Description
Technical field
The utility model relates to a kind of novel throttling stop emptying valve.
Background technique
Choke stop evacuation valve is a kind of novel throttling, cut-off, emptying product, closed circuit device made by the pipeline being widely used in oil, rock gas, coal gas, liquefied petroleum gas and oil refining, airport, Oil & Gas Storage etc., therefore, the working environment of choke stop evacuation valve is all poor, and also can be higher to the requirement of itself, particularly the persistency of choke stop evacuation valve work and stability, particularly important.
Choke stop evacuation valve in the course of the work, generally can be subject to the impact of two aspects, one is that outside rugged environment corrodes it, and existing choke stop evacuation valve is all generally adopt metal as its base shell, be easy to the acidity or the alkali matter corrosion that are subject to soil or other sources, and the thermal conductivity of metallic material is relatively good, the temperature of valve inner synchronously can change along with the temperature variation of outside, change more responsive, excessive temperature differentials is easy to affect inner water conservancy diversion situation, and adopt metallic material, the weight of choke stop evacuation valve own can be made very heavy, both transhipment had been not easy to, also installation and maintenance are not easy to, two is that valve inner can be mixed into impurity unavoidably by long-term water conservancy diversion work, thus the sealing that the sealing having influence on flap is connected with gateway, valve body two ends, thus affect persistency and the stability of whole valve working.
Model utility content
The technical problems to be solved in the utility model is: large in order to overcome prior art valve own wt, transhipment is installed inconvenient, operation duration is poor, fragile, easily there is the deficiency blocked in inner passage, provides a kind of own wt comparatively light, corrosion-resistant, influence of temperature change is little, the novel throttling stop emptying valve that water conservancy diversion is stable.
The utility model solves the technological scheme that its technical problem adopts: a kind of novel throttling stop emptying valve, comprise valve body, flap, valve gap, valve rod and handwheel, described flap is arranged in valve body, flap both sides are respectively equipped with flow channel and flow pass, communication port is provided with below described flap, described flow channel is communicated with by communication port with flow pass, below described communication port, correspondence is provided with cylindrical filter screen, the diameter of described filter screen is greater than the diameter of communication port, composite material protective layer is provided with outside described valve body, described valve gap and handwheel are made by composite material.
In order to make filtering effect better, described filter screen upper end and communication port place against, filter screen lower end is fixed on
Body base.
In order to make protective layer anticorrosion ability better, described protective layer is glass fiber reinforced plastics composite material.
The beneficial effects of the utility model are: this novel throttling stop emptying valve passes through at valve body outer installment composite material protective layer; effectively valve body is protected; improve anti-corrosion capability; and by the change of temperature transfer medium; reduce the impact of low temperature on valve body; valve gap and handwheel adopt composite material as making material, alleviate the weight of whole valve, are convenient to transhipment and install.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of novel throttling stop emptying valve of the present utility model;
In figure: 1. valve body, 2. flap, 3. valve gap, 4. valve rod, 5. handwheel, 6. filter screen, 7. flow channel, 8. flow pass, 9. protective layer, 10. communication port.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1; a kind of novel throttling stop emptying valve; comprise valve body 1, flap 2, valve gap 3, valve rod 4 and handwheel 5; described flap 2 is arranged in valve body 1; flap 2 both sides are respectively equipped with flow channel 7 and flow pass 8; communication port 10 is provided with below described flap 2; described flow channel 7 is communicated with by communication port 10 with flow pass 8; below described communication port 10, correspondence is provided with cylindrical filter screen 6; the diameter of described filter screen 6 is greater than the diameter of communication port 10; be provided with composite material protective layer 9 outside described valve body 1, described valve gap 3 and handwheel 5 are made by composite material.
In order to make filtering effect better, described filter screen 6 upper end and communication port 10 place are against, filter screen 6 lower end
Be fixed on bottom valve body 1.
In order to make protective layer 9 anticorrosion ability better, described protective layer 9 is glass fiber reinforced plastics composite material.
Composite material is compared to metallic material, lighter in weight, and it is less by acid and alkali corrosion degree, adopt glass fiber reinforced plastics composite material as the protective layer 9 of valve body 1, the anticorrosive property of whole valve body 1 can be strengthened, and when outside air temperature raises or decline, temperature transfer medium becomes the different dielectric layer of two materials by originally single metal layer, the then temperature of the valve body 1 inside situation that rapid drawdown can not occur or rise sharply, the temperature variation of valve body 1 inside is made to have a buffering course, be conducive to the stability of whole valve water conservancy diversion, valve body 1 is prevented to be damaged because of stable instantaneous variation, valve gap 3 and handwheel 5 adopt composite material, when not affecting whole valve working state, can greatly alleviate the weight of self, and handwheel 5 also can not be stuck because of getting rusty.
Be compared with the prior art: this novel throttling stop emptying valve passes through at valve body outer installment composite material protective layer 9; effectively valve body 1 is protected; improve anti-corrosion capability; and by the change of temperature transfer medium; reduce the impact of low temperature on valve body 1; valve gap 3 and handwheel 5 adopt composite material as making material, alleviate the weight of whole valve, are convenient to transhipment and install.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
