Description

Technical Field

[0001] The invention relates to the technical field of pressurized water valves, in particular to an automatic induction pressurized water valve. Background Art

[0002] The valve is a control component in the fluid conveying system, which has the functions of shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. The valves used in fluid control systems are quite diverse in variety and specifications, from the simplest shutoff valve to the various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. When the traditional drain valve drains water, its drainage speed and water flow impact force are limited by the potential energy of the water in the water tank. When the water tank height is low, the drainage speed and water flow impact force of the drain valve will be greatly reduced, resulting in low water pressure. The current drain valve cannot pressurize the water flow during the drainage process, and cannot automatically adjust the pressurization degree according to the reduction of water in the water tank, resulting in unstable water pressure during drainage. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] In view of the deficiencies in the prior art, the present invention provides an automatic sensing pressurized water valve, which solves the problem that the current drain valve is unable to pressurize the water flow during drainage and is unable to automatically adjust the pressurization level according to the reduction of water in the water tank, resulting in unstable water pressure during drainage.

[0005] (II) Technical solution

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automatic induction pressurized water valve, specifically comprising:

[0007] A water outlet pipe, the bottom of which is connected to a water outlet head, and a pressurizing device is provided on the top of the inner wall of the water outlet pipe;

[0008] A sensing device, which is arranged on the top of the water outlet pipe, and the bottom of the sensing device is connected to the top of the water outlet pipe;

[0009] A fixing seat, which is provided with two groups and is respectively arranged on both sides of the sensing device, and the fixing seat is provided with a water inlet;

[0010] The pressurizing device comprises:

[0011] A rotating head, the top of which is provided with a water storage tank, and the bottom of the inner wall of the water storage tank is provided with a spiral water outlet hole;

[0012] A rotating gear is sleeved on the rotating head and fixedly connected to the rotating head. Fixed bearings are fixedly connected to both sides of the rotating gear.

[0013] A driving gear meshes with the rotating gear on one side. The driving shaft of the driving motor penetrates and is fixedly connected to the center position of the driving gear.

[0014] A pressurizing device is provided. Water in the water tank enters the interior of the pressurizing device through the water inlet. The water entering the interior of the pressurizing device first enters the interior of the water storage tank and is split into each spiral water outlet hole through the water storage tank. When the water in the water storage tank passes through the spiral water outlet hole, the driving motor drives the rotating head to rotate through the driving gear and the rotating gear. At this time, the water in the spiral water outlet hole can accelerate the flow rate under the action of centrifugal force, thereby increasing the impact force when the water is discharged and achieving the purpose of pressurization.

[0015] Preferably, the rotating head is arranged inside the water outlet pipe and is rotatably connected to the inner wall of the water outlet pipe through a sealing bearing. The water storage tank inside the rotating head is communicated with the water inlet.

[0016] Preferably, multiple groups of spiral water outlet holes are provided and are evenly distributed on the rotating head. The side of the fixed bearing away from the rotating gear is fixedly connected to the inner wall of the water outlet pipe.

[0017] Preferably, the outside of the rotating gear penetrates through the water outlet pipe and extends to the outside of the water outlet pipe. The top of the driving motor is fixedly connected to the fixed seat.

[0018] Preferably, the induction device includes:

[0019] A mounting seat. An induction sliding groove is provided at the top of the mounting seat. A push diaphragm is fixedly connected to the top inner wall of the induction sliding groove. The push diaphragm is provided. The push diaphragm and the elastic force combination of the return spring can drive the control piston to move, which is convenient to reduce the influence caused by the friction between the control piston and the control sliding groove. The push diaphragm can adapt to the movement of the control piston through its own deformation, so that the sealing effect inside the control sliding groove and the induction sliding groove is better, and the water inside the water tank is prevented from seeping into the induction sliding groove and the control sliding groove.

[0020] A control sliding groove is arranged at the bottom inner wall of the induction sliding groove. A control piston is slidably connected to the inner wall of the control sliding groove. The top of the control piston extends into the induction sliding groove and is fixedly connected to the push diaphragm.

[0021] A control rod is arranged at the bottom of the control piston and is fixedly connected to the control piston. A sliding contact is fixedly connected to the side of the control rod. A sliding switch piece is slidably connected to the side of the sliding contact.

