Abstract
The utility model relates to a plastic hydrodynemic valve which is a plastic hydrodynemic valve, and the utility model is an improved normally open executive valve which is used for shutting. An existing executive valve is made of metal materials and is manually operated, has the defects of poor corrosion-resisting property, low efficiency, and poor accuracy. The utility model is made of ABS plastic. A valve cock, a diaphragm, and a venting hole which are in the valve cavity are utilized and combined with an intermediate controlling valve and an electric controller, and the liquid pressure in the main channel is directly utilized as dynamic force to drive the valve cock automatically open and semi-close the valve. The utility model has the advantages of corrosion resistance, simpleness and reliability, high control accuracy, and automatic control.
Description
The utility model is to be used for the water-treating equipment system, a kind of controlling plumbing fixtures flow of fluid automatically perform valve---plastics hydraulic operated valve.
At present general Chang Kaiguan closed form is carried out valve by manual operation, and control accuracy is poor, and efficient is low, and generally adopts metallic material to make, and decay resistance is also poor.
Task of the present utility model is to overcome above shortcoming.The utility model and intermediate controlled valve, the supporting formation control system of electrical-controller.It is characterized in that by electrical-controller output electrical signal.Handle the intermediate controlled valve, and then the control hydraulic operated valve carries out the task of opening or cutting out the main passage.The intermediate controlled valve connects main passage and hydraulic operated valve uuper valve chamber by tubule.The liquid that injects uuper valve chamber comes the interior pressured fluid of autonomous channel, determines to inject or stop injection by the intermediate controlled valve.The bibcock that utilization is provided with in valve pocket, barrier film, vent etc. make closing and open fully according to the instruction of electrical-controller and intermediate controlled valve and utilizing in the main passage pressure of liquid to finish of hydraulic operated valve.Very simple and reliable, realized automatic control.Because valve body, valve gap, valve pocket lining, bibcock etc. all adopt ABS plastic to make, so also have excellent corrosion resisting performance.
The utility model will be illustrated more clearly in the accompanying drawing of the following example.
Hydraulic operated valve is made up of valve body 20, valve gap 4, bibcock 7, valve pocket lining 16, barrier film 13, punch holder 12, die holder 14, seal ring 3, adjusting screw 8 etc.Bibcock 7 is divided into uuper valve chamber 6, middle valve pocket 5 and 17 3 parts of lower valve chamber by barrier film 13, punch holder 12, die holder 14 and valve pocket lining 16 with valve pocket.By tubule and the intermediate controlled valve 10 that links to each other with spout 9 on valve gap at the conduction hole 18 that communicates with main passage 19 on the valve body, accept pilot signal from electrical-controller 11.When electrical-controller 11 is exported " closing " signals, intermediate controlled valve 10 is open-minded.Pressured fluid in the main passage 19 injects uuper valve chamber 6 by intermediate controlled valve 10, because the pressure-bearing work area in uuper valve chamber 6 that is made of bibcock 7, punch holder 12, barrier film 13 is designed to greater than the pressure-bearing work area in lower valve chamber 17 that is made of bibcock 7, seal ring 3, screw 2, thereby produced the pressure that bibcock 7 is passed toward lower valve chamber 17 by uuper valve chamber 6, make seal ring 3 press to supporting surface 1.Closed main passage 19; When electrical-controller 11 output " open-minded " signals, intermediate controlled valve 10 cuts out, blocked of the injection of main passage 19 interior liquid to uuper valve chamber 6, liquid is let out yearningly via the duct of opening simultaneously in the intermediate controlled valve 10 in the uuper valve chamber 6, pressure-bearing working surface upward pressure falls sharply in the uuper valve chamber 6, liquid back down bibcock 7 by self pressure in the main passage 19, have realized the unlatching of hydraulic operated valve.
Barrier film 13 energy hermetic barrier uuper valve chamber 6 and the middle valve pockets 5 that valve gap 4 and valve body are 20 flow in the valve pocket 5 liquid that can not that injects uuper valve chamber 6, also can not overlap 16 glade plane space inflow lower valve chamber 17 through bibcock 7 and valve pocket village.Barrier film 13 is fixed on bibcock 7 upper ends by punch holder 12 and die holder 14, constitutes bibcock 7 upper end working surfaces.Seal ring 3 usefulness screws 2 are fixed on the lower end of bibcock 7, constitute bibcock 17 lower end working surfaces.When bibcock 7 during to lower slider, the air in the middle valve pocket 5 is discharged by vent 15,
When the valve opening amount need be regulated, can utilize the stainless steel adjusting screw 8 of design in valve gap 4 central authorities, regulate the displacement distance of bibcock 7, reduce or increase the open amount of valve.
Claims (3)
1, a kind of plastics hydraulic operated valve, it is characterized in that the bibcock 7 in its valve pocket passes through barrier film 13, valve pocket lining 16 divides uuper valve chamber 6 with valve pocket, middle valve pocket and 17 3 parts of lower valve chamber, spout 9 is arranged on the valve gap 4, accept in the autonomous channel 19, through the conduction hole on the main passage 19 18, the flow through pressured fluid of two sections tubules and middle control valve 10, there is vent 15 to communicate on the middle valve pocket with atmosphere, bibcock 7 is slided freely, lower valve chamber 17 is constituent elements of main passage 19, the seal ring 3 and the supporting surface 1 of bibcock 7 lower ends match, and when seal ring 3 was fitted with supporting surface 1, main passage 19 was closed; During separation, main passage 19 is open-minded, and main passage 19 is opened or closed to bibcock 7 by injecting or stopping to inject the pressured fluid in the autonomous channel 19 to be determined in uuper valve chamber 6; Barrier film 13 is fixed in bibcock 7 upper ends after clamping by punch holder 12 and die holder 14, constitute bibcock 7 upper end working surfaces, barrier film 13 edges are fixed by screws clamp by valve gap 4 and valve body 20, screw 2 is fixed in seal ring 3 lower end of bibcock 7, constitute bibcock 7 lower end working surfaces, the upper end work area of bibcock 7 forms a up big and down small cylinder stepped shaft greater than the lower end work area.
2, plastics hydraulic operated valve according to claim 1 is characterized in that barrier film 13 makes for rubber material.
3, plastics hydraulic operated valve according to claim 1 is characterized in that valve body 20, valve gap 4, bibcock 7, punch holder 12, die holder 14, screw 2, valve pocket lining 16 are ABS plastic and make, and the adjusting screw 8 of valve gap 4 central authorities is made for stainless steel.
