Abstract
The utility model relates to a silencing ball core check valve. The utility model is composed of a valve body, a valve core, a liquid outlet, a liquid inlet, etc. The utility model is characterized in that the liquid inlet of the valve body is provided with a ball seat; one end of the ball seat is a cylinder, and the other end of the ball seat is a trumpet-shaped columnar body; the liquid outlet of the valve body is provided with a ball core frame; one end of the ball core frame is a cylinder which is provided with a liquid outlet hole, the other end of the ball core frame is a claw-shaped body, and the middle part of the ball core frame is a supporting rod; the valve core is a spherical body, and the valve core is arranged between the trumpet-shaped columnar body of the ball seat and claw sheets of the ball core frame. The abrasion resistance degree of the valve core of the check valve is improved, the service life of the check valve is correspondingly improved, the ball seat and the ball core frame on the valve core are in elastic contact, and the noise is furthest reduced when the check valve works.
Description
The utility model relates to safety check, especially a kind of noise elimination ball core valve last time.
Use more safety check that swing safety check and triangle positioning pawl formula safety check are arranged at present.The swing safety check is to swing the unidirectional of control valve to open by spool, and triangle positioning pawl formula safety check is to come to the spool location to reach the unidirectional purpose of opening by the triangle pawl on the spool, both all have sealing gasket shortcoming easy to wear on the spool, and all can produce very big noise during their work, working life is short, needs often maintenance.
The purpose of this utility model just provides that a kind of noise is little, the noise elimination ball core safety check of long service life.
The utility model purpose is realized by following technological scheme:
Noise elimination ball core safety check comprises valve body, spool, liquid outlet, liquid entering hole, and the liquid entering hole place of valve body is provided with ball seat, and ball seat one end of hollow is a cylindrical body, and the other end is horn-like cylinder.The liquid outlet place of valve body is provided with ball core frame, and ball core frame one end is a claw shaped body, and the other end is a cylindrical body, has liquid outlet opening on it, and the centre is a strut.Spool is a spherosome, can adopt elastic material such as rubber to make, and it is placed between the calvus of horn-like cylinder of ball seat and ball core frame.
Noise elimination ball core check valve spool of the present utility model is a spherosome, its wear-resisting property improves greatly, corresponding working life of also improving whole valve, because spool is that elastic material is made, and be placed between horn-like cylinder and the calvus, itself and ball seat and ball core are Elastic Contact, the noise when therefore farthest having reduced safety check work.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model structural representation;
Fig. 3 is the structural representation of ball core frame;
Fig. 3 is a ball core shelf structure schematic representation.
Noise elimination ball core safety check comprises valve body 1, spool 3, liquid outlet 7, liquid entering hole 8, liquid entering hole 7 places of valve body 1 are provided with ball seat 9, and the ball seat 9 of hollow adopts copper or plastics to make, and the one end is a cylindrical body, the other end is horn-like cylinder, and cylindrical body end and valve body 1 liquid entering hole place stick with glue and connect.Liquid outlet 7 places of valve body 1 are provided with ball core frame 5, and ball core frame 5 one ends are the claw shaped body of band calvus 3, and the other end is a cylindrical body, has liquid outlet opening 6 on it, and the centre is a strut 4, and the cylindrical body end of ball core frame 5 and valve body 1 liquid outlet place are for closely cooperating.Spool 3 is a spherosome, adopts rubber to make, and it is placed between the calvus 3 of the horn-like cylinder of ball seat 9 and ball core frame 6.
As Fig. 1: ball core frame 5 one ends are the claw shaped body of band calvus 3, and the other end is a cylindrical body, and 6, strut 4 two ends of liquid outlet opening that have on it more than three or three connect claw shaped body and cylindrical body center respectively.
As Fig. 2: ball core frame 5 one ends are the claw shaped body of band calvus 3, and the other end is a cylindrical body, and its middle part has liquid outlet opening 6, and strut 4 one ends link to each other with the claw shaped body center, and to be that triangle is forked link to each other with cylindrical body the other end.
As Fig. 3: ball core frame 5 one ends are the claw shaped body of band calvus 3, and the other end is that cylindrical body, its middle part have strut 4 two ends of liquid outlet opening more than 6, three or three and connect claw shaped body and cylindrical body respectively.
During the work of noise elimination ball core safety check, when liquid enters from liquid entering hole 8, liquid is washed spherosome spool 2 open by the ball seat 9 of hollow, flow in the valve body 1, and the liquid outlet opening from the ball core frame 56 flows out valve bodies 1, and when the liquid outlet opening 6 of liquid from ball core frame 5 entered valve body 1, liquid poured spherosome spool 2 in the horn-like cylinder of ball seat 9, and, realize non-return with the obstruction of the cylinder bore in the ball seat 9.
