Description
Technical field
The utility model relates to diaphragm pump field, more specifically, relates to the flow guide structure on a kind of diaphragm pump.
Background technique
The fluid chamber that diaphragm pump comprises the pump housing and is connected with the pump housing, fluid chamber is provided with the inlet valve sucked for medium (being generally water or other fluid medium) and the drain valve of discharging for medium.Adjacent one group of inlet valve and drain valve interconnect.Often organizing diaphragm inlet valve all being arranged and seals it, described drain valve has many groups, and many group drain valves share a diaphragm and seal it.
Said structure easily produces collision due to the medium of discharging in the drain valve outlet of each drain valve thus produces mixed flow, adds the time that medium is discharged, and easily makes diaphragm pump produce noise in running.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of water pump flow guide structure.
The utility model is achieved through the following technical solutions: a kind of water pump flow guide structure, comprise the pump housing and the fluid chamber being arranged on pump housing front end, described fluid chamber comprises the drain valve that at least two groups supply the inlet valve of medium suction and at least two groups to discharge for medium, described inlet valve and described drain valve are provided with the black box to its sealing, often organize described inlet valve and comprise water-inlet cavity and compression chamber, often organize drain valve and comprise drain valve entrance and drain valve outlet, described compression chamber is communicated with drain valve entrance, arranges the flow apron separated between described drain valve.
In technique scheme, described flow apron wooden partition camber.
The utility model has following beneficial effect: the outlet of the drain valve of described drain valve is separated by flow apron by the utility model mutually, when the high-velocity fluid of discharging from drain valve outlet is discharged, first after the flowing of flow apron wooden partition, adjacent drain valve outlet is entered again, avoid the fluid of discharging from each independently drain valve outlet and impact, mixed flow mutually occur, thus reduce diaphragm pump noise operationally.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
See Fig. 1 to Fig. 8, comprise the pump housing 1 and the fluid chamber 2 being arranged on the pump housing 1 front end, described fluid chamber 2 comprises the inlet valve 10 sucked for medium and the drain valve 11 of discharging for medium, described inlet valve 10 is provided with the first black box 3 of its opening of sealing, described first black box 3 comprises guide pillar 30, described guide pillar 30 slides and is arranged in described inlet valve 10, described guide pillar 30 lower end is provided with a circle flange 31, this flange 31 arranges an O type circle 32, also comprise the first Returnning spring 33 be set on described guide pillar 30, described first Returnning spring 33 one end leans the screw capping 34 being arranged at described guide pillar 30 upper end, the other end is defined and fluid chamber 2 inwall.Namely, by the effect of the first Returnning spring 33, a described O type circle 32 is made to have the trend sealing described inlet valve 10, linear sealing is sealed into due to an O type circle 32 and inlet valve 10 opening, therefore sealing area is substantially reduced, due to the reduction of sealing area, the impurity such as fine sand particle are difficult to the delay of the place of sealing again and are convenient to fine sand particle etc. discharge from opening smoothly.
The opening of described inlet valve 1 is provided with guide pillar support 35, described guide pillar support 35 is offered with pilot hole, described guide pillar 30, by described pilot hole, is provided with the assembly wall 36 that encloses upwards side direction extension around described pilot hole.When installation the first Returnning spring 33, first the screw capping 34 the first Returnning spring being inserted in guide pillar 30(now guide pillar 30 is not installed), described first Returnning spring 33 one end is plugged and described mounting arm 36, it is made to lean described guide pillar support 35, then being screwed into screw capping 34 in guide pillar 30 upper end makes itself and described first Returnning spring 33 the other end lean, and now the first Returnning spring 33 is compressed between screw capping and guide pillar support 35.And due to the leading role of guide pillar support 35 pairs of guide pillars 30, make it when straight skidding, the component of substantially horizontal can not be produced.
Described inlet valve 10 is provided with three groups, and often organize inlet valve 10 and comprise water-inlet cavity 10a and compression chamber 10b, corresponding described drain valve 11 is also provided with three groups, often organizes drain valve 11 and comprises drain valve entrance 11a and drain valve outlet 11b.Compression chamber 10b between one group of adjacent inlet valve 10 and drain valve 11 and drain valve 11a entrance are interconnected.The medium of namely discharging from described compression chamber 10b only flows in the drain valve outlet 11b of the drain valve 11 be adjacent, and is provided with second black box often organizing on described drain valve 11, is separated from each other setting between described second black box of each group.When the second black box on wherein drain valve 11 described in a group lost efficacy due to blocking, all the other two groups all can normally play a role, and never lost efficacy two groups of media of discharging between inlet valve and drain valve have and have certain impact power, certain probability is had to wash out the foreign matter on the second black box being stuck in inefficacy place.Thus recover the function of inefficacy place.
Described second black box 5 comprises the sealed plunger 50 be movably set in drain valve 11 and the 2nd O type circle 54 arranged on described sealed plunger 50, described sealed plunger 50 one end is provided with spring seat 51, described sealed plunger 50 the other end is provided with guide plate 52, described spring seat 51 is provided with the second Returnning spring 53, and described second Returnning spring 53 makes described 2nd O type circle 54 have the trend sealing described drain valve 11.Described guide plate 52 is two plate bodys arranged in a crossed manner, and each plate body and drain valve 11 sidewall contact with each other, and be convenient to sealed plunger 50 when drain valve 11 slippage, it can not produce the skew of substantially horizontal.
Between described drain valve 11, flow apron 4 is set, described flow apron 4 is curved, by described flow apron 4, the drain valve of described drain valve 11 outlet 11b is separated mutually, when the high-velocity fluid of discharging from drain valve outlet 11b is discharged, first after the flowing of flow apron wooden partition, adjacent drain valve outlet is entered again, avoid the fluid of discharging from each independently drain valve outlet and impact, mixed flow mutually occur, thus reduce diaphragm pump noise operationally.
