Abstract
The utility model discloses a low-noise automatic air supply check valve for a pneumatic water storage tank, which includes a valve body, wherein a water inlet of a water pipe is connected with one end of the valve body, and a water outlet of the water storage tank is connected with the other end of the valve body; a valve hole used for communicating the water inlet with the water outlet is formed inside the valve body; an air suction valve used for communicating the valve hole is mounted at the side wall of the valve body; a valve rod in clearance fit with the valve hole is mounted inside the valve hole; the valve rod is provided with a stop part which is formed at the water inlet end of the valve hole and capable of being stopped at the water inlet end and allows water to enter the valve hole; a seal ring used for sealing the water outlet end of the valve hole is arranged at the valve rod and mounted at the water outlet end of the valve hole; and the length of the valve rod is designed to have the allowance for axially reciprocating motion inside the valve hole. The low-noise automatic air supply check valve taking the clearance between the valve rod and the valve hole as a water runner, enables the runner to be smooth, and avoids generating noise when water flows in, and besides, the low-noise automatic air supply check valve has a simple structure, is easy to machine, and is convenient and quick to assemble.
Description
Technical field
The utility model relates to the flap valve technical field, relates in particular to be applied to the flap valve of pneumatic storage tank.
Background technology
Pneumatic storage tank is to rely on the air pressure that exceeds atmospheric pressure in the water tank, and the water high-pressure injection in the water tank is come out, and reaches the purpose of flushing the toilet.Owing to the air in the water tank can be lost along with the bath each time of water tank, cause the water tank decompression, and can't flush the toilet.Therefore, behind Water flushing for cistern, need in water tank, to replenish air, to keep air storage stable in the water tank.
At present, be applied to a kind of flap valve of tonifying Qi automatically of pneumatic storage tank, this flap valve is equipped with inlet valve at its sidewall, flap valve is when water inlet, can form negative pressure at this end of valve opening of inlet valve, and then open inlet valve, be drawn into outside air in the valve opening of flap valve from inlet valve, enter into water tank again, in time with replenish air in water tank.This flap valve is installed a valve at water outlet end, and behind Water flushing for cistern, tap water can back down valve and enter water tank, and the water tank internal pressure raises gradually, until valve being pushed up back the shutoff water outlet end, finishes water tank water intake.The runner bending of the water that this valve forms is changeable, during water inlet, is easy to generate noise.And this valve process and assemble difficulty height, complex procedures.
The utility model content
The technical problems to be solved in the utility model provides a kind of automatic tonifying Qi flap valve of pneumatic storage tank of simple in structure, noise-decreasing.
The technical scheme that adopts for solving the problems of the technologies described above: a kind of automatic tonifying Qi flap valve of pneumatic storage tank of low noise, comprise a valve body, one end of valve body is for connecting the water inlet of water pipe, the other end is for connecting the delivery port of water tank, be provided with the valve opening that is communicated with water inlet and delivery port in the valve body, the sidewall of valve body is equipped with the inlet valve that is communicated with valve opening, it is characterized in that: the valve rod with its matched in clearance is installed in the described valve opening, valve rod is formed with in the inlet end of valve opening and can keeps off at this end and can allow water enter the stopper of valve opening, but valve rod is equipped with the sealing ring of this end of shutoff in the water outlet end of valve opening, and the length of valve rod is set as has the surplus that can axially move back and forth in valve opening.
Adopt the beneficial effect that the utility model brought: the valve of the flap valve of the utility model pneumatic storage tank is to be made of valve rod and sealing ring, valve rod directly cover is through in the valve opening, space between valve rod and the valve opening is as the runner of water, and runner is freely suitable, can not produce noise during water inlet.And the utility model is simple in structure, and easily processing is assembled also convenient and swift.
Description of drawings
Fig. 1 is the structural representation of automatic tonifying Qi flap valve of the pneumatic storage tank of the utility model low noise.
The specific embodiment
As shown in Figure 1, a kind of automatic tonifying Qi flap valve of pneumatic storage tank of low noise, comprise a valve body 1, one end of valve body 1 is for connecting the water inlet 11 of water pipe, the other end is for connecting the delivery port 12 of water tank, be provided with the valve opening 13 that is communicated with water inlet 11 and delivery port 12 in the valve body 1, the sidewall of valve body 1 is equipped with the inlet valve 2 that is communicated with valve opening 13.Valve rod 3 with its matched in clearance is installed in the described valve opening 13, valve rod 3 is formed with in the inlet end of valve opening 13 and can keeps off at this end and can allow water enter the stopper 31 of valve opening, but valve rod 3 is equipped with the sealing ring 4 of this end of shutoff in the water outlet end of valve opening 13, and the length of valve rod 3 is set as has the surplus that can axially move back and forth in valve opening 13.
After the pneumatic storage tank bath, the water tank internal pressure reduces, and tap water can head on as the valve rod 3 of valve and sealing ring 4 and up move, and opens valve, water enters water tank, with this simultaneously, inlet valve 2 is opened air-breathing, enters in the water tank together in company with water, up to casing internal pressure serious offense tap water pressure, pressing valve rod 3 and sealing ring 4 back to move, valve-off, while inlet valve 2 also pressurized cuts out.
