Abstract
The utility model discloses a two-way throttle valve for molecular sieve driver, which comprises two one-way throttle valves on one valve body, wherein the two throttle valves comprise a throttle hole, the valve body is provided with a valve core having three-prism guiding and a gas outlet at side face. The valve core is made from SF7433 rubber of 70 hardness degrees, whose one end is connected with a positioning sleeve, and the valve body at the outer side of the positioning sleeve is provided with a fastening screw. The reflux washing gas at two ends flow through a same throttle hole to realize same amount, having good drying effect and simple maintenance.
Description
Technical field
The utility model discloses a kind of mole sieve drier bidirectional throttling valve, belongs to throttle valve and makes the class technical field.
Background technique
Heatless regeneration formula molecular sieve drying cable inflator is a kind of equipment that telecommunication department is safeguarded, maintained cable.Its dry gas that act as certain pressure pours in the cable, can improve speech quality on the one hand, on the other hand, when the oversheath of cable was damaged, dry gas can prevent effectively that aqueous vapor from entering cable, can also detect charge air conditioning pressure, one changes, and reports to the police automatically.Heatless regeneration formula mole sieve drier is the core of cable inflator, and the quality of its designing quality is directly connected to the quality of exsiccator.This inflator requires the gas after the interior molecular sieve drying absorption of drying pipe A to back down the one-way throttle valve of drying tube A, major part enters the dry gas gas holder, molecular sieve in the one-way throttle valve back scrubbing drying tube B of small part drying pipe B makes the molecular sieve in the drying tube B obtain regeneration; Behind 30s, gas in the drying tube B after the molecular sieve drying absorption backs down the one-way throttle valve of drying tube B, major part enters the dry gas gas holder, molecular sieve in the one-way throttle valve back scrubbing drying tube A of small part drying pipe A, make the molecular sieve in the drying tube A obtain regeneration, go round and begin again, thereby make two jars alternately regeneration of molecular sieve.But owing to adopted two one-way throttle valves, two jars back scrubbing amount to be difficult to adjust unanimity, the regeneration degree of depth of molecular sieve is also just different, has a strong impact on the quality of dry gas.
Summary of the invention
At the deficiencies in the prior art, the utility model provides the mole sieve drier that a kind of performance of ventilating is good, drying effect is good bidirectional throttling valve.
The utility model is achieved through the following technical solutions:
The utility model is that two one-way throttle valves are integrated on the valve body, and on two throttle valve bodys a throttle orifice is arranged, and wherein, in the described valve body spool is arranged, and spool is the triangular guiding and there is the air outlet side.
It is that 70 SF7433 sizing material is made that described spool adopts hardness, and the one end is connected with setting sleeve, on the valve body outside the setting sleeve fastening screw is arranged.
The utility model A, B end is suction port, and the O end is the air outlet.Under the effect of control gear, the A end is for the gas that certain pressure is arranged, the B end stops air feed, slide valve moves right under the effect of gas, seal B end suction port, gas enters air outlet hole through slide valve center hole, sidewall radial hole, and small part enters the B end through slide valve centromere discharge orifice, the molecular sieve of back scrubbing B end; Behind the 30s, the B end is for the gas that certain pressure is arranged, and the A end stops air feed, slide valve is moved to the left under the effect of gas, seals A end suction port, and gas enters air outlet hole through slide valve center hole, sidewall radial hole, small part enters the A end through slide valve centromere discharge orifice, the molecular sieve of back scrubbing A end.Because the back scrubbing gas at two ends is all by same throttle orifice, the back scrubbing gas flow at A, B two ends equates that the utility model drying effect is good, makes design, use, the maintenance of exsiccator very convenient.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model spool view;
Fig. 3 is the sectional view of spool along A '-A ' line.
Wherein, 1, fastening screw, 2, the sealing setting sleeve, 3, slide valve, 4, valve body, 5, sealing gasket.
Embodiment
Embodiment: structure such as Fig. 1, Fig. 2, shown in Figure 3, the utility model is that two one-way throttle valves are integrated on the valve body 4, and a throttle orifice is arranged on two throttle valve bodys, wherein, in the described valve body spool is arranged, slide valve 3 movably just, slide valve 3 is the triangular guiding and there is the air outlet side.It is that 70 SF7433 sizing material is made that described spool adopts hardness, and the one end is connected with sealing setting sleeve 2, on the valve body outside the setting sleeve fastening screw 1 is arranged.Sealing gasket 5 is arranged between slide valve 3 and valve body.
On valve body, A, B end is suction port, and the O end is the air outlet.When the work of A end exsiccator, dried gas enters valve body 4 through suction port A, sealing setting sleeve, the gas of most of gas (2/3～4/5) brings out gas through O, the gas of small part gas (1/5～1/3) enters B end exsiccator through the B end, molecular sieve in the back scrubbing B exsiccator makes the molecular sieve in the B exsiccator obtain regeneration; In like manner, when the work of B end exsiccator, gas enters valve body 4 through B, the gas of most of gas (2/3～4/5) brings out gas through O, the gas of small part gas (1/5～1/3) enters A end exsiccator through the A end, and the molecular sieve in the back scrubbing A exsiccator makes the molecular sieve in the B exsiccator obtain regeneration.Go round and begin again, thereby reach the purpose of heatless regeneration.
