Abstract
The utility model discloses an overload oil-adding valve for a multi-way valve which is provided with a combined screw nut 3, a pressure adjusting screw nail 4, a poppet valve seat 5, a poppet valve 10, a pressure adjusting spring 9, a spring 11, a conical valve 12 and a slide valve 13. The utility model is characterized in that the poppet valve seat 5 is connected with an integral sleeve barrel; the conical valve 12 is arranged on a valve seat at the front end of the conical valve 12; the rear part of the conical valve 12 is provided with an inner hole which is matched with the outer surface of the front end of the poppet valve seat 5 in a sliding way.
Description
The utility model relates to the hydraulic element in the hydraulic machinery, particularly the relief valve formula overload Fill valve of the integral multi-way valve in the hydraulic element.
The relief valve formula overload Fill valve of prior art must have a bell tap in the outside of valve pocket, and the axial dimension of valve is bigger, and simultaneously, processing and assembly precision are had relatively high expectations, and the concentricity requirement that valve pocket cooperates with cone valve is difficult for guaranteeing that materials consumption is also bigger.Open and be not more than 90% than generally, the up-to-standard rate maximum of once mounting also is no more than 85%.Along with the increase of working pressure with to the raising of equipment precision requirement, need improve existing valve.The purpose of this utility model has promptly been proposed.
The purpose of this utility model is in order to overcome the deficiency of prior art, to provide a kind of integral multi-way valve with transshipping Fill valve.
The purpose of this utility model realizes according to structure described below, this integral multi-way valve is with transshipping Fill valve, has assembled nut 3, pressure regulating screw 4, poppet valve seat 5, poppet valve 10, pressure adjusting spring 9, spring 11 and cone valve 12, the multi-way valve of guiding valve 13 is characterized in that with the overload Fill valve bell tap 7 that is connected with poppet valve seat 5 is sleeves of an one, and cone valve 12 is installed on the valve seat of its front end, at the rear portion of cone valve 12 are endoporus, and the front end outer surface of this endoporus and poppet valve seat 5 is slidingly matched.
The utility model has the advantages that bell tap 7 is structures of an one, compact structure, the original valve of volume ratio reduces 1/3rd, processing and assembly precision require lower, the once mounting up-to-standard rate is about 95%, and cone valve 12 cooperates assembling with poppet valve, and concentricity is higher, therefore open than can also saving valve body material simultaneously up to 94%.
The following drawings explanation, accompanying drawing is a structure sectional view of the present utility model, the sequence number of each component in the accompanying drawings is: 1, lead sealing, 2, protective housing, 3, assembled nut, 4, pressure regulating screw, 5, poppet valve seat, 6, O-ring seals, 7, bell tap, 8, O-ring seals, 9, pressure adjusting spring, 10, poppet valve, 11, spring, 12, cone valve, 13, guiding valve, 14, back-up ring, 15, O-ring seals.
Below in conjunction with the specific embodiment in the accompanying drawing, describe the utility model in detail.With reference to accompanying drawing, this accompanying drawing is the whole sectional view of integral multi-way valve with the overload Fill valve, and the left end of figure is the protective housing 2 by lead sealing 1 sealing.The inside of protective housing 2 has assembled nut 3, and assembled nut 3 and pressure regulating screw 4 and poppet valve seat 5 cooperate, and by pressure adjusting spring 9, adjust the cracking pressure of poppet valve 10.Spring 11 of the front end of poppet valve 10 is pressed on guiding valve 13 in the valve opening of cone valve 12.The bell tap 7 that is connected with poppet valve seat 5 has 6 sealings of an O-ring seals.This bell tap is the sleeve of an one, and its front end has a valve seat, and cone valve 12 promptly is installed on this valve seat, and an endoporus is arranged at the rear portion of cone valve 12, and the front end outer surface of this endoporus and poppet valve seat 5 is slidingly matched.In use, oil pressure just often, cone valve 12 is pressed on the valve seat of bell tap 7 under the effect of more weak spring 11 and oil pressure.When the oil pressure in the P chamber surpasses the set pressure of poppet valve 10; poppet valve 10 is opened; the flow through central through bore of guiding valve 13 of oil; because its damping function is little; make P ' chamber oil pressure a little less than P chamber oil pressure; guiding valve 13 is promptly under this differential pressure action; overcome the active force of more weak spring 11 and move to left; up to being close to poppet valve 10; at this moment; poppet valve 10 blocks the center hole of guiding valve 13, and oil can only flow in the same crack between the sliding valve hole of guiding valve and cone valve, and the damping function of this gap is bigger than the damping function of guiding valve center hole; thereby P ' chamber oil pressure reduces rapidly; cone valve is just opened rapidly under the effect of P and P ' chamber pressure reduction, and pressure oil is let out and got back to oil back chamber T, thereby plays a protective role.When P chamber oil pressure was lower than T chamber oil pressure, cone valve 12 was opened under the effect of this pressure reduction just as common one-way valve, thereby realized from the repairing of T chamber.The effect of seal ring 8,15 and back-up ring 14 is when assembling and the multi-way valve fitted seal.
