Abstract

The utility model provides a novel exhaust valve, which is long in service life and comprises an exhaust valve cover, a water outlet valve cover and a ball cover, wherein a fluid inlet is formed in the lower end of an exhaust valve body; the upper end of a floater is connected with a push rod; the upper end of the push rod is connected with a lifting ring; the lifting ring is connected with an inner spacer sleeve; the inner spacer sleeve is mounted on the inner side of the fluid inlet; an exhaust hole is horizontally formed in the exhaust valve body and in a position close to the upper end; the exhaust valve cover is screwed to the exhaust hole; the ball valve is arranged at the upper end of the exhaust valve; a water outlet is formed in the upper end of the ball valve; the water outlet valve cover is screwed to the water outlet. According to the novel exhaust valve, the ball valve and the water outlet are added at the upper end of the exhaust hole, and the water outlet is opened or closed by controlling the ball valve to discharge cool water, so that the situation that the exhaust valve is blocked by impurities in the water when being used for preventing the water is avoided, the service life of the exhaust valve is prolonged, a water outlet valve is not required to be additionally added, and the mounting cost is reduced.

Description

A kind of Novel vent valve

Technical field

The utility model relates to pipeline air exhaust water field, relates in particular to a kind of Novel vent valve.

Background technique

Outlet valve is requisite auxiliary element in pipe-line system, be generally used for independent heating system, central heating system, heating boiler, central air-conditioner, in the exhaust duct such as floor heating and solar heating system, being arranged on commanding height or elbow etc. locates, be used for getting rid of gas unnecessary in pipeline, improve pipeline utilization efficiency, reduce energy consumption, in water-system pipeline, pipeline is owing to being subject to for a long time the corrosive action of water, on inner-walls of duct, generate one deck rust deposite, in water heating system, except needs are discharged gas, also need the cold water that is trapped in pipe end to discharge, the relief opening of outlet valve is generally all smaller, if use outlet valve draining, the impurity in water very easily accumulates in exhaust ports and stops up outlet valve, cause outlet valve to lose efficacy, generally all need to add in addition to put valve, so just make the installation of hot-water supply system complicated, installation and the maintenance cost of whole system are more increased.

Summary of the invention

According to above technical problem, the utility model provides a kind of good exhaust effect, the Novel vent valve of long service life, comprise outlet valve body, relief opening, exhaust valve cap, fluid inlet, float, push rod, lifting ring, inner spacer sleeve, it is characterized in that: also comprise drain opening, draining valve gap, ball valve, the lower end of described outlet valve body is fluid inlet, the upper end of described float is connected with push rod, the upper end of described push rod is connected with lifting ring, described lifting ring is connected with inner spacer sleeve, described inner spacer sleeve is arranged on the inner side of fluid inlet, position near upper end on described outlet valve body is horizontally disposed with relief opening, described exhaust valve cap is screwed to relief opening, the upper end of described outlet valve is provided with ball valve, the upper end of described ball valve is drain opening, described draining valve gap is screwed to drain opening.

The beneficial effects of the utility model are: the utility model improves on original outlet valve, increased ball valve in the upper end of relief opening, and the upper end at ball valve has increased drain opening, ball valve is combined dexterously with outlet valve, open or close drain opening by control ball valve and carry out the discharge of cold water, impurity while having avoided using outlet valve waterproof in water stops up the situation of outlet valve, thereby extend the working life of outlet valve, do not need to add in addition and put water discharging valve and carry out draining, saved the installation cost of system yet.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

Embodiment

Shown in Fig. 1, the utility model is further described:

As Fig. 1, relief opening-1, exhaust valve cap-2, fluid inlet-3, float-4, push rod-5, lifting ring-6, inner spacer sleeve-7, drain opening-8, draining valve gap-9, ball valve-10;

Embodiment 1

The utility model comprises relief opening 1, exhaust valve cap 2, fluid inlet 3, float 4, push rod 5, lifting ring 6, inner spacer sleeve 7, drain opening 8, draining valve gap 9, ball valve 10, the lower end of outlet valve body is fluid inlet 3, position level near upper end on outlet valve body is provided with relief opening 1, in the upper end of outlet valve, ball valve 10 is set, in the upper end of ball valve 10, drain opening 8 is set, when installation, first the upper end of float 4 is connected with push rod 5, the upper end of push rod 5 is connected with lifting ring 6, lifting ring 6 is connected with inner spacer sleeve 7, then inner spacer sleeve 7 is arranged on to the inner side of fluid inlet 3, finally exhaust valve cap 2 is screwed to relief opening 1, draining valve gap 9 is screwed to drain opening 8.

Embodiment 2

When exhaust, air-flow enters outlet valve body from fluid inlet 3, float 4 moves up along with the rising of water level in pipeline, promotes lifting ring 6 to move up by push rod 5, and inner spacer sleeve 7 is also moved up, thereby relief opening is dwindled gradually, air-flow backs down exhaust valve cap 2, discharges, when in pipeline during without gas by relief opening 1, float 4 is in extreme higher position, and now inner spacer sleeve 7 blocks relief opening 1 completely; Gas is drained while also needing draining, turn on exhaust valve cap 2, regulate the aperture of ball valve 10 to carry out draining.
