Abstract
The invention relates to an improved stop valve which comprises a valve body. The valve body is provided with a transition cavity, and the two sides of the transition cavity are provided with an inlet channel and an outlet channel respectively. According to the transition cavity, the inlet channel and the outlet channel are communicated. The bottom end of the transition cavity is provided with a drainage channel, the drainage channel is of a cylindrical structure, and the drainage channel is parallel to the outlet channel and is arranged opposite to the outlet channel. A fixing plug is arranged in the drainage channel. The structure is simple, impurities in fluid flowing through the stop valve can be effectively filtered out, safety and reliability are achieved, meanwhile, the service life is improved, and cost is saved.
Description
Technical field
The present invention relates to a kind of stop valve.
Background technique
The open-shut device of stop valve is the flap of stopper, sealing surface is plane or the conical surface, flap is along the center line moving linearly of valve seat, the forms of motion of valve rod, also there is lifting rotation rod-type, stop valve refers to the valve that closure member (flap) moves along valve seat center line, according to this mobile form of flap, the variation of valve seat port is and flap stroke relation in direct ratio, because valve rod unlatching or the shutoff stroke of such valve are relatively short, and there is very cutting function reliably, again due to the variation of valve seat port and the stroke of flap relation in direct ratio, be very suitable for the adjusting to flow, therefore, such stop valve valve that dams is suitable as cut-out or adjusting and throttling and uses very much.
But stop valve is in regulating the process of liquid, the impurity carrying in liquid can be deposited in valve bottom, valve is caused to the irreversible damages such as corrosion, finally causes valve to damage, and has reduced working life.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of stop valve of improvement, simple in structure, can effectively filter out the impurity in liquid in the stop valve of flowing through, safe and reliable, has increased working life simultaneously, has saved cost.
For solving the problems of the technologies described above, technological scheme of the present invention is:
A kind of stop valve of improvement, comprise valve body, described valve body is provided with adapter cavity, described adapter cavity both sides are respectively equipped with inlet passage and outlet passage, described adapter cavity, inlet passage is connected with outlet passage, wherein, described adapter cavity bottom is provided with drainage channel, described drainage channel is cylindrical structural, described drainage channel parallels with outlet passage, and be oppositely arranged with outlet passage, in described drainage channel, be provided with fixed plug, described fixed plug comprises fixed plug main body, fixed plug end cap and filter element, described fixed plug main body is cylindrical structural, fixed plug main body and drainage channel interference fit, described fixed plug end cap is cylindrical structural, the diameter of fixed plug end cap is greater than the diameter of fixed plug main body, described fixed plug end cap equates with the angle b of vertical direction with angle a and drainage channel between fixed plug main body, described fixed plug end cap and fixed plug main body are integral type structure, described filter element comprises filter frame and filter screen, described filter screen is fixed on the below of described filter frame, described filter frame is fixed in described fixed plug main body, described filter frame be take carbon fiber as material.
The stop valve of above-mentioned a kind of improvement, wherein, described outlet passage inner side is provided with one deck filter membrane.
Beneficial effect of the present invention is:
When the present invention uses, fixed plug is filled in drainage channel, now, the filter frame of being made by carbon fiber elastic material and filter screen level are laid on adapter cavity bottom, open stop valve, liquid is circulated, now, the impurity carrying in liquid is just precipitated in the filter screen of the nanofiber level bottom adapter cavity, after when valve is used one section, throttle down, extract fixed plug, the impurity being deposited in filter screen can be taken out of with fixed plug, simultaneously, also liquid residual in valve can be emitted to valve in the lump, avoided impurity or liquid to corrode valve inwall, affect its sealing, thereby increased the working life of stop valve.
Fixed plug is provided with fixed plug end cap, can realize easily and fast putting into and taking out of fixed plug, has saved manpower and materials, has saved resource.
State outlet passage inner side and be provided with one deck filter membrane, played the effect of filtering, can further avoid liquid that magazine is taken out of, then clear out by filter screen.
