Description
Technical field
The utility model relates to fluid control device, relates in particular to a kind of partition fluid upstream and downstream, prevents downstream to be back to the isolating valve structure of upstream.
Background technique
The major reason that food, pharmaceutical field Accident due to quality take place frequently is exactly cross pollution, particularly blow-off line, condensate drain pipeline, towards blowdown, condensate drain arm because of supervisor between pressure reduction, the waste gas often polluted or waste liquid pour in down a chimney in the supervisor being in asepsis or preparing tank from arm, thus cause secondary pollution.
The valve of existing use mainly contains spring pressuring plate formula and blocked flake type safety check (or one-way valve).
See Fig. 1, spring pressuring plate formula formula safety check adopts spring to push down the control that gasket seal reaches fluid; It comprises valve body 5, import 1, outlet 4, catch 2 and spring 3.The defect of this structure is the pressure needing to overcome spring, so when pipeline or container inner fluid little when (deadweight) just do not overcome the pressure of spring, thus cause can not emptying, and the liquid of delay just may cause microbial contamination for a long time.
See Fig. 2, blocked flake type safety check is metal sealing form, and catch is hung vertically in inside valve body.It comprises valve body 9, import 6, outlet 8, catch 7.This structure needs level to install, its defect be when install upstream tilt time, just can not emptying; Just can not seal when installing inclined downstream, causing upstream and downstream to be in pass-through state.
Model utility content
For the problems referred to above, the utility model provides a kind of isolating valve structure, to solve the problem that valve body of the prior art effectively can not cut off upstream and downstream.
To achieve these goals, the technical solution of the utility model is as follows:
Isolating valve structure, it is characterized in that, comprise valve body, baffle plate valve inner cavity volume being divided into two, left and right is provided with in described valve body, described valve body is provided with entrance and exit, described entrance and exit is separately positioned on the both sides of baffle plate, and the level height of entrance is higher than the level height of outlet, and entrance and exit place is respectively arranged with honeycomb duct; The outlet end of described inlet honeycomb duct is provided with the catch that upstream fluid can be pushed open by self gravitation or flow velocity; Described baffle plate is connected with valve body, and defines a passage gaps between the lower end of baffle plate and valve body, and the lower end surface of baffle plate is lower than the outlet of valve body.
In the utility model, the outlet end of described inlet honeycomb duct is tilting entry end, and described catch tilting is installed, and catch upper end thereof, lower end is free end.Further, metal sealing form is adopted between described catch and the outlet end of inlet honeycomb duct.
In the utility model, described valve body comprises a valve gap, and valve body and valve gap are split-type structural, are provided with sealing gasket between valve body and valve gap.Further, the upper end of baffle plate and valve gap form sealing state.
The utility model effectively can cut off the connection in upstream and downstream, especially for the industry that health levels necessitate is high, the upstream material that turbidity test are very high often, need to discharge after pipeline or cleaning container, and ensure the hygienic requirements equal with product (as food or medicine), the downstream blow-off line that pollution index is very high often or directly identical with air, the secondary pollution effectively protected cleaned up-stream system and may cause is the emphasis of health industry; The present invention can effectively control the pollution that releasing system causes.
The utility model feature has:
1. adopt metal sealing form between catch and the outlet end of inlet honeycomb duct, be arranged on entry end with the angle tilted, even if having certain inclination when installing, also can play effective seal action; The fluid of upstream is pushed catch open as water or gas and is flowed out, and when outlet has fluid to recoil, catch just effective sealing, prevents from entering upstream.
2. baffle plate and valve body are welded as a whole, but lower end surface is again lower than the outlet of valve body, when more than flow volume in valve body time (liquid level with outlet maintain an equal level), just define the state of water seal.When outlet is in opening-wide state, the air in downstream defines isolated under the effect of water seal with upstream, and compensate for catch and may there is poorly sealed close risk.
3. valve body inlet adopts with outlet the form misplaced up and down, can ensure that the fluid of downstream can not enter in valve body (pipeline of downstream drain or trench, all lower than the outlet of valve body).
The detailed description and obtaining that feature of the present utility model can consult the graphic and following better mode of execution of this case is well understood to.
Accompanying drawing explanation

Fig. 2 is the schematic diagram of blocked flake type safety check.
Fig. 3 is structural representation of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below in conjunction with specific embodiment.
See Fig. 3, isolating valve structure, comprises entrance 11, honeycomb duct 12; Catch 13, baffle plate 14, outlet 15; Valve body 16, sealing gasket 17, valve gap 18.Wherein, valve body 16, valve gap 18, baffle plate 14, catch 13, honeycomb duct 12 all adopt stainless steel.
Valve body 16 and valve gap 18 are split-type structural, and sealing gasket 17 is arranged between valve body and valve gap.
Valve inner cavity volume is divided into two, left and right by baffle plate 14.
Valve body is provided with entrance 11 and outlet 12, entrance 11 and outlet 12 are separately positioned on the both sides of baffle plate, and the level height of entrance is higher than the level height of outlet, entrance 11 adopts with outlet 15 form misplaced up and down, can ensure that the fluid of downstream can not enter in valve body.Entrance and exit place is respectively arranged with honeycomb duct 12; The outlet end of inlet honeycomb duct is provided with the catch 13 that upstream fluid can be pushed open by self gravitation or flow velocity; The outlet end of inlet honeycomb duct is tilting entry end, and catch tilting is installed, and catch upper end thereof, lower end is free end.Metal sealing form is adopted between catch and the outlet end of inlet honeycomb duct.The fluid of upstream is pushed catch 13 open as water or gas and is flowed out, and when outlet has fluid to recoil, catch just effective sealing, prevents from entering upstream.
Define a passage gaps between the lower end of baffle plate and valve body, and the lower end surface of baffle plate is lower than the outlet of valve body.When more than flow volume in valve body time (liquid level with outlet maintain an equal level), just define the state of water seal.When outlet is in opening-wide state, the air in downstream defines isolated under the effect of water seal with upstream, and compensate for catch and may there is poorly sealed close risk.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
