Abstract
The utility model relates to a deadening non-return valve, which comprises a valve body and a valve cap component. A water inlet of the valve body is provided with a valve mouth with a shaft sleeve. The valve cap component comprises a valve cap and a guiding post, a heterotype rubber ring and a pressing ring are orderly arranged on the lower end surface of the valve cap, and the upper end of the guiding post is connected with an inserting hole of the guiding post on the valve cap by threads. A spring is sheathed on a guiding rod of the valve cap which is arranged above the valve mouth, the guiding post is inserted into the shaft sleeve on the valve mouth, and the upper end of the guiding rod is inserted into a shaft sleeve on the valve body. The utility model has the advantages of beautiful appearance, no water impacting sound, good tightness and long service life. The utility model not only can be vertically installed, but also can be horizontally installed.
Description
The utility model relates to a kind of valve, particularly relates to a kind of check valve that is installed in the heating water circulation system.
Safety check on supply channel has at present: rotary-open type, rise-fall type etc., and through using checking that following shortcoming is arranged for many years: 1, the penetralia event often appears fitting badly in valve port; 2, water attack sound is too big during cut-off valve.These two shortcomings have brought very big loss and worry for vast user, as remain silent and sternly can not cause a large amount of water (energy) to run off, as it is just bigger to be used in the heating system loss, the water of one left alone without help pumping system runs off in a large number, then can cause " turned letter " to heating system, make a large amount of " heat energy " losses in vain, make the user can not get desirable heating, water attack noise and vibration meeting bring engine-damaged accident etc. to pipe network when closing in addition.
The purpose of this utility model, be at the problems referred to above provide that a kind of valve cuts out tightly, no backwater and do not have the noise reduction formula check valve of water attack sound, beautiful shape.
The purpose of this utility model adopts following technical proposals to realize, that is:
Noise reduction formula check valve comprises valve body, valve port, valve gap assembly, spring.Valve body middle valve wall is a spheric structure, and valve body water outlet place is provided with axle sleeve, and axle sleeve is connected with valve body by a plurality of gussets.Valve body, gusset, axle sleeve are the overall structure of one-step casting moulding.The valve port middle part is provided with axle sleeve, and axle sleeve is connected with valve port by a plurality of gussets.This axle sleeve, gusset, valve port are the overall structure of one-step casting moulding.Valve port is connected with the water intake inwall of valve body with screw thread.The valve gap assembly comprises valve gap, special-shaped cushion rubber, trim ring, guide rod, guide pillar and spring.Valve gap lower end surface outer rim has dovetail groove, and there is tapped guide pillar jack at its middle part.Special-shaped cushion rubber is arranged on the lower end surface of valve gap, and edge is connected with the dovetail groove coupling of valve gap lower end surface outer rim outside this abnormal shape cushion rubber.Trim ring is provided with on the lower end surface of special-shaped cushion rubber, and insert in the guide pillar jack of valve gap the upper end of guide pillar, and connects with screw thread and guide pillar jack, and valve gap, special-shaped cushion rubber, trim ring are fixed together.Fixedly connected with valve gap in the lower end of guide rod, valve gap, guide rod also can be overall structure.Spring housing is contained on the guide rod.The valve gap assembly is arranged on valve port top, and insert respectively in the axle sleeve at the axle sleeve at valve body water outlet place and valve body water outlet place its guide pillar lower end, guide rod upper end.
In order to improve sealability, on valve inleting water mouth inwall, have annular groove, the O RunddichtringO is housed in annular groove.
The utility model beautiful shape, middle part are spheric structure and reduce fluid resistance.Because the guide rod and the guide pillar of valve gap move up and down in axle sleeve respectively, and this valve both can vertically be installed, and also can horizontally install.The special-shaped cushion rubber good buffer effect of valve gap, good airproof performance, and can eliminate noises such as water attack sound.The utility model also has advantages such as long service life.
Fig. 1 is a kind of example structure schematic representation of the present utility model.The utility model is described in further detail below in conjunction with accompanying drawing.
Noise reduction formula check valve comprises valve body 1, valve port 2 and valve gap assembly.The middle valve wall 3 of valve body 1 is sphere shape, and water outlet 4 places of valve body 1 are provided with axle sleeve 5.Axle sleeve 5 is connected with valve body 1 by a plurality of gussets 6.Axle sleeve 5, gusset 6 and valve body 1 are the overall structure of one-step casting moulding.Valve port 2 middle parts are provided with axle sleeve 7, and axle sleeve 7 is connected with valve port 2 by a plurality of gussets 8.Valve port 2, gusset 8 and axle sleeve 7 are the overall structure of one-step casting moulding.Valve port 2 connects with the water intake 9 of valve body 1 with screw thread.Annular groove 10 is arranged on the valve port 2, in the annular groove 10 of valve port 2, be equiped with O RunddichtringO 19.The valve gap assembly comprises valve gap 11, special-shaped cushion rubber 12, trim ring 13, guide rod 14, guide pillar 15 and spring 16.Valve gap lower end surface outer rim has dovetail groove 17, and there is guide pillar jack 18 at its middle part.Special-shaped cushion rubber 12, trim ring 13 are successively set on the lower end surface of valve gap 11, and insert in the guide pillar jack 18 guide pillar 15 upper ends, and connect with it with screw thread, and trim ring 13, special-shaped cushion rubber 12 are fastened on the valve gap 11.Fixedlying connected with valve gap 11 in guide rod 14 lower ends, and is an overall structure.Spring 16 is sleeved on the guide rod 14, and insert in the axle sleeve 5 guide rod 14 upper ends, and valve gap 11 is arranged on the top of valve port 2, and guide pillar 15 inserts in the axle sleeve 7, and when valve was in closed condition, special-shaped cushion rubber 12 was sealed on the valve port 2.
