Abstract
The utility model relates to a three-way double-directional check valve. The existing check valve of which the valve body is provided with a single channel has the disadvantages of big volume, easy blocking, small flow, only unidirectional installation and high cost; in addition, caps are easily inverse; the ordinary three-way valve is only closed at one direction; the inner cavity is easy to hang dirt; valve positions are not accurate, the ordinary three-way valve can only closed tightly under powerful water pressure. The three-way double-directional check valve comprises a valve shell 1, an inlet valve opening 2 arranged at the valve shell 1 and an outlet valve opening 3 at the right side; a valve sleeve 4 is arranged at the position of a flange opening at the upper end of the valve shell 1; a copper ring pad 13 is arranged at the lower end of the valve sleeve 4; an outlet valve opening 6 at the upper side is arranged in the valve sleeve 4; a three-way high-capacity channel 7 is arranged at the inner cavity of the valve shell 1; a valve flap 5 is arranged at the inner side of the three-way high-capacity channel 7. The utility model is used in various industrial and domestic sewer pipe screens of fire-fighting, boiler furnaces with suspended substances of high viscosity.
Description
Technical field: the utility model relates to a kind of threeway dual way check valve.
Background technique: the valve body of existing safety check is a single channel, its shortcoming is that big, the easy obstruction of volume, flow are little, resistance is big, and easy anti-cap can only unidirectionally be installed, and the cost height, common three-phase valve can only unidirectionally cut out, its inner chamber hangs dirt easily, and flap walks inaccurate, must have powerful hydraulic pressure just can close sternly.
Summary of the invention: the purpose of this utility model provides a kind of valve body and adopts the full tunnel structure, and it is big to have a flow, and resistance is little, does not hang the threeway dual way check valve of dirt.
Above-mentioned purpose realizes by following technological scheme:
The threeway dual way check valve, its composition comprises: valve casing, described valve casing has into water valve port and right side water outlet valve port, valve sleeve is equipped with at the upper flanges mouth place of described valve casing, copper ring pad is equipped with in described valve sleeve lower end, have upside water outlet valve port in the described valve sleeve, described valve shell cavity is the big capacity passage of three-dimensional, and flap is equipped with in the inboard of the big capacity passage of described three-dimensional.
Above-mentioned threeway dual way check valve, described flap comprises copper ring, and global body is housed on the described copper ring, described flap one end is fixed by stationary axle and described valve casing.
Above-mentioned threeway dual way check valve, described valve casing and described valve sleeve are fixed with screw, and adjusting screw is equipped with in described valve casing lower end.
This technological scheme has following beneficial effect:
1. threeway dual way check valve of the present utility model, its valve body adopts the big capacity channel design of three-dimensional, thereby it is big to have a flow, and resistance is little, does not hang dirt, closes characteristics such as tight.
2. the flap of this product is to be combined by the copper ring and the whole world to form, and fixedlys connected with the valve body employing, has solved the weakness of common individual event safety check individual event path, can realize the individual event closure, and a lot of unnecessary expenditures are saved in the individual event conducting in pipe network connects.
3. on the valve body of this product adjusting screw is housed, the opening angle of may command flap.
4. this product has characteristics simple in structure, easy to install and use, has applicable to various high viscositys in the industry and domestic sewage pipe network of suspended matter, pressure frequency conversion feedwater, heat pipeline, and adopt the standard flange mouth, can install by any direction, and not limited by the orientation.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
Embodiment:
Embodiment 1:
The threeway dual way check valve, its composition comprises: valve casing 1, described valve casing 1 has into water valve port 2 and right side water outlet valve port 3, valve sleeve 4 is equipped with at the upper flanges mouth place of described valve casing 1, copper ring pad 13 is equipped with in described valve sleeve 4 lower ends, have upside water outlet valve port 6 in the described valve sleeve 4, described valve casing 1 inner chamber is the big capacity passage 7 of three-dimensional, and flap 5 is equipped with in the inboard of the big capacity passage 7 of described three-dimensional.
Embodiment 2:
Above-mentioned threeway dual way check valve, described flap 5 comprises copper ring 8, and global body 9 is housed on the described copper ring 8, described flap 5 one ends are fixed by stationary axle 10 and described valve casing 1.
Embodiment 3:
Above-mentioned threeway dual way check valve, described valve casing 1 is fixing with described valve sleeve 4 usefulness screws 11, and adjusting screw 12 is equipped with in described valve casing 1 lower end.
Working procedure:
Above-mentioned threeway dual way check valve, nature, described flap 5 is sagging naturally, current flow into from described water inlet valve port 2, promote described flap 5 and open, water flows out from upside water outlet valve port 6 and right side water outlet valve port 3, under anhydrous situation, flap 5 is closed into water valve port 2, current flow into from described upside water outlet valve port 6, impact flap 5 whole world, close into water valve port 2, water flows out from right side water outlet valve port 3, adjust adjusting screw 12, flap 5 is opened, current flow into from described right side water outlet valve port 3, can control the water flow of upside water outlet valve port 6 and water inlet valve port 2, to reach the demand of control different amounts; The recoil state, described flap 5 is shifted onto described valve casing 1 upside water outlet valve port 2 places by current, and closes this mouthful, forms full tunnel, and current flow out from described right side water outlet valve port 3.
