The utility model purpose is to provide a kind of water supply well wellhead assembly, and it can solve existing problem in background technology effectively.

In order to solve existing problem in background technology, it comprises the wellhead flange 1 be arranged on well head, peg graft and be fixed with double male joint 2 in the middle part of this wellhead flange 1, the upper end of this double male joint 2 is connected with wellhead manifold 3, described wellhead flange 1 extends upward a circle pipe hanger 4 with the periphery of the junction laminating double male joint 2 of double male joint 2, these pipe hanger 4 upper ends extend near the upper end of junction of wellhead manifold 3 and pipe hanger 4, the other end of described wellhead manifold 3 is connected with pressure measurement manifold 5 by pipeline, on this pressure measurement manifold 5, pressure valve group 6 is installed, the other end of described pressure measurement manifold 5 is equipped with Tiny Drag Slow Shut Check Valves 7, the other end of this Tiny Drag Slow Shut Check Valves 7 is connected with diversion three-way 8 by pipeline, the end that described diversion three-way 8 distributes is connected with steel gate valve 10 with magnetoelectricity eddy-current flowmeter 9 by pipeline, the other end of this steel gate valve 10 is discharged through the first one way valve 11 by pipeline, the other end that described diversion three-way 8 distributes is connected with gate valve 12 by pipeline, the other end of this gate valve is discharged through the second one way valve 13 by pipeline.

Owing to having adopted above technical scheme, the utlity model has following beneficial effect: simple in structure, household metering easy to use, easy to operate, safe and reliable, the outward appearance novelty, can effectively improve its whole application life, and noise is lower, anti-seismic performance is higher.

The accompanying drawing explanation

In order to be illustrated more clearly in the utility model, below in conjunction with accompanying drawing, embodiment is briefly described.

Fig. 1 is structural representation of the present utility model;

Wherein:

1. wellhead flange; 2. double male joint; 3. wellhead manifold; 4. pipe hanger; 5. pressure measurement manifold; 6. pressure valve group; 7. Tiny Drag Slow Shut Check Valves; 8. diversion three-way; 9. magnetoelectricity eddy-current flowmeter; 10. steel gate valve; 11. the first one way valve; 12. gate valve; 13. the second one way valve.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, the accompanying drawing below in conjunction with in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment.

Referring to Fig. 1, this specific embodiment is to be achieved by the following technical solutions, it comprises the wellhead flange 1 be arranged on well head, peg graft and be fixed with double male joint 2 in the middle part of this wellhead flange 1, the upper end of this double male joint 2 is connected with wellhead manifold 3, described wellhead flange 1 extends upward a circle pipe hanger 4 with the periphery of the junction laminating double male joint 2 of double male joint 2, these pipe hanger 4 upper ends extend near the upper end of junction of wellhead manifold 3 and pipe hanger 4, the other end of described wellhead manifold 3 is connected with pressure measurement manifold 5 by pipeline, on this pressure measurement manifold 5, pressure valve group 6 is installed, the other end of described pressure measurement manifold 5 is equipped with Tiny Drag Slow Shut Check Valves 7, the other end of this Tiny Drag Slow Shut Check Valves 7 is connected with diversion three-way 8 by pipeline, the end that described diversion three-way 8 distributes is connected with steel gate valve 10 with magnetoelectricity eddy-current flowmeter 9 by pipeline, the other end of this steel gate valve 10 is discharged through the first one way valve 11 by pipeline, the other end that described diversion three-way 8 distributes is connected with gate valve 12 by pipeline, the other end of this gate valve is discharged through the second one way valve 13 by pipeline.

Described Tiny Drag Slow Shut Check Valves 7 is compared with existing swing check valve, carries every kiloton water 15-25 degree that can economize on electricity.Because the back segment that utilizes Tiny Drag Slow Shut Check Valves 7 shutdown systems to adopt is closed damping mechanism, by the mode that delays to close to the water of stream to earial drainage in system, valve plate is followed first speed and is closed rear Slow Close, thereby the hydraulic pressure impact force while greatly reducing termination of pumping to stream, eliminate the generation of destructive water hammer peak value, improved application life; And damping, wear-resistant, long service life, compare with existing swing check valve, improves 5-7 times of application life, operate steadily, friction, noise is low.
