Description
Technical field
The present invention relates to a kind of valve, especially a kind of multistage flow divider valve of changeable range of flow.
Background technique
In dyeing process, the accurate weighing of material and proportioning produce great influence to product coloured light.In process was sized mixing in traditional printing and dyeing, the proportioning weighing of dying material all realized by artificialization material and weighing, exists the inaccurate and slow-footed shortcoming of weighing.
The automatic blended size system of many at present employings improves the precision and the automaticity of weighing, if but use common valve to control the flow of various materials, precision is difficult to control, needs especially to carry out that big flow is reinforced when switching with the small flow fine setting, and common valve is difficult to realize.
Existing flow control valve according to its difference of regulating the critical component of flow section size, can be divided into gate valve, stop valve, ball valve, stopcock etc.A common ground of these valves is: valve opening degree is from large to small the time, and its flow section diminishes gradually, and when little open degree, flow section becomes a slit that width is very little.If bigger impurity of particle or fluid thickness are arranged in the fluid, just cause flow hour valve blockage easily, as contain the chemical industry fluid of particle.Chinese patent 02215108.7 discloses a kind of printing and dyeing distributing head of sizing mixing, and material is not deposited in valve, has guaranteed flowing smoothly of slurry, but owing to adopt two independently valve rods, and a valve rod control small flow, another valve rod is controlled big flow, make the valve volume increase complex structure.
Summary of the invention
The utility model provides a kind of distributing valve that can switch the adjusting mass flow of range of flow, rational in infrastructure, reliable operation.
A kind of multistage flow divider valve, comprise valve body, be set with the outer needle of hollow in the valve body, be set with inner valve needle in the outer needle, in the outer needle, outer wall and valve body and inner valve needle closely cooperate and seal or seal with seal ring, the discharge end inwall of valve body is provided with extending section, the inwall of extending section forms material cavity with the outer wall of outer needle, two materail tubes and material cavity UNICOM, the discharge end termination of the valve body discharge port pressure cap that has been threaded, the outer wall of discharge port pressure cap inwall and outer needle closely cooperates and seals or seal with seal ring, the outer wall axisymmetric of outer needle part in material cavity is provided with two bar shaped perforates, inner valve needle radially is being provided with pin, and pin grows the inner valve needle outer wall section and is defined in the bar shaped perforate.
The inside and outside diameter of the discharge end of described outer needle shrinks gradually and forms the back taper pipeline section, continues the isometrical discharging section that extends to form afterwards.Back taper pipeline section outer wall and discharge port pressure cap inwall closely cooperate and seal or seal with seal ring.
Inner valve needle can move vertically with respect to outer needle, and the stroke of relative movement is promptly sold movable stroke in the bar shaped perforate.Outer needle can move vertically with respect to valve body.
Valve body be with valve pocket outward away from discharge end, valve pocket be provided with annular guide sleeve away from the discharge end internal fixation, stretching out outer needle and extend the mesopore that passes annular guide sleeve away from discharge end of inner valve needle passes part and is provided with the draw ring cover that is used to spur the inner valve needle motion.
The diameter of the discharge end of inner valve needle shrinks gradually and forms the inverted cone section, and inverted cone section shape matches with the inwall of the back taper pipeline section of outer needle, seals by closely cooperating or seals with seal ring.When sealing with seal ring, the outer wall of the inverted cone section of inner valve needle is provided with circular groove, and circular groove is built-in with seal ring.
Outer needle is stretching out valve body away from discharge end, and extension is provided with the big spring back-up ring, and extension and big spring back-up ring are all in valve pocket inside, and extension is fixedlyed connected with the big spring back-up ring.
The big spring back-up ring is connected with big spring, and big spring one end and big spring back-up ring hold out against, and the other end and annular guide sleeve hold out against, and under the effect of big spring, the back taper pipeline section outer wall of outer needle holds out against the discharge port pressure cap) inwall, with the material outlet sealing of valve body.
The part of stretching out outer needle away from discharge end of inner valve needle is provided with the little spring back-up ring, and extension and little spring back-up ring are all in valve pocket inside, and extension is fixedlyed connected with the little spring back-up ring.
The little spring back-up ring is connected with little spring, little spring one end and little spring back-up ring hold out against, and the other end and annular guide sleeve hold out against, under the effect of little spring, the outer wall of the inverted cone section of inner valve needle holds out against the inwall of the back taper pipeline section of outer needle, with the material outlet sealing of outer needle.
The outlet internal thread of discharge port pressure cap is connected with screen, makes material stably outside the expulsion valve.Screen is made up of material channel and inner by-passing parts, and material channel is cylindrical, and by-passing parts comprises the little cylinder that is arranged in the material channel, is arranged with 4 disc between little cylinder outer wall and material channel inwall.
When the multistage flow divider valve of the utility model was not opened, the back taper pipeline section outer wall of outer needle held out against discharge port pressure cap inwall.The outer wall of the inverted cone section of inner valve needle holds out against the inwall of the back taper pipeline section of outer needle.Material can circulate between the material cavity of two materail tubes, valve body, thereby avoids material to deposit in valve.
When need be when the discharge end of multistage flow divider valve be emitted material, at first by draw ring cover pulling inner valve needle, the little spring back-up ring compression little spring of inner valve needle, then the outer wall of the inverted cone section of inner valve needle breaks away from the inwall of the back taper pipeline section of outer needle, outside the inverted cone section moves upward to during the position of the bar shaped perforate of needle, material will be outside the bar shaped perforate enters needle and inner valve needle the gap and discharge valve body by the material outlet of outer needle.
Because the gap of outer needle and inner valve needle is less, the material outlet of outer needle is also smaller, so material is also smaller in the certain pressure down-off.
When the bigger mass flow of needs, continuation is by draw ring cover pulling inner valve needle, because inner valve needle can be pin movable stroke in the bar shaped perforate of inner valve needle with respect to the stroke of outer valve needle movements, when the pin of inner valve needle moves to the upper end of bar shaped perforate, inner valve needle can drive outer needle and together move, this moment, the back taper pipeline section outer wall of outer needle broke away from discharge port pressure cap inwall, and the material outlet of valve body is opened.Not only directly the gap of outer needle and inner valve needle can also be through the discharge of the gap of back taper pipeline section outer wall and discharge port pressure cap inwall by the material outlet discharge of outer needle for material at this moment, and material will increase in the certain pressure down-off like this.
Distributing valve of the present utility model can switch range of flow, rational in infrastructure, reliable operation.
