Abstract
The utility model belongs to the technical field of the valve control, and particularly relates to a non-return core, which comprises a non-return core main body (4) and a seal ring (1) which is arranged outside the valve core main body, and is characterized in that: a liquid passage of the non-return core main body (4) is provided with a rubber seal gasket (2), the outer side of the rubber seal gasket (2) is provided with a stop rod for limiting the dropping of the rubber seal gasket, and the stop rod (3) is fixed inside the valve core main body. The non-return core can be matched with a valve or a pipe fitting to use. The non-return core has a simple, reasonable and compact structure, is simple to process, has a good non-return effect, saves cost, has a long service life, and is easy to be popularized to use.
Description
Technical field
The utility model belongs to technical field of valve control, the non-return core that is specifically related to supply water, uses in other media control system such as air feed, fuel feeding.
Background technique
In the prior art, in order to prevent the mutual pollution of different pipe-line systems, non-return spool is set in the pipeline of being everlasting, non-return spool generally comprises spool main body and sealing gasket, and disease leans sealing gasket on sealing surface by guide rod and the spring that is nested with at guide rod.This check valve cored structure complexity, longer dimension design this when being contained in the body interior of valve or pipe fitting need consider sufficiently long space, is unfavorable for the design and the cost control of product.
Summary of the invention
The utility model is intended to solve prior art complex structure, the excessive defective of boundary dimension, and the non-return core of a kind of compact structure, simple, space-saving is provided.
At above essential technique problem, the corresponding technical solution scheme of the utility model is:
A kind of non-return core, comprise non-return core main body and be positioned at the outer seal ring of spool main body, the liquid chunnel that it is characterized in that non-return core main body is provided with a rubber sheet gasketing, and the outside of rubber sheet gasketing is provided with the stop rod that the restriction rubber sheet gasketing comes off, and stop rod is fixed in the spool main body.The utility model is by being fixed on the unlatching of the stop rod control gasket seal on the main body, because gasket seal is an elasticity flexible glue body, in the medium forward flow, the pressure of liquid and stop rod make gasket seal bending distortion, and liquid stream passes through smoothly, when control system close or medium when flowing backwards gasket seal recover shape, sealing paste is combined on the channel seal face, stop rod is a radial arrangement, and the little so whole non-return core main body of spacer thickness can be provided with very little, can satisfy.
As the conversion mode of execution to above technological scheme, rubber sheet gasketing is provided with groove, and stop rod is stuck in the groove.Such structure can prevent effectively that rubber sheet gasketing from coming off under the effect of hydraulic pressure.The utility model stop rod set-up mode has multiple possibility, can be arranged on only spool main body inner wall side to stop rod; Also can fix stop rod by other machining manufactures.
From art designs and technology pluses and minuses aspect that manufacturing influenced, the oral area of described non-return core main body is provided with support, and support is made up of the pole of radial radiation.
As the further optimization to above mode of execution, the annular end face of an end of non-return core main body is provided with dentation anticreep inserted part, and the dentation of anticreep inserted part is from outside oblique the extending to form of end face.
Equally, from art designs and technology pluses and minuses aspect that manufacturing influenced, non-return core main body is provided with the mounting hole of circumference symmetry, and stop rod passes fixing from mounting hole, and seal ring set places the outer end of stop rod.
Only spool compared to existing technology, the utility model is realized non-return function according to the elasticity of gasket seal, only need the gasket seal location not to be come off at one side applying design one stop rod of gasket seal, have simple and reasonable for structure, compact, using effect is good, the beneficial effect of long service life, and processing is simple, produce this saving, be easy to promote the use of.
Description of drawings
Fig. 1 is the non-return core embodiment's 1 of the utility model a structural representation;
Fig. 2 is the assembling schematic representation of Fig. 1;
Wherein, 1 be seal ring among Fig. 1 and Fig. 2; 2 is rubber sheet gasketing; 3 is stop rod; 4 is non-return core main body.
Embodiment
Non-return core illustrated in figures 1 and 2, in fluid control field and valve or the supporting use of pipe fitting, this non-return core comprises non-return core main body 4 and is positioned at the outer seal ring 1 of spool main body, the liquid chunnel of non-return core main body 4 is provided with a rubber sheet gasketing 2, the outside of rubber sheet gasketing 2 is provided with the stop rod that the restriction rubber sheet gasketing comes off, and stop rod 3 is fixed in the spool main body.Stop rod is a pin in the present embodiment, and radial arrangement has groove on the circumferential surface of rubber sheet gasketing, and stop rod is stuck in the groove.
Non-return core main body 4 is the injection molded hard valve body of one, and the oral area of non-return core main body 4 is provided with support, and support is made up of the pole of radial radiation.The annular end face of the non-return core main body the other end one end is provided with dentation anticreep inserted part, and the dentation of anticreep inserted part is that the inserted part can further improve the anticreep performance when being connected to valve or main pipe body from outside oblique the extending to form of end face.This dentation anticreep inserted part also can the peripheral hardware annex such as collar, jump ring, pin etc.
Non-return core main body 4 is provided with the mounting hole of circumference symmetry, and stop rod 3 passes fixing from mounting hole, and seal ring 1 is placed on the outer end of stop rod 3.Seal ring 1 is fixing moving bar 3 after assembling, and after non-return core main body is installed on valve or main pipe body, the sealing of main wall and link is fitted.
During use, open system valve, rubber sheet gasketing are subjected to the thrust of the pressure and the stop rod 3 of water simultaneously, rubber sheet gasketing 2 distortion, and water enters by the space of distortion from inlet and flows, and non-return core is opened work.Stop rod 3 is placed in rubber sheet gasketing 2 grooves, and is fixed in the non-return core main body 4, prevents that rubber sheet gasketing 2 from coming off under the effect of hydraulic pressure.The anti-stop rod 3 in the outside that seal ring 1 is enclosed within non-return core main body 4 comes off.When non-return core is installed in the system, seal ring 1 also with the closely connected seal action that plays of channel wall.Rubber sheet gasketing 2 resiles and plays non-return effect when system closing or medium refluence.
In sum, after those of ordinary skill in the art reads file of the present invention, need not creative mental labour according to the technical solution of the utility model and technical conceive and make other various corresponding conversion scheme, all belong to the scope that the utility model is protected.
