Abstract
The utility model provides a special ball valve for testing, and belongs to a ball valve. The special ball valve for testing comprises a ball valve body, a valve ball, an operating knob, a mimeographing collar and an emptying and decompressing device, the mimeographing collar, the ball valve body and a connecting hoop are connected in sequence, the emptying and decompressing device is arranged outside the ball valve body, a pipeline communicated with the emptying and decompressing device is arranged inside the ball valve body, the valve ball is fixed inside the ball valve body through an upper valve seat and a lower valve seat, and the operating knob which can rotate is arranged on one side of the valve ball. The special ball valve for testing is reasonable in structure and easy to connect and operate, and simplifies working procedures of workers. According to the special ball valve for testing, an original structure connected with a ground surface safety valve is replaced by the emptying and decompressing device, so that connection of pipelines is not miscellaneous and messy anymore, and the connection of the pipelines is easy to manage. The special ball valve for testing is high in safety factor and prevents an oil field from pipe injection accidents caused by pressure in a well.
Description
Technical field
The utility model belongs to ball valve, is specially a kind of test ball-valve dedicated.
Background technology
Lubricator valve is the valve for the down-hole, the assembly that to grow be connected to lubricator valve above, the well of longer assembly is pressed many that the well than the lubricator valve below forces down, and these lubricator valves will be connected with underground safety valve usually, in order to have the shut height more than needed of anti-down-hole pressure.Although existing lubricator valve can be tested and by with the pressure that is connected Control Component of ground safety valve, lubricator valve and ground safety valve are connected difficulty large, pipeline is in disorder is not easy management, is easy to occur security incident, causes damage.
Summary of the invention
For the problems referred to above, the utility model provides a kind of test ball-valve dedicated, traditional lubricator valve is connected with ground safety valve detects Control Component pressure and change into and directly be communicated with the emptying pressure device that goes on lubricator valve, the pressure detecting problem that has namely solved the down-hole need not be connected with ground safety valve again.
Test ball-valve dedicated of the present utility model, to be consisted of by ball valve body, valve ball, operation knob, mimeograph box cupling and the emptying pressure device that goes, mimeograph box cupling, ball valve body are connected successively with jointing clip, the outside of ball valve body is provided with emptying pressure device, the inside gone and is provided with and the emptying pipeline that goes pressure device to communicate, valve ball is fixed in ball valve body inside by upper valve base and lower valve base, and a side of valve ball is provided with rotatable operation knob.
As further improvement of the utility model, described ball valve body is fixed the mimeograph box cupling by being threaded with the mimeograph gland.
As further improvement of the utility model, be provided with handle in the both sides of mimeograph gland.
As further improvement of the utility model, ball valve body and jointing clip are threaded connection.
Test ball-valve dedicated of the present utility model is rational in infrastructure, easily connects and operates, and has simplified workman's working programme; The utility model uses the emptying pressure device that goes to replace original structure that is connected with surface safety valve (SSV), and the connection of pipeline is numerous and diverse in disorder like this, and is manageable; The utility model safety factor is high, has prevented from causing the jet pipe accident because of pressure in well on the oil field;
Description of drawings
Fig. 1 is test ball-valve dedicated structural representation.
The specific embodiment
As shown in Figure 1, test ball-valve dedicated of the present utility model, to be consisted of by ball valve body 1, valve ball 2, operation knob 3, mimeograph box cupling 5 and the emptying pressure device 4 that goes, described mimeograph box cupling 5, ball valve body 1 are connected successively with jointing clip 6, the outside of ball valve body 1 is provided with emptying pressure device 4, the inside gone and is provided with and the emptying pipeline 11 that goes pressure device 4 to communicate, valve ball 2 is fixed in ball valve body 1 inside by upper valve base 9 and lower valve base 10, and a side of valve ball 2 is provided with rotatable operation knob 3.
An end of the present utility model is connected with Oilfield Pipelines, and the other end is connected with well head, by rotary manipulation button control ball valve, utilizes the emptying pressure device control valve internal pressure of going.
