Abstract
The utility model relates to an omnibearing check valve which comprises a valve body, a valve plug, a sealing ring, etc. The utility model is characterized in that the inner wall of the valve body is provided with a groove-shaped channel, a pressure spring is arranged between the valve plug and the back plug cover of the valve, and the O-shaped sealing ring is fixed on the contacting position of the valve plug and the valve body. When the utility model is installed, the self of the valve body can be installed on any space position if only a water outlet and a water inlet are aimed to the outside. The omnibearing check valve also has the advantages of small volume, simple structure, convenient installation, good technological property, etc.
Description
The utility model belongs to valve class technical field, specifically a kind of improvement of safety check.
As everyone knows, the safety check of present domestic use roughly has two kinds: a kind of is to adopt the single valve plate, the another kind of pair semicircle valve plates that adopt.Former structure is simpler, but using effect is poor, and latter's structure is complicated, although using effect is better than the former, but service time one is long, and fluid pressure changes greatly, backwater (leaking) phenomenon just can occur, reason is: the pressure one of two semicircle valve plate sealings in the valve body is by the valve shaft stage clip, and two by fluid pressure; Long when service time one, fluid pressure is little, and stage clip is not the middle that fixedly is pressed in valve plate, only is pressed in 1/2nd places outside the valve plate center, the build-up of pressure inequality, thus influenced sealing effect.Above-mentioned in addition safety check is relatively stricter in the requirement of mounting point, otherwise influences using effect.
The purpose of this utility model provides a kind of good sealing effect, and is simple in structure, is applicable to the comprehensive formula safety check of any installation.
The purpose of this utility model is achieved in that it includes valve body, valve obstruction, seal ring, it is characterized in that on the inwall of valve body, having the groove shaped passage, be provided with a stage clip between the blanking cover behind valve obstruction and the valve, on valve obstruction and the contacted position of valve body, be fixed with one zero RunddichtringOs.During use, this safety check is installed in the pipeline, pressure by liquid in the pipeline stops up valve and backs down and together compress with stage clip in the valve body, make flow of liquid cross the groove shaped passage, and the through hole on the blanking cover and by this valve, when refluxing, stage clip stops up valve and pushes back original position in the valve behind the valve, return pressure is big more, and the valve plug for seal is tight more.
The utility model is because inner-cavity structure adopts plunger conical surface seal formula, and its installation conditions has direction requires except entery and delivery port, and valve body itself can be installed any spatial position, and promptly the valve body axle center can 360 ° of rotations, and it is all unaffected to tilt arbitrarily.The appearance of this check valve design is to adopt two flange non-return butterfly valve profiles, valve body length is by national BG12238-89 regulation, have the advantages that volume is little, simple in structure, easy for installation, technology capability is good, more reasonable more reliable on sealability than existing safety check.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is a sectional structure schematic representation of the present utility model.
Referring to Fig. 1,1 is two flange check valve body, one valve is housed in the ingress of valve body 1 inboard stops up 4, on entering the mouth contacted position, valve obstruction and valve body inlay one zero RunddichtringOs 3, the valve outlet end have one be fastened on the valve body by screw and the middle part have the valve of through hole after blanking cover 7, valve stop up with valve after be provided with a pressure spring 5 and be embedded in valve obstruction and valve between the blanking cover after in the restraining groove of blanking cover.The inwall of valve body periphery is provided with the recess channels 2 of liquid by this valve, also is evenly equipped with limit stiffening rib 6 in the recess channels 2.During use, should return earlier only that valve is installed in the pipeline on request, and when water supplying pump, utilize the water column velocity pressure that valve is stopped up and push open, the pressure spring compression, the current recess channels of flowing through then, the through hole behind the valve on the blanking cover flows out; When termination of pumping, valve is blocked in the sealing of rebounding immediately under the pressure spring effect, and simultaneously by pressure of return water, sealing effect can be better.
Claims (4)
1, a kind of comprehensive formula safety check of forming by valve body, valve obstruction, seal ring etc., it is characterized in that on the inwall of valve body, having the groove shaped passage, be provided with a stage clip between the blanking cover behind valve obstruction and the valve, on valve obstruction and the contacted position of valve body, be fixed with an O RunddichtringO.
2, safety check according to claim 1, it is characterized in that stage clip be embedded in valve stop up with valve after in the restraining groove of blanking cover.
3, safety check according to claim 1 is characterized in that the groove shaped passage on the valve interior wall is preferably the recess channels of inner peripheral wall.
4, safety check according to claim 1, it is characterized in that having behind the valve of through hole blanking cover by screw on valve body.
