Description

A kind of venting ball valve
Technical field
The utility model belongs to valve technology field, relates to a kind of ball valve, relates in particular to a kind of venting ball valve.
Background technique
Ball valve is the common control gear of a kind of energy connection or block valve in-vivo medium flow channel, therefore is widely used in various pipelines.Ball valve is made up of valve body, valve rod, handle and the spool that is arranged in the valve body usually, valve rod one end is connected with spool, and the other end is connected with handle, during use, can drive valve rod and valve core rotation by handle with sleeve, realize the purpose of connection or block valve in-vivo medium flow channel.But common ball valve only can be used in the pipeline of carrying generic media at present, when carrying high-pressure medium in the pipeline, because the highpressure in the ball valve makes ordinary ball valve have many potential safety hazards in use.
At above problem, people design a kind of Blowoff ball valve, [its publication number is: CN201232765Y], comprise valve body, handle, valve rod and ball core, the feed-water end of the sidepiece of described valve body is provided with the outlet pipe that communicates with valve inner, outlet pipe comprises tubular core body and is arranged on the interior core bar of core body that the core body sidepiece is provided with relief opening, is provided with the sealing configuration that forms sealing when both contact between core body and core bar.This Blowoff ball valve can blowdown again can exhaust, but the exhaust core is arranged on the top of feed-water end one side, with the handle homonymy, comparatively inconvenience when carrying out switch ball core and bleeding, in addition, in pipeline, carry high-pressure medium to finish, when closing ball valve,, it can't be discharged the gas of ball in-core because the exhaust core is arranged on feed-water end, the ball core is subjected to the high pressure effect for a long time, has shortened its working life.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at prior art, has proposed a kind of good airproof performance and can in time discharge the venting ball valve of ball in-core gas as required.
The purpose of this utility model can realize by following technical proposal: a kind of venting ball valve, comprise valve body, valve rod, handwheel and be arranged on the interior ball core of valve body, one end and the ball core of above-mentioned valve rod are connected, the other end stretches out valve body and handwheel is connected, it is characterized in that, described stem shaft is to a cavity is arranged, the side-walls of described cavity has the exhaust passage that makes this cavity and exterior, there is the through hole of a connection ball in-core portion and cavity on described ball core top, is equipped with the adjustable lever that can make this cavity and being connected of exhaust passage be switched on or block in the described cavity.
When the venting ball valve internal air pressure excessive, when needing exhaust, the regulating and controlling bar is connected cavity and exhaust passage, gas in the valve body inner high voltage medium rises to cavity by the through hole on ball core top, external from the exhaust passage expulsion valve of cavity side-walls, when the medium in the venting ball valve need not exhaust, the regulating and controlling bar blocked being connected of cavity and exhaust passage, and the medium in the valve body is normally carried.
In above-mentioned venting ball valve, described adjustable lever and valve rod are threaded and integral body closely cooperates.
In above-mentioned venting ball valve, described adjustable lever and cavity all are formed by connecting by several cylindrical body axially-aligned, and cylindrical radius diminishes from top to bottom one by one.The cavity and the adjustable lever of the cylindrical body linkage structure that reduces step by step from top to bottom cooperatively interact, and reduce the air ventilation in the valve rod, make that the sealing effect in the valve rod is better.
In above-mentioned venting ball valve, on the described adjustable lever near an end of bottom surface and be lower than on the position of valve stem tip and respectively be arranged with an O type circle.When venting ball valve need not exhaust, the O type circle near the bottom surface on the adjustable lever sealed up the cavity lower end, makes adjustable lever can block the passage of exhaust, and the O type circle on top can prevent that then extraneous gas from entering in the valve rod; When ball valve needed exhaust, the O type circle on top can prevent that the interior gas of valve body is from the discharge of cavity upper end.
In above-mentioned venting ball valve, described valve stem tip is connected with a nut, and described nut and handwheel are connected.Can drive valve rod and rotate, the MEDIA FLOW circulation passage in unlatching or the valve body by rotating handwheel and nut during the use venting ball valve.
In above-mentioned venting ball valve, be provided with a handwheel pad between described handwheel downside and the valve rod.
In above-mentioned venting ball valve, be provided with a seal ring between described ball core and the valve body.
In above-mentioned venting ball valve, be fixed with one outside the described exhaust passage and be communicated with exhaust passage and outside exhaust nozzle.
In above-mentioned venting ball valve, be socketed with an exhaust leather hose on the described exhaust nozzle.
Compared with prior art, this venting ball valve has the following advantages:
1, the user can be according to demand controls the whether exhaust of this venting ball valve by being arranged in adjustable lever in the valve rod, and can after conveyance conduit is closed the gas of ball in-core be discharged, and eliminates the effect of air pressure to valve body, increases the working life of ball valve.
2, cavity of this venting ball valve and adjustable lever adopt a plurality of cylindrical bodys not of uniform size to be formed by connecting, and two ends all are arranged with O type circle about it, have strengthened the sealing of this ball valve greatly.
