Abstract
The utility model discloses a cylinder floating ball drain valve, relating to a mechanical type drain valve, in particular to a floating ball drain valve which adopts a zero fulcrum omni-lever structure, semi-cylinder sealing and an oblong drain hole. The floating ball drain valve is provided with a valve body, a middle part valve body, a valve bonnet, a valve base, a cylinder valve core, a floating ball, a lever and a Y type exhaust device. The middle part valve body is positioned on the valve body, and the front and the back of the middle part valve body are respectively provided a water inlet and a water outlet. The valve bonnet is positioned on the middle part valve body. The cylinder valve core is provided on the valve base. The floating ball is provided in the valve cavity of the valve body, and the floating ball is connected with one end of the lever, and the other end of the lever is pin connected with the cylinder valve core. The valve hole is in the shape of oblong. The exhaust device is provided between the valve bonnet and the middle part valve body. The floatage is high and the displacement is high for adopting the zero fulcrum omni-lever structure. The cylinder sealing sliding type motion mode is adopted, thus the floating ball drain valve does not have impinging and abrasion when thefloating ball drain valve is opened and closed, the sealing performance is good, the service life is long, and the floating ball drain valve does not need maintenance. The oblong valve hole is adopted, thus the floating ball drain valve does not have vortex when discharging, and steam does not have loss. The operating temperature and the pressure variation are not be influenced, the water discharging process is automatically controlled according to the water level proportion.
Description
Technical field
The utility model relates to a kind of mechanical-type drain valve, especially a kind of Ball float steam trap that adopts zero branch to put full lever construction, semicylinder sealing, rectangular weep hole.
Background technique
The mechanical-type drain valve is a kind of widely used drain valve because structure is unreasonable, therefore exist action sensitivity low, open deficiency such as bump is arranged when valve closes valve, sealing is poor, leakage phenomenon is arranged during work, working life is short.
Summary of the invention
The utility model aims to provide a kind of action sensitivity height, do not open valve close do not have leakages when valve has bump, good airproof performance, work, cylinder Ball float steam trap little, long service life weares and teares.The utility model adopts zero branch to put full lever construction, the sliding type manner of execution of cylinder sealing and the technological scheme of rectangular weep hole for this reason.
The utility model is provided with valve body, the middle part valve body, bonnet, valve seat, the cylinder spool, ball float, lever and Y type venting gas appliance, the middle valve body is positioned on the valve body and with valve body and is connected, establish intake-outlet respectively before and after the valve body of middle part, bonnet is positioned on the valve body of middle part and with the middle part valve body and is connected, the cylinder spool is located on the valve seat, ball float is located in the valve pocket of valve body with water level automatic lifting in the chamber, ball float connects an end of lever, the lever the other end and cylinder spool pin joint, drive the cylinder spool and open and close valve opening, valve opening is rectangle, and Y type venting gas appliance is located between bonnet and the middle part valve body.
Owing to adopt zero branch to put full lever construction, so buoyancy is big, discharge capacity is big; Owing to adopt the sliding type manner of execution of cylinder sealing, rational in infrastructure, therefore when driving valve and closing valve, there is not bump, almost there are not wearing and tearing during work, 1 movable part is only arranged, good airproof performance not only, working life is very permanent, and need not basically to maintain; Owing to adopt the rectangular valve opening, do not have eddy current, steam free of losses when therefore discharging.Simultaneously, operating temperature of the present utility model, variation in pressure are unaffected, control drainage procedure automatically according to the water level ratio.Its superior function can both be given full play under the bad working environments of saturated vapour, the high superheated vapor of low pressure, little load.

Fig. 2 is the utility model embodiment's a plan structure schematic representation.
Embodiment
As Fig. 1, shown in 2, the utility model is provided with valve body 1, middle part valve body 2, bonnet 3, valve seat 4, cylinder spool 5, ball float 6, lever 7 and Y type venting gas appliance 8, middle part valve body 2 is positioned on the valve body 1 and with valve body and is connected, valve body 2 front and back, middle part are established intake-outlet 9 respectively, 10, bonnet 3 is positioned on the valve body 2 of middle part and with the middle part valve body and is connected, cylinder spool 5 is located on the valve seat 4, ball float 6 is located in the valve pocket 11 of valve body 1 with water level automatic lifting in the chamber, ball float 6 connects an end of lever 7, and lever 7 the other ends and cylinder spool 5 pin joints drive the cylinder spool and open and close valve opening, valve opening is rectangle, and Y type venting gas appliance 8 is located between bonnet 3 and the middle part valve body 2.
During work, according to the density difference of water of condensation and steam, automatic lifting drives cylinder spool 5 by lever 7 and opens or close valve orifice ball float 6 with the variation of water level in the valve pocket 11.Because water intake 9 below higher water level, forms water seal, water, vapour natural separation, no steam leakage.Can select material, inside nominal diameter, boundary dimension such as valve body according to Maximum operating pressure, Maximum operating temperature, water of condensation discharge capacity, pressure reduction and the Placement (screw thread or flange etc.) of gas utilization unit.
Claims (1)
1, the cylinder Ball float steam trap, it is characterized in that being provided with valve body, the middle part valve body, bonnet, valve seat, the cylinder spool, ball float, lever and Y type venting gas appliance, the middle valve body is positioned on the valve body and with valve body and is connected, establish intake-outlet respectively before and after the valve body of middle part, bonnet is positioned on the valve body of middle part and with the middle part valve body and is connected, the cylinder spool is located on the valve seat, ball float is located in the valve pocket of valve body with water level automatic lifting in the chamber, ball float connects an end of lever, the lever the other end and cylinder spool pin joint also drive cylinder spool open and close valve opening, valve opening is rectangle, and Y type venting gas appliance is located between bonnet and the middle part valve body.
