Description
Technical field
The present invention relates to high-pressure water cutting core component pressurized machine, particularly relate to pressurized machine water inlet and outlet valve body and high pressure water vat rigidity hard sealing structure.
Background technique
Along with the development of water-jet technology application, the pressure of water jet is also more and more higher, and in water jet system, the life and reliability of original paper sealing is a key factor of restriction water jet development.
On the one hand, the general seal form of high pressure water vat and water inlet and outlet valve body settles the high wear resistance plastic cement Sealing of a set of ring structure between, and high pressure water squeeze sealing member generation resiliently deformable, reaches the object of sealing, pressure is higher, commutating frequency is faster, and sealing life is shorter; When pressure is higher, exceed elastic limit of materials generation plastic deformation, sealing material itself cannot meet usage requirement.On the other hand in order to easy to maintenance, existing termination, turnover water body, high pressure water vat adopt two kinds of connected forms usually, 1. termination is threaded mutually with high pressure water vat, advantage is that quality of fit is high, in equipment running process, water inlet and outlet valve body circumference uniform force, concentricity are high, Sealing plastic deformation is consistent, and sealing life is long; Shortcoming is in equipment normal course of operation, and alternation axial tension and radial tension are born in the high pressure water vat be threaded and termination simultaneously, and pressure amplitude is large, and the fatigue deformation of Long-Time Service screw thread, easily causes thread biting locking.Cannot dismantle.Frequent dismounting also easily causes termination, high pressure water vat thread abrasion and damage and scraps.2. termination is connected pretension with high pressure water vat by four pull bars be fixed on cylinder cover, and advantage is the phenomenon that thread biting locking and thread abrasion, damage can not occur.Shortcoming is the pretension by pull bar and nut, and nut and termination are rigidly connected, due to each nut and termination friction factor different, cause water inlet and outlet one-way valve footpath centripetal stressed different, in equipment running process, concentricity is low, Sealing plastic deformation is inconsistent, and sealing life is short.
In sum, the key factor that restriction Water jet equipment future development that to be sealing material or Connecting format be all improves.
Summary of the invention
The technical problem to be solved in the present invention is, there is provided one can at below 600Mpa, ensure permanent static seal performance, cancel plastic cement Sealing, water inlet and outlet valve body and high pressure water vat are rigidly connected, convenient installation, dismounting, maintenance, maintenance, reusable pressurized machine water inlet and outlet valve body and high pressure water vat rigidity hard sealing structure.
The technological scheme adopted is:
Pressurized machine water inlet and outlet valve body and high pressure water vat rigidity hard sealing structure, comprise high pressure water vat, the oil cylinder seal head be connected with high pressure water vat two ends and termination, the piston rod stretched in high pressure water vat cavity, go out water one-way valve joint water inlet and outlet valve body, the hydraulic jack as pre-tightening seal, pull bar, pull bar outer nut, the termination locking nut that high pressure water outlet check valve assembly and low pressure feed-water end are equipped with low pressure water feeding one-way valve assembly is housed.Described water inlet and outlet valve body is arranged in termination, makes high pressure waterexit end be positioned at termination, and the low pressure feed-water end entirety of water inlet and outlet valve body is arranged in high pressure water vat cavity.Described water inlet and outlet valve body and high pressure water vat surface of contact are configured to water inlet and outlet valve body and high pressure water vat and are sealed and matched the conical surface, and water inlet and outlet valve body and termination surface of contact are configured to water inlet and outlet valve body and coordinate the conical surface with end seals.With four pull bars successively through hydraulic jack, tension rod thru-hole set by termination the pull bar screw hole be threaded in set by oil cylinder seal head.Described pull bar outer nut and termination locking nut difference spinning are outside hydraulic jack and on the pull bar of inner side, regulating tie bar outer nut, make termination and high pressure water vat on same shaft axis, by hydraulic oil input end input hydraulic pressure oil, drive hydraulic jack push rod pressed end, the be sealed and matched conical surface and water inlet and outlet valve body and end seals of water inlet and outlet valve body and high pressure water vat is impelled to coordinate together with the conical surface closely cooperates, locked on oil cylinder seal head by termination locking nut again, form pressurized machine water inlet and outlet valve body and high pressure water vat rigidity hard sealing structure.
Above-mentioned water inlet and outlet valve body is arranged in termination, termination and water inlet and outlet valve body are Spielpassung, being provided with O type circle is placed in in the corresponding groove of water left end, water inlet and outlet valve body right-hand member has water inlet and outlet valve body to coordinate the conical surface with end seals, at O type circle with have water inlet and outlet valve body to coordinate between the conical surface with end seals to form sealing low pressure water-inlet cavity.
The present invention has self-centering feature according to hydraulic jack; Water inlet and outlet valve body and termination, high pressure water vat are taper-face contact, the conical surface has self-centering feature, jack input hydraulic pressure oil, four pull bars uniform stressed simultaneously, under ensureing the prerequisite of drawbar structure advantage, overcome tradition fastening nut successively, pull bar discontinuity, the shortcoming of sealability stability cannot be ensured, reduce maintenance work intensity, shorten engineering time, improve working efficiency; Water inlet and outlet valve body becomes rigidity hard sealing structure with the high pressure water vat conical surface by External Force Acting, cancel and regularly replace plastic cement Sealing, break away from the constraint of plastic cement property of sealing piece, fundamentally reduce by a fault point, guarantee more under high pressure, the reliability of end seals, this Structure adaptation scope is wide.
