Description

Synchronous double-switch valve plate assembly and synchronous double-switch valve core

Technical Field

The utility model relates to a case, in particular to synchronous two switch valve block subassemblies and synchronous two switch valve cores.

Background

The switch valve core is a device for controlling water flow. When the switch valve core is closed, the water inlet pressure acts on the fixed valve plate, so that the movable valve plate is subjected to an acting force which is separated from the fixed valve plate in a fitting state under the action of water pressure. The maximum water pressure value which can be borne by the switch valve core in the closed state is the pressure resistance capacity of the switch valve core. The national standard has requirements on the pressure resistance of the switch valve core, and when the pressure resistance of the switch valve core is low, if the water inlet pressure is high, the movable valve plate and the fixed valve plate can be separated, and the switch valve core is exploded, so that the valve core cannot be used.

Chinese patent No. 201820148045.7 discloses a synchronous double switch case (hereinafter referred to as a reference), including moving valve plate and fixed valve plate, set up one on the moving valve plate and crossed water tank and one, cross the water tank and run through the moving valve plate, thereby can introduce the water in the water tank to the moving valve plate outside, make the moving valve plate upper surface also can receive the effect of pressure of intaking, avoid because the single face of moving valve plate bottom surface receives the pressure effect of intaking, it takes place to break away from the phenomenon and takes place to avoid taking place between moving valve plate and the moving valve plate when pressure of intaking is great, thereby improve the holistic pressure-resisting ability of case.

In the above-mentioned patent, set up on the movable valve piece and cross behind the water through-hole, when two business turn over water holes that diagonal angle set up were connected with the inlet channel, this case can realize two-way intaking. As shown in fig. 7 of the comparison document, at this time, the valve element is in a closed state, 51a is communicated with hot water inlet, 51b is communicated with cold water inlet, and because 51a and 51b are blocked by the lower surface of the passive valve plate and the area of the lower surface of the movable valve plate opposite to 51a and 51b is smaller, the force generated by the inlet water pressure on the movable valve plate is smaller, and the valve element has better pressure resistance. When the whole valve core rotates 90 degrees anticlockwise and is installed in the valve core cavity, the 51d and 51c are respectively connected with hot water inlet water and cold water inlet water, and the cold water inlet water is introduced to the upper surface of the movable valve plate by the 42b, so that the water pressure borne by the movable valve plate faces the fixed valve plate, and the valve core also has better pressure resistance. The valve core has good pressure resistance when water is fed in the forward direction (namely water is fed into the 51a and 51b which are arranged diagonally, and water is discharged from the 51c and 51 d), and has good pressure resistance when water is fed in the reverse direction (namely water is fed into the 51c and 51d, and water is discharged from the 51a and 51 b), so that the valve core can realize bidirectional water feeding, the position of a water inlet and a water outlet is not required to be particularly noticed when the valve core is installed, and the valve core is convenient to use.

When two adjacent water inlet and outlet holes that set up are connected with the inlet channel, this case can also have the function of intaking. As shown in fig. 7, when 51a is connected to the hot water inlet (or cold water inlet) and 51c is connected to the cold water inlet (or hot water inlet), and in the closed state, 42b guides the cold water inlet to the back of the movable valve plate, and the movable valve plate presses the fixed valve plate under the action of water pressure, the valve core has better pressure resistance. When the movable valve plate rotates clockwise by 45 degrees from the closed state, hot water inlet is communicated with cold water inlet, the cold water inlet pressure is generally greater than the hot water inlet pressure, and therefore cold water flows into a water tank of the solar water heater to supply water. When the movable valve plate rotates 45 degrees anticlockwise from the closed state, the movable valve plate 51c is communicated with the movable valve plate 51b, the movable valve plate 51a is communicated with the movable valve plate 51d, and water is discharged normally. However, because the number of the water passing holes on the movable valve plate is only one, when two adjacent water inlet and outlet holes of the valve core are connected with the water inlet pipeline, only forward water inlet can bear larger water inlet pressure, and reverse water inlet cannot bear higher water pressure.

