Embodiment
Further specify embodiments of the invention below in conjunction with accompanying drawing.
Referring to Fig. 3-6, a kind of axial flow pump bottom valve pressure testing device, it comprises bearing 1, and bearing generally has the space of a whole page on supporting leg and the supporting leg, and the bearing upper outside is provided with coaming plate 10.The bearing both upper ends thereof is respectively equipped with left translation oil cylinder 2 and the right oil cylinder 3 of passing; Left translation oil cylinder and right the passing between the oil cylinder are provided with V-type locating piece 4; V-type locating piece top is provided with valve pocket 5; The left translation oil cylinder is respectively equipped with left sealing shroud 6 and right sealing shroud 7 with the right oil cylinder the inner of passing, and the valve pocket outside is provided with clamp system 8; Also be provided with operating valve on the described bearing, operating valve has first connector 11, second connector 12 and handle 13; Be respectively equipped with left joint 14 and right connector 15 on said left sealing shroud and the right sealing shroud; Said left translation oil cylinder is respectively equipped with two left hydraulic tubes 16 and two right hydraulic tubes 17 with right the passing on the oil cylinder; Be respectively equipped with left hydraulic lock 18 and right hydraulic lock 19 on two left hydraulic tubes and the two right hydraulic tubes; Wherein, a left hydraulic tube, a right hydraulic tube and first connector link to each other through first three-way pipe 20; Another left hydraulic tube, another right hydraulic tube and second connector link to each other through second three-way pipe 21.Described valve pocket two ends are provided with two O type seal grooves 9, can strengthen its sealing property like this, improve the precision of measuring.
Referring to Fig. 6, the described left sealing shroud and the right sealing shroud outside also are provided with guide plate 22.Guide plate can be set at the L type.
This device mainly contains following innovation part:
1. have one can change valve pocket in the bottom valve pressure testing device, be used to adapt to the pressure testing of different size bottom valve;
2. for satisfying the high pressure pressure testing, at the two O shape seal grooves of seals at employing of valve pocket;
3. the pressure when being the balance pressure testing has adopted big hydraulic cylinder at the valve pocket two ends, withstands valve pocket;
4. for guarantee that valve pocket can not move when pressure testing, adopted clamp system that it is clamped;
5. during for the assurance pressure testing, pressure is constant, in device, has adopted hydraulic pressure trivial next trivial tight.
This pressure testing device has solved the difficult problem that bottom valve for a long time can not pressure testing, and a pressure testing difficult problem of especially bearing (70Mpa) of high pressure is for the quality problems of meal at the bottom of the outsourcing provide pick-up unit.The amount of considering bottom valve simultaneously is big, and this device adopts handling mode easily and efficiently.
Utilize this device to carry out the pressure testing process: bottom valve 23 to be packed in the valve pocket 5, valve pocket 5 is put into V-type locating piece 4 location, valve pocket is clamped with clamp system 8.Move control valve, left and right sides sealing shroud 6,7 about pass under the promotion of cylinder 2,3, stretch out along guide plate 22 directions, withstand valve pocket, seal up the valve pocket two-port.The emulsion casing is moved the handle 13 of operating valve with after left and right joint is connected, and emulsion returns liquid from left joint feed liquor from right connector, the opening pressure that test bottom valve this moment.Oppositely move the operating valve handle, emulsion returns liquid from the right connector feed liquor from left joint, the closing presure (70Mpa) that test bottom valve this moment, and under the effect of hydraulic lock, voltage stabilizing half a minute.Oppositely move control valve, clamp system 8 is opened in sealing shroud 6,7 withdrawals in the left and right sides, and valve pocket is taken out from pressure testing device, takes out from valve pocket from bottom valve again.So far, accomplished the pressure testing of bottom valve.
Protection scope of the present invention is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and do not depart from the scope of the present invention and spirit the present invention.If these changes and distortion belong in the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and is out of shape interior.
