Description
Technical field
This utility model is related to counterbalance valve installation tool, specifically a kind of production tree counterbalance valve mounting tool.
Background technology
In the production tree upkeep operation of Oil/gas Well well head, counterbalance valve is important security management and control equipment, by by back pressure
Valve is arranged in the conversion attachment means of tubing hanger or tubing head, so as under the conditions of with pressure without the need for kill-job, to counterbalance valve
Production tree part above is realized maintenance and/or is changed.In the upkeep operation of production tree, the counterbalance valve on production tree is installed,
It is the counterbalance valve mounting tool realization by being connected on lubricator;Shown in Figure 1, the central upper portion of counterbalance valve has company
Hole is connect, there is handling screw thread in the connecting hole, the middle part outer wall of counterbalance valve has installs screw thread and sealing ring, and counterbalance valve is by connecting
The handling screw thread connect on hole is axially connected with mounting tool, and in the presence of mounting tool, counterbalance valve is by outside installation spiral shell
Stricture of vagina and sealing ring are realized being connected, sealing with the corresponding component on production tree, the installation of handling screw thread and outside inside counterbalance valve
Screw thread is reverse thread structure in opposite direction.
Shown in Figure 2, existing counterbalance valve mounting tool includes core body, and the core body has top connection and lower contact;On connect
Head is mainly made up of the radial perforation on core body and the steady pin being fixed in radial perforation, and core body is connected to anti-by steady pin
On jet pipe;Lower contact is the helicitic texture for taking shape in core body bottom and being matched with counterbalance valve connecting hole, and core body is by lower contact
Screw thread be connected with the connecting hole of counterbalance valve.The mounting tool is only installed on counterbalance valve with the helicitic texture taken shape on core body
On production tree, there is a problem of installing not in place, with potential safety hazard, this is because:1. the inside and outside reverse thread of counterbalance valve is tied
Structure directly determines exerting oneself " degree of having " for mounting tool;2. between the corresponding component on the sealing ring and production tree of counterbalance valve
Elastic conjunction structure, directly determines that mounting tool is obtained " making every effort ";As can be seen here, using aforementioned mounting tool by counterbalance valve
It is installed on production tree, its installation is contradiction, firmly little, counterbalance valve installs not in place, firmly greatly, mounting tool and counterbalance valve
Depart from.Thus, based on the structural particularity of production tree counterbalance valve, existing mounting tool cannot be effectively by counterbalance valve in production tree
On carry out it is effective, firm, be reliably mounted to position, have that mounting technique difficulty is big, efficiency is low, difficult quality is controlled, reliability
The technical problems such as difference.
The content of the invention
Goal of the invention of the present utility model is:Structural particularity and prior art for above-mentioned production tree counterbalance valve
It is not enough, there is provided one kind counterbalance valve is convenient, easily, easily and efficiently can be installed on production tree, and installation quality firmly,
Reliable production tree counterbalance valve mounting tool.
This utility model is to realize that the technical scheme that its goal of the invention is adopted is:A kind of production tree uses counterbalance valve erector
Dress, including core body, the core body has the top connection of connection lubricator and the lower contact of connection counterbalance valve, connects under the core body
Head body external diameter is less than the connecting hole internal diameter of counterbalance valve, and the lower contact body is axially equipped with thread bush by card key, described
Thread bush is matched with the connecting hole on counterbalance valve, and the core body above the thread bush is provided with the pin of being wrenched of radial protrusion, described
Be wrenched pin to match with the U-type groove at the top of counterbalance valve, pin to the distance between the thread bush of being wrenched is matched with counterbalance valve
Top U-type groove to connecting hole loads and unloads the distance between screw thread.
The bottom of the core body is provided with the back-up ring spacing to thread bush.
It is described to be wrenched pin by the radial perforation that is opened on core body and extend to the lock-screw in radial perforation and set
It is placed on core body, is wrenched the two ends of pin respectively from the outer wall radial protrusion of core body.
The card key is inlaid in the corresponding keyway between core body outer wall and thread bush inwall.
The beneficial effects of the utility model are:Above-mentioned frock on core body by being axially movable thread bush and spanner pin-shaped
Into two power transmission points being connected with counterbalance valve, so that it is guaranteed that mounting tool can by high pulling torque be effectively transmitted to counterbalance valve,
Counterbalance valve is set effectively and reliably to be installed in place on production tree, whole installation operation is convenient, light, easy, efficient, and installs
Quality can effectively meet design requirement, and fastness and reliability are high;After counterbalance valve is installed in place on production tree, by spiral shell
The axial direction that stricture of vagina is enclosed within core body moves down the U-type groove that spanner pin can just reliably exited at the top of counterbalance valve, grasps finally by spiral
Make just mounting tool and counterbalance valve can easily, easily, effectively be departed from.
