Description
Technical field
The utility model relates to field fracturing equipment, particularly relates to a kind of overhead-valve mechanism of high-pressure plunger pump suction manifold.
Background technique
Current hydraulic fracturing technology is widely used in oilfield exploitation, and high-pressure plunger pump is fracturing supercharging equipment.Need to rinse high-pressure plunger pump with clear water at the end of pressing crack construction, clear water is easily attached on the valve rubber of fluid end valve body, under winter low temperature working environment, clear water freezes and causes valve body and valve seat to be bonded together, not easily push up when equipment reuses and open valve body, cause high-pressure plunger pump to suck liquid.
The patent No. is that the patent document of CN201420115819 discloses " a kind of fracturing pump low pressure suction manifold, fracturing unit truck and fracturing unit group ", comprise the arm that house steward is connected with house steward, house steward is provided with unthreaded hole, be arranged with the push rod that can move axially in unthreaded hole, the push rod in this structure can play the effect that valve body is opened on top.Known from CN201420115819 patent document, the push rod Manual-pushing in " a kind of fracturing pump low pressure suction manifold, fracturing unit truck and fracturing unit group ".But in the production work of reality, the suction pressure that fluid end valve body normally works is 0.7 MPa, the valve body breakdown that this pressure all cannot will freeze, therefore depends merely on manual promotion of manpower and valve body top cannot be realized to open.If open valve body by top, impact push rod end, one is that operation is original, lost labor; Two is that strong vibration can injury device and seal arrangement.As can be seen here, the patent No. is that the patent document disclosed " a kind of fracturing pump low pressure suction manifold, fracturing unit truck and fracturing unit group " of CN201420115819 exists certain drawback.
Summary of the invention
The purpose of this utility model is to provide a kind of overhead-valve mechanism of high-pressure plunger pump suction manifold, and structure is simple, easy to operate, can be opened on the valve body top of freezing to be connected safe and efficiently, ensures the work that high-pressure plunger pump also can be normally orderly under low-temperature condition.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of overhead-valve mechanism of high-pressure plunger pump suction manifold, comprise push rod, suction manifold arm, suction manifold house steward, described suction manifold house steward is arranged on the bottom of suction manifold arm, push rod is arranged on the inside of suction manifold arm and suction manifold house steward, steel pipe is fixed with in the bottom of suction manifold house steward, one end of described push rod is as the force side for jack-up fluid end valve body, the other end of push rod is screwed onto the inside of steel pipe, between push rod and steel pipe, seal ring is installed, the screw thread stretching out lengths of steel pipes at push rod is bolted with nut.
Described push rod comprises A shaft part, B shaft part, C shaft part, and the diameter of described A shaft part is greater than the diameter of B shaft part, and the diameter of described B shaft part is greater than the diameter of C shaft part, and the side near A shaft part on B shaft part is provided with screw thread.
The inside of described steel pipe is disposed with screw thread, seal groove inwards from port.
Compared with prior art, the beneficial effects of the utility model are:
A kind of overhead-valve mechanism of high-pressure plunger pump suction manifold, structure is simple, easy to operate, push rod is connected with steel pipe sealing rear thread, easily, fast, safely the valve body top of freezing to be connected can be opened by screwing push rod, ensure the work that high-pressure plunger pump also can be normally orderly under low-temperature condition, thus improve the usability of high-pressure plunger pump low-temperature working environment.

Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following mode of execution.
As Figure 1-Figure 2, a kind of overhead-valve mechanism of high-pressure plunger pump suction manifold, comprise push rod 2, suction manifold arm 4, suction manifold house steward 6, described suction manifold house steward 6 is arranged on the bottom of suction manifold arm 4, push rod 2 is arranged on the inside of suction manifold arm 4 and suction manifold house steward 6, steel pipe 7 is fixed with in the bottom of suction manifold house steward 6, one end of described push rod 2 is as the force side for jack-up fluid end valve body 5, the other end of push rod 2 is screwed onto the inside of steel pipe 7, seal ring 3 is installed between push rod 2 and steel pipe 7, the screw thread stretching out steel pipe 7 sections at push rod 2 is bolted with nut 1.
Described push rod 2 comprises A shaft part 2-1, B shaft part 2-2, C shaft part 2-3, and the diameter of described A shaft part 2-1 is greater than the diameter of B shaft part 2-2, and the diameter of described B shaft part 2-2 is greater than the diameter of C shaft part 2-3, and the side near A shaft part 2-1 on B shaft part 2-2 is provided with screw thread.
The inside of described steel pipe 7 is disposed with screw thread 7-1, seal groove 7-2 inwards from port.
The seal ring 3 installed between push rod 2 and steel pipe 7 is O RunddichtringO, is arranged in steel pipe in seal groove 7-2, can prevents the leak of liquid in suction manifold.
The push rod 2 stretching out steel pipe 7 end is bolted with nut 1, when nut 1 is tightened with steel pipe 7 end, the effect preventing push rod 2 from loosening can be played.
The overhead-valve mechanism of a kind of high-pressure plunger pump suction manifold of the utility model can be fixed on the bottom of manifold house steward 6 for a long time, when valve body 5 freezes to need top to open, after loosening nut 1 to itself and steel pipe 7 end face has a segment distance, turn clockwise push rod 2, and push rod 2 spiral one segment distance can back down icing valve body 5; After valve body 5 backs down, be rotated counterclockwise push rod 2 and make its reset that declines, now tightened in nut 1 and steel pipe 7 end, when normally working to prevent high-pressure plunger pump, manifold internal liquid produces push rod 2 and impacts, and push rod 2 is loosened.
When the overhead-valve mechanism of a kind of high-pressure plunger pump suction manifold of the utility model needs examine and replace, first nut 1 can be unscrewed, then be rotated counterclockwise push rod 2, unloaded.
