Abstract
The utility model discloses a kind of tubule road air bleeding valve, including valve body, the valve body is divided into upper shell and lower house, it is characterized in that the external screw thread of upper shell bottom and the internal thread on lower house top are spirally connected, lower house lower weld has valve seat, upper casing body sidewall top is connected with blast pipe, and blast pipe is extend into valve body, and the face for the blast pipe mouth of pipe extending into valve body is scarf；Valve inner, which is additionally provided with floating block and diaphragm seal, floating block, is provided with inclined-plane corresponding with above-mentioned scarf, and diaphragm seal one end is located at blast pipe lower end, and other end connection floating block upper end, floating block floating drives diaphragm seal to seal the blast pipe mouth of pipe.The utility model can be realized and be vented repeatedly automatically on the premise of tubule road air bleeding valve air-tightness is ensured, it is to avoid floating ball type discharge valve is because of the effect of gas support, and ball float blocks exhaust outlet and can not be vented in time.
Description
Technical field
The utility model is related to a kind of exhaust apparatus, and in particular to a kind of tubule road air bleeding valve.
Background technology
In recent years, aqueduct exhausting problem is increasingly paid attention to by water hammer expert and hydraulician, in pipeline
Gas is usually present in top or the uplift sector of pipeline in the form of an airbag.There is air bag in pipeline, gently then reduce pipeline
Water delivery section face reduces water delivery flow, wastes electric energy, heavy then initiation water flow impulsion pipeline.For the thinner water distribution pipeline of pipeline, adopt
With floating ball type discharge valve, but part floating ball type discharge valve first paragraph gas or can be high during first air bag only in discharge line
Speed exhaust, but after drained first paragraph gas, ball float moves up the exhaust outlet for blocking body top, then when carrying out gas, ball float is because of gas
Support effect is difficult to open exhaust so that exhaust is not in time；In order to overcome this difficult, generally using the method for increase ball float, but
It is that the volume and weight of such ball float can all increase, the volume of air bleeding valve can also increase, except being difficult to meet the installation of tubule road
It is required that outer, the sealing of air bleeding valve itself is also difficult to be protected, thus this air bleeding valve is insecure.
The content of the invention
Problem to be solved in the utility model, is that common tubule road exhaust valve exhaust is not prompt enough, while air-tightness
It is difficult to be protected.
The utility model provides a kind of tubule road air bleeding valve, including valve body, and the valve body is divided into upper shell and lower house, its
It is characterised by that the external screw thread and the internal thread on lower house top of upper shell bottom are spirally connected, lower house lower weld has valve seat, upper casing
Body sidewall top is connected with blast pipe, and blast pipe is extend into valve body, and the face for the blast pipe mouth of pipe extending into valve body is beveling
Face；Valve inner, which is additionally provided with floating block and diaphragm seal, floating block, is provided with inclined-plane corresponding with above-mentioned scarf, diaphragm seal one end position
In blast pipe lower end, other end connection floating block upper end, floating block, which floats, drives diaphragm seal to seal the blast pipe mouth of pipe.After mouth of pipe closing,
It is not completely closed between body top and floating block, leave gap.When gas enters air bleeding valve, water level decreasing, when air pressure is excessive,
Due to the effect of gas support, ball float is difficult to continue to block exhaust outlet with water level decreasing, and blast pipe is located at valve body by the utility model
Side wall, gas can reach case top along the gap at floating block and housing sidewall and top, form top-down air pressure, and with
Air pressure under floating block is identical, due to Action of Gravity Field, and floating block declines, so that drive connected sealing surface to open, gas discharge.
With the discharge of gas, water level rises, and floating block is moved up with water level, so as to drive sealing surface to seal up exhaust outlet；So it can be achieved
It is vented repeatedly.
Because diaphragm seal closes unlatching repeatedly, and in a humid environment, so easily it is damaged for a long time, so as to influence row
The sealing of air valve, it is impossible to ensure that the permanent of air bleeding valve uses.Further, the utility model also includes card in enclosure interior
Bar, card article detachable connection lower casing body sidewall, card article upper-end bent encloses with blast pipe lower end and blocks diaphragm seal.Such situation
Under, upper and lower casing is outwarded winding, pulling down card article can change to diaphragm seal, conveniently save trouble, while being also beneficial to the air bleeding valve
Maintenance.
Compared with prior art, the beneficial effects of the utility model are：Before tubule road air bleeding valve air-tightness is ensured
Put, can realize and be vented repeatedly automatically, it is to avoid floating ball type discharge valve is acted on because of gas support, ball float block exhaust outlet and can not and
When be vented.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Marked in figure：
10. upper shell, 11. lower houses, 20. blast pipes, 21. valve seats, 30. floating blocks, 31. diaphragm seals, 32. card articles.
Embodiment
In order to more fully understand the utility model, the utility model is further explained with reference to the present embodiment
It is bright.
The utility model provides a kind of tubule road air bleeding valve, including valve body, and the valve body is divided into upper shell 10 and lower house
11, it is characterised in that the external screw thread of upper shell bottom and the internal thread on lower house top are spirally connected, and lower house lower weld has valve seat
21, upper casing body sidewall top is connected with blast pipe 20, and blast pipe 20 is extend into valve body, the blast pipe mouth of pipe extending into valve body
Face be scarf；Valve inner be additionally provided with floating block 30 and diaphragm seal 31, floating block 30 be provided with it is corresponding with above-mentioned scarf
Inclined-plane；Valve inner is also included under card article 32, card article detachable connection lower casing body sidewall, the upper-end bent of card article 32 and blast pipe
End, which is enclosed, blocks diaphragm seal 31, other end connection floating block 30 upper end, and floating block, which floats, drives diaphragm seal to seal the blast pipe mouth of pipe, now
Gap is left between upper shell and floating block.
When gas is declined by entering housing, liquid level, floating block declines with liquid level, and valve is opened, and gas is arranged from blast pipe
Go out；Rise with the discharge liquid level of gas, now ball float rises, drive diaphragm seal to close the blast pipe of valve；This action will
With liquid increase and reduce repetition.
Above-described embodiment is only preferred embodiment, not to the restriction of embodiment.For the common of art
For technical staff, it can also make other changes in different forms on the basis of the above description.Fan Yiben is practical
Equivalence changes and modification that the content of new claim is made, all should be used as technology category of the present utility model.
