Abstract
Provided is a noise abatement check-valve for clamp connection which is characterized in that the valve body junction at the water inlet of the check-valve and the valve cover junction at the water outlet of the check-valve are both designed with a ring of groove that can be in clamp connection with the clamp and the caliber and the cross section of the groove match with the caliber and the cross section of the clamp junction. The utility model changes the traditional connection method of the check-valve body and the check-valve cover with pipelines, that is, adopts the clamping connection method having flexible connecting effects instead of the rigid connection method of pipe thread or flange, thereby facilitating to overcome the resonance problem and the leakage problem of pipelines and making the site operation simple and convenient. Additionally, between the valve core seat of the valve core and the valve seat of the valve body is provided an anti-collision rubber sealing ring, beneficial to noise abatement.
Description
Technical field
The utility model relate to a kind of in the pipeline of conveyance fluid medium the designing technique of used safety check, particularly a kind of damping check valve that is suitable for clip connected.
Background technique
The present safety check that in the pipeline of water supply network conveying or other flowing mediums, generally adopts (or claiming one-way valve), (mode of connection of) linking department and pipeline all is to adopt pipe thread or flange (dish) Placement or up and down at its valve body two, above-mentioned two kinds of Placements are all and are rigidly connected, this be because: wherein pipe thread connects the outside thread (or internal thread) that is meant with pipeline and is connected with the internal thread (or outside thread) of corresponding valve body (or valve gap) joint, the area of contact of both junction surfaces is very big, and its character result can only be the connection of rigidity; Flange connection wherein is meant that the pipeline joint is designed to flange plate structure, corresponding valve body (or valve gap) joint also is a flange plate structure, when pipeline construction is installed, is to connect two flange plate with bolt, the area of contact of both junction surfaces also is very big, and its character result is rigidly connected.The pipeline that above-mentioned two kinds of rigidly connected shortcomings are to cause to form pipeline in use can cause the common shake of whole pipe-line system when running into local vibrations, if things go on like this, cause pipe leakage easily.And when adopting pipe thread or flange to be connected installation, on-site construction operations is trouble, also more time-consuming taking a lot of work during maintenance.
In addition: the general only custom of existing clip connected part is used for being connected between pipeline and the pipeline, yet there are no to be used for and being connected of safety check.
In addition, because of the reason of valve core structure, in use there are the collision vibrations in present safety check (or claiming one-way valve) and the shortcoming of trigger noise.
The model utility content
The purpose of this utility model is a kind of damping check valve (also claiming one-way valve) that is suitable for clip connected of design, and it can realize flexibly connecting, and favourablely overcomes common shake problem and leakage problem, and construction and regular maintenance are simple and convenient.
The purpose of this utility model also is to design a kind of effective safety check of eliminating the noise, and can overcome the collision vibrations in use and the noise of initiation.
The utility model is to adopt following technological scheme to realize: this kind is suitable for the damping check valve of clip connected, still comprise a valve body, a valve gap, a spool, be sleeved on the Returnning spring on the spool, it is characterized in that: valve body joint that is positioned at the safety check water inlet and the valve gap joint that is positioned at safety check water outlet place all design a circle can with the clip groove of clamping (or claim draw-in groove) mutually, the bore of this groove and transverse section (being cross section) is suitable with the bore and the transverse section of clip connected portion.
The utility model is also established an anti-collision rubber seal between the valve seat of the valve core case of spool and valve body, help producing the noise elimination effect.
The beneficial effects of the utility model: the utility model technology has changed the Placement of conventional check valves valve body and valve gap and pipeline, promptly abandon the mode that is rigidly connected that adopts pipe thread or flange plate, and employing has the clip connected mode of the effect of flexibly connecting, this is because not only can play connection and supporting effect with the connection of clip connected part, in the clip connected part, contain soft C type rubber seal, clip is that the rubber seal by ductility is connected and sealed safety check and pipeline, can produce and flexibly connect effect, favourablely overcome pipeline and shake problem and leakage problem altogether, and site operation is simple and convenient.
In addition between the valve seat of the valve core case of spool and valve body, establish an anti-collision rubber seal, help producing the noise elimination effect.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model a structural representation.
Wherein: 1～valve gap, 2～spool, 3～valve body, 4～O RunddichtringO, 5～Returnning spring, 6～anti-collision rubber gasket, 7～Cock screw, 8～valve core case, 9～valve seat, the valve gap joint at 10～water outlet place, 11～valve gap joint groove (or claiming draw-in groove), the valve body joint of 12～water inlet, 13～valve body joint groove (or claiming draw-in groove), 14～clip, 15～be used for the lock bolt of clip, 16～connected pipe, 17～clip connected portion, the C type rubber seal in 18～clip.
Embodiment
With reference to accompanying drawing 1 as can be known, this damping check valve that is suitable for clip connected that this usefulness is novel, comprise a valve body 3, a valve gap 1, a spool 2, be sleeved on the Returnning spring 5 on the spool, valve body joint 12 that is positioned at the safety check water inlet and the valve gap joint 10 that is positioned at safety check water outlet place all design have a circle can with clip 14 groove 13,11 of clamping mutually, the bore of this groove 13,11 and transverse section (cross section) are suitable with the bore and the transverse section of clip connected portion 17.
The utility model is also established an anti-collision with rubber seal 6 between the valve seat 9 of the valve core case 8 of spool and valve body, help producing the noise elimination effect.
Connection process of the present utility model and working principle: the joint of the pipeline that is connected with this safety check two ends also should offer and be suitable for the clip groove of clamping (or claiming draw-in groove) mutually, during installation, the same with prior art: the intake-outlet place of piping connection portion to be connected not being aimed at the safety check two ends, cover connects C type rubber seal 18, be connected on the groove of joint with clip again, with lock bolt 15 clip 14 lockings got final product at last.When current when valve body 3 inlet end of safety check enter, water pressure is greater than the pressure of Returnning spring 5, so case 8 is backed down together with rubber gasket 6, the water outlet of water intake and valve gap 1 is connected, make water conduction, when valve body 3 inlet end do not have current, Returnning spring 5 is under elastic pressure and the hydraulic pressure acting in conjunction of water outlet place, valve core case 8 and rubber gasket 6 thereof are pressed on the sealing surface of seat of valve body 3, stay in the valve body and can't oppositely drain, play water emptying in the prevention pipeline with the interior water of pipeline.
Of the present utility modelly do not state part identical with prior art.
