Lid overall construction intensity.It is preferred that said structure block, sealed base and side rack are integrally formed.
Preferably, the block structure is equipped with chamfering, the Comecting structure with ramps block bottom surface of the chamfering and side rack bottom surface.By
Contacted in block structure bottom with valve seating, the setting of chamfering can to avoid valve deck in rotary course because corner is excessively sharp and valve
The stop that seated connection is touched and generated, the rotary motion for making valve deck are more smooth.
Preferably, the surface at the top of the side rack is flushed with the top surface of sealed base, and the thickness of side rack is close
Seal the 9/11 of base thickness.Ensure that side rack has certain thickness, structural strength is enough, avoids being broken.
Preferably, the surface at the top of the side rack is flushed with the top surface of sealed base, the runner clearance opening
Spacing is 1.5-2mm.
Preferably, the opening of the inlet channel is in sector.
Compared with prior art, the valve deck of the diaphragm gas meter rotary valve of above-mentioned technical proposal is employed, have has as follows
Beneficial effect：
First, using the utility model diaphragm gas meter rotary valve valve deck, by the sealing bottom of inlet channel one side
Runner gap is set on seat so that a part of air-flow can enter inlet channel out of runner gap, reduce valve deck side wall pair
In the influence of air-flow, crushing is reduced so that gas flowing is more smoothly.
2nd, runner gap setting reduces valve deck overall deformation, improves quantification stability.

Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of valve deck of diaphragm gas meter rotary valve, including sealed base 1, sets in sealed base 1
There is inlet channel 4, sealed base 1 offers runner gap 20, and runner gap 20 is connected with inlet channel 4,20, runner gap
In 1 bottom of sealed base, runner gap 20 forms the notch for not contacting valve seating with 1 bottom of sealed base.Inlet channel 4 is open
Side rack 2 is left in outside, and side rack 2 is in lath-shaped, and side rack 2 is located above notch, and 2 both ends of side rack connect with sealed base 1
It connects.
A part of air-flow can enter in inlet channel 4 out of runner gap 20, reduce valve deck side wall for air-flow
It influences, reduces crushing so that gas flowing is more smoothly.
Simultaneously as notch causes side rack 2 not contacted with valve seating 5, contact area is effectively reduced, reduces friction,
Rotate valve deck more smooth.
1 upper surface of sealed base is additionally provided with multiple gussets 3 for being used to increase structural strength, and the opening of inlet channel 4 is located at
1 surface of sealed base between adjacent webs 3.Reasonably using gusset 3, using gusset 3 as the inner wall of inlet channel 4, improve
The length of valve deck upper air passage, becomes apparent the separation of inlet channel 4.
As shown in Figure 5 and Figure 6,2 bottom of side rack is equipped with to increase knot of the side rack 2 with 1 bonding strength of sealed base
Building block 10,10 bottom surface of block structure are flushed with 1 bottom surface of sealed base, and block structure 10 connects 2 bottom of sealed base 1 and side rack, and
Above-mentioned three is integrally formed.2 end of side rack is increased with the connection thickness of sealed base 1 by block structure 10, is effectively carried
The fixing intensity of high side rack 2, avoids side rack 2 from being broken.
Secondly, if block structure 10 easily contacts with valve seating 5 there are sharp edge or wedge angle, causes valve deck stuck or rotate
Vibrations are generated in the process, therefore block structure 10 is additionally provided with chamfering 11,10 bottom of Comecting structure with ramps block of chamfering 11 in the present embodiment
2 bottom surface of face and side rack makes entire valve deck rotation more smooth steady.
The surface at 2 top of side rack is flushed with the top surface of sealed base 1, and the thickness of side rack 2 is thick for sealed base 1
The 9/11 of degree.Ensure that side rack 2 has certain thickness, structural strength is enough, avoids being broken.
The surface at 2 top of side rack is flushed with the top surface of sealed base 1, and runner gap 20 is open spacing as 1mm.
The sector that the opening of inlet channel 4 is justified in 1/4 provides the bore of sufficiently large air inlet, meets the needs of air inlet.
The above makes the preferred embodiment of the utility model, does not depart from for those of ordinary skill in the art
On the premise of the utility model principle, several variations and modifications can also be made, these also should be regarded as the protection of the utility model
