Abstract
The utility model relates to a manual high-temperature asphalt valve which comprises a vertical cylindrical valve body, wherein a fluid inlet and a fluid outlet are arranged at the upper part and the lower part of the side wall of the cylinder of the valve body, a valve shaft extending out of the valve body is arranged in the valve body, a screw rod type manual driving device is connected on the valve shaft, a circular ring-shaped valve body sealing ring with a rectangular section is arranged between the fluid inlet and the fluid outlet in the valve body, and a round platform-shaped valve core matched with the valve body sealing ring is arranged on the valve shaft in the valve body. The round platform surface with the round platform-shaped valve core and the inner circumference of the lower circular ring port of the valve body sealing ring constitute a sealing pair. During the closing process, the circular upper bottom surface of the round platform surface of the valve core is inserted into the circular ring-shaped valve body sealing ring from the lower circular ring port of the circular ring-shaped valve body sealing ring, and the lower circular ring port pushes against the round platform surface of the valve core like a cutting edge for cutting off asphalt flow so as to be conductive to cutting off the asphalt flow with greater viscosity; and a jacket which can enable a high-temperature medium to pass is arranged outside the valve body, thereby preventing the viscosity of asphalt from increasing due to temperature reduction and being conductive to enabling the asphalt with the greater viscosity to flow by. The manual high-temperature asphalt valve is suitable for being used in pipelines for conveying the asphalt with the greater viscosity at high temperature.
Description
Technical field
The utility model relates to a kind of fluid-transporting tubing valve, particularly a kind of valve that flows and stop of controlling pitch in the pipeline of carrying hard pitch.
Background technique
Valve is used to control the mobile of fluid and stop in fluid-transporting tubing.Valve has valve body, there is the fluid inlet/outlet both sides of valve body, the valve shaft that stretches out valve body is arranged in the valve body, be connected with drive unit on the valve shaft, drive unit has the screw type manual driving device, and fluid pressure drive device and pneumatic actuating device are also arranged, and between the fluid inlet/outlet in the valve body valve seal ring is arranged, on the valve shaft in the valve body spool that matches with the valve seal ring is arranged, between spool and the valve seal ring sealing pair is arranged.
Pitch is solid when normal temperature, be the bigger fluid of viscosity under higher temperature, when pitch became fluid state under high temperature, temperature was very big to the viscosity influence of pitch, the viscosity of pitch was lower when temperature was high, and temperature has the viscosity of pitch when reducing to improve bigger slightly.In industrial production, in order to allow pitch can use line transportation, be heated to higher temperature to pitch becomes fluid, with the line transportation of insulation.In the asphalt delivery pipeline, the valve that have the control hard pitch in pipeline, to flow and stop.In the prior art, in the pipeline of carrying hard pitch, do not control the special valve that flows and stop of pitch, in the pipeline of carrying hard pitch is to select General valve of the prior art for use, General valve has ball valve, butterfly valve, gate valve, stopcock, stop valve etc., these valves are applicable in the pipeline of the less flowing medium of transport viscosity at normal temperatures and use, are not suitable in the pitch pipeline that at high temperature transport viscosity is bigger and use.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of manual hard pitch valve that uses in the pitch pipeline that at high temperature transport viscosity is bigger that is applicable to.
The utility model is realized with the following method.
Manually the hard pitch valve has valve body, the both sides of valve body have fluid to advance, outlet, the valve shaft that stretches out valve body is arranged in the valve body, be connected with the screw type manual driving device on the valve shaft, fluid in the valve body advances, the valve seal ring is arranged between the outlet, on the valve shaft in the valve body spool that matches with the valve seal ring is arranged, valve body is vertical cylinder valve, fluid advances, outlet is on the valve body cylinder side wall, the bottom, valve shaft stretches out from the top of valve body, the axis of valve shaft and the axis of cylinder valve are on same straight line, there is chuck in the valve body outside, chuck has chuck to advance, outlet, the valve seal ring is to advance at the valve body inner fluid, rectangular cross-section annulus between the outlet, the axis of annular valve seal ring and the axis of cylinder valve are on same straight line, and spool is the frustoconic shape spool, and the inner circumference of annulus mouth is formed sealing pair under the round table surface of frustoconic shape spool and the valve seal ring.
Sealing pair between valve seal ring of the present utility model and the frustoconic shape spool is the sealing pair that the inner circumference of annulus mouth under the round table surface of frustoconic shape spool and the valve seal ring is formed.The utility model is in closing closed procedure, the circular upper bottom surface of spool round table surface annulus mouth under the annular valve seal ring inserts in the annular valve seal ring, at last, the spool round table surface is against under the annular valve seal ring on the annulus mouth, when the spool round table surface is against under the annular valve seal ring on the annulus mouth, following annulus mouth is against on the spool round table surface as cutting edge, cut-out pitch stream, help by the bigger pitch stream of viscosity, realize linear sealing between frustoconic shape spool and valve seal ring, the sealing sealing is reliable; Valve body of the present utility model has chuck outward, and chuck has the chuck inlet/outlet, during use, can be connected with high temperature media in the chuck, the temperature that keeps pitch in the utility model valve body prevents that pitch Yin Wendu from reducing and the viscosity increase, helps the bigger pitch of viscosity and flow through the utility model.The utility model is applicable in the pitch pipeline that at high temperature transport viscosity is bigger and uses.
Below in conjunction with accompanying drawing, the utility model is further described.
