The utility model is characterized in that a floating body is arranged in the liquid storage cavity, a guide surface is arranged at the upper end inside the liquid storage cavity, and the guide surface and the floating body can form a seal to block the liquid storage cavity and the gas storage cavity. The utility model solves the technical problems in the background technology, for example, the residual gas inside the tank body can not be exhausted completely, and the data of test pressure is not accurate. The gas in the position of a safety valve seat hole can not be exhausted, an automatic exhaust structure is added in the position of the safety valve seat hole, and the gas can be exhausted completely. The spherical floating body is adopted, the guide surface is added inside the liquid storage cavity of the valve body, and the free motion of the floating body is facilitated.
Description
Technical field
The utility model relates to a kind of hydraulic testing exhaust apparatus, is specifically related to a kind of tank car tank body hydraulic testing exhaust apparatus.
Background technology
Whether the tank body of tank car all needs to detect its correlation parameter after manufacturing is finished qualified.Detection method commonly used at present is that the hydraulic testing detects, to detect be fills with water and be pressurized to certain pressure in tank body in the hydraulic testing particularly, stop pressurization then and keep certain hour, in this process, gather each parameter of tank body, parameter that obtains and reference parameter are relatively judged the situation of tank body self.Because the design feature of tank body self and the self-defect of existing hydraulic testing exhaust apparatus, cause can't the emptying tank interior residual gas, and need the gas of emptying tank interior when all explicitly calling for the hydraulic testing in some standards such as TB/T1803-2007 and the working specification, otherwise force samples is inaccurate will cause the hydraulic testing time.
Summary of the invention
The purpose of this utility model is to provide a kind of tank car tank body hydraulic testing exhaust apparatus, and its residual gas that solves tank interior in background technology can't emptying, the inaccurate technical matters of test pressure data.
Technical solution of the present utility model is:
A kind of tank car tank body hydraulic testing exhaust apparatus, the air storing cavity that comprises liquid storage cylinder and be arranged at the liquid storage cylinder upper end, described air storing cavity is communicated with by gas port with liquid storage cylinder, described liquid storage cylinder lower end is provided with the topping up hole, the upper end of described air storing cavity is provided with vent port, its special character is: a buoyancy aid is set in the described liquid storage cylinder, and described liquid storage cylinder inner upper end is provided with a spigot surface, and this spigot surface can form sealing blocking-up liquid storage cylinder and air storing cavity with buoyancy aid.
Above-mentioned air storing cavity top is provided with spherical gas port, and described air storing cavity is arranged in the bonnet, and this bonnet inside is provided with spherical, and described spherical and spherical gas port can be sealed and matched by screwing bonnet, close the air storing cavity exhaust.
Above-mentioned buoyancy aid is a ball float, and described spigot surface is spherical spigot surface, ball float and spigot surface, the structure that spherical sealing surface is formed can effectively be avoided the jammed phenomenon of buoyancy aid, and spherical sealing surface has improved sealing effectiveness simultaneously, stopped overflowing of water, reached an exhaust, the effect of not draining.
Above-mentioned liquid storage cylinder is arranged in the valve body, and the lower end of valve body is provided with screw thread, and this screw thread can be fixed in whole valve body on the tank body gland bonnet.
Above-mentioned valve body lower end face is provided with seal groove and O-ring seal, strengthens sealing effectiveness.
Above-mentioned buoyancy aid is the hollow ball shape buoyancy aid, alleviates buoyancy aid weight, helps the fast moving of buoyancy aid.Advantage of the present utility model is:
1. the gas of emergency valve seat hole site can't be discharged, and increases automatic vent structure, effectively emptying gas in the emergency valve seat hole site.
2. utilize float structure, automatic vent, not draining.
3. adopt spherical sealing surface between buoyancy aid and the valve body, strengthen sealing effectiveness.
4. employing ball float, the inner spigot surface that increases of valve body liquid storage cylinder helps moving freely of buoyancy aid.
5. buoyancy aid can adopt hollow ball, alleviates buoyancy aid weight, helps the fast moving of buoyancy aid.
6. the lockable discharge chamber of bonnet stops exhaust.
7. the valve body lower end face increases seal groove and O-ring seal, can improve the reliability that automatic exhaust device and tank body seal pad connect.
