The invention discloses a rigid sealing structure for a water inlet and outlet valve and a high-pressure water cylinder of a supercharger. The rigid sealing structure comprises the high-pressure water cylinder, an oil cylinder end socket, an end, a piston rod, a hydraulic jack, the water inlet and outlet valve, pull rods, pull rod outer nuts and end locking nuts. The oil cylinder end socket and the end are connected with the two ends of the high-pressure water cylinder, the piston rod extends into a cavity of the high-pressure water cylinder, and the hydraulic jack is used for performing pre-tensioning sealing. The face, in contact with the high-pressure water cylinder, of the water inlet and outlet valve is arranged to be the sealed and matched conical face of the water inlet and outlet valve and the high-pressure water cylinder, and the face, in contact with the end, of the water inlet and outlet valve is arranged to be the sealed and matched conical face of the water inlet and outlet valve body and the end. The four pull rods penetrate through the hydraulic jack, and the end is in threaded connection with the oil cylinder end socket. An ejecting rod for driving the hydraulic jack is used for pressing the end, so that the sealed and matched conical face of the water inlet and outlet valve and the high-pressure water cylinder and the sealed and matched conical face of the water inlet and outlet valve and the end are closely matched to form the rigid sealing structure. The rigid sealing structure gets rid of the constraint of the performance of a plastic sealing part, a fault point is reduced fundamentally, and the sealing reliability of the end is ensured under higher pressure.
Description
Technical field
The present invention relates to high-pressure water cutting core component supercharger, more particularly to supercharger Inlet and outlet water valve body and high pressure
Water vat rigidity hard sealing structure.
Background technology
With the development of water-jet technology application, the pressure also more and more higher of water jet, original paper sealing in water jet system
Life and reliability be restriction water jet development a key factor.On the one hand, high pressure water vat and Inlet and outlet water valve body is logical
It is to dispose the high-wearing feature plastic cement sealing member of a set of circulus between with seal form, water under high pressure squeeze sealing member is sent out
Raw elastic deformation, reaches the purpose of sealing, pressure is higher, commutating frequency is faster, and sealing life is shorter；When pressure is higher, exceed
There is plastic deformation in elastic limit of materials, encapsulant itself cannot meet use requirement.On the other hand in order to easy to maintenance,
Existing termination, turnover water body, high pressure water vat generally adopt two kinds of connected forms, and 1. termination and the mutual screw thread of high pressure water vat connect
Connect, advantage is that quality of fit is high, in equipment running process, Inlet and outlet water valve body circumference uniform force, concentricity are high, and sealing member is moulding
Deformation is consistent, and sealing life is long；Shortcoming is in equipment normal course of operation, and threaded high pressure water vat and termination are held simultaneously
By alternation axial tension and radial tension, pressure amplitude is big, and life-time service screw thread fatigue deformation easily causes screw thread and stings
Extremely.Cannot dismantle.Often dismounting also easily causes termination, high pressure water vat thread abrasion and damage and scraps.2. termination and high pressure
Water vat connects pretensions by four pull bars being fixed on cylinder cover, advantage be will not occur thread biting locking and thread abrasion,
The phenomenon damaged.Shortcoming is the pretension by pull bar and nut, and nut is rigidly connected with termination, because rubbing in each nut and termination
Wipe coefficient different, cause pass in and out water one-way valve radial direction heart stress different, in equipment running process, concentricity is low, sealing member
Plastic deformation is inconsistent, and sealing life is short.
In sum, either encapsulant or type of attachment are all that restriction Water jet equipment future development improves
Key factor.
Content of the invention
The technical problem to be solved in the present invention be to provide one kind can in below 600mpa it is ensured that permanent static seal performance,
Cancel plastic cement sealing member, so that Inlet and outlet water valve body is rigidly connected with high pressure water vat, conveniently install, dismantle, keep in repair, safeguard, repeat
The supercharger Inlet and outlet water valve body using and high pressure water vat rigidity hard sealing structure.
The technical scheme is that

The Inlet and outlet water valve body equipped with low pressure water feeding one-way valve assembly, the hydraulic jack as pre- tightening seal to valve module and low pressure water inlet end
Top, pull bar, pull bar outer nut, termination locking nut.Described Inlet and outlet water valve body is arranged in termination, so that high pressure water side is located at
In termination, the low pressure water inlet end of Inlet and outlet water valve body is integrally located in high pressure water vat cavity.Described Inlet and outlet water valve body and high pressure water vat
Contact surface is configured to Inlet and outlet water valve body and the high pressure water vat sealing cooperation conical surface, and Inlet and outlet water valve body and termination contact surface are configured to turnover
Water valve body coordinates the conical surface with end seals.Sequentially pass through tension rod thru-hole the spiral shell set by hydraulic jack, termination with four pull bars
Stricture of vagina is connected to the pull bar screw hole set by oil cylinder seal head.Described pull bar outer nut and termination locking nut difference spinning are in hydraulic pressure thousand
On the pull bar of jin top outside and inner side, adjusting yoke outer nut, make termination and high pressure water vat on same axial line, by hydraulic oil
Input input hydraulic pressure oil, driving hydraulic jack push rod pressed end, promote Inlet and outlet water valve body and high pressure water vat sealing cooperation cone
Face and Inlet and outlet water valve body are snuggly mated to together with the end seals cooperation conical surface, then by the locking of termination locking nut in oil cylinder envelope
On head, constitute supercharger Inlet and outlet water valve body and high pressure water vat rigidity hard sealing structure.
Above-mentioned Inlet and outlet water valve body is arranged in termination, and termination and Inlet and outlet water valve body are gap cooperations, are provided with o type circle and dispose
In the water inlet corresponding groove of left end, Inlet and outlet water valve body right-hand member has Inlet and outlet water valve body and end seals to coordinate the conical surface, in o type circle and
Have and form sealing low pressure intake antrum between Inlet and outlet water valve body and the end seals cooperation conical surface.
The present invention has self-centering feature according to hydraulic jack；Inlet and outlet water valve body and termination, high pressure water vat are the conical surface
Contact, the conical surface has a self-centering feature, jack input hydraulic pressure oil, four pull bars simultaneously uniform stressed it is ensured that drawbar structure
On the premise of advantage, tradition is overcome to tighten nut successively, pull bar discontinuity is it is impossible to ensure lacking of sealing property stability
Point, reduces maintenance work intensity, shortens maintenance time, improves work efficiency；Inlet and outlet water valve body is subject to the high pressure water vat conical surface
External force acts on into rigid hard sealing structure, cancellation periodic replacement plastic cement sealing member, breaks away from the constraint of plastic cement property of sealing piece, from root
One trouble point is reduced on basis it is ensured that under higher pressure, the reliability of end seals, this Structure adaptation scope is wide.
