To cylinder, the axis of spool guide cylinder and valve body on the same line, there is the axis of axis Yu spool guide cylinder in spool guide cylinder
Drum-shaped spool on the same line, the rear end bucket bottom outside of spool is embedded with the seal spool matched with valve seal ring
Ring has barrel to be evenly equipped with the cylinder-shaped of sieve pore and adjusts flow cartridge, spool guiding in valve body, between the rear end and water outlet of spool guide cylinder
There is circular hole slab in front in cylinder, and on the same line, the front of spool has the axis of the circular hole on circular hole slab and spool guide cylinder
The cylinder-shaped guide cylinder matched with circular hole slab, valve body have a valve shaft perpendicular with valve axis, the axis of valve shaft and valve body
Axis intersection, has crank-linkage type device for driving valve body, device for driving valve body has positioning to be connected on valve shaft between valve shaft and spool
Crank, crank is hinged with connecting rod, and connecting rod is hinged on the bucket wall of spool radial direction.
The rotation of valve shaft is become spool axial movement by the crank-linkage type device for driving valve body between valve shaft and spool
Transmission device.In use, driving valve shaft rotation, drives spool to slide axially in spool guide cylinder, changes by crank connecting link
Circulation area and the pipeline rate-of flow or pressure of control valve rear end between seal spool ring and valve seal ring.
Above-mentioned piston fluid regulating valve has following deficiency:
1. valve shaft intersects with the axis of valve body, crank-linkage type device for driving valve body drives spool in spool guide cylinder inner shaft
To when reciprocatingly sliding, although spool can also be generated by axial force, between crank and the hinge joint and valve axis of connecting rod it is larger away from
From, make spool also by biggish radial force, biggish radial force not only increases switch torque, can also make mating surface generate
Abrasion, causes the axis of the axis runout spool guide cylinder of spool, influences the use of piston type regulating valve；
2. spool the guiding device in spool guide cylinder be in spool guide cylinder the circular hole slab of front and spool front with
The cylinder-shaped guide cylinder that circular hole slab matches, structure is complicated for spool guiding device, and steering capability is bad；
3. after running the sieve pore blockade of a period of time dirt or impurity throttling barrel, easy-clear, which is not blocked in, adjusts flow cartridge wall
The dirt or impurity of sieve pore make medium that can not circulate or can not adjust flow.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, propose a kind of radial force that spool can be made to be subject to it is smaller,
Spool guiding device structure is simple, and steering capability is good, is easy to remove the piston for being blocked in the dirt or impurity of adjusting flow cartridge wall sieve pore
Formula flow control valve.
The utility model is realized with the following method.
Piston fluid regulating valve has cylinder valve, and there is water inlet in the front end of valve body, and there are water outlet, valve in the rear end of valve body
There is valve seal ring in body water outlet, the connected drum-shaped spool guide cylinder of useful uniformly distributed radial wing plate, spool are led in valve body
On the same line to the axis of cylinder and valve body, there is the axis of axis and spool guide cylinder in spool guide cylinder on the same line
Drum-shaped spool, embedded with the seal spool ring that is matched with valve seal ring on the outside of the rear end bucket bottom of spool, in valve body, spool
There is barrel to be evenly equipped with the cylinder-shaped of sieve pore between the rear end and water outlet of guide cylinder and adjust flow cartridge, valve body has perpendicular with valve axis
Valve shaft, have crank-linkage type device for driving valve body between valve shaft and spool, device for driving valve body has positioning to be connected on valve shaft
Crank, crank are hinged with connecting rod, and connecting rod is hinged on the bucket wall of spool radial direction,
The axis of valve shaft and the axis of valve body have gap, and spool guide cylinder inner wall even distribution has axially directed band, and guidance tape encloses
At the barrel surface of cylindrical space matched with the barrel surface of spool, corresponding adjust in valve body rear portion is evenly equipped with radial blowdown at flow cartridge
Hole.
The utility model has the following advantages with the piston fluid regulating valve comparison in above-mentioned prior art:
1. the axis of valve shaft and the axis of valve body have gap, crank-linkage type device for driving valve body driving spool is led in spool
Into cylinder axial reciprocating slide when, crank between the hinge joint and valve axis of connecting rod at a distance from reduce, the diameter for being subject to spool
Also reduce to power, reduces to switch torque, to the abrasion of mating surface；
2. spool guide cylinder inner wall even distribution has the mutually axially directed band with spool cooperation, guiding band structure is simple, guiding performance
It can be good；
3. corresponding adjust in valve body rear portion is evenly equipped with radial mudhole at flow cartridge, removing can be easy to by mudhole and be blocked in
Adjust the dirt or impurity of flow cartridge wall sieve pore.
With reference to the accompanying drawing, the utility model is further described.
