Compared with the prior art, the beneficial effect of this application is:

when the water quantity control metering valve is used, the metering valve comprises an initial state, a water passing state and a water stopping state.

In the initial state of the metering valve, the outlet hollow rod does not bear downward acting force, and at the moment, the upper end of the plug is in sealing contact with the outlet bearing platform to isolate the outlet cavity from the preposed cavity. When the water supply device is used, a water source is communicated with the supply cavity, water enters the supply cavity and then enters the preposed cavity through the inlet hollow rod, and after the water enters the preposed cavity, the outlet cavity is isolated from the preposed cavity because the upper end of the plug is in sealing contact with the outlet bearing platform, and the water stops after the preposed cavity is filled with the water.

If wanting to get into the logical water state, then exert downward effort to the part that the hollow pole of export is located the upper end opening outside of tubular structure, the hollow pole of export downstream under downward effort to drive export diaphragm piece and down become the heart in order to compress the export spring, the hollow pole of export of downstream pushes up the end cap downstream simultaneously, the limit valve is in logical water state this moment, thereby the end cap no longer with export plummer sealing contact, export cavity and leading cavity intercommunication this moment, water in the leading cavity is shoved into the export cavity, and carry outside the export cavity through the hollow pole of entry. It should be noted that, in the water-passing state, the downward movement of the plug pushes the inlet hollow rod to move downward and drives the inlet diaphragm to become center downward, at this time, the movable bearing platform on the inlet hollow rod continues to compress the inlet spring toward the inlet bearing platform, and at this time, the end opening of the inlet hollow rod is not yet in contact with the closed base. In the above, when the water is in the water passing state, the water flows through the supply cavity, the inlet hollow rod, the preposition cavity, the outlet cavity and the outlet hollow rod in sequence, and finally flows out through the outlet hollow rod.

The metering valve is switched from a water supply state to a water supply stop state, specifically, the outlet hollow rod continuously moves downwards along with the increase of a downward acting force applied to the outlet hollow rod, then the outlet hollow rod pushes the plug to move downwards, the plug pushes the inlet hollow rod to move downwards, finally the lower end opening of the inlet hollow rod is in sealing contact with the closed base in the supply cavity, so that the preposed cavity is isolated from the supply cavity, water only enters the supply cavity at the moment, but water cannot continuously flow to the inlet hollow rod, and the metering valve enters the water supply stop state at the moment.

When the downward force applied to the outlet hollow rod is completely removed, the metering valve is quickly returned to the initial state from the water-cut-off state. Specifically, after the downward force applied to the outlet hollow rod is completely removed, the inlet spring applies an upward force to the movable bearing table, so that the inlet hollow rod moves upward, the plug abuts against the outlet bearing table to completely isolate the outlet cavity from the pre-cavity, and the outlet spring also moves the outlet hollow rod upward to an initial state.

It can be seen from the working principle of the metering valve that the water outlet control of the metering valve only needs to apply continuously increased force to the outlet hollow rod, and finally the applied force is removed, so that the whole process of water supply and water cut-off can be completed. The whole process can completely depend on the downward acting force on the outlet hollow rod to control the water outlet amount, can realize the automatic stop of water receiving, does not relate to any circuit, is completely completed by the structure of the limit valve, and is safe and reliable.

In addition, the elastic force of the outlet spring and the elastic force of the inlet spring are reasonably selected or designed, so that the water cut-off state can be achieved only by determining how much downward acting force is applied to the outlet hollow rod, namely the acting force for starting and ending the water passing state of the metering valve is determined by the elastic force of the outlet spring and the elastic force of the inlet spring, and the water outlet quantity is better controlled.

When using the ration water receiving device of this application, the device that exerts the downward effort to the hollow pole of export in the above-mentioned is flourishing water receptacle promptly, and on the hollow pole of export was pegged graft to the check valve subassembly of flourishing water receptacle, the weight of flourishing water receptacle itself can trigger the water flow control limit valve and get into logical water state. Along with the increasing of the water quantity entering the water container by the water quantity control metering valve, the weight of the water container is increased continuously, the downward acting force applied to the outlet hollow rod is increased, and finally the water quantity control metering valve enters a water cut-off state. When the water container is taken away from the water quantity control metering valve, the downward acting force applied to the outlet hollow rod is completely released, and the water quantity control metering valve is quickly returned to the initial state from the water cut-off state. So, when we used the water, alright in order to realize ration water receiving and self-closing through this ration water receiving device and intake, avoided when the user is absent, caused the water waste, avoided the user not on the spot when water overflow, cause other losses.

