Description
Technical field
The present invention relates to wastewater valve fields, and in particular to a kind of wastewater valve with scale-deposit-preventing and silencing function.
Background technique
Waste water ratio solenoid valve plays an important role in Water warfare, water treatment system, and wastewater valve is then used to control this
Waste water ratio.Traditional wastewater valve includes valve body, spool and executing agency, and the stream with water inlet and water outlet is provided in valve body
Road, is provided with annular partition in valve body, annular partition by runner be divided into positioned at center and with the inner flow passage of water inlet connection and
Around inner flow passage and the outer flow passage with water outlet connection, annular partition offers inner flow passage and outer flow passage connection and is used to adjust
The waste water hole of wastewater flow, the waste water hole are micropore, and annular partition is used as water cut off device, executing agency towards the open-ended of spool
Fixed valve body simultaneously drives the mobile spool that constitutes of spool to cooperate far from water cut off device or with water cut off device sealing.
The wastewater valve of above structure exists as following drawbacks: 1. since flow is to be controlled by micropore, and pass through waste water
The fluid media (medium) of valve often has scale and crystalline solid, be easy to cause the blocking of micropore；2. being caused since micropore sectional area is smaller
Fluid media (medium) hydraulic pressure is excessive, flow velocity is too fast, and then generated noise is larger.
Summary of the invention
It makes an uproar caused by a kind of reduction fluid media (medium) in view of the deficiencies of the prior art, the present invention intends to provide
Sound and the reduction possible wastewater valve with scale-deposit-preventing and silencing function of blockage of the micro orifice.
To achieve the above object, described the present invention provides the following technical scheme that including valve body, spool and executing agency
Valve body in be provided with the runner with water inlet and water outlet, annular partition, the annular are provided in the valve body
Runner is divided into positioned at center and with the inner flow passage of water outlet connection and around inner flow passage and outer with water inlet connection by partition
Runner, the annular partition are used as water cut off device towards the open-ended of spool, and executing agency's fixed valve body simultaneously drives
The mobile spool that constitutes of spool cooperates far from water cut off device or with water cut off device sealing, it is characterised in that: and it further include floating installation, it is described
Valve body is located at annular partition and the other end of water cut off device is provided with waste water hole with water inlet, and the floating installation floats
Seat, contact pin, floating barrier and buffer spring, the floating seat and valve spool be arranged and with spool synchronizing moving, it is described
Contact pin is fixed on floating seat and coaxially passes through waste water hole, and the gap of the contact pin periphery and waste water hole inner circumferential is used as to be situated between for fluid
The dynamic waste water gap of mass flow, the floating barrier and buffer spring are sheathed on contact pin, and the floating barrier is sliding along contact pin
It moves and closes the connection position of waste water hole and inner flow passage under buffer spring effect, the spool is in the case where executing agency drives
When closing water cut off device, floating barrier connection position far from waste water hole and inner flow passage under the pressure effect of fluid media (medium), and
It back and forth floats under buffer spring effect along contact pin, fluid media (medium) enters inner flow passage from waste water gap；The spool is in the machine of execution
When under structure driving far from water cut off device, the floating seat with valve spool extracts the contact pin on floating seat out waste water hole far from waste water hole,
Waste water hole is washed away by fluid media (medium).
By using above-mentioned technical proposal, by contact pin periphery and the gap of waste water hole inner circumferential as being flowed for fluid media (medium)
Waste water gap can expand the aperture of waste water, avoid aperture too small by scale and crystalline solid blocking and the excessive problem of noise, be used for
The floating seat of fixing plug pin is the component with spool synchronizing moving, the snaking movement that contact pin simulation pulls and pushes when spool periodically moves,
The possibility of accumulation of mud is further decreased, moreover, the floating barrier added, under the comprehensive function by hydraulic pressure and buffer spring,
Spool can back and forth float when closing water cut off device along contact pin, and floating movement can be used in buffering the big minor swing of hydraulic pressure, and water flowing is made an uproar
Sound can stabilization will not be become larger by influence of hydraulic pressure, in addition, water cut off device open when, waste water hole is in maximum stream flow state, makes waste water
Continuous erosion of the inner wall in hole by fluid media (medium), sufficiently prevents the possibility of scale buildup.
The present invention is further arranged to: the Plug pin patch bay is provided with protection ring around contact pin and floating barrier, described
Valve body is located at waste water hole and the connection position of inner flow passage is provided with the boss extended in protection ring.
By using above-mentioned technical proposal, due to smooth, the Cai Nengbao of the sliding cooperation of floating barrier to be guaranteed and contact pin
The floating sensitivity of floating barrier is demonstrate,proved, and then guarantees the buffering effect to hydraulic pressure, contact pin and floating barrier are carried out by protection ring
Protection, avoid in spool when leaving water cut off device contact pin and float by the fluid media (medium) of big flow impact and deformation, extend
Service life, the gap flowed due to being reserved for fluid media (medium) between protection ring and the side wall of inner flow passage, cannot will completely enclose,
Therefore boss is added in the connection position of waste water hole and inner flow passage, being further reduced contact pin and floating barrier directly can by what is impacted
Can, further prolong the service life.
The present invention is further arranged to: the spool is water retaining disk, and the water retaining disk is provided with slotting towards floating seat
Slot, the floating seat are provided with the inserted block composition floating seat of insertion slot and being linked for water retaining disk.
By using above-mentioned technical proposal, the cooperation of slot and inserted block keeps the assembly of water retaining disk and floating seat more convenient,
The mode that interference fit or fixing piece can be used keeps being linked for the two more stable.
