Abstract
The utility model provides a fracturing pump valve lid puller, it includes the three -jaw base, be equipped with the screw on the bedplate of three -jaw base, be equipped with in the screw rather than the complex lead screw, the lead screw is equipped with screw nut in the top of three -jaw base, screw nut's upper portion is equipped with and prevents that the lead screw pivoted from preventing that the favourable turn constructs. The beneficial effects of the utility model are that: compared with the prior art, the utility model discloses be equipped with through three -jaw support base, with spanner rotary screw rod nut, utilize the laborsaving principle of lead screw screw thread, pull out the valve gap with the lead screw. Avoid rough power operation damage equipment, simultaneously, also improved work efficiency.
Description
Technical field
This utility model relates to a kind of fracturing unit truck service kit, particularly a kind of fracturing pump valve gap puller.
Background technology
At present, in actual applications, when fracturing pump inspection, maintenance, repair, fluid end is for mainly overhauling object, and the internal overhaul of fluid end all must take out 6-10 valve gap of dress on pump head body just can carry out next step operation. But, valve gap is by the combination sealing such as rubber ring, O and pump head body interference fit, and valve gap is to sink inside pump head body, so comparatively bothering when taking out. Commercially, most workman is with a screw rod with percussion hammer, by knocking pull-out valve gap back and forth. So operation belongs to brute-force operation, and strength is not easily controlled, and is very easy to be damaged to valve bonnet seal assembly, inefficiency, and is also susceptible to the accident that hands crushes injury, injures by a crashing object during operative during valve gap pull-out.
Utility model content
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide the instrument of a kind of special pull-out fracturing pump valve gap, and it can improve the work efficiency of pull-out valve gap.
The technical solution of the utility model particularly as follows:
A kind of fracturing pump valve gap puller, it includes three-jaw base, and the seat board of three-jaw base is provided with screw, is provided with the leading screw being mated in screw, and leading screw is arranged over feed screw nut three-jaw base; The top of feed screw nut is provided with the rotation-preventing mechanism preventing screw turns.
Described rotation-preventing mechanism is a U-tube, and one end of U-tube is inserted in the through hole of the seat board of three-jaw base, and other end is fixed on the upper end of leading screw by bearing pin.
The end of described bearing pin is provided with split pin.
Described leading screw is fixing outer six square nuts in the lower section of three-jaw base.
The beneficial effects of the utility model are: compared to the prior art, and this utility model is provided with three-jaw and supports base, with spanner rotary screw nut, utilizes the laborsaving principle of wire rod thread, are pulled out by valve gap with leading screw. Avoid brute-force operation injury device, meanwhile, also improve work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is schematic diagram when drawing lid of the present utility model.
Detailed description of the invention
Such as Fig. 1, a kind of fracturing pump valve gap puller, including three-jaw base 7, the seat board of three-jaw base 7 is provided with screw, is provided with the leading screw 3 being mated in screw, and leading screw 3 is arranged over feed screw nut 5 at three-jaw base 7.
For preventing leading screw 3 and feed screw nut 5 from working day and night, the top of feed screw nut 5 is provided with the rotation-preventing mechanism preventing leading screw 3 from rotating.
Rotation-preventing mechanism is a U-tube 1, and one end of U-tube 1 is inserted in the through hole 8 of the seat board of three-jaw base 7, and other end is fixed on the upper end of leading screw 3 by bearing pin 2.
The end of bearing pin 2 is provided with split pin 4.
Leading screw 3 is fixing outer six square nuts in the lower section of three-jaw base 7.
Operation principle is:
Such as Fig. 1-2, during its work, open split pin 4, make U-tube 1 and leading screw 3 depart from. First three supports of three-jaw base 7 are placed on the upper surface of fracturing pump, make leading screw 3 alignment need the valve gap in the fracturing pump 10 of dismounting. Rotating threaded shaft 3 or outer six square nuts, make leading screw 3 threaded with valve gap. After U-tube 1 is connected by bearing pin 2 with leading screw 3, hand steered positive U-tube 1, by spanner 6 rotating threaded shaft nut 5, feed screw nut 5 is had to rotate along with spanner 6, screw mandrel 3 is spacing by U-tube 1 and three-jaw base 7, can only doing rectilinear motion, downwards there is relative motion with leading screw 3 at the axial direction of leading screw 3 in nut 5, touch the upper surface of three-jaw base 7 until nut 5. Continuing rotating threaded shaft nut 5, because nut 5 is stopped can not move downward by three-jaw base 7, leading screw 3 is forced along it moved axially upward, and the valve gap being connected with threads of lead screw also moves upwardly together with leading screw 3, and then valve gap is drawn out.
Rotation-preventing mechanism is designed as U-tube, and operator can grip its bending section by a hands, a hands rotary spanner, convenient operation.
