Problems solved by technology

This Chinese patent application solves the above problems, but after long-term use, the concentricity between the slide rod and its seal will gradually decrease due to wear and tear, which will lead to reduced sealing performance and even damage to the seal, affecting the sealing effect
[0004] On the other hand, the delivery pump using this slide valve will not only affect the discharge pressure due to the reduction of sealing performance, but also reduce its reliability and service life due to the wear of the slide rod seal.

Abstract

Provided is a carriage spool valve comprising: a main valve body (11) with a charging hole being provided therein; an auxiliary valve body (2) which is directly or indirectly coupled with the main valve body (11); a driving device (1) having a power output end; a dragged body (8) which is located between the main valve body (11) and the auxiliary valve body (2), a mounting hole being provided in the dragged body (8); a valve plate (9) which is mounted in the mounting hole of the dragged body (8) in an axially movable manner and blocks the mounting hole; and a through-hole body (6) which is mounted in the dragged body (8) and / or in a mounting hole of the main valve body (11) in an axially movable manner. A through-hole and an elastomer (7) are provided on the through-hole body (6), the elastomer being mounted in the mounting hole of the main valve body (11) and / or in the charging hole of the main valve body (11). The dragged body (8) is directly or indirectly connected to the power output end of the driving device (1) and can be driven by the driving device (1) to perform a reciprocating motion so as to open or close the charging hole in the main valve body (11). In addition, a delivery pump having the carriage spool valve is also disclosed.

Description

technical field [0001] The invention relates to the field of pipeline conveying equipment, in particular to a carriage slide valve used for pipeline conveying materials such as slurry and paste, and a conveying pump and a pump truck equipped with the same. Background technique [0002] In the pipeline transportation project of mud, concrete, coal slime, municipal sludge, printing and dyeing sludge, chemical sludge, liquid food raw materials and other materials, it is necessary to control the on-off and reversing of the conveying pipeline. The existing technology mainly uses liquid reversing Valves, but because these materials contain a large amount of solid components, and these solid components can easily enter the gap between the moving parts of the valve under high pressure, and even form accumulations, thus blocking the valve. [0003] In order to solve this problem, the inventor of this patent has developed a new type of valve, see Chinese Patent Application No. 2015108...
