Abstract
The invention discloses a low leakage type pot cover valve. The low leakage type pot cover valve comprises an upper valve body (6), a lower valve body (1), a valve core (2), a valve rod (21) and a valve seat (7), wherein a plate spring (12) is arranged on the inner wall of the lower valve body (1), and the plate spring (12) is connected with the valve core (2) through a bracket (13); and the valve seat (7) is a one-way valve seat, and the one-way valve seat (7) is positioned between the upper valve body (6) and the upper part of the valve core (2). According to the low leakage type pot cover valve disclosed by the invention, the floating principle of the valve core is utilized, and the increase in pressure and temperature of a steam cooker causes the valve core to ascend and enables the upper part of the valve core to be abutted against the one-way valve seat, so that sealing specific pressure is increased and sealing is more reliable; and the unique design of the plate spring can enable the lower valve body to provide stronger pre-tightening force for the valve core, so that when the pot cover valve is under low pressure, the pot cover valve can ensure the effective sealing between the valve core and the one-way valve seat, as well as between the valve core and the upper valve body. The sealing effect of the pot cover valve disclosed by the invention is very ideal, the service life is obviously prolonged, and the pot cover valve is particularly suitable for steam cookers.
Description
Technical field
The present invention relates to a kind of valve, specifically relate to a kind of ball valve.
Background technique
In recent years along with the rise of paper-making pulping replacing and digesting technoloy, the pot cover valve that is used to be installed in the steam cooker material feeding mouth is widely applied, and this pot cover valve belongs to the ball valve class, its Application and implementation the automation fill material, improved the efficient of fill material greatly.Existing pot cover valve is by upper valve body, following formations such as valve body, spool (spherical), valve rod, valve seat, and wherein: spool is contained on the valve rod, and valve seat seals for bivalve seat design up and down, and valve core sealed cover is upper and lower two.Particularly when being specifically designed to the open and close steam cooker, hard seal valve seat contacts with spool this pot cover valve all the time, bigger, the life-span weak point that weares and teares, and sealing effect is not really desirable, can not be advantageously applied to steam cooker.In addition, the inner chamber of pot cover valve also exists the delay of fiber raw material sometimes, is prone to cause the stuck of valve, makes the decoction system operation undesired.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and provide a kind of sealability good low leakage type pot cover valve.
The object of the invention is realized through following technological scheme: a kind of low leakage type pot cover valve, comprise upper valve body, following valve body, spool, valve rod and valve seat, and on the inwall of said valve body down, leaf spring is housed, this leaf spring joins through carriage and spool; Said valve seat is unidirectional valve seat, and this unidirectional valve seat is between the top of upper valve body and spool.
After adopting structure of the present invention, this pot cover valve is contained on the steam cooker, along with the rising of the pressure and temperature of steam cooker, utilizes the floating principle of spool, spool top is adjacent to unidirectional valve seat toward rising to make spool, has increased seal pressure and makes sealing more reliable; Unique leaf spring design can make down valve body to spool stronger pretightening force is provided, and makes this pot cover valve when low pressure, also can guarantee the effective sealing between spool and unidirectional valve seat, the upper valve body.The present invention is leaked seldom, and sealing effect is very good, and also be significantly improved working life, is specially adapted to steam cooker.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the present invention is made further detailed description.
Fig. 1 is the structural representation of the low leakage type pot cover valve of the present invention.
Fig. 2 is the A-A view of Fig. 1.
Embodiment
Can know with reference to Fig. 1, Fig. 2; The present invention hangs down leakage type pot cover valve; Comprise upper valve body 6, following valve body 1, spool 2, valve rod 21 and valve seat 7 (between valve rod 21 and the following valve body 1 Gland 20 and filler 19 being housed); On the inwall of said valve body 1 down, leaf spring 12 (have four, be four direction) is housed, this leaf spring 12 joins through carriage 13 and spool 2; Said valve seat 7 is unidirectional valve seat, and this unidirectional valve seat 7 is in (top that is spool 2 joins with this unidirectional valve seat 7) between the top of upper valve body 6 and spool 2.
Wherein: also have support 27 and flat key 28 on the outer end of valve rod 21; Link to each other through pad 3, stud bolt 4 and nut 5 between upper valve body 6 and the following valve body 1.Also can be to have boss 30 on the inwall of said down valve body 1, on this boss 30, leaf spring 12 is housed through cushion block 10 and straight pin 11.This boss 30 is structure as a whole with following valve body 1.
In order to respond to the pressure size in the upper and lower valve body, between said upper valve body 6 and following valve body 1, locate to be equipped with side flange 23, pressure transducer 29 (this pressure transducer links to each other with final controlling element) is housed on this side flange 23.Be higher than when the steam cooker internal pressure under the situation of setting pressure, pressure transducer transmits lock control signal, make final controlling element be in closed condition and remain close, akinesia, in order to avoid that pot inner pressure is revealed and produced is dangerous; After boiling completion, material discharging, when pot inner pressure was lower than security settings pressure, pressure transducer transmitted start signal, and pressure is chain to be opened, and final controlling element can drive valve open, realizes charging once more.
In order more to strengthen the sealability between one-way valve seat and the upper valve body, on the lengthwise position between said unidirectional valve seat 7 and the upper valve body 6, be equipped with sealing gasket 8 is housed on seal ring 9, the lateral attitude.As shown in the figure, said spool 2 is global face shape design, has upper and lower two sealing surfaces (promptly the top of this spool and bottom all have sealing surface) on its sphere and can use (be equivalent to a plurality of spools and make spare part) in turn, prolongs its working life; Said spool 2 has guaranteed the quick filling of chip for latus rectum designs, and the valve pocket passage is smooth and easy and prevent that valve pocket from piling up material, has improved the efficient that the steam cooker material is filled greatly.
Can the present invention be contained on the steam cooker, be used to open and close steam cooker, be equivalent to the pot cover with valve effect is installed on steam cooker, its keying speed is fast, high working efficiency, and sealability is high, and fill material is quick.
