Description
Technical field
The utility model is related to a kind of hand rotary valves with the limit of built-in handle, belong to hand-operated direction valve designing technique
Field.
Background technology
Hand rotary valve is often used in hydraulic control system, is used for the flow direction of manual control hydraulic oil.Existing hand
Turn valve arrangement is unreasonable, the limited post to handle be it is exposed connect outside with valve body, when installation, is easy to be severed,
Handle is also easy to fall off in position column of frequent pot life, to cause the service life of valve to reduce；Also, this structure is without in
Position commutation position location, reset when, do not have position sense.
Utility model content
According to the above-mentioned deficiencies in the prior art, the technical problems to be solved in the utility model is：It provides a kind of with interior
The hand rotary valve of formula handle limit is set, it is simple and durable to the position limiting structure of handle, and middle position accurate positioning, reset position sense
It is relatively strong.
Hand rotary valve described in the utility model with the limit of built-in handle, including valve body, spool and handle,
In, the rear and front end of valve body is respectively equipped with valve body protecgulum and valve body rear cover, and the front end of spool is equipped with one through its radial positioning
Hole, location hole is interior to be equipped with retaining spring, and the both ends of retaining spring are equipped with positioning ball, and valve body protecgulum is equipped with and two positioning ball phases
Corresponding bayonet, the rear end of spool be equipped with one covered after its radial spacer pin, valve body be fixed with it is corresponding with spacer pin
Block.
Above-mentioned bayonet is the through-hole through valve body protecgulum radial direction, simple for process.
Above-mentioned positioning ball is steel ball, and hardness is high, intensity is big, long lifespan.
Operation principle and process：
In use, two positioning balls are just connected under the action of retaining spring in two bayonets on valve body protecgulum, this
When, handle is in middle position, and when to the first commutation position rotational handle, location hole and spacer pin are with valve core rotation, before valve body
Under lid squeezing action, two positioning ball compression set springs are taken in location hole, completely when rotational handle to spacer pin and block connects
When touching, the positioning to handle at the first commutation position is completed；When rotating backward handle, location hole and spacer pin are anti-with spool
Turn, when go to location hole and bayonet to it is corresponding when under the action of retaining spring, two position balls is caught in bayonet again, in completion
Position resets；It is consistent when principle is with handle the first commutation position of steering when to the second commutation position rotational handle.
Possessed advantageous effect is the utility model compared with prior art：
Hand rotary valve described in the utility model with the limit of built-in handle, using the built-in limit side to handle
Formula, it is simple in structure durable, effectively extend the service life of valve；Also, it is positioned with position in bayonet cooperation progress by positioning ball,
Not only accurate positioning, and position sense is stronger.

Specific implementation mode
The embodiments of the present invention are described further below in conjunction with the accompanying drawings：
As shown in Figures 1 to 7, the hand rotary valve described in the utility model with the limit of built-in handle, including valve body
1, spool 4 and handle 10, wherein the rear and front end of valve body 1 is respectively equipped with valve body protecgulum 9 and valve body rear cover 3, the front end of spool 4
It is equipped with retaining spring 7 in its radial location hole 6, location hole 6 equipped with one, the both ends of retaining spring 7 are equipped with positioning ball
5, valve body protecgulum 9 is equipped with bayonet 8 corresponding with two positioning balls 5, and the rear end of spool 4 is equipped with one through its radial spacer pin
2, block corresponding with spacer pin 2 11 is fixed on valve body rear cover 3.
In preferred embodiment：Bayonet 8 is the through-hole through 9 radial direction of valve body protecgulum, simple for process；Positioning ball 5 is steel ball, firmly
Degree is high, intensity is big, long lifespan.
In use, two positioning balls 5 are just connected under the action of retaining spring 7 in two bayonets 8 on valve body protecgulum 9,
At this point, handle 10 is in middle position, when to the first commutation position rotational handle 10, location hole 6 and spacer pin 2 are with 4 turns of spool
Dynamic, under the squeezing action of valve body protecgulum 9, two positioning 5 compression set springs 7 of ball are taken in location hole 6, completely when rotation hand
When handle 10 to spacer pin 2 and block 11 contacts, the positioning to handle 10 at the first commutation position is completed；When rotating backward handle
When 10, location hole 6 and spacer pin 2 are inverted with spool 4, when go to location hole 6 and bayonet 8 to it is corresponding when retaining spring 7 effect
Under, two positioning balls 5 are caught in again in bayonet 8, and position resets in completion；When to the second commutation position rotational handle 10, principle
It is consistent when with the first commutation position of steering of handle 10.
Hand rotary valve described in the utility model with the limit of built-in handle, using the built-in limit to handle 10
Mode, it is simple in structure durable, effectively extend the service life of valve；Also, by positioning ball 5 and position in the cooperation progress of bayonet 8
Positioning, not only accurate positioning, and also position sense is stronger.
