The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 1 to Figure 12 has schematically shown according to the overall structure of the drain valve of the embodiment of the invention and the structure of each several part.As shown in the figure,
Drain valve according to the embodiment of the invention comprises: drainage arrangement 200 and dust guard,
Valve rod 10 is arranged in the cavity of valve body 20, and the upper end of valve rod 10 is provided with cannelure 18, and cannelure 18 is provided with first sealing member 110; First sealing member 110 has the structure that is fit to sealing primary sealing area 21, and for example, first sealing member 110 is an O shape silica gel sealing ring;
Valve rod 20 has makes first sealing member 110 be positioned at the position of first screw 701 and the position of stretching out first screw 701, and the length that promptly designs the position of cannelure 18 and valve rod 20 is to guarantee two kinds of effects of sealing and draining;
Dust guard comprises:
Lower tray piece 80 is used for being tightly connected with sodica calx canister assembly (not shown), and lower tray piece 80 is provided with dustproof pallet 90;
Preferably, drainage arrangement 200 also comprises: Flexible Reset parts 30 are arranged between valve rod 10 and the valve body 20.Utilize Flexible Reset parts 30 just can realize automatically reseting after its draining, so just can realize draining in the operation process.Preferably, Flexible Reset parts 30 are the cylindricality back-moving spring, and valve rod 10 is provided with pedestal 14, and back-moving spring is arranged on the pedestal 14 and is set in outside the valve rod 10.Like this, Flexible Reset parts simple in structure, cost is low, and effect is obvious, and the feel that slide for handle 50, be convenient to perception and adjust the position.
Preferably, valve rod 10 has axial osculum 13 and the side direction through hole 12 that interconnects, and the water capacity is easily flow in the endoporus spare 13 by the hole part 12 on valve rod spare 10 circumference.
Preferably, the lower end back aperture that axial osculum 13 extends to valve rod 10 becomes big, forms lower port 16; Valve rod 10 has the lower port of being opened in 16 edgewise handles and connects screw 15, and the aperture of lower port 16 connects the aperture of screw 15 greater than handle.Like this, lower port 16 has enough gaps, so water can be easy to discharge.
Preferably, the lower end of valve rod 10 has vertical outer surface 17.This is because low amounts of water can flow down from the external diameter of valve rod spare 10, for fear of flowing to handle 50 places, so will process vertical outer surface 17 on valve rod spare 10.
Preferably, valve body 20 has card platform 24, and card platform 24 is arranged on the upper end of drainage joint 40, like this, is convenient to the location.
Preferably, the upper lateral of drainage joint 40 is provided with fastening screw 401, be provided with jackscrew 120 in the fastening screw 401, the anticreep groove 23 of location jackscrew 120, it for example is cannelure, be arranged on valve body 20 outer surfaces of card platform 24 belows, jackscrew 120 pushes up is convenient to fixedlying connected of fastening drainage joint 40 and jackscrew 120 on the anticreep groove 23.
Preferably, handle 50 is laterally disposed on drainage joint 40, and like this, compact conformation is beneficial to adjustment.
Preferably, as shown in Figure 7, the upward stroke D1 of valve rod 10 is greater than the distance D 2 of the side direction through hole 12 and first sealing member 110, the water capacity is easily flow in the axial osculum 13 by the side direction through hole 12 on valve rod 10 circumference, can arrive in the lower port 16 in turn, drainage speed is very fast.
Preferably, as shown in Figure 7 and Figure 8, the upper surface that the upper end 26 of valve body 20 exceeds lower plate 70 is provided with.Like this, can guarantee below following pallet 80 enters into more intravital stickiness dirts of water storage cavity of water receiver 100, upper end 26 that impurity is deposited in valve body 20, can not enter into valve body 20 or valve rod 10, guarantee the smooth and easy of draining by draining.The distance that the upper end 26 of valve body 20 exceeds the upper surface of lower plate 70 for example can be 1mm, 2mm, and 3mm perhaps sets flexibly according to water storage cavity and other needs.
Preferably, as shown in Figure 7 and Figure 8, water hole 101 is arranged on the side top of the upper end 26 of valve body 20.Like this, the upper end 26 of valve body 20 is not positioned under the water hole 101, and the more intravital stickiness dirts of water storage cavity, the impurity that enter into water receiver 100 from following pallet 80 can not directly enter into valve body 20 or valve rod 10.From this aspect, the deviation on the vertical direction of the upper end 26 of water hole 101 and valve body 20 is the bigger the better.
Draining valve body spare 20 is press fit into sealing gasket spare 60 on the lower plate 70, thereby can guarantee that water can be from this outflow.
The basic installation process of drainage arrangement spare 200 is as follows: with Flexible Reset parts 30, pass valve rod 10, pass first screw 701 of valve body 20 and lower plate 70 then successively, again first sealing member 110 (for example being of a size of the O shape silica gel sealing ring of φ 3.2 * 1.8) is assembled to cannelure 18 places of valve rod 10 this moment.Drainage joint 40 is passed valve rod spare 10, regulate position relation between the screwed hole 15 on drainage joint 40 top screwed holes 42 and the valve rod 10, make handle 50 reach suitable installation site, use this moment 2 jackscrews 120 that drainage joint 40 is fixing thereby reach.Because jackscrew 120 is arranged on the anticreep groove 23 of valve body 20, when using excessive downward force, drainage joint 40 is unlikely to come off like this.Handle 50 is assembled in the screwed hole 15 of valve rod 10.
Under the resting state, promptly not when handle 50 applies external force, the sealing of first sealing member 110 is to rely on valve rod 10 fully, and the deadweight of handle 50 guarantees in addition.In order to make this device after being transformed into resting state, still can guarantee sealing, be to rely on the fit tolerance between the external diameter of the endoporus of drainage joint 40 and valve rod 10 to guarantee from hull-borne.In addition, due sealing state in order to guarantee between each parts to connect is provided with sealing members such as sealing ring between corresponding parts.
The draining of this drain valve in operation process is to rely on the handle piece 50 to lift, and drives valve rod spare 10, overcomes the elastic force of back-moving spring spare 30, thereby O shape circle part 110 breaks away from sealing surface, reaches the effect of draining.
The draining after operation of this drain valve is convenient, be because sodica calx canister assembly and following pallet 80 are connected by sealing ring, after pulling down sealing ring and sodica calx canister assembly, just can clear up the sodica calx granule on the dustproof pallet 90 very easily, can make then on the water receiver 100 water hole 101 down, water can be discharged to assigned address naturally.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect:
The present invention takes dustproof pallet, avoid the sodica calx granule from drainage channel to the drain valve sealing;
The present invention utilizes the deadweight of valve rod and handle can make O-ring seals be mated the face interference fit, guarantees sealing under normal conditions.
Draining of the present invention is convenient, only needs during draining handle is upwards lifted gently, and hydrops just can be discharged;
The present invention utilizes back-moving spring just can realize automatically reseting after its draining, so just can realize draining in the operation process.
The present invention is easy to leave from the lower part of sodica calx jar, makes things convenient for hydrops and particulate cleaning after the operation.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation, and under reconcilable situation, each embodiment can make up mutually.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
