Description
Technical field
This utility model relates to a kind of vacuum components and parts, is specifically related to a kind of practical band from the split of hold down gag
Formula vacuum valve.
Background technology
Vacuum valve belongs to the standard vacuum components and parts that Vacuum Field uses in a large number, and existing vacuum valve is of a great variety, but
For narrow and small use space and mobile vacuum system, existing valve volume is relatively big, and damage of easily colliding with when system is carried.
In addition the vacuum valve structure of prior art is more complicated, and manufacturing cost is higher, and practicality is the strongest.
Therefore, necessary designing and developing a kind of reasonable in design on the basis of prior art, size is little, manufacturing cost
Low, it is particularly suited for small space and the vacuum valve of mobile vacuum system.
Summary of the invention
Goal of the invention: the purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of structure design is closed
Reason, practical, size is little, low cost of manufacture, is especially widely portable to the true of small space and mobile vacuum system
Empty valve.
Technical scheme: in order to realize object above, technical solution adopted in the utility model is:
A kind of band is from the split type vacuum valve of hold down gag, and it includes upper valve body, with upper valve body by under Flange joint
Valve body, upper valve body and lower valve body junction clip are fixed, and described upper valve body includes valve casing and the valve rod being arranged in valve casing,
Described valve casing side opening is provided with the flange for being connected with vacuum pump, and described lower valve body includes valve seat and is arranged in valve seat
Spool, together with the notch of described stem lower portion plugs together with the spool in lower valve body, can band movable valve plug by rotary valve rod
Upper and lower motion.
Preferably, above-described band passes through screw thread from the split type vacuum valve of hold down gag, described spool
The mode connected is arranged in valve seat, and lower valve body inner spool can be real with the valve base sealing face seal of lower valve body by thread mechanism
Now from compressing.
Preferably, above-described band is installed from the split type vacuum valve of hold down gag, described valve rod upper end
There is handwheel, by rotation hand wheel, can rotate by band ovable valve stem, it is thus possible to band ovable valve stem rotates in valve casing, and upper and lower motion, when
When upper valve body and lower valve body couple, together with the notch of stem lower portion plugs together with the spool of lower valve body, by rotary valve rod upper end
Handwheel can move up and down by band movable valve plug, thus realize the open and close of valve.
Band provided by the utility model is anchored on by screw is taken out from the split type vacuum valve of hold down gag, lower valve body
On Dewar vessel.
Lower valve body, when the split type vacuum valve of hold down gag is actually used, is first passed through spiral shell by the band that this utility model provides
Clench to be fixed in and be evacuated on container, then the flange of upper valve body and lower valve body is docked, and fixed by clip, then will be true
Empty pump is connected on the flange of valve casing side, when starting evacuation, rotates up upper valve body handwheel, and handwheel band ovable valve stem rotates,
And driving the spool in lower valve body to move upward, spool is lifted off a seat sealing surface, after exhausting vacuum, the hands being rotated down on valve rod
Wheel, lower valve body inner spool moves downward, and is pressed in sealing surface of seat, it is achieved valve closing, after exhausting vacuum, disassembles standard card
Hoop, can take off upper valve body.This utility model uses upper valve body and lower valve body Split type structure, lower valve body with from hold-down mechanism,
Due to upper valve body only when evacuation as the valve switch instrument of band vacuum pumping port, the most multiple lower valve bodies only can be equipped with one
Upper valve body, cost-saved.
Beneficial effect: the band that this utility model provides compared with prior art has from the split type vacuum valve of hold down gag
Advantages below:
The band that this utility model provides, from the split type vacuum valve of hold down gag, reasonable in design, carries during use
Close from compressing and open, practical, and size is little, low cost of manufacture, is especially applicable to small space and movement
The vacuum valve of formula vacuum system, has wide range of applications, and can overcome many deficiencies of existing vacuum valve.
