Abstract
The utility model discloses an aluminum angle valve for pumping outside inner parts. The aluminum angle valve comprises a valve body, a valve base, a valve core, a valve rod, a lower valve cover and an upper valve cover. The lower valve cover is fixedly connected with the valve body through a screw, the upper valve cover is fixedly connected with the lower valve cover through a screw, and the valve rod drives the valve core to move up and down to achieve opening and closing of the valve. The aluminum angle valve is characterized in that a guide sleeve is arranged on the lower portion of the valve rod, the guide sleeve is guided by a guide hole formed in the lower valve cover, and the hole diameter of the guide hole is larger than the maximum external diameter of the valve core and is smaller than the hole diameters of inner holes of other portions of the lower valve cover. The aluminum angle valve for pumping outside the inner parts is used in an air separation box and a large-scale cryogenic liquid storage tank, has the advantages of being convenient to maintain and low in maintaining cost, and can achieve zero leakage which is strictly required.
Description
Technical field
The utility model relates to a kind of aluminum alloy angle valve that is applied in air separation ice chest and the large-scale low-temperature liquid storage vessel.
Background technique
Low temperature aluminium angle valve (the aluminium angle valve refers to the angle valve that adopts the aluminum alloy material valve body) is mainly used in air separation ice chest and the large-scale low-temperature liquid storage vessel, because the empty common adiabatic form of the common employing of insulation of dividing ice chest and large-scale low-temperature liquid storage vessel, the material (being generally pearlife) that namely the filling thermal conductivity is little in thermal insulation layer (interlayer) reaches the purpose that reduces the external heat intrusion with this.Present present situation is: whenever valve breaks down, will open ice chest and claw the part pearlife, and valve be taken out keep in repair then, this will cause very big maintenance expenses, has the time to claw the loss that pearlife causes and just reaches hundreds of thousands unit.In addition, Subzero valve very general of phenomenon that leak outside, because the internal-external temperature difference great disparity, valve gap stuffing box place freezes easily, the moving up and down of back valve rod of freezing easily caused the destruction to packing box seal, causes to leak outside.
Summary of the invention
Problem in view of present known technology existence, the technical problems to be solved in the utility model is to be to provide a kind of to be applied in air separation ice chest and the large-scale low-temperature liquid storage vessel, and is easy to maintenance, maintenance cost is low, reach the outer odd test aluminium angle valve of internals of strict zero leakage requirement.
The utility model is implemented by the following technical programs:
The outer odd test aluminium angle valve of internals, comprise valve body, valve seat, spool, valve rod, bottom flange and bonnet, bottom flange is fixedlyed connected with valve body by screw, bonnet is fixedlyed connected with bottom flange by screw, valve rod drives spool and moves up and down opening or closing of realization valve, it is characterized in that: the bottom of valve rod is provided with guide sleeve, and guide sleeve is led by the pilot hole that bottom flange is provided with, and the aperture of pilot hole is greater than the maximum outside diameter of spool and less than the endoporus aperture of bottom flange remaining part.Endoporus at bottom flange is provided with metal bellows, and the lower end of metal bellows is connected on the valve rod, and the upper end is connected on the positioning disk, and positioning disk is fixed in the connection end of last bottom flange.Be provided with packing box seal in the bonnet.
After adopting technique scheme, the valve maintenance time need not be opened ice chest and be pushed pearlife aside and take out valve, and only need remove the valve bonnet, then with trim whole take out to keep in repair get final product, not only realized the convenience of maintenance, the more important thing is to greatly reduce maintenance cost.In addition, the utility model has also adopted metal bellows to seal, and good sealing effect can be avoided freezing of packing box seal, and metal bellows and packing box seal duplicate protection have satisfied the zero leakage requirement of valve strictness fully.Also have, arranging of guide sleeve can make moving up and down accurately of valve rod be led, and increased the intensity of valve rod, realized that spool and valve seat better seal.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Embodiment
Describe relevant details and the working principle of the utility model specific embodiment in detail below in conjunction with accompanying drawing:
As shown in the figure, the outer odd test aluminium angle valve of internals of the present utility model, comprise valve body 1, valve seat 2, spool 3, valve rod 6, bottom flange 7 and bonnet 8, bottom flange 7 is fixedlyed connected with valve body 1 by screw, bonnet 8 is fixedlyed connected with bottom flange 7 by screw, valve rod 6 drives spool 3 and moves up and down opening or closing of realization valve, the bottom of valve rod 6 is provided with guide sleeve 4, guide sleeve 4 is led by the pilot hole 5 that bottom flange is provided with, the aperture of pilot hole 5 is greater than the maximum outside diameter of spool 3 and less than the endoporus aperture of bottom flange 7 remaining parts, endoporus at bottom flange is provided with metal bellows 11, the lower end of metal bellows 11 is welded to connect on valve rod 6, the upper end is welded to connect on positioning disk 10, and positioning disk 10 is fixed in the end that is connected of bonnet 8 and bottom flange 7, is provided with packing box seal 9 in the described bonnet 8.When the utility model was installed in ice chest, above position, the middle part of bottom flange 7 exposed to ice chest cover plate 12.
