Abstract
The utility model discloses a kind of novel noise eliminating check valves, it mainly include valve body, bracket etc., the water outlet end of bracket connection valve body, guide copper sleeve is inlaid in the centre pilot hole of bracket, the left end of connection valve rod in guide copper sleeve, valve rod passes through the centre pilot hole of flap, spring is provided between flap and bracket, gasket is fixed on flap by guide pressing plate, flap, gasket, guide pressing plate is fixed on valve rod, guide pressing plate right end setting simultaneously is in contact there are three positioning and guiding pawl with the inlet end of valve body, sealing ring is installed between gasket and valve body.The utility model guiding accuracy is high, it is possible to prevente effectively from corrosion, reduces guiding resistance;Sealing surface more sealed reliable, bond strength is high, long service life;It is designed using full flow, medium fluid resistance is small, thus medium is small by the head loss of entire damping check valve, and energy-saving effect is good;It can voluntarily be adjusted by hydraulic pressure in the course of work, eliminate noise.
Description
Technical field
The utility model relates to the fields of valve, and in particular to a kind of novel noise eliminating check valve.
Background technique
Traditional check-valves guiding accuracy is low, and guiding resistance is big, is easy to appear corrosion.And traditional design sealing surface is inadequate
Reliably, lead to problems such as to be easy to appear corrosion, plastic-spraying epoxy resin falls off so that the service life of equipment is short;Traditional design is logical
Head loss is big when crossing valve, and energy dissipation is serious, and noise is big.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of novel noise eliminating check valve.
The purpose of this utility model is completed by following technical solution: this novel noise eliminating check valve, main to wrap
Valve body, bracket, guide copper sleeve, spring, valve rod, flap, guide pressing plate, gasket, sealing ring are included, bracket connects the water outlet of valve body
Mouthful end is inlaid with guide copper sleeve in the centre pilot hole of bracket, and the left end of connection valve rod, valve rod pass through flap in guide copper sleeve
Centre pilot hole is provided with spring between flap and bracket, gasket is fixed on flap by guide pressing plate, flap, sealing
Pad, guide pressing plate are fixed on valve rod, while there are three the inlet ends of positioning and guiding pawl and valve body for the setting of guide pressing plate right end
It is in contact, sealing ring is installed between gasket and valve body.
Guide copper sleeve is inlayed in the bracket, is moved to guides stem.
It is provided with shaft shoulder installation positioning flap on the valve rod, and controls the stroke of flap unlatching.
The sealing ring is the copper ring being individually embedded in valve body dovetail groove.
The inner flow passage and flap opening travel of the check-valves are all made of full flow design.
The utility model has the following beneficial effects:
1, the utility model guiding accuracy is high, it is possible to prevente effectively from corrosion, reduces guiding resistance;Sealing surface more seals can
It leans on, bond strength is high, long service life.
2, the utility model is designed using full flow, and medium fluid resistance is small, thus medium passes through entire damping check valve
Head loss it is small, energy-saving effect is good;It can voluntarily be adjusted by hydraulic pressure in the course of work, eliminate noise.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols: valve body 1, bracket 2, guide copper sleeve 3, spring 4, valve rod 5, flap 6, guide pressing plate 7, clamp screw
Female 8, spring shim 9, gasket 10, sealing ring 11.
Specific embodiment
Detailed introduction is done to the utility model below in conjunction with attached drawing:
Embodiment: as shown in the picture, this novel noise eliminating check valve mainly includes valve body 1, bracket 2, guide copper sleeve 3, bullet
Spring 4, valve rod 5, flap 6, guide pressing plate 7, gasket 10, sealing ring 11, bracket 2 connect the water outlet end of valve body 1, bracket 2
Guide copper sleeve 3 is inlaid in centre pilot hole, the left end of connection valve rod 5, the center that valve rod 5 passes through flap 6 are led in guide copper sleeve 3
Xiang Kong, is provided with spring 4 between flap 6 and bracket 2, gasket 10 is fixed on flap 6 by guide pressing plate 7, flap 6, close
Packing 10, guide pressing plate 7 are fixed on valve rod 5, while there are three positioning and guiding pawls and valve body 1 for the setting of 7 right end of guide pressing plate
Inlet end is in contact, and sealing ring 11 is equipped between gasket 10 and valve body 1.
Guide copper sleeve 3 is inlayed in the bracket 2, is moved to guides stem 5, guiding accuracy is improved and avoids corroding, reduce
It is oriented to resistance.
It is provided with shaft shoulder installation positioning flap 6 on the valve rod 5, and controls the stroke of the unlatching of flap 6, when flap 6 is opened
After in place, the shaft shoulder being arranged on valve rod 5 can contact the right end of bracket 2,6 stroke end of flap, damping check valve standard-sized sheet.
The sealing ring 11 is the copper ring being individually embedded in 1 dovetail groove of valve body, sealing surface more sealed reliable, in conjunction with strong
Degree is high, long service life.
The inner flow passage and 6 opening travel of flap of the check-valves are all made of full flow design, and medium fluid resistance is small, because
And medium is small by the head loss of entire damping check valve, energy-saving effect is good.
4 material of spring is 304 stainless steels, accurately calculates operating pressure when 4 installation pretightening force of spring and standard-sized sheet, makes
This damping check valve passes through hydraulic pressure during the work time and voluntarily adjusts, and eliminates noise, optimizes damping check valve performance.
It is understood that it will be understood by those skilled in the art that the technical solution of the utility model and utility model structure
Think of is subject to equivalent substitution or change all and should belong to the protection scope of the utility model the attached claims.