The outlet hollow rod 20 is inserted into the outlet cavity 11 from the upper end opening of the tubular structure 10, the outer wall of the outlet hollow rod 20 is hermetically connected with the upper end opening of the tubular structure 10 through an outlet diaphragm 112, the outlet diaphragm 112 deforms in a preset range along with the up-and-down movement of the outlet hollow rod 20, and the outlet hollow rod 20 is communicated with the outlet cavity 11 and the outside of the upper end opening of the tubular structure 10.

The outlet spring 30 is sleeved on the outlet hollow rod 20 and arranged between the outlet bearing platform 111 and the outlet diaphragm 112, and the outlet spring 30 applies an acting force which is far away from the outlet diaphragm 112 and the outlet bearing platform 111, namely an acting force which moves upwards to the outlet hollow rod 20.

The front movable rod 40 comprises an inlet hollow rod 41 and a plug 42, the inlet hollow rod 41 is inserted into the front cavity 12 from the lower end opening of the tubular structure 10, the outer wall of the inlet hollow rod 41 is hermetically connected with the lower end opening of the tubular structure 10 through an inlet diaphragm 122, the inlet diaphragm 122 generates deformation within a preset range along with the up-and-down movement of the inlet hollow rod 41, and the inlet hollow rod 41 is communicated with the front cavity 12 and the outside of the lower end opening of the tubular structure 10; the bottom end of the plug 42 is connected with one end of the inlet hollow rod 41 positioned in the front cavity 12, the upper end of the plug 42 is connected with the outlet hollow rod 20, and the upper end of the plug 42 is used for abutting against the outlet bearing platform 111 to completely isolate the outlet cavity 11 from the front cavity 12; the outer wall of the joint of the inlet hollow rod 41 and the plug is provided with a movable bearing platform 411 in a surrounding mode.

The inlet spring 50 is sleeved on the inlet hollow rod 41 and is arranged between the movable bearing platform 411 and the inlet bearing platform 121, and the inlet spring 50 applies acting force which is far away from the inlet bearing platform 121 and the movable bearing platform 411, namely, applies acting force which moves upwards to the inlet hollow rod 41.

The supply cavity 60 is connected with the lower end opening of the tubular structure 10, a closed base 61 is arranged in the supply cavity 60, and the closed base 61 corresponds to the end part of the inlet hollow rod 41, which is positioned outside the lower end opening of the tubular structure 10; when the inlet hollow rod 41 is moved downwards to contact the closed base 61, the end opening of the inlet hollow rod 41 is sealed by the closed base 61 to completely isolate the pre-chamber 12 and the feeding chamber 60; the supply chamber 60 is connected to an external water source.

In the case of using the water amount control metering valve of the above embodiment, the metering valve includes an initial state, a water-passing state, and a water-stopping state. The whole water receiving principle of the metering valve from the initial state to the water passing state, from the water passing state to the water stopping state and from the water stopping state to the initial state is developed in detail as follows:

1) in the initial state of the metering valve, the outlet hollow shaft 20 is not subjected to a downward force, and the upper end of the stopper 42 is in sealing contact with the outlet support 111 to isolate the outlet chamber 11 from the pre-chamber 12. When the water-saving type water supply device is used, a water source is connected into the supply cavity 60, water enters the supply cavity 60 and then enters the preposed cavity 12 through the inlet hollow rod 41, after the water enters the preposed cavity 12, the outlet cavity 11 is isolated from the preposed cavity 12 because the upper end of the plug 42 is in sealing contact with the outlet bearing platform 111, and the water stops after the preposed cavity 12 is filled with the water.

2) If the metering valve wants to enter the water passing state, a downward acting force is applied to the part of the outlet hollow rod 20, which is positioned outside the upper end opening of the tubular structure 10, the outlet hollow rod 20 moves downward under the downward acting force and drives the outlet diaphragm 112 to become center downward to compress the outlet spring 30, meanwhile, the outlet hollow rod 20 moving downward pushes against the plug 42 to move downward, the metering valve is in the water passing state, so that the plug 42 is not in sealing contact with the outlet bearing platform 111 any more, at the moment, the outlet cavity 11 is communicated with the front cavity 12, and water in the front cavity 12 rushes into the outlet cavity 11 and is conveyed out of the outlet cavity 11 through the inlet hollow rod 41. It should be noted that, in the water-passing state, the downward movement of the plug 42 pushes the inlet hollow rod 41 to move downward and drives the inlet diaphragm 122 to become center downward, and at this time, the movable bearing platform 411 on the inlet hollow rod 41 continues to compress the inlet spring 50 toward the inlet bearing platform 121, and at this time, the end opening of the inlet hollow rod 41 is not yet in contact with the sealing base 61. As described above, in the water flowing state, the water flows through the supply chamber 60, the inlet hollow rod 41, the pre-chamber 12, the outlet chamber 11, and the outlet hollow rod 20 in this order, and finally flows out through the outlet hollow rod 20.

