本文中,在弹性体的压力作用下组成移动副的两个构件的平面紧密贴合在一起。Herein, the planes of the two members constituting the moving pair are closely attached together under the pressure of the elastic body.
本发明的有益效果如下:The beneficial effects of the present invention are as follows:
1、由于采用阀板来开闭主阀体的过料孔,且阀板以可轴向移动的方式安装于拖动体的安装孔内。从而物料作用在阀板上的力直接传递给与之组成移动副的另一构件(例如:滑动压板、副阀体、过料板或主阀体),而不会或很少作用在拖动体上。进一步而言,物料压力不能或极少传导给滑杆(或与拖动体直接相联的驱动装置的活塞杆),滑杆(或活塞杆)不受径向力作用和径向力极小,减轻了滑杆(或活塞杆)与导板(或与活塞杆对应的引导件)之间的磨损,使滑杆(或活塞杆)与其密封之间的保持较高的同轴度,防止了密封性能的降低,提高了滑杆密封的可靠性。1. The valve plate is used to open and close the through hole of the main valve body, and the valve plate is installed in the mounting hole of the drag body in an axially movable manner. Therefore, the force acting on the valve plate is directly transmitted to another component that constitutes the moving pair (for example, a sliding platen, a secondary valve body, a feed plate or a main valve body), and does not or rarely acts on the drag Physically. Further, the material pressure cannot be transmitted to the slider (or the piston rod of the drive unit directly connected to the drag body), and the slide rod (or piston rod) is not subjected to radial force and the radial force is extremely small. , which reduces the wear between the slide bar (or the piston rod) and the guide plate (or the guide member corresponding to the piston rod), so as to maintain a high degree of coaxiality between the slide bar (or the piston rod) and the seal thereof, thereby preventing The reduction in sealing performance improves the reliability of the slider seal.
2、由于滑杆(或活塞杆)与滑板(或相应引导件)之间的径向力很小或没有径向力,并且径向力也不受物料压力的影响,因此可用于具有更大物料压力的设备和管道输送系统。2. Since the radial force between the slide bar (or piston rod) and the slide plate (or the corresponding guide member) is small or no radial force, and the radial force is not affected by the material pressure, it can be used for larger materials. Pressure equipment and piping systems.
另外,对于输送泵,进一步具有下述优点:In addition, for the transfer pump, it has the following advantages:
由于拖板滑阀的密封更可靠,且可用于具有更大物料压力的设备和管道输送系统,使的使用其的本发明的拖板滑阀的输送泵能够具有更大的泵送压力,并具有更高的可靠性和更长的使用寿命。Since the sealing of the carriage slide valve is more reliable and can be used for equipment and piping systems having greater material pressure, the delivery pump of the carriage slide valve of the present invention using the same can have greater pumping pressure, and Higher reliability and longer life.

具体实施方式detailed description
下面结合附图来描述本发明的具体实施方式,这里的具体实施方式在于详细地说明本发明,而不应理解为对本发明的限制。The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
实施例一Embodiment 1
参见图1、图2和图3,其中示出了本发明一个优选实施例的拖板滑阀的示意图。图示的拖板滑阀包括:驱动装置1、副阀体2、滑动压板3、通孔体6、第一弹性体7a、第二弹性体7b、拖动体8、阀板9、主阀体11。Referring to Figures 1, 2 and 3, there is shown a schematic view of a carriage slide valve in accordance with a preferred embodiment of the present invention. The illustrated slide plate slide valve includes: a driving device 1, a sub valve body 2, a sliding platen 3, a through hole body 6, a first elastic body 7a, a second elastic body 7b, a drag body 8, a valve plate 9, and a main valve. Body 11.
其中,主阀体11上有一个过料孔,物料可以从主阀体11的过料孔中通过;通孔体6上设置有通孔;拖动体8上设置有安装孔;第一弹性体7a和第二弹性体7b是具有密封功能的弹性密封件,其可以是橡胶密封圈、聚氨酯密封圈或聚四氟乙烯密封圈等;驱动装置1是液压缸或气缸。Wherein, the main valve body 11 has a through hole, the material can pass through the through hole of the main valve body 11; the through hole body 6 is provided with a through hole; the drag body 8 is provided with a mounting hole; the first elasticity The body 7a and the second elastic body 7b are elastic seals having a sealing function, which may be rubber seals, polyurethane seals or Teflon seals, etc.; the drive device 1 is a hydraulic cylinder or a cylinder.
