Abstract
The utility model relates to an inner and outer self sealing high pressure steam injection valve, and belongs to a high pressure steam valve. The high pressure steam injection valve used at present has poor sealing performance, short service life and bulky structure, the caliber of the high pressure steam injection valve used at present is greater than the caliber of the DY32 high pressure valve, and the high pressure steam injection valve used at present needs a gear driving device to be operated. The utility model provides a high pressure steam injection valve, comprising a valve body, a bracket, a manual operating mechanism with a thrust bearing and a valve rod which is provide with an inner and outer self sealing mechanism and a valve rod sealing mechanism. The inner and outer self sealing high pressure steam injection valve has the advantages of good sealing property, light weight and convenient operation, and the inner and outer self sealing high pressure steam injection valve can be used for injecting high pressure steam for oil fields.
Description
The utility model belongs to a kind of high pressure steam injection valve.
The present most of import of the high pressure steam injection valve U.S. valve that uses of China oil field uses and just welded extremely because of external leakage occurring in about three months, makes valve lose the possibility of keeping in repair.Domestic valve of the same type is very heavy, generally will be with electronic or hydraulic operation, and current home and abroad bore generally adopts gear drive greater than the high pressure valve of DY32.Oil field general requirements manual control is opening/shutting valve easily.There are shortcomings such as sealing is poor, the life-span is short, operating mechanism is complicated, valve body heaviness in the high pressure steam injection valve that adopts at present.
The purpose of this utility model be to develop a kind of good airproof performance, can manual high pressure steam injection valve.
Technical measures of the present utility model and embodiment are as follows:
Description of drawings:
Fig. 1 is inside and outside self-sealed high pressure steam injection valve structural representation.
Wherein: 1-extendable handle 2-combination nut
3-thrust bearing 4-felt collar
The 5-valve rod 6-feather key that leads
7-gland 8-flap
9-joint ring 10-liner plate
The 12-of 11-filler chamber sealing ring

21-eyelet bolt seat 22-filler
23-asbestos packing 24-filler seat ring
25-support 26-valve body
Inside and outside self-sealed high pressure steam injection valve structure as shown in Figure 1, it is made up of valve body (26), support (25), manual control mechanism and the valve rod mechanism that has a sealing device, it is characterized in that:
A valve body (26) is designed to the Y type, and high pressure vapour import and export passage is the conical molded lines of convergent and flaring, and support (25) places the valve body top, and manual control rotating mechanism, valve rod and sealing device thereof place in support and the valve body,
B manual control mechanism is made up of extendable handle (1), combination nut (2), two thrust bearings (3) and felt collar (4),
C valve rod (5) top connects with combination nut (2) with trapezoidal thread, and there is guiding feather key (6) at the valve rod middle part,
The self-seal device of d valve rod lower end is made up of gland (7), flap (8), joint ring (9) and liner plate (10), and gapped between valve rod and gland, the flap, the valve rod lower surface is sphere,
The outer self-seal device of e valve is by filler chamber (11), sealing ring (12), pressure ring (13), four cyclizations (14), pressing plate (15) and give jack panel (16) and form,
The f valve rod sealing device is made up of filler seat ring (24), asbestos packing (23), filler (22), gland (17), eyelet bolt seat (21), eyelet bolt (18), nut (19), pad (20),
More than each parts promptly constitute inside and outside self-sealed high pressure steam injection valve.
Referring to accompanying drawing and the explanation of above structure, introducing a kind of design pressure that is used for is 18.6MPa(190Kgf/cm
2), temperature is that the high pressure steam injection valve main member parameter of 360 ℃ of medium steams is: this valve shaft is 760mm to length overall, extendable handle (1) length is 300～400mm, external diameter φ 38mm, valve rod (5) diameter phi 36mm, stem lower portion and gland (7) and flap (8) fit diameter are respectively 38mm and 52mm.Joint ring (9) is made of stellite, and sealing ring (12) is with suppressing flexible graphite material, and thrust bearing (3) is selected GB301-64 specification 8116 for use, and the equipped screw thread of valve rod and combination nut is Tr36 * 6LH-7H/Te.
The operating principle of inside and outside self-sealed high pressure steam injection valve is: when the manipulation extendable handle was driven valve, valve rod rose and drives the self-seal device rising, and high pressure vapour enters outlet injection oil field from inlet.When valve-off, handle extendable handle and make valve rod downward, compress up to flap (8) and joint ring (9), this moment, steam pressure compressed flap automatically, reached interior self sealss; Steam pressure acts on the filler chamber bottom surface and compresses seal, reaches outer self-packing purpose.
The utility model has the advantages that: (1) designs reasonable idea, structure is light and handy, and such as the heavy 72Kg of the high pressure valve of DY80, and other similar valves heavily are 220～380Kg; (2) this valve hand steerable opens and closes, and can save complicated transmission mechanism, makes things convenient for oil field operation; (3) this valve seal property is good, the life-span is long, cost is low. Inside and outside self closing high pressure steam injection valve is desirable high pressure steam injection valve.