3) The metering valve is then switched from the water-supply state to the water-stop state, specifically, as the downward force applied to the outlet hollow rod 20 increases, the outlet hollow rod 20 continues to move downward, and further moves downward against the plug 42, which pushes the inlet hollow rod 41 downward, and finally the lower opening of the inlet hollow rod 41 is in sealing contact with the closed base 61 in the supply cavity 60, so as to isolate the pre-cavity 12 from the supply cavity 60, and at this time, the metering valve enters the water-stop state, in which the water flow only enters the supply cavity 60, but cannot continue to flow to the inlet hollow rod 41.

4) When the downward force applied to the outlet hollow stem 20 is completely removed, the metering valve is quickly returned from the water-off state to the initial state. Specifically, after the downward force applied to the outlet hollow rod 20 is completely removed, the inlet spring 50 applies an upward force to the movable carrier 411, so that the inlet hollow rod 41 moves upward to make the plug 42 abut against the outlet carrier 111 to completely isolate the outlet cavity 11 from the pre-cavity 12, and the outlet spring 30 also moves the outlet hollow rod 20 upward to the initial state.

From the working principle of the metering valve, it can be seen that the water outlet control of the metering valve can complete the whole process of water supply and water cut-off only by applying continuously increased force to the outlet hollow rod 20 and finally removing the applied force. The whole process can completely depend on the downward acting force on the outlet hollow rod 20 to control the water outlet amount, can realize the automatic stop of water receiving, does not relate to any circuit, completely depends on the structure of a limit valve to complete, and is safe and reliable.

In addition, the elastic forces of the outlet spring 30 and the inlet spring 50 are reasonably selected or designed to determine how much downward acting force is applied to the outlet hollow rod 20 to enter the water cut-off state, that is, the magnitude of the acting force for starting and ending the water passing state of the metering valve is determined by the elastic forces of the outlet spring 30 and the inlet spring 50, so that the water outlet amount is better controlled.

In one embodiment, the sealing base 61 may be made of a soft material such as rubber, so that the inlet hollow rod 41 is better sealed with the sealing base 61.

In one embodiment, referring to fig. 1, the upper end of the inlet hollow rod 41 is provided with a cylindrical base 421 concentrically fitted with the lower end of the stopper 42, and the lower end of the stopper 42 is slidable up and down in the cylindrical base 421. A jacking spring 43 is arranged between the plug 42 and the cylindrical base 421, the jacking spring 43 is sleeved on the plug 42, and the jacking spring 43 applies a mutually-away acting force to the plug 42 and the cylindrical base 421, namely the jacking spring 43 applies an upward-moving acting force to the plug 42. It has been described above that the inlet spring 50 exerts an upward force on the inlet hollow rod 41 to seal the outlet support 111 against the plug 42, and further exerts a secondary lifting force through the lifting spring 43 to seal the plug 42 to the outlet support 111 more tightly and also to return the plug 42 more quickly.

In one embodiment, referring to fig. 1, the front cavity 12 includes a middle cavity 13 and an inlet cavity 14 sequentially connected from top to bottom, a limiting bearing platform 131 is disposed at the junction of the middle cavity 13 and the inlet cavity 14, the inner diameter of the limiting bearing platform 131 is smaller than the outer diameter of the movable bearing platform 411, and the limiting bearing platform 131 limits the movable bearing platform 411 to continue moving upwards. The cylinder base 421 is installed at the junction of the middle chamber 13 and the inlet chamber 14, and the lower surface of the cylinder base 421 is flush with the limiting bearing table 131. This corresponds to increasing the distance of the plug 42 moving downwards along the cylindrical base 421 when the plug 42 moves downwards, and the bottom end of the plug 42 will push the inlet hollow rod 41 to move downwards when moving to the bottom end of the cylindrical base 421. It can be seen that the downward force is required to overcome the force of the jacking springs 43 in addition to the force of the outlet springs 30 and the inlet springs 50. Therefore, the downward acting force required for starting and ending the water passing state of the metering valve is flexibly adjusted by reasonably selecting or designing the elastic force of the outlet spring 30, the inlet spring 50 and the jacking spring 43, so that the water outlet quantity of the metering valve is more finely controlled.

