Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
Embodiment 1
As shown in Figure 1, including valve body 1, spool 2, bullet the utility model discloses a kind of pressure reducing valve with inverse-stopping functions
Property body 3, support base 4, water inlet lid 5, outflow cover for water 7 and check sheet 8, valve body 1 be in lead to the cylindrical work of structure, inside valve body 1
It is provided with partition 9, circular through hole is offered on partition 9, offers gas vent 10 on the valve body 1 of 9 lower section of partition, support base 4 is set
It sets in the top of partition 9, the middle part that the outside of support base 4 is provided with lid 5 of intaking into water lid 5 is provided with gasket 6, in spool 2
Portion offers water stream channel 12, and spool 2 passes through in the circular through hole insertion support base 4 on partition 9, shape between spool 2 and valve body 1
At air chamber 11, elastomer 3 is nested on spool 2, and the lower section of spool 2 is arranged in outflow cover for water 7, and the bottom center of outflow cover for water 7 is set
It is equipped with check sheet 8.
Spool 2 includes valve core and valve core case, and valve core case is round slot structure, and valve core is arranged on valve core case, valve
Water stream channel 12 is offered in the middle part of core, elastomer 3 is spring, is nested on valve core, the circular trough of valve core case is arranged in
In structure.
Support base 4 is " convex " type structure, and upper end offers the circular through hole isometrical with partition 9, and lower end offers circle
Connected in star intakes and forms water flow gap 13 between lid 5 and the upper end of valve core.
Several flowing holes 14 is offered on water inlet lid 5 and outflow cover for water 7.
As shown in Figure 2,3, annular groove 15 is offered on spool 2, support base 4 and valve body 1, on spool 2 and support base 4
Annular groove 15 realizes that the sealing with 1 inner cavity of valve body is installed by setting sealing ring 16 or y-type seal ring 17, the annular on valve body 1
Slot 15 realizes that the sealing with pipe laying inner cavity is installed by setting sealing ring 16 and y-type seal ring 17.
Depressurize working principle:
As shown in figure 4, in the initial state: water is flowed into from water inlet end, is flowed by the water stream channel 12 among spool 2
The bottom position of spool 2, hydraulic pressure have a upward active force to spool 2.There is a precompression F to elastomer 3 during installation,
It is also not enough to that spool 2 is pushed to move when hydraulic pressure is less than F, spool 2 is maintained at original state.
In decompression state: hydraulic pressure increases, the precompression for being greater than elastomer 3 until acting on the hydraulic pressure of bottom end of spool 2
F, spool 2 up move under the action of water pressure, and the hydraulic pressure for passing through water stream channel 12 reduces, and reach effect of easing stress, air chamber
Air in 11 is discharged through gas vent 10.
When in off position: when the product of pressure reducing valve connection is blocked, or being closed, spool 2 is under the action of water pressure
It up moves, until being closed, the pressure of water outlet is stablized in some value P, to ensure that hydraulic pressure suffered by pipeline and product exists at this time
In safe range.
Non-return principle:
As shown in figure 5, in the initial state: when not crossing water, check sheet 8 is in normally off, and check sheet 8 is fitted in water outlet
On 7 end face of lid.
In non-non-return state: water is flowed into from water inlet end, reaches outflow cover for water 7 by the water stream channel 12 among spool 2
When flowing hole 14, check sheet 8 is rushed curved by water flow, and the flowing hole 14 on outflow cover for water 7 is opened, water outflow.
In non-return state: check sheet 8 is initially in off state.Ponding when reverse ponding, such as in washbasin will flow
When entering into pipeline, check sheet 8 is forced on 7 end face of outflow cover for water under the action of water pressure, reaches sealing effect, prevents ponding inverse
Stream.Hydraulic pressure is bigger, and check sheet 8 is pressed tighter with 7 end face of outflow cover for water, and sealing effect is better.
