Abstract
The utility model discloses a driven four-way electromagnetic reversing valve used by multi-functional heat pump system, which comprises a main valve body, an input port, an output port, two reversing ports, two pistons, a piston connection rod, fixed screws of the piston and the piston connection rod, a reversing sliding block, and an electromagnetic control valve, the calibers of the two reversion ports of the input port and the output port are the same, the bottom part of the two fixed screws of the piston and the piston connection rod is provided with 8-shaped orientation lock sheet, the four-way electromagnetic valve with the structure has characteristics of small countercurrent low pressure air resistance of the input port and repeated instantaneous reversing impact resistance.
Description
Technical field
The utility model relates to a kind of heat pump four-way electromagnetic reversing valve, and more particularly, it relates to the driven four-way electromagnetic reversing valve that a kind of multipurpose heat pump system uses.
Background technique
Existing heat pump constitutes as shown in Figure 1 with retaining screw, commutation slide block and the control electromagnetic valve of four-way electromagnetic reversing valve by main valve body, inlet opening, two commutation mouths, two pistons, piston rod, piston and piston rods; Its working state has only two kinds shown in Fig. 5 (a) and (b), and its inlet opening is only done the pressurized gas input and used, for the matching of pipeline, so its inlet opening specific output mouth and commutation mouth are little; Secondly existing heat pump is less with the actual commutation of four-way electromagnetic reversing valve access times, and seldom carries out switch operation in working state of system, so its shock resistance design is relatively poor; The driven four-way electromagnetic reversing valve working state that the multipurpose heat pump system uses requires there are four kinds shown in Fig. 6 (c), (d), (e), (f), its inlet opening is that low-pressure gas output is done in the pressurized gas input again, when so existing heat pump is in low-pressure gas output state as the driven four-way electromagnetic reversing valve of multipurpose heat pump system in the inlet opening with four-way electromagnetic reversing valve, can the Energy Efficiency Ratio of whole system be descended because of the too small increase low pressure of its inlet opening caliber vapour lock; Because the inlet opening of driven four-way electromagnetic reversing valve is connected with the commutation mouth of conventional heat pump with four-way electromagnetic reversing valve in the multipurpose heat pump system, the inconsistent size of two bores can increase the difficulty of welding when making again; Multipurpose heat pump is many with the commutation access times of four-way electromagnetic reversing valve, and most switch operations that in working state of system, carry out, so its access times and shock resistance are had relatively high expectations, therefore existing heat pump does not reach driven four-way electromagnetic reversing valve in the multipurpose heat pump system with four-way electromagnetic reversing valve usability requirement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the driven four-way electromagnetic reversing valve that provides a kind of multipurpose heat pump simple in structure, function admirable to use.
Driven four-way electromagnetic reversing valve of the present utility model, be achieved by following technical proposals, the utility model comprises retaining screw, commutation slide block, the solenoid electric valve of main valve body, inlet opening, delivery outlet, two commutation mouths, two pistons, piston rod, piston and piston rods, the bore of its inlet opening, delivery outlet and two commutation mouths is identical, the retaining screw head of piston and piston rod is a square, and 8 fonts location locking plate is equipped with in the bottom.
Driven four-way electromagnetic reversing valve of the present utility model is than existing heat pump four-way electromagnetic reversing valve, is used for the multipurpose heat pump system following beneficial effect of having compared:
1, inlet opening adverse current low-pressure gas resistance is little, strengthens multipurpose heat pump entire system technical performance;
2, the caliber matching is good, reduces the welding difficulty, reduces manufacture cost;
3, anti-ly repeat instantaneous reverse and impact, prolong four-way electromagnetic reversing valve working life.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
On the basis of heat pump with four-way electromagnetic reversing valve main valve body 1 of prior art, the bore standard of pressing delivery outlet 3 or commutation mouth 4,5 increases its inlet opening 2; The heat pump of prior art is removed with the piston of four-way electromagnetic reversing valve and the retaining screw of piston rod, change quadrate silk head screw, and install the 8 fonts location locking plate that copper or iron are made in its bottom additional, after screw tightens the outward edge of 8 fonts location locking plate is levered up locking and gets final product by being parallel to a square silk head edge.
Design feature:
1, uses on the basis of four-way electromagnetic reversing valve at the heat pump of prior art, need not just change greatly and can make, save Cost;
2, the anti-repetition instantaneous reverse of the driven four-way electromagnetic reversing valve impact property used of novel multi-purpose heat pump system significantly Strengthen, prolong four-way electromagnetic reversing valve service life.
Claims (3)
1. driven four-way electromagnetic reversing valve that the multipurpose heat pump system uses, the retaining screw, commutation slide block, the solenoid electric valve that comprise main valve body, inlet opening, delivery outlet, two commutation mouths, two pistons, piston rod, piston and piston rods, it is characterized in that, the bore of described inlet opening, delivery outlet and two commutation mouths is identical, and the location locking plate is equipped with in the retaining screw bottom of described piston and piston rod.
