Abstract
The utility model relates to the technical field of valves, in particular to an improved check valve, which is characterized in that a valve shell comprises a water inlet valve port and a water outlet valve port which is positioned on the right side; a valve jacket is arranged at a flange mouth at the upper end of the valve shell; a copper collar pad is arranged at the lower end of the valve jacket; an upper water outlet valve port is arranged inside the valve jacket; and an inner-cavity of the valve shell is a three-way high-capacity channel, on the inner side of which a valve flap is arranged. Compared with the prior art, the improved check valve has the characteristics of high flow capacity, low resistance, no suspension of feculences, tight closure, the realization of single closure and single conduction, expense economization, simple structure and convenient use as well as installation.
Description
[technical field]
The utility model relates to valve technology field, specifically a kind of modified model safety check.
[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 is exactly will solve above-mentioned deficiency and a kind of valve body that provides adopts the full tunnel structure, and it is big to have a flow, and resistance is little, does not hang the modified model safety check of dirt.
For achieving the above object, the utility model proposes a kind of modified model safety check, comprise valve casing, it is characterized in that: 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 valve casing, and copper ring pad is equipped with in the valve sleeve lower end, has upside water outlet valve port in the valve sleeve, 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 three-dimensional.
Described flap comprises copper ring, and global body is housed on the copper ring, and flap one end is fixed by stationary axle and described valve casing.
The beneficial effects of the utility model:
1. valve body of the present utility model 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 simple in structure, characteristics easy to install and use, have applicable to various high viscositys in the industry and domestic sewage pipe network of suspended matter, press the 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]
Fig. 1 is a structural representation of the present utility model.
[embodiment]
Embodiment 1:
The modified model safety check, its composition comprises valve casing, 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 valve casing 1, copper ring pad 13 is equipped with in valve sleeve 4 lower ends, have upside water outlet valve port 6 in the 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 modified model safety check, 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 modified model safety check, 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: nature, flap 5 is sagging naturally, current flow into from described water inlet valve port 2, promoting described flap 5 opens, 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, and 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, adjusts 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.
Claims (2)
1. modified model safety check, comprise valve casing, it is characterized in that: 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 valve casing, copper ring pad is equipped with in the valve sleeve lower end, have upside water outlet valve port in the valve sleeve, 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 three-dimensional.
