Definitions
- the present invention relates to a fluid valve, particularly a level control valve for a toilet tank, and a corresponding control method.
- a liquid level control valve with a float In the toilet inlet control device, a liquid level control valve with a float has been widely used.
- This type of valve uses the buoyancy of the float to control its water intake according to the water level of the tank, and automatically replenishes the water volume of the tank. Among them, the opening and closing of the valve is completed by the lifting device, so that the up and down displacement of the buoy is controlled to the needle valve, the tray, the water stop rubber pad and the like.
- the present invention discloses a water inlet valve for a toilet, and the technical solution thereof is:
- a toilet inlet valve includes a valve body, an inlet pipe, a water stop device with a water stop pad, a pontoon device, a lifting device and an outlet pipe, and the water stopping device further comprises:
- a water stop seat located at the front end of the water outlet pipe, the opening of which cooperates with the end surface of the water stop rubber pad;
- a tray connected to the water stop pad, located on an opposite side of the water stop seat relative to the water stop pad;
- a back pressure chamber which is a cavity having a pressure relief hole, accommodates the tray and the needle valve, and the back pressure chamber has a needle valve hole that sleeves the needle valve.
- a toilet inlet valve includes a valve body, an inlet pipe, a water stop device with a water stop pad, a pontoon device, a lifting device and an outlet pipe, wherein the water stopping device further comprises:
- a tray connected to the water stop pad, located on an opposite side of the water stop seat relative to the water stop pad;
- a back pressure chamber which is a cavity having a pressure relief hole, accommodates the tray and the needle valve, and the back pressure chamber has a needle valve hole that sleeves the needle valve.
- the needle valve can be divided into two sections according to its axial direction, namely:
- the matching section of the needle valve has a circular cross section, and the outer surface of the gap section has a groove extending axially to the tray along the needle valve.
- the needle valve engagement section has a circular cross section, and the gap section has a circular cross section, and the clearance section has a cross sectional diameter smaller than a cross section diameter of the matching section.
- the inlet flow inlet may have a filter with a screen.
- the filter screen inlet orientation can be set to be perpendicular to the direction of the water flow vector from the inlet pipe.
- the outside of the water inlet pipe may have a coaxial air bag cavity, and the bottom of the air bag cavity includes an annular elastic air bag.
- the fluid chamber at the bottom of the inlet pipe may have a rotating structure.
- the tray of both solutions may be bowl-shaped with a cylindrical side on its outer side.
- the control method of the present invention includes a steady state and two dynamics:
- the pressure relief port is blocked, and only one water inlet of the back pressure chamber is a gap between the needle valve and the needle valve hole;
- the back pressure chamber is filled with water, and the water stop rubber pad is on the back
- the pressure of the water pressure in the pressure chamber is equal to the external pressure, the water stop rubber is stationary and blocks the water stop seat, and the tray and the needle valve are also stationary, and the needle valve engagement section is located in the needle valve hole;
- Dynamic one on the basis of the steady state, the pressure relief port is opened, so that the water in the back pressure chamber quickly flows out from the pressure relief port, and the internal pressure thereof is rapidly reduced;
- the pressure of the water pressure in the back pressure chamber is significantly smaller than the external pressure, and thus the external water pressure forces the water stop pad together with the tray and the needle valve to retract into the back pressure chamber, and as the retraction stroke increases,
- the needle valve first has a matching section located in the needle valve hole, and secondly travels to the gap section; the dynamic one can summarize the process of opening the water pad;
- Dynamic two on the basis of the dynamic one, the pressure relief port is blocked, and the water in the inlet pipe flows into the back pressure chamber from the gap between the needle valve hole and the needle valve, and the water in the back pressure chamber begins to increase; As the water increases, the pressure in the back pressure chamber increases, the tray pushes the water stop pad outwardly toward the back pressure chamber, and at the same time drives the needle valve to travel backward in the needle valve hole relative to the dynamic one, thereby The needle valve is firstly a gap section in the needle valve hole, followed by a matching section. This change reduces the water inlet speed in the back pressure chamber, and reduces the speed of pressurization in the back pressure chamber, thereby alleviating the pressure on the tray. The pad occludes the speed of the water stop; this dynamic can be summarized as the process of damping the closure of the water pad until it reaches a steady state.
