Description
Technical field
The present invention relates to a kind of fast opening blind due in petroleum, natural gas, chemical pipeline more particularly to a kind of pintongs cards
Hoop formula fast opening blind and application method.
Background technique
A large amount of pressure vessel or pipeline are used in the industries such as natural gas, chemical industry, petroleum, metallurgy, such as filter is received
The equipment such as service cylinder, separator, heat exchanger, need irregular opening and closing, wherein fast opening blind is exactly to be used for this kind of pressure
On the circular open of hydraulic piping or pressure-vessel and it is able to achieve a kind of special machinery quickly opened and closed, with " west
Gas east is defeated " implementation of engineering, the demand of the development of combustion gas, large-diameter fast open blind plate is more and more, thus to the structure of the product,
The requirement of sealing performance, security reliability and operating function etc. is higher and higher, also increasingly increases to the research of fast opening blind
More, fast opening blind is in the end of bearing pipe or container, needs irregular switching motion, thus opens and closes to it convenient and reliable

Existing horizontal fast opening blind mainly includes horizontal three valves clip fast opening blind and horizontal two valves clip fast opening blind.
The structure of horizontal three valves clip fast opening blind as shown in Figure 1, its dependency structure Publication No. " CN2634245 ",
There is disclosure in the patent of " CN2627333 " " CN203730749U ", nuclear structure is to include three clips, by setting
Drive three clips to be opened and closed in the screw structure on top, so to blind plate lid carry out it is locked or release it is locked, wherein
There is a clip to be located at bottom, needs the cooperation of other two clip to carry out the lifting of bottom clip, for high in heavy caliber
For the horizontal three valves clip fast opening blind of pressure, the clip positioned at bottom is heavier due to being self-possessed, and will appear when closing
Promote situation not in place, influence sealing effect, and if things go on like this, due to three clips be all it is mutually matched, in theory
On, each clip should move in place during operation, but the clip of bottom is since there are positions for self-weight factor
Deviation will affect service performance, or even damage so going down for a long time.
The structure of horizontal two valves clip fast opening blind is as shown in Fig. 2, its nuclear structure is to include two symmetrically arranged
Annulus, the top and bottom of two annulus are connected by screw structure, by rotational lead screw come so that annulus carries out opposite direction
Separation or engagement, due to being two annulus, when switch, stroke is larger, and then the demand to space is high, and this
Kind sealing structure performance is poor, in addition, needing simultaneously to rotate the lead screw of upper and lower two sides when operation, to synchronism
Requirement it is very high, operation difficulty is high, inconvenient to use.
