Description
Technical field
The utility model is related to industrial chemicals processing technique field, and in particular to a kind of liquid and air check valve device.
Background technology
Industrial chemicals species is a lot, has many uses.Chemicals has as many as 500~7,000,000 kinds in the whole world, commercially goes out
Sell circulation more than 100,000 kinds, and also have the new chemicals of kind more than 1000 to come out every year, industrial chemicals when being processed,
When carrying out special preparation, it is necessary to the liquid to part flowing be blown using dry gas, so as to realize in gas
In mix band partially liq and carry out follow-up special processing, traditional working method is to use water to rush pump constantly to be circulated liquid
Flowing, is then passed through after drying of the opposite side by using drying machine progress gas, realizes work, but this equipment is being used
When, if stopped using, liquid substantial amounts of can be back to dryer inner along dry gas pipeline, so not only can be to normal
Drying machine cause certain damage, while can also moisten dry gas, influence subsequently be used.
Utility model content
Technical problem to be solved in the utility model is that offer is a kind of simple in construction, and plugging effect is obvious, user
Just liquid and air check valve device.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of liquid and air check valve device, main body are a sealed tank body, it is characterised in that：Described tank body upper end one
Side has been passed through a flue, and described tank body lower end side has been passed through in the middle part of a liquid line, described tank body and has been provided with a separation
One annulus is installed in the middle part of plate, described demarcation strip, described sleeve inner be provided with one can in sleeve on move down
A ball float is connected with the top of dynamic Hollow wrap core, described Hollow wrap core, the upper end side wall of described Hollow wrap core is provided with
Intensive through hole, described ball float upper end is provided with a circle sealing ring, and described Hollow wrap core upper end is connected with a drawstring, described
Demarcation strip upper end be provided with a crossbeam, described drawstring is fixed on crossbeam through sleeve and afterbody；
The bottom inside of described sleeve is provided with a barrier circle, and described Hollow wrap core top outer is provided with circle extension
Ring, it is to avoid Hollow wrap core comes off in sleeve, safer；
The bottom of described sleeve is provided with a spacing collar, is used in combination with sealing ring, and sealing is stronger；
The utility model is when in use：After equipment is stopped, liquid is back to tank interior, continuous hydrops by liquid line
Afterwards, ball float is floated, ball float drives Hollow wrap core, and motion is after sleeve bottom is blocked upwards, you can；
The beneficial effects of the utility model are：The utility model is novel in design, simple in construction, is made using the buoyancy of ball float
With realizing the backflow closure of liquid, it is to avoid while liquid backflow causes equipment damage, it is ensured that the quickness and high efficiency of processing
Performance, improves production efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
The enlarged diagram that Fig. 2 is A in Fig. 1.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figure 1 and Figure 2, a kind of liquid and air check valve device, main body is a sealed tank body 1, the upper end one of tank body 1
Side has been passed through a flue 2, and the lower end side of tank body 1 has been passed through a liquid line 3, and the middle part of tank body 1 is provided with a demarcation strip 14, separated
The middle part of plate 14 is provided with a sleeve 4, and sleeve 4 is internally provided with a Hollow wrap core 5 that can be moved up and down in sleeve 4, hollow
The top of set core 5 is connected with a ball float 6, and the upper end side wall of Hollow wrap core 5 is provided with intensive through hole 7, and the upper end of ball float 6 is provided with
One circle sealing ring 8, the upper end of Hollow wrap core 5 is connected with a drawstring 9, and the upper end of demarcation strip 3 is provided with a crossbeam 10, and drawstring 9 passes through set
Cylinder and afterbody be fixed on crossbeam 10, so setting after, after equipment is stopped, liquid is back in tank body 1 by liquid line 3
After portion, continuous hydrops, ball float 6 is floated, ball float 6 drives Hollow wrap core 5, and motion is after the bottom of sleeve 4 is blocked upwards, i.e.,
Can, the bottom inside of sleeve 4 is provided with a barrier circle 11, the top outer of Hollow wrap core 5 is provided with a circle link 12, it is to avoid sky
Heart set core 5 comes off in sleeve 4, and safer, the bottom of sleeve 4 is provided with a spacing collar 13, and being engaged with sealing ring 8 makes
With sealing is stronger；
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
