Description
Technical field
The utility model belongs to field of oil drilling, and in particular, the utility model relates to a kind of drilling pump fluid end assembly.
Background technique
In traditional drilling pump fluid end, clack box is generally designed to " I " shape, suction valve and expulsion valve are installed in clack box inside, and suction valve is positioned at immediately below expulsion valve, its structural representation is shown in Fig. 1, because the pressure difference at the upper and lower two ends of suction valve in drilling pump fluid end is comparatively large, therefore suction valve assembly relatively easily damages.When the suction valve assembly as easily damaged parts damages and needs to change, could take out with special tool after the parts such as the cylinder cap of the expulsion valve above suction valve, valve gap and clack box side all must being taken down and suck valve seat, thus change the suction valve damaged, such operation more complicated, be inconvenient to keep in repair, and all mud that can lose in high pressure exhaust manifold, because mud cost compare is high, this can increase the cost of drilling process greatly.
Model utility content
The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, provides a kind of easy to maintenance, drilling pump fluid end assembly that can be cost-saving.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of drilling pump fluid end assembly, it comprises suction valve assembly, expulsion valve assembly, clack box, cylinder sleeve, high pressure exhaust manifold, described clack box comprises suction fluid cylinder, discharges fluid cylinder, described discharge fluid cylinder side is connected with cylinder sleeve by bolt, opposite side is connected with suction fluid cylinder by bolt, and is provided with seal ring between suction fluid cylinder and discharge fluid cylinder; Pipeline in described discharge fluid cylinder is connected with the pipeline in cylinder sleeve, the pipeline sucked in fluid cylinder respectively; Described suction valve assembly is positioned at and sucks fluid cylinder, and suction valve assembly is provided with the suction valve gland matched with it, and suction valve gland is provided with the suction valve gap matched with suction valve gland; Described expulsion valve assembly is positioned at discharges fluid cylinder, and expulsion valve assembly is provided with the expulsion valve gland matched with it, and expulsion valve gland is provided with the discharge valve gap matched with expulsion valve gland;
As preferably, described seal ring is elastic seal ring;
As preferably, between described discharge fluid cylinder and cylinder sleeve, be provided with elastic seal ring;
As preferably, the pipeline in described discharge fluid cylinder, the pipeline in cylinder sleeve, the internal diameter of the pipeline sucked in fluid cylinder are identical;
As preferably, the pipeline in described discharge fluid cylinder and the pipeline in cylinder sleeve orthogonal;
As preferably, the pipeline in described discharge fluid cylinder is orthogonal with the pipeline sucked in fluid cylinder;
As preferably, between described suction valve gland and suction valve gap, be provided with seal washer;
As preferably, between described expulsion valve gland and discharge valve gap, be provided with seal washer.
Clack box is divided into and sucks fluid cylinder and discharge fluid cylinder by the utility model product, and clack box becomes " L " shape structure from " I " shape structure, by suction valve and expulsion valve independent, be placed in respectively and suck fluid cylinder and discharge in fluid cylinder; Compared with traditional drilling pump fluid end, the size of the utility model product and frame connecting bolt, number, mounting point are all constant, this ensure that the interchangeability of the utility model fluid end and conventional fluid torque end.
Suck fluid cylinder in the utility model product and adopt 8 high strength exploitation with discharge fluid cylinder, ensure that the stability sucking fluid cylinder and be connected with discharge fluid cylinder; What the sealing sucked between fluid cylinder and discharge fluid cylinder adopted is the elastic seal ring that the specific rubber that can bear High Temperature High Pressure is made, and this elastic seal ring can play good sealing effect, also can play good effectiveness in vibration suppression, avoids the wearing and tearing sucking fluid cylinder; The utility model product arranges suction valve gland between suction valve assembly and suction valve gap, between expulsion valve assembly and discharge valve gap, expulsion valve gland is set, and seal washer is set between suction valve gland and suction valve gap, between expulsion valve gland and discharge valve gap, make the sealing effect of product better.
When needing to change when suction valve assembly damage in the utility model product, only the valve gap on suction fluid cylinder top, valve gland need be pulled down, namely available professional tool takes out suction valve assembly, thus the suction valve that replacing or maintenance damage; In the process, expulsion valve assembly is in closed condition, and the mud above expulsion valve assembly and in high pressure exhaust manifold all can not flow backward to suction fluid cylinder, and therefore this part mud also can not lose, and avoids cost of idleness.
Compared with prior art, the beneficial effects of the utility model are:
The utility model product is convenient and swift and mud loss is few when changing suction valve assembly as easily damaged parts, not only easy to maintenance, and cost-saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional drilling pump fluid end assembly;
Fig. 2 is the structural representation of the utility model product;
Wherein, the title corresponding to reference character is respectively:
1-discharges valve gap, 2-expulsion valve gland, 3-high pressure exhaust manifold, 4-expulsion valve assembly, and 5-discharges fluid cylinder, and 6-sucks valve gap, 7-suction valve gland, 8-suction valve assembly, and 9-sucks fluid cylinder, 10-cylinder sleeve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
Embodiment
As shown in Figure 2, a kind of drilling pump fluid end assembly, it comprises suction valve assembly 8, expulsion valve assembly 4, clack box, cylinder sleeve 10, high pressure exhaust manifold 3, and clack box comprises suction fluid cylinder 9, discharges fluid cylinder 5; Discharge fluid cylinder 5 side to be connected with cylinder sleeve 10 by bolt, opposite side is connected with suction fluid cylinder 9 by bolt, and is provided with elastic seal ring between suction fluid cylinder 9 and discharge fluid cylinder 5, discharges between fluid cylinder 5 and cylinder sleeve 10 and is provided with elastic seal ring; The pipeline of discharging in fluid cylinder 5 is connected with the pipeline in cylinder sleeve 10, the pipeline sucked in fluid cylinder 9 respectively, discharge pipeline in fluid cylinder 5 and the pipeline in cylinder sleeve 10 is orthogonal and internal diameter of the pipeline is identical, discharge pipeline in fluid cylinder 5 and the pipeline in suction fluid cylinder 9 is orthogonal and internal diameter of the pipeline is identical; Suction valve assembly 8 is positioned at and sucks fluid cylinder 9, and suction valve assembly 8 is provided with the suction valve gland 7 matched with it, and suction valve gland 7 is provided with the suction valve gap 6 matched with suction valve gland 7, is provided with seal washer between suction valve gland 7 and suction valve gap 6; Expulsion valve assembly 4 is positioned at discharges fluid cylinder 5, and expulsion valve assembly 4 is provided with the expulsion valve gland 2 matched with it, and expulsion valve gland 2 is provided with the discharge valve gap 1 matched with expulsion valve gland 2, is provided with seal washer between expulsion valve gland 2 and discharge valve gap 1.
