Description

Toilet bowl pressure stabilizing valve

Technical Field

The utility model belongs to the technical field of the closestool, especially, relate to a closestool surge damping valve.

Background

The intelligent closestool has a plurality of special functions, such as buttocks cleaning, lower body cleaning, moving cleaning, seat ring heat preservation, warm air drying, automatic deodorization, mute sitting and the like. Most conveniently, except that the operation can be carried out through the button panel, the remote control device is specially arranged to realize the functions, and when a consumer uses the remote control device, all the functions can be easily realized by holding the remote control device with a hand and slightly pressing the remote control device. The water inlet pressure needs to be stabilized in consideration of comfort in use. The pressure stabilizer usually uses a pressure stabilizing valve, and the pressure stabilizing valve mainly comprises a regulating spring, a diaphragm, a piston, a valve seat, a valve clack and other parts. The diaphragm is used for directly sensing downstream pressure to drive the valve clack, and the opening degree of the valve clack is controlled to complete the functions of pressure reduction and pressure stabilization. The product can replace the conventional subarea water pipe in the cold and hot water supply system of urban buildings and high-rise buildings, and saves equipment. It can also be used in common cold and hot water pipe network to reduce and stabilize pressure. The pressure reducing and stabilizing valve has the structural characteristics. The pressure stabilizing valve has the general control principle that when water is supplied from the water inlet end of the pipeline, water flows through the needle valve and enters the control chamber of the main valve, the outlet pressure acts on the pilot valve through the guide pipe, when the outlet pressure is higher than the set value of the pilot valve, the pilot valve is closed, the control chamber stops draining water, at the moment, the pressure in the control chamber of the main valve rises and closes the main valve, and the outlet pressure does not rise any more. When the outlet pressure drops to the pilot set pressure the pilot valve opens and the control chamber drains downstream. Because the water displacement of the pilot valve is greater than the water inflow of the needle valve, the pressure in the control chamber of the main valve is reduced, and the inlet pressure opens the main valve. In a stable state, the water inlet and the water discharge of the control chamber are the same, the opening degree is unchanged, and the outlet pressure is unchanged.

At present, a pressure stabilizing technology is applied to an intelligent closestool, for example, patent CN206368985U discloses a closestool and a pressure stabilizing valve thereof, wherein the pressure stabilizing valve comprises a shell, a valve core, a valve plate assembly and a spring. The shell is provided with a water inlet, a water outlet, a first cavity and a second cavity, the water inlet is communicated with the first cavity, the first cavity is communicated with the second cavity through a communicating hole, and the second cavity is communicated with the water outlet. The valve core comprises a first end part, a middle part and a second end part, the middle part is positioned between the first end part and the second end part, the first end part is contained in the first cavity, the middle part is close to or far away from the communication hole so as to adjust the flow passing through the communication hole, and the second end part penetrates through the communication hole and extends into the second cavity. The valve block assembly is arranged on the second end portion of the valve core, one end of the spring is abutted to the inner wall of the second cavity, the other end of the spring is abutted to the valve block assembly, and the spring is always in a compression state. The flow through the communicating holes is adjusted, so that the impact force and the pre-pressure of the spring are balanced, and the stable water pressure of the discharged water can be effectively ensured. However, the device has a big problem that the water pressure of the water inlet can directly impact the pressure stabilizing valve, particularly the valve core which plays a key role in stabilizing the pressure; because water pressure is unstable, the valve core is loosened and even damaged for a long time, so that the pressure stabilizing effect is lost, the service life of the pressure stabilizing valve is shortened, the whole pressure stabilizing valve needs to be replaced, and the maintenance cost is high.
