Summary of the invention
Technical problem to be solved by this invention just provides a kind of simple in structure; control simple safe antifreeze ball valve; anti-sealing deposits in valve body and the pipeline that is connected with the water outlet of valve body, equipment etc.; make it when low temperature, not to be subject to frost damages; the equipment corrosion phenomenon that the long-term ponding of ponding timely discharge also having significantly reduced simultaneously causes; the protection valve body reaches pipeline, the equipment that is connected with the water outlet of valve body, has also protected the sealability of valve body simultaneously.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: safe antifreeze ball valve, comprise valve body, be located at the interior ball sealer of ball sealer installation room of valve body, valve rod, handle, be provided with passage in the described ball sealer, the inner ball sealer that connects of described valve rod, the valve rod outer end is stretched out valve body and is connected with handle, the valve body two ends are water intake and water outlet, it is characterized in that: described body wall is provided with the weep hole that is communicated with described ball sealer installation room, also be provided with the spilled water hole with channel connection on the described ball sealer wall body, at the described water outlet of valve closing state, spilled water hole, passage, the ball sealer installation room, weep hole is communicated with successively.
As preferably, the pipeline in the described valve body between water intake and water outlet is a rectilinear duct, and described weep hole tilts and described rectilinear duct axially is 70 ° to the water intake direction.This kind design is applicable to water outlet installation environment up, is beneficial to draining.
Preferably, described weep hole is located at the bottom of body wall.This kind design is applicable to the horizontal installation environment of water outlet, is beneficial to draining.
Preferred a kind of structure, described spilled water hole and channel vertical setting.
Improved, be connected with hose coupling on the described weep hole.Hose coupling adopts standard interface, can be connected with Φ 6cm hole flexible pipe, and ponding is entered sewer.
Improved, described hose coupling is threaded with weep hole, also is provided with a bowl seal circle between hose coupling and weep hole, and described bowl seal circle adopts PTFE Te Fulong or NBR nitrile rubber material.Material wear-resistant self lubricity height.
Preferably, inboard socket one valve gap of described water outlet is provided with a valve seat between described valve gap medial extremity and ball sealer, also is provided with valve seat between ball sealer and water intake madial wall.When ball sealer be in close or opening process in any position the time, ball sealer and valve seat and seal ring can be formed a cover sealing pair, can guarantee to disconnect between the weep hole of equipment and side, have prevented the wasting phenomena of water.
The present invention is owing to adopted technique scheme; in off position down; ponding in the equipment that water outlet connected is discharged through the passage of ball sealer spilled water hole and weep hole composition; reach automatically purpose, thereby played when the cold and hot variation of temperature protective action equipment with the unnecessary ponding discharge in valve body and the pipeline that is connected with the water outlet of valve body, the equipment.This product specification compactness, installing space be little, it is simple and convenient to install and change, flexible operation.
