Abstract
The utility model provides a combined type sewage exhaust valve, and relates to the field of water supply and drainage valves. The combined type sewage exhaust valve comprises a valve body, a valve deck, an exhaust cap, a connecting rod, a floating ball and a piston mechanism. The piston mechanism comprises a piston main shaft which penetrates through a guide sleeve, a washer arranged below the piston main shaft, a piston arranged below the valve deck and on the piston main shaft, and a top plug arranged on the valve deck. The combined type sewage exhaust valve is characterized in that a spring is horizontally arranged on the piston main shaft, one end of the spring is connected with the piston main shaft, the other end of the spring is provided with a sealing piece, and the sealing piece is pushed upwards by the spring on the inner wall of an exhaust pipeline of the valve deck. The combined type sewage exhaust valve is simple in structure and reasonable in design. The piston and the top plug are in primary seal, the sealing piece and an exhaust vent are in secondary seal, a large number of gaps are formed in the spring, and therefore on the premise that the exhaust effect is not affected, the reliability of the sealing is enhanced, and the leakage phenomenon is reduced.
Description
Technical field:
The utility model relates to the plumbing valve field, relates in particular to a kind of Combined sewage exhaust valve.
Background technique:
Sewage exhaust valve is used for source water transfer line, in order to the air of the ducted assembly of a large amount of eliminatings, promoting water pipe and suction engine utilization efficiency, and in pipe in case when negative pressure occurring, this valve is air amount rapidly, just the facial canal line damages because of negative pressure.
Existing sewage exhaust valve fails effectively to solve the secondary environmental pollution that causes because of the leakage of outlet valve fault, the patent No. is that " the slick and frivolous ball " described in CN201120437638.3 " double-sealing leakage protection sewage exhaust valve " is for spherical, be arranged in exhaust duct, for reaching sealing effect, need " slick and frivolous ball " that certain size is arranged, although played like this effect of sealing, affected air displacement, exhaust effect is not good.
The model utility content:
Technical problem to be solved in the utility model is to overcome the defective of prior art, provides a kind of good sealing effect and exhaust effect good Combined sewage exhaust valve.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of Combined sewage exhaust valve, comprise valve body, valve gap, smoke releasing cap, connecting rod, ball float and piston mechanism, described piston mechanism comprises the spindle piston that passes guide pin bushing, be located at the gasket rings of spindle piston below, be located at the piston on the spindle piston of valve gap below and be located at top plug on valve gap, it is characterized in that: described spindle piston is provided with spring, the spring cross setting, one end connects spindle piston, and the other end is provided with Sealing, Sealing by spring top on valve gap exhaust duct inwall.
Described Sealing is spherical sealing element, and the spherical surface curve can better slip into exhaust port.
Described Sealing is arranged on the below of exhaust port, and Sealing quantity is consistent with exhaust port quantity, and the size of Sealing is greater than exhaust port, and Sealing does not have the effect of sealing less than exhaust port.
The distance of the distance of described Sealing and exhaust port and piston and top plug equates, completes when sealing when piston moves to the top plug, and Sealing withstands on simultaneously and completes secondary seal in exhaust port.
The pole that is provided with supported spring in described spring is connected on spindle piston, and fixing spring avoids the Sealing can not corresponding exhaust port.
The utility model is simple in structure, and is reasonable in design, and piston is once sealing with the top plug, and Sealing and exhaust port are secondary seal, and there are a large amount of gaps in spring part, has increased the reliability of sealing under the effect that does not affect exhaust, reduces leakage phenomenon.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
a kind of Combined sewage exhaust valve as shown in Figure 1, comprise valve body 1, valve gap 2, smoke releasing cap 3, connecting rod 4, ball float 5 and piston mechanism 6, wherein piston mechanism 6 comprises the spindle piston 102 that passes guide pin bushing 101, be located at the gasket rings 103 of spindle piston 102 belows, the top that is located at the piston 104 on valve gap 2 below spindle pistons 102 and is located on valve gap 2 fills in 105, wherein spindle piston 102 is provided with spring 106, spring 106 cross settings, one end connects spindle piston 102, the other end is provided with Sealing 107, the pole 108 that is provided with supported spring 106 in spring 106 is connected on spindle piston 102, wherein Sealing 107 is withstood on valve gap 2 exhaust duct 7 inwalls by spring 106, Sealing 107 is spherical sealing element, Sealing 107 is arranged on the below of exhaust port 8, Sealing 107 quantity are consistent with exhaust port 8 quantity, and the size of Sealing 107 is greater than exhaust port 8, the distance of Sealing 107 and exhaust port 8 equates with the distance of piston 104 and top plug 105.
Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
