Abstract

The utility model provides a sealing and silencing check valve with fast closing and a cone shape. The utility model comprises an upper valve body with a water inlet, a lower valve body which is connected with the upper valve body and is provided with a water outlet, and a guide post, wherein, the lower end of the guide post is arranged on a supporting seat which is arranged in the upper valve body and the lower valve body. The upper end of the guide post is provided with a guide sleeve which can slide along the guide post up and down. The guide sleeve is provided with a valve clack. The valve clack is provided with a sealing spherical surface cone which is matched with the water inlet of the upper valve body. Return springs are arranged on both ends of the guide post, and are tightly abutted with the supporting seat and the valve clack. The utility model has the advantages of simple structure, small volume, good sealing effect, long service life and small installation position, and is especially suitable for high-floor and low-floor water devices.

Description

Speed phragmocone body seals noiseless safety check
The utility model relates to a kind of safety check, particularly be that a kind of fast phragmocone body seals noiseless safety check.
Existing Tiny Drag Slow Shut Check Valves is that the operation by the transfer of individual event valve trace modulating valve and Slow Close cylinder, piston, pull bar reaches the Slow Close function.The Slow Close cylinder is big more, and the press water of piston back cavity is many more, and piston is released with recovery flexible more, and the Slow Close effect is good more.Otherwise bore is more little, and the Slow Close cylinder is just little, the back cavity press water is just few more, it is just dumb that piston promotes, and the Slow Close function is just malfunctioning, so that Tiny Drag Slow Shut Check Valves has a flap is light, open degree is big, power savings is remarkable, advantages such as water hammer is eliminated reliable performance, and sealing effect is good, but also exist volume big simultaneously, benzene is heavy, the shortcomings such as restriction of the floor space that is designed in the as installed.
In view of above reason, the purpose of this utility model be for provide a kind of simple in structure, volume is little, good sealing effect, long service life, mounting point fast phragmocone body little, that be applicable to high low layer water device seals noiseless safety check.
The purpose of this utility model is achieved like this: the utility model safety check comprises the upper valve body that contains water intake, the following valve body that contains water outlet that is connected with upper valve body, guide pillar on the supporting base about the lower end is contained in the valve body, the guide pin bushing that can slide up and down along guide pillar is equipped with in the upper end of guide pillar, flap is housed on the guide pin bushing, the ball sealer face cone body that matches with the upper valve body water intake is arranged on the flap, and return spring is contained on the guide pillar and two ends press closer on supporting base, flap (referring to Fig. 1).
Above-mentioned flap is made by rubber material, and its middle part is cored, and iron core is threaded with guide pillar (referring to Fig. 1), and is wear-resisting, and it is convenient to change flap.
The passage (referring to Fig. 1) that communicates with valve pocket is arranged, draining, noise elimination on the above-mentioned guide pillar.
Sealing (referring to Fig. 1) is arranged between above-mentioned upper and lower valve body.
The utility model is used for pump outlet and is attached thereto.When static, flap is that the water intake of upper valve body is closed.When playing pump, the WATER AS FLOW MEDIUM that is under pressure from pump promotes flap, and flap leaves the upper valve body water intake and opens, and finishes and send water conservancy project to do.Pipeline internal medium water is in a flash static when the power failure termination of pumping, and the return spring on the guide pillar promotes guide pin bushing and flap makes flap be in envelope position, pass.But because of flap closes envelope soon, the water that desire flows backwards in the valve body also can not flow backwards, and medium and water do not flow backwards, and just can not produce the impact force of backwater, just can not cause water hammer naturally, thereby reach noiseless.
The utility model is simple in structure, and volume is little, conservation, and good sealing effect, long service life, beautiful shape, the mounting point is little, and piping erection takes up space hardly, is highly suitable for high low layer water device.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, the upper valve body 2 that contains water intake 1 adopts bolt to be connected with 4 of the following valve bodies that contains drain opening 3, triangle supporting base 5 is arranged in upper and lower valve body, and guide pillar 7 one ends that contain the passage 6 that communicates with valve pocket stretch in the triangle supporting base and also with lock nut 8 it are fastened on the triangle supporting base 5.The outside of the flap 9 that employing rubber is made has the ball sealer face cone body 10 and its middle part that cooperate with the upper valve body water intake to be embedded with iron core 11.Guide pin bushing 12 upper ends that are contained in the guide pillar upper end are threaded with iron core 11 and can drive flap and slide up and down along guide pillar.Return spring 13 is contained in that its two ends press closer on flap and triangle supporting base on the guide pillar.O type rubber seal 14 is arranged between upper and lower valve body.
