Abstract
A cam type blocking valve comprises a valve core and a valve body. The valve core is in a cam shape, a locking partition plate is arranged inside the valve body, and the edge of the valve core is in sliding connection with the locking partition plate. The middle of the valve core in the cam shape is a channel, two ends of the valve core is provided with a superior arc end and an inferior arc end, and the superior arc end is a locking end. Due to the surface contact, the abrasion is small, air locking effect is good, service life is long, and leakage is avoided in an inner switching-over structure. The cam type blocking valve adopts unique cam type inner structure design and uses a switch of a cylindrical-surface eccentric rotating control valve to ensure that the blocking valve is capable of being tightly closed and opened, the inner switching-over structure is free of leakage, and the surface contact enables the service life to be prolonged. The cam type blocking valve is used for the air locking and cutting off of a dry ash processing system, provides choices in various ways including manually-operated, power-driven, pneumatic and hydraulic ways for users, can fully replace a gate valve and a dome valve which are widely used in the market, and has good market prospects.
Description
Technical field
The utility model relates to a kind of cam-type blocking valve, is a kind of of blocking valve.
Background technology
The blocking valve of prior art is varied, as:
One, application number: 01263038.1 applying date: 2001-09-29 discloses the straight-though high temperature lock gas ash-valve of a kind of troilite, zinc ore, gold sand acid making system; It is made up of valve housing, rotating shaft, rotor; Rotating shaft is provided with in the valve housing, and the one of which end stretches out valve housing and links to each other with driver train through sprocket wheel, and rotor is made up of axle sleeve and a plurality of radially-arranged strip blade; Rectangular distribution is connected with a plurality of strip blades on the outer wall of axle sleeve; The axle sleeve of rotor is sleeved in the rotating shaft, and the position of respective rotor is provided with inlet point on valve housing top, and the position of respective rotor is provided with discharging opening in its underpart; Valve housing is the cavity body than large space; Integral body is connected with two circular end plate respectively at the two ends of the axle sleeve of rotor and each strip blade thereof, constitutes the multi-cavity type rotor, in valve housing, is connected with its length direction charging sealing funnel identical with each strip blade of extending at the inlet point end opening; The base, both sides of this charging sealing funnel has an arc limit respectively, and the width on arc limit is not less than the distance between the outer rim of adjacent two blades of rotor.
Two, application number: the 01229375.X applying date: 2001-07-02; Disclose a kind of gentle firm dual rotor feeding blocking valve, it is characterised in that is equipped with flex rotor in the upper valve body, and its outlet is connected through bolt seals with the import of following valve body; In the valve body rigid rotor and end face adjustment dish are being housed down; Three through holes are arranged on the following valve body perisporium, and its top is that powder import, bottom are that powder outlet and top, left side are the lower pumping mouth, and the bottom of valve body is connected with nozzle down.The utility model is novel in design, compact conformation is reasonable, energy consumption is low, reliability is high, can guarantee the production long-time running, has practical reference value.
Application number: 200920181125.3 applyings date: 2009-12-11 discloses a kind of flexible blocking valve, comprises valve body and with valve body and tremie pipe bonded assembly attaching parts, and said valve body is the cylindrical shell of the both ends open processed by flexible material.The utility model is owing to adopted the rubber flexible valve body; The negative pressure that can make full use of in the duct cyclone tremie pipe realizes that the valve body automatic open close unloads ash, need not mechanical drive, the dust pollution that causes because of driving device is stuck can not occur; And it is easy to operate; Have advantage cheap, that the replacement cycle is long, air-tightness is good, collects the high advantage of dust efficient.
Three, application number: 02219396.0 applying date: 2002-03-16 discloses a kind of vacuum lock air valve, comprises upper valve body, following valve body and valve bonnet, and pelvic cavity is arranged in the upper valve body; Ball sealer is arranged in the pelvic cavity, and the pelvic cavity below is equipped with centre pipe, and following valve body has a bearing; Sleeve is installed on the bearing, has ball hole and centre pipe to communicate in the middle of the pelvic cavity, the ball sealer push rod is arranged in the centre pipe; Centre pipe lower end and sleeve socket, sleeve outer wall is fixed with spring plank; Between upper valve body, the following valve body spring reset mechanism and elastic telescopic joint are installed.When the valve body upper surface receives loading vertically downward and is compressed to when a certain amount of, valve is promptly opened, and when load disappeared, valve was a locking.Because the performance that undoes the lock automatically of the utility model, make the mobile vacuum that leaf-type vacuum filter is such, broken away from the burden of vacuum trombone slide, operate more automation, more can adapt to the production operation needs of Large Titanium white powder device.
In going out ash system, left not blocking valve.Widely used in the market have gate valve and a dome valve etc.Gate valve is prone to stifled ash, can cause ash to external leakage after the wearing and tearing, and contaminated environment, but inexpensive still are being widely used on the market.Dome valve belongs to inner and switches, outside no leak, but because its structural principle; Determined an awl mouthful contact wire to cause irregular wear easily, so air locking is bad, the dome valve contact position that has adds uses sealing member; Though solved sealing problem; But under worst hot case, sealing member is easy to ageing failure, and price is more expensive.
The utility model content
For addressing the above problem, I have designed a kind of cam-type blocking valve.
The purpose of the utility model is to realize through following technical scheme:
The cam-type blocking valve comprises spool and valve body, and said spool is cam-like; Be provided with the locking dividing plate in the valve body, the edge of spool and said locking dividing plate sliding block joint are passage in the middle of the spool of cam-like; Two ends have a major arc end and a minor arc end respectively, and said major arc end is the locking end.
I combine the characteristics of these two kinds of shutoff doors, have designed the cam-type blocking valve, and this valve adopts the flipped form of dome valve, utilize the switch of the eccentric rotary control valve in the face of cylinder, guarantee that equipment closes extremely, beats to such an extent that open.Owing to be the face contact, so it is little to wear and tear, lock gas is effective, long service life, and inner switching construction is guaranteed no leak.
This product adopts unique cam-type inner structure design, uses the switch of the eccentric rotary control valve in the face of cylinder, guarantees that equipment closes extremely; Beat to such an extent that open, intra is guaranteed no leak, and long service life is guaranteed in the face contact; The lock gas and the partition that are used for the dry ash disposal system; Possess manual, electronic, pneumatic, the various ways of surging confession user selection, can replace widely used gate valve and dome valve on the market fully, have extensive market prospects.