Although the valve core has better pressure resistance, the water feeding function can be realized when adjacent water is fed, and the function of bidirectional water feeding is realized when diagonal water is fed, the water is directly communicated with the outer side of the movable valve plate when the valve core is used, so that at least one sealing ring needs to be arranged on the outer side of the upper end of the valve core shell, and at least one sealing ring also needs to be arranged between the rotating shaft and the shell. The increased number of the sealing rings can increase the water leakage probability and increase the torque of the rotating shaft during rotation, so that the overall cost of the valve core is higher, and the torque required during rotation is larger.

It is assumed that the water through hole 42b on the movable valve plate in the comparison document is simply set as a semi-closed water through groove without changing the shape of the communication groove on the lower surface of the movable valve plate. Referring to the comparison document of fig. 7, if two water inlet and outlet holes arranged diagonally are filled with water, the valve core has better pressure resistance when the water is filled in the closing state of the forward water inlet, namely, the water is filled in the 51a and the 51 b. When the reverse water inlet closed state is realized, namely water is fed into the water inlet holes 51d and 51c, the top surfaces of the 42a and 42b are both under the action of water inlet pressure, and the area of the top surfaces of the 42a and 42b is far larger than the sectional area of the water inlet and outlet holes, so that the pressure resistance of the valve core is poor. The valve core has better pressure resistance when only water is fed in the forward direction, and has poorer pressure resistance when water is fed in the reverse direction.

Simultaneously, if when adjacent intaking, two adjacent business turn over water holes communicate with two inlet channels respectively, when the case was in the off-state, must have one to cross the effect that the basin top surface received water pressure, and the power that the movable valve block received and breaks away from the laminating with the fixed valve block is great this moment, and the whole withstand voltage ability of case is poor, and the case can explode when water pressure is great, can't realize the function of watering.

as shown in fig. 16 to 17, the difference between the fourth embodiment and the first embodiment is the size of the water inlet and outlet through holes on the fixed valve plate 55 and the shape of the water passing groove on the movable valve plate 4. The diameter of the water inlet and outlet through hole in the fixed valve plate 5 is slightly smaller than that of the water inlet and outlet through hole in the first embodiment, and the water inlet and outlet through hole is closer to the center of the fixed valve plate 5. Meanwhile, as shown in fig. 16, the first water passing groove 10 and the second water passing groove 11 on the movable valve plate 4 are arc-shaped, and the arc-shaped opening faces the center of the movable valve plate 44.

As shown in FIG. 17, at this time, the valve core is in a closed state, the two water inlet channels are respectively connected with the first water inlet and outlet through hole 6 and the third water inlet and outlet through hole 8 of the valve core, the first water outlet pipeline is communicated with the second water inlet and outlet through hole 7, and the second water outlet pipeline is communicated with the fourth water inlet and outlet through hole 9. At the moment, the valve core has no water feeding function.

If the water supply function is needed, only two water inlet pipelines are respectively communicated with the first water inlet and outlet through hole 6 and the fourth water inlet and outlet through hole 9, so that the second water outlet through hole 7 is communicated with one water outlet pipeline, and the third water outlet through hole 8 is communicated with the other water outlet pipeline.

In the fifth embodiment, a synchronous dual-switch valve core,

as shown in fig. 18 and 19, the difference between the fifth embodiment and the second embodiment is that in the fifth embodiment, the spring 22 and the limiting member 23 are longitudinally arranged, the opening of the mounting hole 21 faces the top of the housing 1, so that after the spring 22 and the limiting member 23 are mounted in the mounting hole 21, the limiting member 23 abuts against the top surface of the inner wall of the housing 1 under the action of the spring 22. Meanwhile, the limiting groove 24 is also positioned on the top of the inner wall of the shell 1, and the limiting groove 24 comprises a complete opening limiting groove 35, a closed state limiting groove 36 and a maximum water feeding state limiting groove 37. When the limiting member 23 is engaged in the limiting groove 24, the valve core is in a fully opened state, a closed state and a maximum water feeding state.
