Link, the locking sleeve side appearance wall are provided with seal closure.
As further describing for above-mentioned technical proposal：
There are two the pressure valve is installed altogether, and two pressure valves are symmetrical about the vertical center line of valve body.
As further describing for above-mentioned technical proposal：
The cross section of the spool is trapezoidal symmetrical structure, and the upper end diameter of spool is more than lower end diameter 4cm.
As further describing for above-mentioned technical proposal：
To be threadedly coupled between the outer ring valve rod and inner ring valve rod, and the outer diameter of the internal diameter of outer ring valve rod and inner ring valve rod
It is equal in magnitude.
As further describing for above-mentioned technical proposal：
The cross section of the seal closure is semicircular arc structure.
In the utility model, first by the seal closure of setting, the junction of positioning pin and locking sleeve can be played
The effect of sealing and dustproof avoids introduced contaminants from entering the phenomenon that the two junction pollutes, consequently facilitating user of service carries out
It operates with, secondly by the pressing offset plate of setting, can be pressed when spool declines and valve inner is sealed by squeezing
Connection gap of the rubber alloy plate between spool and valve body inner surface wall is sealed filling, so as to ensure that the leakproofness of junction,
The phenomenon that flow leaks will not occur, on the other hand the static balancing valve overall construction design advantages of simple, connect between parts
Stabilization is connect, simple operation is flexible, stabilization safe to use, has stronger practicability.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.
With reference to Fig. 1-3, a kind of HVAC static balancing valve, including valve body 2,2 inner surface wall of valve body is provided with antirust coat 3, valve body 2
Upper surface both sides are provided with pressure valve 1, and 2 upper surface of valve body is fixed with display 12, and 12 outer surface of display is fixed with locking
Casing 11, locking sleeve 11 are internally provided with inner ring valve rod 7, and 7 top of inner ring valve rod is connected by retaining sleeve 9 and regulation handle 10
It connects, and 10 both sides of regulation handle are welded with anti-drop block 8,7 surface of inner ring valve rod is socketed with outer ring valve rod 6, and 6 bottom of outer ring valve rod
Spool 5 is provided with, 5 lower surface of spool is provided with elastomeric pad 4, and 5 both sides of spool, which are provided with, presses offset plate 13, in locking sleeve 11
Portion side is provided with positioning pin 16, and 16 outer surface of positioning pin is provided with link 15, and 11 side appearance wall of locking sleeve is provided with
Seal closure 14.
Pressure valve 1 is altogether there are two installations, and two pressure valves 1 are symmetrical about the vertical center line of valve body 2, spool 5 it is transversal
Face is trapezoidal symmetrical structure, and the upper end diameter of spool 5 is more than lower end diameter 4cm, is between outer ring valve rod 6 and inner ring valve rod 7
It is threadedly coupled, and the internal diameter of outer ring valve rod 6 and the outer diameter of inner ring valve rod 7 are equal in magnitude, the cross section of seal closure 14 is semi arch
Shape structure.
In spool 5 and during 2 inner surface wall contact squeeze of valve body, pressing offset plate 13 by the extruding force of both sides by compressive deformation,
And then filling is sealed to 5 junction of spool, the phenomenon that avoiding leaking.
Operation principle：In use, valve body 2 is mounted on to the job site of heating and ventilating equipment, when rotating clockwise regulation handle
When 10, regulation handle 10 drives inner ring valve rod 7 to be rotated in 6 internal thread of outer ring valve rod, and inner ring valve rod 7 moves down at this time, then
Spool 5 is squeezed so that spool 5 declines is sealed blocking inside bottom valve body 2, so as to be reduced or turned off balanced valve, conversely, adjusting
