Technical Field

The invention relates to the field of valves, in particular to the field of a toilet flushing valve.

Background

The most used scheme is to supply water according to a set sequence by a device or a valve group with a plurality of flushing ports or water inlets, wherein the system needs to be controlled by an electromagnetic valve and a control system, and the electric energy control system is easy to break down. For water-saving toilet bowls, such as the toilet bowl with publication number CN111173103A, the flushing ports flush water simultaneously, which is relatively water-consuming, and the flushing ports flush water simultaneously, which is also insufficient.

Under the condition that the toilet is provided with a plurality of flushing ports, if the existing flushing toilet, especially the existing flushing toilet using the pressure potential energy of water, wants to reach the requirement of cleaner flushing of the toilet under the condition of low water pressure, and is not easy to realize.

The rotary toilet has larger flushing pressure and larger noise in the flushing process.

This phenomenon is common in both cities and rural areas.

Disclosure of Invention

If the water flushing at each position adopts the set sequence, compared with the water flushing at the same time, the water can be saved, and meanwhile, the better flushing effect can be achieved.

The valve of the invention is used for separately processing the flushing water of each part of the toilet, gradually flushing each part under the condition of keeping the supply of the flushing water unchanged, improving the flushing quality of each part, and greatly reducing the noise in the flushing process because the flushing water of the toilet is carried out in stages. The valve of the invention comprises a first pipeline, an outlet pipeline, a second pipeline or a third pipeline, wherein after pressure water flow enters from the first pipeline, the pressure water flow can flow out from the outlet pipeline or the third pipeline, after the pressure water flow enters the valve, a valve plug moves, the valve plug moves to the maximum stroke position, the outlet pipeline stops water outlet or has very small flow, meanwhile, the second pipeline or the third pipeline is communicated with the first pipeline, the second pipeline or the third pipeline becomes a second outlet pipeline or a water inlet pipeline of a second valve, the valves of the invention are connected in series, the second pipeline or the third pipeline of the first valve is communicated with the first pipeline of the second valve, the second pipeline or the third pipeline of the second valve is communicated with the first pipeline of the third valve, and a plurality of water outlet holes of a toilet can be sequentially controlled by flushing sequence. The invention valve, the stool pot in the patent application disclosed in the background technology, most of the stool falls on the piston and then slides to the stool pot pipeline, the stool pot hardly remains filth, all the positions spray water according to the set sequence: the flushing of the toilet bowl is controlled by the valve, the flushing time is as short as possible, water is saved, the flushing on the surface of the flushing piston is earlier than the flushing of the driving piston in rotation, and the flushing of the toilet bowl is beneficial to reducing the phenomenon that the dirt on the piston is thrown to a toilet pipeline near a supporting part for supporting the piston and preferentially falls to the bottom of the toilet pipeline from the lowest position of the piston.

The specific implementation mode is as follows:

the valve of the invention, especially the toilet valve, comprises two valves with subtle differences.

The first valve comprises a valve cavity 4, a valve plug 5, a pull rod 1, a first pipeline 2, a second pipeline 6 and a water outlet pipeline 3, wherein the valve plug is positioned in the cavity and can move up and down in the cavity, the valve plug is connected with the pull rod, the other end of the pull rod penetrates out of the cavity, the valve further comprises a second pipeline and a plunger, the first pipeline is an inlet pipeline and a valve in a static state, the first pipeline is communicated with the water outlet pipeline, the second pipeline is blocked by the plunger, pressure water flows through the first pipeline and enters the cavity, and then the valve plug moves to one side of the pull rod, and the valve plug reaches the maximum moving position and then: the second pipeline is not being communicated with first pipeline by plunger shutoff, and first pipeline is not being communicated or the intercommunication passageway has only tiny gap with outlet conduit, and the valve is intake and is ended, and valve plug rising pressure disappears, and the valve plug receives the restoring force downwards and returns original quiescent condition, the restoring force includes valve plug and the decurrent gravity of pull rod or the restoring force of spring to the valve plug. The spring is located between the fixed valve component and the movable valve plug or the pull rod, after the valve plug is moved by water pressure, the state change of the spring has restoring force, and after the pressure of water flow in the valve disappears, the restoring force of the spring enables the valve plug to restore to the position of a static state.

Valve plug both sides, pressure rivers can circulate, and rivers get into valve cavity after, the valve plug both sides all receive water pressure, and it is big that the valve plug does not receive water pressure on one side of the pull rod, and the valve plug both sides pressure differential is greater than spring potential energy, and the valve plug receives water pressure differential to move to pull rod one side, and valve pressure water pressure disappears, and the valve plug receives the spring restoring force to reply.

Preferably, the valve plug has a through hole 8 through which the pressurized water flow can reach the other side of the piston after entering the valve chamber.

Preferably, the valve includes montant 9, and valve quiescent condition montant is located valve plug through-hole 8, and when the valve plug received water pressure to remove to the maximum position, the montant did not appear great passageway in the through-hole or with the through-hole. The water flow capacity of the two sides of the piston is set according to the interval between the water outlet time of the second pipeline and the water outlet time of the water outlet pipeline, the water flow of the two sides of the piston with short interval is required to be faster, and the water flow of the two sides of the piston with long interval is required to be slower.

The second valve comprises a valve cavity 4, a valve plug 5, a pull rod 1, a first pipeline 2, a water outlet pipeline 3 and a third pipeline 10, the valve plug is positioned in the cavity body, the valve plug can move up and down in the cavity body, the valve plug is connected with the pull rod, the other end of the pull rod penetrates out of the cavity body, it is characterized in that the valve also comprises a third pipeline, the first pipeline is a water inlet pipeline, and when the valve is in a static state, first pipeline and outlet conduit intercommunication, pressure water flows through behind first pipeline entering cavity, and the valve plug moves to pull rod one side, and first pipeline and the indirect intercommunication of third pipeline, after the valve plug reachd the maximum shift position, first pipeline and outlet conduit are not only in the tiny gap of intercommunication or intercommunication passageway, and first pipeline and third pipeline keep the intercommunication, and the valve is intake and is ended, and the valve plug upwards pressure disappears, and the valve plug receives the downward restoring force to reply original quiescent condition, the restoring force includes valve plug and the decurrent gravity of pull rod or the restoring force of spring to the valve plug.
