Abstract
The utility model relates to an angle type check valve with good sealing property and stable performance, which comprises a valve body, a valve cover, a valve clack, a valve seat and a spring. The top of the valve body is connected with the valve cover. The valve clack is arranged in a cavity consists of the valve body and the valve cover. The valve seat is arranged in the valve body. The spring is arranged on the back surface of the valve clack. The angle type check valve also comprises at least four guide rails which are arranged around the valve clack and are fixed in the valve body. The top of the valve clack is positioned by the valve cover while the bottom of the valve clack is straightened by the guide rails. The valve clack can freely move between the guide rails. Compared with the prior art, the angle type check valve provided by the utility model has the advantages of wide application range, stable action, good sealing property, convenient use, etc.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of angie type safety check of good airproof performance stable performance.
Background technique
Safety check has another name called check valve, one-way valve or one-way valve, is used for preventing on the pressure piping medium counter flow usefulness; Generally be used in the delivery side of pump place, when termination of pumping, can flow backwards to prevent medium by automatic-closing valve.
At present common safety check has three kinds of Lift check valve, Swing check valve and Vertical Lift Check Valves, and the different defective of respectively depositing again of their structures can only horizontal (level) installation and can not vertically install and use like rise-fall type and Swing check valve.Vertical Lift Check Valves can only vertically be installed and can not level install and use.Produce the various in style of safety check thus, give and to design, to select for use, purchase and use brings inconvenience.
Summary of the invention
The purpose of the utility model be exactly provide a kind of in order to overcome the defective that above-mentioned existing technology exists and use extensively, the angie type safety check of stable action, good airproof performance stable performance that airtight performance is good, easy to use.
The purpose of the utility model can realize through following technological scheme: a kind of angie type safety check of good airproof performance stable performance, comprise valve body, valve gap, flap, valve seat and spring, and described valve body top connects valve gap; Described flap is arranged in the cavity of valve body and valve gap composition, is provided with valve seat in the valve body, and described spring is arranged on the flap back side; It is characterized in that also comprise at least four guide rails, each guide rail is scattered in around the flap; And be fixed in the valve body; Described flap top is located by valve gap, and the bottom is set upright by guide rail, and flap is free movable between guide rail.
Described guide rail and valve body integral type are provided with.
Described valve body is connected through bolt with valve gap.
Described flap is T type shape structure, and its underpart is hemisphere, and top is the cylinder bodily form, and the flap bottom is free movable between guide rail, and bonnet lower is inserted on flap top, through valve gap it is positioned.
Compared with prior art, the utlity model has following advantage:
One, using scope is wider: this novel structure that the flap of this valve is set upright by guide rail, and valve can be installed and used in any position, broken the narrow limitation that conventional safety check receives the mounting point restriction, enlarged using scope;
Two, stable action, impact little: flap is owing to the centralizing function of valve gap and guide rail, and valve is shockproof, noise free when operation, has reduced the impact to valve base sealing,
Three, airtight performance is good: under the effect of spring, and flap quick closedown, long service life.
Four, easy to use: installation, maintenance and the replacing of the more convenient valve of right-angle type structure.
Description of drawings

Fig. 2 is the utility model safety check opening state structural representation;
Fig. 3 is the A-A view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
Shown in Fig. 1-3; A kind of angie type safety check of good airproof performance stable performance; Comprise valve body 1, valve seat 2, flap 3, spring 4, valve gap 5, guide rail 6, described valve body 1 top, only need be laid down bolt, take away valve gap by the seal ring sealing through bolted bonnet (BB) 5; Need not any instrument and just can take out spool, can be implemented in the line maintenance.Be provided with valve seat 2 in the valve body 1, during valve closing, flap 3 is positioned on the valve seat 2.
Described flap 3 is arranged in the cavity of valve body 1 and valve gap 5 compositions, and described spring 4 is arranged on flap 2 back sides with auxiliary flap quick closedown.
Also comprise at least four guide rails 6 (the present embodiment middle guide is provided with 4), each guide rail is scattered in around the flap 3, and is fixed in the valve body 1; Described flap 3 is T type shape structure; Its underpart is hemisphere, and top is the cylinder bodily form, and flap 3 bottoms are set upright by guide rail 6; Flap 3 is up and down on 6 on guide rail, and never deviation can be not stuck.So this valve can level be installed and used to the left or to the right, also can install and use up or down, southeastward any one direction of northwest or any one angle are installed and used after lying low.Valve gap 5 bottoms are inserted on flap 3 tops, through valve gap 5 it are positioned.
The curved design of the stream of arc line type makes medium along its gravity flow, and resistance is little, avoids medium 90 degree right angles zig zag, produces whirlpool and build-up of pressure loss.
When acting on flap 3 bottoms from the medium in the pipeline, when pressure during greater than flap 3 deadweight and spring 4 active forces and back pressure, flap 3 disengaging valve seats 2 valves are opened (seeing schematic representation 2) automatically.Otherwise, when back pressure during greater than malleation, flap 3 by guide rail 6 and valve gap 5 set upright and the effect of spring 4 under, flap 3 and valve seat 2 momentary engagement, valve is closed (seeing schematic representation 1) automatically.
Claims (4)
1. the angie type safety check of a good airproof performance stable performance comprises valve body, valve gap, flap, valve seat and spring, and described valve body top connects valve gap; Described flap is arranged in the cavity of valve body and valve gap composition, is provided with valve seat in the valve body, and described spring is arranged on the flap back side; It is characterized in that also comprise at least four guide rails, each guide rail is scattered in around the flap; And be fixed in the valve body, described flap top is located by valve gap.
