Abstract
The utility model discloses a butt clamp bivalve swing check valve, which comprises a valve body, a valve block and a pin shaft. The valve block is formed by a pair of semicircular discs which are matched with each other in a rotating connection mode through the pin shaft disposed at the straight-side ends of the discs. The pin shaft is fixed on the valve body respectively through supporting devices disposed at both ends of the pin shaft. Each supporting device is provided with an upper hole and a lower hole in the longitudinal direction. The pin shaft is fixed in the lower hole, a fixing pin penetrates through the upper hole, and the inner end of the fixing pin is fixed on the inner wall of the valve body. The butt clamp bivalve swing check valve has the advantages of being reasonable in structural arrangement, compact in structure, low in cost and good in market competitiveness.
Description
Technical field
The utility model relates to a kind of safety check, specifically is meant a kind of Swing check valve, is meant a kind of to folder bivalve Swing check valve especially.
Background technique
Swing check valve is claimed one-way valve or check valve again; The category that belongs to safety check; Swing check valve is used for pipe-line system, leans on the power of the mobile generation of pipeline medium itself to realize opening and closing automatically, and belongs to a kind of automatic valve; Be mainly used in pure pipeline and industry, environmental protection, water treatment, tall building water-feeding & drainaging pipeline, stop the usefulness of medium reverse flow.
In the existing technology; The multiple various structure that has safety check realizes opening and the blocking-up medium counter flow, as: to folder bivalve rotary-open type, single-lobe rotary-open type and up-down non-return etc., wherein folder bivalve Swing check valve mainly is made up of valve body and valve plate; Be provided with valve seat in the through hole of valve body; Said valve plate is made up of the pair of semicircular shaped flap, and the straight flange end of two flaps is rotationally connected through a bearing pin, is arranged with torsion spring on the bearing pin; The two ends of torsion spring are positioned respectively to be used to improve the reaction velocity of valve on two flaps of both sides.During use, the following current meeting makes two flaps to folding to Open valve together, and adverse current then can make flap launch to form a full circle and throttle down.But the existing shortcoming that folder bivalve Swing check valve is existed is: it is fixing to need to use fastening pieces such as bolt, nut, rivet that bearing pin is positioned in the assembly process, and structure is compact inadequately.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming and defect that existing technology exists, and provide that a kind of structure is provided with rationally, compact structure, cost are low to pressing from both sides the bivalve Swing check valve.
For realizing above-mentioned purpose; The technological scheme of the utility model is a kind of to folder bivalve Swing check valve; Comprise valve body, valve block and bearing pin, said valve block is made up of a pair of semicircle butterfly plate, and the two constitutes the cooperation that is rotationally connected through the bearing pin that is arranged at butterfly plate straight flange end; Said bearing pin is fixed on the valve body through the supporter of being located at its two ends respectively; Described supporter is provided with hole and following hole in the vertical, and described bearing pin is fixed on down in the hole, is equipped with the inner on the described upward hole and is fixed on the fixing pin on the valve interior wall.Through this setting, utilize fixing pin that supporter is fixed on the valve body, simple and compact for structure, processing cost is low.
Further being provided with is to be arranged with torsion spring on the bearing pin, and the two ends of torsion spring are positioned respectively on two butterfly plates of both sides.This setting has improved the reaction velocity of valve block.
Further being provided with is detachably to be set with suspension ring on the described valve body.Through this setting, make things convenient for the scene of the utility model to install and use.
The anti-collision block of the convexity of mutual correspondence that further is provided with that to be described two butterfly plates be provided with on it opens the side of direction.Through this setting, help to protect two butterfly plates under open mode, to collide each other and the appearance damage, improved life of product.
The utility model has the advantages that: structure is provided with rationally, compact structure, cost are low, and the market competitiveness is good.
Below in conjunction with Figure of description and embodiment the utility model is done further introduction.
