Abstract
The utility model discloses a triangular valve provided with an anti-reverse-flow device. The triangular valve provided with the anti-reverse-flow device comprises a triangular valve body, wherein the triangular valve body is provided with a water inlet and a rotating handle, an anti-reverse-flow valve seat is welded on the triangular valve body, one end of the anti-reverse-flow valve core stretches into the anti-reverse-flow valve seat to be matched with a central hole which is formed in the bottom of the anti-reverse-flow valve seat, a spring which is sleeved on the anti-reverse-flow valve core is correspondingly fixed with a supporting ring, the supporting ring is fixed by a support which is arranged above a bottom hole and connected to the inner wall of the anti-reverse-flow valve seat, and the other end of the anti-reverse-flow valve core is connected with a threaded port. The anti-reverse-flow device is reasonable in design and accurate in positioning, when used in an actual use process, the anti-reverse-flow device is smooth in inflowing and little in leakage when the anti-reverse-flow device is used for reverse flow resistance, and water pollution caused by sewage reverse flowing can be effectively prevented.
Description
Technical field
The utility model relates to a kind of triangle vavle, is specifically related to a kind of triangle vavle that is provided with backflow protection device.
Background technique
Existing triangle vavle in use when the siphon pressure of cutting off the water reduces, easily causes the adverse current of water owing to there is not backflow protection device, can pollute whole water quality thereby sewage enters intake pipe.In daily life, if the triangle vavle that flush toilet cistern, vegetable sink or washbasin use does not have anti-adverse current function, very easily cause the pollution of potable water, endanger healthy.
The model utility content
Technical problem to be solved in the utility model provides a kind of triangle vavle that is provided with backflow protection device reasonable in design, long-lived.
For solving the problems of the technologies described above, a kind of triangle vavle that is provided with backflow protection device of the utility model, comprise the triangle valve body, described triangle valve body is provided with water intake and rotatable handle, the valve for preventing reverse-flow seat is welded on the described triangle valve body, one end of valve for preventing reverse-flow core extend into the center hole that arranges with valve for preventing reverse-flow seat bottom in the valve for preventing reverse-flow seat and matches, the spring that is sleeved on the valve for preventing reverse-flow core is corresponding with support ring fixing, described support ring is fixed by the support that places on the bottom outlet and be connected on the valve for preventing reverse-flow seat inwall, and the other end of valve for preventing reverse-flow core is connected with threaded coupling.
For improving anti-reverse fluidity energy better, guarantee the accurate location of valve for preventing reverse-flow core, the support of said fixing support ring is three, and is evenly arranged on the inwall of described valve for preventing reverse-flow seat.
Above-mentioned rotatable handle is provided with antiskid groove.
Compared with prior art, the beneficial effects of the utility model are: backflow protection device of the present utility model is reasonable in design, its accurate positioning, and water inlet is smooth in the actual using process, seepage is few when preventing adverse current, can prevent effectively that the water that counter-current of sewage brings from polluting.This real new structure is simple, durable in use, installs backflow protection device additional at triangle vavle commonly used and gets final product, and repacking is convenient, and with low cost being easy to promoted.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a kind of structural representation that is provided with the triangle vavle of backflow protection device of the utility model;
Fig. 2 is the structural representation of valve for preventing reverse-flow seat of the present utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of triangle vavle that is provided with backflow protection device, comprise triangle valve body 1, described triangle valve body 1 is provided with water intake 11 and rotatable handle 12, valve for preventing reverse-flow seat 2 is welded on the described triangle valve body 1, one end of valve for preventing reverse-flow core 4 extend into the center hole 23 that arranges with valve for preventing reverse-flow seat 2 bottoms in the valve for preventing reverse-flow seat 2 and matches, the spring 3 that is sleeved on the valve for preventing reverse-flow core 4 is corresponding fixing with support ring 24, described support ring 24 is fixing by the support 22 that places on the bottom outlet 21 and be connected on valve for preventing reverse-flow seat 2 inwalls, and the other end of valve for preventing reverse-flow core 4 is connected with threaded coupling 5.
The support 22 of described fixed support ring 24 is three, and is evenly arranged on the inwall of described valve for preventing reverse-flow seat 2.Described rotatable handle 12 is provided with antiskid groove.
When water inlet, rotate rotatable handle 12 adjusting inflow sizes, promote valve for preventing reverse-flow core 4 compression springs 3 this moment under the hydraulic pressure effect, and valve for preventing reverse-flow core 4 breaks away from threaded coupling 5, and water enters valve for preventing reverse-flow seat 2 and enters cistern at this moment; When hydraulic pressure reduction situation such as cut off the water took place, under spring 3 self elastic force effect, valve for preventing reverse-flow core 4 was closely fixing with threaded coupling 5, and the water in the cistern can not adverse current enter water intake 11, can prevent effectively that the water that counter-current of sewage brings from polluting.
