Valve body, sealing nut, airtight and watertight padding, gland and valve rod, wherein, valve body is circle in vertical direction
Column casing structure, and the projection of horizontal cylindrical structure is formed in cylindrical drum side wall, valve body is formed vertical side
To and horizontal direction connect passage；Valve rod is arranged in the passage of valve body vertical direction upper end, valve rod lower end
The screw thread of the helicitic texture of cylindrical body outer wall and valve body upper end at horizontal through hole matches, and valve rod most under
The part pyramid like configuration at end can realize linear sealing with valve body lower portion passway；Valve rod upper end cylindrical body outer wall and valve
Annular space between internal wall is fixed filled with airtight and watertight padding and using gland.
Screw thread of the described valve body upper end at horizontal through hole is trapezoidal thread.
Described gland upper end is by the nut through valve rod upper end and the screw thread knot of valve body external wall of upper portion
Structure, gland and airtight and watertight padding are fixed.
Described airtight and watertight padding is polytetrafluoroethylene (PTFE).
Screw thread between described valve body and valve rod has a self-locking performance, and by the size of pitch come control valve
Aperture.
The cylindrical end face of described body wall compresses polytetrafluoroethylene sealing gasket and realizes out by gland nut
Mouth sealing.
Described valve body lower end uses NPT3/4 to seal pipe screw thread and tining treatment is carried out to it to ensure import
Sealing.
Described valve body uses copper material；The Ni-based conjunction of high rigidity that described valve rod is processed using flow harden
Gold is made.
Remarkable result of the invention is：A kind of hex filler special formula right-angle valve of the present invention,
Possess the ability for bearing elevated pressures load, be provided simultaneously with passage leak rate and valve body leak rate requirement higher.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail to the present invention.
As shown in figure 1, a kind of hex filler special formula right-angle valve, including valve body 1, sealing nut 2,
Airtight and watertight padding 3, gland 4 and valve rod 5, wherein, the generally cylindrical structure of valve body 1, and in side
The cylinder of the horizontal direction of the projection of wall formation cylindrical structure, the in the vertical direction of valve body 1 and side wall
In be provided with passage, make to form the right angle channel of connection between the bottom of valve body 1 and side wall cylinder；Valve body 1
It is shoulder hole structure in top, and trapezoidal thread structure is being formed at the position of sidewall horizontal through hole；Valve
Bar 5 is cylindricity requirement cylindrical-shaped structure higher, and cylinder extracorporeal thread and the valve body 1 of its lower end are close to water
The trapezoidal thread of flat through hole matches, and the annular space between the upper end side wall of valve rod 5 and the inwall of valve body 1 leads to
Cross airtight and watertight padding 3 to be filled, and compressed airtight and watertight padding 3 using gland 4, and utilize through valve
The nut of the upper end of bar 5 and the helicitic texture of the external wall of upper portion of valve body 1, by gland 4 and airtight and watertight padding 3
It is fixed；The bottom of valve rod 5 is part pyramid like configuration, and itself and the lower passage cause for gossip of valve body 1 show linear sealing,
And passing through the aperture of the pitch controlled valve door of valve rod 5 and valve body 1, its screw thread has self-locking performance；Sealing is filled out
Material 3 is polytetrafluoroethylene (PTFE)；The cylindrical end face of the side wall of valve body 1 compresses polytetrafluoroethylene (PTFE) by gland nut 6
Sealing gasket realizes exit seal；The lower end of valve body 1 seals pipe screw thread and carries out tining treatment to it using NPT3/4
