Abstract
The utility model discloses a business turn over water structure of plunger high-pressure pump, including plunger pump, inlet channel, the check valve that intakes, outlet conduit and play water check valve, the check valve that intakes and play water check valve arrange between inlet channel and outlet conduit, and the check valve that intakes makes inlet channel and outlet conduit by the inlet channel to outlet conduit one-way switch on, and the check valve that intakes and play water check valve respectively with plunger chamber UNICOM, the check valve that intakes and the one-way coaxial range of play water check valve. The utility model discloses a water inlet check valve and play water check valve are coaxial from top to bottom, and the space occupies for a short time, and liquid volume is little, under the same input power state, does work still less to the compression of liquid, and work efficiency is higher, and through bumping the perforation intercommunication between water inlet check valve and the play water check valve and the plunger chamber, the simplified course of working shortens process time, has reduced the loss, and the assembly is more simple.
Description
Technical Field
The utility model relates to a business turn over water structure, concretely relates to business turn over water structure of plunger high-pressure pump.
Background
The existing plunger type high-pressure water pump is generally provided with inlet and outlet one-way valves which are arranged vertically, parallelly or crossly, the distance between the inlet and outlet one-way valves is large, the arrangement space is loose, water channels for inlet and outlet water are generally formed by die-casting into solid shapes, then the channels are communicated by machining, the machining process is complicated, the period is long, and the cost is high.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a business turn over water structure of plunger high-pressure pump solves to arrange between the current business turn over water valve loosely, and the distance is big, occupation space's problem.
The technical scheme is as follows: the utility model aims at providing an business turn over water structure of plunger high-pressure pump, including plunger pump, inlet channel and outlet conduit, be provided with business turn over water valve device between inlet channel and the outlet conduit, business turn over water valve device and plunger pump intercommunication, business turn over water valve device includes coaxial vertical setting at the interior check valve of intaking and the check valve that goes out of a passageway, intake check valve and inlet channel intercommunication, go out water check valve and outlet conduit intercommunication.
The water inlet and outlet valve device is communicated with the plunger pump through the collision perforation.
The water outlet one-way valve is coaxially arranged above the water inlet one-way valve.
The water inlet one-way valve comprises a valve body and a valve core, wherein a through hole communicated with a water inlet pipeline is formed in the bottom of the valve body, the valve core is installed in the valve body, one end of the valve core is abutted to the through hole in the bottom of the valve body, and a spring is installed at the other end of the valve core.
The mounting channel of the water inlet and outlet valve device is a channel formed in one step by adopting a die-casting die.
Has the advantages that: the utility model discloses a water intaking valve and outlet valve are coaxial from top to bottom, and the space occupies for a short time, and corresponding installation passageway all is die casting die one shot forming, has not passed through secondary operation, passes through between business turn over water valve device and the plunger pump and bumps the perforation intercommunication, simplifies the course of working, shortens process time, has reduced the loss.
