Abstract
A novel pressurized sealing ball valve is mainly characterized by comprising a sealing gap aligning device, a valve core hemisphere adjusting mechanism and a dust removing device; the sealing gap aligning device is formed by a valve body, a sealing assembly, a tension bolt and a compression bolt and used for aligning sealing gaps directly; the valve core hemisphere adjusting mechanism is formed by a valve cover, an adjusting bolt, a positioning shaft, a valve core hemisphere and a snap spring through connection and used for adjusting the moving position of the valve core hemisphere; the dust removing device is connected with a high pressure air source and used for removing dust in the valve body directly. According to the novel pressurized sealing ball valve, the assembly, maintenance and sealing ring replacement is convenient, real-time alignment can be performed on the sealing gaps, the service life of a sealing ring is extended, and the production, maintenance and use cost of products is reduced.
Description
Technical field
The utility model relates to a kind of valve technology, belongs 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 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 break away from the formation gap, then drive spool to turn to opening state, valve opening.This valve also exists larger defect: 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 gap causes leakage or seal ring to damage 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 defects has greatly affected effect and the cost of product, so be badly in need of existing problem in a kind of improved technology solution prior art.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model 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 the location spool hemisphere position, remove in time valve body inner product ash, the clean commutation of valve.
The technical solution of the utility model 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 the in-built turnbuckle of φ 16, turnbuckle is connected with seal, seal assembly is lifted in 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, air drain communicates with the pore on positioning ring, pressurized gas enters in 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 heart therein has tapped hole, the adjusting bolt the other end is screwed in tapped hole, rotates adjusting bolt and can make the running fix of spool hemisphere.
Novel pressure sealing ball valve, comprise the dust stratification cleaning device, and described dust stratification cleaning device is, at the valve gap upside, air vent connector is housed, air vent connector is connected with high-pressure air source, the other end at air vent connector is equipped with rotating sprinkler, for the pressurized gas of jetting, 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 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 valve is clean to open and close commutation, extends seal ring working life, has reduced production, maintenance and the user cost of product.When having overcome seal clearance and being difficult for levelling, maintenance, dismounting is difficult and cause the defect such as seal ring damage because of reasons such as dust stratifications.

Embodiment
As depicted in figs. 1 and 2, the novel pressure sealing ball valve of the present invention, comprise seal clearance levelling device, spool hemisphere controlling mechanism and dust stratification cleaning device.Seal clearance levelling device is connected to form by valve body 1, seal assembly 9, turnbuckle 13, hold-down bolt 14, O RunddichtringO 10, packing ring 11 and nut 12.Seal assembly 9 is to be formed by connecting by seal 21, O RunddichtringO 22, positioning ring 23 and seal ring 24 use hex head bolts.Valve body 1 is to use Plate Welding, the 4-6 corresponding with seal 21 a M16 screw and 4-6 φ 16 through holes are arranged in the upper-end surface of valve body 1, the in-built hold-down bolt 14 in the M16 hole, seal 21 is lived on the hold-down bolt crown, at the in-built turnbuckle 13 of φ 16, turnbuckle is connected with seal, and seal assembly is lifted in valve body, rotates directly regulating sealing gap of turnbuckle and hold-down bolt.Packing ring 11 and nut 12 all are housed on turnbuckle and hold-down bolt, for lock bolt with prevent Leakage Gas.Axle sleeve 15 is loaded on the left axis hole of valve body 1, rotating shaft 19 1 ends and spool hemisphere splined, and the other end connects pull bar 20.Gland 18 is connected with valve body.Spool hemisphere controlling mechanism is positioning shaft 3, and with fixedly connected, on adjusting bolt 4, spool hemisphere 8 is enclosed within on positioning shaft, and rear adjusting bolt 4 the other ends are screwed in the tapped hole of valve gap 2 with jump ring 5 in succession, and valve gap is contained in the left end hole of valve body.Rotate adjusting bolt, the spool hemisphere rotates mobile position with adjusting bolt, fastening with nut and valve gap behind the location, mobile position.With pull bar 20, control valve opens and closes, seal ring pressurized gas when valve closes, valve closes work.When valve opening, seal ring loses heart, the valve discharging.The dust stratification cleaning device is after the valve discharging completes, and gas joint 6 is connected high-pressure air source, and pressurized gas enter valve body by gas blowout 7, remove valve body inner product ash under the pressurized gas effect.
