Description
One, technical field:
The utility model relates to a kind of valve, especially to the special valve that high temperature and high pressure steam controls, is applicable to the engineering such as electric heating and oil field gas injection exploitation.
Two, background technique:
Along with the high speed development of the national economy of China.The electric power needed and crude oil growth at double, China's heavy oil asphalt resource distribution is extensive, has found more than 70 heavy oil field in 12 basins, has estimated that Chinese heavy petroleum asphalt stock number can reach 300 × more than 108t.At present, China has verified and has reached 16 × 108t with control reserve, the fourth-largest viscous crude producing country of the world after the Shi Ji U.S., Canada and Venezuela, most of heavy crude reservoir of China is all little fault block heavy crude reservoir substantially, this kind of oil reservoir belongs to low-grade petroleum resources, crude oil property is poor, and exploitation, oil recovery, surface collection transport with intractability large.Viscous crude field exploitation in Productivity Construction, note adopt unification process engineering for the exploitation of little fault block viscous crude field have investment and operating cost minimum, the advantage of good economy performance.Valve for controlling steam pipework gets more and more, and simultaneously more and more more viscous crude fields are developed construction, and because viscous crude density is large and harden, need inject the steam of High Temperature High Pressure to dissolve viscous crude, the corrosive material content such as the sulphide simultaneously in crude oil are high.Just key effect is played at the valve of well head.First dissolve viscous crude by the steam of valve injection High Temperature High Pressure.
The steam pipework of tradition viscous crude adopts stop valve, and flow resistance is large, and steering force distance is large, inconvenient operation, inefficiency.Whole pipeline is very long, extremely inconvenient, and equipment cost becomes large simultaneously.Flap is due to the compensation after not can solve the resistance to height of seal ring and Long-Time Service and wearing and tearing.Working life is extremely short, less than the valve just needing for 10 months more to renew, causes great waste, and stops work when changing on the impact of producing and need a large amount of manpowers.
Three, model utility content:
The utility model object is, solve the flap sealing shortcoming of existing stop valve, and flow resistance is large, steering force is apart from large, and the deficiency of inconvenient operation, proposes a kind of high temperature and high pressure steam special valve, can better be used for High Temperature High Pressure defeated vapour oil recovery pipeline.
The technical solution of the utility model is, high temperature and high pressure steam special valve, it is characterized in that comprising valve body 14, handwheel 2, Stem Mut 5, bearing 6, Gland 7, support 8, combined packing 9, Packing seat 10, Stuffing box 11, valve rod 12, flap 13, import and outlet flow, inlet channel and valve rod are 40-55 degree angle, valve body lower inner passage arranges flap seat, the longitudinal section of flap is dry font, valve rod 12 blocks import and outlet flow when driving flap 13 to be sitting in flap seat, the groove connection inlet channel of font is done in the longitudinal section of flap this moment, Gland 7 is provided with successively from top to bottom between flap and valve rod, combined packing 9, Packing seat 10, Stuffing box 11, the top of valve body is provided with support along the length direction of valve rod, and support is provided with the bearing waling Stem Mut, and valve rod rotates up and down in Stem Mut, and handwheel is installed by keyway in the top of valve rod, valve body lower inner passage imports and exports the long-pending 1.5-2 of cross section of fluid channel doubly.
The utility model is a kind of stop valve, the bump that flap does font is conducive to location, valve seat also has corresponding slotted eye, blocks import and outlet flow, this moment the longitudinal section of flap do font groove be communicated with inlet channel have high pressure steam engine produce from compress strength valve is not leaked.The keying of valve is driven by handwheel 2.
Utility model works process is as follows: when valve rod moves upward, and valve rod drives flap upwards to promote, and opens whole passage, injects the steam of High Temperature High Pressure.When valve rod moves downward, when arriving rest position, close whole passage, terminate the steam injection of High Temperature High Pressure.
The beneficial effects of the utility model, propose a kind of high temperature and high pressure steam special valve, and solve the flap sealing shortcoming of existing stop valve, and flow resistance is large, steering force is apart from large, and the deficiency of inconvenient operation, can better be used for High Temperature High Pressure defeated vapour oil recovery pipeline.Valve adopts self-tightening sealing structure, and be combined packing 9 and Stuffing box 11 double seal to the sealing in the middle part of valve rod, pressure more high sealing effect is better.Valve body lower inner passage is the sectional area runner importing and exporting runner twice, and turnover runner and valve rod are y-type structure, reduces resistance to the impact of recovering the oil.Bearing means is adopted to facilitate actuating valve gate switch and laborsaving.Flap adopts and falls resistance structure, minimizing fluid to the destruction of flap, greatly strengthens the working life of valve.Filler adopts composite structure, ensures the reliability of sealing.Adopt different types of carbide reactor welding technology to make the sealing surface of flap and flap seat corrosion-resistant, shock-resistant, ensure the quality index of valve.
Four, accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
Five, embodiment:
As shown in the figure, dust cover 1, handwheel 2, impact block 3, bearing gland 4, Stem Mut 5, bearing 6, Gland 7, support 8, combined packing 9, Packing seat 10, Stuffing box 11, valve rod 12, flap 13, flap seat 13-1, valve body 14, inlet channel 15 and outlet flow 16.
Comprise valve body 14 (valve body adopts Integral die-forged structure), handwheel 2 and the impact block 3 (for stopping handwheel position) coordinated, bearing gland 4, Stem Mut 5, bearing 6, Gland 7, support 8, filler adopts double combinations structure namely to comprise combined packing 9, Stuffing box 11, Packing seat 10, valve rod 12, flap 13, inlet channel 15 and outlet flow 16, inlet channel and valve rod are 40-55 degree angle, valve body lower inner passage arranges flap seat, flap adopts and falls resistance structure, namely the longitudinal section of flap is dry font, valve rod 12 blocks import and outlet flow when driving flap 13 to be sitting in flap seat 13-1, this is the steam self-tightening sealing structure of high temperature high voltage resistant.Flap 13 and flap seat adopt carbide reactor welding technology and fine finishing, and the groove connection inlet channel of font is done in the longitudinal section of flap this moment, is provided with Gland 7, combined packing 9, Packing seat 10, Stuffing box 11 from top to bottom successively between flap and valve rod; The length direction along valve rod of valve body 14 is provided with support 8, and support 8 is provided with the bearing 6 of valve rod waled Stem Mut 5 and rotate in Stem Mut, and handwheel 2 is installed by keyway in the top of valve rod.Adopt bearing to make the open-close convenient of valve flexible, the life-span of the whole valve of protection is also beneficial to.Bearing 6 is provided with bearing gland 4.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
