Abstract
The utility model discloses a plunger pump combined valve which belongs to a component of a plunger pump, particularly to a plunger pump combined valve. The plunger pump combined valve comprises a liquid charging valve cover, a valve seat, a liquid discharging valve cover, a valve board, a valve core, a liquid charging spring, a liquid discharging spring, a liquid charging sealing ring, a liquid discharging sealing ring, a bolt of the liquid charging valve cover, and a bolt of the liquid discharging valve cover. The utility model has the structure that the upper end and the lower end of the valve seat are respectively provided with the liquid charging sealing ring and the liquid discharging sealing ring. The utility model has the advantages that the integral valve seat in the prior art is improved to become the combined valve seat, so that the structures of the liquid charging valve cover and the valve core are improved, the use performance of the combined valve is raised, the service lives of the valve seat, the valve core, the liquid charging valve cover, etc. are prolonged, and lots of materials and costs are saved. Thereby, the product can be replaced under the condition that existing production enterprise does not need to be added with equipment.
Description
Affiliated technical field
The utility model belongs to a kind of parts of plunger pump, particularly the plunger pump combination brake switch and proporting.
Background technique
Reciprocating plunger pump is the common equipment that chemical enterprise pressurizes to liquid charging stock, original plunger pump combination brake switch and proporting mainly seals by the upper and lower end face of valve plate, spool and valve seat, in use repeatedly the gouging abrasion cocktail party is poorly sealed for the sealing surface of valve plate, spool and valve seat, though can turning, grind and repair, often can't repair, it is costly that valve plate, spool and valve seat all need replacing could repair at every turn, and consume a large amount of metallic material.
Summary of the invention
When providing a kind of the maintenance, the purpose of this utility model need not change the technological scheme of the novel plunger pump combination brake switch and proporting of whole valve seat.
The technical solution of the utility model is, the plunger pump combination brake switch and proporting, comprise, feed liquor valve bonnet, valve seat, discharge opeing valve bonnet, valve plate, spool, feed liquor spring, discharge opeing spring, feed liquor seal ring, discharge opeing seal ring, feed liquor valve covering bolt, discharge opeing valve covering bolt, its structure is: the valve seat upper and lower end is equipped with feed liquor seal ring body and discharge opeing seal ring body respectively.
The bottom of described spool is that circular seat, middle part are that conical seal (contact) face, its top are Y type directional post, and described discharge opeing valve bonnet center is the columniform discharge opeing spring strut of ladder.
The spacing of described feed liquor valve bonnet endoporus outer garden week and feed liquor seal ring mounting groove inner circumference is 4-5mm.
Because the combination brake switch and proporting technological scheme that the utility model provides heavily is improved to the new stack valve seat that upper and lower end is equipped with feed liquor seal ring body and discharge opeing seal ring body respectively with original whole valve seat.The seal ring body at two ends can adopt the mode of interference fit to be installed on the valve body, only changing seal ring body when wearing and tearing appear in sealing surface gets final product, need not to change valve seat integral body, seal ring body can adopt special high-abrasive material to increase the service life in addition, saves material and expense.Because the spacing of garden outside the feed liquor valve bonnet endoporus is all and feed liquor seal ring mounting groove inner circumference is increased to by original 2.5mm and is 4-5mm, can improve the working life that its shock resistance prolongs the feed liquor valve bonnet greatly.Extended to 5-10 by original 3-6 month the working life according to test feed liquor valve bonnet and valve seat, because spool has adopted the mode of inserting the valve seat inlet opening to improve neutrality made sealing surface prolongation in working life and is convenient to maintenance.
The beneficial effects of the utility model are that the whole valve seat with prior art is improved to stack valve seat and has improved the usability that the structure of feed liquor valve bonnet and spool has improved combination brake switch and proporting, prolonged the working life of parts such as valve seat, spool, feed liquor valve bonnet, save lot of materials and expense, existing manufacturing enterprise can realize model change under the situation that does not increase equipment.
