Abstract
The utility model discloses an adjustable fixing throttle valve including a valve body (1), an oil nozzle assembly (2), a union (3) and a sealing head (6), the valve body (1) is provided with a T-shaped three way channel which includes a vertical channel and two concentric horizontal channel, wherein, the vertical channel is a medium input channel, one of the horizontal channels is a medium output channel, which is provided with the oil nozzle assembly (2) via footsteps, the end mouth of the other horizontal channel is rotationally and compactedly equipped with the sealing head (6) via the union (3); the oil nozzle assembly (2) consists of an oil nozzle body (9), a throttling oil nozzle (10) and a clip spring (11), the oil nozzle body (9) is restrictedly provided with the throttling oil nozzle (10) via the clip spring (11). According to the requirement of the crude oil output at the output well head, the adjustable fixing throttle valve provides a plurality of specified throttling oil nozzles on one valve and changes the flow of the channels by adjusting the appropriate diameter of the throttling oil nozzles.
Description
Technical field
The utility model relates to the main accessory of well head production tree equipment, is specifically related to the adjustable type fixed restrictive valve that defeated well head control well head crude output is adopted in a kind of extensive use.
Background technology
At present, the fixed restrictive valve that use in known oil field is to come throttling with positive choke, and is unadjustable on pipeline discharge value size, and high pressure resistant poor, and the antiscour rate is low, and application life is short, influences programming.
Summary of the invention
The purpose of this utility model is: a kind of adjustable type fixed restrictive valve is provided, thereby the size of chewing by more changing oil changes the flow that the orifice size of liquid is controlled fluid, the assembling simplified structure, install and remove easy to connect, maintaining is simple, and is high pressure resistant, antiscour, application cost reduces, the long service life of valve.
Technical solution of the present utility model is: this choke valve comprises that valve body, oil chews assembly, union and seal head, establish "T"-shaped three way type passage in the valve body, be a vertical channel and two concentric horizontal channels, vertical channel is the medium input channel, one of them horizontal channel is the medium output channel, by step oil is installed in the medium output channel and is chewed assembly, the port of another horizontal channel rotatably compresses the installation seal head by union; Described oil chew assembly by oil chew body, throttling oil is chewed with jump ring and is formed, in oil is chewed body, chew by jump ring limit mounting throttling oil.
Wherein, back-up ring is installed and prevents that union is loosening on seal head.
Wherein, establish interface on the seal head, plug, stop valve or pressure meter are installed on the interface.
Wherein, seal head is installed in the passage of valve body by at least one sealing ring.
During assembling, provide the throttling oil of 20 specifications to chew, select the throttling oil of suitable diameter to chew, open seal head, chew the taking-up special tool, from valve channel throttling oil is chewed to change and put in place by oil according to output.
Major advantage of the present invention:
1, can be according to the requirement of adopting defeated well head crude output, on a deck valve door, provide several specification throttling oil to chew selection, change suitable throttling oil and chew the flow that diameter changes passage, be suitable for various working, especially the operating mode of demand condition harshness is used, and the popularizing value prospect is arranged.
2, the 1/2NPT interface is arranged on the seal head, can be used to install plug or connect stop valve, pressure meter.
3, seal head adopts oil to link to each other the ninth of the ten Heavenly Stems with valve body, and by the sealing of twice " O " type circle double insurance, the dismounting transposing is convenient, designs simplification, flexibly and fast.
4, selection is reasonable, uses different materials at different positions, has improved decay resistance and antiscour rate, improves application life greatly.

Wherein, back-up ring 7 is installed and prevents that union 3 is loosening on seal head 6.
Wherein, establish interface on the seal head 6, plug 8, stop valve or pressure meter are installed on the interface.
Wherein, seal head 6 sealing rings 4,5 are installed in the passage of valve body 1.
During assembling, provide the throttling oil of 20 specifications to chew, select the throttling oil of suitable diameter to chew 10, open seal head 6, chew taking-up special tool oil by oil and chew spanner 12, from valve body 1 passage throttling oil is chewed 10 replacings and put in place according to output.
Claims (3)
