Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] Such as Figure 1-Figure 7 As shown, the uniformly distributed annular pressure sealing valve of the present invention includes a positioning disc 11, a sealing outer ring 13, an elastic pressing block 7 and a sealing inner ring 5. The axis of the positioning disc 11 is connected to a transmission shaft 6 in rotation, and The cam disc 12 that can rotate synchronously with the transmission shaft 6 is installed, and the center of the cam disc 12 is symmetrically distributed with six cam ends 12-1. The secondary elastic pressure rod 10 of the transmission rod is used for radial force transmission, the secondary elastic pressure rod 10 is arranged radially along the cam disc 12, and the positioning plate 11 is provided with a radial guide for the secondary elastic pressure rod 10. The guide device, the inner end of each secondary spring pressing rod 10 is set in co...

Abstract

The invention belongs to the field of mechanical sealing valves, and particularly relates to a uniformly-distributed annular press type sealing valve and a sealing method. A cam disk is installed on a transmission shaft of the sealing valve, and the cam disk and the transmission shaft can synchronously rotate. A plurality of cam ends are distributed on the cam disk in a central symmetry mode, and transmission rods are arranged on the working surfaces of the cam ends in a contact mode and arranged in the radial direction of the cam disk. A guide device which conducts radial guiding on the transmission rods is arranged on a locating disk. The inner end of each transmission rod and the working surface of the corresponding cam end are arranged in a contact mode, and the outer end of each transmission rod is connected with an elastic press block. The elastic press blocks are connected with a sealing inner ring concave ring of a sealing inner ring, and a sealing inner ring convex ring of the sealing inner ring is attached to a sealing outer ring concave ring of a sealing outer ring. The locating disk and the transmission shaft are connected through an intermittent movement mechanism which is driven in a one-way mode. The sealing valve has the advantages of being simple in structure and good in sealing effect.

Description

【Technical field】 [0001] The invention belongs to the field of mechanical sealing valves, in particular to a uniformly distributed ring pressure sealing valve and a sealing method. 【Background technique】 [0002] At present, there are many types of sealing valves, which have problems such as complex structure, poor sealing effect, small application range, poor reliability, and complicated structural design of parts. 【Content of invention】 [0003] In order to overcome the problems existing in the prior art, the object of the present invention is to provide a uniformly distributed annular pressure sealing valve and a sealing method. The sealing valve of the present invention has the characteristics of simple structure and good sealing effect. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] Uniform ring pressure sealing valve, including positioning disc, sealing outer ring, elastic pressure block and sealing inne...
