Abstract
The utility model provides a pneumatic lifting-revolving cock valve with the functions of high temperature, high pressure and abrasion resistance. A valve body and a valve cover form a valve main body, a valve seat arranged in a valve cavity is matched with a cock body to realize on/off of the valve, a handle is arranged on a valve rod connected with the cock body, and a pneumatic device is mounted on a bracket at the upper end part of the valve rod; and the materials of the valve body and the valve cover adopt PI or ASTM A217 WC6 or WC9. The cock body can realize on/off under zero friction due to the lifting-revolving structure, and solve the problem of a sealing surface abraded by solid particle media; the material of the valve main body has the advantages of high temperature resistance and corrosion resistance against hydrogen sulfide; hard cobalt-base alloys bead welded on the sealing surface of the valve seat and the cock body achieves higher abrasion resistance of the valve; sweeping components are arranged on the neck parts of the valve body and the valve cover, high temperature steam enters a valve cavity to heat the media through the sweeping components, so as to prevent the media from cocking; and the valve can meet the requirements of special working conditions of ethylene devices and delayed coking devices for petroleum refineries.
Description
Technical field the utility model belongs to the machinery valve technical field, relates in particular to a kind of pneumatic high-temperature and high-pressure wearable lifting-rotary stopcock that is applied to ethylene unit and oil refinery delayed coking unit.
The general stopcock of background technique is a kind ofly to do the keying that 90 ° of rotations realize valve by cock body in valve body, is divided into soft seal type and hard sealed type by its seal form.Though soft seal type stopcock sealability is good, be subjected to the restriction of its sealing material can not be used for worst hot case; Though hard sealed type stopcock is applicable to worst hot case, its sealing surface easily is worn in the medium of solid particle is arranged and influences the sealability of valve.The pipeline medium of ethylene unit and oil refinery delayed coking unit contains tar gas, temperature height (about 500 ℃), is attended by H
2S and coke breeze solid particles, and easily coking.This medium requires valve except that having excellent sealing performance, and high temperature resistant, anti-H also should be arranged
2The S burn into prevents functions such as coking, and existing general stopcock is difficult to satisfy the requirement of above-mentioned working condition.
The summary of the invention the purpose of this utility model is to provide a kind of high temperature resistant, high pressure resistant, wear-resistant, corrosion resistant pneumatic high-temperature and high-pressure wearable lifting-rotary stopcock that can satisfy ethylene unit and the requirement of oil refinery delayed coking unit.
For achieving the above object, the technological scheme taked of the utility model is:
A kind of pneumatic high-temperature and high-pressure wearable lifting-rotary stopcock, valve body and valve gap are formed valve body, the valve seat that is provided with in the valve pocket cooperates the keying that realizes valve with cock body, and handle is set, the support place installation Pneumatic actuator of valve rod upper end portion on the valve rod that cock body links to each other; Valve body, valve gap material adopt P
IOr ASTM A217 WC6 or WC9.
Sealing surface weld deposit cobalt base hard alloy between described valve seat and the cock body.
Be provided with the purging stop valve on described valve body and the valve gap neck, purge stop valve and be communicated with valve pocket by purging to take over.
Above-mentioned pneumatic high-temperature and high-pressure wearable lifting-rotary stopcock that the utility model provides because cock body is designed to lifting-rotary structure, makes cock body realize opening and closing under no Frotteurism, has solved the problem of solid particle medium to sealing surface wear.Because the valve body material adopts P
IOr ASTM A217 WC6 or WC9, make valve have the high temperature of bearing (about 500 ℃), high pressure resistant (600lb/PN100), anti-H
2The performance of S corrosion.In addition, because the sealing surface weld deposit cobalt base hard alloy between valve seat and cock body makes valve have higher wear-resisting property.Owing to be provided with purging component, outside high-temperature steam enters in the valve by purging component medium is heated, in case the medium coking.Therefore, this valve has high temperature resistant, high pressure resistant, anti-H
2The S burn into prevents functions such as medium coking, can satisfy the requirement of ethylene unit and oil refinery delayed coking unit special operation condition condition, to realize homemade import substitution.
Description of drawings Fig. 1 is the structural representation of pneumatic high-temperature and high-pressure wearable lifting-rotary stopcock;
Fig. 2 is the left TV structure schematic representation of Fig. 1.
Among the figure: the 1-valve body; The 2-cock body; The 3-valve seat; The 4-valve rod; The 5-valve gap; The 6-Pneumatic actuator; The 7-support; The 8-handle; 9-purges stop valve; 10-purges adapter.
Embodiment as shown in Figure 1, among the pneumatic high-temperature and high-pressure wearable lifting that the utility model provides-rotary stopcock embodiment, valve body 1 and valve gap 5 are formed the main body of valves, valve seat 3 and the cock body 2 that is provided with in the valve pocket cooperatively interacts and realizes the keying of valve, with on the valve rod 4 that cock body 2 links to each other handle 8 is set, Pneumatic actuator 6 is installed on the support 7 of valve rod 4 upper end portions.Valve body spare valve body 1, valve gap 5 materials adopt P
I(ZG1Cr18Ni9Ti) or ASTM A217 WC6 or WC9, P
I(ZG1Cr18Ni9Ti) at 570 ℃, these materials also have anti-H to maximum operation (service) temperature in 650 ℃, ASTM A217 WC6 or the highest use temperature of WC9
2The performance of S corrosion.Sealing surface weld deposit cobalt base hard alloy between valve seat 3 and the cock body 2, HRC 〉=35, the hardness height guarantees that valve sealing surface in switching process has good wear resistance.Be provided with on the neck of valve body 1 and valve gap 5 and purge stop valve 9, purge stop valve 9 and take over 10 and be communicated with valve pocket by purging.Outside high-temperature steam enters in the valve pocket medium is heated by purging stop valve 9, purging adapter 10, in case the medium coking.
During Open valve, at first start Pneumatic actuator 6, Pneumatic actuator 6 actuate valve stem 4 drive that cock bodys 2 are done lifter motion, the sealing surface of lifting off a seat, and use handle 8 rotation valve rods 4 then and then drive cock body 2 and do 90 ° of rotations, the passage of the passage of cock body and valve body is communicated realize opening; During throttle down, use handle 8 rotation valve rods 4 earlier and then drive cock body 2 and do 90 ° of rotations, drive cock body 2 by Pneumatic actuator 6 actuate valve stem 4 again and do descending motion, make the passage of cock body and the channel vertical of valve body realize closed.This structure makes valve realize opening or closing under no Frotteurism, has reduced the switching torque of valve, and valve is is under high pressure easily opened and closed, and also protects the sealing surface of valve not to be scratched simultaneously, has solved the problem of solid particle medium to sealing surface wear.In addition, when valve need purge, open purging stop valve 9, outside high-temperature steam is taken over 10 by purging stop valve 9 and purging and is entered enforcement purging in the valve, medium is heated, in case the medium coking.In the time of need not purging, shut-down purge stop valve 9 gets final product.
Above-described only is preferred embodiment of the present utility model.Should be understood that those of ordinary skill, under technology enlightenment provided by the utility model, can also make other equivalent modifications and improvement, also should be considered as protection domain of the present utility model for valve technology field.
