Abstract
The utility model provides a kind of check-valves, it is characterised in that: check-valves is mainly made of upper valve body, lower valve body, membrane module, washer, hex bolts, nut；There is membrane module in upper lower valve body, is main working parts, air-flow one-way air inlet can be made, air inlet can not be returned, play the role of non-return air-flow；The utility model will be appreciated that, good airproof performance, install convenient, maintenance it is simple, at low cost the advantages that.
Description
Technical field
It is main to be applicable in the utility model relates to a kind of one of transportation system that novel pneumatic conveying uses check-valves
In the air-transport system of various industrial powders or granular material, injection system and conveying in blowpipe road.
Background technique
It is mostly Pneumatic butterfly valve, electric butterfly valve etc. in the valve that current powder pneumatic conveying industries use.Pneumatic conveying
It is required that valve tightness is good, simple and convenient, durable；Conventional valves leakproofness is poor, maintenance difficult, not easy to operate.Cause
This traditional valve uses in the air-transport system of powder, and drawback is more.
Utility model content
In order to overcome conventional valves in industrial powder air-transport system, maintenance difficult poor using leakproofness, be not easy
The problem of operation, the utility model provide a kind of dedicated check-valves of powder pneumatic transportation system.The utility model and conventional valve
Door is compared, and has many advantages, such as that good airproof performance, install convenient, maintenance are simple.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of check-valves, it is characterised in that: check-valves mainly by upper valve body, lower valve body, membrane module, washer, hex bolts,
Nut composition；Main body of the valve body as entire check-valves, centered on the top dome of inflatable dome valve, in upper valve body, lower valve body
It is equipped with membrane module in inner cavity, washer and membrane module group is integral sets between upper valve body, lower valve body plays sealing and dust-proof work
With；Upper valve body, lower valve body are coupled by hex bolts, nut；For main working parts, air-flow one-way air inlet can be made, it can not
Air inlet is returned, non-return air-flow is played the role of；
Wherein, the membrane module two sides of the check-valves are equipped with washer；
Wherein, the upper lower valve body of the check-valves is casting, reduces cost；
Wherein, the rubber membrane in the membrane module of the check-valves is customization rubber, and hardness is higher than other General Purpose Rubbers.
The utility model will be appreciated that, good airproof performance, install convenient, maintenance be simple, without electrical control, at low cost etc.
Advantage.