[0022] A return spring is sleeved outside the control rod, and two ends of the return spring are respectively fixedly connected with the bottom of the control piston and the bottom of the inner wall of the control chute.

[0023] When the water volume in the water tank decreases, the water pressure at the water inlet decreases. At the same time, the water pressure thrust on the diaphragm decreases, so that the control piston moves upward under the pushing action of the return spring. The control piston drives the sliding contact to move upward. The sliding contact moves on the sliding switch piece, so as to control the driving motor to increase the speed, which is convenient to increase the centrifugal force inside the rotating head, so as to supplement the reduced water pressure at the water inlet through the centrifugal force, and make the impact force of the water flow remain constant during the drainage process of the water tank, and avoid the reduction of the water flow impact force with the decrease of the water volume inside the water tank.

[0024] Preferably, both sides of the mounting seat are fixedly connected with the fixed seat, and one side of the sliding switch piece away from the sliding contact is fixedly connected with the inner wall of the control chute.

[0025] Preferably, both the sliding contact and the sliding switch piece are arranged on the control circuit of the driving motor.

[0026] Preferably, the control piston includes a piston rod. One end of the piston rod penetrates through and is fixedly connected with a first piston head and a second piston head respectively. The end of the piston rod away from the second piston head is fixedly connected with an arc-shaped support plate. A control piston is provided, and two groups of piston heads are arranged inside the control piston, which can avoid the inclination of the control piston during the movement process, resulting in poor contact between the sliding contact and the sliding switch piece. And an arc-shaped support plate is provided, which can avoid the deformation of the pushing diaphragm squeezing into the part between the control piston and the induction chute, resulting in the obstruction of the movement of the control piston, making the device safer and more reliable to use.

[0027] Preferably, both the first piston head and the second piston head are slidably connected with the inner wall of the control chute, and the diameter of the arc-shaped support plate is adapted to the diameter of the inner wall of the induction chute.

[0028] (III) Beneficial effects

[0029] The present invention provides an automatic induction pressurized water valve, which has the following beneficial effects:

[0030] (I). For the automatic induction pressurized water valve, a pressurizing device is provided. The water in the water tank enters the inside of the pressurizing device through the water inlet. The water entering the inside of the pressurizing device first enters the inside of the water storage tank, and is shunted into each spiral water outlet hole through the water storage tank. When the water in the water storage tank passes through the spiral water outlet hole, the driving motor drives the rotating head to rotate through the driving gear and the rotating gear. At this time, the water inside the spiral water outlet hole can accelerate the flow rate under the action of centrifugal force, so as to increase the impact force when the water flow is discharged, and achieve the purpose of pressurization.

[0031] (2). This automatic induction pressurized water valve is provided with an induction device. When the water volume inside the water tank decreases, the water pressure at the water inlet decreases. At the same time, the water pressure thrust on the diaphragm decreases, causing the control piston to move upward under the pushing action of the return spring. The control piston drives the sliding contact to move upward. The sliding contact moves on the sliding switch piece, which can control the driving motor to increase the speed, facilitating the increase of the centrifugal force inside the rotating head, thereby supplementing the reduced water pressure at the water inlet through the centrifugal force, making it convenient to keep the impact force of the water flow constant during the drainage process of the water tank and avoiding the decrease of the water flow impact force as the water volume inside the water tank decreases.

[0032] (3). This automatic induction pressurized water valve is provided with a pushing diaphragm, which can drive the control piston to move through the combined elastic force of the pushing diaphragm and the return spring, facilitating the reduction of the influence caused by the friction between the control piston and the control chute. The pushing diaphragm can adapt to the movement of the control piston through its own deformation, resulting in a better sealing effect inside the control chute and the induction chute, and preventing the water inside the water tank from seeping into the induction chute and the control chute.

[0033] (4). This automatic induction pressurized water valve is provided with a control piston. There are two sets of piston heads inside the control piston, which can prevent the control piston from tilting during movement, resulting in poor contact between the sliding contact and the sliding switch piece. And there is an arc-shaped support plate, which can prevent the deformation of the pushing diaphragm from squeezing into the part between the control piston and the induction chute, causing obstruction to the movement of the control piston, making the device safer and more reliable to use.