- the tray and the needle valve are fixedly interlocked, and the gap between the needle valve and the needle valve hole is the water inlet of the back pressure chamber, and the water inlet is located on the opposite side of the water stop rubber pad and the tray, and the movable sleeve is sleeved in the hole of the hard needle valve, and the back thereof
- the water inlet of the pressure chamber is away from the valve stop member, and the gap between the needle valve and the needle valve hole is stabilized, so noise and vibration are reduced during operation.
- the needle valve Due to the use of the two-stage needle valve structure, the needle valve has a damped closing process in the working cycle, thereby greatly reducing the shock and vibration caused by the water stop, and reducing the collision wear and working noise of each component.
- the coaxial air bag chamber outside the inlet pipe has the effect of splitting and decompressing the fluid when the entire valve is filled with water.
- the fluid chamber at the bottom of the inlet pipe is rotated by a revolving structure to restrict the flow vector; this rotating water path causes most of the impact energy in the water stream to be properly decomposed and absorbed, greatly avoiding the vibration and noise caused by the impact.

- Embodiment 1 is a diagrammatic representation of Embodiment 1:
- FIG. 2 and FIG. 3 are overviews of an embodiment of the present invention.
- 1 is the body of the valve, the tray 2, the water stop pad 3, the needle valve 4, the needle valve cover 5 constitute the main components of the water stop device, wherein the needle valve cover 5 also has a pressure relief hole 52; 6 is an elastic airbag, 7 is a filter, 8 is a filter; 9 is a screw head, 10 is an inlet pipe; 11 is a lifting rod, 12 is a rubber pad, 121 is a pressure relief port, 13 is a buoy, 14 is an outlet pipe , 15 is the adjustment rod, 16 is the water stop; the arrows in the figure indicate the direction of water flow.
- FIG. 6 the main part of the back pressure chamber is a needle valve cover 5 , and the tray 2 is fixed to one end of the gap section of the needle valve 4 .
- the front end of the tray 2 passes through and is fixed to the top end of the water stop pad 3; and the engagement section of the needle valve 4 is inserted into the needle valve hole 51 of the needle valve cover 5, and although it is shaped to fit, it can be freely slid and non-liquid sealed.
- the relationship between the water stop pad 3, the tray 2 and the needle valve 4 in the module A is shown from another perspective in Fig. 8; the exploded view of the module B is shown in Fig. 7.
- the elastic air bag 6 is sleeved on the bottom of the water inlet pipe 10, and the screw head 9 is sleeved on the water inlet pipe; the bottom of the water inlet pipe 10 has a rotating fluid chamber 101.
- FIGS. 9 and 10 are schematic views of the two needle valves mounted on the tray 2, respectively.
- the needle valve 4 shown in Fig. 9 has a circular cross section of the matching section 41, and the gap section 42 includes circumferentially distributed grooves;
- the needle valve 4 shown in Fig. 10 has a circular cross section in the cross section 41, and the cross section 42 is also circular in cross section, and its diameter is smaller than the matching section 41.
- Dry road the water flow in the inlet pipe 10 enters the inlet pipe fluid chamber 101, Then, it is screwed into the water stop pad 3 to form a reverse water pressure on the water stop pad 3, and the water pressure direction is completely opposite to the water flow direction in the water inlet pipe 10;
- Control branch this way enters the inner cavity of the filter 7 through the filter 8, so as to pass through the gap between the needle valve 4 and the needle valve hole 51 (Fig. 6), reaches the back pressure chamber including the needle valve cover 5, and gives the tray 2 A forward water pressure, which is in the same direction as the water flow in the inlet pipe 10.
- the liquid level in the entire water tank causes the pontoon 13 to rise to the closed position, at which time the pontoon controls the upper rubber pad 12 to block its corresponding pressure relief port 121 through the adjusting rod 15, so that the back pressure chamber where the needle valve cover 5 is located
- the forward water pressure in the middle is consistent with the reverse water pressure in the dry road. Due to the difference in the effective area design of the water pressure on both sides of the water stop pad 2, the forward water pressure is greater than the reverse water pressure, so that the tray 2 flows out.