副阀体2和主阀体11联接在一起,拖动体8位于副阀体2和主阀体11之间。具体地,参见图1-3,滑动压板3安装在副阀体2和主阀体11之间。拖动体8位于滑动压板3和主阀体11之间。驱动装置1与主阀体11相联,驱动装置1的活塞杆与拖动体8相联。阀板9和第一弹性体7a安装在拖动体8的安装孔内并封堵安装孔,且第一弹性体7a位于阀板9和拖动体8之间,第一弹性体7a将阀板9压在滑动压板3上,并在阀板9和拖动体8之间形成密封,阀板9和滑动压板3的接触面组成一个移动副。通孔体6和第二弹性体7b安装在主阀体11的过料孔内,且第二弹性体7b位于通孔体6和主阀体11 之间,第二弹性体7b将通孔体6压紧在拖动体8上,并在通孔体6和和主阀体11之间形成密封,通孔体6和拖动体8的接触面组成一个移动副。阀板9、第一弹性体7a和拖动体8组成阀板组件,副阀体2和主阀体11限定该阀板组件的轴向位置,需要指出的是,副阀体2不限于图示的结构与形状,而是可以采用任何适当结构与形状,只要能够与主阀体组合限定该阀板组件的轴向位置即可,甚至,副阀体可以是与主阀体一体成型的一部分,滑动压板3也可以视为副阀体的一部分。The sub valve body 2 and the main valve body 11 are coupled together, and the drag body 8 is located between the sub valve body 2 and the main valve body 11. Specifically, referring to Figs. 1-3, the sliding platen 3 is installed between the sub valve body 2 and the main valve body 11. The drag body 8 is located between the sliding platen 3 and the main valve body 11. The drive unit 1 is coupled to the main valve body 11, and the piston rod of the drive unit 1 is coupled to the drag body 8. The valve plate 9 and the first elastic body 7a are installed in the mounting hole of the drag body 8 and block the mounting hole, and the first elastic body 7a is located between the valve plate 9 and the drag body 8, and the first elastic body 7a is a valve The plate 9 is pressed against the sliding platen 3, and a seal is formed between the valve plate 9 and the drag body 8, and the contact faces of the valve plate 9 and the sliding platen 3 constitute a moving pair. The through hole body 6 and the second elastic body 7b are installed in the through hole of the main valve body 11, and the second elastic body 7b is located in the through hole body 6 and the main valve body 11 Between, the second elastic body 7b presses the through hole body 6 against the drag body 8, and forms a seal between the through hole body 6 and the main valve body 11, and the contact between the through hole body 6 and the drag body 8 The faces form a mobile pair. The valve plate 9, the first elastic body 7a and the drag body 8 constitute a valve plate assembly, and the auxiliary valve body 2 and the main valve body 11 define the axial position of the valve plate assembly. It should be noted that the auxiliary valve body 2 is not limited to the drawing. The structure and shape are shown, but any suitable structure and shape may be employed as long as it can be combined with the main valve body to define the axial position of the valve plate assembly, and even the auxiliary valve body may be a part integrally formed with the main valve body. The sliding platen 3 can also be considered as part of the secondary valve body.
在驱动装置1的作用下,拖动体8连同安装在拖动体8安装孔内的第一弹性体7a和阀板9可以一起往复运动,从而打开或关闭主阀体11上的过料孔。可以理解的是,在关闭主阀体11上的过料孔时,安装孔(或者说阀板9)与过料孔相通,从而,物料压力直接作用于阀板9并通过阀板9传递至滑动压板3再由滑动压板3进一步传递至副阀体2,而使拖动体8对活塞杆的径向力很小或无径向力。Under the action of the driving device 1, the drag body 8 together with the first elastic body 7a and the valve plate 9 installed in the mounting hole of the drag body 8 can reciprocate together, thereby opening or closing the through hole on the main valve body 11. . It can be understood that when the through hole on the main valve body 11 is closed, the mounting hole (or the valve plate 9) communicates with the through hole, so that the material pressure acts directly on the valve plate 9 and is transmitted through the valve plate 9 to The sliding platen 3 is further transmitted by the sliding platen 3 to the secondary valve body 2, so that the radial force of the drag body 8 against the piston rod is small or no radial force.
当滑动压板3和阀板9的移动副的摩擦面以及通孔体6和拖动体8的移动副的摩擦面产生磨损时,在第一弹性体7a和第二弹性体7b的弹力作用下,阀板9和通孔体6将进行相应的位移以补偿磨损量,使滑动压板3和阀板9以及通孔体6和拖动体8的移动副继续保持压紧状态。When the friction surface of the moving pair of the sliding platen 3 and the valve plate 9 and the friction surface of the moving body of the through hole body 6 and the drag body 8 are worn, under the elastic force of the first elastic body 7a and the second elastic body 7b The valve plate 9 and the through-hole body 6 will be correspondingly displaced to compensate for the amount of wear, so that the sliding platen 3 and the valve plate 9 and the moving pair of the through-hole body 6 and the drag body 8 continue to be pressed.
以下是其工作方式的一个实施例:The following is an example of how it works:
主阀体11连通于物料的高压端,当处于图1所示的工作位置时,主阀体11的过料孔被关闭,在第二弹性体7b和物料的压力作用下,通孔体6被紧压在拖动体8上,在通孔体6和拖动体8的接合面形成刚性密封,以阻止物料从通孔体6和拖动体8的接合面处泄漏。当拖动体8移动时,主阀体11的过料孔逐渐被打开。The main valve body 11 communicates with the high pressure end of the material. When in the working position shown in Fig. 1, the through hole of the main valve body 11 is closed, and the through hole body 6 is under the pressure of the second elastic body 7b and the material. It is pressed against the drag body 8 to form a rigid seal at the joint surface of the through hole body 6 and the drag body 8 to prevent material from leaking from the joint faces of the through hole body 6 and the drag body 8. When the drag body 8 moves, the through hole of the main valve body 11 is gradually opened.
