Abstract
The invention discloses a pressure measurable ball valve for tests and belongs to the field of valves. The pressure measurable ball valve for tests comprises a valve rod and a valve seat; the surface of a ball is provided with an allyl-boron-phenolic-titanium nano coating arranged in a valve body; the water incoming end of the valve body is provided with a screwed blind hole, an annular protecting wall protruded downwardly is arranged below the screwed blind hole, and the screwed blind hole is connected to a corrugated pipe pressure gauge; the pressure sensing corrugated pipe of the pressure gauge is arranged in a pressure gauge joint and extends into the annular protecting wall; the pressure gauge joint and the annular protecting wall are in fit clearance. By the aid of the pressure measurable ball valve, the pressure parameters of the ball valve can be measured more accurately.
Description
Technical field
The present invention relates to invention field, specifically a kind of experiment pressure can survey ball valve.
Background technique
Ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.Be provided with spheroid in ball valve, realize opening or closing the function of medium channel mainly through spinning ball, then cut-outs can be played, distribute and the effect in change media flow direction.
When testing, more accurate to every data demand, still there is certain error at the external pressure gauges measure pressure of conduit pipe, accurately can not reflect the pressure in ball valve, there is certain experimental error.
Summary of the invention the present invention aims to provide a kind of experiment pressure can survey ball valve, is intended to solve the problem.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of experiment pressure can survey ball valve, comprises valve rod, valve seat, it is characterized in that: spherome surface is provided with boron phenolic aldehyde-titanium nano coating, is arranged in valve body; The feed-water end of described valve body has tapped blind hole, and tapped blind hole has the protection ring wall to lower convexity, and tapped blind hole is connected with bellows pressure gauge; Described manometric pressure sensitive bellows is arranged in GAUGE CONNECTOR, stretches in protection ring wall; Described GAUGE CONNECTOR and protection ring wall interference fit.
Described protection ring wall has the groove placing sealing O shape circle.
Have the screw thread of tapped blind hole adaptation in the middle part of described GAUGE CONNECTOR, major diameter of thread is greater than the diameter of GAUGE CONNECTOR.
Beneficial effect of the present invention is:
One, scribble boron phenolic aldehyde-titanium nano coating at spherome surface, boron phenolic aldehyde-titanium nano coating is a kind of heat resisting and pressure resisting resistant material, effectively avoids pressure excessive in an experiment to cause spheroid to damage, breaking test integrity.
Two, directly stretch in the fluid passage of ball valve by manometric pressure sensitive bellows, the data of measurement are more accurate.
Three, in valve body, be provided with the protection ring wall to lower convexity, the protection ring wall flowing medium avoided in fluid passage directly acts on manometric, avoids excessive scouring force damage pressure gauge.
Four, GAUGE CONNECTOR and protection ring wall interference fit, and sealing O shape circle is set on protection ring wall, avoid medium to reveal from the gap of Bonding pressure table.
Accompanying drawing explanation
Fig. 1 is that experiment pressure provided by the invention can survey ball-valve structure schematic diagram.
Mark in figure: 1 be valve body, 2 be pressure gauge, 3 be protection ring wall, 4 be spheroid, 6 be valve seat, 7 be valve rod, 8 be screw thread, 9 be GAUGE CONNECTOR for sealing O shape circle, 5.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described.
As shown in Figure 1, a kind of experiment pressure can survey ball valve, comprises valve rod 7, valve seat 6, it is characterized in that: spheroid 5 surface is provided with boron phenolic aldehyde-titanium nano coating, is arranged in valve body 1; The feed-water end of described valve body 1 has tapped blind hole, and tapped blind hole has the protection ring wall 3 to lower convexity, and tapped blind hole is connected with bellows pressure gauge 2; The pressure sensitive bellows of described pressure gauge 2 to be arranged in GAUGE CONNECTOR 9, stretches in protection ring wall 3; Described GAUGE CONNECTOR 9 and protection ring wall 3 interference fit.On described protection ring wall, 3 have the groove placing sealing O shape circle 4.Have the screw thread 8 of tapped blind hole adaptation in the middle part of described GAUGE CONNECTOR 9, screw thread 8 external diameter is greater than the diameter of GAUGE CONNECTOR 9.
In use; with grease lubrication sealing O shape circle 4; tighten after again the screw thread 8 in GAUGE CONNECTOR 9 being wound around raw meal belt, prevent flowing medium from the gap leakage between protection ring wall 3 and GAUGE CONNECTOR 9, need when mounted to ensure that the induction bellows of pressure gauge 2 stretches in protection ring wall 3.Flowing medium directly impact protection ring wall 3 on, then walk around protection ring wall 3, from its under shed enter protection ring wall 3, remake for bellows lower end, compress bellows.Can not bellows be directly acted on, avoid bellows breakage under the washing away of flowing medium.Scribble boron phenolic aldehyde-titanium nano coating on the surface of spheroid 5, boron phenolic aldehyde-titanium nano coating is a kind of heat resisting and pressure resisting resistant material, effectively avoids pressure excessive in an experiment to cause spheroid to damage, breaking test integrity.Adopt the present invention, more can accurately measure the pressure parameter in ball valve.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
