Description

疫苗专用隔膜阀 Vaccines special diaphragm valve

技术领域 FIELD

本实用新型为一种阀,尤其是一种疫苗专用隔膜阀,它广泛应用在疫苗生产设备及其它需要用蒸汽高温消毒的生物设备管路中。 This invention is to a valve, in particular a vaccine special diaphragm valve, it is widely used in the production of vaccines and other biological devices pipeline equipment needed in the high-temperature steam sterilized.

背景技术 Background technique

目前,国内在生物工程中生产疫苗的反应器设备上应用的隔膜阀,采用的是单一弧面密封,一般能达到技术要求,但阀门关闭无限位,常常因对膜片过载加压,缩短了阀门的使用寿命,再由于管道内冷、热交替频繁,使膜片在热胀冷缩情况下,常因膜片收缩,压力得不到自动补偿而造成密封面泄漏。 At present, the production of the diaphragm valve in Biotechnology applied on reactor apparatus vaccine uses a single arc sealed, generally meet the technical requirements, but the valve is closed limit position, often due to pressure overload membrane, shortening life of the valve, since then the cold pipe, heat alternately frequent thermal expansion and contraction of the diaphragm in the case, often due to the contraction of the diaphragm, the pressure can not be automatically compensated leakage caused by the sealing surface. 由于上述原因,致使生物产品在生产过程中因为染菌而产量低、品质和效益差。 For these reasons, resulting in biological products because of contamination in the production process and low yield, quality and poor efficiency.

发明内容 SUMMARY

本实用新型目的是要提供一种能在高温蒸汽管路中,阀门关闭能限位,压力上能进行自动补偿,使得突然冷却时,膜片不再产生收缩间隙,且仍保持密封状态的疫苗专用隔膜阀。 The present invention aims to provide a high temperature in the steam line, the valve can be closed limit, the pressure can be automatically compensated, so that a sudden cooling, no contraction of the diaphragm gap, and still maintain the sealed state vaccine special diaphragm valve.

本实用新型的技术方案是:在阀体上平面于介质进出口的沿口上,设置一个环状且截面呈半园形的密封面,再在密封面上、下端之间连接一条凹面朝上的弧形密封面,两密封面的交接处为切线平滑过渡状。 Aspect of the present invention is: in the valve body to the medium plane along the export port, and provided an annular semi-circular cross section of the sealing surface, and then connected to an upwardly concave surface between the sealing surface, the lower end an arcuate sealing surface, the sealing surfaces of the two tangential junction to form a smooth transition.

由于采用了以上技术方案,其效果是非常明显的:1、密封性能更加可靠。 With the above technical solution, the effect is very obvious: 1, more reliable sealing performance.

2、既保证了阀门密封,又保证了膜片不遭到过载压力而受到破坏,延长了阀的使用寿命。 2, both to ensure the valve seal and ensures the film was not damaged the overload pressure, prolong the service life of the valve.

本实用新型包括阀盖(4)、阀体(7)、阀盖和阀体之间用螺栓装上的膜片(6),在膜片上方有穿出阀盖的阀杆(3),阀杆(3)顶部装有手轮(1),在手轮内设置套在阀盖上端部上并可以调节阀杆行程的限位套(2)。 The present invention includes a valve cap (4), the valve body (7), between the valve cover and valve body with the diaphragm (6) mounted on the bolt, above the valve stem piercing the membrane of the bonnet (3), a valve stem (3) surmounted by a hand wheel (1), and the sleeve can be provided with adjustable stem stroke stopper sleeve (2) at the cap end of the valve handwheel. 阀杆(3)与膜片(6)之间用连接套(8)和卡箍圈(9)相连,并在连接套(8)的内腔安置一弹性补偿垫(5)。 Between the stem (3) and the diaphragm (6) is connected with the sleeve (8) and clamp ring (9) is connected to, and positioned a resilient compensating pad (5) in the connection sleeve (8) lumen. 如图2所示,阀体上端面为一平面(12),在平面中间于介质进出口的沿口上,设置一环状且截面呈半圆形的密封面(11),在密封面(11)的上下端之间连接一条凹面朝上的弧形密封面(10),两密封面的交接处呈切线平滑过渡状。 2, a planar end surface (12) on the valve body, the mid-plane of the import and export to the medium along the mouth, provided with a semicircular cross section and an annular sealing surface (11), the sealing surface (11 is connected between an upward concave) curved upper and lower ends of the sealing surface (10), the junction of the two sealing surfaces form a smooth transition tangentially.

图1中,本阀处于开启状态,当关闭本阀时,只需将手轮(1)顺时针旋转,这时,手轮带动限位套(2)、阀杆(3)、连接套(8)、膜片(6)同步下移,使膜片紧压在密封面(10)和(11)上,达到密封而不泄漏的目的。 1, this valve is open, this valve when closed, only the hand wheel (1) is rotated clockwise, this time, driven by the handwheel stopper sleeve (2), a valve stem (3), the connection sleeve ( 8), the membrane (6) synchronized down the object of the diaphragm is pressed against the sealing surface (10) and (11), to achieve sealing without leakage. 此时,限位套(2)内部的上平面正好与阀盖(4)的上端面相抵而定位,不至于因压力过载使膜片(6)容易损坏。 At this time, the stopper sleeve (2) on the plane end surface just inside of the valve cover (4) is positioned against, and will not cause an overload due to a pressure membrane (6) is easily damaged. 假如管道中介质突然冷却,膜片向上收缩而产生间隙,就有可能产生泄漏,这时,阀杆下面的弹性补偿垫(5)自动张开,产生压力补偿,迫使膜片下移,达到补充间隙的目的,杜绝了因冷热交替造成的阀门泄漏。 If sudden cooling medium conduit, the gap upward contraction of the diaphragm, leak is likely, then, the valve stem following elastic compensation pad (5) automatically open, a pressure compensation, forcing the diaphragm down, to supplement the purpose of the gap, to prevent the leakage of the valve caused by alternating hot and cold.
