Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-3, the utility model discloses a take plunger pump outlet check valve of throttle structure, including pump cover 1, supporting seat 2, spring 3 and steel ball 4, supporting seat 2 installs on pump cover 1, processing has horizontal orifice 5 on supporting seat 2, the inboard processing of supporting seat 2 of horizontal orifice 5 department has technology flow channel hole 7, horizontal orifice 5 flows out the space intercommunication through a technology flow channel hole 7 and check valve, valve port 8 has on supporting seat 2, 8 departments of valve port are formed with conical surface 6, steel ball 4 installs on the conical surface 6 of supporting seat 2, spring 3 installs at pump cover 1 hole, spring 3 tip contacts with steel ball 4, spring 3 is located between 1 hole of pump cover and the steel ball 4. The spring 3 forces the steel ball 4 to block the conical surface of the valve port 8.
In order to make supporting seat 2 and pump cover 1 assemble more firmly, supporting legs 21 of supporting seat 2 inlays in the kerve 11 of pump cover 1.
The process flow channel orifice 7 is a longitudinal orifice. One end of the longitudinal hole is communicated with the transverse throttling hole 5, and the other end of the longitudinal hole is communicated with the cavity space between the pump cover 1 and the supporting seat 2.
The transverse throttle bore 5 is used externally for connection to the load side.
Under the action of the reset spring force in an initial state, the spring 3 enables the steel ball 4 to block the conical surface 6 of the valve port 5, and the valve port is closed; when the pressure of the inner cavity of the supporting seat 2 is higher than the load pressure, the one-way valve is opened against the action of the reset spring force, and high-pressure fluid in the inner wall of the supporting seat is discharged.
The orifices in the support block 2 can be designed precisely to different lengths and diameters to match different pump displacements.
Compared with the prior art, the pump cover 1 is not provided with a throttling oil groove, machining is convenient, the supporting seat 2 is provided with the transverse throttling hole 5, relative mechanical manufacturing is easy, the throttling area of the transverse throttling hole is easy to calculate, the inner side of the supporting seat 2 at the position of the transverse throttling hole 5 is provided with the process flow passage hole 7 in a machining mode, the process flow passage hole 7 is a longitudinal hole, and therefore the transverse throttling hole 5 is communicated with the flowing space of the one-way valve through the longitudinal hole, and pressure of fluid can be better controlled.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
