Description
Technical field
The invention belongs to fill with and be coated with technical field, the cut-off and the adjustable flow that are applicable to fluid are released, are freely released.
Background technique
Slender rectangular tube is as the critical component of certain product, and its inwall increases refractory layer according to usage requirement.The safety and reliability that its property relationship uses to product.Therefore the rationality of the coated technique of this thermal-protective coating is vital.
In order to ensure inside coating quality, its coated technique, for be poured into from below to up in slender rectangular tube by coating, leaves standstill a period of time, then releases from below, and require that flow is adjustable.This just needs to arrange the simple unidirectional adjustable flow release valve of a kind of structure.
Do not have at present to meet this one-way valve required.A kind of unidirectional adjustable modulating valve of releasing is proposed for this demand.
Summary of the invention
The technical problem that the present invention solves is the two-way valve proposing a kind of unidirectional adjustable flow, in order to solve the coated technique of the inwall thermal-protective coating of the critical component slender rectangular tube of certain product, coating is poured in slender rectangular tube from below to up, and requires that flow is adjustable.This valve is applicable to the cut-off of fluid and adjustable flow is released, freely released, and being mainly applicable to medium is normal-pressure liquid material.
The technical solution adopted in the present invention is: a kind of two-way valve of unidirectional adjustable flow, and this valve comprises the seat of honour, lower seat, thimble, steel ball, copperhead; The described seat of honour has inner cavity, and inner cavity top is frustum cone structure, and bottom is cylindrical, and frustum cone structure cavity osculum is communicated with cylindrical cavity; Described lower seat is fixedly connected with the seat of honour; Xia Zuo center has cavity, and the inner cavity at the seat of honour and the cavity of lower seat form fluid passage; Described thimble comprises push rod, sliding bar and connecting rod; The top welding steel ball of push rod, the diameter of steel ball is greater than the cylindrical cavity diameter at the seat of honour; Sliding bar is cylindrical bar, and sliding bar periphery coordinates with the cylindrical cavity inwall of bottom, the seat of honour, and thimble can be moved up and down in the inner cavity at the seat of honour; Sliding bar end face several axial holes uniform, as fluid passage; Steel ball and seat of honour frustum cone structure cavity are formed and contact when sealing, and connecting rod lower end head stretches out from the oral area of lower seat lower end; Described copperhead is fixed on thimble lower end head.
The invention has the beneficial effects as follows: structure of the present invention is simple, compact, low cost of manufacture is easy to maintenance.The valve of unidirectional regulating flow quantity can be realized; And according to traffic demand, can highly regulate by regulating the jack-up of thimble 2 flow passed through.
Material of the present invention except copperhead 4 be that except brass, all the other are stainless steel.Sealing is the linear sealing between steel ball two metal of top seat 1 and thimble 2 end, therefore the medium temperature be suitable for is very extensive, and safe and reliable.
Accompanying drawing explanation
The present invention has 2 width accompanying drawings.
Fig. 1. be the structural representation of the two-way valve of a kind of unidirectional adjustable flow of the present invention;
Fig. 2. be the structural representation of the two-way valve opening state of a kind of unidirectional adjustable flow of the present invention;
Wherein, the 1-seat of honour, 2-thimble, seat under 3-, 4-copperhead.
Embodiment
Below in conjunction with accompanying drawing, most preferred embodiment of the present invention is further described.
As shown in Figure 1, 2, the two-way valve of a kind of unidirectional adjustable flow of the present invention, this valve comprises the seat of honour 1, lower seat 3, thimble 2, steel ball, copperhead 4; The seat of honour 1 connects with lower seat 3, middle formation fluid passage; Upper fluid passage lumen inside is provided with the thimble 2 that welding edges has steel ball, and the middle of thimble 2 is provided with large-area as far as possible through hole, passage when opening as fluid.This unidirectional adjustable flow modulating valve can be fixed by bolts on assembling set by the hole on the seat of honour 1.Copperhead 4 is fixed on thimble 2 lower end.
This valve comprises the seat of honour 1, lower seat 3, thimble 2, steel ball, copperhead 4; Have inner cavity in the middle of the seat of honour 1, inner cavity top is frustum cone structure cavity, and the bottom of inner cavity is cylindrical cavity, and frustum cone structure cavity bottom osculum is communicated with cylindrical cavity, is fixedly connected with lower seat 3 by the bolt seat of honour 1; Lower seat 3 center has cavity, and the inner cavity at the seat of honour 1 and the cavity of lower seat form fluid passage; And the upper end of lower seat 1 has round ring boss, boss is positioned at the seat of honour 1 cavity, and the periphery of boss coordinates with the round column structure cavity inner wall of bottom, the seat of honour 1, and ensures sealing.
Thimble 2 comprises push rod, sliding bar and connecting rod, and three parts connect respectively from top to bottom; The top welding steel ball of push rod, the diameter of steel ball is greater than the seat of honour still allows the cylindrical cavity diameter in people portion for 1 time; Sliding bar is cylindrical bar, and sliding bar periphery coordinates with the cylindrical cavity inwall of bottom, the seat of honour 1, and thimble 2 can be moved up and down in the inner cavity at the seat of honour 1; Several axial holes uniform in circumferential end surfaces on sliding bar, as fluid passage; The diameter of push rod is generally less than the distance on sliding bar between hole; Sliding bar is the maximum diameter part of thimble 2, and the diameter of sliding bar is greater than the internal diameter of lower seat round ring boss; Connecting rod lower end head stretches out a segment length from the oral area of lower seat 3 lower end.
Copperhead is fixed on the center hole of the connecting rod lower end of thimble 2 by interference fit.
The material of the two-way valve of unidirectional adjustable flow of the present invention, the material of copperhead 4 is brass, improves the Security of this valve.Except copperhead 4 is that except brass, all the other are stainless steel.Sealing is the line contact sealing between top seat 1 and steel ball 2 liang of metals, and not by the rubber material of temperature limiting, therefore the medium temperature be suitable for is very extensive; Because the material of copperhead is material of misfiring, can be applicable to the occasion of explosion risk, safe and reliable.
In Material selec-tion, the material of copperhead 4 is H62.The seat of honour 1, thimble 2, the material of lower seat 3 is stainless steel, also can adopt other materials, as carbon steel chromium plating.
The operating principle of the two-way valve of unidirectional adjustable flow of the present invention is: when thimble 2 is not by jack-up time, and thimble 2 falls naturally by gravity, achieves the closing process of the two-way valve of this unidirectional adjustable flow; When thimble 2 moves upward jack-up due to the effect in the external world time, annular space is formed between the steel ball on thimble 2 top and the seat of honour 1, the medium on the two-way valve top of this unidirectional adjustable flow enters in thimble 2 in fluid channels through above-mentioned annular space, then naturally flows out, realizes releasing.Further, along with the jack-up of thimble 2, the steel ball on thimble 2 and the gap between the seat of honour 1 progressively increase, and the flow passed through also just increases gradually.Namely the height of thimble 2 is regulated just can to regulate the flow passed through.The height of thimble 2 jack-up can regulate according to traffic requirement.
