Abstract
This utility model provides the internal position limiting structure of a kind of dismountable flushing valve, and including valve seat, adjusting screw rod one end screws in inside valve seat, and the adjusting screw rod other end is provided with locking nut, and locking nut is fitted with valve seat end face.During assembling, apply inward turning yawning moment and make adjusting screw rod screw in the satisfied design requirement of the degree of depth within valve seat, then locking nut is screwed on adjusting screw rod outer end, until locking nut end face is fitted completely with valve seat end face, then applies locking torque to locking nut.During dismounting, applying to unclamp moment to locking nut, continuing by applying moment direction rotational lock nut until there is certain interval between its end face and valve seat end face;Then adjusting screw rod is applied outward turning yawning moment until adjusting screw rod completely disengages from valve seat.This utility model overcomes the deficiency that existing flushing valve part cannot be dismantled, simple in construction, convenient disassembly, reduces flushing valve after-sales service and maintenance cost, improves the service efficiency of complete machine running motor and uses quality.
Description
Technical field
This utility model relates to the internal position limiting structure of a kind of dismountable flushing valve, belongs to enclosed running motor parts
Technical field of structures.
Background technology
Enclosed running motor is mainly used in the travel driving system of sliding loader and other engineering machinery, is walking
The important component part of drive system.In travel driving system, enclosed pump provide running motor working hydraulic pressure
Oil, by oil line pipe, hydraulic oil acts on running motor radial piston, and drive shaft rotates, it is achieved perform
The corresponding action of element, thus meet operator's action request to executive component.
Flushing valve is one of important ingredient of enclosed running motor.Flushing valve structure in the market such as figure
Shown in 1, when seal receptacle 1-3 is by oil liquid pressure, in order to limit the position of seal receptacle motion, at valve seat 1-1
It is provided with the inner circle groove of equipped certain specification elastic spring 1-2, utilizes elastic spring 1-2 to simultaneously act on close
Envelope seat 1-3 and valve seat 1-1 realizes limiting seal receptacle 1-3 movement position.Due to the special construction of elastic spring,
It is difficult to dismounting after valve seat inner circle groove when elastic spring loads, thus has influence on the disassembling and in assembly of seal receptacle
The dismounting of portion's part, brings the biggest difficulty to the maintenance and repair of parts.
Utility model content
The technical problem being flushing valve inner body difficulty and dismantling to be solved in the utility model.
In order to solve above-mentioned technical problem, the technical solution of the utility model is to provide a kind of dismountable flushing valve
Internal position limiting structure, it is characterised in that: including valve seat, adjusting screw rod one end screws in inside valve seat, adjusting screw rod
The other end is provided with locking nut, and locking nut is fitted with valve seat end face.
Preferably, described adjusting screw rod is threaded connection with valve seat.
Preferably, described adjusting screw rod is threaded connection with locking nut.
Preferably, described adjusting screw rod is designed with and is easy to apply hexagonal hole in Torque-adjusting online.
Preferably, the design of described locking nut is easy to apply outer six sides of locking torque.
During assembling flushing valve, act in adjusting screw rod six sides first with die nut and apply inward turning direction force
Locking nut, until adjusting screw rod screws in the degree of depth within valve seat and meets design requirement, is then screwed into regulation by square
On screw rod outer end, until fitting completely with valve seat left side in locking nut right side, then apply to set to locking nut
The locking torque that meter requires.
During dismounting flushing valve, first apply to unclamp moment to locking nut, then proceed to by applying the rotation of moment direction
Until there is certain gap between its right side and valve seat left side in twist lock jack panel;Then die nut is utilized
Act in adjusting screw rod six sides and apply outward turning yawning moment until adjusting screw rod completely disengages from valve seat.
This utility model overcomes the deficiency that existing flushing valve part cannot be dismantled, simple in construction, convenient disassembly,
Reduce flushing valve after-sales service and maintenance cost, improve the service efficiency of complete machine running motor and use quality.
Accompanying drawing explanation
Fig. 1 is the internal position limiting structure schematic diagram of conventional flush valves;
The internal position limiting structure schematic diagram of dismountable flushing valve that Fig. 2 provides for the present embodiment.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.Should be understood that these embodiments are only used for
This utility model is described rather than limits scope of the present utility model.In addition, it is to be understood that reading this practicality
After the content of novel instruction, this utility model can be made various changes or modifications by those skilled in the art, this
A little equivalent form of values fall within the application appended claims limited range equally.
The internal position limiting structure schematic diagram of dismountable flushing valve that Fig. 1 provides for the present embodiment, described is detachable
The internal position limiting structure of flushing valve be made up of valve seat 2-1, adjusting screw rod 2-2 and locking nut 2-3.It is relative
Change in the traditional structure shown in Fig. 1 is: valve seat cancels dress elastic spring inner circle groove, at the base of former length
Extend certain length on plinth, and on the basis of original inner cylinder face, add a female thread;Newly-increased tune
Joint screw rod and locking nut;Cancel elastic spring.
Adjusting screw rod 2-2 one end screws in inside valve seat 2-1, and the adjusting screw rod 2-2 other end is provided with locking nut
2-3, locking nut 2-3 fit completely with valve seat 2-1 end face.
Valve seat 2-1 is designed with female thread, it is ensured that adjusting screw rod 2-2 can screw in flexibly.
Adjusting screw rod 2-2 is designed with interior hexagonal hole, it is simple to apply Torque-adjusting.
Locking nut 2-3 is designed with outer six sides, it is simple to apply locking torque.
During assembling flushing valve, act in adjusting screw rod 2-2 six sides first with die nut and apply inward turning side
To moment until adjusting screw rod 2-2 screws in the degree of depth within valve seat 2-1 and meets design requirement, then by locking screw
Female 2-3 is screwed on adjusting screw rod 2-2 outer end, until locking nut 2-3 right side and valve seat 2-1 left side
Fit completely, then apply the locking torque that design requires to locking nut 2-3.
During dismounting flushing valve, first apply to unclamp moment to locking nut 2-3, then proceed to by applying moment side
To rotational lock nut 2-3 until there is certain gap between its right side and valve seat 2-1 left side;Then
Utilize die nut to act in adjusting screw rod 2-2 six sides and apply outward turning yawning moment until adjusting screw rod 2-2
Completely disengage from valve seat 2-1.Flushing valve inner body just can well be dismantled.So flushing valve inner body
The problem that cannot dismantle solves the most up hill and dale.
