Abstract
The utility model relates to a pipe valve, in particular to a water pressure type automatic dredging valve which can prevent pipe for transmitting liquid from being blocked and particularly prevent sewage water from returning in water pipes under high buildings. the utility model is provided with a pipe-shaped valve with a water-in port and a water-out port; a blade-shaped valve core is arranged in the pipe-shaped valve, one end of the blade-shaped valve core is fixed and the other end of the blade-shaped valve core is free; the diameter of the water-out end of the valve core is bigger than the water-out port, and the valve core is a round blade; the valve core facing to the water-in port of the pipe-shaped valve is an plastic blade provided with sealing function, the other face of the valve core is a hard blade provided with anti-pressure function; the utility model has a simple and reasonable structure, convenient operation; and the utility model can be ensured to prevent waste water, sewage water from returning when the downcomer is blocked, and the utility model flushes blocking things by the principle of liquid pressure.
Description
Technical field
The utility model relates to a kind of pipeline valve, especially relates to a kind of line clogging that can prevent to carry liquid, and particularly the hydraulic type of highrise building sewer pipe obstruction sewage refluence is dredged valve automatically.
Background technology
As everyone knows, highrise building sewer pipe structure is the interworking architecture that sagging interface, elbow, threeway, water pipe and the main sewer pipe of each floor is formed by connecting and constitutes.Because main sewer pipe is a common part, the utilization rate height, main in daily life sewer pipe elbow and treatment pond join, this section of tubing very easily stops up, because obstruction is to accumulate over a long period to pile up the back blocking pipe, be difficult in the use early finding, in case sewer pipe stops up the phenomenon that just must cause low floor user wastewater and sewage to flow backwards.
Summary of the invention
The purpose of this utility model be overcome above-mentioned the deficiencies in the prior art provide a kind of simple in structure, the structure reasonable, easy to use, guarantee when sewer stops up, can prevent that the hydraulic type that the liquid pressure principle washes away obstruction that utilizes of waste water, sewage refluence from dredging valve automatically.
The utility model is realized in the following way:
A kind of hydraulic type is dredged valve automatically, it is characterized in that: it comprises the tubular valve body that has water inlet and delivery port, be provided with fixedly other end sheet spool freely of an end in this valve body, spool is the garden shape sheet of the diameter of close above-mentioned delivery port one end greater than the delivery port diameter, spool towards above-mentioned water inlet is the sheet of moulding with sealing function, and another side is the hard sheet with resistance to compression effect;
The cylindrical of described spool is provided with the boss that fixes with described valve interior wall;
The diameter of described spool is greater than the diameter of described water inlet;
The diameter of described water inlet and delivery port is less than the diameter of described valve body.
The utlity model has following effect:
The utility model be exactly installed one in the tubular valve body additional can be along with the end that the flow direction of current is opened, closed be fixed end sheet spool freely, thereby simple in structure, this valve can be with processing with the sewer pipe identical materials, and is convenient, practical.
The utility model is to design according to liquid principle of pressure in container, the hydraulic type that the utility model is provided dredges the water inlet of valve automatically and each user's sewer pipe joins, delivery port communicates with public sewer pipe, when public sewer pipe is blocked, sewage just flows in the valve body along public sewer pipe, because the valve body spool is along with current are free movable, the pressure of the sewage in user's the sewer pipe is less than the pressure of sewage in the public sewer pipe at this moment, when sewage flows to spool, rely on the pressure of sewage self make spool freely an end towards the direction motion of water inlet, because the diameter of spool is greater than the diameter of water inlet, thereby spool is blocked water inlet, because spool simultaneously has sealing function, thereby along with the rising sewage pressure of public sewer pipe water level increases, thereby spool is tight more with water inlet sealing, and sewage just can not adverse current goes out the following mouth of a river of each household.Because the pressure of liquid is directly proportional with the height of liquid, just big more so wastewater level is high more to the pressure of public sewer pipe obstruction, when pressure acquires a certain degree, rely on sewage pressure that obstruction is rushed in treatment tank.At this moment, the pressure that the each household sewer pipe produces is greater than the pressure of the sewage in the common sewer, when the sewage of each household flows to spool, rely on the pressure of sewage self make spool freely an end towards the direction motion of delivery port, thereby spool opened, thereby it is unimpeded to recover sewer pipe, reaches the purpose of dredging automatically with hydraulic pressure.
The hydraulic type that the utility model provides is dredged valve automatically and is applicable to all pipe-line for conveying liquids, thereby possesses production and life aspect that certain altitude utilizes obstruction in the self-pressure liquid dredging pipe.

Fig. 2 is the structural representation that the utility model and sewer pipe join;
Fig. 3 is the structural representation of the utility model spool.
The specific embodiment
A kind of hydraulic type is dredged valve automatically, as shown in Figure 1: it comprises the tubular valve body 4 that has water inlet 1 and delivery port 5, be provided with fixedly other end sheet spool 9 freely of an end in this valve body 4, spool 9 is the diameter of close delivery port 5 one ends garden shape sheets greater than delivery port 5 diameters, towards the spool of water inlet 1 be have a sealing function mould sheet 2, another side is the hard sheet 3 with resistance to compression effect, as shown in Figure 3, the cylindrical of spool 9 is provided with the boss 11 that fixes with valve body 4 inwalls, spool 9 is fixed on the inwall of valve body 4 by boss 11, the diameter of spool 9 is greater than the diameter of described water inlet 1, and the diameter of water inlet 1 and delivery port 5 is less than the diameter of described valve body 4.
As shown in Figure 2, water inlet 1 joins with each user's sewer pipe 6, delivery port 5 communicates with public sewer pipe 7, when public sewer pipe 7 is blocked, sewage just flows in the valve body 4 along public sewer pipe 7, because the spool 9 in the valve body 4 is along with current are free movable, the pressure of the sewage in user's the sewer pipe 6 is less than the pressure of sewage in the public sewer pipe 7 at this moment, when sewage flows to spool 9, rely on the pressure of sewage self make spool 9 freely an end towards the direction motion of water inlet 1, because the diameter of spool 9 is greater than the diameter of water inlet 1, thereby spool 9 is blocked water inlet 1, along with the rising sewage pressure of public sewer pipe 7 water levels increases, thus spool 9 tight more with water inlet 1 sealing, and sewage just can not adverse current goes out the following mouth of a river of each household.Wastewater level is high more, and is just big more to the pressure of public sewer pipe 7 obstructions, when pressure acquires a certain degree, relies on sewage pressure that obstruction is rushed in treatment tank 10.At this moment, the pressure that each household sewer pipe 6 produces is greater than the pressure of the sewage in the common sewer 7, when the sewage of each household flows to spool 9, rely on the pressure of sewage self make spool 9 freely an end towards the direction motion of delivery port 5, thereby spool 9 opened, thereby it is unimpeded to recover sewer pipe, reaches the purpose of dredging automatically with hydraulic pressure.
