Abstract
The utility model discloses a decompression valve for a water seal device. The decompression valve for the water seal device comprises a valve body, a valve rod, a spring and a valve seat. The valve body is fixed on the valve seat. A decompression channel is arranged in the valve body. The valve rod is arranged in the decompression channel of the valve body. The spring is connected with the valve rod in a sleeved mode. A wear resistant layer is arranged on the surface of the valve rod. A valve clack is arranged at the lower end of the valve rod. The valve clack is reverse-circular-truncated-cone-shaped. A seal rubber pad is arranged on a connection between the valve body and the valve seat. A circular-truncated-cone-shaped through hole is formed in the seal rubber pad and is matched with the bottom of the valve clack. Vent holes are formed in the valve body. A valve cover is arranged on the upper portion of the valve body and is connected with the valve body in a threaded mode. The upper end of the valve rod penetrates through a center hole of the valve cover, and is matched with the valve cover in a sliding mode. The decompression valve for the water seal device is simple in structure and reasonable in design. Due to the fact that a seal mode under the action of the spring is adopted, the decompression valve automatically returns to normal after decompression, the water seal device which is provided with the decompression valve and other containers are enabled to be capable of continuously working, and use is convenient.
Description
Technical field
The utility model relates to a kind of Decompression valves, particularly a kind of water seal arrangement Decompression valves.
Background technique
Decompression valves on existing water seal arrangement mainly is made of flake aluminum or other thin slices, after air pressure value of overstepping the extreme limit in water seal arrangement, gas breaks through thin slice and releases, air pressure inside reduces, reach the purpose of pressure release, but thin slice is broken during pressure release, needs after pressure release again to change just can work on, operate loaded down with trivial detailsly, affect working efficiency.
Summary of the invention
It is a kind of easy to use that the purpose of this utility model just is to provide, long service life, and the water seal arrangement Decompression valves of high working efficiency can effectively solve the problem of above-mentioned existence.
to achieve these goals, the technical solution adopted in the utility model is such: water seal arrangement Decompression valves of the present utility model, comprise valve body, valve rod, spring and valve seat, valve body is fixed on valve seat, be provided with pressure release passage in valve body, valve rod is arranged in the pressure release passage of valve body, spring housing is connected on valve rod, described stem surface is provided with wearing layer, the lower end of valve rod is provided with flap, flap is reverse frustoconic, described valve body and valve seat joint are provided with seal rubber pad, seal rubber pad is provided with the frustoconic shape through hole that is complementary bottom flap, valve body is provided with vent, valve body top is provided with valve gap, valve gap is connected with valve body screw thread, the center hole of valve gap is passed in described valve rod upper end, and valve gap is slidably matched.
As preferably, described wearing layer is the vulcanite layer.
As preferably, described through hole is 4, is arranged on the valve body middle part, and evenly distributes.
As preferably, described valve gap inwall is provided with seal ring.
Compared with prior art, the utility model has the advantage of: the utility model is simple in structure, reasonable in design, adopt the sealing means under spring action, automatically return to normal after the Decompression valves pressure release, make water seal arrangement that Decompression valves is installed and other container can continuous operation, via design on flap and seal rubber pad is reverse frustoconic, makes its sealing more reliable, and valve rod is provided with wearing layer, make valve rod wear-resistant, it can prevent air corrosion, extends its working life, and valve gap is provided with seal ring, prevent that fluid from overflowing from valve gap, be inconvenient to clear up.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, valve body; 2, valve rod; 3, valve seat; 4, valve gap; 5, flap; 6, spring; 7, wearing layer; 8, pressure release passage; 9, seal rubber pad; 10, vent; 11, seal ring.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
referring to Fig. 1, water seal arrangement Decompression valves of the present utility model, comprise valve body 1, valve rod 2, spring 6 and valve seat 3, valve body 1 is fixed on valve seat 3, be provided with pressure release passage 8 in valve body 1, valve rod 2 is arranged in the pressure release passage 8 of valve body 1, spring 6 is socketed on valve rod 2, described valve rod 2 surfaces are provided with wearing layer 7, the lower end of valve rod 2 is provided with flap 5, flap 5 is reverse frustoconic, described valve body 1 is provided with seal rubber pad 9 with valve seat 3 joints, seal rubber pad 9 is provided with the frustoconic shape through hole that is complementary with flap 5 bottoms, valve body 1 is provided with vent 10, valve body 1 top is provided with valve gap 4, valve gap 4 is threaded with valve body 1, the center hole of valve gap 4 is passed in described valve rod 2 upper ends, and valve gap 4 is slidably matched, described wearing layer 7 is the vulcanite layer, described through hole is 4, be arranged on valve body 1 middle part, and evenly distribute, described valve gap 4 inwalls are provided with seal ring 11.
under normality, flap 5 lower end surfaces coordinate with the through hole of seal rubber pad 9, sealing pressure release passage 8, flap 5 is frustoconic shape with through hole, sealing effect is good, when hydrodynamic pressure value of overstepping the extreme limit that pressure release passage 8 suction ports go out, will promote flap 5 overcomes spring 6 elastic force and moves up, fluid passes the gap between flap 5 and seal rubber pad 9, release through vent 10, hydrodynamic pressure in container descends, when hydrodynamic pressure during lower than limiting value, flap 5 is under the elastic force effect of spring 6, move down and be pressed on sealing gasket, Decompression valves recovers sealing state, make water seal arrangement or other containers that Decompression valves is installed, pipeline can work on.Owing to adopting the spring 6 lower sealing means of effect, automatically return to normal after the Decompression valves pressure release, make water seal arrangement that Decompression valves is installed and other container can continuous operation, easy to use, high working efficiency; The surface of valve rod 2 is provided with wearing layer 7, and is not fragile when valve rod 2 is slided on valve gap 4, and can prevent airborne etchant gas corrosion, extended its working life, valve gap 4 is provided with seal ring 11, prevents that fluid from overflowing from valve gap 4, be inconvenient to clear up, be fit to promote the use of.
