Abstract
The utility model relates to a free float ball steam trap, aiming at solving problems of large volume, difficulty in processing and in close ground installation of prior valves. The utility model comprises a valve body with a water inlet and a water outlet, a valve cover fixed at the top of the valve body, a valve seat fixed on the valve body and float balls inside the valve body and the valve cover. The float ball center is higher than axes of the water inlet and the water outlet. The utility model has the advantages that the float ball center of the free float ball steam trap is above the axes of the water inlet and water outlet, therefore, the volume of the valve body is small, which is in favor of water delivery and close ground installation; the valve seat is directly arranged inside the water outlet, therefore, the process is simple and the process cost is low.
Description
Technical field
The utility model relates to a kind of free floating ball type Automatic steam trap Trap.
Background technique
The free floating ball type Automatic steam trap Trap is mainly used in steam heating equipment and transmission pipeline network is got rid of water of condensation, plays the effect of automatic draining resistance vapour, and it plays an important role to the raising thermal efficiency, energy saving, consumption reduction synergy.Existing free floating ball type Automatic steam trap Trap comprises and has water intake and water outlet valve body, valve gap, valve seat, and is located at the ball float in valve body and the valve gap, the wherein axis that is lower than entery and delivery port of the centre of sphere of ball float.All in valve body, valve seat then is located at the position of the nearly bottom of valve body to the spheroid of the free floating ball type Automatic steam trap Trap ball float of this structure, link to each other with water outlet by built-in channel, so the volume of valve body is bigger, is difficult for processing, and is unfavorable for the ground proximity installation; And intake-outlet position height is unfavorable for draining.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, little, the easy processing of a kind of volume is provided, helps the free floating ball type Automatic steam trap Trap of draining.
The utility model free floating ball type Automatic steam trap Trap, comprise the valve body that has water intake and water outlet, be fixed on the valve gap of valve body top and be fixed on valve seat on the valve body, and being located at valve body and the interior ball float of valve gap, the centre of sphere of described ball float is higher than the axis of water intake and water outlet.
The centre of sphere of the utility model free floating ball type Automatic steam trap Trap ball float is positioned at more than the axis of water intake and water outlet, so the volume of valve body is less, helps draining, helps ground proximity and installs; Valve seat is directly arranged in the water outlet, and technology is simple, processing cost is low.
Description of drawings
Fig. 1 is the schematic cross sectional views of the utility model free floating ball type Automatic steam trap Trap.
Embodiment
With reference to Fig. 1, the utility model free floating ball type Automatic steam trap Trap, comprise the valve body 1 that has water intake 8 and water outlet 9, be fixed on the valve gap 2 of valve body top and be fixed on valve seat 4 on the valve body 1, and be located at ball float 3 in valve body 1 and the valve gap 2: the centre of sphere of described ball float 3 is higher than the axis of water intake 8 and water outlet 9.Because the centre of sphere of ball float 3 is positioned at more than the axis of water intake 8 and water outlet 9, the volume of valve body 1 is less like this, helps draining, helps improving the thermal efficiency, helps ground proximity and installs.
As improvement of the present utility model, described valve seat 4 is tightly connected with valve body 1 and places in the water outlet 9.Compact structure like this, volume is little, and is in light weight, and technology is simple, and processing cost is low.
The water intake 8 of free floating ball type Automatic steam trap Trap can make screw thread with water outlet 9 or the system upper flange is convenient to be connected with pipeline.Like this, when water of condensation when water intake enters, ball float 3 is because buoyancy function rises, water of condensation is discharged by valve seat 4, water outlet 9.
As further improvement of the utility model, in described valve seat 4, be provided with check device 5.Like this when equipment is out of service, vapour pressure is reduced in that check device 5 plays the valve base sealing non-return energy-conservation and the effect of protection equipment under the back pressure effect in the equipment.
As further improvement of the utility model, also can be provided with drainage device 6, so that convenient discharge the when in valve body 1, dirt being arranged in the bottom of valve body 1.
As further improvement of the utility model, on valve gap, be provided with bleed valve 7.So that when valve body 1 internal air pressure is too high, exit.
Claims (5)
1, a kind of free floating ball type Automatic steam trap Trap, comprise the valve body that has water intake and water outlet, be fixed on the valve gap of valve body top and be fixed on valve seat on the valve body, and be located at valve body and the interior ball float of valve gap, it is characterized in that: the centre of sphere of described ball float is higher than the axis of water intake and water outlet.
2, float ball type steam drain valve as claimed in claim 1 is characterized in that: described valve seat and valve body are tightly connected and place in the water outlet.
3, free floating ball type Automatic steam trap Trap as claimed in claim 2 is characterized in that: be provided with check device in the described valve seat.