In one embodiment, referring to fig. 1, the outlet chamber 11, the intermediate chamber 13 and the inlet chamber 14 are of a split structure, and can be detachably and hermetically connected with each other, so as to facilitate subsequent disassembly and assembly and maintenance. The junction of the outlet chamber 11, the intermediate chamber 13 and the inlet chamber 14 is provided with a seal to enhance the sealing effect.

In one embodiment, referring to fig. 1, an outlet cover 70 is installed at the upper opening of the cylindrical structure 10, and the outlet cover 70 is provided with a through hole matching with the outer diameter of the outlet hollow rod 20; the outlet diaphragm 112 is located on the underside of the outlet cover 70, and the outlet cover 70 limits the upward continued deformation of the outlet diaphragm 112. The inlet bearing platform 121 encloses a through hole with an inner diameter matched with the outer diameter of the inlet hollow rod 41, the inlet diaphragm 122 is positioned at the lower side of the inlet bearing platform 121, and the inlet bearing platform 121 limits the upward continuous deformation of the inlet diaphragm 122.

In one embodiment, referring to fig. 1, the plug 42 is provided with a sealing gasket 44 at a position for abutting against the outlet carrier 111. The sealing ring 44 ensures that the sealing effect between the plug 42 and the outlet support 111 is better.

In one embodiment, the supply chamber 60 is provided with a connector (not numbered) on the side for quick connection with an external water line.

According to a second aspect of the present application, referring to fig. 3 to 5, there is also provided a quantitative water receiving device, comprising the water quantity control limit valve in the above solution, and further comprising a water container 100. The bottom of the water container 100 is provided with a check valve assembly 200 inserted into the outlet hollow rod 20 of the water quantity control metering valve.

When the quantitative water receiving device of the embodiment is used, the device applying the downward acting force to the outlet hollow rod 20 is the water container 100, the check valve assembly 200 of the water container 100 is inserted into the outlet hollow rod 20, and the weight of the water container 100 can trigger the water quantity control limiting valve to enter the water passing state. As the amount of water entering the water container 100 through the water amount control metering valve increases, the weight of the water container 100 increases, the downward force applied to the outlet hollow rod 20 increases, and finally the water amount control metering valve enters a water stop state. When the water containing implement 100 is removed from the flow control metering valve, which corresponds to complete removal of the downward force applied to the outlet hollow stem 20, the flow control metering valve is quickly returned from the water-off condition to the initial condition. So, when we used the water, alright in order to realize ration water receiving and self-closing through this ration water receiving device and intake, avoided when the user is absent, caused the water waste, avoided the user not on the spot when water overflow, cause other losses.

In one embodiment, referring to fig. 5, the check valve assembly 200 includes a vertically extending mounting cavity 210, a hollow socket 220, a check steel ball 230, a steel ball seat 240, and a thrust spring 250; the lower end opening of the mounting cavity 210 faces to the outside, and the upper end opening thereof is communicated with the inside of the water container 100; the hollow socket 220 is arranged at the lower opening of the mounting cavity 210 and is used for being plugged with the outlet hollow rod 20 of the water quantity control limit valve; the steel ball seat 240 is installed and limited between the upper end opening of the installation cavity 210 and the hollow socket 220; the check steel ball 230 is arranged between the steel ball seat 240 and the hollow socket 220, and the diameter of the check steel ball 230 is larger than the inner diameter of the through hole of the hollow socket 220; the reverse spring 250 is arranged between the steel ball seat 240 and the upper opening of the mounting cavity 210 and the steel ball seat 240, and the reverse spring 250 applies acting force which is far away from the steel ball seat 240 and the upper opening of the mounting cavity 210; when the installation cavity 210 is not in an upward water injection type, the reverse pushing spring 250 enables the steel ball seat 240 to move downwards so that the reverse stopping steel ball 230 blocks the through hole of the hollow socket 220, thereby preventing bottom water leakage when the water container 100 is taken away.

In one embodiment, referring to fig. 5, the unidirectional valve assembly 200 further comprises a check rubber cap 260, the check rubber cap 260 being mounted at the upper end opening of the mounting chamber 210. No water is injected into the upper opening of the mounting cavity 210, and the water pressure in the water container 100 causes the non-return rubber cap 260 to be attached to and seal the upper opening of the mounting cavity 210, thereby preventing the water container 100 from leaking.
