TH18543B - Hydraulic inlet valve with low noise - Google Patents

Abstract

The invention revealed a valve that uses a pressure imbalance that creates flow. To keep the valve open or closed The valve has an internal cavity (15) where the inlet (12) and exits (13) which are opposite and straight open to them. The bulb-shaped valve body (16) is arranged inside the cavity. And was installed as a movement on the rod (17), which extends through the exit. The movement of the valve body increases the flow area at one end of the valve body. And reduces the area of flow at the other end of the valve body. According to Brenoulli, this alters the pressure acting on the valve body (16), which increases the net force per valve body. A bucket (111, 211) and a bucket (19).

Claims (7)

1. Valva contains Valve enclosures with inlet protrusions to the internal cavity And exits protruding from the inner cavity, with such entrances and exits quite opposite And a common bulb-shaped valve body, arranged within the cavity, and installed for approaching And exit from the said exit The valve body and the outlet are made to such a size that the outlet is blocked by the valve body. And a way to move around the valve that extends from the said valve Where the surface within the cavity And the external surface of the said valve body The pressure and flow are balanced in such valves in order to reduce the available cross-sectional area for flow to the outlet. And between the valve body and the said cavity And at the same time Increase the cross-sectional area obtained for the flow from the said outlet. And between the valve body of the cavity When the valve is moving towards the said exit. And vice versa When the valve body moves away from the said exit. The cavity and valve body alters the balance of the velocity of the flow causing the pressure exerted on the valve itself. 2. The valve as claimed in Clause 1, where the path for movement of the valve body as follows. It consists of a rod that extends through the said exit. The stem has a valve body installed on top of it. 3. A valve as requested in claim 2, where the stem is installed for its longitudinal movement. Hereby hold the rights in any one of the claims 1 to 3 Where the aforementioned exit consists of At least one exit channel The exit channel was curved. And extending around the inner cavity to the said entrance 5. Valves as requested in Clause 4, where such exits include a number of parallel-connected exit channels. The right to claim item 4 or 5, where the exit channel surrounds the inlet of the said valve. 7. The valve of any of the claims 1 to 6. Where the exit includes at least one opening connected to the atmosphere 8. Valves, as requested in claim 7, where the opening towards the atmosphere is blocked. When the exit is not blocked 9. Valve as requested in the claim 1 to 8 any one. Where the bulb-shaped body was selected from the group that included Egg-shaped, oval-shaped, and rankin-ovooloid 1 0. Water tank inlet valve, including one of the above claims 1 to 9 1 1. The water tank inlet valve includes the valve as requested in Clause 10 and installed at the top end of the stem. Contains an inlet for the said water tank 1 2.The water tank including the water tank inlet valve as requested in Clause 10 or 11 1 3. The flow control method is through a pressure and flow balance valve. And exits protruding from the inner cavity, where the inlet and outlet are relatively opposite. And a common bulb-shaped valve body arranged within the said cavity and the path for moving through the said valve body extending from the said valve body. The above method consists of steps The movement of the valve from the said exit. To increase the cross-sectional area available for the flow between the valve bodies And the cavity is adjacent to the said outlet and at the same time to reduce the cross-sectional area available for the flow between the valve bodies. And the said cavity adjacent to the said entrance This will supply the pressure causing the net flow to the valve body. Acted to cause the movement of the valve Away from the said outlet and open the said valve and the movement of the said valve to the said outlet. To reduce the cross-sectional area available for the flow between such valve bodies And the said cavity is adjacent to the said exit And at the same time to increase the cross-sectional area available for the flow between the valve bodies And the said cavity adjacent to the said entrance Which will supply the pressure causing the net flow to the valve body acting To cause the movement of the valve to the said exit. And shut off the said valve 1 4. Method, as in claim 13, where the valve body is moved through the equilibrium position. Where the pressure producing the flow is approximately equal to zero. 5. Methods as requested in Clause 13 or 14, including procedures for limiting the movement of the said valve body. Away from the said exit To prevent the valve body from coming into contact with such inlet 1 6. Method for the request for the right in any of Clause 13 to 15 Where the valve is the inlet valve to the water And the valve body is moved in response to the level of water inside the tank 1 7. Procedures as requested in Clause 16 include the procedure for connecting the said valve body to the float in the said tank. Through the float arms
