Description
Technical field
The present invention relates to spool, in particular to a kind of synchronous biswitch valve block component and synchronous biswitch spool.
Background technique
Switch valve core is the device for being controlled water flow.When switch valve core is closed, intake pressure acts on fixed
On valve block, so that moving valve plate is detached from the active force of fit-state by one with fixed valve plate under the action of water pressure.Switch valve core exists
The maximum hydraulic pressure value that can bear under closed state is its voltage endurance capability.Have in national standard to the voltage endurance capability of switch valve core
It is required that when the voltage endurance capability of switch valve core is lower, if intake pressure is higher to will lead to moving valve plate and fixed valve plate disengaging, switch valve
Core pops, so that spool is not available.
It is (hereinafter referred to as right that the Chinese patent of 201820148045 .7 of Patent No. discloses a kind of synchronous biswitch spool
Than file), including moving valve plate and fixed valve plate offer a water-carrying groove on moving valve plate and one are crossed water through-hole, cross water through-hole and pass through
Moving valve plate is worn, so as to which the water crossed in water through-hole to be introduced on the outside of moving valve plate, so that moving valve plate upper surface can also be intake
The effect of pressure, avoid due to moving valve plate bottom surface single side by intake pressure act on, when avoiding intake pressure larger moving valve plate with
Break-off occurs between moving valve plate, to improve the voltage endurance capability of spool entirety.
After water through-hole was arranged in above-mentioned patent, on moving valve plate, when two paddle holes and water inlet line being diagonally arranged
When connection, which can be realized two-way water inlet.As shown in documents Fig. 7, be now in closed state, 51a and hot water into
Water connection, 51b are connected to cold water water inlet, since the passive valve block lower surface 51a and 51b blocks, and the dynamic valve of 51a and 51b face
Piece lower surface area is smaller, so moving valve plate is also smaller by power caused by intake pressure, which has preferable pressure resistance
Ability.When entire spool, which rotates counterclockwise 90 degree, to be mounted in spool chamber, 51d and 51c are separately connected hot water water inlet and cold water
Water inlet, since cold water water inlet is introduced into moving valve plate upper surface by 42b, so the water pressure that moving valve plate is subject to is directed towards fixed valve plate
, so the spool also has preferable voltage endurance capability.Spool forward direction water inlet is (51a and the 51b water inlet being diagonally arranged, 51c
Be discharged with 51d) when there is preferable voltage endurance capability, while when reversed water inlet (i.e. 51c and 51d water inlet, 51a and 51b water outlet)
With preferable voltage endurance capability, so the spool may be implemented two-way water inlet, without paying special attention to the position of intake-outlet when installation
It sets, it is easy to use.
When two paddle holes being disposed adjacent are connect with water inlet line, which can also have the function of upper water.It is such as right
Than connecting when 51a connect 51c with hot water water inlet (perhaps cold water water inlet) with cold water water inlet (or hot water water inlet) shown in file map 7
It connects, when closed state, cold water water inlet is guided to the moving valve plate back side by 42b, and whole compress under the action of water pressure of moving valve plate determines valve at this time
Piece, spool have preferable voltage endurance capability.When moving valve plate rotates clockwise 45 degree from closed state, hot water water inlet and cold water into
Water connection, cold water intake pressure is greater than hot water intake pressure under normal circumstances, so cold water is flowed into the water of solar water heater
In case, water is carried out.When moving valve plate rotates counterclockwise 45 degree from closed state, 51c is connected to 51b, and 51a is connected to 51d, just
Often water outlet.But due to the water hole quantity on moving valve plate only one, so the spool adjacent two paddle holes with
When water inlet line connects, only positive water inlet is able to bear biggish intake pressure, unbearable higher hydraulic pressure of reversely intaking.
Although the spool has preferable voltage endurance capability, when adjacent water inlet, can be realized water function, and diagonal water inlet
When have the function of two-way water inlet, but when using water inlet directly be connected on the outside of moving valve plate, cause outside the spool housing upper end
Side needs that at least one of sealing ring is arranged, while setting at least sealing ring together is also required between shaft and shell.And sealing ring
Quantity increase will increase leak probability, increase torque when shaft rotation, so that spool overall cost is higher, when rotation is required
Torque is larger.
It is assumed that the water hole 42b in documents on moving valve plate is simply also configured as semi-enclosed water-carrying groove, without
Shape to connectivity slot in moving valve plate lower surface is changed.Referring to documents Fig. 7, if two Inlet and outlet waters being diagonally arranged
Hole water inlet, forward direction water inlet closed state when, i.e. 51a and 51b water inlet, the spool just has preferable voltage endurance capability at this time.When
When reversed water inlet closed state, i.e. when 51d and 51c are intake, the top surface 42a and 42b will receive intake pressure effect, and 42a and
42b top surface area is much larger than the sectional area of paddle hole, so spool voltage endurance capability is very poor at this time.This kind of spool only have it is positive into
There is preferable voltage endurance capability, spool voltage endurance capability is poor when reversed water inlet when water.
Meanwhile if two adjacent paddle holes are connected to two water inlet lines respectively, when spool is in when adjacent water inlet
When closed state, necessarily there is a water-carrying groove top surface by intake pressure, moving valve plate is detached from by with fixed valve plate at this time
The power of fitting is larger, and spool entirety voltage endurance capability is poor, and when hydraulic pressure is larger, spool can pop, and cannot achieve water function.
