Abstract
The utility model discloses a high-pressure fixed throttle valve, comprising valve body and throttling element thereof. The medium channel of the valve body is T-shaped tee joint structure with a vertical channel and two concentric horizontal channel, the vertical channel is input channel of medium and one of the horizontal channel is output channel of medium with throttling element arranged in the channel, the other horizontal channel is closed by plugs, the plugs include plugging head, plug screw and alloy blocks. The sealing port surface of the valve body shapes internal conical, the front-end of the plugging head shapes external conical and matches with the internal conical of the valve body sealing port surface, and the external conical has counterbore with alloy blocks inlayed, the external middle-back end of the plugging head has a thread and plug screw fastening on the thread. the utility model employs metal to metal seal, so as to improve sealing property and anti-scour property, prolong service life and can be widely used, especially application in working condition of harsh demand conditions with fine expand use-value.
Description
Technical field:
The utility model relates to the throttling arrangement of adopting defeated or test manifold on the oil gas well site, specifically is a kind of high pressure fixed restrictive valve.
Technical background:
When adopting defeated, test jobs in the oil gas well site, must use the throttle valve that has the positive choke throttling, throttle valve need have anti-ly wash away, high pressure resistant, anticorrosive, characteristics that the life-span is long, and in the past, heavy wall tubing screw thread 2 7/8 is often used in the end cock of up-to-date fixed restrictive valve " UP TBG; this fixed restrictive valve high pressure resistant poor, the antiscour rate is low, working life is short, influences project progress.
Summary of the invention:
The utility model purpose provides the high pressure fixed restrictive valve of a kind of high pressure resistant, antiscour rate height, long service life.
The technical solution of the utility model is:
A kind of high pressure fixed restrictive valve, comprise valve body and throttle element wherein, the medium channel of described valve body is "T"-shaped three-port structure, have a vertical passage and two concentric horizontal channels, wherein vertical passage is the medium input channel, a horizontal channel is the medium output channel, throttle element is arranged in this passage, another horizontal channel is sealed by blocking piece, the blocking piece of described another horizontal channel comprises plug, plug screw and alloy block, the sealed mouth surface of described valve body is inner conical, and described plug front end is an external conical shape, and is suitable with valve seal oral thermometer face inner conical, this external conical shape has deep gouge, alloy block is embedded in this groove, and the rear end has screw thread in the outside of plug, and plug screw is fastened on this screw thread.
The sealed mouth surface root of described valve body has screw thread.
The outer-rear end of described plug has circlip groove, and the card key is arranged in the circlip groove
The outer surface of described plug has two road sealing grooves, and seal ring is installed in the groove.
The beneficial effects of the utility model are: adopted metal to metal seal, improved sealability and antiscour rate, prolonged working life, widely applicable, especially the operating mode of demand condition harshness is used, and popularizing value is good.
Description of drawings:
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment:
Referring to Fig. 1: the utility model comprises valve body 1 and throttle element wherein, the medium channel of valve body 1 is "T"-shaped three-port structure, have a vertical passage and two concentric horizontal channels, vertical passage is the medium input channel, one of them horizontal channel is the medium output channel, throttle element is arranged in this passage, another horizontal channel is sealed by blocking piece, this blocking piece comprises plug 2, plug screw 3 and alloy block 5, the sealed mouth surface of valve body 1 is inner conical, and surperficial root has screw thread, and plug 2 front ends are external conical shape, suitable with valve body 1 sealed mouth surface inner conical, this external conical shape has counterbore, and alloy block 5 is embedded in this groove, and the rear end has screw thread and/or circlip groove in the outside of plug 2, plug screw 3 is fastened on this screw thread, card key 4 is close to plug screw 3 and is arranged in the circlip groove, with plug screw 3 lockings, prevents that plug screw 3 is loosening or comes off, also two road sealing grooves can be set at the outer surface of plug 2, seal ring is installed in the groove.
The utility model has adopted metal to metal seal, has improved sealability and antiscour rate, has prolonged working life, can be suitable for various working, and especially the operating mode of demand condition harshness is used, and popularizing value is good.
