Abstract
The utility model provides a filtration of H type vehicle air conditioner thermal expansion valve, includes valve body (1), connecting hole (2), feed liquor hole (3), is equipped with filter screen (4) between connecting hole (2) and feed liquor hole (3) or in feed liquor hole (3), can effectively prevent to get into the adjustment mechanism of H type vehicle air conditioner thermal expansion valve because of the impurity among the refrigerating system and cause card, stifled phenomenon, guarantees that H type vehicle air conditioner thermal expansion valve and refrigerating system normally work.
Description
Technical field
The present invention relates to a kind of filtration of H type automobile air-conditioning heating power expansion valve, belong to the throttling technology field of vapour compression refrigeration system, be specially adapted to the restricting element of air conditioner in car refrigeration system.
Background technology
The existing H type automobile air-conditioning heating power expansion valve of air conditioner in car refrigeration system that is used for is owing to there not being filtration, trace impurity in the Chang Yin system enters the governor motion of automobile air-conditioning heating power expansion valve and causes governor motion card or stifled, cause system's cisco unity malfunction, though in the air conditioner in car refrigeration system, be provided with dry liquid reservoir, it has the effect of certain impurity screening, but because the influence of various factors, can't fundamentally solve because of impurity and enter card, the stifled phenomenon that H type automobile air-conditioning heating power expansion valve governor motion causes.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in designly, simple in structure, can fundamentally solve because of impurity and enter the filtration that H type automobile air-conditioning heating power expansion valve governor motion causes card, stifled H type automobile air-conditioning heating power expansion valve.
The filtration of H type automobile air-conditioning heating power expansion valve of the present invention comprises valve body, connecting hole, inlet opening etc., it is characterized in that being provided with screen pack between connecting hole and the inlet opening or in the inlet opening.
Described screen pack can be conical or polygonal taper.
Described overanxious net also can be a hemispherical.
Described screen pack also can be cylindrical or polygonal cylindricality.
Described screen pack can also be disk or polygonal plane.
Described screen pack can be fixed with jump ring, is provided with the jump ring groove on valve body.
The also available gland of described screen pack is fixed.
The also available thread bush of described screen pack is fixed, and is provided with the screw thread that matches with thread bush on valve body.
Description of drawings
Accompanying drawing is the whole cutaway view of an embodiment of filtration of H type automobile air-conditioning heating power expansion valve of the present invention.
Shown in the figure:
1-valve body, 2-connecting hole, 3-inlet opening, 4-screen pack, 5-jump ring, 6-jump ring groove
The specific embodiment
The enforcement of the filtration of H type automobile air-conditioning heating power expansion valve of the present invention is very simple, and screen pack 4 is placed between connecting hole 2 and the inlet opening 3, and jump ring 5 embeds jump ring groove 6 interior can the finishing of valve body 1.
Owing between connecting hole 2 and inlet opening 3 or in the inlet opening 3, be provided with screen pack 4, impurity in the high pressure liquid refrigerant is filtered net 4 to be stopped, the governor motion of H type automobile air-conditioning heating power expansion valve can not be entered, H type heating power expansion valve and refrigeration system operate as normal can be guaranteed.
