Abstract
Provided is a novel pressurizing sealing ball valve. The novel pressurizing sealing ball valve is mainly characterized by comprising a sealing clearance aligning device, a valve core hemispheroid adjusting mechanism and a deposited dust clearing device. The sealing clearance aligning device is composed of a valve body, a sealing assembly, a tension bolt and a compression bolt and can directly align sealing clearances. The valve core hemispheroid adjusting mechanism is connected by a valve cover, an adjusting bolt, a locating shaft, a valve core hemispheroid and a snap spring and can adjust the moving positions of the valve core hemispheroid, and the deposited dust clearing device is connected with a high-pressure air source to directly clear deposited dust inside the valve body. The novel pressurizing sealing ball valve has the advantages of conveniently assembling, maintaining and replacing sealing rings, conducting real-time alignment on the sealing clearances, prolonging the service life of the sealing rings, and reducing production, maintenance and use cost of products.
Description
Technical field
The present invention relates to a kind of valve technology, belong to valve mechanical technique leader territory.
Background technique
Existing a kind of pressurizing sealing half-ball valve that is applied to the material blanking of blast furnace pulverized coal ironmaking system and bearing pipe, patent No. ZL032639341, the sealing of this ball valve is by seal ring, positioning ring and supporting ring, be clipped between valve gap and valve body, with the spool hemisphere sealing pair that partners, when valve closes seals, by the inflation inlet on the valve body seal ring is inflated, seal ring is close to the sphere of spool, valve closing because of compressive deformation.When valve need to be opened, the gas in the releasing sealed circle, seal ring elastic recovery and spool sphere broke away from the formation gap, then drive spool and turn to opening state, valve opening.This valve also exists larger defective: the 1st, and seal clearance and valve element position are difficult to be detected and levelling, and therefore often or spool hemisphere position skew improper because of the gap causes leakage or seal ring to decrease ring.The 2nd, the sealed member installation, maintenance is cumbersome, and seal ring is changed difficulty.The 3rd, cavity has dust stratification not to remove, and affects working life.Because the existence of these defectives has greatly affected effect and the cost of product, therefore be badly in need of a kind of improved technology and solve existing problem in the prior art.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of cleaning device of seal clearance levelling device, spool hemisphere positioning regulating mechanism and dust stratification, there is assembling simple, easy to maintenance, in real time regulating sealing gap and spool hemisphere position, location, in time remove valve body inner product ash, the commutation of valve cleaning.
Technological scheme of the present invention is:
Novel pressure sealing ball valve, comprise seal clearance levelling device, spool hemisphere controlling mechanism and dust stratification cleaning device, described seal clearance levelling device is by valve body, seal assembly, turnbuckle, the hold-down bolt nuts and washers forms, described valve body is to use Plate Welding, 4-6 M16 screw and 4-6 φ 16 through holes are arranged in the upper-end surface of valve body, at the in-built hold-down bolt in M16 hole, at φ 16 in-built turnbuckles, turnbuckle is connected with seal, seal assembly is lifted in the valve body, described seal assembly is by seal, positioning ring and seal ring connect to form, seal has pore and air drain on it, pore communicates with the enterprising pore of valve body, and air drain communicates with pore on the positioning ring, and pressurized gas enters in the Seal cage easily.
Novel pressure sealing ball valve, comprise spool hemisphere controlling mechanism, described spool hemisphere controlling mechanism is connected to form by valve gap, adjusting bolt, positioning shaft and spool hemisphere and jump ring, the described valve gap therein heart has tapped hole, the adjusting bolt the other end is screwed in the tapped hole, rotates adjusting bolt and can make the running fix of spool hemisphere.
Novel pressure sealing ball valve comprises the dust stratification cleaning device, and described dust stratification cleaning device is at the valve gap upside air vent connector to be housed, air vent connector is connected with high-pressure air source, the other end at air vent connector is equipped with rotating sprinkler, is used for the winding-up pressurized gas, removes valve body inner product ash.
Beneficial effect of the present invention: seal assembly is installed by the valve body side opening, directly be assemblied in the valve body, use seal clearance levelling device and the directly measurement of spool hemisphere positioning regulating mechanism, regulating sealing gap and location spool hemisphere, there is assembling simple, seal ring replacing, easy to maintenance, and can real-time regulating sealing gap and valve element position.The dust stratification cleaning device is removed valve body inner product ash, guarantees that the valve cleaning opens and closes commutation, prolongs seal ring working life, has reduced production, maintenance and the user cost of product.Dismounting is difficult and cause the defective such as seal ring damage because of reasons such as dust stratifications when having overcome seal clearance and being difficult for levelling, maintenance.
