Abstract
The utility model relates to a suspension needle type automatic washing exhausting valve, which comprises a shell. An exhaust hole and an intake hole are arranged on the shell. A needle body tapered seat is connected with the exhaust hole. A floating ball is arranged in the shell. The upper end of the floating ball is fixed to a needle body valve rod matched with the needle body tapered seat. The suspension needle type automatic washing exhausting valve is characterized in that the needle body valve rod is also fixed to the lower end of the floating ball; a supporting axle seat is arranged at a bottom end in the shell, and is matched with the needle body valve rod; a plurality of air slots are arranged on a peripheral wall of the floating ball; the intake hole is arranged on one side wall of the shell. The utility model has the advantages of automatic cleaning, flexible and reliable action, long service life, etc.
Description
A kind of suspension needle type that is used for heating system cleans outlet valve automatically.
Existing floating ball type discharge valve is by housing, in the bottom of housing inlet hole is set, and in the upper end exhaust port is set, and ball float is set in housing, and fixing needle shape valve lever on ball float, needle shape valve lever are suspended from the needle body awl seat that is connected with the housing exhaust port and go up and form.The deficiency of this outlet valve is, because inlet hole is in the bottom of housing, ball float and the needle shape valve lever that is fixed on the ball float can only move vertically, and needle shape valve lever can not get cleaning with the dirt at the needle body seat place of matching, and influences the using effect of valve; Also owing to be suspended from the needle body awl seat with the fixing needle shape valve lever of ball float, a needle shape valve lever only end has supporting, and needle shape valve lever is subjected to the effect of lateral force, and the cooperation place of needle shape valve lever and needle body awl is easy to wear, and working life is low.
The purpose of this utility model is to provide a kind of ball float and needle shape valve lever to be combined into one, the needle shape valve lever two ends have supporting, and radial location, ball float and needle shape valve lever can rotate, needle shape valve lever can clean automatically with the needle body awl seat place of matching, flexible movements are reliable, and the suspension type of long service life cleans outlet valve automatically.
The purpose of this utility model is realized by following technological scheme: a kind of suspension needle type cleans outlet valve automatically, it comprises the housing 1 that is connected, 2, exhaust port 10 is set on housing 1, inlet hole 14 is set on housing 2, the needle body awl seat 9 of band exhaust port 15 is connected with exhaust port 10, at housing 1, ball float 8 is set in 2, the upper end of ball float 8 is fixed with and needle body awl seat 9 needle shape valve levers that match 6, it is characterized in that: needle shape valve lever 6 is also fixed with the lower end of ball float 8, bottom in housing 2 is provided with bearing axle seat 5, bearing axle seat 5 matches with needle shape valve lever 6, is provided with several wind grooves 4 on ball float 8 perisporiums, and inlet hole 14 is arranged on the sidewall of housing 2.
Said inlet hole 14 is a slope hole.
Suspension needle type of the present utility model cleans outlet valve automatically and compares with existing floating ball type discharge valve, because the utility model adopts the upper end of needle shape valve lever by the supporting of needle body awl seat, the lower end is by the structure of the two supports of bearing axle seat supporting, make the needle shape valve lever radial location, also owing on the perisporium of ball float, be provided with several wind grooves, inlet hole is arranged on the sidewall of housing, and be obliquely installed, the gas that is entered in the housing by inlet hole acts on the wind groove, the needle shape valve lever that makes ball float and be fixed on the ball float rotates, can realize the cleaning of needle shape valve lever and needle body awl seat, avoid matching part to have dirt to produce, needle shape valve lever and needle body awl seat matching part are not easy to wear, flexible movements are reliable, advantages such as the long service life of valve.
The utility model is described in further detail to utilize embodiment shown in the drawings below.
Fig. 1 cleans the exhaust structure schematic representation automatically for suspension needle type.
Fig. 2 is an A-A cross-sectional schematic among Fig. 1.
With reference to Fig. 1, housing 1, place sealing gasket 3 between 2 and use bolt, be connected with bearing axle seat 5 in the lower end of housing 2, housing 1, needle shape valve lever 6 usefulness nuts 7 in 2 are fixed in the two ends of ball float 8, on the perisporium of ball float 8, be provided with several wind grooves 4, needle shape valve lever 6 lower end endoporus match with the axle of bearing axle seat 5, match with needle body awl seat 9 in needle shape valve lever 6 upper ends, needle body awl seat 9 can two systems be done, needle body awl seat 9 is connected with the exhaust port 10 of housing 1, the lower end side of needle body awl seat 9 is to exhaust hole 15 is arranged, exhaust joint 11 is connected with the exhaust port 10 of housing 1, and the upper end is connected with gland 12, and exhaust joint 11 is provided with exhaust port 16, be provided with blowdown plug 13 in the bottom of housing 2, on the sidewall of the lower end of housing 2, be provided with inlet hole 4.
With reference to Fig. 2, the inlet hole 14 that is provided with on housing 2 lower end sidewalls is slope hole.
During use, gas enters in the housing 1,2 from the inlet hole 14 of valve, the wind groove 4 of ball float 8 is subjected to upward flow lateral impact power and rotates, the needle shape valve lever of fixing with ball float 86 rotates in needle body awl seat 9, can clean the dirt of needle shape valve lever 6 and needle body awl seat 9 automatically, along with gas discharges, liquid rises thereupon, the buoyancy of ball float 8 liquid bodies drives needle shape valve lever 6 and rises, the ball float 8 that rises is stopped operating by the impact of air-flow no longer, make it needle shape valve lever 6 and needle body awl seat 9 taperings and contact and valve cuts out, stop exhaust.
