Abstract
The utility model discloses a water drain valve which comprises a tubular valve body and a rod-shaped valve spool. The outer end of the rod-shaped valve spool is connected with a switch, the tubular valve body comprises a valve body portion and a connecting portion which are integrated, a hexagonal columnar structure is arranged on the periphery of the valve body portion, a water outlet pipe is arranged on the hexagonal columnar structure, a cylindrical structure is arranged on the periphery of the connecting portion, and a sealing ring, a flat gasket and a locking nut sequentially sleeve the periphery of the cylindrical structure. The water outlet pipe is directly and integrally arranged on the valve body portion to directly achieve the technical purposes of draining water and reducing pressure and manufacturing cost, a water inlet pipe is closely connected onto the connecting portion to prevent water leakage by the aid of the sealing ring, the flat gasket and the locking nut on the connecting portion, and the airtight effect of connection of the water drain valve is improved.
Description
Technical field
The utility model relates to a kind of pipeline valve body, specifically a kind of discharging valve.
Background technique
Valve is of a great variety at present, mainly contains the large classifications such as ball valve, safety valve, air valve.In the large class of existing safety valve, there is a kind of discharging valve, mainly prevent the excessive technical problem causing of water body pressure in pipeline.Because discharging valve is huge for the demand in market, each tiny improvement all can bring great market interest, how to simplify, reduce the research object that manufacture cost is those skilled in the art always.
Chinese utility model patent patent No. ZL201120395750.5 discloses a kind of discharging valve, comprises valve body and spool; Described valve body is provided with spool bore, inlet tube and outer pipe, and inlet tube and outer pipe are communicated with spool bore respectively; Described discharging valve also comprises elastic component and fixed block; Described spool comprises core section, epimere and hypomere; Core section be shaped as frustum type, core section is provided with the through hole for being communicated with inlet tube and outer pipe, epimere is connected with the large end of core section, hypomere is connected with the small end of core section; Described spool bore be shaped as the frustum type mating with core section, the end diameter of spool bore is less than the end diameter of core section; Described hypomere is through spool bore and elastic component, and fixed block is pushed down elastic component and is connected with hypomere.This kind of relative complex structure of discharging valve, and be unfavorable for reducing manufacture cost, there is no technical clarification or the solution of this respect yet.
Summary of the invention
The utility model provides a kind of simple in structure, low cost of manufacture, good sealing effect to prevent the discharging valve leaking.
A kind of discharging valve, comprise tubular valve body and shaft-like spool, shaft-like spool outer end is connected with switch, described tubular valve body comprises valve body part and the attachment portion of one, valve body point periphery is hexagonal cylindrical structure, hexagonal cylindrical structure is provided with outlet pipe, and attachment portion periphery is round column structure, and round column structure periphery is overlapped successively seal ring, flat gasket and locking nut.This kind of discharging valve is by being located at direct outlet pipe one the technical purpose that directly reaches the decompression that discharges water on valve body, and the seal ring of attachment portion, flat gasket and locking nut triple arrange the intake pipe of water inlet to be connected to closely on attachment portion prevent from leaking, improve discharging valve connect obturation effect.
A described valve body point outer end is provided with the interior threaded hole shaft-like spool that is threaded, and realizes the switching of discharging valve by the shaft-like spool of screw thread rotation, further simplifies the structure, and reduces manufacture cost.
Described outer end, attachment portion is provided with extension diameter section, extension diameter section periphery is provided with outside thread, connect the endoporus of outside intake pipe by outside thread, and the locking nut that the periphery of intake pipe has been threaded on discharging valve connected element, the inside and outside dual of having realized intake pipe connects, and has greatly improved the connection seal of discharging valve.
The inscribed circle diameter of described hexagonal cylindrical structure is greater than the diameter of round column structure, and forms step surface in joint, and step surface inner side is connected and is placed on the seal ring of shaft-like spool end.The inscribed circle diameter of hexagonal cylindrical structure is greater than the diameter of round column structure, and form step surface this kind of structure extension diameter section in conjunction with outer end, attachment portion in joint, seal ring, flat gasket and locking nut are limited between step surface and extension diameter section and prevent that seal ring, flat gasket and locking nut from coming off, losing, reduce the accidental damage of discharging valve in installation process.Step surface inner side be connected the seal ring that is placed on shaft-like spool end improve shaft-like spool for discharging valve the airtight performance under in off position.
Described shaft-like spool end is provided with undergauge section, and the be connected center hole of attachment portion of tubular valve body of undergauge section, to increase the coaxality between shaft-like spool and tubular valve body.
The utility model is by being located at direct outlet pipe one the technical purpose that directly reaches the decompression reduction manufacture cost that discharges water on valve body, and the seal ring of attachment portion, flat gasket and locking nut triple arrange the intake pipe of water inlet to be connected to closely on attachment portion prevent from leaking, improve discharging valve connect obturation effect.
