specific Embodiment approach 1

[0007] Specific implementation mode one: as Figure 1-6 As shown, a one-way valve for an adjustable plunger pump in this embodiment includes a valve body 1, and also includes two semicircular valve covers 2, two rotating shafts 3 and two sets of sleeves 4, the valve The inner wall of the body 1 is provided with a boss 1-1, and a set of bushings 4 are symmetrically arranged at both ends of the upper surface of the boss 1-1, and a rotating shaft 3 is correspondingly inserted in each set of bushings 4, each rotating The shaft 3 is fixedly connected to the arc edge of a semicircular valve cover 2, and the two valve covers 2 are circular after closing, and each semicircular valve cover 2 is inserted with an adjusting bolt 5, and each adjustment The screw rod length L of the bolt 5 is R≤L≤3R, and R is the radius of the semicircular valve cover 2 . This embodiment prolongs the service life of the valve cover and reduces the production cost. In this embodiment, the opening angle of t...

specific Embodiment approach 2

[0008] Specific implementation mode two: as figure 1 and 3 As shown, several counterweight nuts 6 are provided at the lower end of the adjusting bolt 5 of the one-way valve for the adjustable plunger pump in this embodiment. In this embodiment, the opening speed of the semicircular valve cover 2 and the flow rate of the material can be adjusted by adjusting the number of counterweight nuts 6 . Other components and connections are the same as those in the first embodiment.

Abstract

The invention provides an adjustable check valve used for plunger pump, relates to a check valve and particularly relates to an adjustable check valve used for plunger pump which is designed for solving the problems in the existing plunger pump valve that the return quantity is large, the discharge quantity is small, the efficiency is low, the dimension of a switch cannot be adjusted according to the concentration of the material quantity, and the service life of a valve core is short. The adjustable plunger pump check valve provided by the invention comprises a valve body, two semicircular valve covers, two rotating shafts and two groups of shaft sleeves, wherein a bulged table is arranged on the lower end surface of the valve body; the two ends of the upper surface of the bulged table are respectively symmetrically provided with one group of shaft sleeves; one rotating shaft is correspondingly inserted into each group of shaft sleeve; each rotating shaft is correspondingly and fixedly connected with the circular arc edge of one semicircular valve cover; the two valve covers are in a circle after being buckled; one adjusting bolt is inserted into each semicircular valve cover; and the screw lengthL of each adjusting bolt is larger than or equal to R and less than or equal to 3R, and the R is the radius of the semicircular valve covers. The adjustable plunger pump check valve provided by the invention is used for opening or closing the circulation of the material in a material pipeline and controlling the flow of the material pipeline.

Description

technical field [0001] The invention relates to a one-way valve, in particular to an adjustable one-way valve for a plunger pump. Background technique [0002] The plunger pump is a pump that uses the piston to reciprocate in the pump cylinder to change the volume of the piston and the pump body, repeatedly sucking and discharging liquid and increasing its pressure. Therefore, the valve cover of the plunger pump valve needs to be opened and closed frequently. The valve cover of the existing plunger pump valve has slow switching speed, large return material volume, small discharge volume, and low efficiency. The limit point of the valve cover opening is fixed, and the size of the switch remains unchanged. The size of the switch cannot be adjusted according to the concentration of the material amount. , and the service life of the valve cover is short, which increases the production cost. Contents of the invention [0003] In order to solve the problems of the existing plun...
