to stop up.The present invention is relatively simple for structure, and production and processing is easy, and cost is not high, and is practical.This drainage valve is as following current following times, and drainage valve is opened automatically, and water is flowed down smoothly.Instantly the intact back of current drainage valve is closed again automatically, and does not allow susceptible to plugging drainage valve.Being provided with of valve plug, backstay, alignment pin reaches better sealing effect in the time of can guaranteeing anhydrous outflow.
