Abstract
The utility model relates to a novel check valve, including the valve body, the coaxial system in valve body both sides has a flange, and one side of valve body is the liquid outlet side, and the opposite side be the liquid intake side, and the coaxial system of disk seat is at the valve body inner wall, and the valve body body cavity that lies in the liquid outlet side at the disk seat is equipped with the valve plate, the valve plate through round pin axle hinge dress on the valve body inner wall, it has an axial guide hole to make on the lateral wall that the valve body liquid outlet inclined, a guide pin bushing is adorned to coaxial inlaying in the guide hole, at coaxial set of shock mount of guide pin bushing, the length of spring is greater than the length of guide pin bushing, the elasticity tip of spring corresponds the side of valve plate. The application provides a novel check valve adopts a neotype spring application structure, with the spring mounting on the valve body, more traditional installing is compared on the valve plate, has the mounting means, changes simple advantage.
Description
Technical field
This utility model belongs to valve field, is a kind of non-return valve.
Background technology
Check-valves refers to rely on medium itself to flow and automatic open and close flap, is used for the valve preventing medium from flowing backwards,
Also known as non-return valve, check valve, reflux valve and counterbalance valve.Check-valves belongs to a kind of automatic valve, and it is mainly made
With being to prevent medium from flowing backwards, prevent pump and drive motor reversion, and the releasing of vessel media.
The flap of swing check valve rotates around the shaft.Its fluid resistance is generally less than lift check valve,
It is applicable to the occasion of larger caliber.Swing check valve can be divided into single-lobe swing type, double according to the number of flap
Lobe swing type and many lobes swing type three kinds.Single-lobe swing check valve applies in general to the occasion of medium caliber.Greatly
When bore pipeline selects single-lobe swing check valve, for reducing water hammer pressure, preferably with reducing water hammer pressure
Slow Close Valve.Double-disc swing check valve is applicable to medium-large caliber pipeline.To folder double-disc swing check valve
Structure is little, lightweight, is that one develops check-valves faster；Many lobes swing check valve is applicable to large-diameter pipe
Road.
By retrieval, finding that following patent documentation and the application dependency are relatively big, particular content is as follows:
CN202040382U is open a kind of to folder swing check valve, including valve body, spool, T-shaped connecting rod,
Localizer, connecting rod, jointed shaft, spool is arranged at the valve of valve body, and spool is by T-shaped connecting rod and connecting rod
Wherein one end be connected, the other end of connecting rod is arranged on localizer by jointed shaft, and localizer is arranged on valve body
Open slot in.
The open a kind of swing check valve of CN202215799U, valve seat is positioned at valve body, is positioned at valve body at valve seat
Endoceliac side is provided with flap, and flap is connected with rocking bar, and rocking bar is connected on valve body by bearing pin.
The application has carried out bigger improvement on the basis of above-mentioned patent, it is thus achieved that good effect.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of low cost, good seal performance,
The convenient modified model flange sluice valve with screw connected valve cover installed.
The technical scheme that this utility model realizes purpose is as follows:
A kind of non-return valve, including valve body, valve body both sides are the most integrally shaped with adpting flange, the side of valve body
For liquid outlet side, opposite side is liquid-inlet side, and the coaxial system of valve seat, at valve interior wall, is positioned at valve seat
Being provided with valve plate in the valve body body cavity of liquid outlet side, valve plate is contained on valve interior wall, at valve body liquid by bearing pin hinge
Being shaped with an axial guide hole on the sidewall of body outlet side, in guide hole, coaxial setting-in one guide pin bushing, shoots at guide pin bushing coaxial sleeve
Spring, the length of spring is more than the length of guide pin bushing, the side of the elastic ends correspondence valve plate of described spring.
And, embedded sealing ring on the sealing surface of valve seat.
The beneficial effects of the utility model are:
1, the non-return valve that the application provides uses a kind of novel spring compression structure, is arranged on by spring
On valve body, more traditional being arranged on valve plate is compared, and has mounting means, changes simple advantage.
2, the non-return valve that the application provides is applicable to various sizes of pipeline, and installation and removal are quick, with
Time there is simple in construction, futuramic feature.
Accompanying drawing explanation
Fig. 1 is the structural representation of the application.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following example are only
It is illustrative, is not determinate, it is impossible to limit protection domain of the present utility model successively.
A kind of non-return valve, including valve body 2, valve body both sides are the most integrally shaped with adpting flange 1, valve body
Side is liquid outlet side, and opposite side is liquid-inlet side 9, the coaxial system of valve seat 8 at valve interior wall,
Valve seat is positioned at the valve body body cavity of liquid outlet side and is provided with valve plate 6, and valve plate is contained in valve interior wall by bearing pin 5 hinge
On, the innovation of the application is:
The sidewall of valve body liquid outlet side is shaped with an axial guide hole 3, coaxial setting-in one guide pin bushing 10 in guide hole,
At guide pin bushing coaxial package spring 4, the length of spring is more than the length of guide pin bushing, the elastic ends correspondence valve plate of spring
Side, when valve plate spin-up, spring has certain pressure to valve plate, and after fluid passes through, spring is by valve plate
It is pressed on valve seat, stops fluid reflux, play the effect of non-return.
In the application, in order to increase the sealing between valve plate and valve seat, on the sealing surface of valve seat, setting-in seals
Circle 7.
