Abstract

The invention relates to a mute check valve, comprising a valve body, a valve seat arranged in the valve body, a valve clack, a valve rod connected with the valve clack, a guide body and a spring seat, wherein one end of the valve rod is supported on the guide body by bearings; the valve clack is closely contacted with the valve seat under the action of the spring seat; and a shock pad is arranged between the valve clack and the valve rod. In the mute check valve provided by the invention, the shock pad is additionally arranged between the valve rod and the valve clack, so that impact of inertia of the valve rod on the valve clack is reduced when the backflow is checked, and the breakage of the valve rod is prevented effectively at the same time.

Description

A kind of DRV
Technical field
The present invention relates to the manufacturing field of safety check in the mechanical engineering, particularly relate to a kind of DRV.
Background technique
Safety check is the primary element of fluid Control Engineering; It uses the extensive of ten minutes, but no matter traditional safety check is rotary-open type, rise-fall type, oblique butterfly check valve or DRV, and all there is a total shortcoming in they when opening and closing; Promptly open or close in the closed procedure; Flap is in accelerating process all the time, makes the valve motion parts stop preceding excessive velocities, the immediate cause that Here it is causes safety check water hammer and flap to clash into.For addressing the above problem, traditional DRV has been made following improvement, and its working principle is following: fluid is got into by the front end inlet on the valve body, the runner between the flap of flowing through, valve body and the deflector, the pipeline of entering valve rear end; When the rear end pipeline had water hammer to take place, the force flap of rear end moved towards the valve seat of front end, and the quick closedown valve seat cuts off the rear end fluid valve seat of flowing through and gets into the pipeline of valve seat front end, avoids the destruction of rear end water hammer to squelch type safety check front-end pipelines and equipment.
But, no any power apparatus that unloads between the valve rod of traditional DRV and the flap, thus make valve rod and flap wearing and tearing very fast, the working life of having reduced valve; Simultaneously, long-term vibrations make valve rod fracture easily itself.
Summary of the invention
The object of the invention provides a kind of DRV.
For achieving the above object, the technological scheme that the present invention adopts is:
A kind of DRV; Comprise valve body, be arranged on the valve seat, flap of described valve inner, valve rod, deflector and the spring seat that is connected with described flap; Bearings is passed through on described deflector in one end of described valve rod; Described flap closely contacts with described valve seat under the effect of spring seat mutually, is provided with beam between described flap and the valve rod.
Preferably, described valve body is wholely set with deflector mutually.
Further preferably, described valve body and deflector are through casting integrated moulding.
Preferably, described bearing is a linear bearing.
Because technique scheme utilization; The present invention compared with prior art has advantage and effect: the present invention is through increasing beam between valve rod and flap; When the refluence non-return, reduce of the impact of the inertia of valve rod, effectively prevent the fracture of valve rod simultaneously flap.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the structural representation of valve body of the present invention and flow-guiding valve;
Schematic representation when accompanying drawing 3 is opened for flap assembly of the present invention;
Schematic representation when accompanying drawing 4 is closed for flap assembly of the present invention.
Wherein: 1, valve body; 10, deflector; 2, linear bearing; 3, spring seat; 4, valve seat; 5, flap; 6, valve rod; 7, beam.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Like Fig. 1,3, a kind of DRV shown in 4, comprise valve body 1, be arranged on valve body 1 inner valve seat 4, flap 5, valve rod 6, deflector 10 and spring seat 3.
Wherein: flap 5 is connected with valve rod 6; Valve rod 6 passes through bearings on deflector 10; Flap 5 closely contacts with valve seat 4 under the effect on the spring seat 3 mutually; Between flap and valve rod, be provided with beam 7, when the water conservancy diversion non-return, can reduce of the impact of valve rod 6 flaps 5 inertia, effectively prevent valve rod 6 fractures flap.
In addition, in the present embodiment, valve body 1 and deflector 10 are through casting integrated moulding, and be as shown in Figure 2.Like this; Can guarantee the passage molded lines of flow chamber; Reduce conventional construction because of independent valve body 1, deflector 10 are processed, assembled the cumulative departure that produces, effectively guaranteed the design usability of product, also effectively increased the intensity and the rigidity of total simultaneously.
In addition, bearing is selected linear bearing 2 for use, and linear bearing 2 also has the automatic cleaning action to valve rod 6 when guaranteeing valve rod 6 motion guides.Flap 5, valve rod 6 are under water impact; In the process that flap 5 is opened or closed; No matter be that valve rod 6 is along the bearing straight line motion or rotatablely move; The tooth bar of linear bearing 2 and groove can clean the incrustation scale or the rubbish of deposition on the valve rod 6, guarantee the cleaning between valve rod 6 and linear bearing 2 matching gaps, thereby guarantee the no jam of motion assembly.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
