Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described.
As shown in Figure 1, the utility model proposes a kind of check valve spool extractor, comprise the body of rod 1, one end of the body of rod 1 is fixedly connected with expander 5, the lid 3 that can be fixedly connected with check-valves valve port is arranged with outside the body of rod 1, between expander 5 and lid 3, the outer movable sleeve of the body of rod 1 is provided with expansion sleeve 2, and the external diameter of expansion sleeve 2 is less than the external diameter of lid 3 and the external diameter of expansion sleeve 2 is greater than the internal diameter of lid 3, and the wall of expansion sleeve 2 near expander 5 one end is provided with the gap 201 that can be inflated body 5 and strut.
When using check valve spool extractor of the present utility model to take out check valve spool, only need the gap 201 of expander 5 of the present utility model and expansion sleeve 2 is stretched into and by the other end of spool, then lid 3 and check-valves valve port are fixed, and the body of rod 1 is dropped outside check-valves valve port, expander 5 is along with the gap 201 of the body of rod 1 dilating expansion sleeve 2, expansion sleeve 2 drives and unloads bottom spool in the process of dilatancy, to dismantle lid 3, continue outwards to drop the body of rod 1, namely complete check valve spool and take out action.It can thus be appreciated that, the utility model can take out fast and change rapidly the spool of check-valves, workload significantly reduces, the work alleviating employee is slight, and effectively reduce the cost of repairs of check-valves, meanwhile, also stopped the potential safety hazard that may cause owing to frequently cutting check-valves technique, improve the stationarity of water filling.
In a concrete embodiment, lid 3 is provided with the connecting portion 301 of tubular towards the side of expansion sleeve 2, connecting portion 301 and lid 3 are coaxially arranged, and the internal diameter of connecting portion 301 is greater than the external diameter of expansion sleeve 2, and connecting portion 301 is provided with the internal thread that can be spirally connected with described check-valves valve port.In use procedure, connecting portion 301 and this check-valves are screwed together, and make to form a confined space between this check-valves and lid 3, prevent the overbottom pressure in check-valves from overflowing from the edge of lid 3 and hurt sb.'s feelings.
During in order to avoid taking out check-valves, the overbottom pressure that may retain in valve causes damage to staff, the wall of connecting portion 301 is provided with pressure release through hole 302, with overbottom pressure in drain.Or connect relief tube 303 at pressure release through hole 302, relief tube 303 is positioned at outside connecting portion 301, make overbottom pressure according to relief tube 303 move towards discharge, ensure in the safety of taking out operating personnel in spool process.
At lid 3, screens bulge loop 304 is set towards the side of expansion sleeve 2, screens bulge loop 304 and lid 3 concentric are arranged, the internal diameter of screens bulge loop 304 equals the internal diameter of lid 3, the external diameter of screens bulge loop 304 is less than the internal diameter of expansion sleeve 2, thus makes expansion sleeve 2 can be stuck in the position of screens bulge loop 304 in the process of taking out spool.
Make expander 5 for Rotary-table, but the inwall of expansion sleeve 2 near expander 5 one end is taper seat, described taper seat and expansion sleeve 2 are coaxially arranged, the bottom surface of described taper seat is towards expander 5, the end face of described Rotary-table is towards expansion sleeve 2, so that the gap 201 of expander 5 dilating expansion sleeve 2, the basal diameter of described taper seat is greater than the end face diameter of described Rotary-table, and the basal diameter of described taper seat is less than the basal diameter of described Rotary-table.
As shown in Figure 2, gap 201 is S type so that after pressure distortion, can more effectively support spool so that by valve core taking.In a feasible embodiment, an end wall surface of expansion sleeve 2 is evenly arranged four gaps 201.
The body of rod 1 is provided with sealing ring 6 at the opposite side of lid 3 relative expansion sleeve 2, and lid 3 is close to by sealing ring 6, hurts operating personnel to prevent overbottom pressure in water well stream journey from the mesopore spilling of lid 3.
In a concrete embodiment, the body of rod 1 can be screw rod, and the body of rod 1 is spirally connected with lid 3 and expander 5; The other end of the body of rod 1 is bolted with nut 4, and nut 4 is located at the opposite side of lid 3.The wall of nut 4 offers radial through hole 401, described check valve spool extractor also comprises the spanner 7 by through hole 401 rotating nut 4.During use, can match with the common instrument such as spanner 7, easy-to-use, and operating personnel use spanner 7 at side rotating nut 4, control the movement of the body of rod 1, to ensure the safety of operating personnel.
Illustrate use procedure of the present utility model below, operating procedure is as follows:
1, the standby cap at the check-valves top of blocking is taken off, expose the spool of check-valves;
2, be spirally connected one end of the body of rod 1 (screw rod) expander 5, puts expansion sleeve 2, then stretch into the spool of check-valves, until " S " groove part gap 201 stretches out the other end of spool on expansion sleeve 2 from the other end of the body of rod 1;
3, to be spirally connected lid 3 at the other end of the body of rod 1, and to make lid 3 be spirally connected fixing with the valve of check-valves, then to be spirally connected successively sealing ring 6 and nut 4 at the opposite side of lid 3;
4, spanner 7 is inserted the through hole 401 on nut 4, rotary spanner 7 also makes the body of rod 1 move outside check-valves valve, gap 201 to expander 5 dilating expansion sleeve 2, expansion sleeve 2 deforms, continue rotary spanner 7, expansion sleeve 2 is with movable valve plug to move to check-valves valve port in the process of dilatancy;
5, be inflated after sleeve pipe 2 drives and unload until the spool of check-valves, pull down nut 4, sealing ring 6 and lid 3 successively, taken out by the body of rod 1 in check-valves, spool is taken out of in check-valves by the body of rod 1.
In use, do not need to take off check-valves, operating process is simple and efficient for check valve spool extractor of the present utility model, and in Renewal process, the sealing at valve port place can be ensured, guarantee the safety of operating personnel, do not need to cut in check valve body, maintain the security of check-valves yet.
The foregoing is only the schematic detailed description of the invention of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, the equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.And it should be noted that, each part of the present utility model is not limited in above-mentioned overall applicability, the each technical characteristic described in description of the present utility model can select one to adopt separately or select the multinomial use that combines according to actual needs, therefore, the utility model naturally covers other relevant with this case innovative point and combines and embody rule.
