Abstract
The utility model relates to a combined explosion wave proof check valve, composed of a valve body, a valve seat, a valve plate, a decompressor, an air chamber, a shell body, a support bracket, a rubber ball, etc. The water inlet end of the valve is in an explosion wave proof structure and the water outlet end is in a global check device structure. The outer part of a supporting spring adopts a waterproof sealing structure which can effectively prevent medium from corroding the spring and prolong the service life. The valve has the function of explosion wave proof and also has the function for preventing the medium from back flowing. With two usages, the valve is especially suitable for being used in the feed piping in the defense engineering.
Description
The utility model relates to a kind of anti-deflagration wave check valve of combined type that will prevent that deflagration wave valve and ball-type check device are combined.
By the anti-deflagration wave check valve that is loaded in the shielding engineering feedwater piping; it mainly acts on: when there is strong explosion time the outside; produce shock wave; by pumping plant, pond, when pipeline imports valve into; this valve can play the effect of " retaining ripple ", " wave absorption ", thereby can protect shielding engineering internal staff installation security effectively.
Existing anti-deflagration wave valve, because the support spring of its valve plate is immersed in the medium throughout the year, the working life of preventing the deflagration wave valve is shortened in corrosion easily.All there is not check function at existing anti-deflagration wave valve in addition, generally all need be in the pipeline by the loaded check valve door, in case medium back flow.
The purpose of this utility model so is to provide a kind of anti-deflagration wave safety check of combined type explosion-proof wave energy and check function, long service life that integrates.
Below in conjunction with accompanying drawing technical solution of the present utility model is described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is I among Fig. 1-I position sectional view.
Fig. 3 is II among Fig. 1-II position sectional view.
The sequence number of marking is expressed as follows respectively in the accompanying drawing:
1, flange; 2, valve body; 3, seal ring; 4, air chamber; 5, decompressor; 6, stuffing box packing; 7, Boilor check valve seat; 8, housing; 9, support; 10, valve plate; 11, sealing gasket; 12, sealed pipe; 13, support spring; 14, explosion-proof valve seat; 15, stuffing box gland; 16, sealing seat; 17, gland nut; 18, adjusting nut, 19, asbestos packing; 20, glueballs.
By valve body, valve seat, valve plate, decompressor, air chamber, support spring, shell The Combined explosion wave proof check valve door that body, support, glueballs etc. form, this valve advances Water end (W.E.) is anti-explosion valve structure, and the water side is the ball-type check device; Its support spring 13 Being sealed in sealing shroud 15 inside is connected with sealed tube 12 and seal receptacle 16; Sealed tube 12 are connected with valve plate 10; Sealing shroud 15 is connected with sealed tube 12 and seal receptacle 16; Seal receptacle 16 is connected with valve body 2; Housing 8 is connected with valve body 2; Support 9 and shell Body 8 is connected, and glueballs 20 is positioned at support 9.
In order to make support spring be subjected to good sealing, at seal receptacle 16 and compression spiral shell Be provided with airtight and watertight padding 6 between female 17, between valve plate 10 and sealed tube 12, be provided with close Packing 11 and sealing ring 3.
The stuffing box gland 15 general rubber materials that adopt are made.
Regulate valve plate by adjusting nut 18 during use and explosion-proof valve seat 14 maintains a certain distance, make medium reach certain flow.When there is powerful explosion time the outside, the shock wave that produces is by pumping plant, pond, when pipeline imports valve into, the valve plate forefront pressure increases suddenly, makes valve plate front and back pressure reduction surpass spring tension, and spring is compressed, valve plate is closed,) shock wave is blocked in beyond the valve plate, the decompressor that is contained in air chamber plays " wave absorption ", " decompression " effect, and the back end pressure is arranged to air chamber, reduce valve rear end pressure, be beneficial to valve plate and close.After shock wave disappeared, valve plate was opened rapidly by the supporting of spring, and what this moment, glueballs was subjected to water hammer is pushed to Boilor check valve seat 7, makes the medium non-return, has also eliminated the water hammer of pipeline simultaneously.
This combined type is prevented the advantage of deflagration wave check valve, just is to have adopted the composite structure of anti-deflagration wave valve and ball-type check device, and a valve dual-purpose, particularly support spring is subjected to strict sealing, avoids contacting with medium, and prolong its working life greatly.
Embodiment:
DN80mm, nominal pressure 0.5MPa
Valve body 2, housing 8 adopt seamless steel pipe, steel plate welding to make.Valve plate 10, explosion-proof valve seat 14, gland nut 17, adjusting nut 18 adopt stainless steel to make.Glueballs 20 inside are steel core, and outpacking rubber is made.Decompressor 5 and air chamber 4 are same as existing anti-deflagration wave valve mechanism.Spring 13 is made for Spring Steel Wire.Sealing gasket 11, seal ring 3, stuffing box gland 15 are rubber and make.Sealed pipe 12, sealing seat 16 are steel.Stuffing box packing 6 is asbestos.
