Description
Technical field
The present invention relates to a kind of packoff, particularly a kind of valve control water meter actuator packoff.
Background technology
It is the O-ring seal of O shape or rectangle that at present existing actuator adopts the cross section, and the actuator seal box needs the axial compression O-ring seal, because unbalance stress easily causes actuator seal box Deformation of Face Seal.Because actuator seal box Deformation of Face Seal makes the compression discontinuity of O-ring seal, the long-time use easily leaked, and product percent of pass is lower.In the situation that environment for use is had relatively high expectations, especially the environment of the ground well inner product depth of water can't use at all, can't meet the need of market.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, proposes a kind of good seal performance, the valve control water meter actuator packoff that can meet the need of market.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of valve control water meter actuator packoff, comprise water meter actuator seal box and base plate, be characterized in: the outer rim at base plate is provided with locating slot, U-shaped O-ring seal is installed in locating slot, the lower end of water meter actuator seal box is inserted in the U-shaped notch of U-shaped O-ring seal, the groove depth of U-shaped notch is 2.5mm-4mm, the many at least 1mm of thickness of the Thickness Ratio notch inwall of the notch outer wall of U-shaped O-ring seal are provided with V-shaped valley at the top of the notch outer wall of U-shaped O-ring seal.
The technical problem to be solved in the present invention can also be come further realization by the following technical programs, and the outer wall in water meter actuator seal box lower end is provided with the fin that cooperates with the notch outer wall of U-shaped O-ring seal.
The technical problem to be solved in the present invention can also be come further realization by the following technical programs, and the height of described fin is not more than 0.5mm.
The technical problem to be solved in the present invention can also be come further to realize by the following technical programs, is provided with the assembly platoon pore in the locating slot bottom of base plate, is provided with sealing-plug in the assembly platoon pore.
Compared with prior art, the present invention is designed to 2.5mm-4mm with the groove depth of the U-shaped notch of U-shaped O-ring seal, can guarantee the sealing of U-shaped O-ring seal, can guarantee again the machining precision of U-shaped O-ring seal; The thickness of the notch outer wall of U-shaped O-ring seal is set to thickness than the notch inwall and manys at least 1mm, the inside and outside wall of notch of U-shaped O-ring seal and the constant compression amount of base plate two sides have been guaranteed, so that U-shaped O-ring seal is pressed tighter and tighter, improved the reliability of sealing, satisfied the demand in market; Utilization is arranged on the V-shaped valley at U-shaped O-ring seal outer wall top,, U-shaped O-ring seal is compressed to base plate and water meter actuator seal box two sides during in the V-shaped valley inclined-plane in effect of water pressure, has increased sealing force; The fin that utilization cooperates with the notch outer wall of U-shaped O-ring seal on the outer wall of water meter actuator seal box lower end has increased the Local Contraction amount of O-ring seal; Utilization is arranged on the assembly platoon pore of base plate locating slot bottom, when assembling, with unnecessary Bas Discharged, use again sealing-plug the assembly platoon port sealing, form the vacuum chamber of a sealing, suction by vacuum chamber is installed firmly water meter actuator seal box, is difficult for throwing off.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of valve control water meter actuator packoff, comprise water meter actuator seal box 1 and base plate 2, outer rim at base plate 2 is provided with locating slot, U-shaped O-ring seal 3 is installed in locating slot, the lower end of water meter actuator seal box 1 is inserted in the U-shaped notch of U-shaped O-ring seal 3, the groove depth of U-shaped notch is 2.5mm-4mm, and the many at least 1mm of thickness of the Thickness Ratio notch inwall of the notch outer wall of U-shaped O-ring seal 3 are provided with V-shaped valley 6 at the top of the notch outer wall of U-shaped O-ring seal 3.The locating slot width of described base plate 2 is less than the size of water meter actuator seal box 1 and U-shaped O-ring seal 3, place water meter actuator seal box 1 in the U-shaped O-ring seal 3 with the inside and outside wall pressure of the notch of U-shaped O-ring seal to base plate 2 both sides that form the gap, and have constant decrement.Decrement is 10%-30% in theory, because the notch outer wall thickness of U-shaped O-ring seal is 2.25mm, the notch inner wall thickness of U-shaped O-ring seal is 1.25mm, so decrement should be controlled in the scope of 0.225mm-0.675mm and 0.125mm-0.375mm, repetition test is passed through on basis in theoretical data, drawing the minimal compression amount is 12%, i.e. 0.275mm and 0.15mm.The groove depth of the U-shaped notch of described U-shaped O-ring seal can't positiver sealing during less than 2.5mm between 2.5mm-4mm, and during greater than 4mm, machining precision is difficult to guarantee.Outer wall top at U-shaped O-ring seal 3 is provided with V-shaped valley 6, when Water Pressure during in V-shaped valley 6 inclined-plane, U-shaped O-ring seal 3 is compressed to base plate 2 and water meter actuator seal box 1 two sides, increase sealing force, in two side compressions, power also promotes U-shaped O-ring seal 3 downwards at U-shaped O-ring seal 3, in order to prevent that U-shaped O-ring seal 3 is subjected to displacement, U-shaped O-ring seal 3 is designed to outer thick interior thin, so that U-shaped O-ring seal 3 is more pressed is tighter, seals more and more reliable.
Outer wall in water meter actuator seal box 1 lower end is provided with the fin 4 that cooperates with the notch outer wall of U-shaped O-ring seal 3; The height of described fin 4 is not more than 0.5mm.The height of described fin is 0.5mm, has increased like this Local Contraction amount of U-shaped O-ring seal 3.
Locating slot bottom at base plate is provided with the assembly platoon pore, is provided with sealing-plug 5 in the assembly platoon pore.On U-shaped O-ring seal was packed water meter actuator seal box 1 into, when reinstalling in the locating slot of base plate, club produced certain pressure gas, pressure gas so that U-shaped O-ring seal and water meter actuator seal box can not be in place.So the locating slot bottom at base plate 2 is provided with an assembly platoon pore, with unnecessary Bas Discharged, use again sealing-plug 5 with the assembly platoon port sealing, form the vacuum chamber of a sealing, suction by vacuum chamber is installed firmly water meter actuator seal box, is difficult for throwing off.
