Abstract
The invention relates to a wear resistant disc valve, belonging to the technical field of automatic control. The invention is characterized in that an adjustable shaft sleeve is arranged on a valve rod; the valve rod is inserted into the stuffing box of a right valve body; a valve seat is welded on the right valve body; the valve rod is provided with a key, a rocker, an adjusting gasket, and a bearing in sequence; a spring, a top core, and a valve clack are arranged on the rocker; a shaft sleeve is arranged on the left valve body; a sealing gasket, a valve body and the left valve body are arranged on the right valve body, and are fixed by bolts and nuts; a stuffing ring, stuffing, and a stuffing gland bush are arranged on the stuffing box in sequence, and the stuffing is compressed by bolts and nuts. The valve rod is provided with a handle and is fastened by the gasket and bolts. The wear resistant disc valve has simple structure and safe and reliable performance, is convenient for debugging and maintaining the valve when in use, has good sealability, and is capable of ensuring the normal running of the valve under the working condition on a high temperature high pressure pipeline.
Description
Technical field
The present invention relates to a kind of abrasion-proof disk valve, specifically flap partly turns round the type valve, it is industrial extensively to be used in electric power, coking, chemical industry, mine, polysilicon etc., can adopt operation systems such as electronic, pneumatic, intelligent adjusting, belongs to technical field of automatic control.
Background technique
When selecting the more abominable granular material medium of all kinds of General valves circulation working conditions at present for use; because the innate factor of spool and valve pocket; for example: gate valve, stop valve, safety check, butterfly valve, ball valve etc.; there is the circulation dead angle in valve; because valve in use often has hot alternation; the circulation granular material is piled up in the valve dead angle and is hardened, and can cause phenomenons such as valve flowing channel stops up, Sealing can't normally open and close usually, has had a strong impact on the normal use of valve.In order to overcome above difficulty, in prior art, General valve can't meet the demands.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby provide a kind of abrasion-proof disk valve, its sealing configuration is simple, performance is safe and reliable, be convenient to valve debugging and maintenance in use, good seal performance, on the pipeline of high temperature, high pressure, can guarantee the normal operation of valve under working condition.
According to technological scheme provided by the invention, abrasion-proof disk valve comprises valve body, valve rod, valve rod is contained in the valve body, feature is: debug the bearing cover on valve rod, valve rod inserts the right valve barrel stuffing box, be welded with valve seat on the described right valve barrel, on valve rod, comply with key is housed; rocking arm; adjust pad; bearing; spring is housed; plunger tip on rocking arm; flap; the axle sleeve of packing on the left valve barrel; install gasket seal on the right valve barrel; valve body; left valve barrel, adopt double-screw bolt and nut to fix the Packing seat of in stuffing box, packing into according to this; filler; Gland; and compress filler with double-screw bolt and nut.On the described valve rod handle is installed, fastening with packing ring and screw.
But described valve seat and flap sealing surface surfacing or all kinds of alloy materials of built-up welding.Described filler is a flexible graphite packing.
Compared with the prior art the present invention has the following advantages:
1, the operating unit sealing load on the sealing surface of the present invention is synthetic by two-part: the one, and pretightening unit sealing load, the 2nd, the specific pressure that forms by pressure medium.Initial tension of spring and pressure medium always are tending towards flow direction, and it is higher to increase spring pretightening unit sealing load, medium working pressure, and operating unit sealing load is just bigger, and valve seal power is just bigger.Flap overcomes seal pressure under the effect of the pretightening force of spring and medium power, make the valve flap play seal action.
2, be welded with valve seat on the right valve barrel, but valve seat and flap sealing surface surfacing or hardfacing alloy.Sealing is reliable, wear resistance is good.Flexible graphite packing, interchangeability is strong, and when maintenance assembling, mounting or dismounting are convenient, for the quality of valve provides reliable assurance.
3, abrasion-proof disk valve, switch is light, speed is fast, flow resistance is little, be difficult for fouling in valve body, and valve rod drives the flap rotation, and the flap sealing surface can scrape off the dirt that is adsorbed on the sealing surface of seat in rotary course, can effectively improve sealability.
4, abrasion-proof disk valve can also substitute the function of modulating valve, and conversion runner negotiability arbitrarily arrives the function of valve regulated flow.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
