Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
A kind of water hammer-resistant composite exhaust valve as shown in Figure 2, including valve body 1, the flap group that is arranged on inside valve body 1
Part, the bonnet 2 for being arranged on the top of valve body 1, exhaust outlet is offered on bonnet 2.Wherein：Flap component includes floating body 30, is arranged on
Baffle plate 4 is provided with main valve clack 31 on floating body 30, valve body 1.Additionally, being provided with valve seat 6 on valve body 1, valve is provided with valve seat 6
Seat trim ring 7.When air bleeding valve is normally carried out exhaust, floating body 30, main valve clack 31 are supported on baffle plate 4 by Action of Gravity Field；Work as entrance
The fluid of valve body 1 floats floating body 30, main valve clack 31, then air bleeding valve capacity is gradually reduced, until floating up to exhaust valve close
Close.
The circumferential water hammer-resistant support 50 for enclosing, the water hammer-resistant being horizontally set in water hammer-resistant support 50 are provided with bonnet 2
Choke baffle plate 51, the air-flow that formation is connected with exhaust outlet between water hammer-resistant support 50 and the both ends of water hammer-resistant choke baffle plate 51
Passage 52, water hammer-resistant choke baffle plate 51 can in the vertical direction movement increase or reduce gas channel 52 openings of sizes.Tool
Body is：Water hammer-resistant support 50 is connected with each other by screw with valve seat trim ring 7, valve body 1；Water hammer-resistant choke baffle plate 51 is by elasticity
Part, such as spring 8 are connected on bonnet 2.
In the present embodiment：The bottom of water hammer-resistant support 50 has a lower gas port 500, and the top of water hammer-resistant support 50 has upper
Gas port 501, the aperture area of the aperture area more than upper gas port 501 of lower gas port 500；And the aperture area of upper gas port 501 is more than
The area of water hammer-resistant choke baffle plate 51.
Air bleeding valve is provided for limitation water hammer-resistant choke baffle plate 51 and moves up the upper limit part of position, limitation water hammer-resistant
Choke baffle plate 51 moves down the lower limit part 90 of position.Wherein, upper limit part is connected on bonnet 1, using bolt 91
With the combination of nut 92.When moved on water hammer-resistant choke baffle plate 51 be in contact with bolt 91 and nut 92 when, water hammer-resistant choke gear
Plate 51 is located at upper gas port 501；Lower limit part 90 is arranged in water hammer-resistant support 50, and water hammer-resistant choke baffle plate 51 is normally being weighed
When being in contact with lower limit part 90 under power effect, water hammer-resistant choke baffle plate 51 is located in water hammer-resistant support 50.
In normal exhaust operation：When low flow velocity air comes, water hammer-resistant support 50 and water hammer-resistant choke gear can be passed through
Gas channel 52 between plate 51；When air velocity is too fast, pressure differential is formed about 51 in water hammer-resistant choke baffle plate and promotes anti-
The opening of gas channel 52 is moved on water hammer choke baffle plate 51 and reduces limitation exhaust velocity, exhaust velocity slows down the pass for making main valve clack 31
Closing speed and slowing down makes water hammer not produce.Due to the area of the aperture area more than water hammer-resistant choke baffle plate 51 of upper gas port 501, even if
It is to move to be offseted in upper limit part on water hammer-resistant choke baffle plate 51, because the aperture area of upper gas port 501 hinders more than water hammer-resistant
The area of gas baffle plate 51, still there is gap between upper gas port 501 and water hammer-resistant choke baffle plate 51 can be passed through with supplied gas.
Above-described embodiment only to illustrate technology design of the present utility model and feature, technique is familiar with its object is to allow
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover protection domain of the present utility model it
It is interior.
