Abstract
The utility model discloses a special tool for detaching a valve of a feeding pump, and belongs to a mechanical tool. The special tool for detaching the valve of the feeding pump comprises a draw bar, a draw bar nut screwed to the upper portion of the draw bar in a rotation mode, a shoulder-type jaw hook frame which is arranged in the middle of the draw bar and can move up and down along the draw bar, and jaw hooks symmetrically arranged at the two ends of the shoulder-type jaw hook frame, wherein a bottom frustum of the draw bar is arranged at the end of the bottom of the draw bar; the draw bar nut is a hexagonal nut; the shoulder-type jaw hook frame moves up and down between the draw bar nut and the bottom frustum of the draw bar; the shoulder-type jaw hook frame and the jaw hooks are connected through pin nuts, and the jaw hooks rotate with the pin nuts as the axes. The special tool is used for detaching the valve, the height of the draw bar is adjusted by screwing the draw bar nut in the rotation mode, the bottom frustum of the draw bar is made to act on the jaw hooks, and therefore the valve is detached; due to the non-violent detaching mode, not only can the detaching time of the valve be shortened and the labor intensity of maintainers be reduced, but also damage caused in the detaching process of the valve is avoided, and the service life of the valve is prolonged.
Description
Technical field
A kind of feed pump valve tool special for dismounting belongs to machinery tool, is specifically related to a kind of for dismantling the machine tool of feed pump valve.
Background technology
In feed pump, valve and accessory thereof are the parts of easy loss.When valve and accessory thereof are overhauled, valve need to be disassembled, and change the parts that damage.Because valve is close to by rubber seal and valve locular wall, valve is tightly stuck in bonnet, be therefore difficult for manual teardown.
The conventional method of dismounting valve is to knock valve with sliding hammer, this mode is dismantled valve needs the time of about one hour, not only affect feed pump for pump, and waste time and energy, importantly, the valve disassembling there will be to a great extent and by slip, is knocked hammer and knock the problem of damage, can not continue to use, and causes the very large wasting of resources.
Summary of the invention
In order to address the above problem, the utility model has designed a kind of feed pump valve tool special for dismounting, uses the utility model specific purpose tool dismounting valve, not only can shorten the take-down time of valve, reduces maintenance personal's labour intensity; And avoid valve dismounting time to damage, extend the service life of valve.
The purpose of this utility model is achieved in that
A kind of feed pump valve tool special for dismounting, comprises pull bar, screws in the pull-rod nut on pull bar top, is arranged on the shoulder formula claw hook frame sliding up and down along pull bar at pull bar middle part, is symmetricly set on the claw hook at shoulder formula claw hook frame two ends;
Described pull bar bottom end is provided with pull bar base cone platform;
Described pull-rod nut is hex nut;
Described shoulder formula claw hook frame slides up and down between pull-rod nut and pull bar base cone platform;
Between described shoulder formula claw hook frame and claw hook, by pin nut, connect, claw hook is rotated take pin nut as axle.
Above-mentioned a kind of feed pump valve tool special for dismounting, also comprises rubber band, with extended state, is enclosed within on two claw hooks.
Because the utility model feed pump valve tool special for dismounting is by screwing the height of pull-rod nut adjustment pull bar, make pull bar base cone platform act on claw hook, by valve dismounting, this nonviolent dismounting mode, not only can shorten the take-down time of valve, reduce maintenance personal's labour intensity; And avoid valve dismounting time to damage, extend the service life of valve.
Accompanying drawing explanation
Fig. 1 is the utility model sealing box structure schematic diagram.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the top view of Fig. 1.
Fig. 4 is unloading process schematic diagram.
In figure: 1 pull bar, 2 pull-rod nuts, 3 shoulder formula claw hook framves, 4 claw hooks, 5 pull bar base cone platforms, 6 pin nuts, 7 rubber bands, 8 rubber rings, 9 valve bases, 10 pump cylinders, 11 bonnet upper press covers.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model specific embodiment is described in further detail.
The feed pump valve tool special for dismounting of the present embodiment, as shown in Figure 1, Fig. 2 is the left view of Fig. 1 to structural representation, Fig. 3 is the top view of Fig. 1.This feed pump valve tool special for dismounting comprises pull bar 1, screws in the pull-rod nut 2 on pull bar 1 top, is arranged on the shoulder formula claw hook frame 3 sliding up and down along pull bar 1 at pull bar 1 middle part, is symmetricly set on the claw hook 4 at shoulder formula claw hook frame 3 two ends;
Described pull bar 1 bottom end is provided with pull bar base cone platform 5;
Described pull-rod nut 2 is hex nut, can rotate by spanner, and it is moved up and down along pull bar 1 direction;
Described shoulder formula claw hook frame 3 slides up and down between pull-rod nut 2 and pull bar base cone platform 5;
Between described shoulder formula claw hook frame 3 and claw hook 4, by pin nut 6, connect, claw hook 4 is rotated take pin nut 6 as axle.
Schematic diagram when application the utility model feed pump valve tool special for dismounting is dismantled valve base 9 as shown in Figure 4.In figure, valve base 9 acts on pump cylinder 10 by rubber ring 8.When valve base 9 is dismantled, first shoulder formula claw hook frame 3 is moved upward along pull bar 1, make the position of claw hook 4 higher than pull bar base cone platform 5, and cover have rubber band 7 on two claw hooks 4, make two claw hooks 4 for inside deflated state.
Pull down pump housing bonnet upper press cover 11, take out valve gland, valve and spring, because the pump housing is prior art, openly use, and after valve gland, valve and spring are removed, the dismounting feed pump valve seat that need to implement with the utility model no longer includes relation, therefore in Fig. 4, does not draw taken out valve gland, valve and spring.
Feed pump valve tool special for dismounting is goed deep in bonnet, claw hook 4 is deep into valve base 9 position below, will on pull bar 1, move, pull bar base cone platform 5 is contacted with claw hook 4 and make claw hook 4 hook jail valve bases 9.
Put bonnet upper press cover 11, screw pull-rod nut 2, make pull bar 1 drive pull bar base cone platform 5 to move upward, pull bar base cone platform 5 acts on claw hook 4, and valve base 9 is pulled out to bonnet.
Through checking, use the utility model feed pump valve tool special for dismounting dismounting valve, take-down time foreshortens to 5-8 minute for 60 minutes from conventional method, has greatly shortened the take-down time, has significantly reduced maintenance personal's labour intensity, the method that this practicality specific purpose tool carries out valve dismounting simultaneously, not very stiff and demanding violence dismounting, avoided valve due to the impaired problem of violence yet, extended the service life of valve, can save every year 15 of accessories, indirect benefit reaches more than 2000 yuan.
In addition, the utility model feed pump valve tool special for dismounting also has small and exquisite flexible, is easy to learning manipulation, the advantage that Practical Performance is good.
