Abstract
A novel high-temperature and high-pressure stop valve comprises a valve body (1), a valve cover (2), a valve core (3) and a valve rod (4). A valve chamber (5) is arranged inside the valve body (1) which is equipped with a sampling water inlet (6) and a sampling water outlet (7). The novel high-temperature and high-pressure stop valve is characterized in that the main body of the valve body (1) is a rectangular body; the sampling water inlet (6) and the sampling water outlet (7) are disposed on two transverse planes of two sides of the valve body (1) along the length; heat dissipation portions (9) symmetrically extend from two sides of the valve body (1) along the width of the rectangular body; and the heat dissipation portions (9) are equipped with multiple heat dissipation through holes (10). Through adoption of the heat dissipation portions and the heat dissipation through holes disposed in the heat dissipation portions, the heat dissipation capability of the valve body is greatly improved. Actual applications show that the above design enables the temperature of the valve body, the valve rod and other parts in the valve to be reduced by 20-30 DEG C, such that thermal expansion of the parts is minimized, the valve core is not liable to be blocked dead, and the valve is smooth to open and close.
Description
Technical field
The utility model relates to valve field, is specifically related to the high temperature and high pressure cut-off valve on water vapor sampling equipment in thermal power plant.
Background technique
Thermal power plant must configure water and steam sampling equipment, regularly detects the quality of steam operation with water and steam sampling equipment, is the important step of guaranteeing power plant safety reliable operation.Water and steam sampling equipment is to be mainly low-temp low-pressure sample water by the step-down of High Temperature High Pressure sample water for cooling, so that by the regulation requirement in power industry standard, detects the relevant parameters of each sample point by chemical instruments.Once door on water and steam sampling equipment adopts high temperature and high pressure cut-off valve, in the time that the High Temperature High Pressure sample water attracting from boiler is delivered to water and steam sampling equipment, and the high temperature and high pressure cut-off valve of first flowing through, and then flow to other system parts.
Stop valve is a kind of valve that utilizes spool to move fluid medium channel in opening and closing pipeline along valve body center line, this valve is mainly made up of valve body, valve gap, spool and valve rod, valve body is provided with valve pocket, spool is arranged in valve pocket, valve gap is connected with valve body port, valve rod stretches into valve pocket and acts on spool in set through hole from valve gap, forms opening and closing two states thereby spool is coordinated with the passage on valve body.
Due on water and steam sampling equipment, high temperature and high pressure cut-off valve is once door, the water bearing, the maximum temperature of vapour are generally 540 ℃ of left and right, pressure is in 20MPa left and right, because extreme temperatures, each parts expanded by heating in valve, matching gap reduces, often cause the stuck of high-pressure stop valve core, to such an extent as to valve switch difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of new type high temperature high-pressure stop valve, easily stuck to solve existing high-pressure stop valve core, the problem of valve switch difficulty.
For achieving the above object, the technical solution adopted in the utility model is: a kind of new type high temperature high-pressure stop valve, comprise valve body, valve gap, spool and valve rod, and in valve body, establish valve pocket, on valve body, establish sample water inlet and sample water outlet; Sample water inlet communicates with valve pocket through passage, and sample water outlet also communicates with valve pocket through passage; The main body of described valve body is a cuboid, an interface joining with valve gap is extended towards thickness direction in the middle part of the length direction of this cuboid, described valve pocket is arranged with and forms towards cuboid inside by jointing, and described sample water inlet and sample water outlet are arranged on the two ends end face of length direction of valve body; The bilateral symmetry of described valve body on the width direction of cuboid extended radiating part, and this radiating part is provided with multiple heat radiation through holes.
Related content in technique scheme is explained as follows:
1,, in such scheme, described heat radiation through hole is arranged in a row along the length direction of cuboid.
2, in such scheme, described " interface joining with valve gap is extended towards thickness direction in the middle part of the length direction of this cuboid " from and " bilateral symmetry of described valve body on the width direction of cuboid extended radiating part " described in length direction, thickness direction and width direction be corresponding, be equal to tri-axles of X, Y, Z in system of coordinates, length direction is the trend of longest edge in cuboid, and width direction and thickness direction be with length direction perpendicular another two axially, width direction and thickness direction can exchange definition.
Owing to having adopted technique scheme, the utlity model has following advantage:
The utility model is by arranging radiating part, on radiating part, offer heat radiation through hole, significantly increase the heat dissipation potential of valve body, border probationary certificate factually, this design can make the part temperatures decline 20-30 ℃ such as valve inner valve body and valve rod, thereby reduced the thermal expansion amount of parts, spool has been difficult for stuck, valve switch is smooth and easy.And the utility model does not increase the parts such as radiator in addition, has just increased slightly volume in the time that valve body designs, and has increased this position of radiating part, then holes on radiating part, easy to make, cost is low.
