Description
Technical field
The utility model relates to a kind of production tree equipment, is specifically related to a kind of fixation type throttle valve of production wellhead.
Background technique
Throttle valve is by changing throttling cross section or chock length to control the valve of fluid flow.In oil recovery, in the work production process of gas production, owing to there is a large amount of impurity in flowing medium, as the grains of sand etc., these impurity produce very strong souring to runner hole, that particularly washes away in the ingress of adjust flux is more severe, therefore, adopt the common oil nozzle life-span manufactured by steel very short, need to change oil nozzle assembly parts frequently, therefore consider that oil nozzle material adopts cemented carbide, its resistance to flexure is 1500MPa, hardness is HRA89, ratio common material is through the more resistance to erosion of the oil nozzle manufactured by heat treatment, wear-resistant and corrosion-resistant, but Hardmetal materials density is very large, reach 15g every cubic centimetre, price is high, add manufacture cost greatly.In addition, because original oil nozzle assembly parts is fixedly connected with throttle valve, whole throttle valve is caused normally to use like this, need to change throttle valve, delay the normal acquisition of fluid, affect picking rate, simultaneously because oil nozzle assembly parts and throttle valve are fixedly connected with, the throttle valve maintenance changed also extremely bothers, and maintenance cost is higher.
Summary of the invention
For solving the problem, the utility model discloses a kind of fixation type throttle valve, assembly structure be simple, resistance to erosion, anticorrosive, oil nozzle is changed convenient and swift, can by realizing the control of flow with the oil nozzle changing different pore size.
A kind of fixation type throttle valve, comprise valve body and valve gap, valve pocket is provided with in described valve body, described valve pocket is T-shape three circulation passage, be a horizontal channel and upper and lower two concentric vertical passages, in described lower vertical passage, oil nozzle assembly is installed, the top of described upper vertical passage is provided with valve gap, described valve gap is connected with valve body by union, " O " RunddichtringO is provided with the inside contact surface of upper vertical passage outside described valve gap, described oil nozzle assembly comprises body and oil nozzle, gas channel is provided with in described body, in the middle part of described body, outside is provided with outside thread, described body is connected with the screw-internal thread fit on vertical passage inwall under valve pocket by outside thread, described oil nozzle is fixedly mounted on inside bodies top by Spielpassung.
As further improvement of the utility model, described bodies top is also provided with circlip, and described circlip is positioned at the top of oil nozzle.
As further improvement of the utility model, the surface of contact of described oil nozzle and body is provided with " O " RunddichtringO.
As further improvement of the utility model, described body bottom portion and lower valve chamber contact internal walls face are also provided with twice " O " RunddichtringO.
As further improvement of the utility model, the bulk material in described oil nozzle assembly is cemented carbide.
As further improvement of the utility model, the material of described oil nozzle is pottery.
Compared with prior art, the utility model tool has the following advantages and beneficial effect: valve gap adopts union to be connected, and oil nozzle is changed more convenient; The separately design of oil nozzle and body, both reduced equipment cost, again reduced the expense of repair and replacement, and oil nozzle adopts pottery to make, and has resistance to erosion, erosion-resisting performance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is oil nozzle assembly structure schematic diagram in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometrical center respectively.
As shown in Figure 1-2, a kind of fixation type throttle valve, comprises valve body 1 and valve gap 2, is provided with valve pocket 3 in valve body 1, and valve pocket 3 is T-shape three circulation passage, is a horizontal channel 31 and upper and lower two concentric vertical passages.Wherein, in lower vertical passage 32, oil nozzle assembly 4 is installed, the top of upper vertical passage 33 is provided with valve gap 2, valve gap 2 is connected with valve body 1 by union 5, be provided with " O " RunddichtringO 6 outside valve gap 2 to be formed seal with the inside contact surface of upper vertical passage, oil nozzle assembly 4 comprises body 41 and oil nozzle 42, gas channel is provided with in body, body 41 material in the present embodiment in oil nozzle assembly is cemented carbide, the material preferably ceramic pottery of oil nozzle 42, there is resistance to erosion, erosion-resisting performance, body 41 and oil nozzle 42 adopt separate design, adopt two kinds of materials, both the integral production cost of throttle valve had been reduced, again reduce maintenance cost, the parts (oil nozzle or body) of damage only need be changed during replacing, change traditional phenomenon needing simultaneously to change body and oil nozzle.
In the middle part of body 41, outside is provided with outside thread (as shown in Figure 2), body 41 is connected with the screw-internal thread fit on vertical passage under valve pocket 32 inwall by outside thread, in order to seal better, prevent dielectric leakage, be also provided with twice " O " RunddichtringO 6 and form ring packing bottom body 41 with on vertical passage under valve pocket 32 contact internal walls face.Oil nozzle 42 is fixedly mounted on body 41 inside top by Spielpassung, and in order to prevent oil nozzle to scurry out under the effect of reaction force body, be also provided with circlip 7 at the top of body 41, circlip 7 is positioned at the top of oil nozzle 42 for stopping oil nozzle.
Contact with the sealing of body to realize oil nozzle, " O " RunddichtringO 6 together with the surface of contact of oil nozzle with body is provided with.Circlip 7 by realizing the control of flow with the oil nozzle changing different pore size, first can take out during replacing by the utility model, then changes oil nozzle, simple and fast.
