Embodiment
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate, it should be understood that following specific embodiment parties
Formula is merely to illustrate the utility model rather than limitation the scope of the utility model.It should be noted that make below in description
Word "front", "rear", "left", "right", "up" and "down" refer to the direction in accompanying drawing, and word " interior " and " outer " refer to respectively
Be directed towards or the direction away from particular elements geometric centers.
Antivoid valve, it is characterised in that comprising valve body, the valve body and valve seat are connected by bolts, valve body and valve seat
Between include sealing gasket, valve seat tundish contains positioning sleeve, and positioning sleeve tundish contains adjustment bolt, valve plate is included below positioning sleeve,
Valve plate is also adjusted bolt and passed through;Spring is adjacent to above positioning sleeve, and spring upper end is gland, and adjustment bolt end passes through gland
Its top is adjusting nut, and rotation adjusting nut can adjust the elastic force of spring, further adjustment valve plate and sealing surface of seat
Adhesive force.The substantive technique effect and its implementation process that the technical scheme at this place is played are as follows:Spiral shell is adjusted by rotating
Mother, further such that adjusting nut moves downward on bolt, move downward and be pressed further by gland, further gland can extrude
Spring so that spring is extruded the size of the adhesive force of elastic force is bigger, below further adjustment valve plate and sealing surface of seat, when
Vacuum is excessive in container, i.e., suction is excessive, when reaching default vacuum values, will cause valve plate and relative point of sealing surface of seat
From occurring space after relative separation, the gas of outside will enter the side of vacuum, until the closed container or system of connection
When vacuum values in pipeline are less than or equal to default vacuum values, valve plate and sealing surface of seat recover to be brought into close contact automatically;The knot
The effect of structure is when this structure, which is arranged on, to be required on closed container or system pipeline, to prevent vacuum is excessive to cause
Either system pipeline is inhaled deformation or damage to closed container.
The preferable installation site of this patent is:The valve body by with the flange on other closed containers or system pipeline
Coupled.
A protective cover on the valve seat, air-vent is included on the protective cover.The essence that the technical scheme at this place is played
Technique effect and its implementation process be as follows:Protective cover can be prevented the limbs of neighbouring staff when valve air inlet
Either outside object is sucked in closed container or vacuum system pipeline, causes personal injury or equipment breakdown.
The valve seat and valve body are positioned at interior.This place is the preferable installation site of this structure.
When this patent is arranged on outside, valve seat and the valve body vertical, thereon comprising rain cover, rain cover
Pass through clamp connection protective cover.The substantive technique effect and its implementation process that the technical scheme at this place is played are as follows:It is anti-
Canopy can rainwater-proof, when Sometimes When It Rains, can prevent rainwater from entering in valve and in closed container or system pipeline.
The horizontal arrangement of valve seat and valve body.This place can be a kind of preferable mounting means and structure, for example be arranged on
When on tank body side.
The air-vent is located on the side of protective cover, and protective cover does not have air-vent on end face.The technical scheme institute at this place
The substantive technique effect and its implementation process played is as follows:The structure at this place being capable of the vertical indoor feelings installed in no water
Under condition, rain cover can be pulled down, by air-vent side arrangement, this kind of structure is avoided that the debris smaller than air admission hole or other
Grain thing is fallen into protective cover, cause valve can not it is normally-open or close either open after suck the closed container of connection or be
In road under the overall leadership.
Comprising connection mounting hole below the valve body, mounting hole is internal thread, and closed container is bound up on using outer screw
Or on the flange of system pipeline.This place provides a kind of specific mounting structure so that this patent can be arranged on it by flange
On.
Generally speaking, antivoid valve is applied to the equipment for producing vacuum, to prevent equipment from deforming or damaging because of vacuum
Evil, it is capable of the safety of protection equipment.When the vacuum values in equipment exceed permissible value, antivoid valve would automatically turn on,
Air is sucked, when the pressure in equipment returns to defined pressure, antivoid valve can close automatically.
Products characteristics:
Switch is rapid, and discharge capacity is big.
Rain-proof design protection, it is easy for installation.
It is simple in construction, it is aesthetic in appearance, safe to use.
It is excellent using the action of the positioning sleeve spaced motion part of guiding, sealing property.
