Description

Anti-plugging one-way throttle valve
Technical field
The utility model relates to a kind of anti-plugging one-way throttle valve.
Background technique
Throttle valve is by changing throttling cross section or chock length to control the valve of fluid flow, throttle valve then being may be combined with into one-way throttle valve with one-way valve parallel connection.Throttle valve and one-way throttle valve are easy flow control valves, and in hydraulic system with constant displacement pump, throttle valve and relief valve coordinate, and can form three kinds of Metering Flow Control Circuits, i.e. in-line Metering Flow Control Circuits, oil circuit Metering Flow Control Circuits and bypass throttling speed governing system.Throttle valve does not have flow reverse feedback function, can not compensate the speed that caused by load variations unstable, generally only little or to the less demanding occasion of speed stability for load variations.
Existing one-way throttle valve due in fluid unload impurity or because of oxidation separate out than, the dirt accumulation such as pitch, carbon slag in throttle chink, easy generation blocking phenomenon, reduces the working life of throttle valve, needs often to change, reduce working efficiency, increase cost of production.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of anti-plugging one-way throttle valve of long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of anti-plugging one-way throttle valve, there is valve body, the middle position of described valve body is provided with nut, the water inlet of valve body is provided with spring seat, middle position in the cavity of valve body is provided with one-way valve, be provided with spring between one-way valve and spring seat, the joint of valve body water outlet and nut is provided with " O " RunddichtringO, and spring seat and valve body contact place are provided with snap ring.
Further, described valve body adopts alloy material to make, and extends the working life of valve body, increases work efficiency.
Further, described valve inleting water mouth place is provided with filter screen, the mechanical admixture in fluid or because of oxidation separate out the dirt accumulation such as colloid, pitch, carbon slag at throttle chink place, not easily produce blocking, extend the working life of valve body, need not often change, increase work efficiency, reduce cost of production.
Further, the inwall of described valve body is coated with anti-corrosion layer, because medium flow velocity between flap and valve seat is very large, to cause these part surfaces to damage-i.e. so-called cavitation phenomenons very soon, in order to reduce cavitation impact as far as possible.
The beneficial effects of the utility model are: the utility model structure is simple, use and easily manufactured, not easily produce blocking, extend the working life of valve body, often need not change, increase work efficiency, reduction cost of production.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. valve bodies, 2. nut, 3. spring seat, 4. one-way valve, 5. spring in figure, 6. " O " RunddichtringO, 7. snap ring, 8. filter screen, 9. anti-corrosion layer.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of anti-plugging one-way throttle valve as shown in Figure 1, there is valve body 1, the middle position of valve body 1 is provided with nut 2, the water inlet of valve body 1 is provided with spring seat 3, middle position in the cavity of valve body 1 is provided with one-way valve 4, spring 5 is provided with between one-way valve 4 and spring seat 3, the joint of valve body 1 water outlet and nut 2 is provided with " O " RunddichtringO 6, spring seat 3 and valve body 1 contacting point are provided with snap ring 7, valve body 1 adopts alloy material to make, valve body 1 water inlet is provided with filter screen 8, the inwall of valve body 1 is coated with anti-corrosion layer 9.
Concrete hydraulic oil enters from entry port, open one-way valve 4, and flow out from outlet port, the fluid of its gateway will turn back to entry port, now one-way valve 4 is closed under the effect of spring 5, hydraulic oil can only enter into gateway by throttle valve 4, is provided with " O " RunddichtringO between valve body 1 and nut simultaneously, ensures the sealability of valve body, leakage can not be produced, simultaneously structure is simple, uses and easily manufactured, not easily produces blocking, extend the working life of valve body, often need not change, increase work efficiency, reduce cost of production.
Above-mentioned mode of execution is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
