Abstract
The utility model provides a kind of engineering machinery hydraulic station control valve body, valve body and reinforcement block including split settings, the cavity with media contact is equipped in the valve body, the reinforcement block is set to be cooperated with the cavity in the cavity, the reinforcement block is equipped with threaded hole, and the reinforcement block passes through the threaded hole by bolt and is fixedly connected with the valve body.A kind of engineering machinery hydraulic station provided by the utility model control valve body need to be only individually replaced reinforcement block after reinforcement block abrasion, be reduced production cost using reinforcement block and valve body split settings.
Description
Technical field
The utility model relates to hydraulic station technical fields, more particularly to a kind of engineering machinery hydraulic station control valve valve
Body.
Background technique
Hydraulic station is the hydraulic power source being made of hydraulic pump, drive motor, fuel tank, direction valve, throttle valve, overflow valve etc.
Device or the hydraulic device including control valve.By the flow direction of driving device requirement, pressure and flow fuel feeding, it is suitable for driving
Device separated with hydraulic station it is various mechanically hydraulic station is connected with driving device (oil cylinder or motor) with oil pipe, hydraulic pressure system
Various defined movements can be realized in system.
Control valve (Control valve) is made of two main sub-assemblies: valve body sub-assembly and executing agency combine
Part (or actuator system) is divided into four big series: single seat series of control valves, two-seater series of control valves, sleeve series of control valves
With self-operated type series of control valves.The mutation of four seed type valves can lead to various different applicable structures, every kind of knot
Application that structure has its special, feature, merits and demerits.
For using the control valve in High Pressure Difference and corrosive media occasion, valve interior wall be often subject to medium impact and
Corrosion, to generate loss, influences the use of control valve, and in the prior art, valve body is integrally machined, after valve interior wall loss
Need to change valve body entirety.
Utility model content
The technical problem to be solved by the utility model is in order to overcome the shortcomings in the prior art, the utility model mentions
Valve body is controlled for a kind of engineering machinery hydraulic station.
The utility model solves its technical problem technical solution to be taken: a kind of engineering machinery hydraulic station control
Valve body, valve body and reinforcement block including split settings, the interior cavity being equipped with media contact of the valve body, the reinforcement block are set
Cooperate in the cavity with the cavity, the reinforcement block is equipped with threaded hole, and the reinforcement block is passed through described by bolt
Threaded hole is fixedly connected with the valve body.
Reinforcement block is made of corrosion-resistant, impact resistance alloy, valve body and reinforcement block split settings, after reinforcement block abrasion only
It need to be individually replaced reinforcement block, reduce production cost, reinforcement block is bolted on valve body and is easily installed.
Further, spring is arranged on the bolt, the spring drives the reinforcement block far from the valve body.Medium punching
Spring works as a buffer when hitting reinforcement block, it is possible to reduce noise when control valve works.
Further, medium leaks from reinforcement block threaded hole in order to prevent, is equipped between the bolt and the threaded hole
Sealing ring.
The beneficial effects of the utility model are: a kind of engineering machinery hydraulic station control valve valve provided by the utility model
Body need to be only individually replaced reinforcement block after reinforcement block abrasion, be reduced production cost using reinforcement block and valve body split settings.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the best embodiment of the utility model；
Fig. 2 is the diagrammatic cross-section of A-A in Fig. 1.
In figure: 1, valve body, 2, reinforcement block, 3, bolt, 4, spring.
Specific embodiment
The utility model is described in detail presently in connection with attached drawing.This figure is simplified schematic diagram, only in a schematic way
Illustrate the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Figs. 1-2, a kind of engineering machinery hydraulic station of the utility model control valve body, including split settings
Valve body 1 and reinforcement block 2, are equipped with the cavity with media contact in the valve body 1, the reinforcement block 2 set in the cavity with institute
State cavity cooperation, the reinforcement block 2 be equipped with threaded hole, the reinforcement block 2 by bolt 3 pass through the threaded hole with it is described
Valve body 1 is fixedly connected.
Spring 4 is arranged on the bolt 3, the spring 4 drives the reinforcement block 2 far from the valve body 1.
Sealing ring is equipped between the bolt 3 and the threaded hole.
It is enlightenment, through the above description, relevant work with the above-mentioned desirable embodiment according to the utility model
Personnel can carry out various changes and amendments in without departing from the scope of the utility model completely.This item utility model
Technical scope is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