- the direction is pressed against the water stop pad 3, and the water stop pad 3 blocks the water stop seat 16, stopping the flow of water from the trunk road to the outlet pipe;
- the buoy 13 is lowered, and the upper rubber pad 12 no longer blocks the pressure relief port 121, so that the forward water pressure in the back pressure chamber where the needle valve cover 5 is located is rapidly reduced.
- the reverse water pressure in the trunk road does not change, so the water stop pad 3 and the tray 2 both retreat under the reverse water pressure, and the water stop seat 16 is opened, so that the trunk water flow smoothly flows down the pipe wall 14 .
- the outlet pipe will always be out of water to raise the tank level until it rises to the closed position.
- the upper rubber pad 12 blocks the pressure relief port 121 again, and the forward water pressure in the back pressure chamber where the needle valve cover 5 is located starts to rise; in the process, the water from the inlet pipe 10 flows through the needle valve 4 and the needle.
- the gap of the valve hole 51, the pressing tray 2 starts to move toward the water discharge direction, and gradually presses the water stop rubber pad 3; in this process, the gap between the needle valve 4 and the needle valve hole 51 is first, and the water flow rate is large; when the tray 2 is constantly moving When the needle valve 4 is moved in the needle valve hole 51, the needle valve 4 will gradually enter the needle valve hole 51, replacing the position of the original gap section, thereby reducing the flow velocity of the water flow and alleviating the trend of increasing the forward water pressure.
- the tray 2 is slowly pressed against the water stop pad 3 until the water stop pad 3 seals the water outlet seat 16.
- the two-stage structure of the needle valve 4 determines the water stop mode of the step, and reduces the vibration and noise inside the valve body during the entire water stop process.
- Embodiment 2 is a diagrammatic representation of Embodiment 1:
- FIG 11 is a view showing another embodiment of the present invention.
- the water stop device itself includes the relative positions of the tray 2, the water stop pad 3, the needle valve 4, and the back pressure chamber 52. Function; the difference is that the direction of the entire water stop device relative to the inlet and outlet pipes is opposite to that of the first embodiment, because the end of the inlet pipe 10 is the water stop seat 16, and the water stop seat 16 is abutted against the water stop pad 3 and can be The water stop rubber pad 3 is blocked; the water outlet pipe 14 is connected to the cavity outside the water stop seat 16;
- Dry road the water flow in the inlet pipe 10 enters the inlet pipe fluid chamber, and a reverse water pressure is formed on the water stop rubber pad 3, and the water pressure direction is exactly the same as the water flow direction in the inlet pipe 10;
- the water flow of the control branch enters the filter 7 through the passage 102, and then enters the back pressure chamber 52 through the needle valve 4; when the tray 2 presses the water stop rubber pad 3 to block the water stop seat 16 downward, the water flow of the inlet water pipe 10 is closed; When the pressure relief port 121 is opened to reduce the water pressure in the back pressure chamber 52, the water stop rubber pad 3 is pressed by the water pressure of the water inlet pipe 10 to press the tray 2 to rise, and the water stop seat 16 is opened, so that the water outlet pipe 14 and the water inlet pipe 10 Connected, the water flows out (in the opposite direction to the inlet water); the needle valve 4 still moves synchronously with the tray 2.
- the valve body of the present invention divides the water flow into two paths, one for the trunk road and the other for the control branch:
- the water flow of the dry road reaches the water stop rubber pad, forming a reverse water pressure on the water stop rubber pad; the water flowing through the control branch passes through the gap between the needle valve and the needle valve hole, reaches the back pressure chamber including the needle valve cover, and is given
- the tray is in a forward water pressure.
- the gap between the needle valve and the needle valve hole is stable, so noise and vibration are reduced during operation. Due to the use of the two-stage needle valve structure, the needle valve has a damped closing process in the working cycle, thereby greatly reducing the shock and vibration caused by the water stop, and reducing the collision wear and working noise of each component.
